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