__Cricket Experiment__/Self Test (Applying the scientific method and its vocabulary.) Answer the following questions on the cricket experiment in your textbook.

1. Posing Question: Choose the question posed to start the cricket experiment. a. Do crickets chirp more early in the night? b. Do crickets chirp more just before dawn? c. Does air temperature affect the chirping of crickets? d. Does container type affect the chirping of crickets? e. Do different cricket species chirp more than others?

2. Hypothesis: Choose the hypothesis used in the cricket experiment. a. cricket chirping increases early in the night b. cricket chirping increases just before dawn c. cricket chirping increases at higher air temperatures d. cricket chirping increases with container size e. some cricket species chirp more than others

3. Controlled variables: What possible controlled variables were given in the cricket experiment. a. species of crickets b. types of containers c. air temperatures d. number of cricket chirps e. both a and b

4. Manipulated variable: Choose the manipulated variable of the cricket experiment. a. species of cricket b. type of container c. air temperature d. number of cricket chirps e. both c and d

5. Responding variable: Choose the responding variable of the cricket experiment. a. species of cricket b. type of container c. air temperature d. number of cricket chirps e. both c and d

6. Control: Choose the control used in the cricket experiment. a. different species of crickets b. crickets kept at a constant temperature c. crickets experiencing three different temperatures d. crickets kept at a constant humidity level e. crickets experiencing three different humidity levels

7. Interpreting the data: At what temperature did the crickets chirp the most? a. 10ºC b. 15ºC c. 20ºC d. 25ºC e. both c and d

8. Conclusion: What does the data show about cricket chirping and the hypothesis? a. Some species of crickets chirped more than other, so the hypothesis is supported. b. Crickets kept at a constant temperature chirped more, so the hypothesis is incorrect. c. Cricket chirping increased as humidity increased, so the hypothesis is supported. d. Cricket chirping increased as air temperature decreased, so the hypothesis is supported. e. Cricket chirping increased as air temperature increased, so the hypothesis is supported.
