Junior – Physical Science (JPS) – 6th Grade Project Number: JPS100 Grade: 6 Title: Kitchen Crime Lab Abstract: The purpose of this project is to see if DNA can be collected and analyzed with household items. I used strawberries, bananas, onions, and wheat germ. First, I crushed and filtered the food sample. Then I added a detergent buffer solution to break the cell wall and expose the DNA. Chilled alcohol was added to precipitate the DNA. I collected the DNA and added a running buffer and placed it in the wells of the gel in the electrophoresis tank. Power was applied to the tank using 9V batteries. The gel can be dyed with methylene blue to show the bands of DNA. I ran many tests and was not able to produce visible bands of DNA. Project Number: JPS101 Grade: 6 Title: Disaster Over Time Abstract: It seems that we hear about a lot of natural disasters happening recently. This lead to questions, Are they really happening more often?Are natural disasters getting worse? My opinion is that, they are getting worse. To be sure I decided to do some research to find out more about it. I want to have more information about natural disasters, the weather that creates them, how they are categorized, if they are occurring more frequently, how to observe climate and weather, and how to be more prepared. I wll start with reading and reporting on six different natural disasters: tsunamis, earthquakes, torndos, hurricanes, volcanoes, and floods. I will list their major features, what causes them, and how they are rated. Then I will do some internet research on these six disasters over the last fifty years and record this information for my data. The data will be presented on a timeline, line graph, and bar graph. I think my research will show that natural disasters are getting worse. Finally, I will be present information about how to observe the local clomate and wather, how to build a homemade weather station, and how to be prepared for natural disaster emergencies Project Number: JPS102 Grade: 6 Title: Throwin' It Far Abstract: Which method of throwing a soccer ball (standing still or running) will give you a better distance? My hypothesis is that running will increase the distance of a throw. My procedures include having ten soccer players take five of each throw. I will then average this number in both. My data shows a increase in the running category with throws big as twelve meters. My hypothesis is correct. Running will increase the distance of a throw. After taking averages, every player had a higher average in the running category. The difference in the categories was twenty-one percent. Project Number: JPS103 Grade: 6 Title: Aerodynamic affect of football Abstract: NFL Quarterbacks throw long, accurate, perfectly spiraling passes to their receivers, but why are the only thrown a certain way by every great quarterback? This project investigates the best way to throw a football. The grip, release, and force were constant. The motion of the football, as it traveled through the air, was the variable. The distance was measured and recorded in a data table. My hypothesis was If I threw a football with a spiral spin along its long axis, it PRSEF Student Abstracts Page 1 Junior – Physical Science (JPS) – 6th Grade will go a longer distance than throwing a football with an end-over-end (wobble) motion. The experiment results supported my hypothesis. Project Number: JPS104 Grade: 6 Title: King of the Liquids Abstract: The purpose of my experiment is to find out which liquid makes the crown shape the best when you drop them. My hypothesis was that the liquids that are viscous will not make a crown shape, and the liquids that are not viscous will make a crown shape. I found out by dropping the liquids on a plastic sheet with a dropper and looking at the shape they make right after they touch the sheet. My hypothesis was correct. Project Number: JPS105 Grade: 6 Title: How Should I Wash It? Abstract: The purpose of my experiment is to find out whether or not clothes elastic is damaged by laundry detergents. To conduct my experiment, I will first test the elasticity of the elastic. Second, I will soak the elastic in a laundry detergent for several minutes. Third, I will dry the elastic with a dryer. Lastly, I will retest the elasticity of the elastic. I will use this data to form my conclusions. The results will be available on fair day. Project Number: JPS106 Grade: 6 Title: How High Does a Soccer Ball Bounce? Abstract: I tested the effects of height (potential energy) on how far a soccer ball would bounce when dropped. My hypothesis was that if I drop a soccer ball from different heights, it will bounce differently depending on the height dropped. I dropped the soccer ball from different heights and measured the distance it bounced off the ground. My hypothesis was supported because I found that the distance the ball bounced was directly linked to the distance from which it was dropped. Project Number: JPS107 Grade: 6 Title: Foam vs. Impact Abstract: The purpose of my project is to find out which foam type reduces the impact of the baseball the best. It really will answer the question which foam type would be best for free falling situations such as stunts in movies. I conducted this experiment by testing the impact of a baseball dropping from a measured height onto a scale. The three products tested on the scale were: Evlon foam, Memory foam and foam rubber. I constructed a “trapdoor” for the baseball so it constantly landed on the center of the scale. I hypothesized that the Evlon Foam would reduce the impact the most, and my conclusion was that it did. My choice was the Evlon Foam because it had enough firmness and consistency to stay in place and absorb the impact of the baseball. PRSEF Student Abstracts Page 2 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS108 Grade: 6 Title: Does table salt melt ice better then any other substance? Abstract: Project Title: Does table salt melt ice better then any other substance? What I did for the project is, got the materials needed for the project, and then filled up 6 ice trays. Then added the substances to it. waited a hour then repeated the process again. The Hypothese that I made was wrong: Is table salt the best material for melting ice, it was the road salt that melted it the best. Conclusion - The table salt is not the best material for melting ice Project Number: JPS109 Grade: 6 Title: Power of Wing Size Abstract: The purpose of this project was to determine if the length of a wingspan would affect how far an airplane would fly. I thought that the longest wingspan would make the airplane fly the farthest. The wingspan lengths were 120cm, 140cm, and 180cm. I launched them on a wood runway by making a rubber band sling shot to pull back and launch. I had some measuring tape out in front to see how far the plane did travel. Last I recorded the length that each wingspan went and determined that my hypothesis was incorrect. The smallest wingspan went the farthest distance. The second furthest plane was the 140cm wingspan. The last was the longest wingspan. Project Number: JPS110 Grade: 6 Title: What's Up with the Ring of Fire? Using Plate Tectonics to understand why there are so many volcanoes surrounding the Pacific Ocean Abstract: Have you ever wondered why the RIng of Fire is so volcanic? For this project, I read about plate tectonics and volcanoes to understand why the Ring of Fire exists. I hypothesized that the tectonic plates in the Ring of Fire were more active than the plates that make up the rest of the world. To collect my data, I used different databases and techniques to calculate plate movement in the ring of fire compared to elsewhere. These data suggest that, indeed I was right. The tectonic plates move 5 to 7 centimeters more per year than the plates outside the ring of fire. If your travels take you to the ring of fire, beware. Project Number: JPS111 Grade: 6 Title: The Energy Throw Abstract: The purpose of this experiment is to find out if energy drinks affect the speed and accuracy of a football throw. To conduct this experiment I compared the speed and accuracy of the throw with the energy drink and without it. The experimental results were measured by having my subjects throw a football at a target and measuring the speed with a speed gun. The results of this experiment showed that energy drinks do increase the speed and accuracy of the throw. The results indicate that the hypothesis should be accepted because the energy drinks did increase the speed and accuracy of the throw. PRSEF Student Abstracts Page 3 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS112 Grade: 6 Title: Which Broadhead Penetrates the Deepest? Abstract: One of my favorite things to do is hunt deer with my bow. I am curious about which type of broad head penetrates a target the deepest. I will test 3 different broad heads: Muzzy, Real Tree Lightning, and Rage. I will determine which broad head penetrates the deepest by shooting them at a target 3 times each. I will choose an isolated area. My hypothesis is that the Rage will penetrate the deepest. Project Number: JPS113 Grade: 6 Title: Making Crystals: What is the Best Environment Abstract: Identifying the best temperature & circumstances to grow crystals and determining which growth environment produces the best crystals. Will the ice bath method, refrigerator method or room temperature method produce the best crystals? If I place the jar of water in the ice bath, then the solution will crystallize large, pure crystals. My hypothesis was correct. Crystals that are meant to be pure should be grown in ice bath-like temperatures, because the results are this type of crystal: pure and large. Other temperatures, such as the room and refrigerator temperatures, will not crystallize these crystals. Project Number: JPS114 Grade: 6 Title: Fruits and Veggie Power Abstract: I will use different types of fruits and vegetables and test the amount of voltage they produce. My hypothesis is that I believed the lemon will produce the most voltage. I will use three fruits and three vegetables. Take the fruits and vegetables and press them on the table to loosen the juices. I will then cut them in half and place a galvanized nail and penny in them. I will use a multi-meter to test the voltage. The conclusion I came to while doing my project was somewhat true to my hypothesis, that lemons will produce the most voltage. Project Number: JPS115 Grade: 6 Title: Particle Pollution Patrol Abstract: What variables affect the amount of air particles in a room? This is the question I answered in my project. I tested five rooms plus a closed box (control). My hypothesis was that the Living Room and Bedroom would have the most air particles. To experiment I hung up particle "traps" in my planned rooms. I made the traps by dividing a poster board into smaller sections, drawing a square inside each section, and spreading Vaseline inside each square to catch particles. I hung them up to experiment. My conclusion was that the closet and bedroom had the most particles. Project Number: JPS116 Grade: 6 Title: Shaking for Suds Abstract: In my project, I hypothesized that tap water would make the most bubbles. It is the water we use everyday to wash and clean with. I tried the experiment with three types of water. I was surprised by the results. The three types of water that I used were tap water, mineral water, PRSEF Student Abstracts Page 4 Junior – Physical Science (JPS) – 6th Grade and distilled water. I filled three identical plastic containers with equal amounts of each type of water. I added drops of dish washing soap with an eyedropper. I put the lid on the containers and shook each one. Then I repeated the process, counting the number of drops I used to make the bubbles reach the top of each container. I wanted to do this to see which types of water were hard and would make less bubbles and which types of water were soft and would make more bubbles. In conclusion I saw that there really was not much difference in the types of water that I used. They all seemed to make bubbles with almost the same amount of drops of dish washing soap more or less. I did notice that on one of my trials the distilled water seemed to make bubbles with less dish washing soap than the other types but not by that much difference. Project Number: JPS117 Grade: 6 Title: In What Liquid Does Ice Melt the Fastest? Abstract: In what liquid does ice melt the fastest? The purpose for my project is that if you ever wanted to have a party and serve ice-cold drinks, this experiment would help you. I tested 6 liquids: water, Gatorade, Snapple, Coke, milk, and orange juice. Equal amounts of ice were added to each liquid and melting times were recorded. Each liquid was tested 10 times. My hypothesis was that Coke would have the ice melt the fastest in it because of the chemicals that would break the ice down. My hypothesis was proven incorrect: water melted the ice fastest by far. Project Number: JPS118 Grade: 6 Title: Water vs. Waterproofing Abstract: The purpose of my experiment is to see which substance holds water back the best: putty, duct tape, or Scotch tape. I hypothesized that putty would hold back the most water and be the best substance to prevent leaks. I cut a hole in each of 3 identical containers. I would apply duct tape to one container, putty to another, and Scotch tape on another. I filled each container with water and observed for three hours. I then recorded how much water was left in each container. I then repeated each test four more times. It turned out that putty and Scotch tape held water back completely, but duct tape let the water through. I did my experiment five times. Project Number: JPS119 Grade: 6 Title: What Type of Water Makes Brine Shrimp Grow Faster? Abstract: My project tested what type of water (one with baking soda, one without) would make brine shrimp grow faster. My hypothesis was that the baking soda water would grow them faster because baking soda will form the eggs faster. Using 2 liter water bottles, I added baking soda into one and added the brine shrimp powder. The brine shrimp did not hatch so I am planning to conduct another experiment. Possible sources of error are the water or room temperature. PRSEF Student Abstracts Page 5 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS120 Grade: 6 Title: Do Energy Drinks Affect Pea Plant Growth? Abstract: I wanted to know if you could use energy drinks as fertilizer for pea plants. My hypothesis was that energy drinks will increase plant growth because of the ingredients in energy drinks. I Planted 4 separate seeds. I used 3 different types of energy drinks (Rock Star) to feed 3 plants and used water to feed the control plant. My hypothesis was not supported because the water grew the plant better. Therefore energy drinks don't grow plants well. Project Number: JPS121 Grade: 6 Title: Do Energy Drinks Affect Plant Growth? Abstract: My project tested effects of energy drinks on