In class on Thursday, we experimented with dry ice. We were trying to find out how to calculate the volume of a gas from a solid.
Looking Back: What happened?
Looking back, I would say that our experiment went pretty well. We tried to calculate the volume of a small piece of dry ice, and to do it we put it in a balloon. We tied it off, and by the time it melted it created a small balloon. My group also messed around a lot, and tried different things with the dry ice.
Looking Beyond: What do you think has happened? What’s the science?
Whilst experimenting, I was shocked to see how the balloon was expanding. I thought maybe the ice would freeze the balloon, but that didn't happen. I was confused on how the next steps we needed to take once the balloon expanded, in order to measure the volume. I understood that there was an equation, but we had failed to measure the piece of dry ice before hand. This made it difficult to make connections between the volume of a gas and a solid and the difference between the two.
Looking inward: Humans doing science
If I could do this experiment again, I would want to make sure we used a bigger piece of dry ice. The piece of ice we used was pretty small, so it didn't create the results we wanted. I would also want to make sure that we measure the piece before hand, so we can actually complete the experiment.
Looking outward: Collaboration and Impact
The group that I worked with was one that I worked with before. It was Monique, Sophie, Rebekah, and Fatuma. It was difficult because some of the members of my group weren't on task, and didn't know the point of the experiment. They were more interested in playing with the dry ice, and their own endeavors with it. This made me a little frustrated, because the point of the lab really interested me, and I genuinely wanted to understand the essential question. I think that if I had to work on a lab or project in Chemistry moving forward, I would want to change some of the people I worked with.
Looking Forward: What next?
Overall, I really enjoyed this lab and I learned a lot. It intrigued me how dry ice worked, and it was interesting to work with to say the least. I liked how many different things we were able to do with this lab, and all of the directions we could have taken it to. Down below are some pictures from the lab. Enjoy!
