Designed to assist teachers whose classes will participate in a residential experience at one of the Conservation Field Centres sponsored by the Metropolitan Toronto and Region Conservation Authority, this pre-planning guide provides necessary details about the underlying philosophy of the program and the roles and responsibilities of the visiting teacher, the school board and the Centre staff. The objectives of the residence program at the Centres are stated: to widen the concept and broaden the understanding of intelligent use of our natural resources; to illustrate conservation as an attitude involving social as well as material processes; to allow practical outdoor application of theory and principles learned in the classroom; and to provide a more intensive experience in group living for student and teacher. Suggestions are offered for determining the tone of the experience, based on the teacher's expectations for the class, and for classroom preparation for the visit. Details are included regarding a pre-planning visit by the teacher to the Field Centre, obtaining parental cooperation and permission, health and safety suggestions, academic preparation, evening recreation time, and procedures to be followed for a guest night during the stay at the Centre.
