Hypothesis

This week I got several e-mails from students (and parents) working on science fair projects. We will take a look at a word that many students, parents and teachers misunderstand. To see what I mean, lets start with an imaginary science project. Let's use a classic, which laundry detergent works best. I have judged quite a few science fairs, and this one always turns up.

Now the teacher says you need a hypothesis. What is the world is that? Many people will tell you that it is an educated guess, so you might think you should guess which one will work the best. A hypothesis is not a guess, but it should be educated.
