Hands-on Activity

Bottle Music

Fun Forces
Summary
In this activity, students will make sound three ways: by blowing across the top of a bottle, tapping a glass, and running a finger around the rim of a glass. Students will make predictions and test how the level of water in the bottle/glass affects pitch. Students will “tune” their instruments and play a simple song.
Overview
Topic: Vibrations and Sound
Real World Science Topics:
  • An introduction to how instruments make different sounds.
  • An exploration of the relationship between pitch and the physical characteristics of an instrument.
  • Objective
    By making sounds with bottles and glasses, students will gain an understanding that vibrating objects make sound, the speed of the vibrations determines the pitch of the sound, and the mass of the object determines the speed of the vibrations.

    Activity Difficulty Rating: 2 Each hands-on science activity has been ranked based on difficulty of set up and how difficult they are to perform. The rating scale is from 1 to 5, with 1 being the easiest and 5 being the most complicated.