plants. My hypothesis was: If plants are given an energy drink as opposed to water, they would grow slower because water will allow them to grow faster because it is pure and has the nutrients that a plant needs for optimum growth. I planted 3 separate sunflower seeds. One was fed with water and the other 2 were fed with energy drinks (Gatorade/Monster) for 12 days. My hypothesis was supported becuase I found that energy drinks retards plant growth. Project Number: JPS122 Grade: 6 Title: Buoyancy Abstract: My question is when more water is added, will it make the submarine sink, rise, or stay at the same level in the water? My hypothesis was proven correct, because when more water was added, it did make it sink. Take a 710mL bottle and mark out 60mL, 120mL, etc. Then add water to each level to see if it sinks, rises or stays the same. Keep a log of the results that were found during the trials. If the submarine stays above water, it is positive buoyancy. If it goes under water, it i negative buoyancy. If the level stays the same, it is neutral buoyancy. Based on the results, buoyancy was reduced when more water was added causing the submarine to sink. Project Number: JPS123 Grade: 6 Title: Sticky Science Abstract: Abstract I decided to do a project with different types of glue when a chair at my house needed fixed and the glue my mom bought did not work. The purpose of my experiment is to find which type of glue works best. The procedure I used was to pick four different glue types. I picked Gorilla Glue,Super Glue,Elmer's Glue-All ,and Wood Glue. The data I collected in chart form. I wrote down the tac-time and dry-time. My conclusion, I found that a glue is made for different things. Gorilla Glue is the best overall glue Project Number: JPS124 Grade: 6 Title: AROMATHERAPY: Will people be able to distinguish through preference between natural and artificial aromatherapy smells Abstract: Aromatherapy has become popular in mainstream America in recent years, and people use it for many reasons including mood management, mental clarity, and stress reduction. In this experiment, human subjects will be tested for preference in distinguishing between natural and PRSEF Student Abstracts Page 6 Junior – Physical Science (JPS) – 6th Grade artificial aromatherapy smells. The experimenter selected three fragrances-lavender, peppermint, and lemon-and set up a testing station with blindfolded subjects. Six samples were presented: three natural, three artificial. The experimenter had each subject smell each fragrance, varying starting with natural and artificial. The overall results, 14 (natural) to 7 (artificial), showed human preference in choosing natural aromatherapy smells twice as often during this experiment. Project Number: JPS125 Grade: 6 Title: How long does pop keep it's carbonation? Abstract: The reason I did this project was because when I drink pop my parents normally tell me it is out of fizz but I don't really know if it is so this will really tell me if the pop is flat or not. My testable question is how long does it take pop to lose its carbonation. My hypothesis is if temperature is related to carbonation loss than the colder the temperature the less carbonation that is lost. My procedure was I had 16 bottles of pop & I put 4 of them in each room, & each day for 7 days I measured the weight, the pH, & how much it tasted like a brand new bottle of pop. The pop in the refrigerator had the most carbonation in the end, then the basement, then outside, & lastly my bedroom. My hypothesis was right because the refrigerator was the coldest spot & there was the most carbonation in the pop in the refrigerator. Project Number: JPS126 Grade: 6 Title: Breaking Down Bones Abstract: The purpose of my experiment is to determine if either base or acid dissolves chicken bones faster. For this experiment, I used Coke and lemon juice for acidic liquids, baking soda solution and window cleaner for basic liquids and water for the control set up. First I weighed each chicken bone and recorded the mass. Then, I put the bones in these liquids in 6 plastic cups. Then I observed these chicken bones once a week for 3 weeks. My hypothesis was the acidic Coke would dissolve the chicken bones. However my hypothesis was totally wrong! All the bones got bigger and weighed about 2 times more. I learned that bones are very porous. Project Number: JPS127 Grade: 6 Title: The Rust Race Abstract: In my project I wanted to see what liquids made nails rust fastest. My independent variables are bleach, water, Mt. Dew, and vinegar. I thought that the bleach would rust the nails the fastest. I weighed 12 nails and recorded the masses. I then soaked 3 nails in each of the 4 liquids. I made observations each day. The bleach was the first liquid to make the nails rust and the rusting started in the first three hours of the project. After a determined time period, I removed that nails and weighed them and recorded the masses. Most of the liquids were slow to cause rusting but my hypothesis was proven correct Project Number: JPS128 Grade: 6 Title: Super Deluxe Pitch Abstract: The subjects I have been studying for my project are sound, sound waves, and changing of pitch in sounds. The purpose of my experiment was to find how the frequency of PRSEF Student Abstracts Page 7 Junior – Physical Science (JPS) – 6th Grade sound relates to the pitch of sounds. To do my experiment, I downloaded an oscilloscope app for my iPad. Next, I tested different lengths of metal conduit, starting at 4 inches and ending at 16 inches, adding 2 inches at a time. I used information I got from the socilloscope to calculate each of the length's frequency in Hertz. I used the data I collected to make my conclusion that the longer the metal chimes were, the lower the frequency was, and the lower the pitch was. Project Number: JPS129 Grade: 6 Title: How Crystals Grow Abstract: I decided to grow crystals in different tmeperatures to see which would grow the larger clearer crystal. I made a solution of slat and one of sugar. I placed one of each in three different temperatures and compared the growth. My result was very upsetting at first, I could not figure out what I did wrong. I made a few adjustments and waited 2 more weeks and then I finally got a result. I will do the experiment again and try different solutions, coloring and flavors. Project Number: JPS130 Grade: 6 Title: To Float or not to Float Abstract: The purpose of my experiment was to see if you could make an object float better by making changes with density. During my experiment I used three main materials:clay, aluminum foil, and playdough. First I put each item, one at a time, (in a ball shape)into a bowl of water. Only the foil ball stayed afloat. Then I put the items back in the water. This time they were in a boat-shape. Only the foil and clay boats floated. In the end I decided that you could make certain items float better by making density changes. Project Number: JPS131 Grade: 6 Title: Will it Take 3 or 4 Lemon Batteries to Power a LED? Abstract: This project was designed to see if it would take 3 or 4 lemon batteries to power a LED.According to my research, three lemons should create 2.6 volts of electricity. I inserted a penny/brass and galvinized nail into the lemons and connected a wire to the penny/brass and nail and tested with a voltmeter. I repeated this procedure with a different number of lemons. My hypothesis was not supported since the LED did not light up even though I used up to 5 lemons. Project Number: JPS132 Grade: 6 Title: Perfecting the Pizza Box Abstract: You have probably eaten pizza, but have you considered what factors affect the pizza temperature in the box? In this project, I will be optimizing the common pizza box. I tried to minimize heat transfer by conduction with bubble wrap, fleece, or an extra box, and to minimize heat transfer via radiation with an aluminum foil liner. Preliminary data shows that the fleece and the extra box somewhat help maintain the temperature of the pizza, while aluminum foil and bubble wrap make little difference. Further studies will examine the importance of the original pizza box in maintaining pizza temperature. PRSEF Student Abstracts Page 8 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS133 Grade: 6 Title: Using Robots to Send Alerts on Sudden Cardiac Failures Abstract: Imagine you are at home. Its 3 AM, and you need a glass of water. You go to the kitchen and fill one up. But as you start to take a sip, the glass falls out of your hand and you are overcome with a crushing sensation. No one is near by, and without help, you must die a slow, painful death by heart attack. The goal of my engineering/science project is to help prevent these agonizing deaths. By using sensors,lights, my own programming skills, and testing, I aim to produce a fully functional robot to help alert people nearby to send for help when similar scenarios happen to heart patients. See my project board for more information. Project Number: JPS134 Grade: 6 Title: Craters and Meteorites Abstract: The purpose of my project is to see how the size of a meteorite affects the size of its crater. I became interested because l like meteorites because sometimes I collect rocks outside my house. My procedure was that I measure the different types of items and drop them to get my results. When I tested my types of meteorites, the potato was the biggest with a crater diameter of 5 cm, the apple was the second biggest with a crater diameter of 2.6 cm, the candle was the third biggest with a crater diameter of 2.3, and the marble was the least biggest with a crater diameter of 1 cm. The objects with the larger diameters made bigger craters Project Number: JPS135 Grade: 6 Title: Pop Pop Fizz Fast Abstract: the reason i choose this experiment is that i was intersted in seeing how tempaerture would affect the dissolving rate of an alka seltzer tablet. My objective for this study was to have 3 temperture types and test each temp types and test each temp types 3 times in order to get an average time for each of the temp used. starting with ice water room temp and hot water. the results were as i thought they would be. It was clear very early that the cold water would be the slowest and the hot water would be the fastes. this experiment shows that the dissolving rate for such a product as an alka seltzer tablet can give the consumer the knowledge to get a quicker result for consumption by using warmer temp of water. This will result in the consumer getting relief faster Project Number: JPS136 Grade: 6 Title: Do flames vary in candles based on color and material? Abstract: The project I am planning to do is to figure out if different colored candles or the material change the way the flame burns. Project Number: JPS137 Grade: 6 Title: Soil System Surprise Abstract: Abstract : My project is about the electrical effects of different soil types. I conducted an interesting experiment to prove whether soil could function as an electrical system. In my experiment I simulated electric current by using a battery, two electrodes, soil, and water and recorded the data on the different types of soil conductivity. Through my research I PRSEF Student Abstracts Page 9 Junior – Physical Science (JPS) – 6th Grade expanded my knowledge of soil classification and the surprising applications of this project. Final results to be available at exhibit. Project Number: JPS138 Grade: 6 Title: The Geometry of Goal Scoring Abstract: Abstract The purpose of this experiment is to find out what angle is the best to score from. To conduct this experiment I compared the angle and the chance of scoring. The experimental results were measured by shooting the ball at different angles. The results of the experiment are that both 0 and 35 degree angles are the easiest to score from. The results indicate that the hypothesis should be rejected because a 45 degree angle did not score the most goals. Project Number: JPS139 Grade: 6 Title: Height vs. Stride Abstract: The purpose of this project is to find out if there is a relationship between a person's height and the length of his or her stride. To condict this experiment I compared the height of the person and the length of their stride. The experimental results were measured by having each person take two steps and I measured that as their stride. The results of the experiment show that height does affect the stride of a person. The results indicate that the hypothesis should be accepted because the height did affect the stride. Project Number: JPS140 Grade: 6 Title: The Effects of Temperature on Hydraulic Systems Abstract: My science project is about the temperature of oil in a hydraulic system and how it effects the speed of a machine. I hypothesized that the lowest temperature of oil will cause the machine (log splitter) to operate at the slowest speed. I used oil at the following temperatures: 0 degrees C, 26.6 degrees C, and 53.3 degrees Celsius. Five tests were conducted at each temperature point counting distance and time traveled by the log splitter. My hypothesis was proven correct: the lower temperature of oil caused slower machine operation and the heated oil resulted in faster operation of the log splitter. Project Number: JPS141 Grade: 6 Title: Veggie Power Abstract: Student will create various voltaic cells by using and testing different fruits and vegetables. It is expected that different fruits and vegetables will provide different measures of electricity. PRSEF Student Abstracts Page 10 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS142 Grade: 6 Title: Distance and Speed Abstract: The purpose of this experiment is to see at what diastance a runner achieves the fastest speed. To conduct this experiment i compared speed and distance of the runner The experimental results were measured by having my participant run 50 meters and time them The results of the experiment were that the runner ran faster after the 20 meter marking than before the 20 meter marking. The results indicate that my hypothesis is correct, I accept my hypothesis because the runner ran faster after the 20 meter marking then before the 20 meter marking. Project Number: JPS143 Grade: 6 Title: The Affect of Different Colored Lights on Night Vision Abstract: In my science experiment, I tried to find out whether or not red light affected your night vision less than white light. I was also interested in determining if other colors affect night vision. This was tested by placing colored acetate over a flashlight and then seeing how long it took my eyes to adjust to the dark. It was concluded that red light does not affect night vision as much as other colors. Green, blue, and yellow light were all comparable to white light. Project Number: JPS144 Grade: 6 Title: Does It Pay To Cheat In Baseball? Abstract: The experiment was to determine if it was worth cheating in baseball by using a corked bat. To find out, I took two identicle bats, and I corked the one. I went up to a ballpark, and