This week we are going to talk about developing a hypothesis. During the month of September we will be going over each step of the scientific method. Each week we will tackle a different component.
Your hypothesis is basically a prediction of what will happen or a question that you want to answer. For example, if you are developing a science fair project on combustion your hypothesis can be something like: When a fire is deprived of oxygen it will go out. As you can see this is a prediction about what will happen during your experiment. The second option that you have for your hypothesis is to ask a yes or no question about your topic, for example: Will a fire go out if the oxygen is removed?
When developing your science fair project’s hypothesis you want to keep it simple and to the point. A great hypothesis will address only one specific topic. If you are working with a complex science topic you can create several hypotheses to test.
Most students entering a science fair will only need to develop and refer to a single hypothesis. However, older students who are interested in producing an upper level project may also want to introduce a null hypothesis. A null hypothesis is basically the opposite of your hypothesis. This means that if your hypothesis is correct your null hypothesis will be incorrect, and vise versa.
