A science student makes the following statement. Plant growth is affected by the color of light.
What is the student doing?

making a hypothesis and then testing it in an experiment.

Explanation:

The color of light does affect plant growth. See, sunlight contains many colors of the visible specturm, and the invisible. Plants can be affected. Cellophane tents don't work because they don't supply the correct amount and cellophane affects opaqueness of the light... so use colored light bulbs. Plants (expecially flowering and house) tend to like violet, blue and red lights... not so much as some yellows, oranges and greens. Maybe this should help!
