How switches work
Recognise that a switch opens and closes a circuit, controlling whether a lamp lights or a buzzer sounds

Teaching Table
Set out your lesson
Explain how a break or connection controls a simple series circuit.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Work from the supplied circuit models. Physical extension only with an adult-supervised low-voltage educational kit already available, used exactly as its instructions specify. Never open household switches, use mains electricity, or connect battery terminals directly. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Recognise that a switch opens and closes a circuit, controlling whether a lamp lights or a buzzer sounds
Physical switch addition/demonstration is conditional; household wiring is not modelled as safe learner work.
- partial: Explain that a closed switch completes the circuit (current flows) and an open switch breaks it (current stops)
Physical switch addition/demonstration is conditional; household wiring is not modelled as safe learner work.
- partial: Demonstrate adding a switch to a circuit and using it to control a bulb or buzzer
Physical switch addition/demonstration is conditional; household wiring is not modelled as safe learner work.
- partial: Relate the switch concept to everyday switches in the home
Physical switch addition/demonstration is conditional; household wiring is not modelled as safe learner work.
- partial: Can {{name}} explain what happens inside the wall when they flip a light switch — that it completes or breaks the electrical loop?
