Completion of Biology and Chemistry is recommended.	ENG4U MHF4U or MCV4U 2 from SBI4U, SCH4U, SPH4U, SES4U, or a second 4U Math Alternative Offers You will receive an offer of admission to only 1 program. Your highest listed choice is considered first when you indicate more than 1 Brock program on your application. If you are not eligible for your first choice, your subsequent choices will be considered in your indicated order of preference. In most cases: If you apply to only 1 Brock program but do not qualify, you will be considered for an alternative or related program. If you apply but are not admitted to a co-op program, you will automatically be considered for the regular, non-co-op program.	ENG4U MCV4U MHF4 Science prerequisites (SPH4U or SBI4U) for specific disciplines are also required. SCH4U is recommended for specific disciplines.

What it is	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	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.	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.
