Science Department course offerings give students the opportunity to learn more about the world around them and their interaction with it. Students experience a wide range of content as well as demonstrate capacity for observation, synthesis and analysis of ideas, use of equipment, and effective communication. The most common four-year sequence from 9th through 12th grade is Advanced Earth Science, Biology, Chemistry, and Physics. Subject to meeting prerequisites, this sequence may be altered. In addition, students may find additional challenges of interest in elective and advanced placement courses. At the same time, Ecology and Conceptual Physics are available for those requiring a less stringent science program. Many students take more than one science course during one or more years in order to fulfill personal interests and needs.
