This site from PBS outlines a lesson plan (intended for grade levels 5-8) concerning gratitude for the earth's diverse ecologies. The page offers a two paragraph Lesson Summary, information about Time Allotment, and several Learning Objectives, including understanding the dual nature of gratitude (appreciation and reciprocity), understanding the positive and negative interactions between humans and the environment, recognizing how gratitude can fuel actions, and recognizing the benefits of diverse perspectives. There are also links to a number of media resources, as well as the nine-step lesson plan itself, which spans two class periods and moves back and forth between lecture, media presentations, and discussion.
