INTERPRETTING DATA AND THE SCIENTIFIC METHOD

12.

[5 points] Using the data on water withdrawal in the U.S. and the plot you created in question

11, create a testable hypothesis to explain the trends in water withdrawal. This scenario does

not have to be true it has to be testable (able to be supported with further research or

experiments). Keep them appropriate.

13.

[5 points] There are two trees, Tree A and Tree B, that grow under very specific temperature

conditions. Design an experiment that tests for what temperature ranges Tree A and Tree B

grow best.

ENVIRONMENTAL SCIENCE & ECONOMIES

14.

[5 points] What are the four ways we can measure the wealth of nations? What are the

problems with only using GNP and GDP to measure national wealth?

15.

[5 points] Explain why understanding the impact human activity has on the environment is

important to determining economic policies?

EARTH AND ITS RESOURCES

16.

[10 points] Most plastics are considered organic compounds (made of combinations of

carbon with hydrogen and oxygen). What happens to plastics that are in landfills, dumps, or

in the ocean? (In other words: How long does it take them to decompose?) Using this

information and the Law of Conservation of Matter, what is happening to the carbon,

hydrogen, and oxygen used in plastics? Why might this be a problem?
