To convert cricket chirps to degrees Fahrenheit, count number of chirps in 14 seconds then add 40 to get temperature. Place thermometer in bottom of box and wait until it reaches 15oC. You record the chirp rate of; Question: 1. Set up a thermometer to measure the outdoor temperature in the area where you will observe the crickets. Grab a stop watch and use the following equation. Make sure you hear some chirping. Have a thermometer set up so that it is measuring the outdoor temperature in the area. To convert cricket chirps to degrees Celsius: For example, if the cricket chirps 30 times in 14 seconds, you would add 40 to the 30 . Now that youve identified your chosen chorus, youll need to make a data table and collect your data. However you feel about crickets, their chirps hold a surprising messagethey can report the temperature! Background At higher temperatures, the energy threshold is easily reached. Why do Crickets make so much noise at night? One tank would be room temperature and the other would be a warmer temperature. Box 520 | Dublin, NH 03444. Information on the Arrhenius equation can be found in the related project idea linked below. They just want to survive as long as possible, so they save their energy. (See which ones more accurate!
