In this module students work in small groups with map-based data to learn about watersheds and to find a likely source of pollutants. After a short introduction, students work together to intrepret ther maps provided and to support an argument, stating where the pollutant is coming from, using the map data as evidence. The module provides all the supporting materials needed to run a 90 minute activity.
In this module, students learn: 1) How substances and organisms on land can affect ocean life, 2) How human activities may disrupt ecosystem integrity, to identify the watershed that supplies a river, 3) How to interpret maps of watersheds and land use, and 4) How to combine information from different maps using map scales, and 5) How to make estimates based on map data, and engage in argument from evidence.
