12. Lunar Ice Cream

The purpose of this activity is to give students a demonsrtation of freezing at different temperatures, to show how different compounds freeze at different temperatures (salt lowers the freezing temperature of the ice making it act "colder" ) and to introduce them to 3 common temperature scales -Farenheit, Celsius and Kelvin.

Students will place 1/4 C of ice cream mixture into a small baggie

Seal the baggie completely.

Place the sealed baggie into a large baggie

Add 1/4 C rock salt and ~2Cs crushed ice.

Seat the large baggie.

Agitate (shake) bag for ~ 10 minutes. When the mixture sealed in the inner small baggie is thickened, remove it from the large baggie, open and dig in
