All rights reserved. 5 Sample Primary Sources The Federalist No. 51 Publius (James Madison) February 6, 1788 To the People of the State of New York: TO WHAT expedient, then, shall we finally resort, for maintaining in practice the necessary partition of power among the several departments, as laid down in the Constitution? The only answer that can be given is, that as all these exterior provisions are found to be inadequate, the defect must be supplied, by so contriving the interior structure of the government as that its several constituent parts may, by their mutual relations, be the means of keeping each other in their proper places. Without presuming to undertake a full development of this important idea, I will hazard a few general observations, which may perhaps place it in a clearer light, and enable us to form a more correct judgment of the principles and structure of the government planned by the convention. In order to lay a due foundation for that separate and distinct exercise of the different powers of government, which to a certain extent is admitted on all hands to be essential to the preservation of liberty, it is evident that each department should have a will of its own; and consequently should be so constituted that the members of each should have as little agency as possible in the appointment of the members of the others. Were this principle rigorously adhered to, it would require that all the appointments for the supreme executive, legislative, and judiciary magistracies should be drawn from the same fountain of authority, the people, through channels having no communication whatever with one another. Perhaps such a plan of constructing the several departments would be less difficult in practice than it may in contemplation appear. Some difficulties, however, and some additional expense would attend the execution of it. Some deviations, therefore, from the principle must be admitted. In the constitution of the judiciary department in particular, it might be inexpedient to insist rigorously on the principle: first, because peculiar qualifications being essential in the members, the primary consideration ought to be to select that mode of choice which best secures these qualifications; secondly, because the permanent tenure by which the appointments are held in that department, must soon destroy all sense of dependence on the authority conferring them. It is equally evident, that the members of each department should be as little dependent as possible on those of the others, for the emoluments annexed to their offices. Were the executive magistrate, or the judges, not independent of the legislature in this particular, their independence in every other would be merely nominal. But the great security against a gradual concentration of the several powers in the same department consists in giving to those who administer each department the necessary constitutional means and personal motives to resist encroachments of the others. The provision for defense must in this, as in all other cases, be made commensurate to the danger of attack. Ambition must be made to counteract ambition. The interest of the man must be connected with the constitutional rights of the place. It may be a reflection on human nature, that such devices should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions. This policy of supplying, by opposite and rival interests, the defect of better motives, might be traced through the whole system of human affairs, private as well as public. We see it particularly displayed in all the subordinate distributions of power, where the constant aim is to divide and arrange the several offices in such a manner as that each may be a check ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC. All rights reserved. 6 on the other that the private interest of every individual may be a sentinel over the public rights. These inventions of prudence cannot be less requisite in the distribution of the supreme powers of the State. But it is not possible to give to each department an equal power of self-defense. In republican government, the legislative authority necessarily predominates. The remedy for this inconveniency is to divide the legislature into different branches; and to render them, by different modes of election and different principles of action, as little connected with each other as the nature of their common functions and their common dependence on the society will admit. It may even be necessary to guard against dangerous encroachments by still further precautions. As the weight of the legislative authority requires that it should be thus divided, the weakness of the executive may require, on the other hand, that it should be fortified. An absolute negative on the legislature appears, at first view, to be the natural defense with which the executive magistrate should be armed. But perhaps it would be neither altogether safe nor alone sufficient. On ordinary occasions it might not be exerted with the requisite firmness, and on extraordinary occasions it might be perfidiously abused. May not this defect of an absolute negative be supplied by some qualified connection between this weaker department and the weaker branch of the stronger department, by which the latter may be led to support the constitutional rights of the former, without being too much detached from the rights of its own department? If the principles on which these observations are founded be just, as I persuade myself they are, and they be applied as a criterion to the several State constitutions, and to the federal Constitution it will be found that if the latter does not perfectly correspond with them, the