Using Bubbles to Explore Membranes

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers. Learners also use the bubbles to form prokaryotic cells and eukaryotic cells. This inquiry type lab can be done as a group or cooperative learning experience. Materials listed are designed for a group of 30 learners.
