When a Cell Talks, everyone listens!

This is a two part lesson focused on diffusion and cell communication.  In Part 1, students will use the classic starch iodine diffusion activity. This activity can be done in any life science class. It can be used as an introduction to diffusion or as a refresher activity for advanced students. The Part 2 activities introduces students to cellular communication. In these activities, students will determine if one cell has an effect on the cellular condition of other cells within close proximity. For both lessons, it will be important that students understand that these cell processes are occurring at the nanoscale.
