Series and parallel circuits

This online resource give details on a teacher demonstration where students are introduced to electrical circuits through a set of Christmas lights.

The resource then details how student groups can then build simple circuits using batteries, wires and light bulbs.

The students can then examine how electricity is conducted through a light bulb using a battery as a power source. Students can also observe the differences between series and parallel circuits by building each type and relate the Christmas tree lights to the circuits they have built.

Circuit world

This online resource allows students to build virtual electrical circuits.

The components of the circuits can be either fun characters, pictures of components, or the proper engineering symbols.

Students can change the type of symbols being used at any time.

A worksheet has also been provided to get the most out of this site.

Please note that this is not a good site for series and parallel circuits as it can reinforce the misconception that attaching a greater load to a circuit means more current will flow.

Building an electric motor

This online resource is a guide to building a basic electrical motor or generator.

The resource uses simple equipment and has a series of instructions with photos. 

It should take approximately 45–60 minutes. It is a good curriculum extension when investigating factors that affect the transfer of energy through an electric circuit.

The site works well on iPads.
