Children's park programs in and near the District of Columbia are listed in this directory which is designed for people who plan field trips for children and people interested in developing similar programs. The directory describes more than 80 programs conducted in 30 parks and gives age ranges, schedules, and phone numbers for obtaining further information. Most programs stress active participation; most provide opportunities to study nature and the environment, to participate in the creative arts, or to learn about early American life. Activities include nature walks, films, theater for and with children, a wide variety of crafts, a solar energy workshop, and an overnight experience as an 1890s farm hand. At Manassas Battlefield Park and Antietam Battlefield, children (and adults) learn about the Civil War through hands on demonstrations of muskets and cannons, walks through battle sites, and evening campfires with Civil War songs, stories, and refreshments. Program complexity ranges from guided tours to a gardening project in which student involvement begins with spring planting and extends through fall harvest. Several programs provide teaching guides and classroom materials to help children prepare for and review their trip. The directory concludes with suggestions for working with children in experiential programs and a bibliography for program leaders. (JH)