former are infinitely less able to bear such a test. There are, moreover, two considerations particularly applicable to the federal system of America, which place that system in a very interesting point of view. First. In a single republic, all the power surrendered by the people is submitted to the administration of a single government; and the usurpations are guarded against by a division of the government into distinct and separate departments. In the compound republic of America, the power surrendered by the people is first divided between two distinct governments, and then the portion allotted to each subdivided among distinct and separate departments. Hence a double security arises to the rights of the people. The different governments will control each other, at the same time that each will be controlled by itself. Second. It is of great importance in a republic not only to guard the society against the oppression of its rulers, but to guard one part of the society against the injustice of the other part. Different interests necessarily exist in different classes of citizens. If a majority be united by a common interest, the rights of the minority will be insecure. There are but two methods of providing against this evil: the one by creating a will in the community independent of the majority that is, of the society itself; the other, by comprehending in the society so many separate descriptions of citizens as will render an unjust combination of a majority of the whole very improbable, if not impracticable. The first method prevails in all governments possessing an hereditary or self-appointed authority. This, at best, is but a precarious security; because a power independent of the society may as well espouse the unjust views of the major, as the rightful interests of the minor party, and may possibly be turned against both parties. The second method will be exemplified in the federal republic of the United States. Whilst all authority in it will be derived from and dependent on the society, the society itself will be broken into so many parts, interests, and classes of citizens, that the rights of individuals, or of the minority, will be in little danger from interested combinations of the majority. In a free government the security for civil rights must be the same as that for religious rights. It consists in the one case in the multiplicity of interests, and in the other in the multiplicity of sects. The degree of security in both cases will depend on the number of interests and sects; and this may be presumed to depend on the extent of country and number of people comprehended under the same government. This view of the subject must particularly recommend a proper federal system to all the sincere and considerate friends of republican government, since it shows that in exact proportion as the territory of the Union may be formed into more circumscribed Confederacies, or States oppressive combinations of a majority will be facilitated: the best security, under the republican forms, for the rights of every class of citizens, will be diminished: and consequently the stability and independence of some member of the government, the only other security, must be proportionately increased. Justice is the end of government. It is the end of civil society. It ever has been and ever will be pursued until it be obtained, or until liberty be lost in the pursuit. In a society under the forms of which the stronger faction can readily unite and oppress the weaker, anarchy may as truly be said to reign as in a state of nature, where the weaker individual is ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC. All rights reserved. 7 not secured against the violence of the stronger; and as, in the latter state, even the stronger individuals are prompted, by the uncertainty of their condition, to submit to a government which may protect the weak as well as themselves; so, in the former state, will the more powerful factions or parties be gradually induced, by a like motive, to wish for a government which will protect all parties, the weaker as well as the more powerful. It can be little doubted that if the State of Rhode Island was separated from the Confederacy and left to itself, the insecurity of rights under the popular form of government within such narrow limits would be displayed by such reiterated oppressions of factious majorities that some power altogether independent of the people would soon be called for by the voice of the very factions whose misrule had proved the necessity of it. In the extended republic of the United States, and among the great variety of interests, parties, and sects which it embraces, a coalition of a majority of the whole society could seldom take place on any other principles than those of justice and the general good; whilst there being thus less danger to a minor from the will of a major party, there must be less pretext, also, to provide for the security of the former, by introducing into the government a will not dependent on the latter, or, in other words, a will independent of the society itself. It is no less certain than it is important, notwithstanding the contrary opinions which have been entertained, that the larger the society, provided it lie within a practical sphere, the more duly capable it will be of self-government. And happily for the REPUBLICAN CAUSE, the practicable sphere may be carried to a very great extent, by a judicious modification and mixture of the FEDERAL PRINCIPLE. PUBLIUS. The original text of the Federalist Papers (also known as The Federalist) was obtained by the Library of Congress from the e-text archives of Project Gutenberg FEDERALIST NO. 51 (1788) Excerpt “It may be a reflection on human nature, that such devices [checks and balances] should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions.” “. . . [I]n the federal republic of the United States… all authority in it will be derived from and dependent on the society, the society itself will be broken into so many parts, interests, and classes of citizens, that the rights of individuals, or of the minority, will be in little danger from interested combinations of the majority.” All of the Constitution’s checks and balances, Madison concludes, serve to preserve liberty by ensuring justice. Madison explained, “Justice is the end of government. It is the end of civil society.” ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

