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.	A four-year Bachelor of Science in Biology teaches you how living organisms work, from cells to ecosystems, with a focus on environmental systems and conservation. You'll study ecology, genetics, physiology, and how species interact with their surroundings, combining lab work with field study. This program suits students who want a broad foundation in biology and are interested in environmental issues, rather than pursuing a specialized professional path like medicine or engineering.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	This program combines science study with teacher education, so you earn qualifications to teach science in secondary school while completing your degree. Unlike a regular science degree followed by teacher training, you work toward both goals at the same time, with coursework in science disciplines alongside education theory and practice teaching. It suits students who know they want to teach and want to study science deeply rather than broadly.
