Physics and chemistry you can play with.

58 simulations that show what the equations mean, and a chemistry bench where the reagents really react.

Two ways to learn a thing

You can read that light bends. You cannot feel it until you bend some โ€” and keep bending until it stops coming out the other side at all. A simulation hands you the controls and has no wrong answers; a guided experiment hands you a procedure and tells you when you have strayed from it. Intuition and method are not the same skill, and neither one teaches the other.

The chemistry is not scripted

The bench reacts the way the reagents react. A guided experiment only decides the order you meet them in โ€” stray from it and you get real chemistry, plus a sentence telling you what to do instead.

Tied to the chapter you are on

Every piece is attached to the CBSE and ICSE chapters it illustrates, so revising tonight's topic starts with your chapter rather than with a catalogue.
