What is the second step in the scientific method

Form a hypothesis

This would be the _________variable. How the moth reacts to the different light levels (distance to light source) would be the _________variable.

Independent, dependent

What is the third step of the scientific method

Test the hypothesis

This is the factor that changes in the experiment

Variable
