The History of Ice Cream

Apparently, the Roman emperor Nero invented the first ice cream, after sending runners to the peaks of mountains to gather snow for it. After that, in the year 1846 the hand-churned ice cream maker was invented by Nancy Johnson, and the notion of making ice cream quickly spread. In 1904 ice cream's usual companion, the ice cream cone, was invented at St. Louis World Exposition, when an ice cream vendor ran out of dishes, and served ice cream in rolled waffles.

We will be making ice cream as a demonstration of an endothermic reaction. We will be mixing ice with salt to cool the ice cream, which will show how the ice melts better with salt in it.

We began by adding all the ingredients into a small ziplock bag.


½C Milk :)

½C Whipping Cream

¼ Tsp. Vanilla Extract

¼C Sugar

Then, we mixed salt and ice in a larger ziplock bag.



After that, we put the smaller bag inside the larger one and squished them until the ice cream ingredients solidified.


Finally, once the ice cream was finished, we served it up and ate it. :)


Don't forget to wash off the salt!

Why did we add salt to the ice?We added salt to the ice for the same reason salt is placed on roads in the winter; because it lowers the freezing temperature of water. Or, if the temperature stays the same, it basically melts the ice. This allows us to have the mixture below freezing point, and still in a liquid form, making the ice cream freeze more quickly.When we put the smaller bag into the larger one, the ice cream hardened, and the ice melted. Why?When the smaller bag was placed in the larger one, and we squished them together, an endothermic reaction occurred. Endo means within, and Thermic means heat, so endothermic means within heat, or absorbing heat. The salt and ice absorbed the heat from the shaking of the bag, and the ice cream inside. This froze the ice cream, and gave us our final product. Finally, we found the temperature of the melted ice to be -15 degrees Celsius, despite the freezing temperature of water is 0 degrees Celsius. This proves that the salt kept the water from freezing, and helped the ice cream freeze instead.
