We made ice cream in a plastic bag as a fun science project. The best part is that we didn't need an ice cream maker or even a freezer. This was a fun and tasty food science project that explores freezing point.We used milk, honey, vanilla, salt, ice.When you add salt to the ice, it lowers the freezing point of the ice, so even more energy has to be absorbed from the environment in order for the ice to melt. The larger crystals take more time to dissolve in the water around the ice, which allows for even cooling of the ice cream.
Children's interest: All the children were very excited to take part in the project and to see how milk turn into ice cream.They mixed ingredients and touched the ice crystals saying they are very cold and they tasted the ice cream with pleasure.
Purpose:To learn through fun about liquid and solid states.
LPFÖ: Develop their understanding of science and relationship to nature, as well as knowledge of plants, animals, and also simple chemical processes and physical phenomena.
