Project Wet, Project Wild, and Project Learning Tree joined together to create a comprehensive guide to teaching about climate change's impact on Earth's water, trees and wildlife in a holistic way. This document is a matrix of each program’s activities that can be used by educators to teach about climate change in grades K-12.  The matrix lists the title of the activity, which supplemental curriculum guide it is part of, a summary of how to use it, and the corresponding grade level.  Links are provided for many of the activities listed. The resource is a good tool for educators wanting to engage their students in systems thinking activities required to understand the complexities of climate change. It's easy to find the best activity for your audience based on age group and topic. The resource helps educators draw the connections between Earth’s systems and will help students solidify their understanding of the world around them and their role in it. By providing an array of activity types for all learning styles, these activities will help students better understand complex EE topics and be able to protect their environment.
