The purpose of this 7-12 curriculum is to provide teachers and other educators with classroom lessons and home surveys that are a starting point for understanding five significant environmental issues - water, toxics, energy, transportation, and solid waste/recycling. While each of these environmental issues is complex and has far-reaching implications, the lessons and home surveys can serve as a way for teachers, students and families to begin thinking about these issues in relationship to their own lives. The lesson plan involves two 45-minute lessons and a take home survey. On the first day of the lesson, students are introduced to the five issues and take home a survey to be completed, if possible, with other family members. Students return to school with their completed surveys and discuss the results on the second day of the lesson. This document contains the lesson plans; surveys; a guide to taking action; and fact sheets on "The Automobile", "Energy & Environment," and "Global Warming." (CW)
