This interdisciplinary, four-lesson module uses project- and problem-based learning to help students create a highly efficient dam that has a minimal impact on the environment. Students will explore the use of natural resources to provide energy needs, specifically hydropower, while exploring the workings of watermills, wind turbines, and generators to help build an understanding of the effects of dams. In creating their dam, they will learn about the various types of alternative hydropower sources, including wave and tidal power, and track the progress of electrification in the U.S. on a timeline; alongside researching the positive and negative consequences of hydropower. To support this goal, students will do the following: The is anchored in the Next Generation Science Standards, the Common Core State Standards, and the Framework for 21st Century Learning. In-depth and flexible, can be used as a whole unit or in part to meet the needs of districts, schools, and teachers who are charting a course toward an integrated STEM approach.
