My Essay

Core Competencies Reflections

Evidence that I can acquire information about complex and specialized topics from various sources, synthesize it, and present it with thoughtful analysis can be found in my connections made from examples in the novel to the title, with different levels of depth.

I show that I value feedback from others in my group by asking for their opinions or thoughts on my work and adjusting my writing based on constructive feedback given.

I compile and synthesize information to draw reasoned conclusions, such as when I researched through the novel for examples of Holden’s connection to the title through knowledge of his personality and feelings to connect the ideas.

When I need to work collaboratively with people I don’t know well, I… am working towards improving being able to work well with people I don’t know by learning to be able to take the first step and initiate discussion about the topic.

Diffusion Lab Self Reflection

Critical Thinking

Initial
After 24 hours

Critical thinking was very important for this lab in order to figure out which molecules diffused through the membrane, which way. Part A of the lab contained the molecules water and IKI in the beaker creating a yellow colour, with starch inside of dialysis tubing submerged in the water with a translucent milky white colour. After 24 hours the starch inside the tubing had turned deep blue and the water in the beaker had turned colourless. We used our critical thinking to identify that it appears the IKI and some water had diffused through the membrane and into the tubing. The evidence that the IKI had diffused was the change in colour, and evidence of the water diffusing was the increase in weight. For Part B the experiment started with glucose inside dialysis tubing submerged in a beaker of water and a glucose test was conducted in the water with the result of 0. After 24 hours the tubing had expanded and a glucose test was conducted again with the results of 300. This glucose test makes it appear that the glucose had diffused out of the tubing and a change in the weight of the tube makes it seem that water had diffused into the tubing. Without using critical thinking we would not be able to have identify what made it possible for the glucose, IKI, and water to move in and out of the dialysis tubing.

Communication

Communication was essential for this lab because we worked in partners to complete it. My partner and I completed Part A of the experiment and needed to be able to work together to efficiently put together our beaker and dialysis tubing. My partner and I split up to obtain the materials needed and then came back together to help each other assemble the tubing and beaker. To fill the dialysis tubing we decided one of us would hold the tube and the other would use the pipette to fill the tubing with ten millimeters of starch. After the tubing was filled, my partner twisted the tubing and I tied the string to secure the starch inside. Finally when one of us was finding a clip to hold the tubing, I filled our beaker with distilled water. None of this could have been possible if we didn’t work well together and communicate well enough to divide up our tasks and efficiently complete the lab.
