The Science Barge is a sustainable urban farm and agricultural center owned by Groundwork Hudson Valley since October 2008. The Science Barge, floating greenhouse on the Hudson River, grows an abundance of fresh produce including tomatoes, melons, popcorn, peppers, eggplant, and lettuce with zero net carbon emissions, zero pesticides, and zero runoff. All of the energy needed to power the Barge is generated by solar panels, wind turbines, and biofuels while the hydroponic greenhouse is irrigated solely by collected rainwater, thus operating completely “off the grid.” It is one of the first fully functioning demonstrations of renewable energy supporting sustainable food production in New York. It is currently docked in downtown Yonkers just north of the Yonkers Pier.

The Science Barge is open for weekday educational programs and field trips for schools, camps, and other groups from April through the beginning of October.

Barge Tour

The Science Barge tour is an engaging and interactive experience students will never forget.


Example Itinerary


Educators greet class off of the barge outside of the entrance gate and go over the on-barge rules and split the students into 2–4 even groups.



Educators will seat students on the barge and give a short introduction of the space.



Educators will take individual groups of students and rotate them throughout active barge stations; station examples include nutrient cycling, soilless growing systems, greenroof, energy systems, river outlook, germination table, and more.



This time would be used for an activity and/or *lunch program.

*We do NOT provide lunch.



For 90 minute and 2 hour programs we offer the opportunity to add an activity to your 1 hour tour of the Science Barge. These hands-on activities further the students’ understanding of sustainability through interactive teamwork and fun!
