# Volume & Vibrations

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

Subject: Science · Area: Waves, Light & Sound · Ages 8 to 9

## Ready when they can

- 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

## Lesson: Loud and Quiet: The Size of a Vibration

You already know that every sound starts with something vibrating, moving back and forth very fast. Today you'll find out what decides if that sound comes out loud or quiet. It comes down to size: how far the vibration swings.

*(drawing: A soft tap makes a small vibration. A hard hit makes a big vibration, and a much louder sound.)*

**Example.** Maya has a small drum. When she taps it gently, the drum skin moves just a little and makes a soft sound. When she hits it hard, the drum skin swings much further before it settles down, and the sound comes out loud.

**Tip.** Try it yourself. Hold a ruler flat on a table with one end hanging off the edge. Flick it gently, then flick it hard. Watch how far the end moves each time, and listen to how the sound changes.

**Recap.** Bigger vibrations make louder sounds; smaller vibrations make quieter sounds.
