1.View the surface water animation clip of the Mississippi watershed in the lesson. Compare what is happening in this animation to what occurred to your watershed model.

2.Identify and describe all the ways water moved in your watershed model. Be sure to include headwaters, channels, divides, tributaries, mouth, floodplains, precipitation, and infiltration in your description.
3.How many different watersheds were in your model? How were you able to identify them?
4.Earth’s landscape can change over time. What can happen to a watershed as a result?
5.Based on what you observed in the lab, why does pollution become more than a local problem?
6.In conclusion, how did your prediction of watershed locations match the watersheds in your model?
7.In what ways could you continue to investigate the behavior of surface water and the creation of watersheds? How would further investigation provide research for strategies to solve the spread of water pollution?
