Exploring Watersheds

This lesson and activity focus on watersheds and how they operate. A watershed is an area of land that drains into a river system. As the water moves downward, it forms streams and rivers. The channeling and pooling of water is determined by the shape or topography of the land. Water continues to move downward, and rivers may join with lakes or other rivers as they head toward the ocean.


  • Describe the characteristics of a watershed and explain how water flows through a watershed.
  • Demonstrate scientific concepts using a model.
  • Share ideas about science through purposeful conversation in collaborative groups.
  • Evaluate data, claims and personal knowledge through collaborative science discourse.
  • Communicate and defend findings of observations using evidence.
