We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Why do some buildings have lightning rods? Scholars explore the movement and attraction of opposing electrical charges through a simulation of a lightning rod. They control the cloud height, charge separation, and if the lightning rod is...

How does a neon light work and does it actually contain the gas neon? An enlightening simulation encourages pupils to play with circuits and neon lights. They control the capacitance, resistance, and color of the bulb, and the simulation...
