Communication with Light & Sound

PROCEDURAL

Science›Waves, Light & Sound|Ages 6—7|ID: mt_ZL9qVVnpwN

Design and build a device that uses light or sound to solve the problem of communicating over a distance

Mastery Evidence

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

“Could [child] design a simple device — like a string telephone or a mirror signalling system — to send a message to someone far away?”
