Outdoor education is an informal method of teaching and learning which offers opportunities for elementary school students, regardless of intellectual abilities, to learn about and appreciate their environment and acquire skills with which to enjoy a lifetime of creative, productive, and healthful living. Outdoor education can enrich, vitalize, and complement all content areas of school curriculum by means of first-hand observation and direct experience out-of-doors. School grounds, regardless of locale, can afford learning opportunities. This publication discusses the need for and focus of outdoor education, outlines six school ground activities adaptable to any elementary grade level, and provides specific language arts, social studies, science, health, mathematics, art, and music projects for each outdoor activity. The outdoor activities include: marking shadows at different time intervals; collecting insects and other animals; observing the flagpole; observing a partly cloudy sky; and observing birds near feeders or shrubs. Interdisciplinary activities suggested from a visit to the school parking lot include composing words from license plate letters, determining distances to capital cities of states represented by cars in the parking lot, suggesting parking lot safety rules, computing parking lot size, designing a car using basic shapes and colors, and composing a song or rhythmic reading.
