Developed by the The National Health Museum - includes definitions, activities, and teacher information.

Astro-Venture

NASA (National Aeronautics and Space Administration)
This multimedia website deals with NASA careers and astrobiology research. The concept is to search for and design a habitable planet. Students enter training, are quizzed on their knowledge, and adjust the features of potentially habitable planets to see what makes a planet habitable and why. The recording of student observations ties this activity to the basics of the scientific process. (From HOKU Newsletter)

Checklist of Amphibian Species and Identification Guide

U.S. Geological Survey (USGS)
This site provides a browsable "checklist of all amphibian species and subspecies currently recognized in North America north of Mexico." Salamanders, newts, frogs, and toads are briefly described in their adult phase; many entries include photos and range maps showing where a species is found. There is also an annotated list of amphibian and reptile identification Web sites. From the U.S.Geological Survey (USGS) Northern Prairie Wildlife Research Center.

Electronic Flash Cards

These flashcards will help you learn and practice many aspects of organic chemistry.

MicroAngela's Electron Microscope Image Gallery

This browsable site explores the world of "microspace" with whimsically annotated and colorized images. See close-up views of both familiar everyday insects and those rarely seen, diverse body cells, parasites, oceanic creatures, and much more. The images are viewed by the use of scanning electron microscopes (SEM) and transmission electron microscopes (TEM). See also the Virtual Library's Microscopy to further explore the incredible tools of the unseen world of microspace and the numerous resources on all its aspects.

Powers Of Ten

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.

Public Health Image Library

Although created to support people in the public health arena, this database has a variety of images that can be used in high school health and life science classes. Use the search feature on the home page, or click the search to browse the categories available. A search for body parts (such as lung) was not very helpful, but a search for disease returned hundreds of slide and autopsy images.

The Stem Cell Debate

This special presentation from CNN covers the pros and cons of the stem cell debate from the ethical, political, and scientific points of view. An animated explanation is presented on how stem cells are harvested. Evidence of promises of treating neurological diseases is offered by researchers.

Understanding Evolution

A resource for teaching about evolution from University of California Museum of Paleontology.

WhaleNet

This interactive educational web site focuses on whales and marine research. Take the WhaleNet Tour to acquaint yourself with the resources available at this website, such as the Satellite Tagging Observation Program and What's It? (an identification activity).

Willo, the dinosaur with a heart

The website has been established to present information about the unique fossil, reported in the April 21, 2000 issue of the journal Science.
