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
