Lessons
12 totalConservation of energy
Energy can't be created or destroyed — only transformed.
Energy efficiency
Useful output vs wasted energy — and how to improve it.
Types of energy sources
Where humanity gets its energy — and the trade-offs.
Generating electrical energy
How spinning magnets and moving charges create electricity.
Renewable vs non-renewable energy
Evaluate the options for powering our future.
Electric circuits — components and diagrams
Build a circuit, draw it correctly, and understand each part.
Series and parallel circuits
One path or many — and why it matters.
Ohm's law — voltage, current and resistance
V = IR: the equation that explains electric circuits.
Energy transformed over time
Power — the rate at which energy is used.
Energy star ratings
