Drawings That Light Up


Here are 2 very graphic impressions that drive electricity.

  • A police car  : the headlights of the car come on when you put the batteries.
  • A labyrinth  : same principle as the previous one however we left a few whites, the circuit is broken. You can "fix" it with your pencil (the mine is graphite, a conductive material).

After the activity, add a piece of tape to fix the batteries, and you get a bright poster for your room.

What will you learn?

  • conductive / non-conductive materials
  • LEDs, polarity, anode, cathode
  • the operation of the switch
