Phases of Matter and Molecular Motion Review
A review packet for 7th graders covering the three states of matter, molecular motion, molecular formulas, and chemical versus physical changes, with a table-based comparison of solids, liquids, and gases. It builds vocabulary, model-reading, and explanation skills, and works well as a 45-minute review block or small-group warm-up before a unit test.
“Create review questions covering phases of matter, molecular formulas, matching models to molecular formulas and chemical reactions, and chemical and physical changes”
Teacher Guide & Tips
- Use as a 45-minute review block after a unit on states of matter, or split it across two short warm-ups if time is tight.
- Discussion question: Even though a solid table looks still, why are its molecules still moving, and what changes when you add heat?
- Scaffold for struggling readers: Pre-teach the terms arrangement, energy level, and motion, and have students sketch a quick particle diagram before filling in the comparison table.
- Extension for advanced students: Ask them to match a molecular model to a molecular formula and explain whether the change they describe is physical or chemical.
- Estimated time: About 40-45 minutes for the full set, including a brief whole-class debrief on the table.
