How do crickets make their distinctive chirp? They use a process called stridulation, where special body parts are rubbed together to make a noise. Conversely, as the temperature falls, the reaction rates slow, causing the chirping to diminish along with it. 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. Specifically, a formula called the Arrhenius equation describes the activation, or threshold, energy required to make these reactions occur. This affects how quickly these chemical muscle reactions can occur. Crickets, like all insects, are cold-blooded and take on the temperature of their surroundings. How is a cricket's chirp related to 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. However you feel about crickets, their chirps hold a surprising message-they can report the temperature! In this activity, you'll investigate how the chirps of these tiny creatures can be used as a kind of thermometer!
Some people find the sound pleasing and peaceful whereas others find it loud and annoying, especially if a cricket happens to find refuge from the cold inside a home. Do you love to hear the pulsing chirp of crickets as you fall asleep? It is an unmistakable sound.
