Chemistry is the study of molecules and as such is central to both the physical and biological sciences. Chemists have played significant roles in resolving many scientific problems ranging from decoding the DNA molecule to the discovery of semiconductors. Chemistry courses offer students the opportunity to master the chemical concepts necessary for an understanding of much of the natural sciences. These courses encourage students to think independently, to approach problems and tasks creatively and skillfully, and to test hypotheses critically. Laboratory experience is integral to most chemistry courses. Experimental design, modern laboratory techniques, and data analysis are emphasized. Courses, internships, and research are all part of the chemistry program, and academic credit can be earned for each.

Major Program. The chemistry major encourages students to achieve a sound understanding of the fundamental concepts of molecular science, to employ scientific approaches to tasks and problems, and to prepare for careers in industry and technology, for professional health science schools, for teaching science, and for graduate study in chemistry. Wesleyan chemistry majors have enjoyed success in all these and other career options.

Students are first exposed to a survey of modern chemistry in a two-course sequence. This background provides the basis for more specialized studies in analytical, organic, inorganic, and physical chemistry, which together form the core of the major. Upon completion of the chemistry major, students will be prepared to pursue graduate studies in chemistry or to enter professions that required a strong and diverse background in the field or a general degree in science. Further, they will be well suited to continue their education in medicine, pharmacy, dental, veterinary, or allied health fields.

Forensic chemistry, biochemistry, and special topics in chemistry are electives which serve to provide further breadth and depth to the student's knowledge of chemistry, as does a required course in research methods. To ensure breadth in ancillary disciplines which are important to the study of chemistry as a central science, students also take courses in physics and mathematics. Near the completion of their studies, students enroll in our research-intensive capstone course designed to develop insights into the interconnections that exist between the subdisciplines of chemistry, and between chemistry and other natural sciences. Department faculty can be contacted to help with initial course selection and the development of a long-range plan for course sequencing. Aspirants for medical, pharmacy, dental, allied health, and veterinary schools must satisfy the specific entry requirements for those schools.

Major Coursework Requirements: Chemistry

The chemistry major curriculum is designed to meet the needs of students who plan to graduate school in chemistry or to enter professions that require a strong background in chemistry. Further, this course of study is suitable for students who plan to continue their education in areas requiring a strong background in science, such as medicine, pharmacy, or allied health fields.

Requirements: A minimum of 55 semester hours. These include the chemistry core courses (41 semester hours) of CHM 101, CHM 102, CHM 221, CHM 222, CHM 240, CHM 320, CHM 361, CHM 412, and three courses from the following: CHM 318, CHM 325, CHM 362, and CHM 396. Other required science and mathematics courses (14 semester hours) include PHY 121 and 122 (or PHY 115 and 116), and MAT 205, 206. Additionally, MAT 207 is recommended.

Five student learning outcomes have been identified for the required courses in the Chemistry major:

Professional Development: Throughout her Wesleyan education each student is given opportunities to explore professional and career choices, and to develop and demonstrate the knowledge and skills essential for professional success. Each student will complete a PDE 400 Professional Development Experience and submit a PDE 401 Professional ePortfolio prior to graduation. The Professional Development requirement in Chemistry is met through CHM 452 Field Study. Students are encouraged to pursue internship and research opportunities with faculty members and with local laboratories.

Chemistry Minor. The minor in chemistry encourages students to acquire a solid knowledge base of the fundamental concepts of chemistry, an understanding of more specialized areas within the discipline, and the ability to employ the process of scientific inquiry within the laboratory setting.

Minor in Chemistry Requirements: The chemistry minor consists of a minimum of seven courses within the discipline. These courses will include a core curriculum (25 hours minimum): CHM 101 and 102, 221 and 222 (or 361 and 362), 240 and two 300-400 level chemistry electives.

Resources for Non-Majors. All Wesleyan students are welcome to include some chemistry courses in their curricula of study. CHM 101 may be used to satisfy the general education requirements category. In addition, CHM 101 and 102 provide the necessary background for advancement to additional coursework within the chemistry program. Non-majors can elect to take additional coursework in chemistry within the prerequisite structure.

Undergraduate Research Opportunities. Research is a highly desirable component of the curriculum for chemistry majors. Many upper-level chemistry courses have research components. Independent research experience is strongly encouraged as a prelude to a career in chemistry or to post-graduate study. Chemistry faculty welcome the opportunity to support and direct the research efforts of students enrolled in CHM 451, 452, and 499, and to have students participate as research assistants in ongoing faculty research programs. Students in this program receive academic credit and usually do not require additional semesters in order to complete degree requirements. Students are also welcome to participate in other internships through the College's internship program.
