Simon's sister collects crickets at night. Simon wonders if crickets prefer dark. He fills a long trough with soil and grass and covers one side with dark paper to keep out light. On the other side, he shines a light. He places the crickets in the middle of the trough and observes them to see where the crickets are after 10 minutes. He repeats this three times. What is the variable in this experiment?
How much light is the variable
