# Day 8 — Sound can make a receiver vibrate

1. Choose a sound-travel comic, museum message or cause detective cards.

2. Show the source, the air and what can vibrate when sound arrives.

3. Your diagram is a model. What would you still need to see in a real test?

## Pick your setting

- Sound-travel comic
- Museum explainer

**Safe start:** Original short sound text and source–air–receiver illustration; paper labels or blank diagram. No body test, near-ear item, loud sound, rice, powder, balloon, stretched wrap or new instrument is required.

**Use the child’s meaning:** Explains incoming sound energy can cause a receiver to vibrate, distinguishes source vibration/contact/model from receiver effect, with sourced general fact separate from actual observation. Adult checks all actual materials/procedures and records help/evidence route; no attendance or worksheet quota. [Complete text and paper alternatives](../aids/ALTERNATIVES.html) work without a screen or printer. Hold fresh sources and keys away from ordinary practice; these child notes do not reproduce their after records.
