States of Matter in a Bag

Solids, liquids and gases have unique properties that differentiate them from each other. However, these three forms of matter are interchangeable. Second graders may find this concept difficult to understand. Using ice cubes in a Ziploc bag, you can let your kids watch the conversion of solid to liquid and then to gas, all inside the bag. This science activity also makes it easy for kids to study the properties of each of the different states of matter.
