Light & Sound Vocabulary
Name and use vocabulary for how light and sound behave — light source, transparent, translucent, opaque, shadow, reflect, vibration, pitch, volume — and apply these terms correctly when describing observations about how light travels and how sounds are made and changed
Lesson
Set out your lesson
“Light & Sound Vocabulary means naming light and sound words like light source, opaque, shadow, vibration, pitch, and volume. We will practise once together, then check a fresh example.”
Bring to the table
- Word cards: light source, transparent, opaque, shadow, vibration, pitch, volume
- Simple torch/object demo (optional)
Extra for the adult
Worked example. A lamp is a light source. Opaque blocks light and can make a shadow. Sound starts with vibration. Pitch and volume can change.
Optional challenge. For Light & Sound Vocabulary, add vibration or pitch.
What to notice. Keep one parent note: words matched; support used. This session samples vocabulary, not mastery of waves.

Check understanding
- Correctly classify a set of materials as transparent, translucent, or opaque and explain each term
- Explain what causes a shadow using the words 'opaque' and 'light source' correctly
- Describe what changes the pitch or volume of a sound using vibration vocabulary
“If you held up a piece of frosted glass, could your child say whether it's transparent, translucent, or opaque — and explain what that word means?”
