To identify the (1) watershed you live in, (2) source of water used at home, and (3) pathway of surface runoff in your watershed.
Look at the watershed maps of your state to answer the following questions:
Water flows from high elevations to low elevations. In a stream or river, water flows from upstream to downstream.
10. What path do you think water follows in your watershed? With your finger, trace the pathway of water draining from the high elevations in your watershed. (Use the large map on the poster and place an arrow on the map to show the direction water flows.)
11. What patterns do the rivers and streams create in your watershed? Sketch the pattern of drainage. Explain what causes these patterns
12. If gasoline spilled into the river upstream from your town, what path do you think the gasoline would take based on your knowledge of river pathways in your watershed? Refer to the watershed map before writing your explanation here.
Investigate methods used to identify, track, and monitor river pollution and describe a method that scientists would use to determine how long it would take a pollutant in a river to travel downstream to the next town.
