The department offers the student the opportunity of gaining a broad-based foundation in the respective chemical, physical, or earth science field by providing fundamental training in the application of chemical and physical principles and introduces the liberal arts student to a basic understanding of chemistry, physics, or earth science. The course of study is designed to prepare the student for teaching. Industrial work, and graduate education.

Biochemistry and Molecular Biology Interdisciplinary Major

Bachelor of Arts

The major in Biochemistry and Molecular Biology (BIMB) requires a minimum of 65 hours of science and mathematics. Because this degree is interdisciplinary in nature, no minor is required.

Bachelor of Science

The major in Biochemistry and Molecular Biology (BIMB) requires a minimum of 73 hours of science and mathematics Because this degree is interdisciplinary in nature, no minor is required.


Bachelor of Arts

The Chemistry major requires a minimum of 33 semester hours of Chemistry. A minor is recommended in a physical or life science, or mathematics.

Bachelor of Science

The Chemistry major requires a minimum of 41 semester hours of Chemistry. Students pursuing the BS degree must minor in one of the following fields: biology, computer science, geology, mathematics, environmental science, and physics. The student preparing for graduate study in chemistry should take additional work in mathematics and physics.

Earth Science

The Environmental Science Minor is designed for the student seeking a B.S. or B.A. degree wishing to minor in the environmental sciences. The minor establishes a strong foundational understanding of the environmental sciences and their application in modern society. Students may choose from a geology track or a biology track to tailor to their interests. Environmental science minors must take ENVS 1111, 1311, 4350, and ENVM 4320, 4340. Students must complete either Track 1 (Geology) requiring GEOL 1103, 1303, and 3311 or Track 2 (Biology) requiring BIOL 1307 and 3410. Students majoring in biology are required to take the geology track to ensure a more interdisciplinary understanding of the field.

The Geology minor requires a minimum of 19 semester hours of Geology, including GEOL 1303/1103, 1411, 2410, 3405 or 4410, and three upper-level hours.


Physical Science

Objectives - Physical Science courses are designed to give the student an understanding of the physical universe. Note: PHSC 3101, 3301 and 3320 can be used as partial fulfillment of the science requirement in the university General Education curriculum.


The Physics minor requires a minimum of 24 semester hours of Physics, including PHYS 1320/1120, 1321/1121, 2410, 3320, 3340, 4310, and three credits of 4090.
