THE HERTZSPRUNG-RUSSELL DIAGRAM
WHAT'S TRENDING IN SPACE
STAR LIFE CYCLE TO THE H-R DIAGRAM
COOL CAREER PATHWAYS FOR TODAY'S ACTIVITY
FOR YOUR NOTEBOOK:
Hertzsprung-Russell Diagram - Two Scientists were able to plot out all the stars they could see on a diagram. This diagram had 2 main parameters.
Y Axis - Absolute Magnitude or actual brightness.
X Axis - Surface Temperature (K)
Using these two factors, Hertzsprung and Russell were able to distinguish the life cycle of our stars.
ASSIGNMENT
YOU ARE CREATING YOUR OWN H-R DIAGRAM
You need 4 things:
The H-R Diagram Template (Button Below)
The Data Table (Button Below)
A Pencil
Here are your Directions:
Determine the Spectral Class for each of the stars based on temperature.
Determine the color of the stars based on the Spectral Class
Plot the points from the Data Table onto your H-R Diagram Template
Compare your Diagram to THIS ONE to figure out what each of these stars is classified as.
Answer the question: How are scientists able to see the life cycle of stars using the Hertzsprung-Russell Diagram.
THE ONES WE SEE IN THE DIAGRAM
REGULAR SEQUENCE STAR
MASSIVE REGULAR SEQUENCE STAR
RED GIANT
SUPERGIANT
PLANETARY NEBULA
