Assignment
The first step to completing this online experiment is to define the problem. In this case the question asked is: "Is there a single factor that affects the chirping rate in crickets?" This is where the hypothesis came in:
State your hypothesis:
I think the wind speed and the temperature reason will effect the cricket's chirp rate.
The second step is to complete your data tables. This will help keep any information taken throughout theexperiment organized.

The first table indicates the three events in which the same cricket was encountered.

This second table represents the effect wind speed has on the chirping rate of the cricket.
What are your conclusions?
In this table show me the wind speed can not effect the chirp rate.

Finally, the last table shows our independent variable___temperature_______ in fact, is the cause of the variation of the crickets chirping.
The third step in completing this online experiment, is to state your conclusion.
According to the experimental results, only the temperature effect the chirp rate. When the temperature go up the cricket's chirp rate go up,when the temperature go down the cricket's chirp rate also go down.
