This publication is part of a curriculum series developed by the Regional Marine Science Project for use by teachers and administrators. Field work and field trips, being advocated as an integral part of the curriculum, are explained at length. The rationale and techniques of field ecology are offered relating them to the need for field trips and how to plan field experiences. A sample outdoor class is outlined together with a discussion of how to put a field trip program in the school system. This last part considers the design of an integrated program, implementation of the program, the nature of a field trip, and a field trip center. This work was prepared under an ESEA Title III contract. (BL)
