5 States of Matter worksheets with answer keys. Includes a vocabulary study guide sheet, crossword puzzle, matching pairs, scrambled words and a word search. Worksheets are also sold separately. I use the vocabulary sheet either as a study guide for the chapter or a quiz at the end. My students like the puzzles for quiz review. 25 terms with definitions for various states of matter and changes of state. Applicable to chemistry, physics, physical sciences. Good companion for a textbook chapter on this topic. By Maura Bostwick Neill.
