Cricket Thermometers
The sound of crickets chirping is a sure sign of summer, but did you know that it can also tell you how hot it is? Crickets are cold-blooded so when the temperature in the air changes, the cricket’s body temperature changes with it. As the temperature rises, the cricket’s metabolism increases, allowing the process that triggers the chirp-creating muscle contractions to happen more quickly. Frequent chirping is a sure sign that the heat is rising!

To figure out the exact temperature in degrees Fahrenheit, count the number of chirps in 14 seconds and add 40. To get Celsius, count the number of chirps in 25 seconds, divide that by 3, and then add 4.

“If birds fly low, expect rain and a blow”
Do animals tell us when a storm is coming? Birds react to the drop in air pressure before a storm by flying low, and not flying at all an hour or so before the storm hits. Other animals behave strangely before a storm too—bats fly low and insects stay close to the ground, while wolves howl because the pressure change hurts their ears.
