Describing the Union 58 Experimental Schools Program (ESP) in northern, rural New Hampshire, this curriculum guide presents the concept of "proximity congruency" as a means for developing secondary level student sensory awareness of the environment in outdoor and/or environmental education procedures. Proximity congruency is defined as a state of harmony existant between two or more animate and/or inanimate objects wherein there is a natural state of interaction. Field trips, nature walks, and site studies are among the outdoor education strategies mentioned in terms of achieving proximity congruency. Additionally, this guide presents four sample environmental education sensory lessons in a format that includes the following: educational focus (land use study, trees, and seashore environment); the concept to be explored; grade range; purpose; and numerous exemplary student activities. When necessary, the lesson also includes specific equipment and procedural needs. (JC)
