__ Cricket Experiment __ (Apply the topics and terms of scientific inquiry by answering the following questions.) (Copy the numbers and terms. Then answer the questions. Locations of answers are provided.)

1. Question: (What question was posed to get the experiment started?) (1st paragraph, page 19)

2. Hypothesis: (What hypothesis was presented?) (4th paragraph, page 19))

3. Controlled Variables: (What are the three variables that were kept the same?) (2nd paragraph, page 20)

4. Manipulated Variable: (What is the manipulated variable?) (3rd paragraph, page 20)

5. Responding Variable: (What is the responding variable?) (3rd paragraph, page 20)

6. Control for comparison: (What is a possible control for this experiment?) (4th paragraph, page 20)

7. Interpretation of the data: (What is the interpretation of the data? Cite a pattern or trend in the data) (1st paragraph, p. 21)

8. Conclusion: (Does the data support the hypothesis or not? Cite the data that indicates why or why not?) (2nd paragraph)

Answers 1. Question: Might crickets chirp more when it is hot. 2. Hypothesis: Chirping increases as temperature increases. (Both variables.) 3. Controlled variables: container size, thermometer type, and cricket species 4. Manipulated variables: temperature 5. Responding variable: number of chirps per minute 6. Control for Comparison: Three crickets groups experiencing three different temperatures 7. Interpretation: 83 chirps/m at 15C, 127 chirps/m at 20C, and 168 chirps/m at 25C shows that chirping increased with temperature. Chirping increased about 8 chirps/m for each degree C. The graph has a positive slope. 8. The hypothesis is supported by the data. The amount of chirping increases from 83 chirps/m to 168 chirps/m with an increase of 10C. This is 10 degree increase doubles the amount of chirping per minute.
