What Makes a Cricket Chirp? Ivy Tech State College Introduction What makes a cricket chirp? It is said that the rate of which a cricket chirps can determine the temperature. After doing virtual experiments, using computer technology, the experiments show that a faster chirping cricket rate is observed as the temperatures rise. Definition of the Problem Crickets chirp at different rates throughout the year and time during the day. What is the one factor that affects the chirping rate in crickets? Will increasing the air temperature make the crickets chirp faster? Each time a cricket was observed, it chirped at a different rate Table 1 Date | Time | Chirp Rate | March 21 | 6am | Slow | June 21 | 2pm | Fast | September 21 | 8 pm | Medium | The question to be asked, is there a single factor that effects chirp rate Formulate the Hypothesis If the air temperature is increased, the crickets will chirp at a faster rate. Testing Using the virtual lab found at www.weymouthhsbiology.wikispaces.com, the experiment will be run to analyze cricket chirp rate. The variables that will be observed are: * # of crickets nearby * Air temperature (25°C) * Atmospheric pressure (760 mm) * Humidity (15%) * Wind speed (2M/SEC) During each of my experiments, I will keep the above constant and vary a single change. This experiment will use the virtual lab and collect and analyze the data. Data collection Atmospheric Pressure | Pressure | Chirps | 700 | 148 | 730 | 148 | 760 | 148 | Wind speed | Wind speed | Chirps | 0 | 148 | 2 | 148 | 4 | 148 | Temperature | Temp | Chirps | 5°C | 4 | 15°C | 76 | 24°C | 141 | 32°C | 198 | 45°C | 292 | Number of crickets #Crickets | Chirps | 0 | 148 | 10 | 148 | 20 | 148 | Percent Humidity | Humidity | Chirps | 10 | 148 | 15 | 148 |
