What it is	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.	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.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.
