This document outlines a 12-lesson plan to teach students about the impact humans are having on Earth. The plan uses an inquiry-based "Five E's" approach of engage, explore, explain, elaborate, and evaluate. Lessons cover topics like water, pollution, recycling, deforestation, climate change, and raising awareness. Formative and self-assessments are built into the lessons. The overarching goals are for students to understand our effect on the planet and ways to influence positive change.
