Instructional Ideas

• Challenge learners to find as many different spectra for light sources as possible
  

Classroom Considerations

• Pupils must have completed the "Building a Fancy Spectrograph" activity and its associated homework assignment
• Different light sources are necessary, such as Christmas lights, candles, glow sticks, and neon bulbs
  

Pros

• Provides reproducible student worksheets
  
• Includes a set of sample answers for instructors to reference
  

Cons

• None
