Grades 6-860-75 minSource: Creative Dad Company

Teams choreograph a mock laser and light show, using geometry and timing to sync beams with music without ever pointing a real laser at anyone.

Setup

Print or hand-copy the essential prompt for Concert Laser-Show Simulator, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Listen to a music clip and predict where beams of light should hit and when they should change to match the beat.
  2. Set up flashlights, mirrors, and colored filters to create a simulated laser pattern in a darkened space.
  3. Run the show against the music, find the timing drifts out of sync partway through, and adjust the beam angles or cue timing to fix it.
  4. Perform the finished light show for an audience, explaining the geometry behind the beam angles.

Done when: The group has completed Concert Laser-Show Simulator when it can perform the finished light show for an audience, explaining the geometry behind the beam angles and point to the observation, measurement, comparison, or trial that supports its conclusion.
