An introduction to electric circuits...


Watch the video to find out all about a simple electric circuit.  The battery pushes the electricity along the wires from the positive terminal, through the bulb and back to the negative terminal. This creates a circuit. To turn out the light the circuit needs to be broken by adding a switch. It does not matter where the switch goes as the effect is the same. The bulb glows because electricity flows through the filament. When the bulb gets old the filament breaks and this breaks the circuit.


Once you have watched the video, go to the following website:


Look for a game called 'Circuits' and have a go at completing the challenges and the quiz at the end.


Good luck!
