Concentration of Solutions — description & class activity Concentration of Solutions An interactive simulation that teaches how to calculate the concentration of a solution. A live CuSO₄ beaker sits on the left: the liquid’s fill height represents the volume of solution, while the colour depth and the density of dissolved particles represent how concentrated it […]

Atom Economy — Chemistry Interactive Simulation An interactive ClassAdapt simulation teaching atom economy (also searched as “atom efficiency”) for Chemistry. Pupils select from six real reactions and watch the relative formula mass (Mᵣ) of products split into a colour-coded bar — green for the wanted product, red for the waste by-product — with a live

Simulation of piston sliding back and forth inside an engine cylinder This simulation shows a piston sliding back and forth inside an engine cylinder, demonstrating how lubrication reduces friction. A blue arrow on the left shows the driving force pushing the piston; red arrows on the piston show friction resisting its motion each stroke. Three

Simulation of Friction, lubrication using a crate This interactive GCSE Physics simulation shows how lubrication reduces friction between surfaces. As you increase lubrication, the friction force drops, so less energy is transferred to the thermal store (less heating/heat trail) and more of the work done by the push goes into the object’s kinetic energy (it

Mole Lab Challenge — description & class activity What it is A self-contained browser game built around the AQA GCSE Chemistry moles topic. Students play as Dr. Molly, a lab-coated mole who reacts expressively to every answer. Each session runs 10 shuffled multiple-choice questions with instant feedback, a full worked solution after every answer, and
