Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Choose a sound-travel comic, museum message or cause detective cards.
Show the source, the air and what can vibrate when sound arrives.
Your diagram is a model. What would you still need to see in a real test?
You can pause, stay quiet, use pictures or words, and choose who helps.
Grown-up help
**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.
Source review is complete for this two-week edition. Local suitability and classroom use still need review. Earlier candidate or pending-review words are retained in the original files; full-year coverage, translations and audio are not claimed.
