Project WET (Water Education for Teachers) is an international, broad-based water science and education program for formal and informal educators of students in grades K–12. It is part of a larger water resource education program called The Watercourse, located on the campus of Montana State University in Bozeman. This article describes this project, which gives students an understanding of water science and other disciplines; and provides an opportunity for students to learn the skills of structuring questions, designing investigations, drawing conclusions from data, and applying and evaluating their findings.
