Looking Back: What Happened? I think this experiment worked out really well, we got our desired results which was good ice cream, and we were able to learn about the science behind it as well. I've only made ice cream once and that was in fifth grade in a bag, so I wasn't sure how it was going to turn out and I was pleasantly surprised. Since none of us have ever made ice cream with an actual machine I thought we would struggle with how to use the machine, but we figured it out by making sure we looked at all of the pieces a day before. Looking Beyond: What's the Science? Even though the reason why we wanted to do this experiment was to make some homemade ice cream, I really enjoyed learning about the science and why ice cream turns out the way it does. Whenever I learn about the science in food it makes me appreciate the process more, and so now whenever I eat ice cream I think about how all of the ingredients play a key role in how it turns out. The milk in the ice cream adds fat, and richness it also balances the base mix, improves the density, smooths out the texture and overall give it a better taste. The sugars or syrups that are added to ice cream not only sweeten the taste but they also help refine the texture and body. The sweeteners also drop the freezing point of the mixture making it so the ice cream doesn't become one hard brick, they build the stability of the ice cream. The water content in the mix is the reason why the ice in ice cream is apart of the name, it starts to freeze making the ice cream solid and making its body. Looking Inward: Did you get desirable results? Yes I feel like we got desirable results, because we made really good ice cream from scratch. I think the reason why we got the results we wanted was because we all worked together as a team. I helped us get these results by bringing in some of the materials that were needed, I also suggested we take a look at the machine and the pieces so we wouldn't have to worry about that the day of. Looking Outward: Collaboration and Impact For this lab I worked with Savreen and Morgan and I think that we worked really well together, since we're all friends we know each other's strengths and weaknesses. That is one of the positives of working with your friends, you know that they are actually going to get work done instead of goofing off the whole time, and if they get off task you're not afraid to tell them something. One thing that we could've done differently is have the materials ready a day before because, the day of our lab we had to run out to Vons to get ingredients which was a little stressful. Looking Forward: What's Next? I think if I were to do this project again, I would want to have all of the materials the day before or at least the morning of because when we got to Andrew's class we had none of the ingredients we needed. That was kind of stressful, especially when we were at Vons and we weren't sure if they had any whipping cream in stock which is a very important component in ice cream. I feel like I work well with Savreen and Morgan, we all contributed in some way and it was fun doing this project with them. There aren't many ways we can continue this experiment, one way we can is by making ice cream in a bag, and comparing the process and the results. Takeaway: Summary Before we even started gathering the materials we needed or making a plan we looked up a little bit about the science behind ice cream, so we knew what was actually going on, on a molecular level. After we did that we started the actual process of making the ice cream, we mixed all of the liquid ingredients together, then we mixed in the sugar until it dissolved. Since we had an ice cream maker available to us we set that up and then poured our mixture into the opening, before we could add in the cookies we had to let the mix thicken up a bit. After it had thickened to the right consistency which is when the ice cream should be almost done we added the cookies and let them mix in. Once everything was done we ate our final product and even shared it with our classmates.
