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 elementary level (grades four through six) 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. Some of the outdoor education strategies for achieving proximity congruency mentioned are field trips, nature walks, and site studies. Additionally, this guide presents eight sample environmental education sensory lessons in a format that includes the following: educational focus (earth's resources, plants and animals, recreation, metric measure, and/or measurement); the concept to be explored; grade range; purpose; and numerous exemplary student activities.