hit 25 balls with each bat. I put down a stake where each ball landed, and then used a measuring wheel to see how far each ball was hit. I finally realized that both the bats hit exactly the same. Project Number: JPS145 Grade: 6 Title: Parachutes:Descent Time Abstract: The purpose of this project is to see which weighted parachute has the longest descent time. I hypothesized that the largest parachute (the 50cm by 50cm) would have the longest descent time because of the air friction. I cut 4 parachutes of each size (a 20cm by 20cm, a 30cm by 30cm, a 40cm by 40cm, and a 50cm by 50cm.) from plastic garbage bags. I added four washers to bottom of the parachutes, and dropped them in a place where parachutes could fall freely. My 3 tests of each size will determine if my hypothesis is correct. Project Number: JPS146 Grade: 6 Title: It's Electrifying! Abstract: Which material conducts the most static electricity? I hypothesized, that it doesn't matter which material or object you are using, it is the texture that matters. If the texture is rough, more static electricity can be created. If the texture is smooth, there will be a smaller chance of electricity to be created. During my procedure, I had blown up fifty-five balloons and rubbed them on each material to see how many rubs it takes to create at least three strands of my hair to stick to the balloon. In the end of my experiment, my hypothesis was correct. PRSEF Student Abstracts Page 11 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS147 Grade: 6 Title: Weather or Not Abstract: The purpose of my project is to track eight different weather services to see which one had the most accurate prediction. Project Number: JPS148 Grade: 6 Title: Evaporation Station Abstract: The purpose of my project was to determine whether tap water, coca cola, or orange juice would evaporate the fastest. To complete this project, I gathered all materials (graduated cylinders, liquids, table, permanent marker, pencil, and notebook.) I labeled each graduated cylinder, poured the 3 liquids into each graduated cylinder, and recorded data. Each day for 3 weeks I recorded remaining liquid amounts. The tap water evaporated the fastest. Then came the coca cola, then the orange juice. If I were going to do this project again I would test more liquids and use beakers instead of graduated cylinders. My hypothesis was that tap water would evaporate fastest. It was proven correct. Project Number: JPS149 Grade: 6 Title: Does Bow Size Matter? Abstract: I am testing the speed of arrows by shooting them with three types of bows: compound bow, standard bow, and cross bow. I measured speed using a radar gun. An adult performed all shooting tests in an isolated area to prove that the size of the bow doesn’t affect arrow speed. All of the bows are different sizes. I am predicting that the cross bow will shoot the fastest because it is the most high-tech yet the smallest. If so, this will prove that smaller bows can shoot faster than bigger ones. If I were to do this project again, I would try to change the standard bow to a more advanced one. Project Number: JPS150 Grade: 6 Title: Which Wood Burns the Fastest? Abstract: The purpose of my project is to find out which wood burns the fastest out of Cherry, Pear, and Apple. I will cut 4 equal size pieces of each type of wood. I will then find the density of each of the pieces and record it. I will place each piece of wood in a fire pit and ignite it. I will start timing the burn at ignition and stop timing when only ashes are left in the fire pit. Then I will repeat 3 more times with each type of wood. I will use safety measures and have adult supervision as I burn the samples. I will determine if there is a connection between the density of wood and its burning time. Project Number: JPS151 Grade: 6 Title: Does Caffeine Affect Your Energy Level? Abstract: My project tested the effects of caffeine drinks on your energy level. My hypothesis was that a caffeine drink will make someone run faster than a person without a caffeine drink. I timed subjects running a distance without caffeine and then running after consuming a caffeine soda. I repeated for each trial and collected data. My hypothesis PRSEF Student Abstracts Page 12 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS152 Grade: 6 Title: The Hole in the Middle Abstract: In this project, I am trying to find relationships between galaxy properties and the mass of the supermassive black hole (SMBH) at the galaxy's center. The purpose is to make it easier to measure SMBH mass and help understand how galaxies form and what holds them together. In my experiment, I will collect data on galaxy type, size, luminosity, distance, activity, and red shift among other parameters and correlate with SMBH mass. Data collection and analysis are ongoing. Project Number: JPS153 Grade: 6 Title: Ecogyro: The Possibility of Green Flight Abstract: Historical autogyro designs are suitable for further 'green' modifications and autorotation can be accommodated to serve mankind today. Experiment 1 showed that 1) autorotation requires an unobstructive angle of attack, 2) no matter powered or unpowered, the center of gravity must be directly below the rotor axis, 3) successful autogyro flight depends on the correct length/power/rotor diameter ratio. Gyrokites and rubber-powered models have useful characteristics for future Ecogyros: tractor propellers, sensitive rotor blades, and large horizontal stabilizers. Thus, autogyros could successfully use less energy for forward movement and use stored electricity more efficiently. Experiment 2 was an attempt to construct a dual power generation model from Thames and Kosmos Wind Power and Solar Power kits, with a solar panel from a garden light as a back-up battery charger. The system is used to charge batteries: its generator transforms the air conditioner airflow into electricity and it also charges batteries in solar units. The dual powered autogyro that I am calling Ecogyro may harvest energy through a generator hooked up to an autogyro rotor. At the same time, solar power could be used for prerotation and in the beginning of the flight. Project Number: JPS154 Grade: 6 Title: Strength of Rubber Bands Abstract: I wanted to test the strength and elasticity ofrubber bands. I built a 4ft. wooden apparatus containing a suspended hook and recorded the lengths that 1/4” and 1/8”-width rubber bands stretched when supporting different weights, and the weights at which bands broke. I made over 250 measurements. The research confirmed my hypotheses (1) bands stretch in proportion to weight supported, (2) one 1/4”-band compared to two 1/8” (together) stretch similar lengths, and break at similar weights. Bands permanently stretch if weights bounce, and deGrade over time when supporting large weight. This research will help rubber band makers and users. Project Number: JPS155 Grade: 6 Title: Effect of Temperature on Golf Ball Performance Abstract: Environmental factors affect the distance a golf ball travels. Since cold air is denser than warm air and creates drag on the ball, I hypothesize that the golf ball will travel the farthest when hot and the shortest when cold. Analyzing a video, I measured the bounce height of the PRSEF Student Abstracts Page 13 Junior – Physical Science (JPS) – 6th Grade golf balls which were exposed to different temperatures. I found that increasing the temperature of the ball increased the bounce height. As golfers select the appropriate clubs, they can also select balls at appropriate temperatures. Project Number: JPS156 Grade: 6 Title: Keep It Warm Abstract: I did this project because I wanted to know what kind of mug to use to keep liquids warm when I’m traveling in the car. I tested three different kinds of mugs each with a lid and a control set up without a lid. I put 250mL of 75 degrees Celsius water into each mug. I checked the water temperature in the mugs every ten minutes, and I recorded the temperatures in degree Celsius. I performed three tests for each mug. I found out that the stainless steel mug with a lid is the best kind of mug to use. Project Number: JPS157 Grade: 6 Title: Why do Aerobie Rings Fly So Much Farther Than Frisbees? Abstract: In my science experiment, I tried to find out why Aerobie Rings fly so much farther than Frisbees. I did this by researching the four forces of flight and then coming up with a reason for why the rings fly farther. My hypothesis was that the empty space in the Aerobie Ring is what makes it fly farther. I tested my hypothesis by making Frisbees with different sized spaces in the middle and seeing how far they could fly. My experiment's results showed that the Frisbee with the biggest space flew the farthest, and the Frisbee with no space flew the shortest distance. Project Number: JPS158 Grade: 6 Title: Does Temperature Affect the Strength of a Magnet? Abstract: Determine if temperature affects the strength of a magnet. As the temperature decreases the strength of a magnet will decrease. Construct the testing apparatus. Place 5 Neodymium and Samarium Cobalt 30 Gaus magnets in different zip lock bags placing them in a cardboard box separated from one another in the testing chamber for 60min. at 22oC (Control). Randomly select one of the magnets for testing. Place it on the testing apparatus and determine the strength of its magnetic field. Repeat the process for the remaining magnets and at each temperature being tested. Experiment still being conducted. Project Number: JPS159 Grade: 6 Title: Speed Means Power Abstract: My project is about the effects of increasing air pressure on velocity, and increasing velocity on the penetration of BBs fired from an air-rifle into material. The hypothesis was that a BB’s velocity would increase by 152 MPS from one to ten pumps of the air-rifle.I also hypothesized that as the velocity increased, the penetration depth of the BB into a telephone book would increase by 200 pages. I was able to verify my basic hypothesis was correct through testing. I shot the BBs over the chronograph recording each BB’s speed and into telephone books, counting the pages penetrated. PRSEF Student Abstracts Page 14 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS160 Grade: 6 Title: The Need For Speed Abstract: The purpose of this experiment is to find out will running shoes increase speed in a 91 meter dash. To conduct this experiment I compared the time it took for the subject to run 91 meters with and with out running shoes. The experimental results were measured by having my subjects run 91 meters with and without running shoes,while I timed them. The results of this experiment showed that running shoes increase speed in a 91 meter dash. The results indicate that the hypothesis should be accepted because the running shoes did increase speed in a 91 meter dash. Project Number: JPS161 Grade: 6 Title: What Freezes First? Abstract: For my experiment I decided to see what would freeze first. I took 3 separate cups of water. In the first cup, I added 1 4.9 milliliters of salt. In a second cup I added 4.9 milliliters of sugar. the third cup contained only pure water. I put them in the freezer at 0 degrees C. Next, I put strings in each cup.. I then determined when they were frozen by pulling on the strings. I measured the time it took for each to freeze and the type of substance added. My findings were that the pure water froze first, then the sugar water, and last the salt water. Project Number: JPS162 Grade: 6 Title: Chew Bubble Pop Abstract: Does the taste of mint gum or fruit gum help kids in fourth through sixth Grade to help get a better Grade on their math test.My hypothesis is that the mint would help the kids to concentrate more.The hypothesis was correct and I do recommend it to math teachers.I did give the students three of the same type of math test. Project Number: JPS163 Grade: 6 Title: Characterizations of heavy and classical music Abstract: The characteristics of heavy metal and classical music were studied and compared to each other. The beat and power (dB) at 1,000 Hz (20,000 Hz) were measured. Mean beat of classical and heavy metal music was 0.55 and 1.15, respectively. The power was -91.40 dB (108.8 dB) and -65.80 dB (-103.20 dB) for classical and heavy metal music, respectively. It is concluded that the beat and power of heavy metal at 1,000 Hz is faster and higher than those of the classical music. Project Number: JPS164 Grade: 6 Title: Can Caffeine Improve Your Running Speed? Abstract: I did this project because I wanted to find out if caffeine actually could make you run faster. Hypothesis: If you drink caffeine, then you will run faster because caffeine boosts your concentration and focus. Subjects were timed while running a distance after drinking caffeinated PRSEF Student Abstracts Page 15 Junior – Physical Science (JPS) – 6th Grade cola. The same subjects were tested again on a different day after drinking non-caffeinated cola. My hypothesis was supported. Subjects ran faster after drinking caffeinated cola. Project Number: JPS165 Grade: 6 Title: Wee! Abstract: My question was does the size of the marble or surface make a bigger difference in speed? I hypothesized the size of the marble would change the speed. I made slides out of tubing and made a rough surface and smooth one. Then I took three different sized marbles and rolled them down the ramp. After I recorded the time it rolled down the ramp and repeated. After I did all the procedures I saw that my hypothesis was proven wrong. If I were to do this project again I would change what the marbles were made of. Project Number: JPS166 Grade: 6 Title: A Study of EMFs in Cell Phones Abstract: Project Title: A Study of EMFs & Cell Phones The purpose of this project was to compare different types of cell phones and their EMF radiation levels. The hypothesis for the project was that newer phones would emit higher levels of radiation because of the functionality of the phones. The procedure involved measuring both the electric and magnetic fields from 15 different cell phone models in both "transmit" and "recieve" mode. Measurements were made at fixed distances from each cell phone in order to investigate the inverse square law. Measurements were repeated three times and the results were reported as an average of the three trials. Electric and magnetic fields for each model were graphed as a funtion of distance from the phone. Models were statistically compared using a student's t-test. Results indicated that newer phones have lower EMF radiation than older phones. Project Number: JPS167 Grade: 6 Title: Golf Balls Abstract: The purpose of this experiment is to find out if different types of golf balls will travel different distances. To conduct this experiment I compared three different types of golf balls. The experimental results were measured by having my subject hit the different types of golf balls. The results of this experiment showed that the different types of golf balls’ distances