Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuits load makes it easier to understand how circuit components are connected.
We tour schools offering either single project days, or more extended project work over many weeks and combining multidisciplinary work, mainly to students aged 11 to 14. Through the construction of these cars students learn about electrical circuits and how solar energy functions.
The part of an electrical circuit that is between the electrons starting point and the point where they return to the source is called an electrical circuits "load".
They have been widely used in primary and secondary education (e.g. Duit 1991; de Bóo and Asoko 2000; Asoko and Boo 2001). Analogies are particularly suitable for use in physics (Reiners and Glynn 1995; Kircher and Hauser 1995). They are ideal for teaching principles relating to electricity (Dupin and Johsua 1989, Cosgrove 1995). Students can use analogies to relate with something they are already familiar with and see the similarities between the two systems.
