The Thomas Jefferson National Accelerator Facility, or the Jefferson Lab, is funded in part by the Department of Energy and was "built to probe the nucleus of the atom to learn more about the quark structure of matter." Of special interest to researchers will be the extensive experiments section with experiments organized by hall, by status in terms of approval and completion, by proposals, and by physics category. Descriptions of individual experiments include summaries (.ps), participating institutions, experiment titles, and a letter grade rating. The publications section of the site contains a catalog with online publications (.pdf) organized by year, and a complete searchable bibliographic list with downloadable technical documents organized by year. Also, for educators, the Science Education at Jefferson Lab Page ( http://www.jlab.org/services/pced/?students/teachers) lists internships, special events, and classroom resources including a tour of the atom, a periodic table of elements, and an element flashcard game.
