Instructional Ideas

• Have early finishers research the uses of silver nanoparticles as nanotechnology

Classroom Considerations

• Recommends previous experience with spectroscopy
• Allow time to prepare chemicals and materials in advance

Pros

• Provides in-depth background information for both teachers and students
• Includes handouts for pupils to follow during the activity

Cons

• None
