This Web site is useful for evaluating industrial chemicals or for environmental assessment research.
Cryptology ePrint Archive
The International Association for Cryptologic Research (IACR) maintains this archive of nearly 400 research papers on various topics in cryptology. Contents date back to 1996, and new material is posted most weeks. Papers generally describe original theories about a certain topic, analyses of cryptologic methods, or proofs of specific equations. Anyone can submit their research for possible inclusion in the archive. There is not an extensive refereeing process, which allows authors to more quick
Brainpop describes itself as the leading producer of educational animated movies. Their Web site has a science page that currently contains sixty-five animated movies, with a large portion of them being physical science related. Each subject contains a 3-4 minute Movie, an Interactive Quiz, an Experiment, a Comic Strip, a How-to hands-on application, a Timeline, and a printable Activity Page. Visitors can play three movies per day for free (all of which begin by a somewhat annoying ad for subscr
"The Digital Bridges Web site consists of a collection of thirty representative 19th century American bridge engineering monographs, manuals, and documents from the Lehigh University Libraries' Special Collections." The archive provides an interesting retrospective into the beginnings of major bridge projects; the material is complete with high-resolution photographs and text scanned from original books. In addition to historical literature, Digital Bridges also features brief accounts of notabl
Worm Watch is part of NatureWatch (first reported on in the May 31, 2002, NSDL Scout Report for Life Sciences), which is series of programs--administered collaboratively by the Canadian Nature Federation, the University of Guelph, and the Ecological Monitoring and Assessment Network--that "encourage schools, community groups, individuals, naturalists, backyard enthusiasts, Scouts and Guides to engage in the monitoring of soil, air, water and other aspects of environmental quality." For students
Honey Bee Brain EST Project
Honey bee RNA data from a recent study at the W.M. Keck Center for Comparative and Functional Genomics at the University of Illinois at Urbana-Champaign has been integrated with gene research on other organisms to create this database. The project is intended to provide updated information on honey bee genes, supplemented with information from other organisms to "suggest cellular roles, biological functions, and evolutionary relationships." Users can search for information by BLAST sequence, key
From Flying Publisher, _HIV Medicine 2005_ is a free, online "medical textbook that provides a comprehensive and up-to-date overview of the treatment of HIV Infection." This edition is an update of the 2003 version of the textbook (reported on in the June 13, 2003 NSDL Scout Report for Life Sciences). Chapter titles in the textbook include HIV Testing, HIV and Pulmonary Diseases, Mitochondrial Toxicity, HIV and HBV Coinfections, and Traveling with HIV, to name a few. The textbook is available in
Earth Today: A Digital View of our Dynamic Planet
Earth Today: A Digital View of our Dynamic Planet is offered by the Smithsonian Institution's National Air and Space Museum and is described as a "state of the art digital theater that's updated several times daily to show near real-time satellite views of the Earth's atmosphere, oceans, and landmasses." The Our Dynamic Earth section contains several topics, such as The Atmosphere, in which users can read about the subject and see impressive satellite images and animations of Earth from space. T
Silent Spring Institute
Named after ecologist Rachel Carson's landmark book, _Silent Spring_, the Silent Spring Institute (SSI) is a "scientific research organization dedicated to identifying the links between the environment and women's health, especially breast cancer." The SSI website contains descriptions of several research projects including the Cape Cod Breast Cancer and Environment Study, Geographic Information System Exposure Assessment, Groundwater and Drinking Water Initiatives, and Household Exposure Study.
The Activities page of the EarthNet Web site is offered by the Canadian Geological Survey. Twelve earth science topics are presented, including fossils, oil and gas, landforms, and more -- each containing easy-to-do learning activities to be completed with the help of a teacher or parent. One such activity in the Landforms page teaches students how mountains are built by using different colored clays and two books. Each lesson gives directions and a What's Going On? Section that explains the sci
Developed jointly by the Pacific Science Center and the Washington State Dairy Council, Nutrition Cafe offers students three interactive games to explore the world of nutrition. The first game, Nutrient Sleuth, is an entertaining hangman-style game where students try to discover what nutrients different characters are missing based on clues and letter guesses. Another enjoyable offering is Grab A Grape, a Jeopardy-style game where site visitors try to match nutrition-related questions with answe
Learning math : Measurement
This college level course, developed for elementary and middle school teachers, begins with the fundamentals of measurement, then examines standard units in the metric and customary systems. Online workshop sessions cover measurement of a circle, area and volume formulas, angle measurement, and indirect measurement encountered in trigonometry. The final session explores ways to apply these concepts to K-8 classroom teaching. Each of its ten sessions contains video programming, problem-solving ac
Sketching in Nature
Science students will discover the beauty of communing with nature by utilizing a Nature journal during field observations. Nature journaling is a useful skill, independent of whether students consider themselves artists. Sketching from nature is one way to provide open-ended, inquiry-based learning while also bringing art into the process of learning science. This article includes two exercises, contour drawing and an observation activity, to get teachers started in the process of "sketching na

Golden rectangle (grades 6-8)
This virtual manipulative can help students visualize the golden rectangle. It shows how a set of golden rectangles is generated by using the golden ratio (the ratio of the longer side to the shorter side of a golden rectangle) to create smaller golden rectangles within an initial rectangle. The size of the initial rectangle can be varied, and the center of the spiral generated by the applet can be seen. Instructions for using this online manipulative are included on the site, as is a link to th
