Water is vital for every person. The only thing more important than water is air, without which life is impossible in principle. A person can live only 3-4 days without water, but without food they can live for almost 3 months. So water should be conserved, especially considering that there is not much that is suitable for consumption, although it covers almost ¾ of the area of ​​our planet. In this article we will present the most interesting facts about water.

Properties of water: interesting facts

At first glance, water is familiar and understandable to each of us. But at the same time, it has not been fully solved, since it conceals many hidden secrets.

Vladimir Dal gives the following interpretation to the word “water”: an elemental liquid that falls in the form of rain and snow, forming springs, streams, rivers and lakes on the earth, and mixtures with salts - seas. Water has infinite potential, it gives life, shows maternal care, heals and purifies.

Facts about the properties of water:

1. It is a well-known fact: water is an excellent conductor of electricity. But the interesting thing is that pure (distilled water) is a dielectric, and electricity is conducted by molecules of impurities and ions of various mineral salts.
2. Another interesting fact: the density of water in the liquid state is greater than in the solid state. Therefore, ice does not sink in water, but always remains on the surface.
3. It's no secret that a person consists of about 2/3 water. In animals this figure is lower. They consist of approximately 50% water. But the most interesting creatures on the planet in terms of their water content are jellyfish, which consist of about 99% liquid.
4. It is noteworthy that hot water turns into ice faster. If you fill identical vessels with hot and cold water, then the hot one will become ice first. This discovery was made in 1963 by Tanzanian schoolboy Erasto Mpemba.
5. Another interesting fact about water: in different states, it reflects light differently. For example, snow reflects about 90% of the light, and water only 5%.
6. If clean water is cooled to -120 degrees, it will become viscous and even viscous.
7. Sea water freezes at a temperature of -2 0 C.
8. It is known that the cleanest fresh water is found in Finland.
9. If a person loses approximately 10% of his body weight in water, he dies.
10. Despite the fact that the Earth is covered with water by almost 80%, only 1% can be consumed.

Mystical properties of water

There is an interesting suggestion that water has memory. Water absorbs any impact and remembers everything that happens around it. When it imprints information and acquires new properties, it changes its structure. Chemical composition at the same time, H 2 O remains unchanged. The structure of water is how its molecules are organized. According to scientists' hypothesis, it is the water molecules that form stable groups of liquid crystals that represent a kind of memory cells where water records everything it sees, feels, and hears.

Konstantin Korotkov, a Russian professor, believes that water is most strongly influenced by human emotions, both positive and negative. Because of love, the energy of water is strengthened, and due to the influence of aggression it is reduced.

Interesting facts about water related to it mystical properties, confirms Austrian researcher Allois Grubber. He believes that if you approach water with positive, good thoughts, thank and bless it, it will be of better quality. Continuing this idea, Japanese researcher Emoto Masaru cites an interesting fact that by drinking water containing this or that information, a person is able to radically change his state. Therefore, before drinking water, Emoto recommends smiling and thanking it.

An interesting fact about water, related to the fact that it carries specific information, was not only theoretically substantiated by Emoto Masaru, but also confirmed practical research. He presented magnificent photographs that reflect the structure of water in various versions (depending on what “impressions” it receives). During laboratory research, he studied water samples, exposing it to different influences. The “impressions” of the water were recorded - it was quickly frozen in a cryogenic chamber, after which it was studied under a microscope. The results obtained were simply amazing.

Water in human life: interesting facts

Water covers 80% of the Earth. At the same time, fresh water makes up 3% (mostly glaciers). As noted, the water suitable for consumption is 1%. And this despite the fact that a person needs about 35 tons of drinking water during his life.

Experts distinguish 1,330 types, classifying water according to a number of characteristics: origin, type and volume of dissolved substances, etc.

It is difficult to overestimate the importance of water in human life. We are 60-70% water. In children and five-month-old embryos, this figure is even higher - 80% and 94%, respectively. Water is very important for the functioning of the whole body. It delivers to the cells nutrients, microelements and vitamins, removes waste products, participates in the processes of thermoregulation and respiration. The researchers also found that when water content decreases by only 2%, irreversible changes immediately occur in the human body. Physical and mental indicators drop by 20%.

This is why scientists advise people to drink 1.5 to 2 liters of water per day. Of course, this indicator may vary depending on weight, time of year, person’s mobility and other indicators. However, we often do not drink enough water, replacing it with different drinks. In this case, the brain sends a signal that the body mistakenly perceives as hunger. This explains the recommendation of nutritionists to drink enough water during weight loss. It is very important to drink water evenly throughout the day.

