Welcome to the Science Museum of Long Island, where science comes alive! Chartered by the New York State Board of Regents in 1963, SMLI is a not-for-profit science activity center located on the Leeds Pond Preserve in Nassau County. The Science Museum offers enrichment workshops for children on weekdays and during school vacations. We invite teachers and community leaders to learn about our field trips, as well as programs we can bring to your site.  All activities at the Science Museum are pre-registered hands-on science workshops. To experience the Science Museum, you must register for our programs. Our Registrar can be reached at (516) 627-9400 extension 10.
