Abstract:
Transport of molecules across the cell plasma membrane can be a difficult concept for introductory biology students to understand and visualize. Role-playing activities provide a simple, cost-effective method for enhancing student understanding of various challenging biological concepts. This cell membrane role-playing activity was designed to teach introductory biology students how small nonpolar and polar molecules cross the cell membrane as well as the importance of diffusion, osmosis, and tonicity.

FIGURE 1
Diagram showing how the students are arranged in the classroom during Part 2 of the activity. The grey circles represent two students acting as channel proteins, the white circles represent students acting as water molecules. In this scenario, there are more water molecules outside the cell than inside the cell (the cell is in a hypotonic solution) so water molecules will move into the cell though the channel proteins until the number of water molecules is equal on both sides of the cell membrane (represented by the dotted line).
