The phases of the moon. Facts about the moon.

1. The Moon and Its Phases
Mrs. Burch

2. Goal: I will understand why the moon
looks different during different times
of the month.
Bonus: I will learn interesting facts
about the moon.

3. Why does the moon look different at
different times of the month?

4. http://mysteryscience.com/
Watch this video lesson on the
phases of the moon.

5. Where does the concept for a
month come from?

6. Can you ever see the moon during the
day?

7. Yes

8. During what phase is the moon ONLY
visible at night and not in the daytime
at all?

9. A New Moon

10. The moon is a natural satellite of our
earth.

11. The name “moon” comes from the
German word for moon, which is
“mond”. “Mond” derived from the
word for month.
moon = month

12. Watch this video of how the Earth and
Moon orbit the Sun together.

13. The Romans, who spoke Latin, named
the moon “Luna”, the Roman Goddess
of the Moon.

14. So, things relating to the moon are
referred to as “lunar”, after the
Latin name for the moon.
Lunar craters

15. How did the Moon get there?

16. Watch this 8 ½ minute video on the
most popular theory of how the Moon
was formed:

17. The moon's surface is covered with
dead volcanoes, impact craters, and
lava flows.

18. Watch this 1 minute video on the
Moon’s volcanic eruptions:

19. The dark and large areas are called
maria, which is Latin for “seas”.

20. The maria are covered in hardened
lava that had seeped onto the surface
when the moon was young.

21. The singular form of “maria” is “mare”.
Apollo II landed in Mare Tranquillitatis.

24. The moon is about 27% smaller than
the earth. Below is a side-by-side
comparison.

25. The moon is about 238,900 miles from
the earth. Picture taken during Apollo 11 Mission.

26. If the Moon was a circle 2 centimeters
in diameter, the Earth would be 8
centimeters in diameter. The distance
to the Moon would be 60 times this
distance, or 8 cm x 60 = 480
centimeters (4.8 meters).

27. This shows the distance between the
earth and the moon to scale.

28. It took 3 days for the Apollo 11 to
reach the moon, traveling at 7 miles
per second. (25,200 mph)

32. Let’s look at some facts about the
Moon:

33. When sunlight hits the moon's surface,
the temperature can reach 253o F .
The "dark side of the moon" can have
temperatures dipping to minus 243o F .

34. The coldest place in our
solar system might be in
one of the moon’s
craters. Some of these
craters NEVER get
sunlight. They are in
constant shadow. New
surveys determined that
these might be as cold
as -397 degrees
Fahrenheit!

35. What is the “dark side of the
moon”?

36. https://youtu.be/6jUpX7J7ySo
The dark side of the moon is the side
that we never see from Earth.
Watch this video for an explanation.

37. Far side of the
moon
Near side (the side
we see from Earth)

38. The moon has an iron-rich core. The temperature in
the core is probably about 2,500 F .

39. The core heats an inner layer of molten mantle, but
it's not hot enough to warm the surface of the moon.

40. The moon constantly orbits, or
revolves, around the Earth.

41. The moon revolves around the earth
in the same direction as earth
rotates.

42. Did you know...the moon’s gravity
is strong enough to pull on our
ocean, creating tides.

44. Let’s look at the Moon’s phases:

46. Activity:
1. Imagine that the back wall is the
Sun.
2. Your head is the Earth.
3. Make a fist to represent the Moon.
Then….

47. a. Demonstrate the location of the
New Moon.

48. b. Demonstrate the location of the
Full Moon.

49. c. Demonstrate the location of the
1st Quarter Moon.
What does it look like from Earth’s
perspective? Which side is lit?

50. d. Demonstrate the location of the
3rd Quarter Moon.
What does it look like from Earth’s
perspective? Which side is lit?

51. e. Demonstrate the location of the
waxing crescent Moon. Which side
is lit?

52. f. Demonstrate the location of the
waxing gibbous Moon. Which side
is lit?

53. g. Demonstrate the location of the
waning gibbous Moon. Which side
is lit?

54. h. Demonstrate the location of the
waning crescent Moon. Which side
is lit?

55. Notice the location of the Full
Moon.

57. How is it possible for us to see the Full Moon
when it’s behind the Earth? Why doesn’t the
Earth block the Moon from getting sunlight?

58. The Moon's orbit actually dips a little
bit above and below an imaginary line
drawn between Earth and the Sun.
That is why Earth seldom blocks the
Sunlight from reflecting off the full
Moon. Once in a while, though, Earth
does get directly in the way, and we
have the exciting event called a lunar
eclipse.

92. How long does it take for the Moon to
orbit Earth one time?

93. About 28 days (it’s really 27.3 days).

94. Determine the Moon’s location week
by week:

95. The New Moon is the start of the lunar
cycle.

104. How many times does the Moon orbit
around the Earth in 1 year?

105. 12 times

106. 12 times. That’s why there are 12 months in
a year.

107. If the New Moon is on the 5th, what is the
best guess for when the Full Moon will be?
New

108. A good guess would be the 19th. In actuality,
it will be on the 20th.

Full

109. If the New Moon is on the 5th, what is the best
guess for when the next New Moon will be?
New

110. The best guess would be Feb. 2nd, but in actuality,
it will be on Feb. 4th.
New
New

111. The reason our good guesses are not
perfect is because the Moon takes
27.3 days to orbit Earth, but the lunar
phase cycle (from new Moon to new
Moon) is 29.5 days. The Moon spends
the extra 2.2 days "catching up"
because Earth travels about 45 million
miles around the Sun during the time
the Moon completes one orbit around
Earth.

around the Earth.
