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.


Classroom Activity

How Does Where You Live Shape How You Live?

With access to products and information from around the world, our range of choices is seemingly endless. But how would life be different if you lived in a different time and an isolated place?


Classroom Activity

To Rot or Not to Rot

From hot deserts to frozen tundra to underwater caves, archaeological sites can be as diverse as our planet’s environments. See why some evidence from past cultures survives over time and some doesn’t.



Do Your Own Dig

With a few simple tools from around the house and garden, you can execute a sound archaeological dig. Level by stratigraphic level, learn how to find and analyze objects like a pro.

Reading the Rocks: The Search for Oil in ANWR

In 1980 an act of Congress set aside nearly 20 million acres of Alaska's North Slope tundra to create the Arctic National Wildlife Refuge (ANWR). Less than 100 miles from the refuge is Prudhoe Bay, North America's largest oil field. Spread across what was once part of the largest intact wilderness area in the United States, Prudhoe Bay and its neighboring oil fields account for approximately 25 percent of U.S. domestic oil production.


Science Bulletin


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

Space Weather: Storms from the Sun

Once upon a time, back in the twentieth century, the weather was straightforward: it rained or snowed, skies were sunny or cloudy. However, in the twenty-first century—the era of globalization and digitalization—a whole new kind weather is critical to consider: space weather.
Space weather is direct product of our local star, the Sun. The Sun continuously sheds its skin, blowing a fierce wind of charged particles in all directions, including Earth's. From time to time, storms on the Sun's surface—solar flares, coronal mass ejections—toss off added masses of energy and ions. When that turbulence slams into Earth, it produces space weather. The consequences can be spectacular, from colorful auroras to satellite, power and communications failures.
Space weather isn't new: the Sun has buffeted Earth with solar particles since the planet first formed. What has changed is society. This feature reveals how our increasing use of satellite technology has made us vulnerable to solar storms, and how solar scientists—"space weathermen"—are learning how to predict and forecast the Sun's activity.
