Date / Time / ChirpingWhat is the problem? ______
______
Collect Information
How do crickets chirp? ______

Formulate a Hypothesis and Perform the Experiment
1. First choose wind speed as your independent variable. Then run the experiment with three different wind speed values (between 0 and 7). Fill in the data table.
Wind Speed / # of Chirps in 1 minDoes it seem the number of chirps depends on the wind speed? ______
2. Next choose the number of crickets nearby as your independent variable. Then run the experiment with three different values for the number of crickets nearby (between 0 and 20). Fill in the data table.
# of Crickets Nearby / # of Chirps in 1 minDoes it seem the number of chirps depends on the number of crickets nearby? ______
3. Next choose the humidity as your independent variable. Then run the experiment with three different humidity values (between 10 and 80). Fill in the data table.
Humidity / # of Chirps in 1 minDoes it seem the number of chirps depends on the humidity? ______
4. Next choose the atmospheric pressure as your independent variable. Then run the experiment with three different atmospheric pressure values (between 680 and 790). Fill in the data table.
Atmospheric Pressure / # of Chirps in 1 minDoes it seem the number of chirps depends on the atmospheric pressure? ______
5. Finally choose the air temperature as your independent variable. Then run the experiment with three different air temperature values (between 5 and 45). Fill in the data table.
Air Temperature / # of Chirps in 1 minDoes it seem the number of chirps depends on the air temperature? ______
Draw a conclusion
What is the appropriate conclusion for this experiment?
