String Telephones

We have been learning about how we create sounds and how sounds travel in Science. All sounds are created by vibrations. We used string and cups to create our own string telephones. As we spoke, the vibrations travelled along the string into the other persons ear. We learned that sound travels even better through solids (like the string) than through the air. We discovered that the telephones worked best when the string was tight. Great work team!
