This guide provides information to create and care for a Famous and Historic Trees Living Classroom in which students learn American history and culture in the context of environmental change. The booklet contains 10 hands-on activities that emphasize observation, critical thinking, and teamwork. Worksheets and illustrations provide students with tools to plant and care for trees. Activities 9 and 10 enable the students to create a living classroom in which they plant their historic tree. Activities 1-8 teach about the trees and other ecosystem elements of the Living Classroom by having students write tree stories, use trees to show that observing environmental change can help understand history, measure tree size, learn the values of trees for people, introduce the concepts of habitat and interdependence, study the forest's ecosystem, and examine the importance of trees in urban areas. Sections within each lesson contain the concept, behavioral objectives, subjects integrated, skills developed, prerequisites, time and materials needed, background information, procedures to implement the lesson, and possible extensions. Additional information includes a glossary of 38 terms and a tree selection guide that list tree characteristics. (MDH)
