Don’t just read it. Move it.
Hundreds of simulations you can drag, tune and break: launch a projectile, balance an equation, trace an algorithm, shift a supply curve. Ideas stick when you have changed them yourself.
No account needed to look around.

Change one thing and watch what follows.
Each interactive puts the controls in your hands. Slide an angle, a rate or a concentration and the graph, the particles or the numbers answer at once.
- Live graphs, diagrams and readouts
- Three levels, from first ideas to first-year university
- Runs in the browser, on a laptop or a tablet
Built for practice, not just watching
Practice you do by hand
You answer by moving something — sorting into bins, putting steps in order, picking on a grid — not by ticking a box.
Organised by subject and area
Browse by subject, then by area — mechanics, calculus, data structures — and by level.
Not tied to one exam board
A projectile is a projectile. The hub serves IGCSE, A Level, IB, AP and SAT learners alike.
Linked from the lessons
Course chapters point to the interactives that go with them.
