Simulation description Mass Changes in Reactions is an interactive 3D Three.js simulation for AQA GCSE Chemistry, covering conservation of mass. A conical flask sits on a digital mass balance, tared to zero. Pupils choose one of two open system reactions. Oxidation (2Mg + O₂ → 2MgO). Magnesium ribbon burns with an intense white flame and […]

Radioactive Decay Simulation — Description Here is a draft for your blog post, formatted to be engaging, clean, and ready to publish. Exploring the Atomic Glue: A Guide to the Strong Nuclear Force Simulation Have you ever wondered how an atom’s nucleus stays together? Protons are positively charged, and basic physics tells us that like

Critical Angle is an interactive HTML5 Canvas simulation demonstrating the critical angle and total internal reflection for GCSE Physics (Waves topic, 4.6.2). Light travels upward from a glass block (n = 1.50) toward the boundary with air. A single draggable angle slider lets pupils vary the angle of incidence in the glass and watch the

Refraction and Reflection – Ray Diagrams Simulation Description A light ray travels down through air and crosses a boundary into a denser medium, bending toward the normal as it does. The simulation draws the incident ray (blue), the refracted ray (its colour matching the chosen medium), and a faint reflected ray (green), with angle arcs

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
