However, problems with putting this theory into practice abound. The number of chirps a cricket makes relates to the temperature. Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. At very low temperatures, less energy is available and the rate of chirping is slower. 2 Will crickets chirp if the temperature is warmer hypothesis? 1. Place heating pad under the 6thbox and set heat setting to 15oC. As the temperature rises, it becomes easier to reach a certain activation or threshold energy, and chemical reactions, like the ones that allow a cricket to chirp, can occur more rapidly. As temperature rises, it becomes easier for them to chirp, whereas when temperature falls, reaction rates slow, causing a cricket's chirp to also diminish.
