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 H 2 O. 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.

H2O Water in three states liquid, solid (ice), and invisible
(water vapor) in the air. It should be cared. It doesn't last for
ever. types polluted salt drinking 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. 97% of the earth water is salt water.
Salt water is not drinkable because of the salt it contains.
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. we can prevent these things by not throwing our
garbage on the floor or by recycling. Uses There are a lot of uses
but some are good and some are bad. Drinking Recreational Personal

or jet ski etc When we take showers, wash our hands. environmental

Slide 6
Hello 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 Nothing Yestorday i see a program about
save water
Slide 7
Now we learn that water is very important to us to be alive
This is very interesting I want to learn more about water
Slide 8
Ooh, grandpa I hate that rain. ! I hate water Oh, grandson
don't hate water, we use water every day. Grandpa I dont use water
to anything Yes you used, like when you: Take a shower or wash your
hands. there are many things that you yous water every day.
Slide 9
I did not know that We use every da water in something I love
water
Slide 10
Hello Why you are so happy is raining. But i dont like to get
wet. Because is only water Hello did you know that the most part of
the earth is water.
Slide 11
BUT IF THE MOST PART OF THE WORD IS WATER WHY WE HAVE TO SAVE
IT Because it can be finish, and we need a lot the water I dont now
that the water could disappear But if we save it dont would be to
disappear
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.
Slide 23
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.
Slide 24
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
Slide 25
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:

Slide 27
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
