First, we had a speaker from the Virginia Department of Forestry come talk to us about the importance of forests in the protection of the Chesapeake Bay watershed. She did a demonstration about polluted water and showed how trees and vegetation near banks of rivers (and other water sources) can help reduce pollution.
To follow up with her talk, we made our own "polluted" water and built water filters out of various materials to see which ones would function best as filters.
Second, we had a speaker from the Hanover-Caroline Soil and Water Conservation District who talked more about our watershed address, watersheds in general, and the importance of soil as a natural resource. She did two demonstrations that really hit home the concept of a watershed.
