What it is	Biological Sciences is the study of living organisms — their structure, function, genetics, ecology, and how they interact with their environment. At Brock, you can pursue this as a straight Bachelor of Science or combine it with teacher education through the BSc/BEd, which qualifies you to teach biology in Ontario high schools. The program includes a co-op option that integrates paid work terms with your studies, giving you practical experience in research labs, government agencies, or industry.	Honours Science is a broad science degree where you choose your major from fields like biology, chemistry, environmental science, computer science, or archaeology. Unlike a general science program, an honours degree requires you to specialize in one subject and complete more advanced courses in that area. It suits students who want a strong grounding in science but haven't yet decided on one specific career path, or who want deeper knowledge in a particular field.	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.	A Bachelor of Arts and Sciences lets you combine study in both humanities and natural sciences within one degree. Unlike most programs that require you to choose either arts or sciences, this one lets you take courses across both — for instance, pairing creative writing with chemistry, or anthropology with animal science. It suits people who are curious across multiple disciplines and want flexibility rather than specializing narrowly from the start.
