The Science Department believes that the study of science is vital to the development of intellectual curiosity and analytical thinking. Students learn to see science as a process as well as a body of knowledge about the natural world. 

It is the philosophy of the Science Department that students benefit from exposure to each of the three sciences: biology, chemistry, and physics. The Science Department does not award credit for science courses taken during the summer. Furthermore, Science courses taken over the summer will not count toward our listed prerequisites.
