Mysterious Journey
This ThinkQuest site concentrates on three of the world's major biomes: rain forest, grassland and desert. The site is divided into three parts according to the three biomes. In each part, the climate, location, animals, plants and human activities of the biome are presented. There is a treasure hunt game for encouraging students to take the initiative to learn about the three biomes. There is a search engine and links for further information. In addition, a discussion forum with controversial t

A Natural Fusion: Math and Science Across the Curriculum : Northwest Teacher, volume 4 number 1
Articles in this issue of Northwest Teacher focus on integrating math and science across the curriculum. Teachers create learning experiences for students, of all grade levels, that transcend the power of any one of them taught in isolation. With todays national spotlight on improving students reading and math skills, the potential for cross-disciplinary teaching of these subjects may be readily apparent. But science, too often nudged to the hinterlands of the curriculum when state standards and

Plate Boundaries
This site provides information on plate boundaries, which are found at the edge of the lithospheric plates and are of three types: convergent, divergent and conservative. Wide zones of deformation are usually characteristic of plate boundaries because of the interaction between two plates. The three boundaries are characterized by their distinct motions which are described in the text and depicted with block diagram illustrations, all of which are animated. There are also two maps that show the

Dancing Penny
This physical science activity was designed to engage students in thinking about the scientific principles involved in a teacher demonstration. In the demonstration, a coin resting in the opening of a bottle moves up and down when energy is transferred from a teacher's warm hands to the air inside the bottle. This conduction of heat increases the air temperature and pressure inside the bottle. The activity includes instructions for teachers, a materials list, science process skills used in the a

Observe common objects made of minerals
This interactive Earth science resource lets students first see six images of minerals and then, by placing their cursor over each image, an image of an everyday object made from that mineral. Quartz, gypsum, and fluorite are among the minerals shown, with the corresponding familiar objects being glass, drywall (Sheetrock), and toothpaste. Copyright 2005 Eisenhower National Clearinghouse

The National Math Trail
The National Math Trail makes available problems created by K-12 students as they explore their communities and ask math questions that relate to their own environments. Teachers submit the problems to the site, along with photos, drawings, sound recordings, and videos. Problems can be accessed through an interactive map of the United States.

Interactive atmosphere lab
The ozone layer makes up an important part of our atmosphere. This informational activity, part of an interactive laboratory series for grades 8-12, explores changes in ozone concentration with altitude. Students view a diagram that shows the layers of the atmosphere with a temperature scale running from the surface of the Earth to the outermost reaches of the atmosphere. After reading introductory material, students are presented with nine questions about the layers of the atmosphere and intera

Our Solar System
This site contains information about the nine planets, the sun, and the moon. Included is each planet's size compared to the sun. Students can click on a picture to discover the following information: the diameter, mass, temperature, number of rings, what it's made of, can life exist there, and other interesting facts. Included for each planet are the number of moons, length of a day and year, and the average distance from the sun. Students can enter their weight to find out how much they would

Fossil Fuels
How much does the United States depend on fossil fuels? This web page, part of a site on the future of energy, introduces students to fossil fuels as an energy source. Here students read about the uses, benefits, and limitations of fossil fuels. There is also information on how these fuels are distributed geographically and how they affect the U.S. economy through supply and demand. Thought-provoking questions afford students opportunities to reflect on what they've read. Articles about clean co

Energy Transfer
How can a Ping-Pong ball be made to bounce higher without throwing it downward harder? This material is part of a series of hands-on science activities designed to arouse student interest. Here students investigate energy transference and momentum by simultaneously dropping a Ping-Pong ball sitting directly above a golf ball and measuring the bounce height. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of appl

Ecological Footprint: Only One Planet
This two-minute sound segment discusses the concept of your ecological footprint. This is the amount of nature it takes to support your lifestyle. The speaker explains that if we divide up the total ecologically productive space on the planet by the number of people, what we get is five acres per person. In the United States, on average, we use about twenty-five to thirty acres per person to provide all of our services. This site is from an archive of a daily radio program called Pulse of the Pl

In this section we are going to review the different needs that drive the creation of corporate governance frameworks. The contingent model of regulation applies to financial reporting: the idea that equilibrium in regulation exists, but is broken by some intrusive event, often a financial scandal. This leads to a search for a revision of the rules, and a new equilibrium is worked out. This is very much a pattern that drives change in corporate governance.
