Step 3: HypothesisA hypothesis is an educated guess about the outcome of your experiment. After you have found a topic, you should come up with a question about the topic. The question must be something that can be answered with an experiment and your hypothesis should answer that question. The hypothesis is an educated guess because you have already done your background research. It is perfectly fine if your hypothesis turns out to be wrong - in fact, we often learn more from a wrong hypothesis than a correct hypothesis.
