The Science Department’s goals for our students are to provide a solid foundation for college-level work, to provide a rigorous and extensive laboratory experience and to develop crucial reasoning skills. The department also strives to instill a respect for nature, as well as an appreciation for its beauty, complexity and diversity. Our efforts are directed to lead students to be responsible steward of the natural world. We are convinced that the insights of science brings our students closer to the truth and to the Creator of truth and that a Catholic Christian student with a profound understanding of science will mature with enriched religious beliefs.


There are many offerings in various disciplines on many levels, from college preparatory level to honors, advanced honors and AP courses. We offer AP Biology for freshmen and for seniors, AP chemistry, AP environmental science, AP physics 1 and 2, and AP physics C.
