| This lab took a while and took a few tries to get right, but in the end our crystals came out great. They took so long because we always ran out of time and had to remelt the bismuth the next day. The day we finally got them done they came out great, Andrew even helped us get them to be a the really cool colors they are and helped maintain their color by putting propane on them immediately. Looking back: Our experiment went great, I am really happy how the color of the crystals turned out. Looking beyond: I don't have any idea on how the bismuth crystalized, but I do know that the more you moved it the more it vibrated with created smaller crystals. Also propane helps keep its color because oxygen makes the bismuth lose color whereas propane does the opposite and not only helps keep the cool colors but makes it that color. Looking inward: We got very good results and my whole group was happy with what we got. What I think contributed to our desirable results was the propane. Looking outward: For this lab I worked with Autrina and Evan, I hadn't worked with them before but I like working with them. I think we performed really well. Looking forward: There isn't anything I can think of to do differently to get better results. If i were organizing a group I would chose both of them we all work really well together. Takeaways: Since this lab took a while a takeaway for me is while waiting i should work on other ting, for example a worksheet. |
