Identify phase changes

Free printable Grade 6 science worksheet for "Identify phase changes" — practice matter and particles. No-prep, print or assign online.

Middle school students examine the transitions between solid, liquid, and gas states in this worksheet on identifying phase changes, connecting particle behavior to observable phenomena like melting, evaporation, and condensation. Teachers can use it during a physical science unit on matter to help students move from naming states to understanding the energy transfers involved. The skill sits at the heart of chemistry and earth science, supporting further study of the water cycle, chemical reactions, and thermodynamics.
