Explore the State Floor — the East Room, the Blue Room, the Cross Hall — and the working West Wing including the Oval Office, in a first-person walkthrough or a cutaway dollhouse overview. Hover any object for a fact; click for the full story with a link to Wikipedia. Tour the 18-acre grounds and the Rose Garden, then board Marine One from the South Lawn to fly to Joint Base Andrews and step aboard Air Force One in its 1962 livery. Every dimension is sourced; where the record is classified or withheld, the app says so.
Treasure Hunters
Navigate through maps, solve clues, and hunt for hidden treasures while learning geography and problem-solving skills.
Quiz Karts
A 3D kart racer where the quiz IS the race. Every 10 to 20 seconds a bank of answer gates spans the track, and the only way through at speed is the right answer — the wrong gate is a solid wall, and you restart from a dead stop while seven rivals stream past. Those rivals answer too, so the difficulty you pick is really how often they get it right: on Expert the field answers 92% correctly and out-driving them is not enough. Drift for mini-turbos, collect power-ups you can only open with a correct answer, and read the explanation while you dust yourself off.
Gemfall
A falling-block jewel puzzle where knowledge is the power-up. Every piece arrives with a question — answer it right and the raw block transmutes into the exact gem shape and colours that score highest on your board. Answer wrong and you steer it yourself.

Explore the strange world of quantum mechanics through interactive simulations covering the double-slit experiment, entanglement, tunneling, and Schrödinger's cat.
Air & Mass Lab
Prove that air has mass, then find absolute zero from a balloon in a bucket of water. Six stations of real gas physics — weigh a pumped basketball, squeeze a sealed syringe, burst a balloon in a hot car, race three gases at one temperature — plus a sandbox where you can take any gas in any container to Mars, Everest, orbit or the Mariana Trench. Questions ask you to read your own graphs, predict values and analyse diagrams, not just pick from a list.
Gravity Lab
A sandbox universe running real Newtonian gravity. Drag to launch a planet and watch the orbit you are about to make before you let go, then bend the law itself — turn gravity off, make it fall off as 1/r³, add dark matter, or switch on Einstein and watch an orbit precess. 18 missions, 17 illustrated articles and quizzes where every question asks you to read a graph, a diagram or your own solar system.
Planet Genesis
Build a world from scratch. Pick a star, choose an orbit, pour in an atmosphere, spin it, and switch on a magnetic field — then find out what you actually made. Every choice is real physics: gravity, escape velocity, the greenhouse effect, the habitable zone.

