In 5th grade, we spent a couple of weeks learning about matter. We focused a good portion of time on the chemical and physical changes that happen all around us; for example, popping popcorn (physical change) and using gasoline in a car (chemical change). The other day, we decided to create our own physical change--making ice cream! Everyone took their bags of milk, sugar, vanilla, and icy salt to make the delicious treat. We had a grand ol' time tossing, and then eating our very own "school-made" ice cream!
