Making ice cream is great way to enjoy a tasty treat, plus it involves several chemistry and other science concepts. Here's a collection of easy and fun science ice cream recipes, including classic liquid nitrogen ice cream, homemade Dippin' Dots, dry ice ice cream and more.
Homemade Dippin' Dots Ice CreamDippin' Dots Ice Cream is made by cryogenically freezing ice cream into little balls. RadioActive, public domain
Dippin' Dots are another type of flash-frozen ice cream. If you have liquid nitrogen, this is another fun and easy ice cream project to try.

project. The nitrogen instantly chills the ice cream, but is not an actual ingredient. It boils away harmlessly into the air, leaving you with instant ice cream.
Instant SorbetYou can prepare sorbet instantly by chilling the fruit juice in a bag containing ice, salt and water. Renee Comet, National Cancer Institute
You can make a flavorful, fruity sorbet just as easily as you can make ice cream. The rate of cooling impacts the consistency of the sorbet, so you can explore crystallization as well as freezing point depression.

If you have snow, you can use it to make ice cream! Salt can be added to snow to use it to chill the ice cream via freezing point depression or you can use the snow as an ingredient in the recipe.

it carbonates the ice cream. This produces an interesting flavor and texture that you won't get any other way.

You can use any ice cream recipe as a basis for scientific exploration, plus you don't even need an ice cream maker or even a freezer! Freezing point depression cold enough to freeze ice cream is the result of combining salt and ice in nothing more complicated than a plastic bag.
