EP Rock Elementary School 4th grade students used their observation skills to learn about the animals that live near and around the St. Croix River. Students discovered the interconnectedness of a river ecosystem, which humans are a part of, and they created an ecosystem model. Community resources, National Park Ranger Jamie Kern and St. Croix River Association Naturalist, Laura Istel taught the lesson.
