Interactive exploration Earth, Weather & Climate Ocean tides, high and low water, spring and neap tides Why does the sea rise and fall each day? Keep one clock at three real waterfronts. Reveal which water level rises next, build a tide from repeating rhythms, and discover why the Moon does not give every coast the same pattern.
Coastal records & tidal rhythm lab Explore at your own pace
Interactive exploration Earth, Weather & Climate Volcanoes, magma, lava and why eruptions differ Why can lava flow, fountain—or break into fragments? Watch real lava feed a channel. Take apart a gas-volume calculation, compare Mount St. Helens through time, inspect volcanic rock under a microscope and explore an actual surveyed crater.

Interactive exploration Earth, Weather & Climate Thunderstorms, cloud growth, moisture, lifting and updrafts What helps a cloud grow into a thunderstorm? Step through real satellite observations, release an air parcel into a measured atmosphere, and discover why moisture, lifting and the surrounding air all matter.

Interactive exploration Earth, Weather & Climate Air quality, PM2.5, particle filters, ventilation and AQI What is hiding in the air you breathe? Open a room, plan when to exchange its air, and lift the cover off a particle filter. Follow the mass, inspect real observations, and discover what an AQI number can—and cannot—tell you.

Interactive exploration Earth, Weather & Climate Earthquakes and seismic waves How can three stations help locate an earthquake? Watch waves emerge from a buried source, pick synthetic arrivals and reveal the location one clue at a time. Test the clocks, depth and velocity assumptions—and compare the model with real recorded evidence.

Interactive exploration Earth, Weather & Climate The greenhouse effect How can a planet warm without receiving more sunlight? Freeze two model temperatures, change infrared transfer and release time. Follow every energy route, move the accounting boundary and compare the model with real atmospheric evidence.

Interactive exploration Earth, Weather & Climate The water cycle Where can a drop of rain go next? Follow water above and below the surface. Pave part of the land, change evaporation, and watch the water budget rearrange.

Interactive exploration Earth, Weather & Climate Plate tectonics and moving continents How can moving rock leave a clock on the ocean floor? Pull a ridge apart over millions of years. Read the age and magnetic pattern left behind, then compare spreading, sliding and subduction.
