Patterns & Codes for Information

CONCEPTUAL

Science›Waves, Light & Sound|Ages 9—10|ID: mt_n5_Jt4ExUd

Generate and compare multiple solutions that use patterns to transfer information, such as codes and signals

Mastery Evidence

Describe at least two systems that use patterns of light or sound to transfer information (e.g. Morse code, semaphore, drum signals)
Design a simple code using light or sound patterns to send a message
Compare the advantages and disadvantages of different information transfer methods

Assessment Prompt

“Can [child] come up with different ways to send a secret message using patterns of light or sound, like Morse code or drum beats?”
