Physics and chemistry is the secondary subject where the difference between memorising and understanding shows most. You can recite Ohm’s law or that "matter is neither created nor destroyed" and still not know which bulb goes out when a switch opens, or why you need a 2 in front of H₂O to balance a reaction.
Each game on this page is a small lab: you add forces and see which way the object moves, balance a lever with weights at different distances, predict a series or parallel circuit, take a substance from solid to gas and balance reactions by counting atoms on both sides, just like on the whiteboard.
Add the forces and guess which way it moves
Balance the scale: levers and moments
Predict which bulbs light up in the circuit
Solid, liquid or gas by temperature
Tap the right periodic table cell
Adjust the coefficients and balance the reaction
With a summary, examples and a multiple-choice test.