varied but little variation. The results indicate that the hypothesis should be rejected because there was little variation in the distances of the golf balls. Project Number: JPS168 Grade: 6 Title: Does the Percent of Salinity Affect Osmosis? Abstract: The purpose of my project is to determine the highest degree of osmosis using different percentages of saline [0.23%, 0.45%, 0.90%]. I used dialysis tubes for my semi permeable membrane. I massed the dialysis tubes with each percent of salinity before and after I put it in the beaker. I poured 500mL of tap water into the beaker and placed the dialysis tube in the beaker. After 5 minutes, the dialysis tube is taken out and massed. I then use a graduated cylinder to see how many milliliters of water was left in the beaker. The highest degree of PRSEF Student Abstracts Page 16 Junior – Physical Science (JPS) – 6th Grade osmosis will be in the dialysis tube that weighs the most and had the biggest change in water volume. I hypothesize that the highest degree of osmosis will be in the highest percentage of saline, which is 0.90%, second in 0.45%, and last in 0.23%. Project Number: JPS169 Grade: 6 Title: Roasting Sunflower Seeds Abstract:The purpose of this experiment is to find out if roasting sunflower seeds at three different time increments affects the color, taste and texture of the seeds. To conduct this experiment, I compared the time increments the seeds were roasted and the color, taste and texture of the seeds. The experimental results were measured by roasting the sunflower seeds at three different time increments and having my human subjects taste them. The results of this experiment showed that some of the seeds had different color, different texture and tasted different and some had the same color, taste and texture. I both accept and reject my hypothesis because some of the seeds had the same color, taste and color and some of the seeds had completely different color, taste and texture. Project Number: JPS170 Grade: 6 Title: MEasuring Enzyme Activity Abstract: Enzymes speed up a wide variety ofchemical reactions, and chemists and biologists use enzymes to do all kinds ofjobs. In this project, pectinase, an enzyme frequently used in the foodindustry, will be used to extract juice from apples. I think it is important to know about howjuice is actually made and what they use to speed it up. To get my results Iwill follow the procedures and study everything about enzymes and Pectinase. From the results I am hoping to learn aboutwhat each step is when a Pectinase breaks down a wall. Project Number: JPS171 Grade: 6 Title: Flex Test Abstract: The purpose of this experiment is to find out if different flexes on different hockey sticks would affect the speed and accuracy of the shot. To conduct this experiment I compared the speed and accuracy and different flexes on the sticks. The experimental results were measured by having two people shoot a puck and I measured the speed with a timer and I put up a target for them to shoot at. The results of the experiment showed that the different flexes did affect the speed and accuracy of the shot. The results indicate that the hypothesis should be accepted because the flexes did affect the speed and accuracy of the shot. Project Number: JPS172 Grade: 6 Title: Do the Muffins Stick or Not? Abstract: I love to bake and cook in the kitchen, but I wondered what non-stick cooking spray works the best? This is a question I often ask myself. I had a hypothesis that if I use vegetable oil, butter, and Pam to coat muffin pans, that Pam will have the best “non-stick” results. I will prepare 3 identical batches of muffin batter and test each product. I will attempt to apply an equal amount of product to each muffin pan. I will record the time that it takes for the baked muffins to fall from the pan when inverted. I think Pam will work the best because I use it the most. PRSEF Student Abstracts Page 17 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS173 Grade: 6 Title: Lemon vs Potato Abstract: The purpose of this experiment is to determine whether a lemon or a potato produces more power. To conduct this experiment i compared a lemon and a potato to see which produces the most power.The experimental results were measured using a voltmeter to find out whether the lemon or the potato can produce more power. The results of the experiment show that a potato produces more power than a lemon. The results ind Project Number: JPS174 Grade: 6 Title: Do Alka-Seltzer Tablets Fizz Faster or Slower in Different Temperatures of Water? Abstract: I did this project to find out how water temperature affects the rate alka-seltzer tablets dissolve in water. My hypothesis was that the hotter the water, the faster the tablet will dissolve because hot water has more energy that cold water. I timed the dissolving rate of alka-seltzer tablets in boiling, hot, room temperature, cold, and ice water. I collected the data. The results supported my hypothesis. The hotter the water the faster the tablet dissolved. Project Number: JPS175 Grade: 6 Title: Whatever Floats My Boats Abstract: The purpose of my experiment was to see if boats made out of the same sized piece of aluminum foil, but made into different shaped boats would hold the same amount of weight. I cut four pieces of foil the same size. Then I folded them to make four different shaped boats . I made barge,hull,oval and round shaped boats . I put the boats, one at a time, into a sink with water and dropped pennies into the boats until they sank. Three trials completed The barge shaped boat held the most weight followed by the oval,hull and round. Project Number: JPS176 Grade: 6 Title: Does Mass Affect Distance Traveled from a Catapult? Abstract: To test Newton’s Second Law of Motion, three balls of different mass (tennis ball, golf ball, and Ping-Pong ball) were launched from a catapult and the distance traveled by each was measured. After building the catapult, each ball was placed in the catapult and launched 20 times. The distance traveled was measured to wherever the ball hit the ground. The average distances traveled were 315 centimeters for the Ping-Pong ball, 381 centimeters for the golf ball, and 414 centimeters for the tennis ball. The distance traveled by the different balls declined with their mass, proving Newton’s Second Law of Motion. Project Number: JPS177 Grade: 6 Title: Melt Down Abstract: The question was "What makes ice melt the fastest?" The problem was trying to figure out which substance melted the ice the fastest. I hypothesized that if I put salt compound on them the ice will melt faster than with the other materials. I chose salt because I know my PRSEF Student Abstracts Page 18 Junior – Physical Science (JPS) – 6th Grade parents and road crews use salt in the winter to treat icy roads. The purpose was to see what object makes the ice melt the fastest. Project Number: JPS178 Grade: 6 Title: Yikes, Balloons Have Gas Abstract: The purpose of my project is to tell how temperature will effect the expansion and contraction of gas. My hypothesis is that temperature will effect the expansion and contraction of gases. I think that balloons will expand in hotter than room temperature air. Also, I think balloons will contract in colder than room temperature air. I will test my hypothesis by putting balloons in hotter than room temperature air, room temperature air, and colder than room temperature air to see which temperature the balloons will expand in and which temperature the balloons will contract in. I will analyze my data by putting all of the results about the expansion and contraction of balloons in the different temperatures into a data table. Project Number: JPS179 Grade: 6 Title: Flying High with Science Abstract: My project is called Flying High for Science. My hypothesis was the light plane would do the best. The reason I did this experiment was I wondered how airplanes being heavy could fly. I built 3 paper airplanes of different paper weight .I marked a spot to throw the paper airplanes and watch there flight patterns My data was the heavy plane went the Shortest, the medium was next in distance and the lightest was the the farthest . I conclude that that the Medium plane did the best in both distance and Straightness. Project Number: JPS180 Grade: 6 Title: Colors of Science Abstract: Abstract The purpose of my expirement was to see if hydrogen peroxide would fade colored cotton more than lemon juice or rubbing alcohol. The procedure was; 1. I got 14 scraps of cotton. 2. Focus on one piece at a time. 3. Put a little of hydrogen peroxide on one piece in my first group. 4. I won't put anything on my second, so I can see how it was affected. 5. Then I will repeat steps 45. My data was pieces of cloth that was stained, and how long they took to dry. My hypothesis was wrong. Project Number: JPS181 Grade: 6 Title: Out of Tune Abstract: my project is about tuning the guitar. how does the weather affect the tuning of the guitar cold or moist? I've concluded that moist affect it more than cold. room's average temp. was 70, cold's average was 34, and moist's average was 71. make 2 wooden guitars. cold would go outside at night, moist would go in bathroom with water on. both for 20 minutes. after record after 20 minutes PRSEF Student Abstracts Page 19 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS182 Grade: 6 Title: The Perfect Chocolate Chip Cookie Abstract: The purpose of this experiment is to determine which cookie sheet produces the “perfect” chocolate chip cookie. To conduct this experiment I compared three different types of cookie sheets with color and texture. The experiment results were measured by having my subject eat cookies from every tray. The results of the experiment showed that the aluminum tray produced the “perfect” chocolate chip cookie. The results indicate that the hypothesis should be accepted because the surfaces did affect the color and texture, and also because the aluminum tray did produce the “perfect” chocolate chip cookie Project Number: JPS183 Grade: 6 Title: The Perfect Grip Abstract: The purpose of this experiment is to find out if the way you hold the football affects the distance of the throw. To conduct this experiment i compared the distance of the throw which were front, middle, and back. The experimental results were measured by having my subjects throw a football with different styles. The results of the expeiment show that the way you hold a football affects the distance. The results indicate that the hypothesis should be acepeted because the way you hold a football does affect the distance. Project Number: JPS184 Grade: 6 Title: Wind Energy is the Best Abstract: Most of the world’s energy comes from oil and coal and that is creating a lot of pollution this experiment studies wind energy. The purpose of this project is to determine which shape of turbine blade shape produces the most energy. I did this by comparing four different shaped blades: rectangular, triangular, trapezoid, and oval at the same speed of wind, same pitch and same distance from the wind source. Measurements of the voltages from the tests showed that the rectangular blades produced more voltage that the other three shapes tested. Project Number: JPS185 Grade: 6 Title: Aqua Rocka! Abstract: Which filter lets water pass through the quickest? My hypothesis is that the panty hose will be the best filter. I am testing a wire mesh filter setup, a nylon panty hose filter set up, and a coffee filter set up. I poured pebble filled water through the setups and I began the timing as soon the first drip of water passed through the filter and into the bottle. I stopped the timer as soon as the stream of water ended and became the first drip after the water has passed through. After running three tests for each filter, I was correct the panty hose allowed water to pass through the quickest. Project Number: JPS186 Grade: 6 Title: Got Strength? Abstract: The purpose of my project is to see if an arch, truss, beam, or suspension bridge is the strongest. My hypothesis was that the truss is the strongest. The procedure for this project is that I made the four bridges out of popsicle sticks, measured their height, weighted them with penny PRSEF Student Abstracts Page 20 Junior – Physical Science (JPS) – 6th Grade rolls, and measured them again. The conclusion of my experiment was that the suspension bridge was the strongest, so my hypothesis was incorrect. Project Number: JPS300 Grade: 6 Title: Corrosion in Your Cup? Abstract: We've been told that drinking soda is bad for our diet. could it also be corroding our tooth enamel? This project will test differnt sodas and observing them daily to note changes. Our hypothosis was that darker sodas containing Phosporic acid would clean the pennies best. This was true. Sodas containing citric acid also did a good job of cleaning while clear sodas didn't. It is our conclusion that all sodas can cause corrosion. Project Number: JPS301 Grade: 6 Title: Does a Jet Hull Shape Effect Fuel Efficiency? Abstract: The purpose of this experiment was to see if we could reduce the fuel used in regular jets/airplanes. Shashank's opinion was that the F-16 Fighting Falcon (his plane) would be the most aerodynamic jet in the experiment. Shaunak's opinion was that the Black Hawk (his plane) would be the most aerodynamic jet in the competition. First we build our jets hull shapes. Then we will make two holes on each side of a plastic box. After that, we will fill up the box with water with blue food coloring. Finally we will put our jets hull shapes into the box and we will put a small fan on one side of the hole and a paper on the other side. Then, we will time long it takes from the fans wind to travel from one side of the box to the other side. We will record the times in the data book. Project Number: JPS302 Grade: 6 Title: How can a flashlight power a solar panel from different distances? Abstract: Abstract: How can a flashlight power a solar panel from different distances? We are going to study the effect on solar panels and light. We think that the closer the light to the solar panels, they brighter and longer the light will shine. We are testing from different distances. We will take a flashlight, aim it at the panel and observe the effect on the circuit. Project Number: JPS303 Grade: 6 Title: How can different types of lights affect water temperature over time? Abstract: Abstract Title: How can different types of lights affect water temperature over time? We decided to study the temperature of water under different types of lights. We were inspired by the NASA Now “Feel the Heat” classroom activity. Our project will determine what different types of lights produce heat on water overtime. We put an LED light, lamp light, and sunlight over three glass beakers of water. Then we recorded the temperature after one minute, five minutes, and ten minutes. This experiment is still in process and further results will be studied PRSEF