"The station buildings were long, low huts, made of sun-dried, mud-colored bricks, laid up without mortar (adobes the Spaniards call these bricks, and Americans shorten it to 'dobies.)The roofs, which had no slant to them worth speaking of, were thatched and then sodded or covered with a thick layer of earth, and from this sprang a pretty rank growth of weeds and grass. It was the first time we had ever seen a man's front yard on top of his house. The buildings consisted of barns, stable-room for twelve or fifteen horses, and a hut for an eating room for passengers. This latter had bunks in it for the station-keeper and a hostler or two. You could rest your elbow on its eaves, and you had to bend in order to get in at the door. In place of a window there was a square hole about large enough for a man to crawl through, but this had no glass in it. There was no flooring, but the ground was packed hard. There was no stove, but fire-place served all needful purposes. There were no shelves, no cupboards, no closets. In a corner stood an open sack of flour, and nestling against its base were a couple of black and venerable tin coffee-pots, a tin teapot, a little bag of salt, and a side of bacon. By the door of the station keeper's den, outside, was a tin wash-basin, on the ground. Near it was a pail of water and a piece of yellow soap, and from the eves hung a hoary blue woolen shirt, significantly - but this latter was the station-keeper's private towel, and only two persons in all the party might venture to use it - the stage-driver and the conductor.“ Mark Twain, Roughing It (1872) ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Was it created through a spur-of-the-moment act, a routine transaction, or a thoughtful, deliberate process? 2. Did the recorder have firsthand knowledge of the event? Or, did the recorder report what others saw and heard? 3. Was the recorder a neutral party, or did the creator have opinions or interests that might have influenced what was recorded? 4. Did the recorder produce the source for personal use, for one or more individuals, or for a large audience? 5. Was the source meant to be public or private? 6. Did the recorder wish to inform or persuade others? (Check the words in the source. The words may tell you whether the recorder was trying to be objective or persuasive.) Did the recorder have reasons to be honest or dishonest? 7. Was the information recorded during the event, immediately after the event, or after some lapse of time?

Introduction: The purpose of this activity is to get the students to think about the nature of science, and also, to show the importance of being an active participant in the learning process. This activity supports the abilities necessary to understand and engage in scientific inquiry. Materials: Print the following pattern on cardstock paper and cut out the individual pieces. Make enough for each student to work individually. Procedure: Hand out all the pieces except the small square marked X. Each piece represents current scientific data. Once the students are given the pieces, provide no further instruction. Most students will begin to arrange the pieces on their own. In a short amount of time, the students will put the pieces together to make a square as seen below in Figure 2. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC. All rights reserved. 16 Once all the students have arranged the pieces to produce figure 2, hand out the small square marked X to each student and explain that a new scientific discovery has been made. Students must somehow incorporate this new information to their puzzle. Encourage students to work individually at first, and then, to work in groups if the frustration level rises. There may be some degree of collaboration (looking at other student’s progress). If one student gets the correct arrangement, have that student cover up the answer so that other students will persevere. Hint: You may help students get started by having them make the “Superman” logo shape first. Follow-Up Questions: Once all or most of the students have arranged the pieces correctly, have them brainstorm and share how this activity is similar to “doing” science. Similarities may include the following ideas: 1. Assume that the pieces fit together – nature is a puzzle that we have not yet solved 2. Trial and error is an essential ingredient to science 3. New information may require the old theory to be modified or discarded 4. Current information may be incomplete and therefore, theories are incorrect 5. Sometimes, a person gets lucky and finds the right answer 6. Collaboration may be helpful 7. Once the answer is arrived at, it makes perfect sense Share with students that scientific design (the scientific method) requires the same types of thinking as the puzzle. Questions, such as, Why, Why Not, and How are important when determining whether the outcomes of an experiment make sense or not.

