Students complete sentences about state changes and match states to their properties. Part A has nine fill-in-the-blank problems about melting, condensation, and evaporation. Part B is a matching activity connecting solid, liquid, gas, and melting to their defining descriptions.
Naming change processes like melting and condensation alongside state properties builds the vocabulary students need to reason confidently about state changes on harder sheets.

States of Matter
Part A: Fill in the Blank
Write the missing word or number on each line.
