Nature's Thermometer
Did you know that crickets can tell temperature. Try this experiment and see.
Materials:
- A evening when you can hear crickets chirping.
- A stop watch or timer
- A calculator (optional)
Procedure:
- Count the number of cricket chirps per minute (try to count the chirps from one cricket)
- 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.
