1 EQ: How do we explain the causes of the moon phases?

2 EQ: How do we explain the causes of the moon phases?
Half of the Moon is always lit by the sun. As the Moon orbits the Earth, we see different parts of the lighted area. However, we never see the far side of the Moon. EQ: How do we explain the causes of the moon phases?

3 EQ: How do we explain the causes of the moon phases?
The moon revolves or orbits the Earth once every 29 days. We always see the same side of the moon because the moon rotates and revolves at about the same speed

4 EQ: How do we explain the causes of the moon phases?
The revolution of the Moon around the Earth makes the Moon look as if it is changing shape in the sky.  EQ: How do we explain the causes of the moon phases?

5 EQ: How do we explain the causes of the moon phases?
This is caused by the different angles from which we see the lighted part of the Moon's surface.  These are called "phases" of the Moon.  EQ: How do we explain the causes of the moon phases?

6 EQ: How do we explain the causes of the moon phases?

7 EQ: How do we explain the causes of the moon phases?
The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days.  The phases always follow one another in the same order: New moon First quarter Third quarter Full moon EQ: How do we explain the causes of the moon phases?

8 EQ: How do we explain the causes of the moon phases?
New Moon The lighted side of the Moon faces away from the Earth.  This means that the Sun, Earth, and Moon are almost in a straight line, with the Moon in between the Sun and the Earth.  The Moon that we see looks very dark EQ: How do we explain the causes of the moon phases?

9 EQ: How do we explain the causes of the moon phases?
New Moon EQ: How do we explain the causes of the moon phases?

10 EQ: How do we explain the causes of the moon phases?
First Quarter Moon The right half of the Moon appears lighted and the left side of the Moon appears dark.  During the time between the New Moon and the First Quarter Moon, the part of the Moon that appears lighted gets larger and larger every day, and will continue to grow until the Full Moon. EQ: How do we explain the causes of the moon phases?

11 Why is this called a quarter moon when half the moon is lit?
We are seeing half of half of the Moon EQ: How do we explain the causes of the moon phases?

12 EQ: How do we explain the causes of the moon phases?
First Quarter Moon EQ: How do we explain the causes of the moon phases?

13 Third (Last) Quarter Moon
Sometimes called Third Quarter.  The left half of the Moon appears lighted, and the right side of the Moon appears dark.  During the time between the Full Moon and the Last Quarter Moon, the part of the Moon that appears lighted gets smaller and smaller every day. It will continue to shrink until the New Moon, when the cycle starts all over again. EQ: How do we explain the causes of the moon phases?

14 EQ: How do we explain the causes of the moon phases?
Third Quarter Moon EQ: How do we explain the causes of the moon phases?

15 EQ: How do we explain the causes of the moon phases?
Full Moon The lighted side of the Moon faces the Earth.  This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle.  The Moon that we see is very bright from the sunlight reflecting off it. EQ: How do we explain the causes of the moon phases?

16 EQ: How do we explain the causes of the moon phases?
Full Moon EQ: How do we explain the causes of the moon phases?

17 There are also four other phases of the Moon sometimes used.
EQ: How do we explain the causes of the moon phases?

18 Waxing Crescent Moon This Moon can be seen after the New Moon, but before the First Quarter Moon.  The crescent will grow larger and larger every day, until the Moon looks like the First Quarter Moon. ("Waxing" means increasing, or growing larger.) EQ: How do we explain the causes of the moon phases?

19 EQ: How do we explain the causes of the moon phases?
Waxing Crescent Moon EQ: How do we explain the causes of the moon phases?

20 EQ: How do we explain the causes of the moon phases?
Waxing Gibbous Moon This Moon can be seen after the First Quarter Moon, but before the Full Moon.  The amount of the Moon that we can see will grow larger and larger every day.  ("Waxing" means increasing, or growing larger.) EQ: How do we explain the causes of the moon phases?

21 EQ: How do we explain the causes of the moon phases?
Waxing Gibbous Moon EQ: How do we explain the causes of the moon phases?

22 EQ: How do we explain the causes of the moon phases?
Waning Gibbous Moon This Moon can be seen after the Full Moon, but before the Last Quarter Moon.  The amount of the Moon that we can see will grow smaller and smaller every day. ("Waning" means decreasing, or growing smaller.) EQ: How do we explain the causes of the moon phases?

23 EQ: How do we explain the causes of the moon phases?
Waning Gibbous Moon EQ: How do we explain the causes of the moon phases?

24 Waning Crescent Moon This Moon can be seen after the Last Quarter Moon and before the New Moon.  The crescent will grow smaller and smaller every day, until the Moon looks like the New Moon. ("Waning" means decreasing, or growing smaller.) EQ: How do we explain the causes of the moon phases?

25 EQ: How do we explain the causes of the moon phases?
Waning Crescent Moon EQ: How do we explain the causes of the moon phases?

26 EQ: How do we explain the causes of the moon phases?

27 EQ: How do we explain the causes of the moon phases?
What is a blue moon? When 2 full moons occur in the same month, the second full moon is called a blue moon This is very rare The moon itself is not really blue EQ: How do we explain the causes of the moon phases?

28 EQ: How do we explain the causes of the moon phases?
Waxing & Waning EQ: How do we explain the causes of the moon phases?

29 EQ: How do we explain the causes of the moon phases?

30 EQ: How do we explain the causes of the moon phases?
Moon Movie The movie is an animated GIF created by Antonio Cidadao from a sequence of still images taken during March and April 1998. Copyright Antonio Cidadao. EQ: How do we explain the causes of the moon phases?
