What does hypothesis meaning in a science fair project?

The Word hypothesis means the expected outcome of the experiment. Think of it as an educated guess or explanation of what you think will happen in your experiment based on what you have learned about your subject. It consists of two parts. Part one is the hypothesis statement. You make your hypothesis statement by rewriting your problem as a statement and adding the "answer" to it. BE SPECIFIC! Part two is a short explanation of the scientific reasoning for your hypothesis. And that is your answer for hypothesis!!
