Four page lab where students plot stars on an HR Diagram and then answer questions. This lab is good for students to learn how to read the chart. They are also asked so higher level questions about the size and brightness of stars that the diagram hints at. See preview file to see this lab. No Key.
The Hertzsprung-Russell diagram is a scatter graph of stars showing the relationship between the stars' brightness and their relative ages. This lab gives the kids a chance to practice plotting stars on the HR diagram.
The Hertzsprung-Russell (H-R) diagram is a graph that is widely used in astronomy to categorize and graph stars. The plot is made by assuming that all stars are at a set distance of 10 parsecs (32.6 light years) from earth. By doing this, comparisons can be made of the size of the star with relat
