Station 1: Ecology
1) In some parts of the world people eat scorpions. Scorpions eat crickets. Crickets eat grains. Grains get their
energy from the sun.
a. Which of the organisms listed has the most biomass?
Grains
b. Fill in the levels of the energy pyramid (right) with the appropriate organisms.
Humans on top, scorpions, crickets, then grains on bottom
c. Label each of the layers of your pyramid as primary producer, primary
consumer, secondary consumer, and tertiary consumer.
Primary producers = grains, Primary consumer = crickets, secondary consumers
= scorpions, tertiary consumers = humans
2) Identify primary producers, primary consumers, secondary consumers, and tertiary consumers in the following
food web. (There are some organisms that are more than one type.)
Primary producers = grasses
Primary consumers = mouse, insects, rabbit, deer
Secondary consumers = mouse, shrew, snake, cougar
Tertiary consumer = snake
3) Why do we use food webs rather than food chains?
Because real life ecosystems are more complex than
only one thing eating another.
4) Draw a simple graph of exponential growth. Don’t
worry about specific numbering, just axis labels. 
Station 2: Energy
5) What is energy? (Scientific definition, popular definition, or your own explanation.)
Energy is the ability to do work. In other words, the ability to make things happen.
6) Fill in the blanks on the following energy transfers.
a. A light bulb turns electrical energy into radiant/light energy.
b. Friction turns motion energy into heat energy.
c. Burning fat turns chemical energy into motion/heat energy.
d. Rolling a ball down a hill turns gravitational energy into motion energy.
7) What is the Law of Conservation of Energy?
Energy cannot be created or destroyed.
8) What is the difference between renewable and non-renewable energy sources?
You can make more renewable energy, you can’t make non-renewable.
9) List 2 energy sources humans use, along with one pro and one con for each.
Answers will vary
Station 3: Waves
10) What happens to the wavelength in each of the following examples?
a. Go from red to blue light
Gets shorter
b. Go from high pitch to low pitch
Gets longer
11) What happens to the amplitude in each of the following examples?
a. Bright light to dim light
Gets lower
b. Soft sound to loud sound
Gets taller
12) Answer the following questions about light.
a. Name 3 types of light on the electromagnetic spectrum.
Radio, microwave, infrared, ultraviolet, x-ray, gamma ray
b. Which one of your examples has the most energy?
Examples above are arranged from lowest to highest energy, so whichever example is furthest right
c. What color of visible light has the most energy?
Blue/violet
13) Answer the following questions about sound.
a. Does high pitch or low pitch have more energy?
High pitch
b. What is the system used to measure the loudness of sound?
Decibels
14) Give an example of each of the following:
a. Convection
(Answers vary) Should involve the movement of substances, like boiling or steam.
b. Conduction
(Answers vary) Should involve touching, like a stove.
c. Radiation
(Answers vary) Should involve light, like infrared waves.
Station 4: Simple Machines
15) What is mechanical advantage? (Formula or word definition works.)
(Force out) / (Force in) In other words, the force you get out relative to the force you put in.
16) How do you figure out the mechanical advantage of a pulley?
The number of un-pulled ropes.
17) Identify the class of lever: Third class.
18) Would you expect moving a rock to be easier or harder with each of the following:
a. First-class lever
Same difficulty.
b. Second-class lever
Easier.
c. Third-class lever
Harder.
19) Give a practical example of each of the following simple machines:
a. Inclined plane
(Answers vary)
b. Lever
(Answers vary)
c. Wedge
(Answers vary)
20) A compound machine is a device that has two simple machines put together. What two simple machines make
up a…
a. Wheelbarrow
Lever + wheel/axle
b. Axe
Lever + wedge
Station 5: Chemistry
21) You dip a piece of pH testing paper into a solution and it comes out bright red. What does this mean? Acid
22) What happens to the rate of reaction when you…
a. Cool the solution
Slows the reaction.
b. Shake the solution
Speeds up the reaction.
c. Grind up the Alka-Seltzer before adding it to the water
Speeds up the reaction.
d. Add a catalyst
Speeds up the reaction.
23) Identify how many atoms are in the following:
a. 3O2 6
b. CO2 3
c. 2H2O 6
d. 5N2 10
e. H2 2
f. 2C6H12O6 48
24) Identify the molecules in the problem above.
a. oxygen, b. carbon dioxide, c. water, d. nitrogen, e. hydrogen, f. sugar
25) What is a coefficient telling you?
How many molecules you have.
26) What does a catalyst change about a chemical reaction? What does it not change?
It changes the activation energy, which in turn makes the reaction go faster. It does not change how much
product you get.
Station 6: Geology
27) Diagram the rock cycle (the diagram we drew from the board).
