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?

Bell Work 3-3-16 You observe two stars in the constellation Leo, and you are curious about their luminosities. Specifically, what two measurements do you need to make in order to determine that? Hint: Think about what you need to know to determine luminosity How do you measure those two things simply from the light that we receive?

Answer: You need to know size You look at the wavelength of light You need to know temperature You need to know size You look at the wavelength of light This tells you it’s color Which will then allow you to determine it’s temperature You look at it’s spectral lines The thinner the line, the less dense the atmosphere and the larger the star The thicker the line, the more dense the atmosphere and the smaller the star

Yesterday: You learned about different types of stars symbol Properties Examples Hypergiant Supergiant I Giant III Subgiant IV Main sequence V White dwarf VII

You are doing this on your own! We will go over these things tomorrow/Monday You will receive class participation points today if you work. Each time I see you not working, I will take away a point or ten…
