Students who major in Biology at Gustavus Adolphus College investigate all the major fields of the life sciences—from how molecules and genes work to how organisms respond as well as the flow of nutrients through an ecosystem. Students have the opportunity to expand the boundaries of scientific knowledge by engaging in research in courses taught by a broadly trained group of committed faculty, and in optional intensive research collaborations with a faculty mentor.
While encouraging in-depth preparation for graduate and professional studies, the Biology Department places a strong emphasis on breadth of understanding. All students will complete a core introductory Biology sequence of courses (BIO-101, Principles; 102, Organismal; 201, Cell & Molecular; and 202, Ecology, Evolution & Behavior) augmented with courses in Chemistry and Mathematics. This core sequence is structured to prepare students for advanced scientific studies while introducing them to a broad foundation. Two Chemistry courses (CHE-107, Principles; and 141, Organic 1) must be taken prior to BIO-201 and BIO-202. Level II courses have a prerequisite of BIO-101 and BIO-102, while Level III courses require completion of the four-course Biology core and two courses in Chemistry.
The Biology Department encourages its students to study abroad. Many programs offer courses that will transfer back as part of Biology major/minor credit, includ- ing these from the past few years: Lancaster University (England), The University of Cape Town (South Africa), University College Cork (Ireland), The University of Aberdeen (Scotland), The Universities of Melbourne and Queensland (Australia), and non-university-based programs in Costa Rica, Tanzania, Denmark, and Namibia. Interim Experience courses also encourage international experiences, with recent Biology offerings in Tanzania, Ecuador, Mexico, Bolivia, and Guatemala.
Sequential courses and courses with prerequisites require that prior courses have been completed with a grade of C or better (with the exception of BIO-101 and CHE-107 which must be graded C- or better) for all students.
Biology Major: Eight regular semester courses in Biology, plus CHE-107 and CHE- 141, and one course in Calculus or Statistics. The Biology courses must include BIO-101, BIO-102, BIO-201, BIO-202, and four additional courses level II or above selected in consultation with a faculty advisor. Three of these additional courses must be level III. A GPA of 2.0 or higher is required from all courses counted toward the major for successful completion of the major.
CHE-255, GEO-241, or PSY-260 may be used as a level II course toward the major. Additionally, in the years it is offered, a comprehensive departmental program assessment exam is required of all graduating majors.
Life Science Teaching Major: Two Life Science Teaching licenses are possible through the state of Minnesota: grades 5 through 8 and 9 through 12 licen- sure. However, it is recommended that candidates complete both licenses to be competitive for teaching positions. (The addition of three courses, PHY-102, GEO- 108, and GEO-111, will add the 5-8 General Science license to the 9-12 Life Science license.)
The Life Science Teaching Major for grades 9-12 requires the same course as the Biology major, with BIO-374, Genetics, as one of the required level III Biology courses, In addition to the Biology, Chemistry, and Mathematics courses required for the Biology major, the core Secondary Education courses must be completed as well as EDU-248. A GPA of 2.0 or higher is required from all courses counted toward the major for successful completion of the major. A GPA of 2.0 or higher is required from all courses counted toward the major for successful completion of the major.
The General Science License for grades 5-8 is required to teach Life Science at the middle school level. The 5-8 license requires BIO-101 and 102, a Physics sequence (either PHY-120/122 and PHY-170/172, or IEX PHY-100), CHE-107, GEO-108 and GEO- 111, PHY-102, and EDU-248, in addition to the required Elementary or Secondary Education coursework.
Please see the Education Department section of this bulletin or the department website for a listing of the Education courses required.
Biochemistry and Molecular Biology Major: See Biochemistry and Molecular Biology section of catalog.
Neuroscience Minor: See Neuroscience section of the catalog.
Departmental Honors in Biology: The Department has an Honors Program. Please consult the Biology Handbook or Biology website for details.
Petitions: Students intending to major or minor but not meeting the GPA requirements stated above may retake select courses and improve grades to address the requirement; there is no option to petition this requirement.
Students not intending to major in Biology who want to take a core course out of sequence may do so by petition to the department. Petitioners must discuss their academic plans with a member of the department before submission of the petition. Approval of the petition allows enrollment in the core course only. Petition forms are available in the departmental office or on the Biology website.
All advanced courses (Level II and III) retain the prerequisites stated above. Non-majors may petition exception to the prerequisites, but the following three criteria must be met prior to enrollment:
- Completion of four science courses with a laboratory component. This is to ensure the critical skills required for advanced laboratory work.
- A minimum grade point average of 3.0 in the four science courses.
- Adequate space exists after enrolling Biology majors, who have priority for advanced courses.
Preparation for Graduate School
Biology majors preparing for graduate school are urged to consult with a faculty advisor as soon as possible in their academic career. Careful selection of courses beyond the core is important for preparation toward a specific sub-discipline. Most students preparing for graduate work complete additional courses in calculus, statistics, chemistry, and physics. Plans should be made to take the general and advanced tests of the Graduate Record Exam (GRE) at the end of the junior or early in the senior year.
