Overview

This lesson is designed to help students understand that vibrations are responsible for the sounds we hear. Additionally, they learn that sound vibrations can travel through different mediums. Students experience vibrations using several of their senses: They feel the vibrations in their throat as they hum music, and on their lips as they play their straw kazoos. They see that when a ruler is struck, it vibrates, producing a sound. Drums are also used to show vibrations, as students watch grains of rice bouncing on the surface of the drum after it has been hit, and a laser pointer creates a laser show in the classroom when reflected off a vibrating mirror. Finally, students design a test that uses their sense of hearing to judge the effectiveness of different solids to transmit sound vibrations.

SC15.1.1

Conduct experiments to provide evidence that vibrations of matter can create sound (e.g., striking a tuning fork, plucking a guitar string) and sound can make matter vibrate (e.g., holding a piece of paper near a sound system speaker, touching your throat while speaking).
