This activity is about making observations of a tree over time. Choose a tree that is near the school and one that changes through the year. A deciduous tree—one that loses its leaves—makes the best subject. Visit the tree and repeat this activity often to observe the many changes throughout the seasons. A materials list, internet resources, standards, and safety practices are provided. This book selection also includes the Table of Contents, Preface, About the Editors, Introduction, Simple Graphing for Young Children, Science Teaching Boards and Boxes, Basic Materials List, and Index.
