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.
