The Merrimack River served as a living laboratory for the study of ecosystems and earth science for our 5th grade students this week! Our students traveled by boat on the Merrimack to explore how natural and human forces are changing the Merrimack’s Watershed. Students collected water samples, performed water quality tests, and analyzed their data to determine the quality of the water. They also built and tested water filters to assess their ability to clean polluted water and used models to explore how the world’s water is distributed. A great learning experience for all!
