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.
Topic: Vibrations and SoundAn introduction to how instruments make different sounds.
An exploration of the relationship between pitch and the physical characteristics of an instrument.
Real World Science Topics:
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.
