Science you can touch.
A free virtual 3D science lab: build atoms, wire circuits, launch planets and open up a beating heart. Every simulation explains what is happening and how scientists found out, with guided tours and quizzes that tell you why an answer is right. Start with the virtual chemistry lab.
Pick a subject
- ChemistryBuild atoms, pull electrons off them, bond molecules, mix chemicals in a virtual lab and fuse nuclei like the Sun.Open Chemistry
- PhysicsRead a Vernier caliper and screw gauge, time a pendulum, make waves and sound, launch projectiles, wire circuits and bend light through lenses.Open Physics
- BiologyOpen a 3D cell, watch osmosis, enzymes and photosynthesis at work, watch cells divide by mitosis and meiosis, and follow blood through a beating 3D heart.Open Biology
- MathsUnfold 3D shapes into nets, fill them with water to find their volume and slice them into cross-sections.Open Maths
- GeographyFollow a drop of water through the water cycle, from evaporation to rain and back again.Open Geography
Chemistry simulations
- Chemistry FormulasEvery chemistry equation, live: type numbers or pull them from what you built.
Physics simulations
- Physics FormulasEvery physics equation as a calculator: solve for any value, or fill it from your own experiments.
Biology simulations
- Natural SelectionBe the bird: hunt peppered moths on clean and sooty bark and watch the population evolve.
- Biology FormulasEvery biology equation as a calculator: magnification, Hardy–Weinberg, cardiac output and more.
Maths simulations
- Maths FormulasEvery maths formula as a calculator: quadratic formula, Pythagoras, trigonometry, areas, volumes, statistics and interest.
