The Universe - Nov. 13 to Dec. 1

Warm-Ups

11/14 -Read "Space Dust" on page 5 and "Galactic Showdown" on Pgs. 20-22 of ScienceWorld March 5, 2014.

1. Make a simple diagram showing the two different ways stars form.

2. How do Blackholes come to be?

3. Where are they found?

4. If they are 'black', how do we know they are out there?

11/17 - The colors that stars twinkle tell us about the surface temperature of the stars. List the colors of the rainbow in order from coldest to hottest.

11/18 - Make a Venn diagram comparing Apparent Magnitude with Absolute Magnitude. (SS pgs. 20-21)

11/19 - Make a picture with labels that shows what happens during Nuclear Fusion. Why is Nuclear Fusion important to star formation? (SS pg. 29)

11/20 - What does an H-R diagram compare about stars? What does it tell us about how stars form? (SS pgs. 34-35)

11/21 - What are the size trends in the H-R diagram? As Absolute Magnitude (Luminostiy) goes up the radius of the star gets.... As stars get more blue (higher temperature) the radius of a star gets....

12/1 - How does the discovery of Cosmic Background Radiation support the Big Bang Theory? (Old ES pg. 587, A Short History of the Universe - sun.org)

12/2 - What causes the Redshift (or the Doppler Effect) to happen? (Old ES pg 493, Notes: NOVA: Hunting the Edge of Space, Part 2 - pbs.org)
