Discover how the world works through interactive experiments, field guides, and hands-on explorations of the natural world.
Explore how molecules behave in solids, liquids, and gases with an interactive particle simulator. Watch phase changes happen in real time!
Start exploring → 🐠 🪸Learn to identify common reef fish found in the Florida Keys. Study their features, explore the catalog, then test yourself with an interactive photo quiz!
Explore reef fish → ⚡ 💡Snap together batteries, bulbs, switches, and resistors to build working circuits. Watch animated electrons flow when your circuit is complete!
Build a circuit → 🪐 🚀Journey through our cosmic neighborhood — explore the Sun, eight planets, asteroids, and comets. Click planets for facts, then test your knowledge with an ordering quiz!
Explore the solar system → 🌊 🌈Play with a live Wave Lab to see how frequency and amplitude change pitch, volume, color, and brightness — then test your knowledge with a quiz!
Explore waves → 🪞 🌀Explore what happens when waves meet matter — transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered — with a hands-on Wave Behavior Lab!
Explore behaviors → 🛤️ 💥Launch carts at each other on a virtual Glide Track — adjust mass, speed, and direction, then see how momentum and kinetic energy play out in elastic and inelastic collisions!
Explore energy & momentum →
