Crickets, Chirps, and Temperatures: Is there a Relationship???

to hear Chirpy sing

 Chirps per min Temperatures 20 89 16 72 18 84 17 81 16 75 15 70 17 82 14 76

 Can you predict the temperature by knowing a crickets chirps per minute output? Use Excel to come up with a mathematical relationship of this data (table and chart.) When you are finished compare it to Eric Sloane's Insect Thermometer (see handout). Does it match up? Is this a linear relationship? Explain. Factoid: Crickets make their chirping sounds by rapidly sliding one wing over the other. The faster they move their wings, the higher the chirping sound that is produced. Scientists have noticed that crickets move their wings faster in warm temperatures than in cold temperatures. Therefore, by listening to the pitch of the chirp of crickets, it is possible to tell the temperature of the air. (See website below and Excel document.)
