Your Challenge: Figure out what temperature it is outside using cricket chirps

What You Need

  • Timer
  • Counter (optional)

Here's How

Fahrenheit

        1.Using a timer, count the number of cricket chirps you hear in 15 seconds

        2.Then add 40 to that number and you will have the current temperature outside

Celsius

        1.Using a timer, count the number of cricket chirps you hear in 25 seconds

        2.Then divide that number by 3

        3.Then add 4 to the number you got from step 2 and you will have the current temperature outside

How It Works

Just like other insect crickets are cold-blooded. This means their bodies are heated and cooled by the air around them unlike warm-blooded animal like us who regulate their internal body temperature through other processes. When it is warm out crickets bodies heat up giving them more energy. When the amount of energy crickets have increases so does the number of chirps they make. This is why the number of chirps crickets make can be used to measure the current temperature outside.

Fun Facts

  • Only male crickets chirp, they do this by rubbing their wings together not their legs as the common myth suggests

  • Crickets chirp for many reasons included scaring off other male crickets and attracting female crickets

  • While they sound mostly the same to us, different species of crickets all have unique chirping sounds
