Wave Behaviour Vocabulary
Use technical vocabulary for wave behaviour — refraction, absorption, reflection, scattering, amplitude, frequency, wavelength, echo, spectrum, angle of incidence, angle of reflection — and apply these when explaining how light and sound travel and interact with different materials
Lesson
Set out your lesson
“Wave Behaviour Vocabulary means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A torch or phone light and a blank wall OR a rubber band / ruler for sound
- Paper for notes
Extra for the adult
Worked example. Move the torch closer: the shadow gets bigger. Distance caused the change.
Optional challenge. For Wave Behaviour Vocabulary, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Wave Behaviour Vocabulary, not mastery.

Wave Behaviour Vocabulary means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A torch or phone light and a blank wall OR a rubber band / ruler for sound; Paper for notes. 1. Say the goal of Wave Behaviour Vocabulary in plain words once. 2. Adult makes one light or sound change (shadow size, or pitch by tightening) and names what changed. 3. Child makes three controlled changes and records what they see or hear. 4. Fresh check: one fresh cause-and-effect observation. Record and stop. Done: three recorded light/sound changes with a cause each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Use 'refraction' correctly to explain why a straw appears bent in a glass of water
- Distinguish 'reflection' from 'refraction' using the correct definitions
- Explain what an echo is using the vocabulary of sound reflection correctly
“Can your child explain why a straw looks bent in a glass of water using a proper science word — or tell you what's actually happening when you hear an echo?”
