The Department of Biological Sciences offers curricula leading to majors in Biology and Environmental Science.

Biology Program

The objectives of the Biology Program are: (1) to present to the general university student the methods of science and the fundamental principles of biology; (2) to provide students broad foundation training in biology in preparation for professional careers in teaching, medicine, dentistry (and other health professions), biotechnology, industry, government and research; and (3) to provide training in specialized fields as service to programs in Agriculture, Psychology, Health, Home Economics, Kinesiology, and others.

The Biology major may choose from among two degree programs: Bachelor of Arts and Bachelor of Science.

** Recommended minor is CHM, ESC, GEL, MTH, or PHY.
