Planets orbiting the Sun at different speeds and distances.
Atom Lab
Build any of the first 20 elements proton by proton, then travel through 3,500 years of atomic discovery on the element timeline.
Planet Earth
A realistic, rotating Earth with oceans, continents, clouds, atmosphere and the orbiting Moon.
Reaction Lab
A virtual chemistry bench: mix acid and base with an indicator, and set off a gas reaction — measure temperature, watch the colour change and test your predictions.
Human Cell
Explore a detailed animal cell — membrane, nucleus, mitochondria, ribosomes and cytoplasm.
Motion Lab
Launch projectiles at any angle and speed, then drop objects on Earth, the Moon and Jupiter to feel how gravity changes motion.
Electric Circuit
A working series circuit — battery, switch, wires and a glowing bulb you can inspect part by part.
