Travel along and we will find out where we live
in space and what we can see in space.
3
Do you know what a solar system is? Do you
know what is in our solar system?
4
Our solar system is made up of an enormous sun
and everything that travels around it.
5
We live on one of the nine planets in our
system. Other small bodies called asteroids and
comets can be found in our system also.
6
If we were to put the planets in order , from
the one closest to the sun, they would be
Mercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, Neptune, and Pluto.
7
What do you know about how our planet, Earth,
moves in space?
8
Earth is the third planet. We call Earth our
home planet. It is the shape of a sphere.
9
It has oceans full of water, green forests,
animals, plants, and breathable air. It is a
unique planet. From space, the Earth looks like
a beautiful blue-green marble, with white
swirling clouds.

• Sunlight comes from the sun to the Earth. The
  sunlight that warms our faces right now left the
  sun over eight minutes ago. The sun warms the
  Earth.

11
What causes daytime and night time on the
Earth?What causes the changing of our seasons?
12
The Earth whizzes along spinning in space at
67,000 miles an hour. We cant feel it spinning.
Yet is makes one complete turn every 24 hours.
13
This spinning around like a top is called
rotation. As it spins only one side faces the
sun. Day begins when our part of the world turns
to face the sun.
14
Night falls when our part of the Earth turns away
from the sun. The side facing away from the sun
has nighttime.
15
This rotation or spinning of Earth
causes day and night. The Earth rotates on its
axis. The axis is an imaginary line through its
center. It rotates once every 24 hours causing
day and night.www.enchantedlearning.com/subjects

16
Every day the Earth travels around the sun. The
Earth and the moon travel together in an orbit
around the sun once a year.
17
One revolution around the sun equals 365 days.
This revolution causes the changing of the
seasons.

When the Earth moves closer to the sun, summer
returns. When the Earth moves farther away from
the sun in its orbit, winter returns.

• What is the Earths natural satellite?
• What does it look like?

20
The moon is the Earths only natural satellite.

• The moon is a ball of rock that is dry and dusty.
  It has craters, valleys, mountains, and large
  patches called seas.

21
In 1969, the first man stepped onto the moon.
There is no wind or rain on the moon to wash the
footprints away.

• Where does the light shining from the moon come
  from?
• Why does it seem to change shapes in space?

23
The moon circles around the Earth about once
every 28 days. The moon does not spin like the
Earth. The moon only spins once a month on its
axis. The moon looks bright at night, but it does
not make its own light.

24
We see the moon because the sun shines on it.
The sunlight bounces off the moon and down toward
the Earth. We see reflected sunlight.
25

• As the moon travels around the Earth, we can see
  different amounts of the side lit by the sun.
  The moons appearance changes each day through
  the month depending on where the moon is in its
  orbit.

• These changes of how the moon looks from the
  Earth are called the moons phases. Sometimes
  the moon looks completely dark and seems to
  disappear. This is called a new moon. Sometimes
  the moon looks round. This is called a full moon.

28

• After the new moon, the moon appears to change.
  More and more of the moon starts to show. This
  is a crescent moon. When the moon is growing
  larger, we call this a waxing moon.

29

• It appears to grow larger until it is a round,
  full moon. Then the full moon appears to grow
  smaller. This is called the waning moon. When
  the moon goes from a new moon to a full moon, it
  has complete one orbit of cycle.

30

• A complete orbit of the moon around the Earth
  produces the moons phases that we see. This
  complete cycle of the moons phases takes 29.5
  days.

31

• Because of the moons orbit or cycle of 29.5
  days, moonrise can appear later each day. That
  is why we see sometimes see the moon in the sky
  at night and other times we see it during the day.

32
Learning about the Earth and the moon has made
all of you Space Kids. See if you can now answer
the following questions.
33
Do you know what a solar system is? Do you
know what is in our solar system?
34
What causes daytime and night time on the
Earth?What causes the changing of our seasons?
35

• What is the Earths natural satellite?
• What does it look like?

36

• Where does the light shining from the moon come
  from?
• Why does it seem to change shapes in space?
