Unit 11 – Science and Humanity
Describe long-term changes that have occurred in our universe
to our solar system and earth
By the end of this lesson
we should be able to:
• State the components of
the solar system (C)
• Describe the difference
between Comets and
meteors.(C)
• Explain early thoughts
about the solar system (C)
Success Criteria:
• I have drawn a diagram to
show the parts of the
solar system
• I have described the
structure and formation
of comets and meteors
• I have explained how
Copernicus dispelled may
peoples theories
Unit 11 – Science and Humanity
Starter
• Do you know the order of the solar
system???
• What method do you use to
remember this???
Unit 11 – Science and Humanity
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!
I don’t
think so!
Copernicus
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.

A01 Describe long-term changes that have occurred in our universe to
our solar system and earth
Describe the early thoughts about the center of the
universe?
Unit 11 – Science and Humanity
Most of the planets travel around
the Sun in near-circular orbits.
Comets also travel around the
Sun but in very elliptical orbits.
For most of its orbit, a comet is
a long way from the Sun.
The head of the comet is a lump
of ice and dust a few kilometres
across.
The tail only appears when the
comet is near the Sun. It consist
of gas and dust which are
released by the heat of the Sun.
Comets
Unit 11 – Science and Humanity
As the Earth moves
Meteors and meteorites
through space, it collides
with lumps of material
which burn up in the
atmosphere.
These are called meteors
and can be seen as streaks
of light in the night sky.
A large meteor may not burn
up completely and hits the
Earth with a lot of energy.
This is called a meteorite.
A meteorite impact is one
theory to explain why the
dinosaurs became extinct.
