After reviewing the data and results in Steps 11 & 12, make a conclusion. According to your results, was the hypothesis proven or disproven? (Remember, it is OKAY for your hypothesis to be disproven!) Use your data as evidence for your conclusion and list specific examples of your data to support your statements.
Answer the following questions: Was there anything in the experiment that you would change if the hypothesis were retested? How could you change or expand this experiment if you were going to do it again? What did you learn from the experiment? How could this information be used to help people or to make the world a better place?
