Welcome to Biology 20, an exciting and rigorous exploration of the processes that sustain life on Earth. In this course, students deepen their understanding of biological systems by examining how organisms obtain energy, how they maintain internal balance, and how they interact with their environment.
Biology 20 emphasizes energy flow, human physiology, and ecosystem dynamics, helping students connect molecular processes to global patterns. Through laboratory investigations, data analysis, modeling, and scientific inquiry, learners develop strong analytical skills and a deeper appreciation for the complexity of living systems.
Students will explore:
How cells capture and use energy
How human organ systems work together to maintain homeostasis
How photosynthesis and respiration power life
How ecosystems function and respond to change
How populations grow, decline, and interact
Biology 20 prepares learners for Biology 30, post‑secondary science pathways, and real‑world applications in health, environmental science, biotechnology, and research.
