The Electromagnetic Spectrum

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They start by constructing their own spectroscopes, and it just gets better from there.

Instructional Ideas

  • Research the impact various wavelengths from the electromagnetic spectrum have on the human body
Classroom Considerations

  • Follow all safety guidelines and regulations when using materials, especially razor blades, that could harm pupils
  • The diffraction grating should be the holographic type for the best effect
  • A dark classroom would be best for this lesson
  • A soldering iron is required, but soldering could be done ahead of time rather than as part of the activity
  • The second in a series of five lessons
Pros

  • Resource includes an answer key
  • The content covered is higher level, but the lesson presents it so well that the younger students will be able to understand it
  • Highly engaging activities doing real science rather than just reading, observing, or memorizing
Cons

  • None
