Second graders are gathering evidence to show that matter can indeed change, just like their objects changed when the pieces where rearranged. But can the pieces stay the same and just look different?
By building "snowmen" made of ice, second graders will make observations throughout the day to see how matter can change. In this case, the water used to make the snowmen will undergo a physical change. Each "snowball" began as liquid water in a balloon. Put in the freezer, the water changed to ice. Now out of the freezer, what will happen to them? Only time will tell!
