Lesson 8 Lab: The Hertzsprung-Russell (H-R) Diagram

Lesson 8 Lab: The Hertzsprung-Russell (H-R) Diagram examines the properties of stars using a powerful tool called the H-R diagram. One of the best ways to summarize all of these details about how a star or protostar changes with time is to use an H-R diagram. In Lab 3 you will explore the H-R Diagram and learn how the diagram can be used to evaluate the properties of various types of stars such as the Sun.

Getting started with Lesson 8 Lab: H-R Diagram:

·         First, select the following link and work through the background sections on Spectral Classification, Luminosity, and the Hertzsprung-Russell Diagram at:

o    The H-R Diagram

                        Next, open the following link and familiarize yourself with the capabilities of the Hertzsprung-Russell Diagram Explorer through experimentation:

o    H-R Diagram Explorer

                        After familiarizing yourself with the simulation interactive open the Lab 8 - Assignment Sheet DropBox Deliverable: Lab 8 - NAAP H-R Diagram Assignment Sheet.

Note: The Lab Simulators require Flash Player which is integrated into Windows 10 and work best with Internet Explorer (IE). To avoid technical issues IE is recommended for running the simulations. If you try another browser you will need to set up flash player options for that browser yourself. For example, if you are using Chrome, go to the upper left of the URL browser entry, select "Not Secure" then select "Allow" to give Chrome permission to open the simulator.

Submit your Lab Worksheet

·         Submit the completed Assignment Sheet for Lab 3 by selecting the Lesson 8 Lab: The H-R Diagram link above, and select Browse My Computer to attach your saved file. Make sure to select SUBMIT. Note: Save your file as a .rtf file or .doc to ensure that it can be opened at any computer.

Labs do not have a time limit but are due on the due date of the lesson posted in the Syllabus Page 2.
