10/20 - Look at the H-R Diagram (old ES pgs. 578-579):
What is on the x and y axis of the H-R Diagram?
List the kinds of stars an H-R Diagram shows.
Tape the H-R diagram into your notebook and then do the following:
Put the title H-R Diagram above it in your notebook.
Highlight or outline the sun with yellow.
Highlight or outline the Blue Giant region in blue.
Highlight or outline the Red Giant region in orange or red.
Outline the area and label where White Dwarfs would be found on the H-R diagram.
R☉ means sun radii or solar radius. Interpret the diagram: How much brighter and bigger than the sun is the smallest Blue Giant? How about the star Betelgeuse?
