Giant Ionic Lattice Simulation — Description The simulation shows a 5×4×4 NaCl lattice of 80 ions rendered in 3D using Three.js. Na⁺ ions appear purple and smaller, Cl⁻ ions appear green and larger, reflecting their real relative ionic radii. Yellow lines represent the electrostatic attraction between each Na⁺ and its six adjacent Cl⁻ neighbours. Students […]

Nuclear fission Simulation — Description Simulation This interactive HTML5 + Canvas simulation visualizes the deuterium-tritium (D-T) nuclear fusion process — the most promising reaction for practical fusion power on Earth. It is divided into three clearly labeled tabs: The physics is accurate and fact-checked (D-T cross-section behavior, energy partitioning, ITER-like parameters, no chain reaction, stable

Nuclear fission Simulation — Description Simulation Three tabs showing nuclear fission at increasing scale: Single Fission — a ²³⁵U nucleus absorbs a slow neutron, becomes excited [²³⁶U]*, then splits into ⁹²Kr + ¹⁴¹Ba + 3 neutrons + ~200 MeV. Watch the shockwave, fragment separation, and neutrons streaming out. Chain Reaction — each fission triggers more,

Simulation of Background radiation Simulation Overview A Geiger counter simulator showing background radiation in real time. Six toggleable sources fill the detector chamber with colour-coded particle tracks — each type rendered physically correctly: The live CPM counter updates every 0.5 seconds. The rolling graph shows count rate over 2 minutes. The contribution bar shows each

Radioactive Decay Simulation — Description Half-Life Simulation 64 radioactive atoms are displayed in a grid. Each atom glows and shakes while unstable. When it decays, it flashes and dims. The live graph on the right plots actual decay data against the theoretical curve N(t) = N₀ · e^(−λt) in real time. Choose from five AQA
