Whenever an experiment is conducted, the scientist performing the experiment must know what he is trying to prove. Actually, scientists rarely prove anything. Normally, they "support" or "reject" their hypothesis.

In this exercise you will have the chance to develop several hypothesis that might be tested in a laboratory. Note: you will not necessarily test any of your hypothesis, but each one must be TESTABLE. (just in case)

Below is a list of "observations" made by someone such as yourself. Based on the observations, develop a workable hypothesis that could be used to test some aspect of the observation. Remember, an HYPOTHESIS is an EDUCATED GUESS that is TESTABLE. You must use complete sentences.
