Title: Relationship Between the Earth, Moon and Sun


1
Relationship Between the Earth, Moon and Sun


2
THINK PAIR - SHARE
  • What is the difference between
  • rotation and revolution?
  • Think to yourself and discuss your thoughts with
    a partner.

3
Lets compare
Revolution
4
Engage Darkness at Night
  • Read the following scenario and choose which
    friend you agree with. Be prepared to discuss
    your answer.

5
Night and Day
  • The sun appears to move across the sky but it is
    actually the EARTH thats turning.
  • The Earth ROTATES on its axis once every 24 hours
    causing day/night.

The Moon also rotates on its axis.
Answer Talia
6
Months
  • The moon travels around the Earth and takes less
    than a month to complete its orbit.
  • The moon REVOLVES around the Earth.

7
Years
  • The Earth travels around the Sun and takes 365.25
    days to complete its orbit.
  • The Earth REVOLVES around the Sun.

8
Think Pair Share
  • Why do we have seasons on Earth?
  • Think to yourself and discuss your thoughts with
    a partner.

9
What Causes Seasons?
  • The Earth's seasons are not caused by the
    differences in the distance from the Sun
    throughout the year (these differences are
    extremely small).
  • The seasons are the result of the tilt of the
    Earth's axis. Since the axis is tilted, different
    parts of the globe are oriented (pointed) towards
    the Sun at different times of the year.

10
What causes seasons?
  • Summer is warmer than winter (in each hemisphere)
    because the Sun's rays hit the Earth at a more
    direct angle and the days are much longer than
    the nights during the summer.
  • During the winter, the Sun's rays hit the Earth
    at an extreme angle, and the days are very short.

11
Directness of the Suns Rays
12
Seasons
Label the Seasons diagram in your foldable with
the correct seasons for both the Northern and
Southern Hemispheres.
13
Solstices
  • Solstices occur when Earth's axis is pointed
    directly toward our Sun. This happens twice a
    year during Earth's orbit.
  • Summer Solstice the first day of summer
  • Occurs near June 21 in the Northern Hemisphere
  • the north pole is tilted toward the Sun
  • the longest day of the year
  • Winter Solstice the first day of winter
  • Occurs near December 21 in the Northern
    Hemisphere
  • the north pole is tilted away from the Sun
  • the shortest day of the year
  • When are the winter and summer solstices in the
    Southern Hemisphere?

14
Equinoxes
  • Equinoxes are days in which Earths axis is not
    pointed toward our Sun. Every location on our
    Earth (except the extreme poles) experiences
    12 hours of daylight and 12 hours of darkness.
  • Vernal Equinox the first day of spring
  • Occurs March 21 or 22 in the Northern Hemisphere
  • Autumnal Equinox the first day of fall
  • Occurs on September 22 or 23 in the Northern
    Hemisphere
  • When are the vernal and autumnal equinoxes in the
    Southern Hemisphere?

15
Going Through a Phase
  • Complete the Moon Phase probe.
  • Read the thoughts of other students and explain
    which student you agree with on the paper
    provided.
  • 5 minutes

16
Four Corners
Around the room are the names of the students
whose ideas were on the probe Going Through a
Phase Move to the student you agreed with and
create a poster that describes your groups
thinking. As we begin to share thoughts, you
will be given an opportunity to share.
17
Sofias Right!!!!!!!
  • Heres why!
  • Moon Phases


18
Moon Phases
  • The revolution of the Moon around the Earth
    makes the Moon appear as if it is changing shape
    in the sky.
  • From Earth, we see the Moon grow from a thin
    crescent to a full disk or full moon and then
    shrink back to a thin crescent again before
    vanishing for a few days.
  • Moon phases are grouped by either waning or
    waxing.

19
New Moon - is not visible from Earth. The moon is
between the Sun and the Earth. The dark side is
facing us.
Waxing Crescent - waxing means that the bright
side is increasing. The right side is the bright
side.
  • First Quarter - the entire right side of the moon
    is illuminated. The moon looks like a half
    circle.

Waxing Gibbous - gibbous means that more than one
half is visible, but it is not quite full
20
  • Full Moon - the moon is full and bright. It
    looks like a large circle. The illuminated side
    is facing us.

Waning Gibbous - the moon appears more than half
but not quite full. Waning means that the
illuminated side is decreasing. The left side is
the bright side.
Last Quarter - left half of the moon is
illuminated. The illuminated side is decreasing.
Waning Crescent - less than one half of the moon
is illuminated. The amount of light continues to
decrease.
21
How do I tell if a moon is WANING or
WAXING? Complete the Venn diagram.

23
Card Sort Moon Phases
  • With a partner, grab a set of Moon Phases cards
    and match the picture, name and description of
    the phase.
  • Raise your hand for the teacher to check your
    work when you are done.

24
Reinforce Label the Moon Phases
25
Tides
  • Tides are a change in the ocean water level,
    typically reaching a high and low level twice a
    day.
  • Tides result from the pull of gravity on Earths
    waters by the moon, sun and Earth itself.
  • The result of this tidal pull is a bulge in the
    ocean water almost inline with the position of
    the moon one bulge toward the moon and one on
    the opposite side of the earth, away from the
    moon.

26
Tides
27
Spring Tide
  • When the Earth, Moon and Sun are in line, the
    combined effect of the Moon's and Sun's pull on
    Earth's water is at its greatest, resulting in
    the greatest ranges between high and low tide.
    This called a "spring" tide (from the water
    springing or rising up).

28
Neap Tide
  • When the earth, moon and sun are at right angles
    to each other, the pull of the moon and the pull
    of the sun partially cancel each other out. The
    resulting tide, called a "neap" tide, has the
    smallest range between high and low tide.
