The chemistry major is designed to guide students toward understanding the principles underlying the composition, structure, and properties of substances—both natural and man-made—and the transformations they
undergo. The program emphasizes helping students become knowledgeable observers and independent, imaginative problem-solvers, using state-of-the-art equipment in a laboratory setting. 

The chemistry program offers three degrees of Bachelor of Science with the emphases listed below: 

  1. B.S. Major in Chemistry with Chemical Careers Emphasis 
  2. B.S. Major in Chemistry with Health Sciences Emphasis 
  3. B.S. Major in Chemistry with Material Science Emphasis

The B.S. in Chemistry with Chemical Careers Emphasis is designed primarily for students who wish to pursue graduate studies within the chemical sciences or seek employment in chemistry-related fields. Students planning to enter health-allied professional schools may choose a B.S. in Chemistry with Health Sciences Emphasis or B.S. in Chemistry with Material Science Emphasis degree. Further information and course requirements are listed under each emphasis. 

  • Students may take CHM 105, CHM 110, MTH 210, and PHY 240/241 to satisfy core requirements.
  • CHM 105 is not required for students who enter Lyon College with a score of 25 or better on the ACT mathematics section (or equivalent SAT score) and a grade of "C" or better in high school chemistry.

NOTE: To graduate with a Bachelor of Arts or Bachelor of Science degree from Lyon College, students must successfully complete a minimum of 120 semester credit hours comprising of our required Core curriculum (44-48 hours), the requirements of at least one major (credit hours vary per major), and a selection of our Liberal Arts electives. They must also earn at least a 2.00 cumulative grade point average for all work taken at Lyon College and a 2.00 cumulative grade point average in their major, minor, and concentration.
