Diffusion Race

Our sports medicine class participated in a diffusion race. We split up into teams and raced to see which team could diffuse glucose the quickest. My team put more sugar than water in the dialysis tube. Then, we submerged the dialysis tube into a beaker of deionized water. We tested the water with test strips every 5 minutes to check the levels of glucose in the deionized water.

My team and I made some errors during this race. First, our deionized water possibly could have had glucose in it already. Also, when creating our glucose mixture, the sugar clumped together preventing diffusion.
