In this lab, the core competency that I demonstrated was communication with my lab partner. In this lab, we had to communicate efficiently for the lab to run smoothly and for all tasks to be completed. We gave each other certain roles or tasks in the group so that we could get through the procedure effectively. For example, one person would be in charge of measuring one substance while the other person would follow along by adding the second substance. Then for our next step, one person would be in charge of observing the change in the precipitation and temperature while the second person would record the data. We split roles like this throughout the entire lab and had to communicate when we switched tasks so that there wouldn’t be any misunderstanding. This was important because, with the limited amount of time and large tasks, we had to strategically set out roles. Also throughout the lab, we were able to communicate with each other what we thought was going on and share our opinions while working together and coming to a conclusion. In this lab, I was able to work on my communication skills and collaborate with my partner to successfully finish lab 19C.
