Did you know that March 22 is declared International Water Day? This day is celebrated not because there is a lot of water on Earth, but because it increasingly requires protection. Let's talk about how much water there is on our planet? Is there enough for everyone?
Slide 3

Water comes in different forms, but is all water suitable for our needs? After all, most of it consists of seas and oceans - this is salt water. If you imagine that all the water on our planet fits in a three-liter jar, then fresh water takes up only half a glass. By pipetting just three drops from this glass, you will get water from rivers and lakes. This is so little. Bread, air, water – these are seemingly simple things. But let's think about how much we know about the air we breathe or the water we drink every day? The world of familiar things is fraught with so many mysteries. And scientists have always strived to solve them.

Leading.
With the arrival of water, life appears, the water disappears - and life becomes impossible. But there is a threat hanging over the water - pollution. Plants, factories, cities are often poisoned by wastewater from rivers and lakes. If urgent measures are not taken, the reservoir will die, and the whole world of creatures living in it and near it will die. And it is necessary to protect not only river water, but also that which flows from the tap.
Poet V.V. Mayakovsky addressed the residents of Moscow like this:
Slide 10
Hey townspeople,
Save water!
Be careful with our water supply!
Did you remember to turn off the water tap?
Guys, learn to brush your teeth with the tap closed!

Hello, dear guys and teachers of the School of Arts!

Today we will talk about a very exciting topic. Guess the riddle and you will understand what we are talking about:

That you can't roll up a mountain

You can't hold it in a sieve

And you can’t carry it in your hands (Water)

FIRST SLIDE TURN ON

Indeed, today we will talk about water.

“Water, you have no taste, no color, no smell, they enjoy you without knowing what you are. It cannot be said that you are necessary for life: you are life itself...” (Antoine de Saint-Exupéry)

March 22 is World Water Day. This day is a unique opportunity to remind humanity of the importance of water for the environment and the development of society, for maintaining life on our planet.

We come across water every day, but do we think about it?

Can we live without clean water at least a day?

Are we using a valuable natural resource carefully?

We will have to answer these and other questions during our class hour.

The water element is a beautiful, unique, alluring element. Many works of art are dedicated to water. Differently Artists, sculptors reflected the water element in their works. Let's get to know some of them:

PICTURES ABOUT WATER. SLIDE SHOW

I. Aivazovsky “Among the Waves”

I. Levitan “Fresh wind. Volga"

K. Korovin. "Venice"

V. Polenov. Overgrown pond.

V. Stozharov “Pskov. Kremlin."

Big cascade. Peterhof. St. Petersburg

• The architectural design and sculptural design of the Grand Cascade are subordinated to a clear plan - to show the assertion of Russia's naval power. 64 fountains, 255 bronze sculptures, bas-reliefs, and many other decorative details make the Grand Cascade one of the largest fountain structures in the world.

L. Bernini. Fountain of Four Rivers.

• The fountain symbolizes the strength and power of Italy. The composition is composed in a very original way. These are the four largest rivers in the world from each continent.
  Europe is the Danube, Asia is the Ganges, Africa is the Nile, America is La Plata.

Museum of Water (G.S. – St. Petersburg)

• Exhibits, models and multimedia expositions of the Water Museum tell about the history, current state and prospects of water supply and sanitation in St. Petersburg, the use of water in everyday life, and the state of water resources. In the museum, visitors will learn a lot about the most important substance in nature - Water, in which life originated. The relationship between man and water is presented using the example of the development of the water supply system of St. Petersburg.

Guys, tell me, why do we need water? (Student answers: We drink, wash our hands, bathe, wash things, wash the floor, water the plants, cook food, various types sports: hockey, skating, swimming)

WITHOUT WATER ON PLANET EARTH THE EXISTENCE OF THE LIVING WORLD IS IMPOSSIBLE:

• Plants are 30-90% water, for example: tomatoes - 91%, potatoes - 78%, apples - 85%, cabbage - 94%

• animals - by 75%

• An adult consists of 64% (by weight) water, a child - 85%, in the blood - 73% - 80%, in the bones - 22%, if a person loses 7% of water, he faints, and if 11%, he stops heart

• To take a shower, wash dishes, and wash clothes, city dwellers use 300 liters of water per day.
• Imagine that water is dripping from your faucet. A faulty tap wastes 100 liters of water per day, and if the tap continues to leak for a year, approximately 35,000 liters of clean fresh water will be lost.

SLIDE WITH THE IMAGE OF THE EARTH

• About 70% of the globe is water, but 97% of the water is salty, 3% is fresh. Of these, 2/3 are in the ice of Antarctica. THAT. 1% of clean drinking water remains.

If you imagine that all the water on our planet fits in a three-liter jar, then fresh water takes up only half a glass. By pipetting three drops from this glass, you will get water from rivers and lakes.

Everyone needs water. Water is life. Why did the problem of “water hunger” arise? Have the rivers and seas become thinner, and has there been less precipitation? No! There are several reasons: this is the increased need of humanity for water - in ancient times a person consumed 12-18 liters. water per day, now – 400-600l. We consume clean water, but return polluted wastewater to nature. And there is less and less clean water on Earth. Price for drinking water is growing every year. But the reason is still the same – pollution. The water of many rivers cannot be drunk. That’s why bottles of ordinary water have been sold in Holland for a long time... from Norway, and in Moscow and other Russian cities water is now also sold.

Guys, now for a little “Question and Answer” quiz. Are you ready?

QUIZ: “RIVERS, LAKES, SEAS AND OCEANS”
