Bring passive cell transport to life in this student laboratory kit. Students create an artificial cell using dialysis tubing and simulated cellular fluid containing a special dye and glucose. The diffusion of dye through the membrane can be directly observed, but what about the water and glucose? Mass and volume measurements prove that osmosis takes place, while glucose test strips confirm that the unseen glucose molecules also diffuse though the pores in the artificial cell membrane. Kit includes reproducible student handouts, detailed background information, complete teacher notes with sample data and answers to all questions, and all chemicals and consumable supplies needed to perform the lab. Complete for 30 students working in pairs.
