🔬 Key Chemical Evidence Students Will Learn
Students investigate how to recognize when a chemical reaction has occurred using observable signs that point to particle-level changes.
✔ Color change as evidence of new substance formation
✔ Gas production (bubbling) as a reaction indicator
✔ Precipitate formation and solid creation in mixtures
✔ Temperature change (heat release or absorption)
✔ Persistence of new materials as stronger evidence than temporary effects

🧠 Skills Developed Through This Activity
✔ Scientific observation and evidence-based reasoning
✔ Connecting macroscopic changes to particle-level explanations
✔ Critical thinking and analysis of experimental results
✔ Academic vocabulary development in chemistry
✔ Writing scientific explanations using evidence
✔ Distinguishing between chemical and physical changes
