About This Lesson
Dolbear theorized that the temperature can be computed by counting the number of times a cricket chirps in 15 seconds, and then adding 40 for the temperature in degrees Fahrenheit. For example, if a cricket chirped 20 times in 15 seconds, Dolbear theorized that would mean that the outside temperature was 60 degrees Fahrenheit. Aligned to Common Core State Standard: 8.EE.6
