Nano particles Simulation Description Three interactive 3D modes, all orbitable by drag, zoomable by scroll/pinch, with full SEND accessibility. ◆ Nanoparticle (Gold Au) A ~115-atom gold FCC metal crystal cluster rendered with per-instance colouring: bright gold on the outer surface fading to deeper amber in the interior, reflecting that surface atoms are chemically distinct from […]

Simulation Description Diamond, Graphite & Graphene — Interactive 3D Carbon Allotropes · Giant Covalent Structures This simulation lets students explore all three carbon allotropes in 3D, switching between them to compare bonding, geometry, and electron behaviour directly. Each mode has its own camera angle chosen to reveal the structure’s key feature — diamond at a

Metal Alloys Simulation — Description The simulation shows a 3D hexagonal close-packed metallic lattice (6 rows × 9 columns × 3 deep) that students can orbit, zoom, and interrogate by hovering individual atoms. Three controls drive the core chemistry: ⚗ Alloy transitions the lattice from pure metal to alloy — substitutional atoms grow in at

Polymer and Monomer Simulation — Description The simulation Three parallel poly(ethene) chains run side by side in 3D space. Carbon atoms (grey-blue spheres) form the zigzag backbone; hydrogen atoms (smaller cream spheres) branch off each carbon. Yellow lines between the chains represent weak van der Waals forces — the intermolecular forces that hold chains together

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
