(Because I am slow on getting some things posted, yet again, I am combining the Middle School Monday post with my Blogging Through the Alphabet. Enjoy!)
Working through the Apologia Astronomy curriculum has given us a number of fun opportunities. One of the labs that was suggested was making ice cream. We could not ignore that experiment/lab!
The purpose of the experiment was to see the how chemicals (in this case – salt) could create a cooling effect. This was in relation to the gas giant planets, specifically Neptune, that are cold not only because of the distance from the sun but also because of the chemicals in the atmosphere.
The experiment was fun and tasty but there are a couple of things we would recommend in regards to it:
– Do it outside if at all possible; this is messy and salt water on some floors is not good
– Perhaps use a small plastic jar or container that will hold the liquid and put it in the large zipper bag with ice and salt. Trying to get ice cream out of a zipper bag that has salt all over it is difficult and salty ice cream is not my favorite.
All in all – a super easy and very tasty way to see the effects of chemicals mixing to create a lower freezing temperature.
