Description: In this Science NetLinks lesson, students determine the age of a star cluster by observing, measuring, and plotting astronomical data. They examine the Jewelbox cluster, located within the southern constellation Crux, and determine its age using a relationship between temperature, color, and luminosity. Before beginning this lesson, students should understand the life cycle and composition of stars. Students should also understand the relationship between temperature and color.
