Cell Membrane Diffusion Lab

Starch

Glucose

Communication

In a group of 4, there would be 2 pairs; one pair will be working on the starch diffusion and the other pair on glucose diffusion. My partner and I discussed what we needed to do step by step in order to avoid as much error as possible. From filling up the dialysis tube with an accurately measured starch, to tying up both ends as securely as possible, everything has to be done well to have a successful outcome. There were times during this procedure where we got stuck on a problem, we would read the instructions amongst ourselves and to each other and try our best to understand it. Collaboration is also important because we need to share our observations, both qualitative and quantitative amongst the group during the lab and after the 24 hour period.

Thinking

In order to complete this lab, creative thinking is an important aspect to have. The dialysis tubes were either sticky or slippery (depending on whether it was glucose or starch) and was a challenge to be able to tie the string on both ends of each of the tubes. My partner and I had to be creative to be able to secure the starch inside the dialysis tube with no air bubbles and tied multiple knots to ensure that the starch wasn’t leaking. Critical thinking is also important to analyze procedures and understanding it throughout.
