The Cricket Experiment
It was hypothesized that male crickets¡¯ chirping would increase with exposure to warmer climates. After conducting the experiment, the data collected did not support this hypothesis. According to the recorded data, the male crickets had an average of 90.33 chirps per minute when exposed to room temperature which is 20¢ªC. As a part of our experiment we placed crickets in three different environments in order to observe in which environment male crickets chirp more. We observed that the crickets chirp more in the 20¢ªC but when they were place in extreme temperature which was 0¢ª Celsius or 40¢ª Celsius, there was no chirping at all. There are several variables that could have caused the results of our experiments to come out the way they did: the first variable could be because the crickets were under stress, from constantly being handled and moved around. Another possible explanations for the crickets¡¯ lack of activity could be the fact that most male crickets chirp in effort to court a female, and since there were no females there was no reason to chirp. This website talks about how male chirping to attract females (http://www.msue.msu.edu/msue/imp/mod02/01500542.html).
The calling sound is basically the conspicuous chirping sounds made by males. Past research showed that male field crickets produce three types of acoustic signals: aggressive chirps, which are used in male-male fights; calling songs used to attract females; and courtship song, used directly prior to mating once a female has been located by a male. (Gray 1996) (http://www.msue.msu.edu/msue/imp/mod02/01500542.html). Our poster contains graphs that show how much male crickets chirp in 0¢ªC and 40¢ªC, and also the chirping at 25¢ªC, which was our control group. Our hypothesis was not supported by our experiment, so this shows that the male crickets do not chirp more in warmer weather.
