Life Science

Ch. 2 – Living Things & Their Environment

Chapter Review Questions

1. What changes would you expect to occur in a rain forest ecosystem after a large fire?

2. What is the difference between biotic and abiotic factors? Give examples of two biotic factors and three abiotic factors.

3. Describe three differences between a desert ecosystem and a rainforest ecosystem.

4. A coyote is a kind of wild dog. Coyotes eat mostly rabbits and rodents. Rabbits and mice eat the grass in pastures. Ranchers and farmers claim that coyotes kill many of their animals. How would eliminating many coyotes affect the cattle herds belonging to the ranchers and farmers?

5. Poison was left in pieces of meat where coyotes would find them. In addition to killing coyotes, what else do you think might happen?

Earth Science

Ch. 3 – Rocks & Minerals

Chapter Review Questions

1. Name two different kinds of sedimentary rock, explain how they are formed. Include what materials each rock is made of.

2. Anthracite coal and bituminous coal are fossil fuels that can be burned to produce heat and electricity. In what way does the term “fossil fuel” describe the origin of these rocks? If people continue to use the fossils fuels, why will we eventually run out of them?

3. You find a type of rock you haven’t seen before. What clues would you look for to determine whether it is igneous, sedimentary, or metamorphic? What would these clues tell you about what kind of rock it is?

Earth Science

Ch. 4 – Slow Changes on Earth

Chapter Review Questions

1. How would you design an experiment to determine the effect of plants on soil erosion?

2. A new brick building is constructed at your school. What will happen to the brick over time as it is exposed to the Sun, wind, and weather?

3. You find a jagged rock and a smooth rock along the banks of a river and think that the smooth rock is made from softer minerals. Write a hypothesis for an experiment to test this idea.

4. How are physical weathering and chemical weathering alike? How are they different?

5. How do erosion and deposition work together to change the shape of the land?

6. Loggers cut and remove all of the trees in a rainforest. How is the area most likely to change over time?

7. You hypothesize that fast flowing rivers cause more erosion then slow rivers? Explain how you would test your hypothesis.

2. Why do earthquakes occur along faults?

3. If you were going to build an emergency shelter to serve citizens during natural disasters, what issues would you consider before purchasing the land?

4. Draw and describe the three different types of volcanoes.

5. What are the main differences between a mudslide and a landslide? What kind of damage can both cause?

6. What are the 3 types of faults found in Earth’s crust? How do the plates move in one?

7. Why is it important to know where Earth’s plates are located and how they move?

8. What type of warning system can scientists use to monitor tsunami development?

Physical Science

Ch. 6 – Electricity

Chapter Review Questions

1. What would happen if your body had a balanced number of charges and you touched a negatively charged object?

2. You plug in a string of patio lights and notice that one bulb is missing. Infer whether the lights are connected in a parallel circuit or in a series circuit.

3. Write a hypothesis stating how a fuse is used to prevent too much electric current from flowing through a circuit.
