Instructional Ideas
  • Use the video to demonstrate the formation of NaCl, especially if the experiment cannot be performed in the classroom or lab
Classroom Considerations
  • Video uses chemistry terms associated with chemical reactions, such as ionization energy, Coulombic interactions, electron affinity, exothermic, etc.
  • Be sure learners have enough chemistry knowledge to understand what is occurring in the video
  • This resource is only available on an unencrypted HTTP website. It should be fine for general use, but don’t use it to share any personally identifiable information
  • The reaction produces bright orange flames, which amazes and engages learners
  • Short length of the video makes it a good instruction to a more thorough demonstration or experiment in class
  • Lab performer eats a hard-boiled egg, violating a basic lab safety rule
  • During the demonstration, the performer pulls out a sample of previously prepared salt rather than using the results of the experiment
