Copy of Evolution_of_Lighting_Circuit_Presentation

- Identify line, neutral, CPC and their uses.

- Build basic battery-powered lighting circuits which Demonstrate switching in neutral and line.

- Explain why neutral switching is unsafe.

- State why switches must be in the line conductor.

​Learners show clear progression from identifying basic conductors to understanding safe switching practices. Knowledge is assessed through targeted questioning and discussion, skills are observed during practical assembly activities, and professional behaviours are reinforced through collaborative tasks. These assessment points ensure learners develop the essential knowledge, skills and behaviours required for safe electrical work.

- Direct instruction + checking prior knowledge. Using quizziz

- Build basic circuit (no switch) Modelling → guided hands-on practice. Mini-discussion + formative questioning.

- Group A: switch in neutral Group B: switch in line Collaborative learning + applied skills practice. Student-led comparison + Socratic questioning.

- Discuss safety and potential difference Quizziz
