The self-healing antitank minefield is an innovative system developed by the Defense Advanced Research Projects Agency (DARPA). It employs intelligent, mobile mines that can rearrange themselves to repair any breaches in the field. This forces the enemy to destroy a much greater percentage of the total mines, rather than simply clearing a narrow path. The project's Web site has considerable material on the mines' operation, including a very illustrative multimedia demonstration. There are also b

StarTiger is a project of the European Space Agency that is testing a new framework for research and development, with the goal of dramatically reducing the time needed to achieve a breakthrough. The basic method is to assemble a group of doctorate level researchers and engineers, put them in an environment that is free of distractions, and give them access to state-of-the-art equipment and technology. The first success of StarTiger was realized in October 2002, when, after only four months of w

Gflow 2000, which was developed by Haitjema Software, is described as a highly efficient stepwise groundwater flow modeling system. It is based on the analytic element method and models steady state flow in a single heterogeneous aquifer using the Dupuit-Forchheimer assumption, and is particularly suitable for modeling regional horizontal flow. The free educational version of the software is available for download from the site, as well as descriptions of the analytic method, stepwise modeling,
Reproductive & Cardiovascular Disease Research Group
The Reproductive & Cardiovascular Disease Research Group is "based in the Department of Biochemistry and Immunology at St. George's, University of London." The Group's "research interests include a number of areas concerned with reproductive and cardiovascular diseases such as trophoblast biology, nitric oxide and apoptosis, with particular emphasis on the role of these subjects in diseases of pregnancy such as pre-eclampsia." This website contains descriptions of protocols commonly utilized by
University of Newcastle upon Tyne: Department of Statistics
The Department of Statistics at the University of Newcastle upon Tyne has an impressive Web site with a lot of good research information. The Research section of the site is divided into five different group areas, consisting of applied statistics, applied probability, medical statistics, Bayesian statistics, and bioinformatics. Each of these has a statement of the work performed and a list of recent publications. The Postgraduate Study section discusses a number of research projects currently u
Performance Assessment Links In Science (PALS)
This searchable resource contains a list of performance assessment tasks, aligned with and linked to National Science Education Standards. The resources are collected from a variety of reputable sources, such as the Third Annual Math and Science Study (TIMMS) and the NY State Education Department. The tasks include student directions and response forms, administration procedures, scoring rubrics, examples of student work, and technical quality data calculated from field testing.

Observe forest fires as seen from space
This Earth science resource shows students how atmospheric scientists use infrared imaging to detect and locate forest fires. The introduction explains how visible-light images recorded by satellites are unable to distinguish smoke from clouds. In contrast, infrared imaging, which detects heat, can detect hot spots that indicate the location of forest fires. The resource provides two different sets of satellite pictures. Students are instructed to toggle between the visible-light and infrared im
Quick take on area and volume
This one-page document highlights online resources with virtual manipulatives that can help make area and volume real for students. Be sure to check out the sites these resources are from; the sites contain many other interesting and useful mathematics learning resources.
Examine the sun at different wavelengths
This Earth science resource enables students to observe and compare the sun's appearance under different types of electromagnetic radiation. Students are instructed to move the cursor across the spectrum to see images of the sun under radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays. Each image includes a label that indicates the portion of the electromagnetic spectrum, the wavelength in angstroms and meters, and the layer of the sun in view. Copyright 2005 Eisenhow
Atlas of the Cyrosphere
This site from the National Snow and Ice Data Center (NSIDC) allows visitors to explore and dynamically map the Earth's frozen regions. Viewed from a polar perspective, the available data sources include snow cover, sea ice extent and concentration, glaciers, ice sheets, permafrost, and other critical components of the Earth's cryosphere. Users can zoom in to a specific region on the Earth as well as overlay country borders, major cities, and other geographic information. This site provides a ge
