Students with matching leaves should be grouped together and asked to identify their type of tree with the aid of a tree identification guide. Have students press the leaves. Repeat the exercise in a different season and have students compare leaves from different seasons. In the Life of a Tree. Locate a tree and observe it for an entire school year.
Record changes on a weekly basis.
Keep records of changes in leaf color. When leaves are gone, note any nests or animal activity. Note when buds first appear and when leaves emerge. Record leaf development. Using the same leaves, ask each student to study his or her leaf carefully.
