The Effects of Colloidal Silver on Microbial Growth: Investigating Snake Oil Science

This lab, presented by the National Nanotechnology Coordinated Infrastructure, covers the concepts of material properties. Students will use "electrochemistry techniques to generate colloidal silver and then utilize the colloidal silver to determine if the growth of the bacteria Saccharomyces cerevisiae or Escherichia coli can be inhibited." A Teacher Preparation Guide, Student Guides, Worksheets, and Next Generation Science Standards applicable to the lesson are included.
