Matter is everything around you.
Matter is anything that has a mass and volume.
volume
Matter is anything made of atoms and molecules.
Scientists have identified three states of matter:
matter
•
•
•
solids
liquids
gases
We speak about different states of matter depending on the
physical state of molecules and atoms.
States of Matter can change
Elements and compounds can move from one physical state to
another and not change.
Oxygen (O2) as a gas still has the same properties as liquid
oxygen. The liquid state is colder and denser but the molecules
are still the same.
Water is another example.
The compound water is made up of two hydrogen (H) atoms and
one oxygen (O) atom.
It has the same molecular structure
whether it is a gas, liquid, or solid.
Although its physical state, it is to
say, its properties (density,
temperature, pressure …) may change,
its chemical state remains the same.
It is to say, the formula of water
remains the same.
If the formula of water were to
change, that would be a chemical
change.
If you added another oxygen atom, you would make hydrogen
peroxide (H2O2). Its molecules would not be water anymore.

Hypotheses on the Universe
Throughout history, there have been numerous hypotheses on
the structure of the universe, from ancient and non scientific
beliefs to the present one on an expanding universe.
Complete the following text using the right words.
PTOLOMEIC SYSTEM
Ptolemy worked from the data of past astrologers to map over
one thousand stars. He compiled a list of 48 constellations, and,
for the most part, described the longitude and latitude lines of
the earth. He was a believer that the earth was the centre of the
universe and worked to advance this theory. The Ptolemaic
system is explained why some planets seemed to move
backwards for periods of time in their orbit around earth. He
theorized that each planet also revolved in a smaller circle as
well as a larger one. This was called the "epicycle." This theory
would survive for 1400 years, until it was finally accepted that
the earth was itself another planet in orbit around the sun.
COPERNICAN SYSTEM
Nicolaus Copernicus (February 19, 1473 — May 24, 1543) was
the first astronomer to formulate a scientifically based
heliocentric cosmology that displaced the Earth from the center
of the universe. His publication of a scientific theory of
heliocentrism, demonstrating that the motions of celestial
objects can be explained without putting the Earth at rest in the
center of the universe, stimulated further scientific
investigations, and became a landmark in the history of modern
science that is known as the Copernican Revolution.
Johannes Kepler (lived December 27, 1571 – November 15,
1630) was a German astronomer He looked at the solar system
and discovered three laws about how it works.
THE BIG-BANG
One of the best known theories in cosmology is the Big Bang.
This is the idea that our universe started out much hotter and
denser than it is now and has been expanding since then. This
theory is based on observations of our universe, among which
are:
External galaxies are receding in such a way that their
recessional speeds are proportional to the distance they are
away from us (this is called Hubble's Law after Edwin Hubble
who first noticed it). This observation is explained well by a
uniform expansion of the universe. If the universe is expanding,
it must have started out very small some time far in the past. It
is this point which has been called the beginning of the universe
or the "Big Bang."
