The majority of the world's population still does not attach much importance and does not pay due attention to the availability, quality and quantity of water in our lives. For those lucky enough to live in dry areas, water is of little value, but scientists are very concerned about the condition on Earth. And every day new interesting facts about water are revealed.

Water in numbers

• Now water occupies 70% of the planet's surface, of which only 1% is suitable for human consumption. Of all the world's water resources, this is only 3%, of which only 1.5% is accessible to humans.
• Almost half of all water, namely 46%, is in the Pacific Ocean, the Atlantic Ocean accounts for 23.9% of the water, the Indian Ocean gets 20.3%, and the Arctic Ocean - 3.7%.
• The temperature at which it freezes is 1.91 degrees Celsius.
• There are 8 septillion molecules in one glass of water!
• There are about 1,330 natural types of water on our planet. They are classified according to their method of origin (melt, soil, rain) and composition.

• A person needs about two liters of water per day. Water promotes weight loss: by drinking more than two liters, we enable the body to quickly cleanse itself of toxins. Water dulls hunger well, drunk on an empty stomach or before meals.
• People who drink adequate amounts of water every day are less likely to have a heart attack than those who drink little clean water.
• A person can live only six days without water.
• The body of an adult consists of 70% water, a child - 80%, a fetus at the age of five months is generally 94%!
• During his life, a person drinks approximately thirty-five tons of water. And thirty-three liters of water can be boiled with the energy of the human body released per day.

Conditions of water

We also have access to interesting information about water and its conditions.

• Scientists have found five states of liquid water and fourteen states of solid water.
• Cold water freezes to ice slower than hot water, a schoolboy proved this.
• Ice is denser than liquid water, so it floats on its surface.
• The largest reserves of ice on Earth are located on the polar ice caps.
• Seawater contains protein and many other nutrients.
• Jellyfish are 99% water, and watermelon are 93%.
• the world's oceans are three degrees higher than the temperature of the nearest layer of air.
• There is water in Azerbaijan that can burn due to large quantity methane in the composition.
• In South Africa, the water flowing from the taps is edible without purification - the third purest in the world, and the first place is occupied by the water of Finland.
• A lake in Antarctica is eleven times saltier than the sea and freezes only at -50 o C.
• March 22 is World Water Day.

In order to preserve our vital supplies of water on the planet for as long as possible, first of all, we should treat it carefully and economically ourselves and teach our children to do the same. The child must be interested in any issue. Have conversations with your child in which you tell him interesting facts about water according to his age. All children are maximalists, so information starting with the words “the most, the most” will definitely arouse interest and be remembered!

• The largest raindrop measured 9.4 centimeters! Such drops fell on the United States.
• The longest continuous rain fell in India for almost two years!
• The largest hailstone weighed one kilogram and two grams! It fell in Bangladesh.
• The thickness of the cloud in the sky can be greater; its thickness can reach sixteen kilometers!
• An iceberg can take as long as ten years to melt.

These are not all the interesting facts about water, especially since there are more of them every day. Search, find out, make discoveries yourself to make the world a better and more interesting place!

All the most interesting things about water

Water is the simplest and most common substance on the planet. But at the same time, water is fraught with many mysteries.

The human need for water comes second after oxygen. We need water for life! As you know, a person can live up to 6 weeks without food, but only one week without water.

The chemical compound H2O does not exist in nature in its pure form. Water is a universal solvent; it dissolves everything it encounters along the way. For example, while enjoying the taste of well water, we pour into ourselves a “compote”, the composition of which, perhaps, no one could reproduce.

The most expensive water in the world is sold in Los Angeles (USA). Its price is $90 per liter. According to sellers, the water has an ideal pH balance and exquisite taste for humans. The liquid is sold in special bottles decorated with Swarovski crystals. The water has gained great popularity among wealthy young people, who line up for it in the most expensive nightclubs in California. Hollywood stars have also been spotted among those wishing to purchase exclusive bottles.

A person drinks an average of 35 tons of water in his life.

Water can reduce the risk of heart attack if a person drinks more than five glasses of water a day. However, only clean drinking water has these properties.

You should drink more water if you drink alcoholic beverages, as well as tea or coffee. Because when they are consumed, the kidneys work at full capacity, creating the threat of dehydration.

In Yugoslavia there is Lake Cirknitskoe. In it, water disappears in summer and winter, and returns in spring and autumn along with fish.

Water is the only substance that occurs in nature in three forms: solid (ice), liquid and gas. By the way, only 3% of the water on earth is fresh, but most of the fresh water is contained in a frozen state in glaciers.

