In this week’s History Adventures program you’ll get to learn about George Washington Carver and his contributions to science. After the history lesson, Sophie and Abby will lead you through a hands-on chemistry activity: making homemade ice cream!
Homemade Ice Cream Ingredients & Materials:
- 1/2 cup milk
- 1/2 cup whipping cream (heavy cream)
- 1/4 cup sugar
- 1/4 teaspoon vanilla or vanilla flavoring (vanillin)
- 1/2 to 3/4 cup sodium chloride (NaCl) as table salt or rock salt
- 2 cups ice
- 1-quart ZiplocTM bag
- 1-gallon ZiplocTM bag
- thermometer (Optional if you don’t have one)
- measuring cups and spoons
- dish towel
- cups and spoons for eating your treat!
- Add 1/4 cup sugar, 1/2 cup milk, 1/2 cup whipping cream, and 1/4 teaspoon vanilla to the quart ziplocTM bag. Seal the bag securely.
- Put 2 cups of ice into the gallon ziplocTM bag.
- Use a thermometer to measure and record the temperature of the ice in the gallon bag. (Optional?)
- 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 dish 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. *Voice over explanation here*
- Open the gallon bag and use the thermometer to measure and record the temperature of the ice/salt mixture. (Optional?)
- Remove the quart bag, open it, serve the contents into cups with spoons and ENJOY!
