The objective of this book is to provide background information and possible teaching approaches to enable teachers to tackle the study of trees confidently. The book should help students to: (1) gain awareness, sensitivity, and basic understanding of trees and their interactions with the plants and animals in their environment; (2) cultivate skills necessary to learn about trees; and (3) develop a concern for trees. Topics include: the basic definition of a tree; the importance of trees; care for trees; interesting facts about trees; parts of a tree; and special functions of tree parts (bark, leaves, flowers, seeds). Suggestions for a wide range of activities suitable for children of different ages make up the greater part of the book. Activities include using the senses, matching attributes of leaves, recording observations, writing poems, doing puzzles, taking measurements, arts and crafts connected with trees, basket weaving, music and sounds made by or by means of trees, identification of different kinds of trees, and designing a tree's food web. A resource list for posters, books, magazines, filmstrips, films, and videos is appended. Each resource entry includes the title/author or publisher, description, grade level, and availability. The book is abundantly illustrated with photographs, drawings, and other graphics. (KR)
