1 Phases of the Moon

2 The Moon The moon is the Earth’s only natural satellite. It is the second brightest object in the sky after the sun. It is reflection of sunlight that allows us to see the moon so brightly (Without the sun’s light we would not see the moon at all). Only half of the moon can be lit at one time, resulting in ½ of the moon being in sunlight while the other ½ is in darkness.

4 Orbit Around the Earth The moon orbits around the Earth once every 29.5 days. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon's phases.Moon The rotation of the moon around the Earth causes the moon to appear to change shape in the sky.

5 Phases of the Moon There are 8 phases of the moon that repeat every rotation of the moon around the Earth.

6 Why does the Moon Change Shape? http://www.youtube.com/watch?v=F hokvJZFURghttp://www.youtube.com/watch?v=F hokvJZFURg

7 Moon Phase Terminology Waxing: The part of the moon that is in sunlight is getting bigger (lit part is growing) Waning: The part of the moon that is in sunlight is getting smaller (lit part is shrinking) Crescent: Less than half of the moon is illuminated. Gibbous: More than half the moon is illuminated.

9 Lunar Phases New Moon (Phase 1): Beginning of the lunar cycle. No part of the moon is illuminated (cannot see moon).

10 Waxing Crescent (Phase 2): After the new moon a thin crescent shape that gradually gets larger is illuminated.

11 First Quarter (Phase 3): The moon is a quarter of the way through it’s orbit. It appears that half of the moon is illuminated.

12 Waxing Gibbous (Phase 4): More than half of the moon is illuminated.

13 Full Moon (Phase 5): Half of the moon is illuminated. Remember, we see it as a full moon, but only half of the moon is in sunlight!

14 Waning Gibbous (Phase 6): The illuminated part of the moon is getting smaller, but still over half is illuminated.

15 Third Quarter (Phase 7): The moon is 3 quarters through the rotation. Half of the moon is illuminated.

16 Waning Crescent (Phase 8): The illuminated part of the moon is getting smaller. The only visible part is a crescent shape.

18 Making a Moon Calendar The most recent New Moon was on Wednesday May 28 th 2014. On the blank Calendar begin numbering your Calendar for June (start with Wednesday May 28 th) From your pictures, cut out a new moon and paste it on the May 28 th square. Continue to paste on the pictures of the phases of the moon in the correct order until you have successfully complete one rotation of the Earth.
