Jim was reading about behaviors in animals and saw that scientists have determined you can tell the temperature outside by the number of chirps crickets are emitting. He thought this was interesting and decided to try and find out for himself if this was true. He had read many articles from his magazines and found the information to be factual. Before he began collecting his data, Jim stated that he thought if he collected the number of chirps made by crickets in his yard, then he could determine the temperature.



He checked and found that his local newspaper posted the daily temperature measured each morning at 7:00 a.m. and each evening at 7:00 p.m.



He got five jars and fine cloth he could stretch over the mouths of his jars that would let air in. After Jim had dinner, he collected five male crickets from the field behind his house. He put one cricket in each jar and then set them on his back porch. At 7:00 p.m. in the evening he sat outside and tried to record the number of chirps each cricket made. He realized he was having trouble collecting all his data, so he asked his two younger brothers and 2 younger sisters to help him.  Now they would only have to record the chirps from one cricket each. Every evening they recorded how many chirps the crickets made over a 15 second interval. He recorded this information in a notebook and after two weeks decided to evaluate his data. The formula from the article said to add 40 to the number of chirps in 15 seconds and that would be the temperature.

[b][i][size=3]As Jim is preparing to do the experiment he realizes one variable will be independent or manipulated in the experiment. What will that be? [/size][/i][/b]

[b][i][size=3]Jim also needs to be aware of what variable will respond to the manipulated variable or will be dependent on that variable in the experiment. What variable will respond to the changes during this experiment?[/size][/i][/b]
