| Abstract | A lot of good elementary science involves studying solids, liquids, and gases, and some inquiry-based activities that are easy to set up and do. In this article, the author presents activities pertaining to simple phase change. Using water as the example, these activities introduce upper-grade students to the idea of the arrangement of molecules in a solid, liquid, and gas and to the idea that the mass of ice does not change when it melts into a liquid. Both activities assume that students have already learned about the general differences between solids, liquids, and gases and have a general understanding of melting and freezing. The activities are best used with students in grades 3-6 and and will lay groundwork for students' later learning experiences on these topics. Not only do these activities help students learn about the arrangement of molecules in different phases and about the conservation of mass, but they also generate a positive classroom environment and enthusiasm among students.
