Learning journey

Your child is discovering how electricity works — building simple circuits with batteries and bulbs, understanding how switches control electrical flow, and learning which materials conduct electricity and which don't.

Evidence of understanding

  • Predict whether a lamp will light by tracing the circuit for a complete loop
  • Explain that a gap anywhere in the circuit breaks the loop and the bulb won't light
  • Identify the fault in a non-working circuit (e.g. loose wire, missing connection)

Assessment prompt

If Will the bulb light up? looks at a circuit diagram, can they tell you whether the bulb will light up or not, based on whether there's a complete loop?
