| For the second part of the lab we analyzed solids and gases using dry ice. We dropped a small piece of dry ice into our beaker of water and observed the difference in the amount of solid comparing to gas. When the dry ice hit the water it immediately started to bubble and when the bubbles popped the released gas. After observing what it was like in water we put a small piece of dry ice into a balloon. Within a few minutes the gas made the balloon blow up. I think it took longer for the gas to release in the balloon than it being in water because there was no water. Andrew also showed us how dry ice under pressure turned into a liquid and when released it shot out as a gas. Inward: In this activity I think I performed well but I would've liked to focus more on the ratio of solid to gas. I felt my group would sometimes get distracted and forget to observe but overall I think we did a good job. Outward: In this activity I think I performed well but I would've liked to focus more on the ratio of solid to gas. I felt my group would sometimes get distracted and forget to observe but overall I think we did a good job. Backward: I think this lab was successful since the most challenging part was putting the dry ice in the balloon and fortunately we were able to get it in. Forward: If I could do this again i would have taken more notes while observing the dry ice in both the water and balloon. Beyond: I think the water was melting the dry ice very quickly and that's why it bubbled immediately, whereas when it was in the balloon it took longer to melt because it was just the air that was melting it. Takeaways: A takeaway for me was to choose your partners wisely and not to just choose your friend because it very easy to get distracted. |
