Sounds, Vibrations, and Telephones

Last week we finished discussing our Five Senses (sight, hearing, taste, smell, and touch). Now we move to learning about the physics of sound.

We began with a simple discussion about how we produce sounds. Sounds are made through VIBRATION (a periodic wavelike motion of particles). To demonstrate how vibration happens, we let the children feel their vocal cords.

Once they understood the concept, we then moved on to answer some more questions such as: How come you hear the person better when he is closer to you? How do you hear a person talking from a farther distance? How does a telephone work?

After watching a short video about sounds and telephones we started making a makeshift telephone using papercups and strings. We also had the children decorate their paper cups using colorful origami papers.

The children were very excited to play with their makeshift telephones. During science/art time, I can hear the children saying “Hello! Hello! Can you hear me!”
