Cell Membrane Lab

Collaborating

I worked with others to achieve our goal. My lab partner and I had to help each other to tie the ends of the tubes. We needed to collaborate and make sure we got the correct amount of starch in the tube. We also worked together to ensure there were no air bubbles and tied it differently a couple times to get it as close as possible. I made sure we were clear on the common purpose of the lab by talking through everything, and explaining anything that wasn’t understood. For example we were a little confused about when to add in the IKI but after talking it out and asking questions we understood what to do.

Critical Thinking

I analyzed evidence to make judgements. After 24 hours of diffusion the starch in the dialysis tube turned very blue. I used this evidence to make a judgement that the IKI entered into the tube and changed the colour of the starch. Further evidence is that the water in the beaker was no longer yellow meaning the IKI must have diffused somewhere else. Also, I remained open-minded as I explored different options because I had no idea if my hypothesis would be supported or not. But I was able to make a judgement after the lab that supported my hypothesis.
