Watershed Connections Lesson Plans

While meeting multiple environmental literacy and curriculum requirements (listed in the lesson plan), students can use the model to investigate numerous topics, including historical land use, water pollution, and the use of best management practices. From grades 2-12, teachers are finding these models support lessons in the water cycle, ecology, sociology, and more.

Objectives—Students will be able to:

  • Discuss why a watershed perspective is needed to restore or protect water quality.
  • Describe how different land uses affect the water cycle.
  • Describe how impervious surfaces affect stream ecosystems.
  • List sustainable practices students can undertake to reduce stormwater runoff.
