Search the USDA National Nutrient Database for Standard Reference
The USDA Agricultural Research Service Nutrient Data Laboratory presents the National Nutrient Database, which has an easy-to-search interface that quickly retrieves nutritional data for every food item that contains a specific keyword. For instance, searching for "soybean" calls up a long list of food items for which soybean is an ingredient: various margarines, salad dressings, and oils; raw soybeans; steamed soybeans; roasted soybeans; and so on. The complete nutrition report for each item ca
Discovery Channel: Kitchen Chemistry

Students can learn about common chemical compounds in the kitchen including sugar, starches, fats, and proteins. The website offers suggestions on how an understanding of chem
Daily Lesson Plan: Brain Brands
Why do those holiday cookies and candies -- placed conveniently at child height at the cash register -- get you drooling and entice you to fill your cart with unintended purchases? It might be neuromarketing at work. In this thought-provoking activity, created by Georgia Scurletis and Briget Anderson and offered through the _New York Times_ LearningNetwork, students (grades 6 - 12) are challenged to think about how branding and marketing may influence their taste more than their taste buds thems
The University of Southampton: Geology of the Wessex Coast, Southern England
Ian West, a retired professor at the University of Southampton, developed this expansive database of geological field guides to the Wessex Coast of southern England. The website divides the information on the fossils, offshore geology, formations, and much more into smaller units within the Coast. The field guides can be viewed by stratigraphical units and localities. Students and educators can learn about the Jurassic, Cretaceous, and Palaeogene strata of the area through countless photographs.
Spike's Science Projects
Over 400 science projects, drafted by a professor of Science, are published on this educational Web site. Projects from various scientific fields include animals, atoms, ecology, meteorology, microorganisms, and more. Most of the projects are fun, informative, and can be completed easily with household items.
Dino Discovery: A Paleo Explorer Kids Adventure
This Macromedia Flash Player-enhanced website, developed by the Raymond M. Alf Museum of Paleontology in Claremont, Calif., allows students to explore dinosaur fossils in the Cretaceous rocks of the Kaiparowits Formation in Utah. Through the tutorial users can discover the different types of Cretaceous and Jurassic rocks. Students can learn about the techniques used in the field to look for fossils, excavate findings, and protect and preserve the collected specimen. The website follows with shor
Mechanical Engineering: Power 2002
The American Society of Mechanical Engineers presents this special edition of its Mechanical Engineering Magazine Online. Released in June 2002, the focus of this publication is electric power. Research efforts and new technologies for a variety of applications are outlined in five feature articles. One article covers turbo pumps in the space shuttle, considering how to minimize cavitation problems to make the pumps more efficient. Another looks at research into flow oscillations that plague gas
Consensus CoDing Sequence Database
The Consensus CoDing Sequence (CCDS) Database "project is a collaborative effort to identify a core set of human protein-coding regions that are consistently annotated and of high quality. The long-term goal is to support convergence toward a standard set of gene annotations on the human genome." CCDS project collaborators include the National Center for Biotechnology (NCBI), European Bioinformatics Institute (EBI), Wellcome Trust Sanger Institute (WTSI), and University of California, Santa Cruz
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,
Bush Cites Need to Develop Affordable Hydrogen-Powered Fuel Cells
In his State of the Union Address on January 28, 2003, President Bush made a case for further fuel cell development. Current efforts in this area have not determined how to efficiently produce or extract hydrogen for the cells. In hopes of solving this problem, Bush proposed a $1.2 billion FreedomFUEL initiative. The first site discusses the initiative and its potential to create a nearly pollution-free method of electricity generation.
QuickMath: Automatic Math Solutions
QuickMath is one of the most useful sites for common but tedious mathematical calculations. It is a free "online calculator that solves equations and does all sorts of algebra and calculus problems." Separated into many different functional sections, this handy tool can simplify expressions, evaluate symbolic integrals, plot equations, and much more. When inputting a problem into QuickMath for it to solve, users have an option to use basic or advanced controls depending on the problem's intricac
In this lesson, students model a bungee jump for a Barbie doll. They collect data in a table (number of rubber bands and jump distance), then create a scatterplot of the data, find its line of best fit, and write an equation of that line. Students go on to analyze the equation, noting its slope in relation to the data collected, and the meaning of the y-intercept. Since the distance to which the doll will fall is directly proportional to the number of rubber bands, the lesson provides a scenario

Ice Cube of Exotic Microbes
This article describes a permafrost subglacial lake discovered beneath Antarctica. The lake offers scientists a chance to test their sterile drilling techniques before exploring elsewhere in search of exotic microbes. Techniques that avoid contaminating a drill site with microbes, suggests the author, would prove useful for future drilling into Mars polar caps in search of life.
