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.	This program lets you study pure science in one of four areas: biology, chemistry, physics, or a mix of these subjects. You'll take foundational courses in your chosen field and build toward specialized upper-year courses. It suits students who want a strong grounding in how the natural world works, whether they're planning to go further in science or use that knowledge in other directions.	This program teaches you how to manage land, water, and communities in ways that balance environmental protection with human needs. You study soil and ecosystems alongside how people use and depend on natural resources, drawing from geography, agriculture, and related fields. It's a co-op program, so you alternate between classroom semesters and paid work terms with employers in conservation, government, or industry — giving you real experience before you graduate.
