SECRETS of the SUN – video Available online at: .org/video/2226474716
Nova reviews what scientists have learned in recent years about the sun's behavior and how it works. Most significantly, astronomers are at last beginning to understand the solar phenomenon that impact our civilization; solar flares and coronal mass ejections (CMEs). 54 minutes
Video Guide: Tape this paper in your science notebook on a left side sheet. Then write the answers to the question on the right hand sheet of paper. [If you are doing this as make-up and want full credit, write your answers on a separate sheet of paper and have your parent or tutoring center adult sign and date the paper – verifying that you watched the video.]
Introduction:
1. What are the two parts of a solar storm?
2. What evidence is there for a solar storm in 1859?
3. What effect could a large CME wave have on today’s electric power grid?
4. Why is a CME a bigger issue today than in the past? Give 3 specific examples of technologies that would be affected.
Sun’s Interior
5. What is the importance of the rippling vibrations on the surface of the sun?
6. What is plasma?
Photon’s Journey
7. How do hydrogen atoms in the center of the sun produce sunlight?
8. Why doesn’t the Sun blow apart from nuclear fusion?
9. Why does it take so long to get through the radiative zone?
10. Describe the movement of plasma in the convection zone.
Destructive Power of the Sun
11. Surveillance of sun improves with the launch of Solar Dynamics Observatory (SDO), what was one important aspect of SDO’s new information?
12. What things work to produce the Sun’s magnetic fields?
13. How are solar flares produced by field lines?
14. What is behind the energy of a CME?
15. Why is the corona so much hotter than the surface of the sun?
16. Why are sunspots a clue to predicting solar storms?
17. What determines whether or not most of a CME’s energy will strike the Earth?
18. What will be produced by a moderate solar storm such as the February 2011 one being tracked in this video?
19. Why might it take so long to restore power if many transformers are burned out?
20. What is one question you still have about the Sun?
