1. Moon Phases

2. How it works! Half of the moon is lit up at one time The moon revolves around the Earth We see different sections illuminated depending on its position

3. As the moon rotates it appears to be changing shape.

4. Moon Phases Causes by different angles from which we see the lighted portion of the moon. Depends on moon position As the moon revolves around earth different portions are lit up. As the moon revolves around earth different portions are lit up.

6. Lunar Cycle Moon passes through 4 major shapes Takes 29.5 days Phases always occur in the same order –1. New Moon –2. First Quarter –3. Full Moon –4. Last Quarter

7. New Moon Lighted side of the moon faces away from earth Sun, Earth, and Moon are almost in a strait line. The moon we see looks very dark. (if we see it at all)

8. New Moon

9. First Quarter Right half of the moon is illuminated Left side appears dark From new moon to first quarter the illuminated section will slowly grow in size

10. First Quarter

11. Full Moon The lighted side of the moon faces earth. Behind earth Sun, Earth, and Moon are ALMOST in a straight line.

12. Full Moon

13. Last Quarter Left half of the moon appears illuminated Right half appears dark Moon will slowly disappear until the new moon.

14. Third Quarter

16. Waxing Moon is getting larger or growing Happens from new moon to full moon

17. Waning Moon is getting smaller or disappearing Happens from Full Moon to New Moon

18. Other Moon Phases CrescentGibbous

19. Crescent Moon Time from new moon to first quarter and from last quarter new moon Waxing Crescent Moon Waning Crescent Moon

20. Gibbous Moon Time from first quarter to full moon and time from full moon to last quarter Waxing Gibbous Waning Gibbous

22. Waxing or Waning???

24. What Phase is it in? First/Last quarter? New Moon? Full Moon? Crescent?Gibbous?

40. Eclipse Education

41. Solar Eclipse

42. Lunar Eclipse

43. Eclipses Happen when Sun, Earth, and Moon are in a perfect line. Shadow of either Earth or Moon are cast on the other. 2 Types: –1. Solar –2. Lunar

44. Solar Eclipse Sun, Moon, and Earth are in a perfectly straight line. Moon’s shadow is cast upon Earth in a specific spot Possible only twice a year Partial or total depending on location New Moon

46. Eclipse Terms Path of Totality: Path of the moon’s shadow during an eclipse. (200miles) Umbra: The moon’s complete shadow. (total eclipse) Penumbra: Moon’s partial shadow. (partial eclipse)

48. Eclipse Question??? Why don’t we get a solar eclipse every month? Answer: The moon’s orbit is tilted 5 degrees. So only twice a year are the sun, moon, and earth in correct position.

50. Warm Up Questions??? 1. What phase is the moon in at a 90 degree angle from the sun? 2. Why don’t we get a solar eclipse each month? 3. What's the difference between the Umbra and Penumbra? 4. How many times a year are solar eclipses possible?

51. Lunar Eclipse Sun, Earth, and Moon are in a straight line. Earth’s shadow covers the moon Visible to the whole dark side of the planet 3 Types: – –1. Penumbral – –2. Partial – –3. Total

53. Penumbral Lunar Eclipse Moon passes through Earth’s penumbral shadow Hard to observe

54. Partial Lunar Eclipse Part of the moon passes through the Earth’s umbra shadow.

55. Total Lunar Eclipse Entire moon passes through Earth’s Umbra Moon appears red No blue light allowed

56. Closing Questions??? 1. What type of eclipse is more common? Why? 2. What’s the difference between the umbra and penumbra? 3. Describe the alignment of earth, moon, and sun during each type of eclipse. 4. Why don’t we have an eclipse each month? 5. What are the three types of lunar eclipses?
