The programs of the department are designed to introduce students to unifying concepts and broad issues in biology, and to provide the opportunity for in-depth inquiry into topics of particular interest through coursework and independent study. Introductory- and intermediate-level courses examine the structures and functions of living systems at all levels of organization, from molecules, cells and organisms to populations. Advanced courses encourage the student to gain proficiency in the critical reading of research literature, leading to the development, defense and presentation of a senior paper. In addition, there are opportunities for independent research projects with faculty.
Course requirements for a major in biology include two semesters of introductory biology, 101 and 102 (or 103 plus either 101 or 102, with the department’s permission); six courses at the 200 and 300 level (excluding 390-398), of which at least three must be laboratory courses; and one senior seminar course (390-395, or 398). Two semesters of supervised laboratory research, 403, may be substituted for one of the required laboratory courses. In addition, two semester courses in general chemistry and three additional semester courses in physics, chemistry, geology, mathematics, computer science, psychology (courses that satisfy the Division II requirement) or statistics are required for all majors. Selection of these three science courses needs to be done in consultation with the student’s major adviser and be approved by the department. Students interested in pursuing graduate studies or medical school are encouraged to take two semesters each of physics and organic chemistry.
Students with a score of 4 or 5 on their Advanced Placement examinations, or equivalent International Baccalaureate scores, will receive divisional credit only; they may not be used for the major in biology. A student wishing to enter biology courses at the 200 level without having taken Biology 101 and 102 must take and pass the departmental placement exam. Courses in other departments may be substituted for major requirements with the department’s permission.
The honors distinction requires maintaining a course average of 3.7 in the major and participating in departmental activities and events. Final selection for honors is made by the biology faculty from the list of eligible students.
A minor in biology consists of six semester courses in biology. Courses in other departments may be substituted for minor requirements with the department’s permission.
Minor in Computational Methods; Concentrations in Environmental Studies and Neural and Behavioral Sciences
The Department of Biology participates with other departments in offering two concentrations within the major: environmental studies and neural and behavioral sciences. A minor in computational methods is available for students interested in computational methods and their applications to biology.
The College offers a certification program in secondary teacher education.
Animal Experimentation Policy
Students who object to participating directly in laboratory activities involving the use of animals are required to notify the faculty member of her or his objections at the beginning of the course. If alternative activities are available and deemed consistent with the pedagogical objectives of the course by the faculty member, then a student will be allowed to pursue alternative laboratory activities without penalty.
