Set out your lesson
“If your child 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?”
Full guide and materials
- Activity. Identify whether or not a lamp will light in a simple series circuit, based on whether the lamp is part of a complete loop with a battery
What to notice. 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)
