Activities in the Changes unit expand students' understanding of matter by exploring changes it undergoes as it transitions from solids to liquids and gases. Students consider the changes to a single substance, water, as they observe it freeze, melt, evaporate, and condense. Then, through a sequence of lessons, students investigate changes involving mixtures of different types of matter.
