Слайд 2Water, water, everywhere
To wash my hand and wash my hair
It’s nice

to drink it by the pool
Slurp it, sip it, nice and cool

Sick as sick, as sick can be.

Слайд 3Water is the most widespread substance on the Earth, we meet

it everywhere, we all know it. We meet every day: when we drink tea, when we wash up, when we swim and when we jump over the puddles after the summer rain..

Water is the most widespread substance on the Earth, we meet it everywhere, we all know it.

Слайд 4There are 358 rivers which are more than 10km long and

58 of them are more than 50km long. But the main source of water is the Volga.

of its pollution: - Big population; - Dams and water storages; - Salty water; - Oil production; - Garbage;

Слайд 6There are lots of sunken boats and ships on the bottom

of the Volga. The bottom turned into a junk yard.

There are lots of sunken boats and ships on the bottom of the Volga.

Слайд 7Another important problem is blue and green algae, that grows rapidly

into mutants

Слайд 9Engels has a central system of water supply. Water from the

Volga river goes through this system right to our houses and schools. During this process water goes through several stages of chlorination.

Слайд 101. A filter made of grass, sand and coal is useful.

You can drink water after filtration.

2. Put something silver in water. It’s not useful, because silver only helps to keep water fresh, but doesn’t clear it.

Слайд 113. To clear water you need to dig up a hole

in the ground not far from the river and wait for water to fill the hole. This method isn’t useful too. You need to wait for a long time before sediment will be separated.

4.You need to cut banana peel and pour water through it. And it works!!! Banana molecules pull bad substances to themselves.

5. Pour water in the plastic bag and hang it on the tree so that the Sun can go through it. This method doesn’t work. You need much more ultra-violet to make this water suitable for drinking.

3. To clear water you need to dig up a hole in the ground not far from

Слайд 14We also made an analysis of water taken from the Volga

and from our school and come to the conclusion, that water in our school is suitable for drinking only after settling for half an hour, because settling removes the smell of chlorine and the temperature condition is obeyed.
