Electricity is a big mystery to people.  They hear it is dangerous, they know that they can flip on a switch to get it, but very few know what happens once that switch or circuit is now open.  What is Ohm’s law?  How does a switch work?  How about you create a game that allows you to see everything work?  Do not sleep on introducing the equations of Ohm’s law and have students use them to understand what is going on in that circuit.
