Light Pollution and Observing
Some of your older family members and friends probably tell “tales” of seeing billions of stars, every night, in the nighttime sky. While highly exaggerated, these tales are based in reality. Overall light pollution has dramatically increased over the years, as the pervasiveness of artificial light has brightened our streets, homes, and businesses yet, unfortunately, dimmed our chances of having the spectacular views of yesteryear.
In this lab, you will examine light pollution and issues surrounding light pollution, taking photos of light pollution around your home, local shopping centers, and on highways. You will also learn how the Moon creates a lot of light – natural light pollution – when trying to observe stars and fainter objects. (1)
At the end of this module, students will be able to:
- Record data pertaining to light pollution and viewing of stars
- Research the effects of light pollution
- Catalogue sources of man-made light pollution
- Compare and contrast conditions of natural light pollution (1)
