Lunar Cycle ppt cscope

  1. 1. Lunar CycleGoal: Identify the phases of the Moon, and relate the phases to eclipses.
  2. 2. Memory Devices: White on the right, growing bright! White on the left, losing light!
  3. 3. Memory Devices: Wax on – increasing light! ◦ Just as a candle wick is dipped in wax and the candle wax increases the size of the candle. Wane off – decreasing light! Gibbous – bulge
  4. 4. Memory Devices: New Moon = Near the Sun Full Moon = Far from Sun Remember, YOU are on the EARTH looking at the Moon.
  5. 5. The new moon phase occurs when the Moon is between the Sun and the Earth. When this occurs, there is a possibility of having a solar eclipse. Solar eclipses do not happen each month because the orbit of the Moon is 10o off from the orbit of the Earth.New Moon
  6. 6. The Moon revolves around the Earth. Waxing means to increase in size. This refers to the lit portion of the Moon. Crescent refers to the shape.Waxing Crescent
  7. 7. When the Moon has gone one fourth of the way around the Earth, it is called the first quarter. From our point of view, the right half of the Moon is lit.First Quarter
  8. 8. The gibbous phase looks like a fat football. The word gibbous means bulging. During the waxing gibbous phase, the lit side of the Moon continues to grow in size.Waxing Gibbous
  9. 9. During the full moon, we see the light reflecting from the entire surface of the Mmoon facing the Earth. During this phase, it is possible to have a lunar eclipse.Full Moon
  10. 10. Waxing means to decrease in size. During the waning phase of the Moon, the lit portion decreases in size. The waning gibbous occurs after the full moon.Waning Gibbous
  11. 11. The third quarter has the lit side on the left. The Moon is three fourths of the way around its orbit.Third Quarter
  12. 12. The waning crescent gets smaller and smaller, until the Moon completes its orbit and begins a new cycle with another new moon.Waning Crescent
  13. 13. The Moon moves directly between the Sun and Earth. The Moon casts a shadow on the Earth; only occurs with a new moon. This does not occur with every new moon due to the moon being 10o off from the orbit of the Earth.Solar Eclipse
  14. 14. The Earth, Sun, and Moon are directly lined up in the center. The Earth casts a shadow on the Moon; only occurs with a full moon. This does not occur with every full moon due to the Moon being 10o off from the orbit of the Earth.Lunar Eclipse
  15. 15. Memory Devices: White on the right, growing bright! White on the left, losing light!
  16. 16. Memory Devices: Wax on – increasing light! ◦ Just as a candle wick is dipped in wax and the candle wax increases the size of the candle. Wane off – decreasing light! Gibbous – bulge
  17. 17. Memory Devices: New Moon = Near the Sun Full Moon = Far from Sun Remember, YOU are on the EARTH looking at the Moon.
  18. 18. First QuarterReview:What phase is this? Be prepared toJustify your answer.
  19. 19. New Moon Waxing CrescentWhat phase?What phase would be next?
  20. 20. Waning Gibbous Third QuarterWhat phase?What phase would be next?
  21. 21. Full Moon Waning GibbousWhat phase?What phase would be next?
  22. 22. Waxing Crescent First QuarterWhat phase?What phase would be next?
  23. 23. Lunar EclipseWhat type of eclipse could occurduring this phase?
  24. 24. First Quarter Waxing GibbousWhat phase?What phase would be next?
  25. 25. Waning Crescent New MoonWhat phase?What phase would be next?
  26. 26. What is different from our view on Earth?A View From Outer Space
  27. 27. • Would you still be able to label the phases without seeing them? • This type of question and graphic is quite common on assessments.A View From Outer Space
  28. 28. Moon Phase Graphic Organizer