The writer Griboedov said in one of his works: “It is difficult to forget the taste of melt water from high mountain streams.” It is believed that it is thanks to melt water that the mountaineers live so long.

Some carbonated drinks contain harmful chemicals that cause dehydration rather than quench your thirst.

One of the most watery foods is watermelon. Watermelon is 93% water.

Approximately 70 percent of the Earth is covered in water. But only 1 percent of this water is drinkable!

There are about 1330 types of water in nature. They differ in origin (for example: rain, soil, from fresh snow, etc.), and also differ in the amount of substances dissolved in it.

American nutritionists recommend getting rid of excess weight using the “water” diet, which is becoming increasingly popular in the West. It has been discovered that when there is a lack of fluid, the body begins to send signals to the brain similar to hunger signals. As a result, people start eating when they should be drinking! By drinking 2-2.5 liters of water every day, a person can suppress hunger and reduce the amount of food consumed. But you need to drink water, since even tea or coffee contain active substances that are harmful to the diet.

There is a lake made of ink in Algeria. You can write on paper with the water of this lake and the ink never runs out.

There is a lake in Antarctica, the water in which is 11 times saltier than sea water and can only freeze at a temperature of -50 degrees Celsius.

A 2% reduction in body water levels can result in a 20% reduction in mental and physical performance.

There are about three million cubic kilometers of fresh water on Earth. Every day, 1 trillion tons of water evaporates from the surface of the earth.

If all the water in the world, contained in various reservoirs, is poured into the open ocean, its level will rise by 3 cm. By the way, in the last 100 years, sea levels around the world have been rising by more than a millimeter per year.

According to doctors, water helps increase blood pressure. And also, as it turned out, best way get rid of swelling - drink a lot of water.

The human body is 60-70% water, and the children's body is 80%. A five-month embryo consists of 94% water.

According to experts, it is enough to drink two glasses of clean water to overcome depression and fatigue.

Water delivers nutrients (vitamins, mineral salts) to the body's cells and carries away waste products. In addition, water is involved in the process of thermoregulation and respiration.

According to UNESCO, the most clean water in the world - in Finland. The study, conducted in 122 countries, took into account the quality and quantity of fresh water.

Around the world, 1 billion 100 million people do not have access to water. So you and I are happy people!

There is flammable water in Azerbaijan! A match causes water to light up with a blue flame due to methane.

The most dangerous water in the world is located in Sicily in one of the lakes. From the bottom of the lake there are 2 sources of concentrated acid, poisoning the water.

A cubic centimeter of seawater contains 1.5 grams of protein and many other nutrients. Scientists have calculated that the Atlantic Ocean’s “nutritional value” is estimated at 20 thousand crops harvested per year across all land.

Recent experiments have shown that water charges food with energy, after which food particles transfer this energy to the body during the digestion process. It turns out that food without water has absolutely no energy value for the body.

About 840 liters of water per day flows through a needle-width stream of water in your tap.

Let's be healthy!

Water is the basis of everything; it gives life to all organisms on our planet. This is her main advantage, and this is her beauty. You can live your entire life without jewelry, without food you can survive for several weeks, and without water, life will be limited to a maximum of a week. There is no more valuable substance than water. And at the same time more “smart”.

The beauty of water is its ability to respond to music, mood, good and evil words. It is known that the crystals of this substance seem to absorb energy and create a wide variety of forms. Scientists have repeatedly conducted experiments over water. One of them was to say the words "thank you, love, appreciation, angel" in different languages. And each time incredibly beautiful crystal shapes were formed. Then the words “fool, I’ll kill, devil” were uttered, but as a result nothing beautiful was observed. The crystals turned out incomprehensible and blurry. Water seems to have a soul that reacts to everything that happens around it.

The water is incredibly beautiful in the sun. How beautiful the streams, rivers, waterfalls are! Beauty is where there is water. Even one drop, even a small dewdrop shimmers with a hundred colors. I remember how, as a child, I was always happy about the snow, because when the sun came out, it seemed as if everything around was strewn with diamonds. Every winter turned into a fairy tale for me. Who among us has not rejoiced at snowflakes while looking at them on our mittens? There are thousands of options, and no two are alike, each is good in its own way. Isn't this a miracle? We are no less delighted by the patterns on the windows in winter and the mysterious fog in the morning. Water is beautiful in any condition, and this is its special feature.

For me, water is a living being. It's better than any mirror. What you give is what you get. It’s not for nothing that our ancestors believed in its power. Living water exists. This is the one to whom we show our good feelings, and who then passes this goodness on to other people. Here is another facet of her beauty.

