As part of their year-long study of Vermont, our 2/3 Stem students are learning about wetlands and the Lake Champlain Basin. They tested samples from McCabe Brook, located just behind Vermont Day School, to measure phosphorous, nitrates, dissolved oxygen and turbidity. They also did an experiment to demonstrate how wetlands act as a filter for taking out pollutants and nutrients, as water flows from the Brook into the Lake. The class has decided to create an educational video to share their findings with others and to provide suggestions for reducing pollution in our watershed. Stay tuned!
