Exploration of the Earth's Magnetosphere
A thorough tutorial on the Earth's magnetosphere by D. P. Stern and M. Peredo. This is an excellent resource for undergraduates, science teachers, and advanced high school physics students. Includes interesting information about the history of space physics research. Provides a useful glossary, with hyperlinked definitions in the text. Amply illustrated. The authors are both space physicists at NASA's Goddard Space Flight Center.

International Solar Terrestrial Physics (ISTP) Web Site
This is the home page for the NASA ISTP program. It includes a public outreach page that has lots of good information about geospace, the scientists who study it, and the ISTP spacecraft missions. Provides resources for students and teachers.

Oulu Space Physics Textbook
A project of the Space Research Group at the University of Oulu in Finland, this extensive on-line textbook addresses the following topics: basic plasma physics; the Sun and interplanetary medium, the Earth's magnetosphere and ionosphere; coupling processes; phenomena such as the aurora, cosmic rays, and space weather; and space instrumentation and analysis techniques. A useful resource, particularly for undergraduates. The presentation is probably a bit too technical for a general audience. The URL for the Oulu textbook homepage is

Science Education Gateway (SEGway)
SEGway is a NASA-funded education and public outreach effort led by the University of California at Berkeley. The SEGway site provides lesson plans and some self-guided lessons on a number of topics in earth and space science, including the aurora, sunspots, the electromagnetic spectrum, astronomical observation at non-visible wavelengths, and many more. A wonderful resource for teachers to locate classroom activities for use in their K-12 classrooms.

The Space Science Education/Public Outreach Site of NASA's Office of Space Science
A directory of education and public outreach sites prepared by NASA's Office of Space Science.

Space Science Institute
The Space Science Institute (SSI) web site contains information on a variety of topics of interest to researchers, educators, and the general public, including: space weather, travelling exhibits (Electric Space, Marsquest), downloadable curricula, and education workshops for scientists. SSI is a non-profit corporation whose mission is to improve communication among scientists, educators, and the general public by combining space science research with science education.

Space Science News
An attractive, user-friendly on-line "newspaper" sponsored by the Space Sciences Laboratory at NASA's Marshall Space Flight Center. Every "issue" contains several recent headline stories on topics in space physics, astrophysics, and earth science. The stories are clearly written, provide good background information, and are amply illustrated with colorful and well-chosen graphics (including movies and animation). Links to many other related sites, including a featured "site of the day," are provided.

The Sun-Earth Connection Education Forum
The education and public outreach site for NASA's Sun-Earth Connection theme, developed jointly by NASA's Goddard Space Flight Center and the Space Science Laboratory of the University of California at Berkeley. The site offers a tutorial on the Sun-Earth Connection, links to space science mission pages, and a very nice "resource index" with links to other Web sites.

Windows to the Universe
"Windows to the Universe" is an innovative, graphics-rich Web site offering a nearly comprehensive treatment of the Earth and Space Sciences at three levels of content, corresponding to upper elementary, middle, and high school levels. The site also features interdisciplinary arts and humanities content relevant to the scientific topics. A supplementary CD is available. "Windows" was developed at the University of Michigan with NASA funding.
