THE UNIVERSE
• The Universe is everything that exists. It is all the space and
everything that is in it. The edge of the Universe is about 14
thousand million light years away. It has taken light this many
years to reach the Earth.
• The Universe consists of galaxies, which are huge clusters of
billions of stars, planets, moons, rocks, dust and gases, held
together by gravity. Galaxies are the building blocks of the
Universe.

THE CENTRE OF THE UNIVERSE
I don’t
think so!
Copernicus
Hundreds of years ago,
people thought that the
Earth was the centre of
the Universe and that
the Sun and planets
rotated around the Earth!
Nicholas Copernicus, was a Polish astronomer
who lived in the 17th century, He studied the stars
and discovered that the Earth and the other
planets actually rotate around the Sun.

STARS
• All the stars in the night sky are
gigantic nuclear furnaces like
our Sun. They convert hydrogen
into helium and release huge
amounts of energy (this is
known as nuclear fusion).
• The closest star to Earth is the
Sun.

Lighter stars, like our Sun, follow this life cycle:
Nebula
collapses due
to its own
gravity.
Forms a
star like
our Sun. Expands
to form a
red giant.
Outer layers of star drift
away to leave a dense
white dwarf.
Very small nebulae
form failed stars.
SMALL STARS

Stars that are much heavier than our Sun follow this life cycle:
Larger nebula
collapses due to its
own gravity.
Forms a star
more massive
than our Sun.
Expands
to form a
massive red
giant.
Red giant
collapses violently
in a supernova
explosion. Very dense neutron
star formed.
MASSIVE STARS

The end of the life cycle of really massive stars is different to
that of massive stars.
After a really massive red giant collapses in a supernova
explosion, it leaves a star so dense that not even light can
escape its gravitational pull. This is called a black hole!
Some scientists believe
that there are black
holes at the centre of
galaxies.
REALLY MASSIVE STARS
![Page 11: EARTH, MOON & SUNmswrsc.weebly.com/.../1/1/4/8/11488051/earth_moon__sun.pdfThe Sun is about 400 times wider than the Moon but is 400 times further away!

This causes the
‘nebula’ to collapse.
Gravity causes a dust and
gas cloud to condense
into a smaller volume.
As the nebula collapses,
temperatures and pressures
inside the nebula increase.
When the temperature and
pressure are great enough
nuclear fusion starts.
Eventually gravity and
the outward pressure
of escaping energy is
balanced. At this stage,
it is called a star.
What is the correct order for these sentences about how a star is formed?

shapes in the sky. Astronomers recognise 88 constellations
covering both the Northern & Southern Hemispheres.

own. It reflects the light of the
Sun or star.

The four inner planets are small, dense and mostly
made of rock.
The outer planets, apart from Pluto, are made of liquefied gases such as hydrogen,
carbon dioxide and ammonia.
The asteroids, between Mars and Jupiter, are pieces of
rock with diameters from a few km up to 1000 km.
Pluto, the outermost planet, is believed to be made of rock and
ice.

• We live at number 3. Our house has a big pool and a big grassy lawn, and we own one car. Our neighbours don’t have a pool or a lawn, in fact we don’t really have neighbours, the houses on both sides are empty. No-one else lives in any of the houses in our street, so I don’t have any friends to play with. At the beginning of the street is a huge shopping centre. If we didn’t have that near us we couldn’t live where we do because it’s too far to any other shops. Our street is so long I’ve never been down to the end of it, and Mum won’t let me go to the shopping centre because she says it’s dangerous. I really like where we live at number 3 though, it’s the only home we’ve got…

• How many houses are there in my street?
• Which house has the most cars?
• Do any other houses have a pool or a lawn?
• Which is the biggest house in the street?
• What does the shopping centre represent?
• Why does no one else live in the street?
• What features of the solar system can we include in our street – how?

Your Task:
• Create an analogy of the solar system.
• For example: A street where the houses are the planets, cars are moons, etc ..
Contents:
• A description and picture of each ‘planet’:
• Size
• What its made of
• Colour
• Atmosphere
• An indication of how many moons it has
• Any other interesting features

THE SEASONS
• The seasons are the result of the tilt of the Earth's axis. The
Earth's axis is tilted an angle of 23.45°. This tilting is what gives
us the four seasons of the year - spring, summer, autumn and
winter. Since the axis is tilted, different parts of the globe are
oriented towards the Sun at different times of the year.
• Summer is warmer than winter because the Sun's rays hit the
Earth at a more direct angle during summer than during winter
and also because 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. These
effects are due to the tilt of the Earth's axis.

The Moon is the Earth’s only natural satellite.
The Sun is about 400 times wider than the Moon but is 400 times further away!
The Moon rises and sets just like the Sun. It rises about 50 minutes later each day. The Moon is in the
sky during the day as well as at night, but it is harder to see then.

THE TIDES
• The oceans rise up and fall back again twice everyday, due to the Moon’s
gravitational pull.
• These water movements are called the tides. As the Earth rotates it
experiences two cycles of high and low tides, roughly thirteen hours apart.
• High tides: the Moon’s gravity causes a bulge of water on the side of the
Earth closest to the Moon and another on the opposite side of the Earth.
• Low tides: in between bulges there is less water and the tides are low.
• Spring tides: the extra large tides that occur twice a month when the Sun,
Moon and Earth are lined up. The pull on the oceans due to gravity is
stronger then.
• Neap tides: are small, weak tides that occur twice a month when the Sun,
Moon and Earth are at right angles to one another. The Sun and Moon’s
gravity cancel each other out so the pull on the oceans is weaker.

A solar eclipse happens when the Moon passes between the
Sun and the Earth. This casts a shadow over the Earth.
The last solar eclipse over the Australia was in 2002. Solar
eclipses do not occur very often. Our next one is in November
this year.
A lunar eclipse happens when the Earth passes between the
Sun and the Moon. This casts a shadow over the Moon.
Lunar eclipses happen in most years.

Where must the Moon be for a solar eclipse to take place? During a solar eclipse the Moon moves directly between the Sun and the Earth.
WHAT HAPPENS DURING A SOLAR ECLIPSE?
During a solar eclipse the Moon blocks the Sun’s rays from reaching part of
the Earth.
