Introduction

Do you love to hear the pulsing chirp of crickets as you fall asleep? It is an unmistakable sound. Some people find the sound pleasing and peaceful, but other people find the sound loud and annoying, especially if a cricket happens to get inside a home to escape the cold. However you feel about crickets, their chirps hold a surprising message — they can be used to predict the temperature! In this science activity, you will investigate how the chirps of these tiny creatures can be used to as a kind of thermometer!
