Apply Inquiry and Review the Big Ideas

Write the answers to these questions.

Choose one important idea you studied in this unit. Describe how you would draw a model or diagram to demonstrate that idea. What information would you include? Your model or diagram should show things your audience could not see in the real world, such as Earth completely orbiting the sun.

5.3C

Review an experiment you read about in Unit 10. What valid conclusions can you communicate about the results of the experiment? Summarize the experiment and write and evaluate the conclusions in your own words.

5.2F, 5.3A

Earth’s circumference is the distance around it. Its circumference at the equator (the imaginary line that runs around the center of Earth) is 40,080 kilometers. Earth rotates once every
24 hours. What is its speed of rotation in kilometers/hour?
