Then the question popped into your mind, “Does air temperature affect the chirping of crickets?” Upon deciding to test this question, you formulated the following hypothesis: “Cricket chirping increases at higher air temperatures.” Your manipulated variable of air temperature and responding variable of amount of chirping were easy to see in this hypothesis. You wanted your experiment to be controlled, so you knew to use crickets of the same size and species. You also knew to use containers of the same size and type; plus the temperature in each would be measured with identical thermometers. Testing the three groups of crickets at about the same time in the evening also occurred to you. (You knew that by keeping all these variables the same it would be more likely that any differences in chirping would be do the air temperature alone.)

For your experiment you decided to test five crickets at 15 degrees C, five crickets at 20 degrees C, and five crickets at 25 degrees C. You recorded your data in a table about the same time one evening. For a moment you wondered how to interpret this data, and then you remembered that graphing data often helps. You used the acronym, “TAILS DRY MIX” to help you graph the data.



1. Properly graph the data. 2. What is the hypothesis? 3. What is the manipulated or independent variable? 4. What is the responding or dependent variable? 5. What are the controlled parameters in this experiment? 6. What is the conclusion of this experiment based on the graph and why?
