The site includes a link for teachers providing an introduction, overview of concepts explored in the trip, lesson plans, and additional web links. The electronic field trip may be viewed in a low bandwidth version without downloading. For a high bandwith version of the field trip, Macromedia Flash Player is required and can be downloaded on site. Further informat
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
Sound Waves Underwater : True or False
This interactive quiz from the NOVA Web site features an array of interesting facts about the nature of sound underwater.
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
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
National Oceanic and Atmospheric Administration : Research Homepage
National Oceanic and Atmospheric Administration (NOAA) Research, conducted primarily through the NOAA Office of Oceanic and Atmospheric Research, drives the NOAA environmental products and services that protect life and property and promote sustainable economic growth. Research, conducted by in-house laboratories and by extramural programs, focuses on enhancing understanding of the environmental phenomena such as tornadoes, hurricanes, climate variability, solar flares, changes in the ozone, El
2.1 Introduction 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.

Students will be asked to be part of a hypothetical scenario that challenges them to inform customers at a local restaurant of how their use and disposal of plastics relates/contributes to the Great Pacific Garbage Patch (GPGP). What they ultimately must do is to research information on the GPGP and place that information into a short, eye-catching newsletter that they can “hand out” to restaurant customers. This activity focuses on teaching students to gather their own additional informatio
Students design and build a model city powered by the sun! They learn about the benefits of solar power, and how architectural and building engineers integrate photovoltaic panels into the design of buildings.
Student groups act as assembly lines producing paper airplanes, and learn to apply engineering principles to manufacturing. Their objective is to create as many quality paper airplanes as possible at low cost. The teams see their production numbers increase by applying pull manufacturing and other techniques to increase efficiency, and optimize the production process. Ultimately, hypothetical profit is calculated for each group, to emphasize important aspects of the manufacturing process.
Students learn about the engineering design process and how it is used to engineer products for everyday use. Students individually brainstorm solutions for sorting coins and draw at least two design ideas. They work in small groups to combine ideas and build a coin sorter using common construction materials such as cardboard, tape, straws and fabric. Students test their coin sorters, make revisions and suggest ways to improve their designs. By designing, building, testing and improving coin sor
Bernoulli’s principle relates the pressure of a fluid to its elevation and its speed. Bernoulli’s equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity. Students learn about the relationships between the components of the Bernoulli equation through real-life engineering examples and practice problems.
While learning about volcanoes, magma and lava flows, students learn about the properties of liquid movement, coming to understand viscosity and other factors that increase and decrease liquid flow. They also learn about lava composition and its risk to human settlements.
Students conduct Internet research to investigate the purpose and current functioning status of some of the largest dams throughout the world. They investigate the success or failure of eight dams and complete a worksheet. While researching the dams, they also gain an understanding of the scale of these structures by recording and comparing their reservoir capacities. Students come to understand that dams, like all engineered structures, have a finite lifespan and require ongoing maintenance and
Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river’s ecosystem can be determined by its river insect population.
