Immersive 3D Labs
Spin molecules, build atoms, fly through crystals, and take a cell apart. Interactive visualizations that make the abstract concrete — drag to explore.
Chemistry
Interactive Periodic Table
Every element, one tap away
Hover a category to isolate it, click any element for its mass, group, period, and full electron configuration.
3D Molecule Viewer
Rotate real molecules in 3D
Ball-and-stick models of water, methane, benzene and more — see bond angles and molecular shape from every side.
Bohr Atom Builder
Electron shells, element by element
Watch electrons fill shells (2, 8, 18…) across the periodic table and read off valence electrons at a glance.
VSEPR Geometry Lab
Why molecules bend the way they do
Linear, trigonal, tetrahedral, octahedral — see how lone pairs squeeze bond angles in 3D.
Ionic Crystal Lattice
Inside a salt crystal
Fly through the repeating NaCl and CsCl lattices and see how ion size sets the coordination number.
Acid–Base Titration
Chase the equivalence point
Add titrant drop by drop and watch the pH curve climb through the buffer region to the equivalence point.
Kinetic Molecular Theory
Gas particles you can heat & squeeze
Watch gas particles bounce in a box. Turn up temperature or shrink the volume and see pressure climb — PV = nRT, live.
Le Châtelier Equilibrium
Stress a reaction, watch it shift
Heat and cool the N₂O₄ ⇌ 2NO₂ equilibrium and watch the balance of reactants and products shift to counteract the stress.
Biology
DNA Double Helix
Base pairs in 3D
A rotating double helix with color-coded A–T and G–C base pairs and a sugar–phosphate backbone.
Mitosis Animation
Watch a cell divide
Step through prophase to telophase as chromosomes condense, align, and separate into two daughter cells.
3D Animal Cell Explorer
Click any organelle
Orbit a whole animal cell and click the nucleus, mitochondria, ER, Golgi and more to learn what each does.
Neuron Action Potential
Watch a nerve impulse fire
A depolarization wave races down a myelinated axon. Step through resting, depolarization, repolarization and the refractory period.
