Biology allows students to study life from the molecular all the way up to the ecological level. Class begins with a unit on evolution, giving students a conceptual framework to understand the origins of all the phenomena we go on to study. Other fall units include biochemistry and macromolecules, diffusion and osmosis, and energy and matter in living systems including photosynthesis and cellular respiration. In the spring, students study cell division, genetics, and ecology. Throughout the year, students continually put their learning in context to reflect on how it can give them a deeper understanding of the real world and their role in it.
