Chemical Changes Reading for 7th Grade Science
A short reading packet for 7th graders that explains the difference between physical and chemical changes using everyday examples like melting ice and cracking eggs. Students build science vocabulary around key terms such as chemical bonds and new substances, and the content is well suited to a single class period or a focused reading block.
“Using Chemical Changes by Audrey Carangelo create a worksheet.”
Teacher Guide & Tips
- Use this as an introductory or review reading before a hands-on lab on physical versus chemical changes, or as a warm-up that activates students' prior knowledge of matter.
- Discussion question: Why does melting an ice cube count as a physical change while burning paper counts as a chemical change? Ask students to explain their reasoning using the idea of chemical bonds.
- Scaffold for struggling readers: Have them highlight the bolded key terms first, then complete a two-column chart sorting everyday examples into physical or chemical changes before reading the full passage.
- Extension for advanced students: Ask them to predict whether dissolving sugar in water is a physical or chemical change, and to justify the prediction with evidence from the text.
- Estimated time: about 20 to 30 minutes for reading and discussion, plus 10 minutes for the sorting or question activity.
