What it is	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.	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.	Physical Sciences is a broad first-year program where you study foundational chemistry, physics, mathematics, and biology before choosing a specialization in second year. The co-op option means you alternate between study and paid work terms at companies or research labs, giving you real experience in your field. This program suits students who are strong in math and science but not yet certain which specific physical science direction — from astronomy to polymer chemistry — they want to pursue.
