1 The Phases of the Moon

2 Is the Earth’s shadow is the cause of the Moon’s phases?

3 NO

4 True Scale of Earth-Moon System:

5 Moon Takes About a Month (29.3 days) to go through all phases

6 Phases: New – Whole face is dark Crescent – Looks like fingernail First & Third Quarter -- Half lit Gibbous – Latin gibbosus humpbacked Full – Face is totally lit up

7 Waxing – Getting Stronger (“wax poetic”) Waning – Getting Weaker (“on the wane”)

9 Moon Phases

10 Phases caused by Moon’s orbit around Earth

13 One evening you go out and seen the full moon in the constellation Taurus. Two months later, you see the full moon again. It is: A. Still in Taurus B. In a different constellation C. It might be in Taurus, or a different constellation.

14 The time the moon is high above the southern horizon depends on what phase it is in.;

15 When is the third quarter moon directly overhead? A. 6 AM B. Noon C. 6 PM D. Midnight

16 When is the waxing crescent directly overhead? A. 9 PM B. 3 AM C. 9 AM D. 3 PM

17 What time does the full moon rise? A. 6 AM B. Noon C. 6 PM D. Midnight

18 The moon is full on March 30. What constellation is it in? A. Taurus B. Virgo C. Capricornus D. Gemini

19 The Sun is in Gemini. You observe the moon is in Cancer. What phase is the moon in? The zodiacal constellations in the order the sun and moon pass through Pisces Aries Taurus Gemini Cancer Leo Virgo Libra Scorpius Sagittarius Capricornus Aquarius A.first quarter B.third quarter C.waning crescent D.waxing crescent E.full

21 The Earth’s shadow is the cause of the Moon’s phases A. Yes B. No

23 True Scale of Earth-Moon System:

24 Eclipses

25 Eclipses occur when Sun, Earth, Moon are in Syzygy (i.e. all three are in a line)

26 Moon in middle =“Solar eclipse” Earth in middle =“Lunar Eclipse” It is an eclipse of whatever body appears dark as seen from earth

30 Partial Eclipse – Moon not lined up to block out whole sun

31 Eclipse movie (click to start)

32 Where an Eclipse looks Total, and Where it Looks Partial:

33 Annular Eclipse = Moon too far away to eclipse whole sun

34 During a solar eclipse, the moon must be in the ____ phase. A. Full B. New C. Crescent D. Gibbous E. First Quarter

35 Visualize 4 Layers

36 Lunar Eclipse: Shadow of Earth Falls on Moon

37

38

39 During a lunar eclipse, the moon must be in the ____ phase. A. Full B. New C. Crescent D. Gibbous E. First Quarter

40 Moon’s orbit is tilted 5 degrees from the ecliptic plane

41 If the moon’s orbital plane was the same as the ecliptic plane, eclipses: 1. Would occur more often 2. Would occur less often 3. Would occur at the same rate

42 Eclipses would occur more often. Currently, can only occur when moon is at “nodes” (where moon’s path crosses ecliptic)

43

44 If you were on the moon, you would see Earth go through phases.

45 What phase is the Moon in? 1. New, 2. Cresc, 3. Quarter 4. Gibbous 5 Full

46 In the movie Apocalypso, the main character is saved by a solar eclipse during one day, and runs by the light of the full moon that night. Is that possible ? A. Yes B. No

47 The Sun is in Pisces. You observe a first quarter moon. What constellation is it in? The zodiacal constellations in the order the sun and moon pass through Pisces Aries Taurus Gemini Cancer Leo Virgo Libra Scorpius Sagittarius Capricornus Aquarius A. Pisces B. Gemini C. Virgo D.Sagittarius

48 The Sun is in Gemini. You observe a total lunar eclipse. What constellation is the moon in? The zodiacal constellations in the order the sun and moon pass through Pisces Aries Taurus Gemini Cancer Leo Virgo Libra Scorpius Sagittarius Capricornus Aquarius A. Pisces B. Gemini C. Virgo D.Sagittarius

49 The moon is in the middle of a lunar eclipse on March 30. What constellation is it in? A. Taurus B. Virgo C. Capricornus D. Virgo
