You can build and simulate circuits right on your phone or tablet, animate and understand how they work, check homework and test your designs.Learn about electricity circuits as you experiment with batteries, voltages and light bulbs in this great electricity activity. Wiring them in different ways can result in surprising outcomes. Try changing the battery in the circuit to make the light bulb glow brighter, increasing the voltage will have this effect. Check your model and see how it looks as a circuit diagram. Enjoy the variety of challenges that involve changing the circuit, moving switches, replacing bulbs, changing the battery volts and adding longer wires. Kids will have fun with this interactive electricity game.
