She decides to conduct an experiment to prove her theory. He places 10 crickets. variable changed or controlled by scientist. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly. She thinks that crickets chirp more often when the temperature gets warmer. If an experiment is conducted to see how temperature affects the number of cricket chirps per minute, then a cricket will chirp more frequently in warmer temperatures than in cooler temperatures because crickets are more active in a warmer environment American Biology Teacher, 37, 5, 300-302, May 75.
