HS, Astronomy Std 34: Evaluate the life cycle of stars using the Hertzsprung-Russell diagram (H-R diagram).

Lesson Plans: H-R Diagram Plotting near stars and bright stars on a color magnitude diagram Cluster Color-Magnitude Diagrams and the Age of Stars The student will find the ages of two clusters by plotting stellar data on a color-magnitude diagram. Jewels of the Night The Jewels of the Night is a hands-on, teacher-tested activity for middle school and older students. Students measure the color and brightness of stars in the Jewelbox Cluster from a color image. They determine the age of the cluster by plotting their measurements in a color-brightness diagram. The activity develops classification and graphing skills and fosters observation, communication, and cooperative learning skills. Students are exposed to ideas about the nature of stars, temperature and color, stellar evolution, the time scales of astronomical phenomena, and how astronomers can determine the ages of objects in the universe.

Resources: Hertzprung-Russel Diagram: A colorful model of the H-R diagram. The Life of a Star: This page (as the title says) is all about the life of a star. It will show all the stages that a small star, and a massive star have to go through during their lifetime.