Water can be warm or cold, fresh or salty, solid, liquid or gaseous. But she is amazing in any condition. Save water, it is our life.

Water in human life

In our everyday life We encounter water all the time. At the same time, to paraphrase a song from an old movie, we can say that we “drink water” and “pour water.” We will talk about these two aspects of human use of water.

Water itself has no nutritional value, but it is an essential part of all living things. Plants contain up to 90% water, while the adult human body consists of approximately 60 - 65% water. Looking into the details, you can note that bones contain 22% water, the brain 75%, while blood consists of as much as 92%.

The primary role of water in the life of all living beings, including humans, is due to the fact that it is a universal solvent of huge quantities. chemicals. Those. in fact, it is the environment in which all life processes take place.

Here is just a small and far from complete list of the “responsibilities” of water in our body.

Regulates body temperature.

Ensures the delivery of nutrients and oxygen to all cells of the body.

Protects and buffers vital organs.

Helps convert food into energy.

Helps nutrients be absorbed by organs.

Removes toxins and waste from vital processes.

A certain and constant water content is a necessary condition for the existence of a living organism. When the amount of water consumed and its salt composition changes, the processes of digestion and absorption of food, hematopoiesis, etc. are disrupted. Without water, it is impossible to regulate the body’s heat exchange with the environment and maintain body temperature.

A person feels extremely acutely the change in water content in his body and can live without it for only a few days. With a loss of water in an amount of less than 2% of body weight (1-1.5 l), a feeling of thirst appears; with a loss of 6-8%, a semi-fainting state occurs; with 10%, hallucinations and difficulty swallowing occur. Losing 10-20% of water is life-threatening. Animals die when they lose 20-25% of water.

Excessive water consumption leads to overload of the cardiovascular system, causes debilitating sweating, accompanied by loss of salts, and weakens the body.

Depending on the intensity of work, external conditions (including climate), cultural traditions, a person consumes in total (together with food) from 2 to 4 liters of water per day and the same amount of water is excreted from the body (for more details, see "Drinking regime and balance of water in the body" and the article "To drink or not to drink - that is the question" from the magazine "Health9 in our Digest9). The average daily consumption is about 2 -2.5 liters. It is from these figures that the World Health Organization (WHO) bases itself when developing recommendations on water quality (See “Water Quality Parameters”).

The mineral composition of water is of no small importance. Fresh water with a total mineralization of up to 0.5 - 1 g/l is suitable for constant drinking and cooking. Although, of course, in limited quantities it is possible (and sometimes even useful, for example, in medicinal purposes) use mineral water with high salt content (about which water is “suitable” for which diseases, see the article “Every disease has its own water” in our “Digest9”). The human body adapts quite quickly to changes in salt composition drinking water. However, the process of getting used to it takes some time. Therefore, with a sharp (and even more frequent) change in the characteristics of water, disturbances in the functioning of the gastrointestinal tract, popularly known as “travelers’ disease,” are possible.

In general, the question of what useful substances and in what quantities should be contained in water is given a lot of attention in the media. This problem is indeed very important, but, unfortunately, there is too much speculation and profanity around it.

Even very reputable publications allow themselves to somewhat irresponsibly publish information like: “a person gets up to 25% of useful minerals from water” and other, to put it mildly, information that does not entirely correspond to reality. A classic of the genre “I heard a ringing, but I don’t know where it is” - the article “Capital water.” by Mrs. Ekaterina Bychkova in “AiF-Moscow9 No. 37”99.

Our point of view on this issue can be found in the section “Water and beneficial minerals”.

It is well known that the use of water for domestic purposes in Russia is far from rational (we will tactfully keep silent about industry due to the lack of reliable data). There are two main reasons:

Abundance of water resources.

In its issue of August 31, 1999, dedicated to water problems, the Itogi9 magazine provided visual data characterizing these two parameters and their relationship.

It can be seen that the cheaper water is in a particular country, the more generously it is poured. It is also not surprising that in Russia, where until recent years there was no practice of installing water metering devices in every apartment, there are no reliable statistics on household water consumption.

Therefore, we will use published English data from the mid-80s. Of course, in Great Britain the daily water consumption per capita was already 140 l/day at that time, and in our country it is still around 400 l/day, but the data collected by the meticulous British is so interesting that we should study it and take note . In any case, the market economy dictates its own laws, it is likely that water will soon become more expensive and the economy of the above-mentioned Englishmen will no longer seem unreasonable to us.

