Description

Today, we will be having fun, eating ice cream, and learning about how salt is used to lower the melting point of ice. This project actually makes lots of ice cream – definitely enough for a group of three or four. Since the project only takes about 20 minutes total, it would be best to have larger groups and make two batches of ice cream. Then, the teams will share each batch of the ice cream.

Purpose of Activity

Learn how chemistry makes ice cream so cold (and delicious).
