NPR: Titanic Baby
This Web site contains an audio file of a story broadcast on National Public Radio earlier this month. The broadcast relates the poignant story of a four-year effort to identify the exhumed body of a 13-month-old child who died in the Titanic disaster. A metal medallion buried with the body serendipitously preserved a bit of the wrist bone, from which forensic scientists could extract mitochondrial DNA and eventually find the child's living relatives.

Thanksgiving Biology
The first Web site (1) is an article from State University of New York College of Environmental Sciences and Forestry. It provides a short, readable introduction to the biology and natural history of wild turkeys in the US. Wild or domesticated, turkey meat is well know for its soporific power. Visitors to the Web site from International Anti-aging Systems (2) can learn all about tryptophan, the amino acid responsible for the post-Thanksgiving dinner nap. Also found in turkey (but much less appe

Revolutionizing Science and Engineering through Cyber-Infrastructure
An expert panel from National Science Foundation's (NSF) Advisory Panel on Cyber-Infrastructure released their final report in January 2003. The report seeks to "evaluate current major investments in cyberinfrastructure and its use, to recommend new areas of emphasis relevant to cyberinfrastructure, and to propose an implementation plan for pursuing them." Several key points are made that promote scientific and engineering research and education through technology. The NSF panel argues that rece

Virtual Fish Tank
This virtual exhibit from the Boston Museum of Science and Nearlife, Inc. allows you to build your own fish based on characteristics like its fear of predators, preference for deep or shallow habitat, and whether it is attracted to bubbles or shiny objects. You can name your fish, watch it interact with others in your own personal tank, and release it into the museum's virtual tank. A simple registration allows users to access the site fully, which includes viewing what happened to your fish whe

CAT (Computerized Axial Tomography) scans
This web page about CAT (computerized axial tomography) scans gives a brief overview of this imaging technique. CAT (or CT) scanning captures a lot of 2-dimensional X-rays that a computer then joins together to generate 3-dimensional images of internal structures. As part of a set of materials about brain scanning technologies, this page mentions what researchers can learn about the brain from CAT scans. Copyright 2005 Eisenhower National Clearinghouse

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

Idea Bank : A Big Bang Lab
The authors of "How Far are the Stars," featured in the February issue of The Science Teacher, showed how the measurement of parallax permits scientists to infer astronomic distances. Give your students the chance to make similar inferences through a free module available online that allows students to scale sizes and distances, and then create models from which they calculate inferences that, in simplified form, give results that astronomers obtained similarly in recent times.
