The second of a three-unit lesson plan, this focuses on how human-made structures affect watersheds. Using watershed models that were built during the first unit, junior geologists now place buildings, dams, or levees into the models and make observations about the movement of water. Although intensive with regards to materials and time, these lessons are extremely valuable for your earth science learners. The 16-page write-up provides everything you need to carry out this project with your class.
