Assume that the supply of low-skilled workers is fairly elastic, but the employers demand for such workers is fairly inelastic. Have a thermometer set up so that it is measuring the outdoor temperature in the area. Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. While it's between 55 and 100 degrees F outside (and keeping in mind that evenings are usually best for hearing crickets chirping) go to the area where crickets are. If you were to do this experiment the crickets in the warmer temperature would chirp more because the heat would have affected them in some way. Will crickets chirp more if the temperature is warmer? The cooler the temperature, the slower the reaction rate, and the less frequent thechirps. That way you reduce how varying conditions, like rain or drought, might affect cricket chirps. Chirping requires a lot of energy, hence, crickets automatically stop doing that if temperature is ~59F (~15C) or below. For an advanced challenge, compare which equation gives the best fit with your calculated temperature data: The linear Farmers' Almanac equations (used in this activity) or the Arrhenius equation, which contains an exponential factor. Null Hypothesis - Crickets will not chirp more or less dependent on the temperature . As wild as it sounds, this is one piece of weather folklore that's actually true!
