Science Department Mission Statement

The mission of the Science Department at Brophy College Preparatory is to develop critical thinkers who understand the ethical responsibility that comes with scientific knowledge. Students are encouraged to take classes in many fields of science so that they will understand the interrelated nature of the scientific disciplines and discover that the scientific method is common to all areas of science. We seek to ensure that our students have the scientific knowledge to become responsible citizens in today’s advancing society.

There are many opportunities in the science department for students to advance to honors or advanced placement level classes once they demonstrate proficiency in the mathematic and scientific prerequisite skills needed for success in these courses. Three years of laboratory classes are required for graduation but most students choose to take elective courses in science beyond the minimum requirements.
