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.

Titration Lab

Communication CC

I demonstrated my communication skills by working well with my partner in order to complete the lab. This took a long time to complete due to how accurate the measurements have to be to get the lightest shade of pink. My partner and I had assigned jobs of getting the right materials required. We then took turns testing out how to use the pipet and the burrette clamp. Since this lab requires more than one try, this allowed us to be more involved and fully engaged with the experiment. When measuring the HCl, one of us had to hold the pipet while the other will look from an eye level to get as accurate of the measurement as we can. The other one will slowly release the pressure so the the HCl will go down to the 100 ml line. After that, we communicated on how we execute the final part of the lab, which will determine whether we did it accurately. The substance cannot be a bright pink which is why me and my partner made a plan. One of us has to directly observe from an eye level while holding the erlenmeyer flask, while the other has to slowly and carefully twist the little knob so that not too much of the NaOH will be poured out. Overall, it was a very lengthy process but we managed to pull through.

I demonstrated my Communication skills through engaging in conversations with my friends and classmates every opportunity presented. We often discussed topics that is relevant in what were learning. I shared my own thoughts and opinions to the best of my ability with my classmates. Receiving feedbacks is interesting because I get to view a different perspective. There are times where we disagree on certain topics, but we often explain our reasonings that supports our cause in a friendly manner. This activities are helping me build relationships with my peers. I hope to be able to participate freely in class discussions more.
