What the simulation does The simulation covers GCSE Chemistry’s reactivity series across two interactive tabs. Reactions tab — A vertical reactivity ladder runs down the left sidebar, colour-coded from red (very reactive: K, Na) through orange, yellow, green, and purple (unreactive: Ag, Au, Pt). Students click any metal to select it, then choose a reagent […]

This simulation teaches power as the rate of energy transfer / work done. This approach matches the AQA GCSE Physics specification’s recommended emphasis that students understand power as how quickly energy is transferred (or how quickly work is done) and can apply (P = E/t) and (P = W/t) (and, for circuits, (P = IV).

Simulation of Rate of reaction measurement using syringe and inverted cylinder Rate of Reaction Simulation — Description & Class Activity What the Simulation Shows A 3D interactive experiment measuring the volume of CO₂ gas produced when marble chips (calcium carbonate) react with hydrochloric acid: CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l) + CO₂(g) Students can

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

Earth’s gravitational field Simulation Earth’s Gravitational Field is a 3D interactive simulation built on Three.js that lets students explore how gravitational field strength varies with distance from Earth’s centre. It visualises five core concepts through toggleable layers: radial field lines with inward-flowing particles (showing force direction and density), concentric equipotential shells with hover-activated physics data
