Middle-school students from a Massachusetts Montessori school are studying science the way that scientists do through a marine-ecology course in Duxbury Bay. Students conducted research on water pollution and then began their experiments into the field to test their hypotheses. They will also work together to build a small wooden boat. Both hands-on activities help make learning more interesting to students, said their teachers. They "motivate the more theoretical studies. They make the kids much more receptive to the course work," the author of the course said.
