Sound Travels Through Materials
Recognise that vibrations from sounds travel through a medium (solid, liquid, or gas) to the ear

Teaching Table
Set out your lesson
Trace sound vibrations through a material medium.
Ask for an example of one prerequisite idea; revisit if needed. Historical graph coverage does not establish this learner’s readiness.
Use cards; optional cup telephone only with adult-made safe holes and short string held away from necks and walkways. Do not submerge heads or test loud sounds.
Use supplied stage sheets on screen or scrap paper; keep adult keys separate.
Use the fictional scenarios. Passing is allowed. Do not ask for private money amounts, account details, family conflict, identity or health information. Keep only minimal local learning notes.
Supplied data are explicitly practice data, not observations. Record only what is actually attempted; absent equipment, consent, partner or repeated observations means that part remains pending.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Supplied transmission model; no actual telephone or underwater hearing observations claimed.

Check understanding
- Explain that sound vibrations need a material (medium) to travel through — they can't travel in a vacuum
- Give examples of sound travelling through different media: air, water, solid objects
- Describe how a string telephone works: voice vibrates the cup, vibrations travel along the string to the other cup
“Can your child explain why you can hear someone talking through a wall, and why sound travels through water when you're swimming underwater?”
