In this Chemistry Activity, students will solve 12 questions of STATES OF MATTER (Properties of Matter) and PHASE CHANGE including Melting, Freezing, Vaporization, Condensation, Deposition, and Sublimation between Solids, Liquids, and Gases. This is a valuable self-checking resource for both middle school (Topic Introduction) and high school (Topic Review) on States of Matter and Phase Change!
