Instructional Ideas
- Make the lab one of the first of the year to squash any misconceptions the class may have about chemical versus physical changes
- Demonstrate additional physical changes after the lab is complete to cover a broader range of changes
Classroom Considerations
- Try having different lab groups start at different reactions to prevent a pile-up as they retrieve their materials
- Prepare all of the dilute solutions in advance; most have excellent storage times
Pros
- The activity exemplifies the principles of green chemistry
- Set up and delivery of the lab is a snap with the detailed materials list, printable materials, and answer keys in the teacher's guide
