These instructions assume some graph-making experience, so If you arent very familiar with making graphs and plotting data, make sure to work with someone who can help you. Dolbear made a detailed study of cricket chirp rates based on the temperature of the crickets environment and came up with the cricket chirping temperature formula known as Dolbears Law: T = 50 + (N - 40) / 4 Where: T = temperature in degrees Fahrenheit. The tone of the chirping depends upon the distance between thewrinkles. As crickets warm, they can rub their wings together faster, which is how male crickets make the nightly repetitive chirp they use to attract mates.
