| Abstract | Students hypothesize about the relationship between the temperature and the number of times a cricket chirps per minute. They listen to a tape of crickets chirping at six different temperatures. (Tape source available in activity.) They count the number of chirps per minute and record and graph the results. Then, they listen to two more crickets chirping at unknown temperatures and record the number of chirps per minute. They use the graph to estimate the temperatures at which the crickets are chirping. They check these values using the equation T = 50 + (N-40)/4, where T represents temperature in degrees Fahrenheit and N represents number of chirps per minute. Finally, students use the graphing calculator to manipulate the data. |
