Looking Back: What Happened? For this lab Savreen, Elyse and I made fake snow, and it was a lot easier than I expected it to be. The fake snow turned out how we wanted it to for the most part, we got a lot of the fluff in with our sodium polyacrylate which made the fake snow a weird consistency. Looking Beyond: What's the Science? Making fake snow is very simple the sodium polyacrylate does all of the work, it is a very absorbent polymer, so when the water was added it soaked it all up and that process is called osmosis. What's happening more specifically is the water molecules are making the sodium polyacrylate stretch to a large size. When the molecules pass through the polyacryclate which is a polymer molecule it makes it inflate almost. When you add salt to the fake snow it will eventually turn back into water with only little bit of salt and polyacrylate in it. Looking Inward: Did you get desirable results? I think the results we got were okay, we knew where to ind the sodium polyacrylate but while we were looking for it we somehow mixed it up with the fluff in the diaper. This made our fake snow turn out not as well as we hoped, the fluff was somewhat absorbent so you could see the difference from that and the ppolyacryalte. I think I performed well during this lab, I contributed a lot when it came to typing the proposal because I was very eager to get this lab done. Also while making the actual fake snow, I helped with mixing our ingredients together and documenting the process. Looking Outward: Collaboration and Impact For this lab I worked with Savreen and Elyse, and I think we worked really well together. We were all partners in our other class so it was really easy to work together because we knew our own skills and each others as well. I contributed a lot to the typing out the proposal, and I also made sure I knew a lot about what we were doing before hand, because I didn't want to get confused during the making of the fake snow. Looking Forward: What Next? If I could do this lab again I would make sure I know how to separate the fluff from the sodium polyacrylate so we can actually make fake snow that works well. I also wouldn't want to rush as much, since there were a lot of people working inside we decided to work outside, and it started raining while we were out there which made us rush. I would for sure work with Savreen and Elyse again, for the last section I want to try working with more people, I think I've started doing that in the last two sections which I want to keep on doing. I think there are a few ways to continue this experiment, the first one being doing it again to get better results, the second one being making hair gel out of sodium polyacrylate. Takeaway: Summary This was a very easy and simple lab, all we had to do was get a diaper and take the sodium polyacrylate out of it and put it in a beaker, then in a separate bowl of water we had water. Slowly we started putting drops of water into the beaker watching the water disappear. Then we poured in the rest of water into the beaker and it was soon all gone, it was really cool to play with and make.