Student Abstracts Page 21 Junior – Physical Science (JPS) – 6th Grade Project Number: JPS304 Grade: 6 Title: Insulating Capabilities of Leather, Cotton, and Wool Abstract: Advertisers say their coat will keep us warm, but which common material is the warmest? Should we choose a wool, cotton, or leather coat to keep out the cold when we play outside? We tested our choice of wool by wrapping soda cans filled with hot water in wool, cotton, and leather and measured the heat loss. Our final results will be available at our display the day of the fair. Project Number: JPS305 Grade: 6 Title: Vroom, Vroom Goes the Car Abstract: This experiment was to determine which size (length and width) of a latex rubber band would power a model car to go the farthest distance. Using the same surface and the same model car, we tested several sized rubber bands. The distance was recorded and compared. We concluded that the rubber band that made the model car go the farthest was not the thickest, but the longest. PRSEF Student Abstracts Page 22 Junior – Life Science (JLS) – 6th Grade Project Number: JLS100 Grade: 6 Title: Does Age Affect Vocal Range? Abstract: My project was on does age effect how high and low you can sing? In my hypothesis I thought I men sing higher than women then they will have a larger vocal range. My research taught me that usually men have a wider vocal range. As I did my experiment I observed that women were singing higher then men. My conclusion stats that my hypothesis was not proven and men had less of a vocal range than women. Project Number: JLS101 Grade: 6 Title: There is Fungus Among Us Abstract: My question is “Does the type of bread affect the rate of mold growth?” I did this experiment to see whether or not the type of bread affects the rate of mold growth. I bought white, whole wheat, rye, and sour dough bread from Bread Works. I laid them on a table and recorded changes for 10 days. White molded fastest, and sour dough bread molded the slowest. I believe sour dough molded slowest because of its high acidity levels. This experiment gave me an idea for a new experiment. I can test different kinds of natural preservatives. Project Number: JLS102 Grade: 6 Title: Flowers Are dying to Change Color Abstract: The purpose of my experiment was to see if dye would change the color of carnations fast. My procedure was to place carnations in a controlled amount of water and dye to see how quickly the color absorbed. I checked them at the same time daily. I kept some flowers in the light and dark. My data was proven by pictures of the dye in the flowers. My conclusion is that white carnations are hard to find, yet the best flower to use for this experiment and found that the flowers kept in the dark changed more than light. Project Number: JLS103 Grade: 6 Title: What Do Different Ingredients Do? Abstract: When you are following a recipe, do you ever wonder why certain ingredients keep showing up time after time,(baking powder in breads)? Do you notice that certain ingredients tend to occur in a particular ratio to one another,(amount of shortening and sugar, amount or number of eggs and flour)? What happens if you use more or less than it says in a recipe? What happens if you change the ratio of two ingredients? What ingredients can act as substitutes for other ingredients? There are many possibilities you can try for all the ingredients in a recipe. Like maple syrup and honey can be a substitute for sugar. Project Number: JLS104 Grade: 6 Title: Where Should I Plant It? Abstract: The purpose of my experiment was to determine if fallen leaves from trees affect plant germination and growth. I collected tree leaves. I dried the leaves. I chopped the leaves with a blender. I put soil into cups with the leaves. I added a seed and water to the cup and exposed it to a growth lamp. I recorded the date. When the plant inside the cup germinated, I recorded the PRSEF Student Abstracts Page 23 Junior – Life Science (JLS) – 6th Grade date. I measured how tall the plants grew over a period of days. I drew conclusions from this procedure. Results will be available at the fair. Project Number: JLS105 Grade: 6 Title: Do plants have a sweet tooth? Abstract: This experiment sought to determine how different types of plant food affect plant growth. I planted bean seeds in a germination container to speed up the germination process. I fed them approximately ten ml. of water of water solution a day unless the soil was still damp. 18 of the plants received regular water, eighteen received a mixture of water and sucrose, and eighteen received a mixture of water and glucose. I thought that the plants receiving water only would grow the fastest, the glucose water the second fastest, and the sucrose water the slowest. The results confirmed my hypothesis. Project Number: JLS106 Grade: 6 Title: Nature vs. Nurture Abstract: The purpose of this is experiment is to find out if a kitten that has been nurtured would be more family friendly than a kitten's nature. To conduct this experiment I compared a kitten that has been nurtured and a kitten that is initially left to its own adaptations. The experimental results were measured by observing kitten A(nature) and playing with kitten B(nurture). The results of this experiment showed that a nurtured kitten is more family friendly than a kitten's nature. The results indicate that the hypothesis should be accepted because a kitten that has been handled(nurtured) is more family friendly than a kitten's nature. Project Number: JLS107 Grade: 6 Title: Voice Range Abstract: The purpose of this experiment is to find out if experienced singers ages 7-12 have a larger voice range than inexperienced singers. To conduct this experiment I compared experienced singers and inexperienced singers voice range. The experimental results were measured by having my subjects sing the scale. The results of the experiment showed experienced singers had a larger voice range. The results of the experiment indicate that the hypothesis should be accepted because the experienced singers could sing more vocal notes than inexperienced singers. Project Number: JLS108 Grade: 6 Title: The Alternative Is Ethanol Abstract: Alternative fuel source’s objectives are to emit less harmful and less polluted air into the atmosphere and to be more efficient. One of the tested alternatives is ethanol fuel. The purpose of this experiment is to determine the amount and nature of alcohol fuel produced through fermenting and distilling compost (organic substances). I hypothesized that there will be a small amount of alcohol fuel that can be produced through fermenting and distilling compost. In my experiment, I collected, fermented, and distilled organic compost to produce alcohol fuel. The collected fuel was tested to determine its nature. The results will be available on the Fair Day at my exhibit. PRSEF Student Abstracts Page 24 Junior – Life Science (JLS) – 6th Grade Project Number: JLS110 Grade: 6 Title: can the nose smell but how about taste? Abstract: The purpose of this experiment is determine if the sense of smell affects how we taste. I became interested in this topic because at home when my mom cooks something I don’t like I can already tell if I don’t like it just by how it smells. I first picked some foods that science buddies offered and then I had my volunteers taste the different types of foods with and without nose plugs. The turnout of of my experiment worked perfectly. My volunteers tasted the foods better when they didn’t have nose plugs in. In conclusion the nose can smell and taste. Project Number: JLS111 Grade: 6 Title: Memory Like an Elefont Abstract: There have been a number of experiments showing that the font style affects memorization of written words. However, there have been no experiments determining whether or not the font style affects the memorization of random numbers by middle school aged students. 20 middle school students, 10 boys and 10 girls, were asked to remember five random number sequences typed in five different font styles for 60 seconds. They were then asked to recall the numbers in order. The results showed that the fonts did not affect the recall of the numbers. Project Number: JLS112 Grade: 6 Title: Long Jump Expert Abstract: The purpose of my project is to see if the distance you run effects the distance of the jump. My procedures are first I will measure the distance that the runner will jump. Then, I will signal the runner to run. Finally, after they have jumped I will record it all in my data book. My data states that the further you run, the further you will jump. In conclusion the further the runner ran the further the jump was. Project Number: JLS113 Grade: 6 Title: Caffeine and Typing Speed Abstract: The purpose of my project is to determine if caffeine affects typing speed. For this project I needed 10 subjects to perform the typing tests. My independent variables were: Mt. Dew, water, Carmel Macchiato. First, I tested the average typing speed of each subject with no caffeine in their bodies 3 times. Next, I gave them 354 mL of water, and retested them 3 times. Then, I gave them 354 mL of Mt. Dew and retested them 3 times. On day 2, I finally gave them 354 mL of a Carmel macchiato and retested them 3 times. My results were that the majority of my subjects had their highest typing rate with the Carmel macchiato in their system. The other subjects had mixed results. PRSEF Student Abstracts Page 25 Junior – Life Science (JLS) – 6th Grade Project Number: JLS114 Grade: 6 Title: Sound Waves Abstract: My project question was does sound effect coordination. I took my test subjects into a quite room, then I had them do two hand-eye coordination tests. One time in a quiet environment and the next time in a noisy environment. After i finished my experiment I compared my results. On threading a needle they both had the same results in a quite environment and a noisy environment. For getting a golf ball in a cup I realized it was better to do this in a quite environment. Project Number: JLS115 Grade: 6 Title: The Memory Challenge Abstract: The purpose of this experiment is to find out which sense between vision and hearing, is best for remembering a sequence of numbers. To conduct this experiment I compared vision and hearing to determine which sense people used the most to remember a sequence of numbers. The experimental results were measured by having my subjects look at a sequence of numbers and read numbers and then they recited them. The results of the experiment showed that vision is better than hearing. The results indicate that my hypothesis should be rejected because the subjects remembered more numbers by hearing. Project Number: JLS116 Grade: 6 Title: Acid Rain Abstract: Have you ever wondered why old structures are discolored and dilapidated? This project looks at which materials are affected by acid rain. The following items were placed in lemon juice, vinegar, and distilled water: Penny (copper), nail (zinc), roof shingle, chalk (calcium carbonate), and plastic. My hypothesis was that if acid rain falls at a reasonable pace, then chalk will dissolve in several days. The experimental results supported my hypothesis because the chalk that was soaked in acids became soggy and wore away quickly. The experiment also showed that other materials such as plastic were not impacted by the acids. Project Number: JLS117 Grade: 6 Title: Are You Smarter Than a Sixth Grader Abstract: My project is on why some people are good at subjects they like. The purpose of my project was to figure out all of the methods for getting good Grades. My hypothesis was that they try harder. First, I got ten classmates and asked them their favorite subjects. Next, I asked them why they are good at the subject they picked. With that, I tested all the methods to see if they all worked. During the project, I noticed that there are a lot of ways to get good Grades. My project could give some ways of getting better grades. Project Number: JLS118 Grade: 6 Title: Food and Color Interactions Abstract: "Does the color of food and drinks affect whether or not kids ages 5-8 enjoy them?" I had each child rank the colors red, orange, yellow, green, blue, purple, and brown. I then took PRSEF Student Abstracts Page 26 Junior – Life Science (JLS) – 6th Grade rice crispy treats, vanilla pudding, milk, and water in the colors that I had them rank and they ate them. My results showed that their favorite color choices matched their favorite food color choices and that their least favorite colors didn’t match their least favorite food color choices. My conclusion is the color of food and drinks does affect how we enjoy them. Project Number: JLS119 Grade: 6 Title: Distracting Distractors Abstract: The purpose of this experiment is to find out does the number of distractors affect the ability of the observer of to find the visual taget. To conduct this experiment I compared the number of distractors and how long ot took to find the visual target. The experiment results were measured by having my subject find a visual target with multiple distractors. The results of the experiment showed that the distractors affected the abilty to find the visual target. The results indicate that the hypothesis should be accepted, because the distractors had an affect of the ability to find the visual target. Project Number: JLS120 Grade: 6 Title: The Power of Suggestion Abstract: In this project, I hope to help the whole world understand to a greater extent the preteen mind. I have given a brief quiz to a learning group of varied levels of skill, some with answers marked to asses each student's trust in an unknown source. This could help in the field of child psychology, and see how likely it is for teens to accept drugs or other harmful substances. Project Number: JLS121 Grade: 6 Title: Drought resistant fertilizer Abstract: In my experiment, I tested which fertilizer rich in a particular ingredient will help plants sustain drought the best. My purpose of this experiment was to improve plant growth in drought climates, and this way plants can be grown in places that get less rain. Nitrogen, Phosphorus, Potassium, Calcium, and Magnesium are the ingredients in the fertilizer which were tested. The experiment had 5 sets of plants, and each set was exposed to one ingredient. The plants were watered once a week to simulate drought conditions, and were measured every day. Project Number: JLS122 Grade: 6 Title: The Power of Cute Abstract: The purpose of my experiment was to find if cute pictures affect visual recall and motor skills. I believed that the pictures would elicit an improvement in both tests. I tested this by showing half my subjects cute pictures; the other half saw none. All subjects had one minute to to view neutral pictures, and three minutes to recall as many as possible. Half the subjects were shown the cute pictures again, and all subjects played a motor skills game. My hypothesis was partially correct: subjects shown cute