One of the things I love about the Easy Peasy curriculum is the fun science experiments.  If you haven’t noticed from my other posts, my girls are having a blast.  Here is yet another that they couldn’t wait to try out.

What you will need (some items are not pictured…sorry!):

1/2 Cup milk, 1/2 Cup heavy whipping cream, 1/4 Cup sugar, 1/4 Teaspoon vanilla, 1/2 to 3/4 Cup sodium chloride (NaCl) as table salt or rock salt (we used sea salt), 2 Cups ice, 1-Quart Ziploc bag, 1-Gallon Ziploc bag, Thermometer, Measuring cups and spoons, Bowls and spoons for eating your treat!

Procedure: 

Add 1/4 cup sugar, 1/2 cup milk, 1/2 cup whipping cream, and 1/4 teaspoon vanilla to the quart zipper bag. Seal the bag securely.

 


Put 2 cups of ice into the gallon plastic bag.  Use a thermometer to measure and record the temperature of the ice in the gallon bag.  Add 1/2 to 3/4 cup salt (sodium chloride) to the bag of ice.


Place the sealed quart bag inside the gallon bag of ice and salt. Seal the gallon bag securely.

Gently rock the gallon bag from side to side.  It’s best to hold it by the top seal or to have gloves or a cloth between the bag and your hands because the bag will be cold enough to damage your skin.  Continue to rock the bag for 10-15 minutes or until the contents of the quart bag have solidified into ice cream.


Continue to rock the bag for 10-15 minutes or until the contents of the quart bag have solidified into ice cream.  Open the gallon bag and use the thermometer to measure and record the temperature of the ice/salt mixture.


Remove the quart bag, open it, serve the contents into bowls, add your favorite toppings and enjoy!
