Water Science for Schools
We offer information on many aspects of water, along with pictures, data, maps, and an interactive center where you can give opinions and test your water knowledge. Looking at water, you might think that it's the most simple thing around. Pure water is colorless, odorless, and tasteless. But it's not at all simple and plain and it is vital for all life on Earth. Where there is water there is life, and where water is scarce, life has to struggle or just "throw in the towel." So what is it about w
The Water Science Picture Gallery: A Flowing Well
This image is part of the U.S. Geological Survey's Water Science for Schools website. Other imagery includes photographs of water being measured and sampled, being used in various ways, and illustrations of how human activity influences the water system. Written descriptions of activities being shown are provided. Links to other parts of the Water Science for Schools website are also present.
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
This document provides general guidance on how to install and use piezometers and water-table wells to investigate soil water regimes under conditions commonly encountered in Soil Survey and hydropedology studies.
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,
How to Make a Volcano
Making a volcano involves mixing active yeast, warm water, hydrogen peroxide, a bit of red food coloring and dish soap together into a small container to create a chemical reaction. Create a volcano, under parental supervision, with a demonstration from a science teacher in this video. Run time 03:37.
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
West Coast Field Guide of the National Marine Sanctuaries
Our five West Coast national marine sanctuaries encompass nearly 12,000 square miles of ocean, which includes hundreds of miles of dramatic coastline. Teeming with life and filled with history, they offer countless opportunities for exploration, recreation and contemplation. This guide will introduce you to the natural and cultural wonders of your national marine sanctuaries. Whether you're traveling on foot or bicycle, by car or by boat, above water or diving below, it can lead you to new disco
Edward Shorter on the history of sex - 2005
Edward Shorter delivers a lecture discussing the history of sex and his book Written in the Flesh at Hart House at the University of Toronto - September, 2005.
History: Ask a Question
lets students correspond with government historians via email. Historians' names and addresses are listed by expertise with an emphasis towards those researching the national parks, the National Park Service, and American history.
Maps of Indian Territory, the Dawes Act, and Will Rogers' Enrollment Case File
This lesson encourages students to study a variety of documents to understand the impact of a particular piece of legislation and relates to the powers granted to Congress in Article I, Section 8 , of the Constitution, related to making laws. It correlates to the National History Standards and the National Standards for Civics and Social Sciences. It also has cross-curricular connections with with history, government, global studies, and music.
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
