Throughout the discussion ask the students to explain why they labelled certain trees the way they did. Stress the importance of the role each tree plays in the environment, and point out that it is possible for one tree to play many roles. For example, all trees are Carol Catchment Trees and Oscar Oxygen Trees. See suggested question cards in Resource Sheet 5. Students can also check their understanding of the roles of these characters with an on-line activity on this web site.
Students select photographs of trees to match the tree character descriptions.
