String Telephones
In Science this week we made string telephones to explore how sound travels over a distance.
When one person talks into their cup, the cup vibrates. The sound energy of these vibrations passes along the string. The string is a solid, so the particles are very close together, and the vibrations can pass quickly and easily along the string. The vibrations then pass from the string into the second cup, which also vibrates. These vibrations pass through the air particles into the second person's ear, who can then hear the sound of the first person's voice. The sound of the person's voice is louder through the string than it is through the air over the same distance.
We had great fun chatting with each other through our telephones.

Making the string telephone was very fun because I never knew that you could speak that way
