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...

Touch screens are becoming more common, but how do they work? The simulation shows the electric potential versus system charge as scholars alter three variables. The schematic of the capacitance demonstrates the set up as each variable...

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...

In 1820, Hans Christian Orstead discovered the link between electricity and magnetism, which allows us to measure current and voltage. The simulation allows scholars to observe the inner workings of an ammeter and voltmeter as they...

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...