The 5Es sequence the learning experience so that the learners construct their understanding of a concept across time. Each phase of the learning sequence can be described using five words that begin with "E": engage, explore, explain, extend, and evaluate. Engage Begin each unit or topic with a lesson or activity that engages students with an activity or question as they are introduced to the concept. Students should make connections to prior knowledge and what is to be studied. During this phase, teachers ask questions of students and engage them in the guided inquiry lessons. They use strategies such as KWL or ABC Brainstorm that make connections between the past and present learning experience. Explore Have students carry out hands-on activities in which they explore the concept or skill. This phase allows students to acquire a common set of experiences that they can use to help each other make sense of the new concept or skill. Teachers should set up the investigation and guide students in inquiry, asking probing questions to clarify understanding. Explain After students have explored the concept or skill, the teacher provides the concepts and terms used by the students to develop explanations for the phenomenon they have experienced. The significant aspect of this phase is that explanation follows experience. Teachers should ask probing questions that encourage students to look for additional information. Elaborate Students expand their learning, practice skills and behavior, and make connections or applications to related concepts and in the world around them. Teachers provide learning opportunities for students to apply their knowledge and to gain a deeper understanding. Activities can include reading articles and books, writing, designing other experiments, and exploring related topics on the Internet. Provide opportunities for students to apply what they have learned to new situations. It is important for students to discuss and compare their ideas with each other during this phase. Evaluate The final phase provides an opportunity for students to review and reflect on their own learning and new understandings and skills. This is the phase where students provide evidence for changes to their understandings, beliefs, and skills. Teachers should assess students understanding through both formative and summative activities. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC. All rights reserved. 23 An Overview of the 5Es Purpose Role of Teacher Engage Phase Create interest and stimulate curiosity. Set learning within a meaningful context. Raise questions for inquiry. Reveal students’ ideas and beliefs, compare students’ ideas. Explore Provide experience of the phenomenon or concept. Explore and inquire into students’ questions and test their ideas. Investigate and solve problems. Explain Introduce conceptual tools that can be used to interpret the evidence and construct explanations of the phenomenon. Construct multi-modal explanations and justify claims in terms of the evidence gathered. Compare explanations generated by different students/groups. Activity or multi-modal text used to set context and establish topicality and relevance. Motivating/discrepant experience to create interest and raise questions. Open questions, individual student writing, drawing, acting out understandings, and discussion to reveal students’ existing ideas and beliefs so that teachers are aware of current conceptions and can plan to extend and challenge as appropriate – a form of diagnostic assessment. Open investigations to experience the phenomenon, collect evidence through observation and measurement, test ideas and try to answer questions. Investigation of text-based materials (e.g. newspaper articles, web-based articles) with consideration given to aspects of critical literacy, including making judgments about the reliability of the sources or the scientific claims made in the texts. Student reading or teacher explanation to access concepts and terms that will be useful in interpreting evidence and explaining the phenomenon. Small group discussion to generate explanations, compare ideas and relate evidence to explanations. Individual writing, drawing and mapping to clarify ideas and explanations. Formative assessment to provide feedback to teacher and students about development of investigation skills and conceptual understandings. Small group writing/design to generate a communication product (e.g. poster, oral report, formal written report or PowerPoint presentation, cartoon strip, drama presentation, letter) with attention to form of argumentation, genre form/function and audience, and with integration of different modes for representing science ideas and findings. Further investigations, exercises, problems or design tasks to provide an opportunity to apply, clarify, extend and consolidate new conceptual understandings and skills. Further reading, individual and group writing may be used to introduce additional concepts and clarify meanings through writing. A communication product may be produced to re-represent ideas using and integrating diverse representational modes and genres consolidating and extending science understandings and literacy practices. Elaborate Use and apply concepts and explanations in new (extend) Evaluate contexts to test their general applicability. Reconstruct and extend explanations and understandings using and integrating different modes, such as written language, diagrammatic and graphic modes, and mathematics. Provide an opportunity for students to review and reflect on their own learning and new understandings and skills. Provide evidence for changes to students’ understandings, beliefs and skills. ® Discussion of open questions or writing and diagrammatic responses to open questions – may use same/similar questions to those used in Engage phase to generate additional evidence of the extent to which the learning outcomes have been achieved. Reflections on changes to explanations generated in Engage and Evaluation phases to help students be more metacognitively aware of their learning.

