In this unit, students will be introduced to what a watershed is and how it relates to their life. They will read about watersheds and threats to a watershed, they will be introduced to new vocabulary, and they will create a watershed model.
This project based learning experience will involve students creating a model of a watershed. This model will include examples of the threats to watersheds which they have been learning about. It will be a workable model that will allow them to alter the landscape to prevent problems such as erosion and runoff from impervious surfaces and farmland fertilizers. Students will work together to analyze data and determine solutions.
The unit includes an introductory Power Point which teaches about the ecosystem of a watershed, readings and comprehension questions about watershed contaminants, directions to create a whole-class working watershed model including all contaminant sources, directions and worksheets for a stream study using macro invertebrates to determine the health of a stream and math sheets and lessons to accompany the unit.
