How did your experiment support or contradict your original hypothesis? How could you improve your experiment? Did everything go as planned or were there unexpected results? Does what you learned lead to a new question to ask or experiment that would answer it? If so, why would it be important, interesting, or useful to do?
Judges' Tip An excellent conclusion will explain how the experiment answers the question or why it fails to do so and whether or not it supports the hypothesis (500 words maximum).
