Where Deserts Form
Most of Earth's deserts can be found in dry areas created by global circulation patterns. The deserts of our world are not restricted by latitude, longitude, or elevation. This site, produced by the U.S. Geological Survey, uses text and pictures to describe how atmospheric circulation patterns influence the locations of deserts on Earth and possibly on other terrestrial planets as well.
Installing Monitoring Wells in Soils

Doing the right thing: corporate social responsibility in a global marketplace
Globalisation, mass consumer awareness and public accountability are all factors in persuading companies to adopt ethical policies. As companies become more accountable not only for their own actions but for those within their supply chain, they have to adapt to ensure success within the context of the global society they operate in. Professor Jeremy Moon (Professor of Corporate Social Responsibility at the University of Nottingham Business School and Director of the International Centre for Co
Superspace: One Thousand and One Lessons in Supersymmetry
We introduce superfields in chapter 2 for the simpler world of three spacetime dimensions, where superfields are very similar to ordinary fields. We skip the discussion of nonsuperspace topics (background fields, gravity, etc.) which are covered in following chapters, and concentrate on a pedagogical treatment of superspace. We return to four dimensions in chapter 3, where we describe how supersymmetry is represented on superfields, and discuss all general properties of free superfields (and the
WISE - The Web-Based Inquiry Science Environment
The Web-based Inquiry Science Environment (WISE) is a free on-line science learning environment for students in grades 4-12. In WISE, students work on exciting inquiry projects on topics such as genetically modified foods, earthquake prediction, and the deformed frogs mystery. Students learn about and respond to contemporary scientific controversies through designing, debating, and critiquing solutions, all via the internet. Curriculum projects are complete and ready to use in the classroom. The
"Water Alert!" is an interactive educational resource on water, environment and sanitation where young people are engaged in an adventure of strategy and survival. The goal is to ensure that the people in this drought-challenged village, who are facing the threat of a flood, have water that is safe to drink and a clean and healthy school environment. Includes a facilitation guide with instructions for use of the game as a teaching tool and suggestions for classroom activities relating to water,

The Fact of Global Warming
Slowly, the globe confronts global warming. Quickly, the globe warms. But can we trust computerized climate models? What's happening to the oceans and the ice? Could warming damage your lungs?
Global Climate Change: Environmental Studies 245
This website is the homepage of the St. Olaf interdisciplinary course, Global Climate Change. The course focuses on how and why Earth's climate has changed throughout its history and how it is likely to change in the near future. The course draws from geology, chemistry, meteorology, oceanography, and policy studies. Much of the science involved in this topic is cutting-edge, so quite a bit of the reading will be from scientific journals. Users can follow links to a PDF syllabus and assignments

Greenland's Receding Ice
After Antarctica, Greenland's ice cap contains the second largest mass of frozen fresh water in the world. Based on new research using NASA's airborne laser altimeter, scientists have identified pronounced thinning of Greenland's ice cap. This new research indicates enough ice loss to cause a measurable ...
Spyhopping is when orcas vertically propel themselves halfway out of the water and stay there for a moment, akin to a human treading water. They do this to sneak a peek at their surroundings above the surface - most commonly for food, but also just to see how close they are to shore. No narration. Run time 0:48.
What is the Spyhop?
What Is The Spyhop? Watch this cool video from explore.org and see the Orca Whales jumping and “hopping” out of the water. This fun move allow them to shoot themselves halfway out of the ocean and then stay still, treading water. This allows them to see if any tasty meals are around, and also to learn their location and where they are in relation to the shore line. Watch and learn all about the Spyhop! No narration. Video is set to music with information written at the bottom of the screen

"Wheelchair Design in Developing Countries, Spring 2009"
"According to the United States Agency for International Development, 20 million people in developing countries require wheelchairs, and the United Nations Development Programme estimates below 1% of their need is being met in Africa by local production. Wheelchair Design in Developing Countries (WDDC) gives students the chance to better the lives of others by improving wheelchairs and tricycles made in the developing world. Lectures will focus on understanding local factors, such as operating e
"History and Anthropology of Medicine and Biology, Spring 2009"
" This course explores recent historical and anthropological approaches to the study of life, in both medicine and biology. After grounding our conversation in accounts of natural history and medicine that predate the rise of biology as a discipline, we explore modes of theorizing historical and contemporary bioscience. Drawing on the work of historian William Coleman, we examine the forms, functions, and transformations of biological and medical objects of study. Along the way we treat the hist
