Aiden calculated the speed of sound for each of the distances in his "Echo, Echo" lab. He used the formula: distance = 25 hand claps x distance to wall x 2 as his numerator, and divided it by the seconds taken for the 25 hand claps. He read a chart showing the speed of sound for different states of matter. He began the lab "Breaking Waves" by creating a data table and watching the lab video.
