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
Suggested ages 6–8
Learning journey
Your child is investigating light and sound — discovering how we see objects, experimenting with transparent and opaque materials, and learning how vibrations create sound.
Evidence of 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
Assessment prompt
If you held up a piece of frosted glass, could Light & Sound Vocabulary say whether it's transparent, translucent, or opaque — and explain what that word means?
