Step Into Science
Free, fully interactive science worlds — right in your browser. No download, no account, all ages. Explore, experiment, and learn by doing.
Singularity — Black Hole Simulator
🌌 Grow from cosmic dust to the centre of the universe • Free • No Account
Begin as a single mote of dust and drive through real-time gravity, swallowing everything smaller than you. Snowball through asteroids, real-textured planets, and blazing stars, collapse into a black hole, and devour the galaxy — with a real astronomy data card on every object you eat (yes, including the actual red Tesla SpaceX launched into space).
Marine Biology Simulator
🤿 Become an ocean scientist on a living coral reef • Free for Everyone • No Account
Dive a vibrant 3D reef teeming with real species — from clownfish and sea turtles to whale sharks, orcas, and a prowling megalodon. Scan creatures to build a living encyclopedia, collect samples and analyze them in the lab, clean up the reef to restore its health, and follow a guided campaign of missions that earns you the rank of Master Naturalist.
Alchemy Simulator
🧙 Brew real chemistry in a candlelit wizard's tower • Free for Everyone • No Account
Step into an alchemist's workshop lit by hearth-fire and moonlight. Gather ingredients from the shelves, brew them in the iron cauldron, and discover transmutations powered by real chemistry — alloys, acids, pigments, even plastic made from milk. Fill your grimoire, rise from Apprentice to Grand Alchemist, and earn the Philosopher's Stone — then learn the truth about turning lead into gold.
Research Lab Simulator
⚖️ Real quantitative chemistry — weighed in grams • Free for Everyone • No Account
A working research lab with every real element (118) and hundreds of real compounds — solids, liquids, gases and solutions. Weigh reagents on the digital balance, react them in the flask, and get true stoichiometric results: moles, limiting reagents, actual yields in grams, and what's left over — straight from the balanced equation, like a real chemist.
Tornado Simulator — Stormrunner
⛈️ YOU are the tornado — survive the 50-mile swath • Free for Everyone • No Account
Spawn as a funnel cloud inside a supercell and ride a 50-mile storm corridor. Follow warm inflow, convert wind shear, dodge dry air and cold outflow, and grow from funnel to EF5 — leaving a real damage path through farms, towns, forests and industry. When the atmosphere starves you, feed on destruction to stay alive. School-safe: every person and animal evacuates to shelter, always.
Bot Arena — Battle Robotics Simulator
⚔️ Build your battle robot, then survive the cage • Free for Everyone • No Account
Pick from a 20-bot roster — wedges, spinners, flippers, hammers, walkers, even a humanoid mech — then customize paint, weapons, armor and mobility with real engineering tradeoffs. Enter the rocket-glass combat cage against AI opponents with personalities, where floor saws, hammer posts, the pit, shock panels and conveyor beltsare as dangerous as the other robot. Win by knockout, flip, pit-drop, or judges' decision.
Tree Masters — Arborist Simulator
🪓 Climb, prune & fell like a pro • Free for Everyone • No Account
Run a real tree-care career. Identify the species, climb up and diagnose the defects — deadwood, cracks, codominant stems, root rot — then prescribe the correct ANSI A300 plan. Make proper collar cuts with the 3-cut method, respect the 25% rule, and take whole trees down with a real notch & hinge. Graded like an ISA certification exam, from backyards to storm response to champion old-growth.
