Students investigate the concept of velocity and apply it to the velocity of sound and measure the velocity of sound by measuring the echoes produced in a tube. They show their calculation of time and speed, and then conclude that sound does have a speed and it is measurable. Finally, students determine a speed of sound. Full Review »
