In this activity, students will be able to label a diagram showing how materials change state by adding or removing heat, which changes the kinetic energy of the atoms in that material. Students will label the steps of each phase change (melting, boiling/vaporization, sublimation, condensation, freezing and deposition). Students will understand the main concepts that as you add heat, the kinetic energy of the atoms increases. As you remove heat, the kinetic energy of the atoms decreases. H
