Introduction
 This is our presentation about water. Here we are going
to show you many things about water like
Definitions, uses of water, pictures of water, videos of
water, news, comics, graphics, problems and solutions
of water, ways people use water, and G.O. We hope you
like it and learn many things about water. Have many
fun
 In this presentation you are going to see another's
natural resources like hydrogen and oil.
Definition
 Water in three states: liquid, solid (ice), and
(invisible) water vapor in the air. Clouds are
accumulations of water droplets, condensed from
vapor-saturated air.
 Water is a chemical substance with the chemical
formula H2O. Its molecule contains one oxygen and
two hydrogen atoms connected by covalent bonds.
Water is a liquid at ambient conditions, but it often
co-exists on Earth with its solid state, ice, and
gaseous state (water vapor or steam). Water also
exists in a liquid crystal state near hydrophilic
surfaces.
Water in three states
liquid, solid (ice),
and invisible (water
vapor) in the air. It
should be cared. It
doesn't last for ever.

Uses
Drinking
Drinking
water or
potable
water is
water of
sufficiently
high quality
that can be
consumed or
used with
low risk of
immediate
or long term
harm.
Recreational
We use water
in pools and
when we go
to the beach
or jet ski etc…
There are a lot of
uses but some are
good and some are
bad.
Personal
When we
take
showers ,
wash our
hands.
environmental
W
ater tests,
cleaning plates,
boiling ,fishing
etc…
we can
prevent these
things by not
throwing our
garbage on the
floor or by
recycling.
types
polluted
Water pollution is the
contamination of water
bodies (lakes, rivers,
oceans and
groundwater).Water
pollution occurs when
pollutants are discharged
directly or indirectly into
water bodies without
adequate treatment to
remove harmful
compounds.
salt
97% of the
earth water
is salt water.
Salt water is
not
drinkable
because of
the salt it
contains.
drinking
Drinking water
or potable water
is water of
sufficiently high
quality that can
be consumed or
used with low
risk of immediate
or long term
harm.
Hello
Nothing
Yestorday i
see a
program
about save
water
Hello i hear
what you are
sadeding
about water,
so water is
important?
Yes
grandson, if
we don't have
water we will
dead, water
is very
important
This is very
interesting I
want to
learn more
about water
Now we
learn that
water is very
important to
us to be alive
Oh,
grandson
don't hate
water, we use
water every
day.
Grandpa I
don’t use
water to
anything
Ooh,
grandpa I
hate that
rain. ! I hate
water¡
Yes you used, like when
you: Take a shower or
wash your hands. there
are many things that
you yous water every
day.
I did
not know that
We use every
da water in
something
Hello
Why you
are so
happy is
raining.
Because
is only
water
But i dont
like to get
wet.
Hello did
you know
that the
most part of
the earth is
water.
Because it
can be
finish, and
we need a
lot the water
BUT IF THE MOST PART
OF THE WORD IS WATER
WHY WE HAVE TO SAVE
IT
I don’t now
that the
water
could
disappear
But if we save it
don’t would be
to disappear

Problem and solution
Ways people use water
Water resources are sources of water that are useful or potentially useful to humans.
Uses of water include agricultural, industrial, household, recreational and
environmental activities. Virtually all of these human uses require fresh water.
97% of water on the earth in salt water, leaving only 3% as fresh water of which
slightly over two thirds is frozen in glaciers and polar ice caps. The remaining
unfrozen fresh water is mainly found as ground water, with only a small fraction
present above ground or in the air.
Fresh water is renewable resource, yet the worlds supply of clean, fresh water is
steadily decreasing. Water demand already exceeds supply in many parts of the
world and as the world population continues to rise, so too does the water demand.
Why do we need water
Water is probably the most important
resource on earth. We need water to grow
and stay alive. In fact, we could only live for a
few days without drinking water. We also
need water to grow plants and care for
animals, cook our food, bathe and brush our
teeth, flush the toilet, and wash our clothes.
Why do we need to save water
Look at the picture of earth. Most of the earths surface is covered
in water. You might think that there is plenty of water for
everyone to use. But did you know that most of the water on
earth is ocean water? Ocean water is very salty. You cant drink it
or use it for growing plants, cooking food, bathing, or washing
clothes. The water we use for these things is called freshwater. It
comes from rain or snow that falls in rivers and lakes. It is also
found stored in rocks beneath the ground. Some people don't
have enough fresh water where they live. It is important for
everyone to conserve, or save, water so that there is enough for
everyone
What are some ways to conserve water
In the united states, each person uses about 50 gallons of water a day. When
people use water, they often waste a lot. Very large amounts of water go down the
drain without being used. To conserve water, try some of these ideas:
Water cycle
The earth has a
limited amount of
water. That water
keeps going around
and around and
around and around
and (well, you get the
idea) in what we call
the "Water Cycle".
This cycle is made up
of a few main parts:
evaporation (and
transpiration)
condensation
precipitation
collection
