Each “moonth” the moon changes
shape…watch !
Why does the moon change shape?
(an inquisitive student wants to know!)
 As the Moon circles the Earth,
the shape of the moon appears to
change; this is because different
amounts of the illuminated part of
the moon are facing us. The shape
varies from a full moon (when the
Earth is between the sun and the
moon) to a new moon (when the
moon is between the sun and the
Earth).
WHAT IS THE NEAR SIDE AND FAR
SIDE OF THE MOON?
 The same side of the moon always faces the Earth. The far side
of the moon was first observed by humans in 1959 when the
unmanned Soviet Luna 3 mission orbited the moon and
photographed it. Neil Armstrong and Buzz Aldrin (on NASA's
Apollo 11 mission, which also included Michael Collins) were
the first people to walk on the moon, on July 20, 1969.
If you were standing on the moon, the sky would always
appear dark, even during the daytime. Also, from any spot on
the moon (except on the far side of the moon where you cannot
see the Earth), the Earth would always be in the same place in
the sky; the phase of the Earth changes and the Earth rotates,
displaying various continents.
Moon Cycle

The phases of the moon change.
Definitions of the Phases
Crescent Moon - when we can see only a sliver of the moon's disk
(the side of the moon facing us) Full Moon - when the moon's disk
is light because the Earth is between the sun and the moon
Gibbous Moon - when we can see roughly three-quarters of the
moon's disk
Half Moon - (also called quarter moon) when we can see one half of
the moon's disk (this is one-quarter of the entire moon's surface)
New Moon - when the moon's disk is dark (and invisible to us)
because the moon is between the sun and the Earth Quarter Moon
- (also called half moon) when we can see one half of the moon's
disk (this is one-quarter of the entire moon's surface)
Waning Moon - when the moon seems to be getting smaller, going
from full to gibbous to half to crescent to new
Waxing Moon - when the moon seems to be getting bigger, going
from new to crescent to half to gibbous to full
CRESCENT MOON



A crescent moon is part way between a
half moon and a new moon, or between
a new moon and a half moon.
GIBBOUS MOON

A gibbous moon is between a full moon and
a half moon, or between a half moon and a
full moon.
HALF MOON

A half moon looks like half a circle. It is
sometimes called a quarter moon (this
Moon has completed one quarter of an
orbit around the Earth from either the
full or new position and one quarter of
the moon's surface is visible from
Earth).
NEW MOON

   The new moon is the phase of the moon
when the moon is not visible from Earth,
because the side of the moon that is facing
us is not being lit by the sun.
           ?
Moonrise from Earth

The moon rises and sets every day, appearing on the horizon just like the
sun. The time depends on the phase of the moon. It rises about 30 to 70
minutes later each day than the previous day, so the moon is out during
daytime as often is it's out at night. At the time of the new moon, the
moon rises at about the same time the sun rises, and it sets at about the
same time the sun sets.
   As the days go by (as it waxes to become a crescent moon, a half moon,
and a gibbous moon, on the way to a full moon), the moon rises during
daytime (after the sun rises), rising later each day, and it sets at nighttime,
setting later and later each night.
    At the full moon, the times of moonrise and moonset have advanced so
that the moon rises about the same time the sun sets, and the moon sets
at about the same time the sun rises.
   As the moon wanes (becoming a half moon and a crescent moon, on the
way to a new moon), the moon rises during the night, after sunset, rising
later each night. It then sets in the daytime, after the sun rises.
    Eventually, the moon rises so late at night that it's actually rising around
sunrise, and it's setting around sunset. That's when it's a new moon once
again.
