Faculty of Science (SC) – Undergraduate Degree and Certificate Programs

Students may choose to major in a specific subject when they enter the University or they may wait until they have completed up to 24 credits. At this point, students must choose a major, but subsequent changes are possible. In selecting courses, students who are undecided should try to take introductory courses in a number of potential major subjects. This will allow them to proceed in their subject of choice without the possibility of a delay. Some departments will not permit undecided majors to enrol in their courses.

Joint Study Programs

Intra-Faculty Double Major and Major/Minor Programs

Most subject areas within the Faculty of Science offer Honours Double Major and Honours Major Minor programs jointly with another subject area in the Faculty, allowing students to concentrate on two fields of interest. Such programs are open to students who have completed 24 credits in an Honours program and who satisfy the Faculty of Science academic standards to proceed in Honours. All Honours programs require a minimum of 120 credits which can normally be completed in four years of full-time study. For a list of possible subject combinations, refer to the sections above. Some combinations may require more than 120 credits.

Inter-Faculty Honours Double Major and Major/Minor Programs

The Faculty of Science jointly offers Honours Double Major programs and Honours Major Minor programs with other Faculties at the University, allowing students to combine diverse areas of interest. Such programs are open to students who have completed 24 credits in an Honours program and who satisfy the Faculty of Science academic standards to proceed in Honours. All Honours programs require a minimum of 120 credits which can normally be completed in four years of full-time study. Combined program require careful planning and may take longer than four years, and/or move than 120 credits to complete.

A program involving a first major in the other Faculty and a major or minor in the Faculty of Science lead to an Honours BA, BES, BFA or BSc degree in the other Faculty.

For a list of possible subject combinations, refer to the sections above. For details of the major or minor requirements for each program in the Faculty of Science, refer to the Faculty of Science Programs of Study section. For details of the major or minor requirements in the other Faculty, refer to the Programs of Study section of the appropriate Faculty.

Science and Education

A student wishing to obtain the professional certification required to teach in Ontario schools may take both teacher training and an undergraduate academic program concurrently. This does not shorten the time required to gain the qualification but provides a better chance for the student to relate theory and practice and to have more opportunity to gain practical experience than is possible in a one-year program.

A student in the Faculty of Science who is presently enrolled in first year (at least 24 credits) or has a minimum of 36 credits remaining in the BSc, Honours BSc, BA or Honours BA with an overall standing of at least 5.00 (C+) may apply to coregister in the Faculty of Education. A coregistered student normally takes one and a half or two full courses in the Faculty of Education in an academic year concurrent with courses for the BSc, Honours BSc, BA or Honours BA. The specific study program of each student is subject to the approval of both Faculties.

Upon successful completion of the course requirements for the degree in the Faculty of Science, and of the required education courses, a coregistered student is awarded a BSc, Honours BSc, BA or Honours BA and a BEd.

Certificate Programs

There are numerous certificate programs offered by other Faculties in various subject areas, allowing recognition of a specialised area of study. Certificate programs are open to all undergraduate students, subject to student eligibility and course availability. The following certificates, offered by departments in other Faculties, may be of interest to students taking programs in the Faculty of Science.

Certificate in Geographic Information Systems (GIS) and Remote Sensing

This certificate is offered jointly by the Department of Earth and Space Science and Engineering of the Lassonde School of Engineering, the Department of Geography of the Faculty of Liberal Arts and Professional Studies and the Faculty of Environmental Studies.

The certificate program includes three streams, one offered through each of the three units above. Honours BSc or BSc candidates majoring in environmental science or geography may be particularly interested in this certificate.

For additional information, consult the three units mentioned above.

Certificate in Meteorology

This certificate is offered by the Department of Earth and Space Science and Engineering, Lassonde School of Engineering. The program is open to any student who satisfies the program admission requirements. Entrance to the program requires the candidate to have successfully completed at least 54 approved credits (nine approved full courses) in the areas of physical science and mathematics.

For additional information, consult the Department of Earth and Space Science and Engineering.
