Setup
Gather flashlights, signal-code cards, floor markers and clear a small work surface. Read the Firefly Signal School mission aloud, then place the supplies where children can choose and compare them safely.
Activity
- Talk about how real fireflies flash light patterns to talk to each other in the dark.
- Build simple flash patterns using a flashlight, like two short blinks or one long glow, and write them down as a code.
- Send a pattern to a partner across the dark room, discovering they misread a pattern that blended two signals together, then add a pause between flashes to fix it.
- Hold a Firefly School show where each student sends and correctly reads a message using only light patterns.
Done when: Children complete the core mission and a Firefly School show where each student sends and correctly reads a message using only light patterns.
