2. What is a satellite?
A smaller object that revolves
around a larger object.

3. Jupiter’s satellite

4. Does Earth have a natural
satellite?

5. The moon is Earth’s
natural Satellite.

6. How was the moon formed?
•Theory 1 - When the earth was forming and still
fluid, a piece of the Earth separated because of
the centrifugal force of the Earth spinning.
•Theory 2 - A comet, asteroid or other space
matter got pulled into the gravitational pull of the
Earth and became our Moon.

8. Does the moon
produce its own
light like a star?
No, it reflects
light from the
sun.

9. As the moon orbits the
Earth, the light being
reflected from the moon
will change in appearance.

10. The Phases of
the moon are the
nightly changes in
the moon’s
appearance .

11. There are eight
main phases of
the moon.

12. The moon goes
through ALL of its
phases every 29 ½
days.

14. Waxing is a term
that is used when the
lighted area of the
moon appears to be
getting larger each
night.

16. Waning is the term
used when the
lighted area of the
moon appears to be
getting smaller each
night.

18. Gibbous is the term
used when more than
half of the moon is
reflecting light.

20. Crescent is the
term used when less
than half of the moon
is reflecting light.

22. Now draw
the moon
phases!

45. The Moon moves
directly between the
Sun and Earth. The
Moon casts a shadow
on the Earth; only
occurs with a new
moon.
This does not occur
with every new moon
due to the moon being
10o off from the orbit
of the Earth.
Solar Eclipse

46. The Earth, Sun, and
Moon are directly
lined up in the center.
The Earth casts a
shadow on the Moon;
only occurs with a full
moon.
This does not occur
with every full moon
due to the Moon
being 10o off from the
orbit of the Earth.
Lunar Eclipse

47. Memory Devices:
White on the right, growing
bright!
White on the left, losing
light!

48. Memory Devices:
• Wax on – increasing light!
– Just as a candle wick is dipped in wax
and the candle wax increases the size of
the candle.
• Wane off – decreasing light!
• Gibbous – bulge

49. Memory Devices:
New Moon = Near the Sun
Full Moon = Far from Sun
Remember, YOU are on the EARTH looking
at the Moon.

50. This concludes our
fieldtrip to the moon!
