The first thing we did was to make the sodium acetate by mixing baking soda and vinegar and the liquid that we had left over is what we call sodium acetate. The next thing we did is heat it up for a long time ‐ How did your experiment turn out? Did it work? To what extent? My expierement turned out great. It worked even better that I had planned. The crystals in the end formed faster than I imagined they would and most of all I think it looked really cool. ‐ Describe how your experiment looked. Do you have any images or can you illustrate artifacts? Yes I have a video ive included it below and it shows the last part of the expirement when we crystalized it by touching it with antother crystal so that it would grow off of that one and then it would make many crystals. -Did you get desirable results? If yes, what did you think you did that contributed to desirable results? If not, then what do you think contributed to undesirable results? To get the results we got, I beleive that we followed the instructions precisley so our project outcome was what we expected, example: In the end when we touched the crystals to the liquid sodium acetate all the crystals started to form and expand making the entire thing turn solid right before our eyes. How do you think you performed in this activity? I think that I preformed pretty well during this activity but like always I could've been better. I left while the crystals were on the hot plate and came back when it was done but I shouldve stayed the whole time just in case something happened. Who did you work with? I worked with Alexander Uppenkamp How do you think your group performed? Our group preformed pretty well because we performed and finished the expirement successfully. Like everything else we could have done better. The first attempt we had problems and had to try again the next day. If you could do this again, what would you change to get better results? If we would do this again we would stay in the room while we had it on the heat plate so if anything happened we could fix it right away. If you were organizing a group for the next lab activity, who would you choose to work with again? We would work together again because we have a background together wich means we understand how eachother works and were able to strengthen eachothers weakness' Do you see any way to continue this experiment? Would you want to? We could heat it up again and repeat the same process over and over again as many times you want. I actually am thinking about doing this because it looks so awesome when you crystalize it What skills, techniques, or pieces or wisdom did you get from this activity? We learned how to crystalize sodium acetate from scratch (only using baking soda and vinegar) What do you think happened on a molecular level? (Looking beyond) Once you have your crystalized sodium acetate you melt it down so it no longer has its solid molecule structure but as soon as you touch the liquid with a small crystal they begin to grow off of it and continue to grow until its all a solid.
