Lessons Four subjects
How things really work
Short, hands-on lessons for curious adults. Each takes about 15 minutes: six steps to play with in 3D, then a quick quiz.
Electricity and magnetism 4 lessons
-
01 · Basic electric circuits
What really happens when you flip a light switch: loops, voltage, current and resistance, series and parallel, fuses.
-
02 · Electricity at home
Understand your bill, and what keeps you safe: watts, kilowatt-hours, AC, the wires in a plug, overloads, earth and RCDs.
-
03 · Magnets and magnetic fields
Why magnets attract and repel, the invisible field, why a compass points north, and how a current makes a magnet you can switch off.
-
04 · Motors and generators
How a current in a magnet's field makes a push, how a motor keeps spinning, and how turning a coil makes the electricity in your sockets.
Later in Physics: forces and motion.
Staying safe online coming soon
-
Phishing and suspicious messages
How fake messages try to earn your trust, and how to check one safely without clicking.
-
Passwords and two-step sign-in
Why reused passwords are risky, what a password manager does, and how a second step protects an account.
Later in Cybersecurity: how encryption works.
How computers work coming soon
-
Bits: 0s and 1s
How computers build numbers, words and pictures from simple on/off switches.
-
Logic gates
How simple on/off rules combine to make a computer's decisions.
-
Processor and memory
How a computer follows instructions, and why saved files survive when the power goes off.
Later: how the internet works, and how AI works.
Planned after the first sections
-
Structures
How bridges and towers stand up, and the materials that make them strong.
-
Machines and vehicles
Gears, engines and electric cars: how machines turn energy into useful work.
Engineering's timing follows feedback on the first sections.
