What it is	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.	Biological Sciences is the study of living organisms — their structure, function, genetics, ecology, and how they interact with their environment. At Brock, you can pursue this as a straight Bachelor of Science or combine it with teacher education through the BSc/BEd, which qualifies you to teach biology in Ontario high schools. The program includes a co-op option that integrates paid work terms with your studies, giving you practical experience in research labs, government agencies, or industry.	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.

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.
