The document describes a lab activity on tracking the night sky using different coordinate systems. It introduces the right ascension/declination (RA/Dec) coordinate system used by astronomers to describe celestial objects. Students learn about and practice using the RA/Dec system on a star wheel and in the Stellarium software to determine coordinates of stars and observe how the night sky appears at different locations, including San Francisco, the North Pole, and the equator. Key findings include that Polaris' declination does not change but its altitude does based on location, and that the visibility of different stars depends on one's latitude.
