Good Vibrations

On this Quest, you'll discover…

Make things vibrate and listen to the sounds you create.

• Find out that musical instruments make sounds through vibrations.
• Change what is vibrating — a tighter band, a shorter string — and hear the sound go higher or lower.
• Feel a vibration with your fingers while you hear the sound it makes.
• Investigate how different movements of an elastic band cause different sounds.
• Make sounds loud and soft, and describe the difference between volume and pitch.
