Title: PHASES of THE MOON


1
PHASES of THE MOON
2
Pre-test
  • Why does the moon have phases?
  • How many phases are there?
  • How long does it take the moon to go through all
    the phases?
  • Name the phases in order and draw an example of
    each phase?

3
Why does the MOON have Phases?
  • As the moon circles the Earth, the shape of the
    moon appears to change this is because different
    amounts of the illuminated (or lit up) part of
    the moon are facing us.

4
How many Phases of the Moon are there to see?
  • There are 8 phases of the moon that you can see
    each month.

It takes our Moon about 29.5 days to completely
cycle through all eight phases.
5
Phase One NEW MOON
  • Can you see anything here?
  • Well believe it or not the moons here its just
    that the side of the moon facing the Earth is not
    lit up by the sun so you cant see it!

6
Phase Two Waxing Crescent
  • A small part (less than 1/2) of the moon is lit
    up at this point. The part that is lit up is
    slowly getting bigger

7
Phase Three First Quarter
  • One half of the moon is lit up by the sun at this
    point. The part that is lit up is slowly getting
    bigger.

8
Phase Four Waxing Gibbous
  • At this time over half of the moon is lit up.
    The part that is lit is slowly getting bigger.
    Waxing means to slowly get bigger.

9
Phase Five FULL MOON
  • The side of the moon that is lit up by the sun is
    facing the Earth. The entire moon is lit up at
    this point.

10
Phase Six Waning Gibbous
  • The moon is not quite lit up all the way by
    sunlight. The part of the moon that is lit is
    slowly getting smaller. Waning means to slowly
    get smaller.

11
Phase Seven Third Quarter Moon
  • Half of the moon is lit up by the sun.
  • The part that we can see lit up is slowly getting
    smaller.

12
Phase Eight Waning Crescent
  • A small part of the moon is lit up at this point.

13
Can you see all 8 Phases!
14
COOL MOON FACT
  • When two full moons occur in a single month, the
    second full moon is called a
  • BLUE MOON.
  • Hence the old saying,
  • Once in a Blue Moon

15
Lets Try to see ALL 8 Phases by Making a LUNAR
LOLLIPOP!
16
  • What you will need
  • A small styrofoam ball about 5cm (2 inches) in
    diameter (actually any small ball, like a golf
    ball, will work, it's just easier with a
    styrofoam ball)
  • A bright light like a lamp (with the lamp shade
    removed), overhead projector, or slide projector
    (with a clear slide, or no slide in it)
  • A pencil
  • A dark room

17
  • The idea
  • Your head will represent the Earth (the top of
    your head will be the North Pole, under your chin
    will be the South Pole, your nose will be on the
    Equator), the light will be the Sun, and the
    small ball will be the Moon. You are going to
    follow the Moon through one complete "orbit" to
    see how the patterns of light and dark change on
    the Moon.

18
  • What to do
  • Setup the light in a darkened room so the bulb is
    at about the height of your shoulders (actually,
    setup the light with the lights in the room on,
    then turn the room lights off when you are ready
    to begin the experiment).
  • Stand about 5 feet away from the light (so the
    light shines on you), face the light.
  • Stick the styrofoam ball on the end of the pencil
    (so it looks like a lollipop --- if
    you don't have a styrofoam ball, just hold the
    ball you do have between your index finger and
    thumb, start with it in your left hand, make sure
    your fingers don't block the ball or the light).

19
  • Hold the pencil with the ball on the end of it
    (or the ball between your index finger and thumb)
    out at arm's length in front of you.
  • Start with the Moon (ball) between you and the
    Sun (light), this represents New Moon, the whole
    Moon looks dark (and you probably will have
    trouble seeing it because of the light).
  • Then "orbit" the Moon (ball) to your left by
    turning your body while staying in the same spot.
    As you turn watch how the pattern of light and
    dark on the ball changes.
  • When you are turned so your right shoulder is
    closest to the light, half of the Moon will be
    lit up, this represents First Quarter.

20
  • When you are turned so your back is to the light
    (you may need to lift the ball up higher to get
    it out of the shadow of your head), you will be
    at Full Moon and the whole side of the ball you
    can see will be lit up.
  • Once you are at Full Moon, you may need to switch
    the ball to your other hand before continuing
    (so your hand doesn't block the light).

21
  • Keep turning to your left, once you reach the
    point where your left shoulder is closest to the
    light, you will be at Third Quarter and again
    only half of the Moon will be lit up (but this
    time the opposite half than what you saw at First
    Quarter will be lit).
  • Continuing to turn to the left, you will
    eventually return back to New Moon and can start
    the phases all over again.
  • It takes the moon about a month to go through one
    complete cycle of the phases.

Now Lets Play the MOON PHASE CARD GAME!
  • Heres how you play
  • Divide into groups of 4 to 6 players. Distribute
    16 index cards for each player. Color and label
    the eight phases of the Moon on their index
    cards, making two complete sets of Moon Phases.
    Then combine one set of Moon Phases from each of
    member of a group shuffle these and place them
    in the Moon Pond in the middle. Then have the
    students collect the second set to shuffle and
    deal to the players, with each player receiving
    eight cards.
  • The object of the game is to collect as many
    pairs of phases as possible until all cards are
    gone, or the allotted time has expired.
  • As in the card game Go Fish, each player in
    turn asks the student to their left for the cards
    they need to make pairs. If their neighbor does
    not have the requested card, they must go fish
    in the Moon Pond. As pairs are matched, they are
    placed in a pile to the side of the player. The
    Students should ask for Moon phases by name (Do
    you have a waning gibbous?)
  • When a child collects all 8 sets, they call out
    Month of Moons! and place them in the correct
    sequential order to win!
