Tilt-Switch Light Box
Tilt-Switch Light Box https://drive.google.com/drive/folders/1D74YT7uWJId80twUfnks8ow-KHCMck1H Days: 2 Mode: Individual Take-home: Working light box
Teaching & key ideas
Key concepts: Closed circuits, LEDs, polarity, switches/sensors, troubleshooting.
Hook: Tilt a finished box so the light turns on/off without a visible pushbutton.
Test / evidence: LED lights reliably in the intended orientation and turns off when tilted back.
Variables to change: Sensor orientation; LED placement; light diffusion.
Lesson flow
Lesson plan:
Day 1: Circuit demo → wire LED + tilt sensor → test orientation
Day 2: Build into box → troubleshoot → add artwork/light diffusion
Safety / cleanup:
Prefer an enclosed AA battery pack for take-home. No loose coin/button cells; if an LR44 holder cannot be securely enclosed, the battery remains at school. Teacher inspects every connection and battery enclosure.
