The Major in Biological Sciences
The interdisciplinary major in biological sciences, offered jointly by the Biology and Botany Departments, consists of courses in biology, chemistry, mathematics, and computer science. Students may choose the general track or may customize the major by selecting a concentration either in ecology or in cellular and molecular biology.
The major consists of fifteen courses: six core courses, two quantitative and physical science courses, one capstone course, one semester of the Biology/Botany Seminar Series, and five electives dependent on the track or concentration. The Advanced Placement examination in biology may not be counted toward the major.
All biological sciences majors must take the following courses:
Biology 105, 106, 207, and 208; Chemistry 103 and 104 (or 107 and 204).
Quantitative and physical science courses
All majors must take two of the following courses:
Mathematics 107, 111, 112, 113, 206, 207, 208, 212; Psychology 201; Computer Science 110, 212; Physics 107, 108, 109, 110; Chemistry 223, 224.
For students concentrating in ecology, one of these courses must be in statistics (Mathematics 107, 206, 207, 208, or Psychology 201). Students considering graduate school or a career in the health professions are strongly encouraged to take organic chemistry, physics, and calculus or statistics, and so should complete more than the minimum number of required courses.
All majors must take one of the following courses during their senior year:
Biology 493, 494; Botany 493, 494. Students may, with approval of the appropriate department, select an Individual Study (391, 392) or Honors Study (497-498) in either biology or botany.
Biology/Botany Seminar Series
All majors must take either 293 or 294.
All majors must take five electives, chosen to satisfy the requirements of one of the following tracks or concentrations. Electives may not duplicate any courses already selected.
1. General Track
Students may take any five courses chosen from additional offerings in biology or botany, or in organic chemistry (Chemistry 223, 224) or biochemistry (Chemistry 303). Science-based Environmental Studies courses may be selected with approval of the major adviser. At least three of these courses must be at the 200 level or higher, with at least one at the 300 or 400 level; at least two of the courses must include a laboratory component.

Learning Goals in the Biological Sciences Major
One of the major learning goals that the Department of Biology Faculty share is to instill in students the thrill of discovery and the nurturing of curiosity. Toward these goals we aim to provide students with opportunities to make their own discoveries through independent research conducted at all levels of our curriculum. From this work we expect our students to become proficient in experimental design, hypothesis development, data analysis and critical reading of primary and secondary literature. Our overall objective for our students is to have them come to know biology as a way of understanding, rather than a particular body of information. As we help students to learn current knowledge, we strive for that knowledge to persist beyond the course in which it was acquired.
The Learning Goals of the Faculty of the Biology Department are:
- Instill in students the excitement of discovery and nurture creativity.
- Produce and critique logical arguments through generation and testing of hypotheses, analysis of data and evaluation of results.
- Acquire a fundamental knowledge of biological principles at all levels of biological organization from cells to ecosystems.
- Develop the ability to find and synthesize current scientific knowledge.
- Communicate ideas and arguments in both oral and written form.
- Work effectively as individuals and in groups.
- Understand the ethical responsibilities of scientists and societal understanding of science.
SKILL BUILDING AND APPLICATIONS
Our department believes that educating students in the Biological Sciences requires a number of skills including the ability to identify and understand pertinent published research, design and perform appropriate methods, critically analyze results, and present information clearly to a community of peers. We believe it is important that our students are able to apply their knowledge to the world they inhabit as citizens in a global society.
