What it is	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	Chemistry at Brock is the study of matter, reactions, and the properties of substances. You learn how atoms and molecules interact, and gain hands-on lab experience. The BSc/BEd option combines chemistry with teacher education so you can qualify to teach high school science. The co-op option lets you alternate semesters of study with paid work in chemistry-related jobs, giving you real workplace experience before you graduate. This suits students who want a practical understanding of how chemistry works in industry or education.	A Bachelor of Science (General) lets you study science broadly across biology, chemistry, environmental science, and related fields, choosing your own mix of courses rather than specializing deeply in one area. Unlike an honours program, it gives you flexibility to explore multiple sciences without committing to a single major or meeting the tighter requirements of a specialized stream. This suits students who are curious about science in general but aren't yet sure which direction appeals to them most.
