1. Independent variable = Cause Writing a Hypothesis: Dependent variable = Effect An independent variable is a condition or ________________________________________ in the experiment. Example 1:_______________________________ Example 2:_______________________________ Example 3:_______________________________ A good hypothesis is ____________________________. Just because a hypothesis is good doesn’t mean it has to be _________________! Has to be written in the ____________________ format The “if…then…” format helps to show a clear relationship between the _____________________and _____________________________. Your hypothesis should be _______________________! *Rule of thumb: ______________________________* Dependent variable is the factor of the experiment that is __________________________________________ _________________________________________.
