According to Science Buddies, the best results are obtained when this experiment is done on a day when the temperature is between 55 and 100 degrees Fahrenheit. 6.
Crickets are most active in warm temperatures, and thrive at about 80 or 90 degrees Fahrenheit. Crickets chirp faster with increasing temperature and slower with decreasing temperatures. Question 5 BACKGROUND RESEARCH: Q: In your scientific experiment, "Is there a single factor affecting the chirping frequency of crickets," you would begin your process of ultimately developing and testing a hypothesis withbackground research. Truancy officers usually do That number plus 40 is a rough estimate of the current The most well known insects that use stridulation to produce sound are the crickets (rub their wings together) and grasshoppers (rub legs or leg and wing), but some ants, wasps, and beetles also use stridulation. This is a fun experiment you or your kids can try, based on one I found on Science Buddies. A cricket as a thermometer? The simplest method is to count the number of chirps in 15 seconds and add 40.

Pick out the chirping sound of a single cricket. Snowy Tree Cricket: T = 50 + (N - 92 / 4.7). This correlation is so reliable that he was able to write a formula connecting ambient temperature to cricket chirp rates now known as Dolbears Law. Average the number of chirps in the 14-second intervals. As the temperature rises, it becomes easier to reach a certain activation or threshold energy, and chemical reactions, like those that occur during the muscle contractions used to produce chirping, can occur more rapidly.
