Science programs which take place outside the traditional classroom and beyond the usual school hours are listed. The programs (designed for all ages and educational levels and scheduled after school, on Saturdays, evenings, and during summer months) are offered in multidisciplinary science centers located in larger cities, small town museums, regional park centers, coastal field stations, wilderness preserves, and observatories. The list contains three types of programs. Local programs, listed alphabetically within each state, include all programs based at a site such as a museum, science center, zoo, field station or nature preserve. National programs (Boy Scouts, Earthwatch, and Sierra Club among others), listed in a separate section, are usually not connected to a particular building or site and may take place on various campuses, changing sites each year. Types of activities associated with a specific program, name, address, and telephone number of the sponsoring facility, as well as the science area fostered (marine biology, natural history, astronomy, multidisciplinary, among others) are provided for these programs. A list of states sponsoring Junior Academies of Science or other state programs is also provided, with names and addresses found in the state listing. (Author/JN)
