Make Homemade Ice Cream Using Physics

Description:

A webinar for grades 3 and up to make ice cream without an ice cream machine. Parents are welcome to join in and help, or even make their own batch. We will use the second law of thermodynamics (that heat flows naturally from higher temperature objects to lower temperature objects) to cool down our ice cream mix. By the end of the webinar, your ice cream will be ready to eat. You will need to get the ingredients listed below to prepare for the webinar.

Ingredients:

Ice, sugar, salt, milk, vanilla extract, 1 small ziplock bag (no smaller than the regular 6 ½ in * 5 ⅞ in sandwich bag), 1 big ziplock bag (approximate 10 9/16 in * 10 ¾ in), a teaspoon, a tablespoon, a measuring cup.

Remember, you can also get strawberries, chocolate syrup, or anything else that you would like to put into your ice cream.

Quantity of Ingredients:

3 cups of ice

2 tablespoons of sugar (powdered sugar works best)

1 cup of milk (or half and half)

1 small ziplock bag (no smaller than the regular 6 ½ in * 5 ⅞ in sandwich bag)

1 big ziplock bag

½ teaspoon of pure vanilla (for flavour)

⅓ cup of salt
