For a science class project, Sandy wants to test the effect of rap music on pea plant growth. She plays loud rap music 24 hours a day to a series of pea plants grown under light and watered daily. At the end of her experiment, she concludes that rap is conducive to plant growth. Sandy receives a low grade on this experiment from her teacher.

Why did Sandy’s teacher give a low grade for this experiment? What was the key problem with it? How could Sandy change her experiment to fix the problem? Rewrite the experiment so it will receive a better grade.

Please help me, I don't understand it
