Test 4 Study Guide Once you have your foldables in order, place them inside your folder. If you have all of your foldables, help the other people in your group get theirs in order. Move on to the next station when instructed.

2 WELCOME TO REVIEW STATION TWO Scientific Methods/Variables Review Complete the Simpsons Variables Review. Each person should choose one of the scenarios. Answer the questions and discuss with the people in your group. Once everyone in your group has completed this activity, check and correct your answers. When you are done, place the worksheet you completed in your folder. Move on to the next station when instructed.

3 Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks. Identify the: Control Group Manipulated Variable 3. Responding Variable 4. What should Smithers' conclusion be? 5. How could this experiment be improved? Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. 6. What was the initial observation? Identify the- 7. Control Group 8. Manipulated Variable 9. Responding Variable 10. What should Homer's conclusion be?

4 REVIEW STATION TWO ANSWERS Scientific Methods/Variables Review Group B is the control group. The manipulated variable is who is given the special juice. 3. The responding variable is the amount of work completed in the time measured. 4. The special juice did not make Group A work faster; in fact, the worked more slowly. 5. Increase the amount of work time; find the ingredients of the special juice and create a new drink (you may have other answers) 6. The green slime growing in the shower 7. The control group is the side of the shower that water was sprayed on. 8. The manipulated variable is the coconut juice. 9. The responding variable is the slime left at the end of the experiment. 10. Homer s conclusion should be that coconut juice will not get rid of green slime. 1 The ten mice not exposed to the microwaves. 1 The manipulated variable is exposing the mice to microwaves. 13. The responding variable is the mice who were able to push the block of wood out of the way. 14. Bart s conclusion should be that it appears that mice subjected to microwave radiation may increase their strength, but additional testing needs to be done. 15. Bart s experiment could be improved by checking out safe handing of animals. (You may have something else.)

5 16. The control group is the group given the normal itching powder. 17. The manipulated variable is the type of itching powder. 18. The responding variable is the length of itching. 19. It does support the claims because 45 minutes if 50% longer than 30 minutes.

9 WELCOME TO REVIEW STATION FOUR Soil Review Place the layers of soil in the correct order. Make sure that everyone in your group can answer the following questions: What is the first step in soil formation? What is soil? 3. What is loam? 4. What does it mean if something is permeable? 5. What is soil depletion? 6. What is the difference between the A Horizon and the B Horizon? 7. Put the soil particles in order for largest to smallest: clay, gravel, sand, silt. 8. What do living organisms do in the soil? Move on to the next station when instructed.

10 REVIEW STATION FOUR ANSWERS Soil Review Soil Layers/Horizons: O (litter/organic material), A, B, C (partial weathered bedrock), R (bedrock) 9. What is the first step in soil formation? weathering of rock particles 10. What is soil? the loose weathered material on Earth s surface in which plants can grow 1 What is loam? a type of soil made up of equal parts sand, silt, and clay 1 What does it mean if something is permeable? water can move through it 13.

15 REVIEW STATION SIX ANSWERS Plate Tectonics/Continental Drift Review 5. List the three types of plate boundaries. Give one geologic landform or event that occurs at the boundary. Be specific about what crust combination you are describing using the correct terms of continental crust and oceanic crust. a. Divergent boundary when two plates pull away from each other; continental-continental crust diverging causes rift valleys, and ocean-oceanic crust diverging create mid-ocean ridges. Sea floor spreading occurs here. b. Converging boundary when two plates collide; continental-continental crust converging create mountain ranges, oceanic-oceanic crust converging create subduction zones, deep ocean trenches, and island arc volcanoes, oceanic-continental crust converging creates subduction zones, deep ocean trenches, and volcanic mountain ranges. c. Transform boundary when two plates slip past each other moving in opposite directions; earthquakes often occur at these plate boundaries 6. What were Alfred Wegener s three pieces of evidence for continental drift? Give a specific example for each one. a. Landform/geologic evidence; examples: jigsaw fit of South America and Africa, folded mountain ranges that match up in South America and Africa, and similar coal fields in Europe and North America b. Fossil evidence; examples: fern (glossopteris) on several continents (Antarctica, Africa, South

16 America, India) but the seed pods were too big to be carried by wind and too fragile to travel the oceans, dinosaurs on several continents that could not have swum the ocean c. Climate evidence; examples: coal in Antarctica; fossils of tropical plants in an island near Iceland; glacier deposits in Africa 7. Continental drift the theory that all the continents were once joined in a single landmass called Pangaea and over million of years drifted to their present positions 8. Plate Tectonics the theory that the Earth s lithosphere is divided into plates that are in slow, constant motion

18 REVIEW STATION SEVEN ANSWERS Earthquake and Volcano Review 7. What is a subduction zone volcano? volcanoes that form along subduction zones the place where one plate is forced under another and melts back into the mantle; found around plate boundaries 8. What is a hot spot volcano? a volcano that forms in the middle of a plate where the mantle is hotter and melts through the crust; the Hawaiian islands are an example 9. What are the three types of volcano stress? Indicate what direction they move. a. Shearing moves rock in two opposite horizontal directions b. Tension pulls rock apart until it is thinner in the middle c. Compression pushes rock together until it folds or breaks 10. Draw a normal fault. 1 Draw a reverse fault. 1 Draw a strike-slip fault.
