Communication with Light & Sound
Design and build a device that uses light or sound to solve the problem of communicating over a distance
Suggested ages 6–7
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
- Design a device that uses light or sound to communicate over a distance (e.g. string telephone, torch signals)
- Build and test the device, identifying what works and what could be improved
- Explain how the device uses properties of light or sound to transmit information
Assessment prompt
Could Communication with Light & Sound design a simple device — like a string telephone or a mirror signalling system — to send a message to someone far away?
