watersheds and water

Virginia Standards of Learning for Science

Teacher's field guide

What Students Need to Do: Students trace how rainwater moves across land into streams, rivers, lakes, and bays. They explain how people use water and how runoff affects watershed health.
What Mastery Looks Like: Given a simple map, students can identify high land, waterways, and the shared drainage area. They can predict where runoff travels and explain one effect of pollution.
Common Misconceptions: Students may think a watershed is only the river or lake, rather than all the land draining into it. They may assume watershed boundaries follow county or state lines.
How to Assess It: Give students a map with hills, a stream, and a factory. Ask them to trace runoff and explain how a spill could affect downstream water.

Lesson moves

Crumple wax paper into hills, spray colored water onto it, and mark where runoff collects and forms connected waterways.
Ask students to write: How could litter dropped near our school reach a river or bay?
Have teams sort picture cards into watershed sources, water uses, runoff pollutants, and water protection actions.
Map nearby storm drains and use a local map to trace their likely path toward a stream, river, or the Chesapeake Bay.
