- Abstract:
In this activity, students investigate how sound travels through both string and air. First, they analyze the sound waves with a paper cup attached to a string. Then, they combine the string and cup with a partner to model a string telephone. Finally, they are given a design scenario to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the telephone has had on society.
