What's the Angle?

Why is there such a dramatic temperature change between the equator and the South Pole? Explore all the angles of sunlight with a few thermometers and a heat lamp.

Seasonal Cycle

If the Earth turns all the way around every 24 hours, then why are some days longer than others? And why do we have winter and summer? See the answers for yourself—in a matter of seconds.

Make Your Own Weather Station

Surrounding Earth is a layer of air, the atmosphere, where conditions are always changing. Try your hand at predicting weather patterns by making a wind vane, a rain gauge, and a barometer.

Meteorology in the Poles

It takes only about a month for any change in Antarctica's weather to be felt in North America—pretty remarkable when you consider that Antarctica is 12,874 kilometers (8,000 miles) away.

Studying Ice Flows for Clues to Climate Change

What's better than watching ice melt? Building a computer model to simulate the melting! Ice flow plays an important role in everything from deep ocean circulation patterns to global warming.

Classroom Activity

Crazy Cold Air

Why does cold air rush out of a freezer when you open the door? How does it then move through a room? Experiment to learn the answers—and gain insight into the blustery winds of Antarctica.

Derecho

On July 4, 1999, a rare and terrifying storm swept through the Boundary Waters Canoe Area Wilderness in northern Minnesota. What began like a standard-issue thunderstorm soon turned strange and fierce, generating green clouds and strong winds reminiscent of a tornado. In fact, the storm was a cousin of the tornado: a derecho (pronounced "de-RAY-cho"), a type of storm so infrequent and fast-moving that only in recent years have meteorologists begun to understand how to recognize and forecast it

Studying Tree Rings to Learn About Global Climate

By taking biopsy-like samples from centuries-old Siberian pines, scientists have reconstructed a 300-year record of temperature changes for the Arctic and the Northern Hemisphere.

NAO: Driving Climate Across the Atlantic

For centuries, a massive atmospheric system has regularly altered weather patterns, fishery production and animal migrations across the North Atlantic Ocean. At last, Earth scientists and climate modelers are beginning to understand how--and when - the North Atlantic Oscillation happens.

Building a Cloud Chamber (Cosmic Ray Detector)

Wouldn't it be cool if you could create a rain cloud? Or call cosmic rays into view? Well, you can do both! All you need is an aquarium, a slide projector, dry ice, and a few other easy-to-get supplies.