So. According to English data /15/:

The main source of water consumption in everyday life is the toilet. The “gentle contralto of the water-tank instrument” is responsible for 35% of water consumption per capita per day (50 l). Next comes personal hygiene (bathing and showering, washing, etc.) - 32% of consumption (45 l), washing - 12% (17 l), washing dishes - 10% (14 l), drinking and cooking - 3% (4 l), other expenses (pets, watering flowers, etc.) - 8% (11 l).

It is clear that these figures are averaged and reduced to one day (for example, a person does not take a bath and do laundry every day). However, they also provide food for thought and comparison with our reality.

It is unlikely that we eat much more than the same English people and, accordingly, we also spend about 4 - 4.5 liters per capita per day on cooking. Let us be forgiven for such a conclusion, but from the previous one it directly follows that we should not use the toilet more often (or are there other opinions?). Considering that we have the same European standard for flush tanks, this gives the same 50 liters.

By the way, meticulous Englishmen have calculated that a family of two adults and three children uses the toilet on average 25-40 times a day. If you have a habit of flushing leftover food and other waste down the toilet, then the number of flushes9 even in a family of 4 people can reach 60. Here, by the way, we should look for the origins of the environmental initiative that is now fashionable in Europe (especially in Scandinavia). “Give me a brick in the toilet tank!” Jokes aside, they put a brick in the tank, thus reducing the volume of water in it by almost 2 liters. Multiply by the number of flushes per day and you get “net” savings. And if we’re talking about such an interesting area of ​​human life as a toilet, then the future generally belongs to vacuum units (like those installed in airplanes), which consume only 1 (one) liter of water per session.

But let's get back to our sheep. We would also venture to assume that in terms of the level of automation of washing, we have nevertheless reached the level of England 15 years ago, and for this purpose our average per capita consumption is 17 liters.

Where then, as our first president used to say, “did the dog dig”? Why do we use 2 times more water?

To do this, let’s look at what items of water consumption remain: personal hygiene, washing dishes, etc. This is probably where the answer lies. It’s not that we bathe more or wash the dishes more thoroughly. The difference is rather that we are not in the habit of turning off the tap when, for example, we brush our teeth, and we also wash dishes in running water. It would seem like a small thing, but keep in mind that 10-15 liters of water flow out per minute through an open tap. And the second powerful “reserve9” is the “Other9” position. The fact is that “they” in this section practically do not have such an article as leaks. Life simply forces them to quickly fix leaking plumbing - not only water flows, money flows. We can rightfully assert that in our conditions the lion’s share of leaks occurs in houses, so to speak, “after the meter”. And here's why.

The British pay great attention to leaks, but for the reasons stated above, their main leaks occur in the municipal water supply network. In Moscow, according to experts, 15-16% of water is also lost between the water intake station and the apartment (see the article "Moscow Water Drinkers", magazine "Itogi9, 08/31/99). And now, attention, the most important thing. This is not the same what is a bad, but simply an excellent result! In England, losses average 25% and their experts, recognizing the inevitability of leaks, believe that the realistically achievable result to strive for in terms of leaks is 15%. . Honor and praise to Mosvodokanal9. We suspect, however, that on average across the country the situation is rather closer to the English one. However, even if this is so, it still once again shows where we are suffering losses. We, unfortunately, are accustomed to blaming everything on the plumbing, but it turns out that “there is no point in blaming the mirror.” It's time to understand that after the pipes have entered a building (be it a residential building, an office center or an industrial facility), responsibility already lies with the owners and users.

So, you see, in the near future we will also need a brick in the toilet cistern and other “bourgeois” tricks. As the same English say: “The forewarned is already forearmed.”

Stories about water for a child should be exciting and fun! Knowledge about water is necessary if, along with other components necessary for the proper development of personality, you pay attention to such a component as the education of environmental culture. Today, cultivating a correct attitude towards nature and the resources that we use is one of the main tasks of preschool and general education institutions. In the process of working on environmental culture, children need to be taught about water. After all, water is the basis of life on Earth; without this resource, humans cannot exist, and the limited supply of fresh water is forcing entire nations to seriously think about this problem even now.

How to teach children about water?

The choice of topic and method of narration depends on the age of the children. Usually special educational cartoons are used for preschoolers. This way, children can better master the material and perceive information; preschoolers find it easier to hear from the main characters of their favorite cartoon than in a regular lesson.

For children school age possible both in regular classes and in non-standard forms. For example, you can conduct experiments with water in the context of a certain discipline, or watch scientific films about water. It is important to choose the right material and convey really important and interesting information to children.

What to tell children about water?

