Simulation of Paper chromatography Simulation description This is a 3D paper chromatography simulation for the AQA GCSE Chemistry required practical on separating coloured substances and calculating Rf values. Pupils work through four guided steps. They begin by choosing an ink sample from four options: black ink, green ink, purple ink, or brown food dye. They […]

Simulation of Rate of reaction measurement using syringe and disappearing cross What the simulation does The Rates of Reaction simulation covers the AQA GCSE Chemistry required practical, letting pupils investigate how the concentration of acid affects how fast a reaction goes. It offers two standard methods through tabs at the top. In the disappearing cross

Collision Theory Simulation This is a 2D particle simulation of the reaction A + B → P, modelling the four factors that affect reaction rate through collision theory. Cyan circles (Reactant A) and orange circles (Reactant B) move around a reaction vessel, bouncing off walls and each other. Every time an A particle meets a
