Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models. They crumple up pieces of paper into model mountain ranges, and then use water-soluble markers to identify the ridges of mountain ranges and the valleys of the watersheds. Next, learners mist the paper with spray bottles, observing how the ink bleeds down the sides of the mountains into the watersheds. The lesson plan includes handouts, background information, and suggested extension activities.
