Sandy's teacher gave her a low grade for many reasons. First of all, she did not form a hypothesis. Also, Sandy did not form questions to be answered after the experiment was over.

For a well coordinated experiment, Sandy would have formed a hypothesis. For example, if rap music is played to a pea plant then the pea plant will grow exceptionally. Then, Sandy should have used identical pea plant seeds in the same soil, watered the same amount, and given the same amount of sunlight. The only varying factor in her experiment should have been the rap music being played
