The purpose of the lab was to fully understand the Herztsprung-Russel diagram. We use this diagram to categorize stars with their stellar properties. By examining a star’s temperature, relative size, and luminosity for instance, you can plot them on an HR diagram. During the lab we did four different activities to understand the lab. The first was to look at a group of squares with different sizes, letters, color, and numbers. We categorized them based on color and then in order from smallest to biggest. Then answered questions on how they were in order based on their characteristics. The second part of the lab we looked at an HR diagram and used our knowledge to answer questions about spectral types and luminosity. The third activity, we
