EASY SOUND WAVES ACTIVITY FOR KIDS

SOUND AND VIBRATIONS

First, what is sound? Sound is a vibration that travels as a wave, through a medium such as a gas, liquid or solid. As the particles vibrate, they move nearby particles, moving the sound further away.

Can you make the sprinkles dance through using sound and vibrations? When you play music loudly enough and at the right pitch, it generates sound waves. Those sound waves will make the plastic wrap vibrate.

Depending on the size and shape of the container you use for this sounds waves activity, you may have to adjust the volume and placement of the speaker to get the sprinkles to dance.

If the pitch of the music is too high or too low, the sprinkles may not move at all. If the pitch is “just right,” you will find they may bounce around like crazy or even fall off the plastic.

Sounds are higher or lower in pitch depending on how much the sound waves vibrate. Low pitch sounds have slower vibrations and high pitched sounds have much faster vibrations. The way an object responds to sounds of different pitches is called its frequency response.
