Variables and Graphing

When we are working on science experiments, we are dealing with several different things.

1. Independent Variables

2. Dependent Variables

3. Controlled Variables


Independent Variable: (IV)

  • Part of the experiment you are in control of
  • THE CAUSE
  • What you are changing

Dependent Variable: (DV)

  • Part of the experiment that changes because of the IV
  • THE EFFECT
  • Part of the experiment you are measuring

Controlled Variable: (CV)

  • Part of the experiment you keep the same throughout all stages of the experiment.
