Calvin’s bachelor of science in biology places a strong emphasis on research. This is the ideal program if you are interested in pursuing an advanced degree in biology, medicine or scientific research. The program gives you a broad foundation in the field of biology and then offers courses in many sub-fields so you can tailor the program to your specific interests.

Calvin’s connections with the local, national and global scientific community open up tremendous experiential learning opportunities for you. Research facilities and equipment, funded in part by numerous grants from the National Science Foundation, offer you the tools you need to excel in this field.

  • Take four introductory courses to give you a broad base in biology.

  • Choose upper level courses to fit your specific interests in the field of biology.

  • Participate in a 300-level research course.

  • Take a capstone course to explore what it means to be both a Christian and a scientist.

You must complete three courses in biology with honors, submit and honors thesis, and earn a minimum 3.5 GPA in the major to satisfy the college’s honors program.

  1. From the biology major’s required courses, one will normally be the honors section of 160 or 161. Alternatively, this requirement could be met by contracting with an instructor for honors credit in BIOL 141 or 230.

  2. The second honors course must be taken from courses numbered 313-364 (excluding 354), the details of which will be worked out by the student and instructor at the time that the student registers for the course.

  3. The third course requirement is the completion with honors of an upper-level research course (Biology 354, 385 or 399). Normally the investigative research conducted in one of these courses will be reported as a scientific research paper, which will constitute the honors thesis and as a public presentation to a scientific audience.
