  1. Writing a Good Hypothesis

  2. What is a Hypothesis? • A hypothesis is an educated guess about the answer to a question. • Research must be done before making a hypothesis. • A hypothesis is not just any prediction. It needs to be justified. That means you need to back up what you say with facts.

  3. IF, THEN, BECAUSE Format • A hypothesis looks at the effect of our independent variable on our dependent variable. • IF we change our independent variable, THEN how will our dependent variable change? • Example: IF you exercise, THEN you will get stronger.

  4. IF, THEN, BECAUSE Format • The BECAUSE is your justification. This is backed up with facts. • If you exercise, then you will get stronger, BECAUSE you are developing your muscles. • Try a hypothesis for the effect of eating too much ice cream on your weight.

  5. IF, THEN, BECAUSE Format • If you eat too much ice cream, then you will gain weight, because ice cream has a lot of calories that your body will store as fat. • Try some of the other examples on the worksheet!
