1. 2/5/14 Shine Like A Star With Your Warm-Up 1.Are there more grains of sand on Earth or stars in the universe? 2.What is a leap year? Why do we have leap years? 3.How big is the Earth compared to the Sun? 4.How big is our Sun compared to other stars? 5.Why is the Equator warmer than the North and South Poles?

2. Do Now 2/6/14 Define the following words: 1.Astronomy 2.Geocentric model 3.Heliocentric model 4.Revolution 5.Rotation

3. Do Now 2/7/14 1.Put the following in order from largest to smallest: solar system, sun, galaxy, universe, planet 2.Where did the study of astronomy originate? 3.If you could travel to any planet which one would it be? Why?

4. Look at the 7 pictures on the paper, answer question 1-3 on your paper

5. Astronomy ASTRONOMY

11. Astronomy fill-in-the-blank Start on page 614 First section chapter 21 2 nd section chapter 23

13. First, some perspective...

19. Make Sure You Know This! Universe Galaxy Solar System Sun Planets How Old It Is How Big It Is

21. Scale of the Universe: One more way to think about it... Think about Independence High School, which was built first, Room 209, or the school? My room is like a planet, and the school is like the solar system

22. Forget

23. The Earth in the Universe The Motion of our Home...

24. Earth Motions: Draw This In Your Notes The MotionWhat It IsWhat It CausesPicture / Diagram Rotation (Ro-tay-shun) Revolution (Rev-o-lew-shun) Precession (Pre-cess-shun) Nutation (New-tay-shun)

25. Quick Video About Rotation http://player.discoveryeducation.com/index.cf m?guidAssetId=EF21D20B-2294-47B7-85A1- 7C41B7A537A6&blnFromSearch=1&productco de=DETB http://player.discoveryeducation.com/index.cf m?guidAssetId=EF21D20B-2294-47B7-85A1- 7C41B7A537A6&blnFromSearch=1&productco de=DETB

26. Rotation Counter-Clockwise Spinning on the axis Takes about 24 hours, result is Day and Night Without Rotation, there would be a burning hot “Day” side and a freezing cold “Night side of the Earth

27. Why does the Earth spin? http://www.youtube.com/watch?v=T QxeutcYP6I

28. Revolution The Earth’s counter-clockwise elliptical (oval shaped) orbit around the sun Takes 365 ¼ days, helps give us the seasons If Revolution stopped one hemisphere would experience eternal summer, while the other would experience winter

29. Revolution

31. Precession Earth is tilted 23.5⁰ off center, this means parts of the Earth are closer to the Sun than other parts Precession gives us seasons, because of the tilt, one hemisphere or the other receives more sun light (summer), the other hemisphere gets less light (winter) If precession stopped, we wouldn’t have seasons...

32. Nutation Nutation is a wobble in the Earth’s precession caused entirely by the moon’s gravity tugging on the Earth If nutation stopped, the “changing” location of stars in the Earth’s night sky would be limited

35. Music Time... 1. Split into pairs (choose wisely, this will be graded) 2. On your Album/ Paper, create 8 (or more) song titles that show your knowledge of: – Where the Earth is in the universe, and the size of the Earth compared to the rest of the universe- at least 1 title – The Earth’s motions (Rotation, Revolution, Precession, Nutation)- at least 4 titles, one about each movement – What happens because of the Earth’s movements (Eclipses, Seasons, Tides, etc.)- at least 2 title – What might happen if these movements stopped- at least 1 title Funny is great, showing your knowledge is a must!!! You can use your notes (and the book if you really want)
