									                             Phases of the Moon
When we gaze up into the
night sky, what is it that
we see?

Sometimes we see a Full
Moon. On other occasions
we see half of the Moon,
and on others we see less
than half or more than
half. Then there are times
when we don't see it at all.

What we're witnessing are
the Phases of the Moon.
                       Phases of the Moon
Our nearest
neighbor in space,
the Moon is a
natural satellite of
the Earth.

Great plains
stretch over the
moon's surface,
dotted with huge
mountains and
scarred by
numerous craters.
                   Phases of the Moon
As the Moon
orbits the Earth
it goes through
a sequence of
phases as the
proportion of
the visible
                           Phases of the Moon
The revolution of the
Moon around the
Earth makes the Moon

changing shape in the
The Moon doesn't
generate any light
itself; it just reflects
the light of the Sun.

    Day 1
  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

     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.

Planting by the Moon

Many people plant
gardens by the
phases of the moon.

It was so well
established in the
first century AD that
it became part of the
“natural history” that
Pliny the Elder wrote
                      Phases of the Moon

People believe that
planting by the
phases of the
Moon makes seeds
germinate faster.
The believe that
plants are hardier
and more disease-
resistant and that
they blossom
sooner and bear
more fruit.
