Grouping: Pairs or individual
Take-home: Working steady-hand circuit game
Key ideas: Electrical circuits, switches/contact, conductivity, mechanical design, ergonomics.
Start with: Complete the circuit by touching a wand hoop to the course wire.
Success check: Game reliably signals contact and can be completed with an appropriately sized hoop.
Try changing: Course shape/length; hoop diameter; wand length.
Preparation: Redesign connections around screw terminals/printed holders instead of tape. Use thicker/easier-to-secure course wire and longer wand wire; shorten course to appropriate difficulty.
Lesson flow: Day 1: Build electrical circuit + secure course wire to base
Day 2: Build wand → test reliability → adjust course/hoop difficulty → play
Safety and cleanup: Low-voltage only; cut wire ends must be rounded/capped; teacher handles difficult bends/cutting.
