What it is	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.	A Biology degree at Glendon lets you study how living things work, from cells and molecules to whole organisms and ecosystems. You'll take core biology courses and choose from specialized areas like genetics, microbiology, human biology, or biotechnology. The iBSc variant integrates bilingual (English–French) instruction throughout your degree, rather than offering biology taught only in English.	You study living organisms and how they work at every level, from whole animals and plants down to cells, genes, and molecules. This is a research-focused program where you can choose to include paid work terms alongside your courses, giving you real lab or field experience in biology-related workplaces. It suits students who want a solid foundation in biology and enjoy the idea of testing what they learn in actual research or applied settings.
