Measuring the Speed of Sound with an Echo

Students will first predict the speed of sound in the air of their classroom using a simple relationship accounting for temperature. Students will measure the time it takes a short pulse of sound to travel the length of a tube, reflect off the closed end, and return. Using this measurement, they will calculate the speed of sound and compare it to their prediction.
