Instructional Ideas
- Use the lab at the middle school level to work your class' observational skills, or as an examination of the solubility rules in the upper grades
- Allow time to discuss how reactions 9 and 10 could be used at the industrial level to produce solid copper and silver from their salts
Classroom Considerations
- To avoid confusion, ensure pupils in lower grades are aware of the Stock system for naming transition metals
- Remind groups to start with clean, deionized well plates for the best results
Pros
- The lab is a good choice for larger classes and shorter lab periods due to its microscale nature
- Includes all printables with the teacher's guide
- Set up and clean up are easy, giving you more time to mingle and assess student progress
Cons
- None
