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.	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 & 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.
