__Cricket Experiment Facts__:

The scientific process can be used to study the relationship between air temperature and cricket chirping.

Question posed: Does the air temperature affect the chirping of crickets?

“Perhaps crickets chirp more when the temperature is higher."

In this case, your hypothesis would be that cricket chirping increases at higher air temperatures.

Prediction: “If the temperature increases, crickets will chirp more frequently.

Other variables include the kind of crickets, the type of container you tested them in, and the type of thermometer you use.

By keeping all of these variables the same, you will know that any difference in cricket chirping must be due to temperature alone.

In your cricket experiment, the manipulated variable is the air temperature.

The responding variable is the number of cricket chirps.

For the cricket experiment, your would test your control crickets at a constant temperature. That way you can better recognize the effects of increased temperature on chirping.

For example, in this experiment you would need to determine what sounds will count as a single “chirp.”

Figure 12: All the crickets chirped more at 25 C than 20 C or 15 C. Specifically, there were 83 chirps per minute at 15 C and 168 chirps per minute at 25 C. So with a temperature increase of 10 C, the number of chirps per minute doubled.

You concluded that cricket chirping does increase with temperature by citing the data.
