3. 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:
- a. Reflection
- b. Collimation
- c. 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?
