His work, titled The Cricket as a Thermometer was published in 1897. If an experiment is conducted to see how temperature affects the number of cricket chirps per minute, then a cricket will chirp more frequently in warmer temperatures than in cooler temperatures because crickets are more active in a warmer environment. Crickets chirp through stridulation: the process of making sound by rubbing two body parts together. 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.
