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
