With your new knowledge of circuits…

  • draw a circuit diagram for a wire loop game…

include an LED light and a buzzer.

  • construct your game!
  • see if any members of your team can complete

your game, without the buzzer sounding or light glowing!

Examples

slide-12
SLIDE 12
  • You must include an LED light bulb and a buzzer in your game.
  • Only one 9V battery can be used.

Rules Materials

You will have the following materials per team:

  • 1 x 9V battery and 1 x battery clip
  • 1 x 9V buzzer
  • 1 LED Light (3mm – 5mm)
  • Thin (bare) copper wire (approx. 60cm per group)
  • Electrical tape
  • Thick cardboard / timber / foam for base
  • Planning sheet / circuit symbols, pens/pencils

Scoring

Groups receive points for:

  • drawing their design prior to construction
  • including both an LED light globe and a buzzer
  • having a functioning game, i.e. the buzzer and/or light

turn on when the wire loop touches the wire path! Groups receive bonus points if… they can complete their own game successfully (without setting off the buzzer and light). Groups receive additional bonus points if… they can complete another team’s game successfully!
