There is a whopping total of over one thousand flavors of ice cream in the world! This ranges from everything from chocolate, to pistachio, to even avocado! (Nautilator) Ice cream is a creamy dessert made mostly of milk, sugar, and various other flavorings. The first ice cream machine was made as far back as 1843 by Nancy Johnson.(Appalachian History) Even though ice cream has been around for generations, not everyone knows how to make ice cream or they don’t have enough time to make it. Many people think that it is much easier and convenient to buy ice cream from the store. But it can actually be cheaper to make ice cream homemade, you don’t even need an expensive machine to do it. You can make delicious ice cream with two bags, ice, salt or sugar, milk, and whatever flavoring you want. While salt and sugar melt ice, it freezes ice cream faster.
The first ice cream maker was patented in 1843 by Nancy Johnson. The maker was a very slow, hand crank design. It had a large bucket on the outside, a small bucket on the inside, and a crank to spin a paddle. When someone puts ice and rock salt in between the two buckets, and milk in the smaller bucket, then the ice would freeze a little bit of milk. After that, the paddle would mix the frozen milk into the center of the bucket, allowing a new layer to freeze.(Appalachian History) People still use this rock salt technique today, but isn’t salt supposed to melt ice? Why does it freeze ice cream faster?
The answer is, when you add salt to ice, the ice takes in surrounding heat to melt it. The heat is taken from the air around the ice and also taken from the ice cream right next to it. This makes the ice cream colder, allowing it to freeze faster.(Robertson, Bill) This technique is simple and easy to use. I think this experiment is relevant because if someone is making ice cream but needs to make it as fast as possible, this experiment could help them. This experiment could help them to determine how to make it fastest.
While salt and sugar melt ice, it freezes ice cream faster. It is hypothesised that if salt or sugar is added to ice, then salt will freeze ice cream will freeze faster. It would be great if a significant change is discovered between the results of the salt or sugar. This is because if there is not a significant change, then it won’t matter as much whether sugar or salt is used while making ice cream. But if there is a significant change, It will be much easier to see which one works better.
Salt and sugar freeze ice cream faster when added to ice, but it melts ice. The first ice cream machine was made in 1843 by Nancy Johnson. It used a technique using rock salt, this technique is still being used today.(Appalachian History) When salt or sugar is added to ice, the ice has to take in heat from the surrounding area, including the ice cream. This makes it freeze faster. This experiment tests the question: If salt or sugar is added to ice, which one will freeze ice cream fastest? It is hypothesized that if salt or sugar is added to ice, then salt will freeze ice cream fastest. Some real world applications are, if someone is making ice cream at home and needs to finish making it quickly, this experiment could help them. In conclusion, salt and sugar both melt ice, but they help freeze ice cream faster. In this experiment I will be finding which one freezes it faster.
