At CSG, the Science Department uses an inquiry approach to learning by using cooperative experiences to engage students in lab activities and experiments. When given a problem, students identify variables and develop procedures. They perform tests, collect and analyze data, and make charts and graphs to help formulate conclusions. Students experience guided inquiry where they are given a set of objectives, a set of safe websites for them to explore, and a rubric to clarify the expectations beyond the traditional laboratory experience. In advanced courses, students experience true inquiry approach: they are given a problem and resources to utilize to design and conduct experiments to test their hypothesis. As a summative assessment, students present their findings in post-inquiry sessions with peer review.

The Science Department strives to help students realize that science is fascinating, fun, and rewarding; understand that scientific discovery is an ongoing, ever broadening, self-correcting search for answers, and that any one discovery leads to further questions and experimentation rather than an absolute or ultimate truth; appreciate how the cooperative nature of the current scientific enterprise works; be able to make clear judgments regarding their roles in the today's technological and competitive world;­­­­ and learn the fundamental facts, concepts, laboratory and reasoning skills that are basic to further formal study in the individual scientific disciplines.
