What can we learn about the moon

2. Have you ever took a look at the
moon in the sky at night?

3. Well, some times I see it like this
It’s a little bit dark
And other times I see it like this
Now it’s shinny

4. So is the moon really shinny or not?
The moon is not shinny, it only appears shinny
to us because it reflects the sunlight.

5. The properties of the moon:
- Low let’s take a journey up to the moon &
take a closer look at it.
(1) Size
-First if we take a look from our space ship,
we’ll see that the moon is smaller than the earth

6. (2) The temperature
-During daytime: The temperature on
the moon is so hot that could boil
water.
-During night time: It’s so cold ,
colder than any place on earth.

7. (3) Rocks
- The rocks of the moon are similar
to the rocks of the earth.

8. (4) Air & Water
-There is no water on the moon at all.
-Also, there is no air on the surface of
the moon & that’s why astronauts
wear oxygen cylinders when they
travel to the moon.

9. (5) Surface
-The surface of the moon contain few tall
mountains and flat plains.
-Most of the surface is covered with
craters (hollow pit in the ground
caused by meteoroids)

10. - Every day the ocean’s water rises & fall again,
this is called: tides
The Earth’s tides
The Earth’s tides: The daily rise and fall of the
ocean’s surface.
High tide Low tide

11. What do you think cause the earth’s
tides?
The moon has gravity, it pulls the
earth slightly, on the side of the
earth that faces the moon, water
of the ocean bulges outwards
( High tide)
The moon pulls the earth more
than the sun, because it’s closer
to the earth.

12. There is something about the moon that
confuses me, some times it has different
shapes in the sky
No dear, the moon doesn’t have different
shapes, it just have different phases
Phases???? What does this word means?
Well, let’s learn all about this word
“phases”

13. The phases of the moon
Remember that: the moon is not shinny, but we only see it shinny
because it reflect the sunlight , this is why it appears to us lightened.

14. What is the lunar phases?
-The moon is a sphere “like a ball” that rotates around the
earth.
-It takes 29 days for the moon to make one complete rotation
around the moon.
-As the moon rotates around the earth, different parts of the
moon appears to us and it depends on the amount of the
part of the moon that is lit by the sun.
-These different parts are called: “Lunar phases”

15. What causes parts of the moon to
be lit up?
- The moon is illuminated because it reflects the
light from the sun. The part of the moon facing
the sun is lit up. The part facing away from the sun
is in darkness.

16. What causes the different phases
of the moon?
- The phases of the Moon depend on its position in
relation to the Sun and Earth. As the Moon makes
its way around the Earth, we see the bright parts
of the Moon's surface at different angles. These
are called "phases" of the Moon.

17. The Moon phases

18. Phase (1)
The New moon
-It occur when the moon is between the sun & the earth.
- The moon looks totally dark in this phase, because the
lit part of the moon
Is away from the sun & we can only see the dark side of
the sun.

19. Phase (2)
Waxing crescent
- As the moon start to move around the earth, a small part of
the moon
start to appear to us “on the earth”
-Now the moon is called: Waxing crescent
(Waxing = Appearing)
It looks like a
croissant

20. Phase (3)
First quarter
-As the moon move around the earth, a bigger part is
start
to appear now and we can see a bigger part of the
moon.
- Now the moon is called: “First quarter”
It looks like half an
orange

21. Phase (4)
Waxing Gibbous
-The moon continues to move around the earth,
so bigger part start to appear.
-Now the moon is called: “Waxing gibbous”

22. Phase (5)
Full Moon
-Now we can see the moon completely,
it’s totally shinny & very beautiful
-This phase of the moon is called: “Full moon”
It looks like a ball
or a sphere

23. Phase (6)
Waning Gibbous
-As the moon moves, it start to disappear once again,
and once more we start to see only a part of it.
- This phase now is called : “ Waning gibbous”
“Waning = Disappearing”

24. Phase (7)
Third quarter
-The moon again becomes half –shinny & half-dark ,
but this time the left side is the shinny side
- This phase is called: “ Third quarter”

25. Phase (8)
Waning crescent
-Now the moon is disappearing
& only a small part of it on the left side
is still shinning.
- This phase is called: “Waning crescent”
