To determine if cricket chirps can be used to predict the outdoor temperature. Discover world-changing science. When you hear crickets playing their tune, count the number of chirps per intervals of 14 seconds. Grab a stopwatch and a That number plus 40 is a rough estimate of the current temperature in degrees Fahrenheit. The tympanum is located on the front legs of crickets, katydids, and long-horned grasshoppers and on the abdomen of short-horned grasshoppers. A cricket is not able to chirp as frequently at cooler temperatures as it is at warmer temperatures. she thinks that crickets chirp more often when the temperature gets warmers. This should give you the approximate temperature in Fahrenheit. Often scientists take more than one measurement to make sure they get a precise result. She thinks that crickets chirp more often when the temperature gets warmer. %PDF-1.5

These equations all vary slightly, depending upon the species of cricket, but the snowy tree cricket is frequently cited as the most accurate at predicting temperature. In general, only male crickets chirp and the primary reason for the chirp is to attract a mate (much like the flash of a firefly). Throughout the years, follow up studies have been done to come up with slight variations of Dolbears Law based on different species of crickets and katydids. Predation - you let everyone know where you are! These equations are good only in the range of temperatures from 55100 degrees Fahrenheit. It is an unmistakable sound.

Was the temperature based on the cricket's chirps close to the actual outdoor thermometer temperature, and maybe off by only a few degrees F? Do different types of crickets make better thermometers? Is there any connection between the average number of chirps that the cricket made and the outside temperature? Crickets, grasshoppers, katydids, and cicadas all possess hearing organs called tympanum. The early arrival of crickets on the hearth means an early winter.
