Control group:
The crickets that are not exposed to heat.

Experimental control group:
The crickets that are exposed to heat.

Independent variable:
The temperature each group of crickets is exposed to.

Dependent variable:
The amount of times the crickets chirp while exposed to different temperatures.

Hypothesis
If the crickets are out in a warmer climate, then they will chirp more because people usually hear crickets in the summer when it is hot
