Making Ice Cream

Ideal for Preschool/Pre-K, School-Age

Young toddler girl with pig-tails eating an ice-cream cone.

Materials Needed:

  • Half and half – ½ Cup (or try Greek yogurt for a healthier option)
  • Vanilla – ½ teaspoon
  • Sugar –1 Tablespoon
  • Ice – 3 Cups
  • Salt (the coarser the better)
  • 1-Gallon storage bag with zipper
  • 1-Quart storage bag with zipper

Directions:

  1. Mix 3 cups of ice in a gallon storage bag with 1 cup of salt. Squeeze as much air out as possible.
  2. Mix ½ cup half and half, ½ teaspoon vanilla, and 1 Tablespoon sugar in the quart storage bag. Try to squeeze as much air out as possible. Close it tight.
  3. Put the sealed quart mixture bag into the gallon bag containing the ice and close it tight. Shake for 5 to 7 minutes.
  4. Grab a spoon and enjoy your ice cream! Try this experiment with other milk products like yogurt.

Science question to ponder: How can you make ice cold enough to make ice cream?

What is happening? The temperature of the saltwater is colder than freshwater. The bag's temperature is low enough to change the milk mixture from a liquid to a solid. Yum!
