On Friday, October 13th, 7th and 8th graders joined the crew of The Clearwater Sloop, a 40-year old sailboat that travels the Hudson River, for a morning of environmental and navigation activities. The folksinger and activist Pete Seeger, and others, designed and built The Clearwater in the 1970s to help raise public awareness about the need to clean up the Hudson River. The 45 middle school students helped to raise the sails, learned how to read a navigation chart, studied the river’s fish (especially one species called the Hog-Choker), and they considered the problem of micro-plastic pollution by measuring water turbidity. The weather was great for the few hours we sailed on the historic and beautiful Hudson. Departing from the 79th Street Boat Basin in Manhattan, the students had breathtaking views of Manhattan landmarks. It was a great day of education, maritime activities and fun! The day supported the 7th Grade’s Science and Environmental Awareness curriculum regarding water and its distribution on earth.
