This newly envisioned guide from Project WET contains 12 tried and true lessons that provide a foundation to build water literacy in students. The lessons address all of the Principles of Water LIteracy and include topics such as properties of water, watersheds, water systems, groundwater, ecology, water use, and management of water resources. The learning experiences in this guide include H2Olympics, Blue Planet, A Drop in the Bucket, The Incredible Journey, Seeing Watersheds, Blue River, Color a Watershed, Sum of the Parts, Macroinvertebrate Mayhem, Water for All (formerly 8-4-1), My Water Footprint, and A Plume Problem (formerly A Grave Mistake). Over the next two years, Project WET will roll out three additional guides to encompass the original offerings from WET 2.0.
