During this project, students will be working cooperatively to create a field guide of trees in the neighborhood near the school. Students will make observations of trees near the school. They will then learn about tree anatomy and physiology. In pairs, students will develop a page on one species of tree for the class field guide. Students will learn how to use a dichotomous key. Finally, the students will develop a dichotomous key, using tree characteristics, to organize the species of trees in the field guide.
