The NanoEnvironmental Engineering for Teachers (NEET) course is designed to serve AP environmental science teachers. The purpose of the program is to increase the content knowledge of educators and empower them to implement rigorous project-based engineering activities on water sustainability. We will accomplish this goal by mastering environmental science content and exploring the most effective proven "best practices" in educational pedagogy. Every teacher participant is expected to engage in active discussions and analysis. This requires that every teacher participant complete and critically analyze readings and content activities and evaluate their classroom practices.