Plant Explorer
A whole world inside one apple tree. Explore realistic blossoms, leaves and roots, travel into living cells, follow photosynthesis atom by atom, and discover how a seed begins its next adventure. Fourteen 3D worlds, interactive experiments, and 112 middle-school questions.
Biosphere
Walk a whole living planet. Twenty-two biomes placed by a real climate model — the rain belt at the equator, the desert belt where that air comes back down, the snow line climbing and falling with the season — and 117 animals that live where they actually live and behave the way they actually behave. Swim off the beach into a coral reef, follow a river to its estuary, cross the ice to find that the penguins are only in the south. Every chart is plotted from the simulation you are standing inside: watch the lynx follow the hares, take the otters out of the kelp forest and watch the urchins answer.
Creature Lab
Build a creature in 3-D, test which foods its body can eat, and release it into a living habitat. Run natural selection, camouflage, inheritance, habitat-change and food-web labs, with wording that grows from K-2 to high school, and keep your evidence in a field notebook.
Evolution
Fly four billion years of ancestry in 3D. Search any living thing — a whale, a mushroom, a T. rex — and watch the rest of the tree fall away to leave its lineage alone. Then press play: 51 real ancestors morph into one another as one continuous animal, from the first cell to today, while the clock counts down and the camera walks the branch. Ten deep-dive stories tell how a whale learned to swim, how a chicken descends from dinosaurs, and how a bat built a wing out of a hand — each with the fossil, the bone or the gene that settled it. A Bones view morphs one forelimb across seven species so you can see the same six bones become an arm, a wing, a flipper and a hoof. A DNA view lets you read a divergence date straight off a protein and check it against the fossils. 636 branches, 100 questions and 8 investigation cases.
Living Aquarium
Explore freshwater and marine habitats from a yellow research submarine, as a diver, or through the movement of an aquatic animal. Observe fish and invertebrates, inspect species facts and sources, record discoveries, and investigate aquarium conditions with educational simulation graphs.
Millimeter World
Shrink to one millimetre and explore a garden. Stand on a leaf in a rainstorm: raindrops the size of exercise balls burst into crown splashes, roll as trembling glass boulders and become lenses that show the garden upside down. Surface tension, terminal speed, ball lenses and the rainbow, seen at the scale where they rule.
Orbit Lab
Fly a real rocket to orbit — and find out why getting there costs 9,500 m/s when the orbit itself only needs 7,800. Pick a launch pad and see what its latitude costs you: Kourou hands you 463 m/s of Earth's spin for free, a polar launch throws all of it away. Fly the gravity turn yourself or tune the autopilot, then read the Δv ledger that splits every metre per second you burned into gravity, drag and steering losses — the one readout that turns "fly a better ascent" into a number that goes down. Then plan: manoeuvre nodes, Hohmann transfers, plane changes, geostationary insertion, re-entry. Switch Earth's equatorial bulge off and watch sun-synchronous orbits stop working, because J2 was the only reason they ever did. Ground tracks drift west because the planet turns underneath you. Orbits decay because the thermosphere is really there. Nothing is animated — the vehicle is integrated by a symplectic solver whose energy drift you can watch on a live plot, and every number the app states is checked against closed-form orbital mechanics by a 52-test harness.
Chemistry Lab
A 3D chemistry bench with twelve real experiments — cabbage indicator, fizz and conservation of mass, elephant toothpaste, precipitates, metal displacement, hot and cold packs, the iodine clock, titration, flame tests, gas laws, a density tower and chromatography. Live pH, temperature and gas readings, a particle view, guided steps for every grade, and an Auto mode that runs each lab for you.
Lava Lamp Lab
Heat a classic lava lamp and watch density flip. Warm wax expands, rises through cooler oil, then sinks at the neck — convection, buoyancy, and immiscible fluids you can see.
Monarch Sanctuary
Stand inside a Mexican oyamel fir grove at sunrise, its boughs sagging under a million sleeping monarch butterflies. Watch the first rays climb the trunks and backlight their stained-glass wings — then press Sunrise Takeoff and see the grove wake into a slow orange blizzard that drifts through the sunbeams and settles again.
Science Gallery
A museum of how we know. Walk through the Chemical Revolution, where real 18th-century engravings and paintings come alive with narration and motion graphics: phlogiston, fixed air, Priestley’s burning lens, Lavoisier’s twelve days of fire and the discovery of oxygen. Run his experiment yourself at the Bench, follow the chain of discoveries on the timeline, watch the room film and take the room check.
Galaxy Simulator
Create swirling galaxies with billions of stars. Watch cosmic collisions, black holes, and stellar evolution unfold.

History
Cities Through the Ages
Seven real street corners, rebuilt once per era, from AD 250 to the year 3000. Pick a city and drag the timeline: the buildings, roofs, shopfronts, signs, traffic, clothes, water level, sky and air all change with the year, and every one of them is period-correct. London is the foot of London Bridge, where a crossing has stood within yards of one line since AD 50. Paris is the right bank at the Pont d’Iéna, where everything permanent on the axis has been demolished and the tower that was licensed for twenty years is still standing — watch it built, in twenty-six months, while you scrub. New York is Greenwich Street at Fulton, where the ground itself is younger than the buildings on it. Tokyo is the palace moat, the one piece of ground in the densest city on earth that nobody may build on. Rome is a road that has not moved while the ground rose twelve metres over it. Mexico City is a centre of power that never shifted, and Los Angeles is the plaza of 1781 under the freeway. Walk each street at eye level or orbit the whole block, and click the markers to read what you are looking at.
