Understand what light pollution is (excessive artificial light) and how it, along with smoke and dust, negatively affects the visibility of stars, especially in urban areas.
Appreciate that different cultures, including ancient travellers, sailors, and Indian tribes, created their own stories and used star patterns for navigation and cultural purposes.
