Objectives: The objective of this lesson is to have students work with a working model of a watershed system that discharges polluted waters into a water basin. Within the watershed various land use areas are affecting the overall quality of the water being emptied into the basin. Students will be given the opportunity to manipulate the management techniques of various land uses to optimize water quality at the mouth of the watershed. Students will be able to hypothesize the effects that new techniques will have on specific pollutants. Students will become aware of the role that all land users have in keeping water quality high. This particular lesson is best suited for the Envirothon Team and the Living Environment Classes.
