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.	You study how to design and build structures and systems that work with geological materials and conditions — things like dams, tunnels, foundations, and mines. Unlike pure geology, you learn practical engineering design and problem-solving alongside earth science. The co-op requirement means you alternate between school and paid work terms at engineering firms, which is how you gain hands-on experience before graduating. This program suits people who want to combine science with engineering and need real-world workplace experience built into their degree.
