Understand electricity through the same experiments that early scientists used. Wind a coil of wire. Suspend a bar magnet in it. Charge the coil with a battery to spin the magnet. Test polarity. Discover the origins of motors and Morse Code.

Switch on understanding. Construct a house with a power source. Connect positive and negative test bars with contact points and switches for you to test different configurations of incandescent and LED lights. Test it. Understand series and parallel circuits. Test them. Rearrange them. Test again. Then experiment with other challenges.... Lessons in electricity and thinking.

Study motion by building a spiral track for a marble to follow.
