To finish our Liquids and Solids unit we decided to make homemade ice cream with our learning buddies. The Secret Agents had fun learning about how liquids can turn into solids and exploring matter. Students also got to learn about following the step to a recipe. Here is the recipe they students followed to make their ice cream:
What You’ll Need-
Ice Cubes
1 Cup half and half or milk
1/2 cup Kosher salt
2 tablespoons sugar
1/2 teaspoon vanilla extract
1 pint-size Ziploc bag
1 gallon-size Ziploc bag
Small towel
Any of your favourite ice cream treats
Step One- Measure all of the ingredients. After combine the half and half, sugar, and vanilla extract in the pint-size bag. Seal the bag tightly, so that none of the liquid will leak out. Keep the bags in the refrigerator until you are ready to continue onto the next step.
Step Two- Add four cups of ice cubes to one of the large, gallon-size bag. Then add the one half cup of salt to the bag.
Step Three- Put one of the small bags that was prepared earlier into the large bag with the ice cubes. Be sure that both bags are sealed tightly.
Step Four- Wrap the bag in a small towel and then shake the bag until the liquid turns into a solid (ice cream). Once it has turned into ice cream add in any topping into your bag of your choosing.
Step Five- Eat and enjoy your ice cream! Then clean up any mess and put away the remaining ingredients.
**You could do an experiment and shake the liquid mixture in a bag of ice with salt and without salt. Then students could compare the difference and discuss what the ice did to the ice cubes. Students could explore how the bags feel and if one bag is colder than the other bag.