pictures saw an improvement in motor skills, but not in visual recall. PRSEF Student Abstracts Page 27 Junior – Life Science (JLS) – 6th Grade Project Number: JLS123 Grade: 6 Title: Girls Just Wanna Have Sun (and Worms) Abstract: The purpose of my experiment is to see if earthworms in plain topsoil improve plant growth. I planted “Early Girl” tomato seeds in two planters . One planter contained earthworms, the other did not. I made observations and identified my planters as P1- without worms and P2with worms. Grow lights were used and the plants were watered as needed. I measured my plants weekly. The tomato plants with worms measured the tallest plants . The planter without worms was shorter. The average height for P2 is 5.5cm for P1 it is 4.5cm. Earthworms may have contributed to their growth. Project Number: JLS124 Grade: 6 Title: Oil Vs Plants Abstract: The purpose of the experiment is to determine how shallow water plants are affected by oil. I used three beakers and organized them from A to C. I put different amounts of oil in beakers B and C, 30 mL in B and 60 mL in C, And left them alone 3 weeks. Data I have collected includes plant growth and leaves turning from green to brown. The plant from beaker A grew the most. The plant from beaker C didn't grow. But the plant in beaker B shrunk. I have concluded that oil affect's the growth of sea plants. Project Number: JLS125 Grade: 6 Title: Nature's Candy Abstract: The purpose of this experiment is to find out which fruit has the most sugar. To conduct this experiment I compared the amount of sugar in four fruits. The experiment results were measured by using a sugar testing kit to determine how much sugar is in the fruit. The results of this experiment show that oranges have the most sugar and apples have the least of sugar. The results indicate that the hypothesis should be accepted because oranges had the most sugar. Project Number: JLS126 Grade: 6 Title: Can Potatoes See? Abstract: My experiment was to see if the number of sprouts would correspond with the number of eyes on the potato/potato pieces. I placed whole potatoes/potato pieces with 0-4 eyes into brown paper bags storing them at 9° and 18° Celsius for two weeks. The results showed that potatoes stored at either temperature did not sprout. I expected sprouting at 18° Celsius. I can only conclude that potatoes will not sprout at 9° Celsius. If I experimented again, I would increase the temperature of the control group and wash the potatoes before beginning, in case there is any sprout inhibitor applied. Project Number: JLS127 Grade: 6 Title: The Science Behind the Left and Right Brain Abstract: I wanted to test the theory that, although our society is considered "left brained," there are still "right brained" thinkers among us. My hypothesis is that there are right brained people in our world. I let each of my 17 participants take a survey that would determine if they are left, PRSEF Student Abstracts Page 28 Junior – Life Science (JLS) – 6th Grade right, or golden brained. The results indicated that 8 were left, 6 were right, and 3 were golden brained. My hypothesis was supported in that even though we live in a left-brained society, there are still many right brained people. Project Number: JLS128 Grade: 6 Title: Maze of Music Abstract: The reason I did my experiment is because I was looking for an experiment for school, and my mom told me about this experiment and it interests me the most. The mouse started the maze when the music started. There is one maze that the mouse went through. I did 10 tests for each of the 5 types of music. Once the mouse completed the maze, I would stop the music and record the amount of time it took the mouse. The averages were: jazz, 6:32 minutes; country, 2:28 minutes, rap, 4:2 minutes; classical, 3:32 minutes; standard (no music) 5:03 minutes. My conclusion is that country music helped the mouse complete the maze the fastest. Project Number: JLS129 Grade: 6 Title: The Chocolate that Melts the Fastest Abstract: Project Title: The Chocolate that Melts the Fastest This experiment was to find out which chocolate melts faster; milk, dark, or white. My hpothesis was that if the dark chocolate was melted, then it would melt faster than white or milk chocolate. The procedure involved putting each chocolate in a separate pan and placing it over a pan of simmering water. I timed how long it took for the chocolate to melt into a liquid and recorded the data in the data book. The analysis included the amouint of time it took for each chocolate to melt (change from a solid to a liquid). Results indicated the dark chocolate melted fater than the white or milk. Project Number: JLS130 Grade: 6 Title: Effect of Different Liquids on Germination Abstract: The purpose of my project is to determine how different liquids will affect the growth time on the basil oil plant. I became interested because I like to try new things and when I saw this topic I thought it would be interesting to try something new. I planted basil oil seeds and watered them with different liquids to see which one will grow the fastest. I thought that the water was going to make them germinate the fastest because when you plant seeds you usually would use water, and the water would have the seeds sprouting in no more than 5 days. Project Number: JLS131 Grade: 6 Title: What Would You Eat? Abstract: The purpose of this experiment was to determine if people would choose to eat blue or green pudding as opposed to eating erred pudding. To conduct this experiment I will have five people choose to eat a blue,red,or green color pudding. The experimental results were measured by comparing people's decision to eat it and the colored pudding pudding that was tinted blue,red,and green. The results indicate that the hypothesis should be rejected, because people choose the red colored pudding over the blue and green color pudding. PRSEF Student Abstracts Page 29 Junior – Life Science (JLS) – 6th Grade Project Number: JLS132 Grade: 6 Title: Effects of Caffiene on Plant Growth Abstract: The purpose of the study is to determine if caffiene has a positive or negative growing effect on sunflower seeds. Proper growing conditions, and different distributions of caffiene will be added to collect data points. Project Number: JLS133 Grade: 6 Title: Green Thumbs Abstract: My problem statement is: Will microwaved, boiled, or tap water contribute to string bean plants’ height. My hypothesis is that the boiled water will make them grow taller. The purpose of my project is to see if microwave radiation will make the plants die. If they do die, then does that mean that microwaves are dangerous to humans? I planted twelve bean plants and watered four of them with tap water, four with boiled water, and four with microwaved water. I measured the height of all plants at regular intervals. I will determine if my hypothesis was proven correct when I have completed my experiment. Project Number: JLS134 Grade: 6 Title: Do Fears Change With Age? Abstract: My project involves the science of what people fear and the behavioral science behind it. My hypothesis was that if someone is afraid of unconventional things when they are young, as they grow older, chances are that they will fear more relevant things because they are more mature. I used surveys (different age groups) for my data and results. I found that fears do change with age, and some stay the same so my hypothesis was supported. This can be useful to statisticians, sociologists, and psychologists. Project Number: JLS135 Grade: 6 Title: A Mouse's Memory Abstract: The purpose of this expirement was to find out if a mouse had memeory to complete a maze and if it did, how long was its memory of the maze. To conduct this expirement I compared the time the the mouse took to complete the mazeand if the mouse remembered the maze. The expiremental results were measured by how much time it took for the mouse to go through the maze. The results of this expirement showed that the mouse did go through the maze faster on its seventh trial. The results indacate that the hypothesis should be accepted because the mouse's times got faster on the seventh trial. Project Number: JLS136 Grade: 6 Title: Density of Cookies with Different Sweeteners Abstract: Project Title: Density of Cookies with Different Sweetners. This experiment is to determine which sweetener; granulated sugar, brown sugar, or molasses makes a denser cookie. My hypothesis is molasses will make the cookie denser because molasses is thicker than granulated or brown sugar. I will test my hypothesis by making three batches of PRSEF Student Abstracts Page 30 Junior – Life Science (JLS) – 6th Grade cookies each with a different sweetener. For the data analysis, I will measure the density in two ways; by its mass on an arm balance scale and measuring the volume (lenght, width, and height)of each cookie. Results to be determined. Project Number: JLS137 Grade: 6 Title: The Best Way to Make A Foul Shot for Pre-Teen Girls Abstract: To find out the best way to make a foul shot for pre-teen girls. Stand at the foul line shoot three granny shots,then again shoot three set shots without jumping, then for the last time shoot three jump shots with out jumping over the line. They did this on three different events. The girls made 18 granny shots in all 15 set shots in all and 24 jump shots in all. In conclusion my hypothesis was correct the jump. shot was the best for pre-teen girls Project Number: JLS138 Grade: 6 Title: What's in a Face? Are Composite Faces More Attractive than Real Faces? Abstract: I did this project because I wanted to know if composite faces are more attractive than real faces. My hypothesis is that if someone sees a picture of a composite face vs. a real face they will pick the real face because it is natural beauty. I showed boys and girls images of composite faces and real faces and had them select the more attractive image. I recorded the data and found out that my hypothesis was supported because the real faces were more attractive. Project Number: JLS139 Grade: 6 Title: Stubborn Stains Abstract: The purpose of this experiment is to investigate which liquid; Pepsi, coffee, red wine, stains enamel on an egg the most. To conduct this experiment I compared the liquids and how much each liquid stained the egg enamel. The experimental results were measured by placing each egg in the three liquids for five, ten, and fifteen minutes. The results of the experiment shows that red wine had the most effect on the eggshell enamel the most. The results indicate that the hypothesis should be accepted, because the red wine stained the enamel on the eg the most because the color of the red wine had the most effect on the color of the eggshell originally. Project Number: JLS140 Grade: 6 Title: Guppie growth Abstract: From birth, guppies grow gradually until they reach adult dimensions (about 3 months). The rate at which they grow is affected by their environment, including with water cleanliness and temperature, as well as food availability. It is unclear whether availability of ambient light is a factor. I hypothesized that fish subjected to continuous darkness would experience a slower growth rate, resulting in smaller adult dimensions (length and weight) than fish grown under normal ambient light conditions. PRSEF Student Abstracts Page 31 Junior – Life Science (JLS) – 6th Grade Project Number: JLS141 Grade: 6 Title: Wake Up Abstract: My science project explored dreams. Through this exploration my goal is to prove that girls dream more than boys. In this exploration I created a survey. This survey included 6 categories. There were 4 participants in each category which included 2 boys and 2 girls. The first step of my experiment was to create a questionnaire. Second I handpicked my survey group. Last I tallied the boys and girls to determine whether they dreamed or not. I concluded that girls dream more than boys. Project Number: JLS142 Grade: 6 Title: Flipping for Science Abstract: Athletes are encouraged to warm up and stretch before executing any skill, but does stretching really afect the outcome of the skill? This project looks at five gymnasts who complete a flip before stretching and a flip after stretching. The gymnast were videotaped at 9:00A.M before stretching. The gymnast wre also, video taped at 9:30 A.M after stretching. My hypothesis was that stretching would allow the gymnast to do a better flip than not stretching prior to doing a flip. The experimental results supported my hypothesis by showing that four out of five gymnasts performed the skill better after stretching. Project Number: JLS143 Grade: 6 Title: Can You Guess That Taste????? Abstract: The purpose of my experiment was to find out who had a better sense of taste boys or girls. In my experiment I first took one boy and one girl from fourth. Then I had them taste and guess three different flavors of flavored water. The flavors were grape, orange and lemon. After they tasted the flavors I put down in my data book, if they correctly guessed the flavor in the cup. In the end I saw that if people couldn’t correctly guess the flavor in the cup in a short amount of time they guessed a random flavor. Project Number: JLS144 Grade: 6 Title: Do Plants Love Clay or Soil Abstract: When I started my project I made a list of what I should do for my project. I collected all of my data in a notebook to keep track of how tall they grew. I watered them for 12 days. At first the plant in the soil grew faster. Then the clay started to catch up. The plant in the clay won. I did not no this because I thought the soil had more mineral and nutrients in it. Project Number: JLS145 Grade: 6 Title: Sight vs. Taste Abstract: The purpose of this project is to see if sight affects taste. To conduct this experiment I compared how sight affected taste. The eperimental results were measured by having the subjects try Jell-O that was dyed a different color than is usally associated with a natural flavor. The results indicated that the hypothesis should be partially accepted because of other influences that may have been present during the experiment. PRSEF Student Abstracts Page 32 Junior – Life Science (JLS) – 6th Grade Project Number: JLS146 Grade: 6 Title: Blue vs Red vs Yellow Abstract: The purpose of this project is to see if color improves memory for sets of numbers. Some other organizations and universities have tested this in the past and they have gotten results. I think red could improve memory because, it might make letters look like it is popping up. I tested this by first showing a person a set of numbers then asking the numbers every 1 minute until the 5th minute. Based on the results, there was a difference, red improved memory the best, but blue did not. Project Number: JLS147 Grade: 6 Title: What does the Brain Process Faster: Words, Shapes, or Colors? Abstract: My project was designed to determine what the brain processes first; colors, shapes, or words. My hypothesis