At Greenland Central School (GCS), the science curriculum is grounded in the Next Generation Science Standards (NGSS) ensuring a coherent, inquiry-driven progression of learning from kindergarten through eighth grade.

In grades K–5, students build a strong foundation in scientific thinking through the Mystery Science program, which fosters curiosity and conceptual understanding through phenomena-driven investigations and active student participation.

In middle school, the science curriculum is anchored by Kessler Science in grades 6–7, providing a strong foundation in Earth, space, life, and physical sciences through NGSS-aligned investigations. Sixth-grade topics include astronomy and Earth systems such as seasons, lunar cycles, galaxies, plate tectonics, weather, and the water cycle. Seventh grade shifts to life science, with in-depth study of human body systems, cells, genetics, ecosystems, biodiversity, and taxonomy, supported by regular dissection experiences. In eighth grade, science is taught by a dedicated science teacher with a strong emphasis on chemistry, including lab safety, density, states and phases of matter, the periodic table, chemical equations, acids and bases, mole and molar relationships, and hands-on laboratory work, including chemical labs and fetal pig dissections. Together, these experiences deepen content knowledge, integrate real-world applications, and reflect the interests and needs of GCS students.
