During our Chemistry 11 titration lab, I demonstrated critical and reflective thinking by carefully analyzing the results and identifying sources of error. My artifact is the lab report I completed after the experiment, where I calculated the concentration of an unknown NaOH solution using a standard HCl solution. I showed thinking skills by applying the molarity formula correctly, double-checking my data, and making sure my work was accurate. After the experiment, I reflected on how I could improve next time—for example, I realized that a small delay in noticing the endpoint could affect the volume reading, so I wrote down that I would use a more consistent swirling technique and observe more closely in the future. This shows how I used scientific thinking to solve a problem and then thought about ways to do better. I also worked with a partner and we shared ideas and responsibilities, which helped me become more aware of how teamwork and communication play a role in learning. Overall, this lab helped me grow as a learner by combining thinking, reflecting, and collaborating.
