What it is	A Chemistry degree teaches you the theory and practice of how substances interact, break down, and combine. You'll study pure chemistry alongside molecular biology and biochemistry, giving you a broader foundation than a straight chemistry program. The co-op option lets you alternate between classroom semesters and paid work terms at companies, so you can test whether lab or industrial chemistry work suits you before graduating.	Environmental Geoscience is the study of Earth's physical systems — rocks, landforms, water, and climate — combined with how human activity affects and depends on the environment. It differs from pure geology because it emphasizes the interactions between natural processes and people, drawing on geography and environmental science alongside earth science. It suits students curious about how landscapes form and change, and interested in solving real-world problems like pollution, resource management, or climate impacts.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.
