Resources to Address This

  • Describing Parallel Circuits (11-14)

    Source - SPT/ El02TL15

    This resource discusses how best to describe the behaviour of parallel circuits in the classroom, and talks about ways of exploring different (but physically equivalent) circuit layouts with students.

  • Circuits from circuit diagrams (11-19)

    Source - Practical physics/ Electric circuits and fields/ Simple electric circuits/ 

    Students of all ages sometimes struggle to relate 2D circuit diagrams with 'real' circuits. Examples and scafolding the skill will help.
