Ice Cream Making Process Concepts

Brian Williams demonstrates how to make ice cream at home with kids using basic materials. The video covers the ingredients needed, the science of freezing with salt, and the step-by-step process of making ice cream in plastic bags. The activity is designed to teach children about states of matter and the effect of salt on the freezing point of water. The video concludes with a tasting session, highlighting the simplicity and educational value of the experiment.
