This Physical and Chemical Reactions - Factors Which Affect Reaction Rate lesson plan also includes:
- Join to access all included materials
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the conventional step-by-step manner. A worksheet is provided with questions to help learners process their observations. Although this was written for a high school chemistry course, it seems more appropriate for middle schoolers.
