I hope you enjoyed making and eating your ice cream on Friday — I keep telling you science is fun!
- Have you figured out how heat was used? Remember that heat is the movement of thermal energy.
- Besides the changes in temperature what other observations did you make? Do you recall taking any notes that might relate to your observations?
- What was the purpose of the salt?
- Can you draw a picture showing the flow of thermal energy in your experiment?
- Were there any anomalies (unexpected results)? What might have caused them?
Mr, Grant. Can I get the procedures from you so I can make more Ice Cream at home?

This recipe is enough for one student, so that each student can make their own.
1/2 cup milk
1/2 teaspoon vanilla
1 tablespoon sugar
4 cups crushed ice
4 tablespoons salt
2 quart size Zip-loc bags
1 gallon size Zip-loc freezer bag
a hand towel or gloves to keep fingers from freezing as well!
Mix the milk, vanilla and sugar together in one of the quart size bags. Seal tightly, allowing as little air to remain in the bag as possible. Too much air left inside may force the bag open during shaking. Place this bag inside the other quart size bag, again leaving as little air inside as possible and sealing well. By double-bagging, the risk of salt and ice leaking into the ice cream is minimized. Put the two bags inside the gallon size bag and fill the bag with ice, then sprinkle salt on top. Again let all the air escape and seal the bag. Wrap the bag in the towel or put your gloves on, and shake and massage the bag, making sure the ice surrounds the cream mixture. Five to eight minutes is adequate time for the mixture to freeze into ice cream.
Tips
Freezer bags work best because they are thicker and less likely to develop small holes, allowing the bags to leak. You can get away with using regular Zip-loc bags for the smaller quart sizes, because you are double-bagging. Especially if you plan to do this indoors, we strongly recommend using gallon size freezer bags.
Hey…that ice cream was really good. i made some at home but for some reason it came out salty. YUCK!!!!!*****
where can you find the lab reference sheet on this website?
Lab template is on the home study page. Look at the righthand sidebar under class documents.
I really can’t wait for this activity. I scream for Ice cream .
