Volume & Vibrations

CONCEPTUAL

Science›Waves, Light & Sound|Ages 8—9|ID: mt__00ZSLnB7p

Find patterns between the volume of a sound and the strength of the vibrations that produced it

Mastery Evidence

Describe the pattern: stronger vibrations (larger movements) produce louder sounds
Demonstrate volume changes by varying the force applied to a sound-making object
Explain volume as how loud or quiet a sound is, determined by the size of vibrations

“Can [child] explain why hitting a drum harder makes a louder sound, and what's happening to the drum skin differently?”
