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 Bachelor of Science Honours is a four-year degree where you specialize in one science discipline — such as biology, chemistry, environmental studies, or nutrition — and take supporting courses in math and other sciences. The honours designation means you complete a research project or thesis in your final year. Many students choose the optional co-op stream, which alternates study terms with paid work placements in related fields, giving you practical experience alongside classroom learning. This program suits students who want depth in a single science and are interested in research, lab work, or professional roles in health, environment, or industry.	A Biology degree at Glendon lets you study how living things work, from cells and molecules to whole organisms and ecosystems. You'll take core biology courses and choose from specialized areas like genetics, microbiology, human biology, or biotechnology. The iBSc variant integrates bilingual (English–French) instruction throughout your degree, rather than offering biology taught only in English.	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.
