Compare observations of reactants and products and describe the pattern you notice
Free printable Grade 7 science worksheet for "Compare observations of reactants and products and describe the pattern you notice" — practice chemical reactions. No-prep, print or assign online.
Middle school students compare observations of reactants and products in chemical reactions to identify patterns in how matter is conserved and rearranged in this hard-level Physical Science worksheet. Teachers can use it to reinforce the law of conservation of mass and to develop students ability to read observational evidence and make pattern-based generalizations. It belongs in a Chemical Reactions unit and builds the scientific reasoning skills needed for more advanced chemistry content.
Learning objectives
- Compare the observable properties of reactants and products in described chemical reactions
- Identify patterns that demonstrate conservation of matter across chemical changes
- Describe the evidence that a chemical reaction has occurred based on observed changes
