We all love ice cream, right? So what’s more fun than combining homeschool science with a tasty treat? Teach your kids about the freezing point of different substances, in this case, with the intention of producing ice cream! Here’s how it works:
What you need:
- 1 quart resealable plastic bag
- 1 gallon resealable plastic bag
- ¼ cup of sugar
- ¼ teaspoon of vanilla flavoring
- ½ cup of whole milk
- Rock salt
- Ice cubes
What to do:
- Place the sugar, milk, and vanilla into the 1 quart plastic bag. Seal the bag and mix it well.
- Put 2 cups of ice into the 1 gallon plastic bag, plus ½-¾ cup of rock salt. The salt lowers the the freezing point of the ice, causing it to start to melt.
- Place the closed milk bag into the gallon bag and seal the larger bag.
- Hold the large bag at the top and rock the bag from side to side. Continue rocking it until the milk mixture solidifies.
- Your ice cream is ready to eat! You can repeat this experiment with different flavors as many times as you like. This is one experiment your kids are sure to want to do over and over again!
