Electricity: Foundations
From static sparks to your first circuits — the KS3 foundations of electricity.
Start at the very beginning: what charge is, how current flows, how to read and build circuits, and how electricity reaches your home safely. Short, visual lessons with quick checks along the way.
Charge and static electricity
Where electricity begins: charge, and what happens when it can't flow.
Current and simple circuits
Get charge moving, then read and build your first circuits.
Voltage, resistance and circuit rules
What pushes the current, what slows it, and how it shares out.
Energy, safety and the grid
Storing energy, staying safe, and how electricity reaches you.
