Paper cup phone

Students investigate how sound travels through 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 challenge to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the invention of the telephone has had on society.

The classic DIY string telephone with cups is easy to make at home and your kids will have lots of fun talking to each other "long-distance"!

Some of the science experiments for kids include static bulbs, bouncing egg, homemade rainbow, invisible ink, jumping coins, glowing water, homemade rock
