Science is about finding answers to our questions about the world around us. Part of finding the answer is to test a hypothesis. A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon, event or scientific problem that can be tested by further investigation. A useful hypothesis is a testable, measurable statement. Then the rest of the scientific process helps us test if our hypothesis was correct or not.
What do you think will be the answer to your research question? That is your hypothesis. As you investigate, and perhaps refine, your question you may also refine your hypothesis – they go together.
