  1. The Moon Alabama Course of Study # 9 Describe the appearance and movement of Earth and its moon. Identifying lunar and solar eclipses. Identifying the waxing and waning of the moon in the night sky.

  2. The moon is Earth’s only natural satellite. http://en.wikipedia.org/wiki/Moon

  3. The gravitational attraction generated by the rotation of the Moon and Earth around a common point is largely responsible for the tides on Earth. http://www2.jpl.nasa.gov/galileo/images/earthmo2.gif

  4. The Moon is the only celestial body to which humans have traveled and upon which humans have landed. http://nssdc.gsfc.nasa.gov/imgcat/thumbnail_pages/moon_thumbnails.html

  5. The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned towards the Earth at all times. The far side of the Moon The near side of the Moon http://en.wikipedia.org/wiki/Moon

  6. The side of the Moon that faces Earth is called the near side, and the opposite side is the far side. The far side should not be confused with the dark side, which is the hemisphere that is not being illuminated by the Sun at a given moment. First images of the far side of the Moon taken from Luna 3 http://en.wikipedia.org/wiki/Moon

  7. The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7hours 43 minutes. http://www.google.com/search?sourceid=navclient&aq=t&ie=UTF-8&rls=DIUS,DIUS:2006-22,DIUS:en&q=phases+of+moon

  8. http://www.google.com/search?sourceid=navclient&aq=t&ie=UTF-8&rls=DIUS,DIUS:2006-22,DIUS:en&q=phases+of+moonhttp://www.google.com/search?sourceid=navclient&aq=t&ie=UTF-8&rls=DIUS,DIUS:2006-22,DIUS:en&q=phases+of+moon In between, the moon’s illuminated surface appears to grow (wax) to full, then to decrease (wanes) to the next new moon.

  9. The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth’s shadow). When the sun and moon are on opposite sides of the earth, the moon appears “full” to us, a bright, round disk. http://spaceplace.nasa.gov/en/educators/images/moon/Moon_phases_all_L.jpg

  10. When the moon is between the earth and the sun, it appears dark, a “new” moon. New Moon - The Moon's unilluminated side is facing the Earth. The Moon is not visible (except during a solar eclipse). http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  11. Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  12. First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  13. Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  14. Full Moon - The Moon's illuminated side is facing the Earth. The Moon appears to be completely illuminated by direct sunlight. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  15. Waning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  16. Last Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  17. Waning Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm

  18. Eclipses can occur only when the Sun, Earth, and Moon are all in a straight line. Because the Moon’s orbit around the Earth is inclined by about 5 degrees with respect to the orbit of the Earth around the Sun, eclipses do not occur at every full and new moon. http://en.wikipedia.org/wiki/Lunar_eclipse

  19. Solar eclipses can occur near a new moon, when the Moon is between the Sun and Earth. http://en.wikipedia.org/wiki/Solar_eclipse

  20. Lunar eclipses can occur near a full moon, when the Earth is between the Sun and Moon. http://en.wikipedia.org/wiki/Lunar_eclipse
