The Science Department strives to nurture a spirit of inquiry as we guide students in the study of the natural and physical sciences. All courses are laboratory and/or field-based, emphasizing the process of science in addition to core content knowledge of the disciplines. The history of science and scientific literature capture the implications of science in society, and science courses thus draw from authentic accounts of scientists’ practice. 
The science program begins with physics in 9th grade. In grades 10 through 12, students are expected to take year-long courses in chemistry and biology. Students in 11th and 12th grade, with attention to pre- and co-requisites and appropriate approval, may elect to enroll in Advanced Placement courses in physics, chemistry, or biology or choose to engage in a topical science elective courses. 
North Shore Country Day School is a junior kindergarten through 12th grade, college-preparatory school founded in Winnetka, Illinois in 1919.  With rigorous academic pursuit as the cornerstone, North Shore provides many opportunities for all students to excel – in the classroom and the laboratory, on the stage and the playing field, in their communities and beyond.
