The water cycle
Water on the earth is constantly moving. It is recycled over and over again.
This recycling process is called the water cycle.
a. Water evaporates into the air
The sun heats up water on land, and in rivers, lakes and seas and turns it
into water vapour. The water vapour rises into the air.
b. Water vapour condenses into clouds
Water vapour in the air cools down and changes back into tiny drops of
liquid water, forming clouds.
c. Water falls as rain
The clouds get heavy and water falls back to the earth in the form of rain or
snow.
d. Water returns to the sea
Rain water runs over the land and collects in lakes or rivers, which take it
back to the sea. The cycle starts all over again.

Mixtures
Mixtures




Matter can generally be mixed with other types of matter.
A mixture is a physical combination of two or more pure
substances (elements or compounds)
A mixture is when particles of one substance mixes with
particles of another substance. They are generally pure
substances.
Materials in a mixture can be separated using
techniques such as filtration, screening and
sedimentation


Methods of Separating: sieves, magnets,
air, water, evaporation, distilling, filtering
Methods of Separating

Sieves: can be used
to separate solids.

Magnets: can pick
magnetic objects,
from non-magnetic.
Methods of Separating

Air: you can blow
away lighter
substances, to leave
heavier ones.

Water: some
substances will float
or sink based on their
buoyancy.
Methods of Separating

Evaporation:
evaporate the liquid
and leave the solid.

Distilling: the
processing of
vaporizing into gas
and then condensing
back into a liquid
Methods of Separating
Filtration: using a filter and pouring the
liquid through to separate the solid.

Mixing Gas - Carbon Dioxide
Air is composed of 78% Nitrogen, 21%
oxygen and 1% other gases like carbon
dioxide, water vapour, helium, etc.

That is formed from burning fuel.

Chemical & Physical Changes

A chemical change is a change in matter in which one
or more new substances is produced. This process is not
easy to reverse. Some clues that a chemical change has
taken place are a change in color, the release of gas,
heat, light, or an odor. When you burn wood, the wood is
chemically changed (into ashes) by the fire.
A physical change is a change in matter in which no new
substance is produced. This is usually a change from
one state to another, and can be reversed. A good
example of a physical change is water turning into ice
and melting back into the liquid form again.
Mixture & Compound Review

A compound is a substance that is formed as the result
of chemical changes. A mixture is a substance that
results from physical changes. When atoms of two or
more elements bond to form a new molecule, you’ve got
a compound. Water is a compound, because it is made
up of one hydrogen atom and two oxygen atoms. A
mixture is when two or more elements or compounds are
mixed together, but there is no chemical change.
Lemonade is an example of a mixture—it mixes the
elements that make up sugar and water and lemon juice,
but these elements don’t form new molecules when
they’re mixed together.

An indicator changes colour in the presense of acidic and basic solutions. It
will be one colour for acidic solutions, and another color for basic solutions.
With some indicators, the intensity of the color increases with the intensity
of the acidity of 'basic-ness' of the solution.
Cabbage is a natural indicator.
