Does the frequency at which crickets chirp change with environmental temperature?


 * INCLUDE ALL OF THE FOLLOWING WITH YOUR EXPERIMENTAL DESIGN: **


 * [remember it must be a controlled experiment] **


 * 1. A hypothesis **
 * The frequency at which crickets chirp change with the environment's temperature. **


 * 2. Explain how to set up the experiment **


 * ** brainstorm a list of all the variables that must be kept constant during the experiment **
 * ** species of crickets **
 * ** season **
 * ** gender of crickets **
 * **time of day**
 * **weather conditions (ex: rain, snow, sunny)**
 * ** include identification of the independent variable **
 * ** The independent variable is the weather conditions **
 * ** the dependent variable **
 * ** frequency of crickets chirping **
 * ** identify the control group **
 * ** crickets in moderate weather conditions (not freezing, not very hot) **
 * ** identify the experimental group(s) **
 * ** crickets in very hot weather conditions **
 * ** crickets in freezing weather conditions **

Fred's friend Bob told him that the frequency of which crickets chirp change with the environmental temperatures. Fred decided to do a experiment, to try and find the results of Bob's hypothesis. He placed 50 crickets in a climate that has warm temperatures, and 50 crickets in a climate with cool temperatures. Fred then recorded how many times he heard a chip in each weather condition of five minutes.
 * 3. Provide enough details for someone else to set up your experiment **
