At CHS, Mrs. Fischer’s AP Bio students conducted a bubble lab to explore the properties of cell membranes. In this video clip, students are modeling the process of binary fission in bacterial cells. When bacterial cells divide, a thin ring of proteins located at the cell’s midpoint contracts, effectively cleaving the cell in two. The lab also shows how membranes are fluid and flexible, how they can self-repair, how membrane-bound organelles can form inside cells, and how proteins can drift across lipid layers – all with a special bubble mixture of soap, water, and corn syrup.
