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
Typical age: 9–11 years
“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?”
