Nature’s Thermometer
Did you know that crickets can tell temperature. Try this experiment and see.
Materials:
1. A evening when you can hear crickets chirping.
2. A stop watch or timer
3. A calculator (optional)
Procedure:
1. Count the number of cricket chirps per minute (try to count the chirps from one cricket)
2. Subtract 40. Divide that number by 4. Add 50. This will give you the temperature +/- 5 degrees F.
What’s happening?
Crickets chirp faster in warm weather. Someone really smart figured out a formula for matching the number of chirps with temperature.
