like?

Astronaut
An astronaut is a person
who travels in space to
explore.
 On July 2, 1969,Neil
Armstrong and Edwin
Aldrin were the first two
people to walk on the
moon.
 Scientists have studied
rocks and photographs
these astronauts brought
back.

Stars


A star is a big ball of hot
gases which give off light.
How bright a star is
depends on . . .
- the size of the star
- how hot the star is
- how close the star is to
Earth
Why do people in the cities see fewer
stars than people who live in the country?

There are too many lights in the city. These
lights prevent people from seeing thousands
of stars each night.
Constellations

A constellation is a
group of stars that
form a star picture.
Sun






The sun is the closest star
to Earth.
The sun is a big ball of hot
gases.
The sun gives off two kinds of
energy: light and heat. This is
called solar energy.
The sun never moves.
All nine planets orbit, or move, around the sun.
The sun is so large that more than a million
Earths could fit inside it.
With out the sun, there would
be no life. Why?


Plants use the sun’s light to make food.
Animals and people use the sun’s light to see in the
daytime.
Plants and animals need light and heat to live and
grow.
The sun’s heat warms water, land, and air.
The sun’s heat warms all living things on Earth.
All the other planets go around the sun, too, but
Earth is the only planet where we can live. The sun
gives us just the right amount of heat and light.
Planet
A planet is a large ball of rock or gas that
follows a path round the sun.
 There are nine planets.

Sun  Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus, Neptune, Pluto
( My Very Eager Mother Just Served Us Nine Pizzas! )
The solar system includes the sun
and nine planets.
Earth





Earth is the planet that we live on. It is the 3rd
planet from the sun.
It is called a “Rocky Planet,” because it is made
of rocks.
Sometimes Earth is called the “Water Planet,”
because it is the only planet with the water we
need to live.
Earth orbits, or circles, the sun in 365 days, or
one year.
While it is orbiting the sun, it also spins like a
top! It spins 1 time in 24 hours, and that is why
Earth’s day lasts for 24 hours.
Earth is the only planet where plants and
animals live
Earth has day and night.



Rotation is when something
spins round in round.
It takes about 24 hours for
the Earth to rotate, or spin.
This is one full day.
This rotation causes the Earth
to have day and night.

Seasons




A season is a time of year that has a certain kind of
weather.
- winter, spring, summer, and fall (autumn)
Earth follows a path around the sun. This path is
called an orbit.
As the earth moves around the sun, Earth has
different seasons.
The sun shines on
different parts of the
Earth at different
times which cause
the seasons.
Revolution
Remember that the Earth is tilted all the time
that it is moving around the Sun.
 It takes the Earth one year to move around
the sun. This is called a revolution. It follows
an orbit, or path.

The Moon





The moon is the largest
object you can see in the
night sky.
The Earth has one moon. The moon travels
around the Earth. It takes the moon about 4
weeks, one month, to travel around the Earth.
A crater is a hole, valley, or indentation on a planet
or moon made by a large rock.
There is no life on the moon because there is no
air.
Moonlight is the light of the moon. This light
comes from the sun. Which part of the moon is
lighted by the sun?
- The part of the moon that is facing the sun.
Phases of the Moon
We have all noticed
that the Moon looks
different from night to
night. Sometimes it is
in a different position
in the sky or has a
different shape or
phase.
Congratulations!
You have learned about the solar system.
 Can you name the nine planets, in order?
