Procedure for Making Ice Cream in a Bag

1. Place the cream, sugar, and any flavoring you’re using into the smaller baggie. Seal it tightly and be sure there are no leaks. (We put ours inside another baggie as a precaution.)

2. Fill the large baggie about a third of the way with ice and pour in the salt.

3. Place the smaller baggie inside the larger one. Add a bit more ice (so the bag is about 2/3 full), and seal the large baggie with both the small baggie and ice inside.

 

4. Use your hands to move the baggie around continuously. Check the ingredients occasionally to see if the mixture resembles  ice cream.

5. Your ice cream should be done in about 20-25 minutes. Eat and enjoy!

Question to Spark More Curiosity & Critical Thinking

1. What state of matter is the mixture at the beginning of the experiment? How about at the end?

2. What happened to the ice in the large baggie as you were making the ice cream? Why do you think this happened?

3. Why do you think salt is necessary in this activity?

What’s Going On?

Salt lowers the freezing temperature of water. When you add salt to your ice, you’re creating a mixture that is colder than just the ice itself. This colder temperature causes the mixture to freeze and become ice cream!

Want to go even further?

Even more activities to inspire creativity and critical thinking for various ages.

1. Experiment with different ratios of salt to ice and see how it affects the freezing of the ice cream.

2. Measure the temperature of the mixture before it freezes and after. Compare the two temperatures.

3. Based on this experiment, why do you think salt is sprinkled on icy roads in winter?

4. Here’s a fun experiment using ice and a string!

5. Here’s another fun science experiment using ice!

  1. Wow! This is so cool. I love homemade ice cream, but I always thought that you needed one of those fancy ice cream makers to do it with. I’m totally doing this with my kiddos! I love the book suggestions too.

  2. I had no idea you could do this without an ice cream maker!

    Thank you for stopping by the Thoughtful Spot Weekly Blog Hop this week. We hope to see you drop by our neck of the woods next week!
