For example: (1) crickets generally do not sing at temperatures below 55 F or above 100 F, (2) some crickets do not chirp in discrete bursts, they utter a more continuous trill, (3) chirp rate is affected by other factors such as the cricket's age, mating success, hunger, and with competition from nearby males. Add 40 to the number of chirps you counted. Back in 1897, a scientist named Amos Dolbearpublished an article The Cricket as a Thermometer that noted the correlation between the ambient temperature and the rate atwhichcricketschirp. Average your results by adding up the number of chirps and dividing by five. Just plug in the number of chirps and it will convert the number to a temperature in degrees Fahrenheit, Celsius, or even in Kelvin (you do you!). Bring astopwatch (a mobile phone has one).
