Explain why lasers can be dangerous, especially to the eyes, even low-power ones. Outline basic safety rules.
4
Give examples of at least four or five different uses for lasers in everyday life, medicine, industry, or technology.
5
Under strict adult supervision and using only a safe, low-power Class 1 or Class 2 laser pointer, demonstrate how the beam reflects off a mirror and observe how the beam remains narrow over a certain distance (collimation) compared to a flashlight beam.
6
Explain the following terms:
6a
Reflection
6b
Collimation
6c
Diffraction
7
Learn about fiber-optic communication and explain how laser light is used to rapidly transmit vast amounts of information through thin glass fibers.
8
Use a laser engraver to engrave various materials by adjusting intensity levels (optional).
9
Discuss the connection between the text of Psalm 119:105 and lasers. How can the focused, directional nature of a light beam (whether a laser or the lamp mentioned in the verse) serve as a metaphor for the guidance that faith or the Word of God offers in our lives?
