You don't need to be a detective to find global change and environmental lesson plans for grades K-8. A teacher designed this web site specifically for teachers to access, view, and print lessons during one planning period using their school's internet connection. Within each topic, the sources of the lessons are cited alphabetically. The lessons are arranged by grade level within each source. If teacher background information is cited by the source for a particular lesson, it is listed after the lesson. If a Teacher Guide is provided for a source, it is listed at the end of the source.
