What it is	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.	Environmental Engineering combines math, chemistry, physics, and biology to solve real-world problems like water treatment, air quality, and waste management. Unlike a pure science degree, you learn engineering design and practical problem-solving alongside the science fundamentals. The program includes mandatory co-op work terms, so you gain industry experience while studying. This suits students who want to apply science to environmental challenges and prefer hands-on learning alongside classroom work.	You study how Earth's physical systems — rocks, soil, water, and climate — interact with living things and human activity. This program combines geology, geography, and environmental science rather than focusing on just one. The co-op option lets you do paid work terms with employers in the environmental or resource sector alongside your coursework, giving you real experience before you graduate. This suits people interested in understanding environmental problems and possibly working in conservation, resource management, or environmental consulting.
