1. Learning Goals:
4. Complex Knowledge: demonstrations of learning that go aboveand above and beyond what was explicitly taught. 3. Knowledge: meeting the learning goals and expectations. 2. Foundational knowledge: simpler procedures, isolated details, vocabulary. 1. Limited knowledge: know very little details but working toward a higher level.
How do stars differ from moons and planets, and from one another?
How does the classification of stars help us understand how they evolve over their lifetimes?
What are the different types of stars?
What happens when different types of stars die?
Why is it important for us to understand stars?

2. Due last night! You should have the stars all plotted like this!

3. Hertzsprung-Russell (HR) Diagrams!
The most important chart in all of astronomy

4. The Hertzsprung–Russell diagram
a scatter graph of stars showing the relationship between:
absolute magnitude / luminosity
(Y)
versus
spectral classification / temperature
(X)

6. Hertzsprung–Russell diagrams
 are GRAPHS showing characteristics, not pictures or maps of the locations of the stars.
Help you determine:
luminosity class
Temperature
Spectral class
Lifetime
Size
Absolute magnitude

17. Stars are classified into luminosity classes.

19. Supergiants
Giants
Subgiants
Main Sequence
White Dwarf

20. My favorite one! It has everything!!! 

21. This one is very simplified, but easy to read

22. This one has the temperature on a regular increasing value, so it’s backwards, or forwards depending on your point of view.

23. This one has some added classifications (for stars that are so cool, we can only see them in Infra-red radiation)

24. Now: You get to make one. start with this… add in:
Star groups
Sun radii lines
Our sun
Some other stars you have information for from your chart
Instability zone
Color
Spectral Classes (o,b,a,f,g,k,m)
Luminosity Classes (I,II,III,IV,V,VI,VII)

25. Now: You get to make one

28. Add your 8 favorite stars. 

29. Star groups
Sun radii lines
Our sun
Some other stars you have information for from your chart
Instability zone
Color
Spectral Classes (o,b,a,f,g,k,m)
Luminosity Classes (I,II,III,IV,V,VI,VII)
