Added salt to ice to keep it cooler for longer so we could use it to make homemade ice cream

Science

• The child learned that adding salt to ice can keep it cooler for longer, which is a concept of thermodynamics and heat transfer.
• They discovered that the purpose of keeping the ice cooler for longer was to use it in making homemade ice cream, which relates to the concept of phase changes and freezing point depression.
• The child may have observed that the salted ice melted slower than regular ice, indicating that the salt lowers the freezing point of water, another concept of thermodynamics.
• They learned that salt acts as a catalyst in the freezing process, which affects the texture and consistency of the ice cream

Continued development could include experimenting with different ratios of salt to ice to determine the optimal balance for making the creamiest ice cream. They could also explore other methods of making ice cream, such as using liquid nitrogen or an ice cream maker, to compare the results and understand the science behind each method. Additionally, they could learn about the different ingredients used in homemade ice cream and their individual roles in the freezing process.
