Question

A student is measuring plant growth in an experiment. Using the same species of plant, he places one plant in the dark and one in artificial light. He hypothesizes that, over time, the plant in the artificial light will grow larger than the plant in the dark. What is the dependent variable in this experiment? Artificial light Plant growth over time Species of plant Time in light versus dark

Answer 1

A dependant variable is a variable in an experiment that is being studied or measured. A dependent variable's value depends on another.

Keeping this in mind, the dependent variable would be plant growth over time. The plant's growth is affected by its light source, the amount of time it's in the light/darkness, and the species of plant.

Hope this helps!