is, "If children and adults are presented with sets of colors, shapes, and words, the children and adults would choose colors because colors are easier to process." I used notecards with color, words, and shapes. Participants were asked to identify what was on the card while being timed. My hypothesis was supported in that they processed colors faster than shapes or words. Project Number: JLS148 Grade: 6 Title: What Bird Seed Do Birds Prefer? Abstract: My project tested bird seed preference with millet, sunflower, safflower, or cracked corn. My hypothesis was that given a choice, birds will select sunflower because they are familiar with that type of seed. I gathered bird seed materials and set up outside. I observed the eating habits of the birds for 15 minutes and repeated. My hypothesis was supported since the birds chose the sunflower seeds over all the other types. Using this data, we can provide food the birds prefer. Project Number: JLS149 Grade: 6 Title: To eat or not to eat? That is the question. Abstract: I asked myself this question: Is the best environment for keeping bread fresh the refrigerator, bread box, or countertop? I tested this so people know in which environment to store their bread. I first checked to make sure that the temperatures were suitable. I packaged six slices of bread individually and placed two in each environment. I checked them every week. I learned that the refrigerator was the best method. The bread box was second, the countertop third, supporting my hypothesis. Future experiments include testing a metal bread box and using homemade bread to eliminate time sitting on store shelves. Project Number: JLS150 Grade: 6 Title: Does Mental Rehearsal Improve Free Throw Shooting in Basketball? Abstract: My project tested whether mental rehearsal improves free throw shooting in basketball. My hypothesis is that mental practice will improve free throw shooting performance. PRSEF Student Abstracts Page 33 Junior – Life Science (JLS) – 6th Grade I had my subjects shoot 10 shots with no rehearsal to establish a baseline. Some then shot 10 shots after mental rehearsal and the control group shot without rehearsal. Multiple trials were conducted and the data was averaged to see if those who mentally rehearsed made more shots. Those who mentally rehearsed had a better shooting average than those who did not so my hypothesis was supported. Project Number: JLS151 Grade: 6 Title: The Garbage Plants Abstract: My experiment was to show plants can grow in other soils. I planted green bean, tomato, lettuce, and watermelon seeds in six different soils. The soil types were a “control”, “sand”,” garbage”,” paper”, “mixed garbage” and “vegetable.” Green beans and lettuce plants are growing in the “paper” soil. Watermelon and tomato plants are growing in the “sand” soil. Lettuce and tomato plants are growing in the “control” soil. My experiment is ongoing, but I think it has been successful in showing that plants can grow in other soil types besides dirt. Project Number: JLS300 Grade: 6 Title: Acorns and Fungi Abstract: We conducted our science fair experiment to investigate the amount of a yard waste product, acorns, needed to produce the greatest mass of Pleurotus osreatus otherwise known as oyster mushrooms. Using .11, .23, and .34 kg of acorns (nitrogen substrate) mixed with straw (carbon substrate), we hypothesized that .34 kg would grow the greatest mass of mushrooms. Our preliminary data chart showed that after 3 months, the bags containing .34 kg of acorns averaged 65.0% visible mycelium, compared with 49.0% (.23kg), 25.6% (.11kg), and 59.0% (control group). We conclude, the more acorns used grows the greatest mass of mushrooms. Project Number: JLS301 Grade: 6 Title: Creek Connections Abstract: The purpose was to find out if Squaw Run will be a healthier waterway than Pine Creek. Our procedure was to go to Squaw Run and look for macro invertebrates and test for water chemistry. At Pine Creek, we found no group 1, 100s of group 2, and 10 group 3. The pH was 6 and the temperature was 15c. At Squaw Run, we found 6 group 1, 5 group 3, and 3 group 3. The pH was 7 and the temperature was 11c. Because of these findings, we conclude Squaw Run is healthier than Pine Creek. Project Number: JLS302 Grade: 6 Title: CRITTER CATCH Abstract: The purpose of our experiment was to find out if there was more aquatic life or evidence of aquatic life in lentic or lotic water. Two creeks, Salamander Park and Squaw Run Valley Park, were explored. The temperature, pH, and total dissolved solids (TDS) were observed for both creeks and were found to relate to the observed life count. Graphical representation of our data was used to interpret the correlation between various factors. Based on what we found, tested, and recorded, Squaw Run Valley Park was healthier for survival of aquatic life forms. PRSEF Student Abstracts Page 34 Junior – Life Science (JLS) – 6th Grade Project Number: JLS303 Grade: 6 Title: Decaying Cafe to Oyster Mushrooms Abstract: The purpose of our science fair experiment was to investigate the amount of coffee grounds needed to grow the greatest mass of Pleurotus osreatus (oyster mushrooms). Using .11, .23, and .34 kg of coffee grounds (nitrogen) mixed with straw (carbon), we predicted that .34 kg would grow the greatest mass of mushrooms. Our preliminary data showed that after 61 days, the bags containing .34 kg of coffee grounds contained an average of 53% visible mycelium, compared with 42% (.23kg), 40% (.11kg), and 23% (control group). We conclude that the more coffee grounds used grows the greatest mass of mushrooms. Project Number: JLS304 Grade: 6 Title: Expedition Creek Abstract: The purpose of our experiment was to see if the pH, TDS, and DO of Nine-Mile Run Creek and Falls Ravine Creek were suitable for aquatic life. Our procedure included gathering water samples from both creeks, hunting for macro-invertibrate using a kick-net, looking for amphibians, testing pH on site and testing pH, TDS, and DO at school using the samples collected on location. We found one class one macro-invertebrate, four class two and about 26 class three. We found two Northern Dusky Salamanders. The pH, TDS, and DO levels were satisfactory. Overall, both creeks were somewhat suitable for aquatic life. Project Number: JLS305 Grade: 6 Title: Growing Oyster Fungi on Floral Waste Abstract: For the science fair, we are growing oyster mushrooms (Pleurotus ostreatus). The purpose of this is to find an amount of waste nitrogen substrate (floral waste) mixed with carbon substrate (straw) that will produce the most oyster mushrooms. We predict .33 kilograms of floral waste will produce the most oyster mushrooms, in comparison to .11 and .22 kilograms. Our control was void of floral waste and only had straw.The procedure used during this experiment is to observe the mushrooms and record the percentage of mycelium present. The results we've collected showed that the control has produced on average 47% mycelium which is the greatest amount overall. Therefore we can conclude that the floral waste did not promote oyster mushroom growth as much as we predicted. Presently .11 kg = 27%, .22 kg = 33% and .33 kg = 43% average mycelium growth. Project Number: JLS306 Grade: 6 Title: Macro-Inverts at Squaw Run Crk. Abstract: The purpose of our project was to determine the health of Squaw Run Creek based on the presence of Class 1 macro-invertebrates. We expected the creek to be too polluted to support Class 1 macro-invertebrates. Class 1 macro-invertebrates are sensitive to pollution and if present indicate good water quality. We tested for pH, temperature, and dissolved oxygen levels. We recorded the presence of macro-invertebrates. The water temperature was 15° Celsius, the pH was 6.0, and dissolved oxygen level was 10 mg/l. We found both Class 1 and Class 2 macroinvertebrates. We concluded that Squaw Run Creek had excellent water quality. PRSEF Student Abstracts Page 35 Junior – Life Science (JLS) – 6th Grade Project Number: JLS307 Grade: 6 Title: Tri-Creek Investigation Abstract: We tested creeks to see if a neutral vs. high or low pH affected the number and diversity of creatures in the stream. Our procedure was to go to the stream, test the pH, and then search for life in the stream. At the creeks with a pH of two we found two creatures and had a diversity of two. At the more neutral pH streams we found around twenty creatures and about a diversity of six. Our conclusion was that the neutral pH encouraged the number of creatures and the diversity of creatures. High and low pH did not. Project Number: JLS308 Grade: 6 Title: Tri-Investigation Abstract: The objective of our experiment was to discover if Squaw Run Creek was cleaner upstream and how that affected the type of wildlife and water chemistry we found. At Squaw Run Creek, we tested for pH, dissolved oxygen, total dissolved solids and the temperature of the creek. The main tests included pH which measured a level of 6.5 and the temperature at 15 degrees CentiGrade. We found a rainbow trout and a riffle beetle in the creek both upstream. In conclusion, the creek was healthy upstream because we found a healthy water chemistry and pollution intolerant organisms. Project Number: JLS309 Grade: 6 Title: What Do You Feed Your Plants? Abstract: Eight angel plants were fed eight different liquids to see how they impacted plant health. The liquids used were water, Gatorade, coffee, Coke, apple juice, mouth wash, V8, and lemonade. The plants were given 1/4 cup of liquid every other day. The health of the plants fed water, Gatorade, and lemonade stayed the same. With coffee the plant's growth improved. Mouthwash killed the plant quickly. Coke, apple juice, and V8 all weakened the plants. We did this project because we thought it would be interesting and fun to do and to gather infromation on what different liquids do to house plants. PRSEF Student Abstracts Page 36 Junior – Consumer Science (JCS) – 6th Grade Project Number: JCS100 Grade: 6 Title: Homemade Markers Abstract: The purpose of my project is to determine if you can cut down on waste by creating reusable markers. I became interested because I like color and since markers are used for coloring I picked this topic. I used different type of materials to make markers and see if they are comparable to Crayola markers. My markers did good at first they wrote good and everything. The markings were not like a pencil they were kind of like pain Project Number: JCS101 Grade: 6 Title: Poptastic Abstract: The purpose of my project is to determine which brand of popcorn pops the most kernels. I chose this project because it is interesting because I like popcorn. First I got two bags of popcorn one kind was generic and the other one was the real kind. Next I opened both bags and counted the kernels in both bags and popped them then counted the kernels that weren’t popped. I determined that the Orville Redenbacker was the better value because although it started with fewer kernels, a higher percentage of the kernels popped. Project Number: JCS102 Grade: 6 Title: Household Cleaner - Effective Rust Removal Abstract: Student will test several easily accessible household cleaners for their effectiveness in removing rust. Project Number: JCS103 Grade: 6 Title: Keep It Fresh Abstract: The purpose of my project was to see what container keeps fruit fresh the longest. I defined” fresh” as having no brown spots. I tested apples, bananas, and pears in three different containers. The containers were a Sterilite plastic container with latches, a Giant Eagle brand plastic bag, and a Tupperware “Fridge Smart” container. I observed the fruit that was in the selected containers in the refrigerator at 2.8 degrees Celsius. I recorded time elapsed before any brown spot appeared on the nine samples. Project Number: JCS104 Grade: 6 Title: Toilet Paper Strength Abstract: What is the strongest brand of toilet paper? To answer my question I bought 3 different brands of toilet paper. The brands were Charmin, Angel Soft and Scott. To do this I took one square of toilet paper, attached a paper clip to the bottom of the toilet paper and attached a piece of tape to the top of the toilet paper. Then, I taped the toilet paper to the end of a table and slid washers down the paper clip till the toilet paper ripped in half. I tested each brand 3 times and recorded the results. The purpose of this project was to figure out what kind of toilet paper is the strongest and to do a cost analysis to determine the best buy and how to save some money. PRSEF Student Abstracts Page 37 Junior – Consumer Science (JCS) – 6th Grade Project Number: JCS105 Grade: 6 Title: Cereal is fe-tastic Abstract: The purpose of my science experiment is to see if i can extract iron from cereal and see which cereal out of the ones tested has the most iron in it. i chose this experiment because breakfast is supposed to be the most important meal of the day, and i thought it would be interesting to see how much iron is in the cereal you may eat everyday.My hypothesis is that total cereal has most iron because according to the Nutritional facts it has 100% iron.Smart starart also ha s100% iron but it is isted as "reduced iron" while total is listed as "Zink and iron mineral nutrients. Project Number: JCS106 Grade: 6 Title: What Antacid Neutralizes Best? Abstract: Have you ever experienced the occasional discomfort of heartburn? Do you use overthe-counter medication for it? Have you heard about natural heartburn remedies and wondered if they work? Well,I chose to do some experiments to see, one and for all, what works the fastest and the best. I must make clear, though, that chronic heartburn (persistent and recurring) is a sing of a serious problem. It is recommended to treat chronic heartburn with the remedies I've tested. Project Number: JCS107 Grade: 6 Title: Max's Choice Abstract: My project is what kind of dog food do dogs prefer best the purpose is to see what kind of dog food does my dog prefer best and it took around a couple days and it ended up being the wet dog food at the beginning it was hard dog food and the wet dog food he liked was chef Micheal"s now that is his main food but the dry dog food took him a while to eat that"s what won the wet dog food now he loves it Project Number: JCS108 Grade: 6 Title: Should you Garden with Rainwater? Abstract: Should you garden with rainwater My project was on what type of water made plants grow the best. I thought that rainwater would make plants grow better than tap water due to the amount of minerals in rainwater. I divided my counter into 3 stations, the rainwater, the tap water and the distilled water section. I watered each section with its designated water and measured the growth of the plant everyday. Overall, I had 24 plants, 8 plants in each section. 