Leaf activities can provide a means of using basic concepts of outdoor education to learn in elementary level subject areas. Equipment needed includes leaves, a clipboard with paper, and a pencil. A bag of leaves may be brought into the classroom if weather conditions or time do not permit going outdoors. Each student should pick a leaf, examine it carefully, then describe it to a partner or in a group of three. Vocabulary development is encouraged with use of such words as "leaf,""stem,""vein," and adjectives describing shape and color. Possible learning areas include identifying types of trees by their leaves; language arts (involving oral activities, factual writing, fictional writing, and poetry about leaves); art (using leaves in art projects); music (listening to leaf sounds, finding songs about leaves, and listening to musical compositions that suggest trees and leaves); mathematics (measuring, discussing, counting, and sorting leaves); science (observing and comparing color, structure, size, shape, and odor of leaves); the senses (observing visual, tactile, sound, and scent aspects of leaves); and understanding a leaf (including scientific explanations of the functions of leaves). Four general concepts/aims of outdoor education are given. (Author/MH)
