The science curriculum is based on the New York Learning Standards for Science (NYSSLS). Core ideas build on one another as students progress through grade levels and are grouped into the following four domains: Physical, Life, Earth and Space, and Engineering. North Merrick enhances the program by integrating STEM (Science, Technology, Engineering, and Math) instruction at all grade levels. The North Merrick science program also incorporates computer coding and Lego Robotics units at various grade levels. To further expand on core ideas and cross-cutting concepts, students in first grade will hatch chicks as part of an Embryology unit, second graders will take trips to the beach to collect marine life as part of a Marine Life unit, fourth graders will manipulate stream tables as part of a problem-based learning unit culminating with a "Save the Beach" activity, and sixth graders will delve into engineering and physics as part of a Buildings and Structures unit. North Merrick has most recently adopted the National Geographic Science program to further immerse students in real-world science practices.