4 distilled water plants died, 2 rainwater plants died, and 1 tap water plant died. Although distilled water killed the most plants, my four tallest plants were in the distilled water section. In conclusion, rainwater does not make plants grow better than tap and distilled water. Jayanth Kashyap Project Number: JCS109 Grade: 6 Title: Stain Removal Comparison Abstract: I will determine which stain remover is the most efficient at removing stains. I believe it will be Oxi Clean Gel. To conduct the experiment, I will use four different stain PRSEF Student Abstracts Page 38 Junior – Consumer Science (JCS) – 6th Grade removers. I will put one ounce of each staining item on a 100% cotton shirt. I will do that for four shirts, using a different stain remover on each shirt. Each shirt will be washed for the same amount of time. I will compare the darkness of each stain, and conclude that the most efficient stain remover is the agent used on the shirt resulting with the lightest stain. Project Number: JCS110 Grade: 6 Title: Hook, Line, Sinker Abstract: The purpose of my project was to find out what fishing line is the strongest. I noticed when I go to fishing spots there is fishing line all over the ground. My hypothesis is that the braided fishing line will be the strongest because it is the thickest. I tested braided, monofilament, and fluorocarbon fishing lines. I added increasing amounts of mass to each line until it broke. I ran 5 tests for each type. My hypothesis was correct; the braided line could hold up to 2 times the size of its pound test, which was 10. With the information I have, I will use the braided line because it stretches the least and can hold the most weight. Project Number: JCS111 Grade: 6 Title: Chips Ahoy Abstract: When small objects such as chocolate chips are put in carbonated liquid, they float and sink. For my experiment, I am investigating what difference surface texture makes in the frequency that chocolate chips rise and fall in Sprite. Project Number: JCS112 Grade: 6 Title: Tasting With Your Eyes Abstract: Does the color of food affect how kids will think it will taste? I used 22 first Graders, 5 boxes of vanilla pudding dyed with food coloring. The colors I used were pink, blue, green, black, and yellow. I put them in one ounce cups for each kid to taste. As they tasted it, the would answer the question on the form I mad them, Color tasted __________, and did you like it, yes or no. Then I had a question, did you have a favorite tasting cup and a least favorite tasting cup. With all the data I gathered, I made graph charts and sorted out all the questionnaires and came up with some answers. In conclusion, after going through and doing the experiment, I found that the majority of the kids did think some of the colored pudding cups tasted different. It seems the more the kids liked the color, the better they thought it was. The majority of the girls like the pink the best, and the black the least. The boys seemed to like the black and blue the best, with the pink the least. Project Number: JCS113 Grade: 6 Title: The Effects of Stain Removal Abstract: My project was to find out which detergent removed three different stains the best. I used three different detergents, Oxi All (powder), Tide(liquid), and Woolite (liquid). The three different stains were grass, ketchup, and jelly. I put a detergent in the washer with the regular amount of detergent recommended for small loads. Then I did it again for the other detergents. Next, I repeated those wash loads, but used twice the detergent. The wash cycle and water PRSEF Student Abstracts Page 39 Junior – Consumer Science (JCS) – 6th Grade temperature was the same each time. My hypothesis was correct. Whe I doubled the amount of detergent, the stain was removed about twice as well. The jelly stain was the easiest to be removed and the grass stain was the hardest to remove. Project Number: JCS114 Grade: 6 Title: What Pan Heats the Fastest? Abstract: What type of pan heats the fastest? My hypothesis is if I test 4 different metal pans to see which one heats the fastest, I think cast iron will heat up the fastest. The purpose of my project is to determine what pan to use for certain foods so that they are cooked successfully without burning. I am testing 4 different types of pans: cast iron, ceramic, aluminum, and stainless steel. I recorded the temperature of the pan at intervals of 1, 2, 5, and 10 minutes. I used an infrared thermometer. The burner on the electric stove was set at #6 for all of the tests. My hypothesis was proven correct. Project Number: JCS115 Grade: 6 Title: Child Proof ? Abstract: I did this project because of Dr. Jay Arena's research in 1941. I gave a group of six children four bottles to attempt to open. I am going to quickly give you two examples of results from the first two bottles I tested. In test an the adult, multivitamin the longest time to open the bottle was 8 seconds and the shortest was 3 seconds. On bottle 2 the highest time was 8 seconds and lowest was 5 seconds. In conclusion, all subjects could open the bottles in under 30 seconds. We still have a lot of room for improvement Project Number: JCS116 Grade: 6 Title: Effective Batteries Abstract: My project was to find out which Battery would last the longest. My procedure to get this done is to place the flashlight I used in one location where temperature is not a factor in the results. After each flashlight lost power, I logged the data. What promoted my research is, if I am playing a video game that takes batteries I want to play as long as I can. What I found out is that utilitech died first at 5:18:30. The next one that died was Energizer at 6:13:03. Finally the battery that last the longest, Duracell at 8:50:32. Project Number: JCS117 Grade: 6 Title: What Bread Molds Fastest? Abstract: I decided to use wheat, white and rye bread for my experiment. My plan was to put each type in a separate sealed baggie and leave it sit out on the counter. I checked the breads three times a day to see if mold had begun to grow. I completed each trial three times. PRSEF Student Abstracts Page 40 Junior – Consumer Science (JCS) – 6th Grade Project Number: JCS118 Grade: 6 Title: What's The Beef? Abstract: I am testing 3 different types of ground beef and comparing how much fat gets drained from the cooked meat with how much fat the label indicates. I am doing this by cooking the meat and draining the fat into a measuring cup. I am testing 3 different fat percentages of ground beef from 3 different stores. I predict that the fat percentages will not be consistent with the labels. Project Number: JCS119 Grade: 6 Title: Coke vs. Pepsi: What gives for fizz for the pop Abstract: My experiment was to see whether the beverage Coke or Pepsi would make a bigger explosion when combined with Mentos candy. I tested this by pouring an even amount of Coke or Pepsi into a bottle. Then I put in a Mentos and corked it. I waited five minutes, loosened the cork and recorded how far the cork popped. I repeated this until I had four data points for each soda to see which one on average made the cork fly the farthest. After the experiment I found that Pepsi shot the cork farther and was better. Project Number: JCS120 Grade: 6 Title: Loaded Diapers Abstract: The purpose of my experiment is to see what diaper brand is the most absorbent. I hypothesize that Pampers will absorb the most water. I conducted this experiment by testing four different brands of diapers. I poured 10ml of warm water at a time to each diaper until the diaper started to leak and recorded results. I performed three trials of each. Based on the results, Pampers is the most absorbent diaper. My hypothesis was correct. Project Number: JCS121 Grade: 6 Title: Up In Flames Abstract: I did this project to see how I can help people with burning clothes. I also did this to see the flammability of fabric. To do this experiment I first fireproofed fabric. Then I got a fireproofed and regular piece of cloth and burned them. I time the burning and recorded information. I learned that fabric is flammable and can be treated. If you do it right, you can fireproof fabric and it won’t burn. Fireproofing can be an improvement to life and keep clothes from burning. Natural materials burn better, but when treated, can be almost un-burnable. Project Number: JCS122 Grade: 6 Title: Shamwow vs. Terry Towels Abstract: The purpose of this experiment is to find out if a Shamwow is more absorbant than a Terry Towel. To conduct my experiment I compared the absorbancy of the Shamwow and Terry Towel. The experimental results were measured by seeing what had the least amount of wrings. The results of my experiment showed that the Shamwow was more absorbant than a Terry Towel. The results indicate that the hypothesis should be accepred because the Shamwow only took 73 wrings in total to wring the water out, and the Terry Towel took at least 270 wrings to wring the water out. PRSEF Student Abstracts Page 41 Junior – Consumer Science (JCS) – 6th Grade Project Number: JCS123 Grade: 6 Title: Childproof? Abstract: My project is called 'Childproof?' and I am testing to see if children can open childproof containers. I expect that 50% of children will succeed in opening their bottle. To gather data I will give children a sanitized medicine bottle that used to contain iron pills. They have one minute to open it, and, if they fail I will show them how to open it without words. They will then have one minute to try again. I plan on testing the entire kindergarten at my school for precise data. Project Number: JCS124 Grade: 6 Title: Font-tastic Abstract: Do color and font affect the way a person pereives what they are reading? Project Number: JCS125 Grade: 6 Title: Taking the Play Out of Play-Doh Abstract: The purpose of my project is to see if Play-Doh® and homemade molding dough change in mass and volume as they are handled. I will do this by using a graduated cylinder, and a triple beam balance to determine the density of the purchased dough and the homemade dough. I divided both types of dough into 25 gram portions and rolled them with a rolling pin for 5, 10, and 15 minute periods. After each test, density was found of each sample and compared to the original density. Project Number: JCS126 Grade: 6 Title: Which battery lasts the longest? Abstract: Abstract My project was about what battery lasted the longest. The items I needed for my project were batteries, flashlights,poster board,paper,glue,markers,and pencils. What I did for my project was I used 3 different types of batteries to see which one lasted the longest. The steps of my project are to put 3 different types of batteries into 3 of the same types of flashlights then turn each of them on at the same time and wait to see which one lasts the longest. My results were that Duracell lasted the longest then Energizer, and finally Sunbeam came in third. Project Number: JCS127 Grade: 6 Title: Whiter and Brighter? Abstract: The purpose of my project is to brighten teeth. I see many advertised whitening products but they are expensive. So I set out to find something cheap and easy. I tested three different toothpastes that I had purchased at the Dollar Store. I tested Colgate Max Fresh, Ultrabrite Advanced Whitening, and Crest Whitening with Scope. I used eggs instead of teeth and soaked them in coffee for 22 minutes. I ran three tests and I brushed 9 eggs with each brand of toothpaste. I rated the whitening by comparing the eggs to a tooth shade guide. If I were to PRSEF Student Abstracts Page 42 Junior – Consumer Science (JCS) – 6th Grade do this project again I would change the brands of toothpastes used and increase the number of tests. The results will help America have brighter and whiter smiles. Project Number: JCS128 Grade: 6 Title: Yum Yum Breakfast Gum Abstract: The purpose of my project is to determine if I can create breakfast gum. I became interested because I love breakfast and gum. I made gum using wax and then I made gum using fondant with marshmallows. I then tested how long the flavor of each type of gum lasted compared to Juicy Fruit. The wax gum lasted for about a minute, then the fondant one lasted about 4 to 5 minutes. The second experiment turned out better than the first but I learned that fondant and marshmallows melt after a while because there candy related and there made of sugars and we all know sugar melts in water. Gum base doesn’t melt because it’s a type of rubber and fondant melts because it’s made of sugar. Project Number: JCS129 Grade: 6 Title: Band Aid Wars Abstract: The purpose of my project is to see which bandage brand has the most durability. I hypothesized that Band-aid would be the best bandage. I tested three brands of bandages: Bandaid, Nexcare, and Curad brands. I’m testing their durability by simulating different things one might do during the day. I attached them to PVC pipe to see how well they adhere. The soapy water test is to show how long a bandage might last when showering or washing hands. The washers are to see how strong the bandages are. The boiling water is to see how much heat they can take. I recorded all data and determined that my hypothesis was proven incorrect. Project Number: JCS130 Grade: 6 Title: Toilet Paper Power Abstract: The purpose of my experiment was to find the relationship between toilet paper ply and strength. I applied water to a strip of toilet paper, put a penny on the wet toilet paper, and timed how long it took the penny to penetrate the toilet paper. My hypothesis was, the 1 ply would be the weakest, the 2 ply would be in the middle, and the 3 ply would be the strongest. My hypothesis was correct. Out of the three brands tested, Cottonelle was the strongest, Angel Soft was in the middle, and Scott was the weakest. Project Number: JCS131 Grade: 6 Title: A Diaper's Capacity Abstract: The purpose of my experiment is to find out which diaper is most absorbent Pampers, Huggies or Target brand. The procedures of my experiment are to put one diaper of each brand into a medium sized bowl and pour water from a graduated cylinder onto the diaper evenly. Then wait five minutes for the water to absorb and then any water left in diaper, pour into bowl. Pour leftover water into graduated cylinder and measure how much each diaper absorbed from 1000ml. The results of this experiment were that Pampers absorbed all of the water over Huggies and Target brand PRSEF Student Abstracts Page 43 Junior – Consumer Science (JCS) – 6th Grade Project Number: JCS300 Grade: 6 Title: Glowtastic Abstract: We chose to investigate different brands of glow sticks and temperatures to see which lasted longest because we wanted to know which brand to buy. We put glowsticks into different temperatures of water: cold, warm, room temperature, and then we put them on our wrists to measure body temperature. We recorded the time when they fizzled out. In cold, warm, and room temperature water Super Glow lasted the longest. In body temperature, Super Glow fizzled out first while Glow lasted the longest. Our conclusions were that Glow is the best to wear and all glow sticks lasted longer in warm water. PRSEF Student Abstracts Page 44
