Have you heard about water?
They say she's everywhere!
In a puddle, in the sea, in the ocean
And in the water tap.
We are used to the fact that water is
Our companion always!
We can't wash ourselves without it.
Don't eat, don't get drunk.
I dare to report to you:
We can't live without her!

but to you. A glass of ordinary water will become more valuable to you than the countless riches of the whole world.
A grain can lie in dry soil for thousands of years. But

But one day the river became sad, because it became

The little river was overcome by fear.
The river became thin - thin,
She became shallow before our eyes.
The inhabitants of the river gathered together and got to know each other

- They built a factory on the bank of our river and led it to
two pipes for water. One takes clean water to the plant, and
the other pours dirty water into it.
So I became from sewage

Water, you have no taste, no color, no smell, you cannot be described, they enjoy you without knowing what you are! It cannot be said that you are necessary for life! You are life itself!

And he himself is majestic and eternal In a carved granite frame, And all - to the bottom - translucent, And all - down to the drop - dear. And the Hangars fly obstinately, And the scream of the wind, and the hum of the turbines, And the pine birds over the cliff, And the wild wind of the Barguzin. All this, without which you cannot be far and wide and wide And you are unthinkable, Russia, And you are unthinkable, Siberia.

Heavy water slows down the vital functions of the growth and development of many microorganisms. Some bacteria tolerate 70% or higher concentrations of heavy water in the environment, while plant cells can develop normally at heavy water concentrations of no more than 50-75%, and animal cells with no more than 35% heavy water

The Volga is a river in the European part of Russia, one of the largest rivers in the world and the largest in Europe. The length of the river is 3530 kilometers (before the construction of reservoirs - 3690 kilometers).
Slide 12
Currently, about 45% of industrial and approximately 50% of agricultural production in Russia is concentrated in the Volga basin. Of the 100 cities in the country with the most polluted atmosphere, 65 are located in the Volga basin. The volume of contaminated wastewater discharged into the region's basins is 38% of the total Russian total.
Slide 13
Water is the most important substance found in living organisms. What kind of water do we drink? Questions: -Have you ever thought about what kind of water you drink? -Why do you need to boil water? . In water supply laboratories, microbiologists conduct daily water monitoring. The number of microbes in water after special treatment decreases sharply. For example, a study of water in one of these laboratories showed that there were 5639 bacteria in 1 ml cubic meter of river water; after passing water through the sump in the same volume, 138 bacteria were found, and after filtering - only 17 bacteria

The importance of water for humans
In the human body, water: moisturizes oxygen for breathing; regulates body temperature; helps the body absorb nutrients; protects vital organs; lubricates joints; helps convert food into energy; participates in metabolism; removes various wastes from the body. For normal operation of all systems, a person needs at least 2 liters of water per day. Without water, death will occur in 5 days.
Slide 23
Application of water
The industry of our country consumes as much water every second as the Volga carries it. To produce 1 ton of steel, 150 tons of water are consumed, paper - 250 tons, synthetic fibers - 4000 tons. Many chemical processes are accelerated in the presence of water, i.e. water plays the role of a catalyst. But water directly takes an active part in reactions, for example, in the production of acids, slaking of lime, and in hydration processes. Water is required for the processes of setting and hardening of binders - cement, gypsum, lime.

Popular wisdom says: the first bread is bread, the second bread is spirit, the third bread is water. Water protection
Slide 25
Measures to protect water bodies
Monitoring the level of water pollution. Installation of treatment facilities at enterprises; Saving water (turn off the tap, reduce the pressure when you wash your face, brush your teeth, wash dishes, etc.) Planting and protecting plants along the banks of reservoirs. Rational environmental management; Creation of protected areas.
Slide 26
Conclusions:
got acquainted with the physical and chemical properties of water and its composition; gained knowledge about water as the most widespread substance on Earth, identified economic and environmental problems of our time associated with water shortage and pollution through the example of studying the Volga River and Lake Baikal, revealed the role of water in nature and human life, ways of rational use of water resources.

Object of study in my work - water. Object of study in my work - water. Subject of study– the role of water in human life. Goal of the work– study the structure of water and determine its place in human life. Tasks: 1. Study and analyze information on this topic. 2. Find out how a water molecule behaves under various influences on it. 3. Summarize the data obtained and draw a conclusion. My hypothesis: Water is the basis of life on Earth. Research methods:- analysis of literary and historical sources of information;
- generalization of the obtained data.
- The name of water dates back to time immemorial and since that time water has been called any “living” moisture that is so necessary for the life of people, animals and the nature that surrounds us.
- There is no exact definition of why water was called water, since each nation has its own name, which determines the meaning of water for others
Why was water called water?

WHERE IS WATER CONTAINED ON EARTH?
There is also water underground (springs).
Huge accumulations of ice are located at the North and South Poles. There is ice on land and in the ocean.
This is what our planet would look like then. An unpleasant sight, isn't it?
Imagine
what on earth suddenly
all the water was gone.
The body of a jellyfish is 90–95% water.
In the body of animals, water usually makes up more than half the mass.
- Water is found in all parts of plants.
- There is a lot of juice in fruits - watermelon, orange, lemon.
- This juice is water with various substances dissolved in it.
- But even dry plant seeds contain water.

100 g, 85 g - water

A person is 75-80% water. A person is 75-80% water. A person can only live without water for 3 days. Japanese scientist Emoto Masaru proposed a way to record the structure of water Water structure Water molecule Water cluster Water cell The human body is approximately 75-80% water, therefore,
- The human body is approximately 75-80% water, therefore Water is the key to the existence of a healthy body.
- Since water is not just a liquid, but structured substance, the body, for stable operation, requires water with a certain structure.
- Violation or modification of this structures water affects the condition of the body.

Let's learn the poem Have you heard about water? They say she is everywhere. In a puddle, in the sea, in the ocean And in a water tap. Like an icicle freezes. It creeps into the forest with fog, It's called a glacier in the mountains (It creeps into our house with fog, It's boiling on our stove, It dissolves sugar in tea (We don't notice it). We are used to water being our companion always! We can't wash our face without it, We can't eat , don’t get drunk, I dare to report to you: We can’t live without her.
TEST YOURSELF: WITHOUT WHAT WILL THERE BE LIFE ON EARTH? WHERE IS WATER CONTAINED ON EARTH? WHY DOESN'T WATER DISAPPEAR? WHAT CONDITIONS AND PROPERTIES OF WATER DO YOU KNOW? HOW DOES PEOPLE USE WATER? TELL THE POEM TO YOUR PARENTS AT HOME.
