Instructional Ideas

  • Incorporate the resource into a forensic chemistry unit or class
  • Provide examples of actual spectra for the class to examine; pair learners up and challenge them to determine the identity of the substance they were given
 
Classroom Considerations

  • Some prior knowledge of atomic mass, isotopes, and ionization would be helpful for viewers
Pros

  • The video is technical enough to illustrate how substances are analyzed, but not to the point that learners at the high school level would have difficulty comprehending
  • Profiles two uses of spectrometry
Cons

  • None