A story about water for school-age children should include interesting facts and reveal previously unexplored issues.

Water is the basis of life on our planet. At the same time, this substance is one of the most common on Earth. But fresh water reserves are still not very large; some countries are already experiencing great difficulties in providing the population with water, and people there have to save every liter of water.

Watch the video film “About water for a child”:

Humans are 70% water. Some inhabitants of the underwater world consist of 99% water. This once again confirms the theory that life appeared in water and only after millions of years through evolution was it able to reach the surface.

Despite the prevalence of water on Earth, finding it outside our board is quite problematic. If it exists on other celestial bodies, it is only in small quantities or in the form of watery debris with impurities.

Scientists suggest that the presence of such an amount of water on Earth indicates a turbulent history of the planet’s development. According to experts, such water reserves could only be formed as a result of numerous collisions of comets with the Earth. Comets are mainly composed of water ice and cosmic dust.

A person can live without water for only a few days. Water is the basis of many processes in the body. For normal life to the human body You need 1.5-2 liters of water daily.

How to write a story about water, 2nd grade?

For a 2nd grade child, the story should be clear, short, and consisting of a few simple sentences. In the workbook on the world around us, literally a few lines are allocated for this.

So I would story about water compiled like this:

Water is one of the main substances on planet Earth. It occupies more than half of the entire planet - these are oceans, seas, lakes, rivers, pools, springs, streams, reservoirs, waterfalls... All living things are made of water. Without water there is no life. We need to protect water from contamination and save it!

I think that such a story is quite suitable for a second grader - short, clear, about the main thing.

For the second grade, you probably need to write about water, something that a child of this age can understand.

I can offer you the following: Water is the main component of our life, because no one can do without water, neither humans nor animals. Water is very useful, because we drink it every day, cook soups and other various dishes with it. Therefore, it is very important to protect the environment and prevent bad substances from getting into the water that will pollute it. Even our cells in the body consist of 80 percent water; if suddenly there is no water, then all life on earth will die.

Story on the subject The world around us should be both entertaining and interesting. I don’t lay claim to the first half of this definition, but I can tell you some interesting things about water.

First of all, water is a substance that we all encounter in three states at once - in the form of liquid that we drink and bathe in, in the form of snow or ice on which we roll, and in the form of steam that rises from a cup of hot food. tea in the morning.

Water is found literally everywhere - these are rivers and seas, huge oceans and small puddles after rain, this is what flows from the tap in our apartment and what drips on our heads in bad weather. Moreover, it turns out that all living things in nature mostly consist of water - humans, animals and birds, insects, trees and herbs. After all, water is not only part of the various tissues of living organisms, it also consists of the cells that form this organism.

Water is the basis of life. She can be kind and affectionate, but she can also be formidable. It brings us heat, electricity, food and drink, but can bring floods, storms, and landslides.

The water is very beautiful and there is nothing more entertaining than looking at the running water. This sight calms and gives good mood, excites the imagination and even heals.

Water is our everything.



I would write it like this:

Water is the most important part on Earth for human life and the entire animal world. If we look at the globe, we will immediately see that the largest part of the planet is occupied by oceans, seas, and rivers. People need water in order to live. And animals and plants too. Not a single plant can grow if it is not watered. And fish cannot exist without water. Water always attracts people with its beauty. Many artists like to paint landscapes associated with the sea, river, waterfalls, streams. Because water is very beautiful. But besides this, water amazes with its beauty and mystery. Precipitation falling on the ground, rain, snow, hail, also consists of water. And those painted in winter with frost The drawings on the glass windows lure me into a fairy tale.

I would suggest the following version of the story, which would show that the child understands the importance of water for life, knows how to admire its beauty, and is also aware of modern problems of water pollution.

Water is very important for the life of plants, animals and humans. There is a lot of water on our planet. These are oceans, seas, rivers and lakes. They are very beautiful. To live we must drink water. Without water a person will die. In order for plants to grow, they need to be watered regularly. It is very important that the water is clean. But now people often pollute water. It becomes undrinkable. Therefore, we must protect water and protect it from pollution. We must also save fresh water and not waste it.

I think everyone knows that water is one of the most important resources in the world. About a third of the water reserves are located... in the ground. Interestingly, more substances can be dissolved in water than in any other liquid. The freezing point of water can be pushed back by adding salt to it.

In nature, there are organisms that are 95 percent water: jellyfish, cucumbers (vegetable).

Currently, there are countries where more than half of the population does not have the opportunity to use clean water, which often causes various diseases.

It is known that a person can survive without food for about a month, but without water - no more than a week.
