An experiment was done to determine the effect that increasing the temperature would have on the rate at which a cricket
chirps. Two groups were established. Group A received 5mL of water, 2g of food, and was kept at 10° Celsius. Group B
received 5mL of water, 2g of food, and the temperature was increased to 21° Celsius.
