Key Problem 1

Factoid: Crickets make their chirping sounds by rapidly sliding one wing over the other. The faster they move their wings, the higher the chirping sound that is produced. Scientists have noticed that crickets move their wings faster in warm temperatures than in cold temperatures. Therefore, by listening to the pitch of the chirp of crickets, it is possible to tell the temperature of the air. The table below givers the recorded pitch (in vibrations per second) of a cricket chirping recorded at 15 different temperatures.

What if someone asked you what the temperature was, but you couldn't use a thermometer?

Could you use the crickets?

In this lesson, you will learn ways to find relationships between two variables (like pitch and temperature) so that for a certain pitch of a cricket chirp you can approximate the temperature.
