Energy Education Showcase: How MIT is Preparing Students for New Challenges
In 2009, MIT launched an unusual academic venture, an interdisciplinary minor devoted to energy studies. A panel of MIT professors discuss their aspirations and work to date shepherding this new program into existence.
Vladimir Bulovic gives full credit to students for jumpstarting the energy minor. They wanted sch
3D gaming without the glasses
Nintendo's launch of its handheld 3DS gaming system, the first device to offer 3D gaming without special glasses, was met with a big crowd, but competition from smartphones could threaten future growth.
Exercises on Section 2
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
Reasoning and Proof
From the early grades on, students develop their reasoning skills by making and testing mathematical conjectures, drawing logical conclusions, and justifying their thinking in developmentally appropriate ways. As they advance through the grades, students' arguments become more sophisticated and they are able to construct formal proofs. By doing so, students learn what mathematical reasoning entails.

USDA Forest Service-St. Paul Field Office: Silvics of North America
The Internet continues to evolve as a global library, allowing free and easy public access to an increasing number of valuable documents. One such treasure, found in the archives of the USDA Forest Service St. Paul Field Office website, is _ Silvics of North America_, a substantial publication describing "the silvical characteristics of about 200 conifers and hardwood trees in the coterminous United States, Alaska, Hawaii, and Puerto Rico. Individual articles were researched and written by knowl
Bermuda Atlantic Time-series Study
The Bermuda Atlantic Time-series study (BATS) was initiated to collect oceanographic data over significantly long time periods. At this website, researchers will find BATS and hydrostation data dealing with hydrographic, chemical, and biological parameters throughout the water column for sites in the Sargasso Sea. Visitors can learn about the first BATS station, Hydrostation S, which was initiated in 1954 by Dr. Henry M. Stommel and has been visited biweekly almost continuously ever since. The w
As part of the CATlab project at the University of New Hampshire, Project54 is an integrated system of electronic devices that allows police officers "to interact with equipment such as lights and siren, radar, etc. using speech input and feedback." This website offers a detailed description of the system and its purpose, an image gallery, and several publications and project proposals. Visitors to the site who complete a brief registration can download an interactive demonstration of the Projec
The Interactive Plasma Physics Education Experience
As part of Princeton University's Plasma Physics Laboratory, the Interactive Plasma Physics Education Experience Web site contains interactive plasma physics topics, ranging from electricity and magnetism to energy and fusion. Although some of the activities have difficulty running on old browsers and Macintosh computers, the interactive lessons give students a fun and engaging way to explore physics topics.
Bridge Building: Art and Science
This site is one of the most substantial, comprehensive sources on the Internet dedicated to bridge design and history. It has an incredible list of sections from which to choose, and each describes a particular bridge type or characteristic. Several pictures are included from all over the world that give examples of arch, truss, suspension, and many other bridge designs. There are also explanations of forces that act upon bridges, as well as what issues are considered when choosing the kind of
Mars Exploration Rover Mission
Scheduled for launch in 2003, two NASA rovers will set out to explore Mars and determine whether water ever existed on the planet. This is the home page of the Mars rovers, and it has a great deal of information about the specifications and technology of the missions. Detailed descriptions of the scientific instruments equipped on each rover are provided. Color diagrams show the main components of the rovers. A special section is dedicated to the camera systems, which are used for hazard avoidan
The Tree of Life
The Tree of Life is a collection of about 2000 World Wide Web pages containing information about the diversity of life. These pages are authored by biologists from around the world... Each page contains information about one group of organisms. The pages are linked one to another in the form of the evolutionary tree of organisms, with the pages branching off from a group's page being about subgroups. This vast site contains a large collection of biological images, most of which can be reproduced
Toshiba/NSTA ExploraVision Awards
ExploraVision is a competition sponsored by Toshiba, Inc. and the National Science Teachers' Association (NSTA). The competition, which is open to all students in grades K-12 attending a school in the U.S., Canada, U.S. territory or a Department of Defense school, provides students a chance to "develop skills that will prepare them well for the 21st century workplace." Through ExploraVision, students work in teams to select a technology, research how it works and why it was invented, and then gi
Welcome to the Web

Using technology to support Limited-English-Proficient (LEP) students' learning experiences
This article examines the challenges and rewards related to using technology as a tool to increase learning for limited English-proficient (LEP) students. The article is based on the belief that students' content, linguistic, and technology skills should be developed in tandem. Strategies and standards for technology use are featured along with suggestions for enhancing LEP students comfort level in content classes. Access and equity and the redefinition of teacher roles are also discussed. Impr
Observe an animation of a comet's passage through the solar system
With these animations, Earth science students can follow the 76-year orbit of Halley's Comet. The introduction describes the highly elliptical orbit of comets and states that comet Halley will return to the solar system in the year 2061. Students are instructed to choose between a wide-angle view of the comet's entire orbit and a view of the comet's path through the inner solar system. The wide-angle view shows how the comet's velocity increases as it approaches the sun and decreases as it trave
