Biologists have determined that the number of chirps some crickets make per minute is related to temperature. They even came up with an equation that is very accurate at predicting it. When crickets chirp 124 chirps per minute it is 68 degrees Fahrenheit. When crickets chirp 172 chirps per minute it is 80 degrees Fahrenheit.
