What it is	Biology is the study of living organisms, from cells and genes to plants and animals. This program lets you choose to add paid work terms in research labs or related industries alongside your courses, giving you real experience before you graduate. It suits students who want hands-on learning and a chance to explore career options while earning money.	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.	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	Physical & Environmental Sciences is a degree where you study the natural world through disciplines like physics, chemistry, geology, astronomy, and environmental science. You choose which areas to focus on based on your interests. The co-op option lets you alternate study with paid work terms in science-related workplaces, giving you real experience alongside your classes. This program suits students who want to understand how Earth and space work and prefer hands-on learning combined with classroom study.
