The Green Roof Environmental Literacy Laboratory (GELL) at PS 41 establishes a living lab to boost environmental literacy and enable students to learn about their stewardship role in the health of the planet. Students also use GELL for hands on lessons in chemistry, biology, mathematics, nutrition and aesthetics. The vegetated rooftop provides habitat for birds, bats, butterflies and other insects, reduces the city’s carbon footprint and mitigates storm water runoff. New York Green Roofs consulted with Jonathan Rose Companies on the design and oversaw installation of the project. Ongoing maintenance is also provided by New York Green Roofs and is supported directly by PS 41 PTA.
