What it is	You study how Earth's systems work — its atmosphere, weather, climate, oceans, geology, and space — using physics, chemistry, and math. This program lets you do paid work terms with employers alongside your courses, giving you real experience in research labs or environmental organizations. It suits people curious about how the planet functions and wanting to test their skills in the field before deciding on a career.	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.	An Honours Science degree lets you study a science subject deeply — biology, chemistry, physics, computer science, or another physical science — and choose your own focus within it. Unlike a general science program, an Honours degree requires a concentrated major and typically includes a research or capstone component. The co-op option means you alternate between school terms and paid work placements in science-related jobs, which suits people who want real workplace experience alongside their degree.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
