Electricity

Understand electricity through the same experiments that early scientists used. Create an electromagnet and learn about how they work, what they are used for and how so many things we use require electromagnets to function. Wind a coil of wire and suspend a bar magnet in it. Charge the coil with a battery to spin the magnet and test polarity. Discover the origins of motors and test out the strength of your electromagnet.
 

A battery's current flows in one direction. The clever arrangement of switches can reverse the direction of flow through a motor. Construct a controller with a battery, motor, and ultralight buggy that can go forward or backward. Learn wiring logic, precision, and troubleshooting. Test and play, experiment and investigate.
 

Electricity can be hard to understand. Sometimes it is easier to understand something by building it. Construct a simple circuit in the form of a house. Assemble a battery pack to power your house. Connect it in a loop with switches and lights (incandescent and LED).