Materials paint tray (the kind used for a paint roller) pieces of sod (enough for each group) potting soil heavy clay like soil rainmaker (paper cup with about ten tiny holes poked in the bottom) water Process Using the 5Es Model Engagement Take students on a walk outside of the school building and note where the soil is worn away or seems to have collected. Have students make a list of the sites. Ask students: • Do you notice anything different about these areas? • What do you think caused these changes? Exploration Have students construct a model to investigate how these changes may have occurred. Provide students with materials so that they can construct their own model of a landscape. It should include a piece of sod, fine potting soil, and a heavy clay-like soil. Have them use a paint roller tray as the base of their model. Share with students that they should not put any landscape materials in the bottom well. Once students have constructed their models, have them diagram and label their models and make a prediction as to what will happen if it “rains” on their landscape. Have students put a full glass of water into their rainmaker and slowly move the rainmaker over their model. Students should hold the rainmaker about 4 inches above the upper end of the landscape and slowly move it back and forth so the water “rains” down on the model landscape. Have students observe what happens to their landscape when rain occurs. When it is finished raining, have the students observe the final effects of the rain on their landscape. Have students go back to their predictions and record what actually happened. Explain Ask students: • What were your predictions before it rained on your landscape? • What happened to your landscape when it rained? • How is your landscape different after the rain than before the rain? • What happened to the soil? Where did it go? Why did this happen? Explain erosion, transportation, and deposition. Discuss that water was used during this experiment to simulate erosion, transportation, and deposition, but erosion can also be caused by wind, people, animals, etc. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC. All rights reserved. 25 Elaborate (extend) Have groups of students plan a method to decrease or eliminate erosion. Have them design another landscape using the same roller pan and resources as a base for their landscape. Students should draw a diagram of the model planned and label the materials used in their landscape. Have students write an explanation for why they think their plan will work to curb erosion. Have students experiment with their new landscape and describe whether or not their plan worked. Debrief by having students identify a real-world situation of erosion, what occurred, and what is being done to restore the environment. Evaluate Provide students with photographs representing different landscapes. Have students evaluate whether or not each landscape would be effective in preventing erosion. Have students define the terms erosion, transportation, and deposition and provide real-world examples of each. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Clean It Up When oil tankers accidentally spill their cargo of oil into the ocean they cause a huge environmental danger. Oil is extremely hard to remove from the water and the beaches, and the whole environment is damaged. In this experiment, you can see how hard it is to remove oil from sand. You will need: Large plastic cup Sand 2 tablespoons of vegetable oil (This experiment can be messy, so you might want to do it outdoors.) Step 1 – Observe - Fill a plastic cup with sand and oil and mix well. Observe the problem that you have. Step 2 – Hypothesize - Based on your observations, make a guess at what tools you could use to get the oil off the sand. Step 3 – Test the Hypothesis - Conduct an experiment. Use a spoon, a straw, paper towel, an old toothbrush, a sponge – anything that you can think of to get the oil off the sand and help save the environment! Friction Which is easier to spin – a smoother ball or a less smooth ball? For this experiment, you will need: A bowl of water Smooth rubber ball Tennis ball Step 1 – Observe the two types of balls. Step 2 – Hypothesize - Based on your observations, make a guess as to which ball will spin the longest and why. Step 3 – Test the Hypothesis - Try spinning the rubber ball in the water. Next spin the tennis ball in the water. Which one is easier to spin? The smoother ball is easier to spin because the smooth surface causes less friction with the water. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Students explore how the scientific method can be used to solve a problem or meet a challenge. You may choose to have your students design and construct their model, test it, revise it, and then write it up according to the scientific method, or write it up as they go along. Materials Per Group: 1 cup 1 marble 20 straws 12 inches of tape 6 rubber bands 4 mailing labels 10 paper clips 1 ruler 2 index cards 10 nails 1- 1-inch ball of Playdoh Student Directions: Using the materials listed below, you are to build a structure which will transport a marble into a cup. The structure must be at least 14 inches tall and must transport the marble a distance of no less than 24 horizontal inches (parallel to the floor). Once the marble is released it may not be touched until the trial is over. In order to accomplish the problem, the marble must remain in the cup when the trial is over. The marble must start on the structure and must remain on the structure for two seconds. You may use only the following materials: 1 cup 1 marble 20 straws 12 inches of tape 6 rubber bands 4 mailing labels 10 paper clips 1 ruler 2 index cards 10 nails 1- 1-inch ball of Playdoh Describe your solution in terms of the scientific method. Did you use all of the steps? Did you run a controlled experiment? What would be the benefits of using a control with this problem? Do all solutions to problems follow the scientific method? How could the scientific method have helped you to achieve your solution? ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Gelatin absorbs water to a certain extent. There is a limit to how much water a certain amount of gelatin can hold. Salt is a solute and draws water towards it. Water moves toward the direction where there is more salt and less water. Vinegar is an acid and is corrosive. It can cause various substances to break down. Problem: How will a gummy bear be affected by water, salt water, sugar water and vinegar? Hypothesis: I think each of the following will affect a gummy bear in the following way: Water: _________________________________________________ Salt water: ______________________________________________ Vinegar: ________________________________________________ Sugar water: ____________________________________________ Materials: Gummy Bears Triple Beam Balance Metric Ruler Plastic Cups Water Salt Vinegar Sugar Procedure: 1. Collect materials. 2. Prepare cups and label: water, salt water, vinegar, and sugar water 3. Measure length, width, height and mass of each gummy bear. Record in data table. 4. Place one gummy bear in each solution. 5. Record observations after one and five minutes. 6. Leave overnight. 7. The following day, record observations of each gummy bear and measure length, width, height and mass of each gummy bear. 8. Find the percent increase in dimensions. 9. Draw a conclusion ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Component Hypothesis Definition/Description Quantitative Data Qualitative Data Repeated Trials Independent Variable Dependent Variable Control Constants The Experiment A shopping mall wanted to determine whether the more expensive “Tough Stuff” floor wax was better than the cheaper “Steel Seal” floor wax at protecting its floor tiles against scratches. One gallon or each type of floor wax was applied to each of the five test sections of the main hall of the mall. The test sections were all the same size and were covered with the same kind of tiles. Five (5) other test sections received no wax. After 3 weeks, the number of scratches in each of the test sections were counted. Component Example from “The Experiment” Reasoning Hypothesis Quantitative Data Qualitative Data Repeated Trials Independent Variable Dependent Variable Control Constants Adapted from Cothron, Julia, et al.

Find out which spins the longest, a raw egg or a cooked egg. For this experiment, you will need: 1 cooked egg 1 raw egg 1 plate Step 1 – Observe the two eggs. Step 2 – Hypothesize - Based on your observations, make a guess as to which egg will spin the longest and why. Step 3 – Test the Hypothesis - Spin each egg in turn on a plate. The egg that continues to spin for a longer time is the cooked one. Now spin the eggs again, and then quickly stop both of them. Then let go of both eggs. You will see that the cooked egg stays still but the raw one starts spinning again. Why does this happen? The contents of the egg have more inertia when they are raw, because they are in the form of a liquid. This inertia slows down the raw egg and that is why it stopped spinning before the cooked egg. In step 2, the liquid in the raw egg was still moving when you stopped both eggs, so that movement made the raw egg begin to spin again. Which Paper Towel Absorbs the Most Water Have students divide into small groups of three to four students. Provide each student with different rolls of paper towels (different brands and quality) and cups of water. Have them predict which towel will absorb the most water and why. Have them conduct the experiment and develop a short oneminute commercial that delivers their findings. Hypothesis: Which paper towel will absorb the most water? Why? Observations Paper Towel A Paper Towel B Paper Towel C What results can be drawn from the experiment? ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.

Materials: One bag of Tootsie Pops with at least 3 of each color. Make sure that none have been broken. Paper and pencil Procedure: 1. Identify the independent variable in this question. (the different colors/flavors) 2. Identify the dependent variable in this question. (same person doing the experiment for each color and ensure that the same amount of pressure and the same location on each pop is used) 3. Identify at least 3 constants (controls) for this question. (same person doing the experiment, lollipops that are the same size, same pressure used for each lick, same direction used for each lick such as from bottom to top, etc.) 4. State a hypothesis for this question. This is a prediction about how the independent variable will affect the dependent variable. The orange lollipop will take less time to get to the middle because it is a lighter and clearer color. 5. Write a procedure to test this hypothesis. What materials will you need to conduct this investigation? How many times will you replicate the experiment? 6. Design a data table to collect and display your results. What will you need to record? 7. Conduct the experiment. How many times will you replicate the experiment to prove or disprove your hypothesis? Why? 8. Determine the results and whether or not the hypothesis was supported by the data. ® GED Testing Service | www.GEDtestingservice.com © Copyright 2016 GED Testing Service LLC.
