Question

To test the hypothesis that plants grow faster in green light, a student set up 3 of the same type of plants. She placed the first plant under a green light, the second plant under a regular light bulb, and the third plant under a red light. What is the dependent variable in this experiment?

Answer 1

The dependent variable in the experiment is the plant because the plant depends on the light to help it grow. The light is the independent variable.