The benefits of drinking water are difficult to overestimate. So, with just a couple of glasses of clean water you can cope with fatigue and depression. Holidays at the sea or near another body of water are also useful for nervous system and human health. Proven fact: thanks to water, the risk of heart attacks is reduced, a person gets rid of edema and copes with low or high blood pressure. Water brings even more benefits to lovers of coffee, tea and alcohol, as these drinks stimulate the kidneys, which leads to dehydration.

1. There is a unique Lake Cirknicke in Slovenia. In winter and summer it disappears without a trace, and in spring and autumn it fills up.
2. Another interesting fact is that in Algeria there is an amazing lake with “ink” that you can even write with.
3. In Antarctica there is a lake with water 11 times saltier than sea water. Its water is so salty that it does not freeze even at - 50 0 C.
4. Azerbaijan also has a unique reservoir filled with “fuel”. If you bring a match, the water will ignite.
5. The most dangerous water in Sicily. It collects in a lake, at the bottom of which there are two sources of sulfuric acid.
6. The most pure water ended up in Finland. Scientists studied for UNESCO the quality and quantity of fresh water in 122 countries around the world. At the same time, 1 billion people have no access to water at all.
7. The cost of the most expensive liter of water is $90. It is sold in Los Angeles (USA). Manufacturers claim that the water is crystal clear and has an amazing taste. In addition, they decorate bottles with this water with Swarovski crystals. Water is quite popular among Hollywood stars and simply wealthy people who want to demonstrate their status.
8. According to scientists' estimates, reserves fresh water today amount to 3 million km 3, and 1 trillion tons evaporate from the Earth’s surface every day. By the way, the sea level is slowly but surely growing by 1 mm every year.

Glaciers are very important for life on Earth. Thanks to ice, there is a huge amount of fresh water on the planet. In addition, it is glaciers that control the global water level in the world's oceans.

Here are the most interesting facts about ice.

1. Ice has many different names.

Sea ice alone has several names, not to mention the ice in the Arctic and Antarctic. Small broken ice, inland ice, pancake ice, and nilas are only a small part of what is found in the Arctic and Antarctica.

If you sail near the Northern or Southern Polis, then you better know where the iceberg is, and where the bottom of the fast ice is (ice attached to the shore or bottom), and the difference between a hummock and a hummock, a floating ice floe and a floeberg (floating mountain). If you think this is an exhaustive list of terms, you are wrong. Thus, Alaska residents consume more than 100 different types of ice.

1. Freezing rain begins to fall when snow passes through warm and cold layers of the atmosphere.

Ice rain is dangerous for humans. In the process of its formation, it goes through several stages. First, the snow enters the warm layer of the atmosphere, then melts and turns into raindrops. Next it passes through a cold air layer. Raindrops do not have time to completely freeze while passing through this layer. But when faced with a cold surface, the drops immediately turn into ice.

As a result, a thick layer of ice forms on the roads. Ice accumulates on electrical wires, which can cause them to break.

In modern laboratories, researchers are trying to predict how and where freezing rain might strike. One of these laboratories is located in New Hampshire.

1. Dry ice does not contain water.

It is frozen carbon dioxide that can change from a solid to a gas when room temperature and atmospheric pressure, bypassing the liquid phase. Dry ice allows you to maintain the required sub-zero temperature in some products, since it freezes at - 78.5 0 C.

1. Ice helped people invent the refrigerator.

While citing interesting facts about water, we cannot ignore this information. Thousands of years ago, people already used ice to keep food fresh. At the beginning of the 19th century, people cut ice cubes from frozen reservoirs, brought them and kept them in special isolated rooms and cellars. In the late 19th century, people began using household ice boxes for food.

Ice made housekeeping more comfortable and easier. In addition, it has become possible to store meat and other products with a short shelf life in large quantities, as well as to fine-tune their production. As a result, other industries began to develop and improve.

At the end of the 19th century, tons of garbage thrown into wastewater led to the contamination of natural ice reserves. This is what prompted the inventors to create a modern electric refrigerator. The first commercially successful refrigerator was released in 1927 in the USA.

1. The Greenland ice sheet contains 10% of the planet's global glacial ice.

Continuing with interesting facts about water, we note that the Greenland ice sheet is the second largest ice mass in the world, second only to the ice sheet of Antarctica. It contains enough water to raise the level of the world's oceans by at least 6 meters. If all the glaciers and ice cover on Earth melt, the water level will rise by more than 80 meters.

In 2016, the journal Nature Climate Change published a study showing that the Greenland ice sheet is losing 8,000 tons every second.

1. Icebergs and glaciers are not only white.

White light is made up of many colors, each with a different wavelength. As snow accumulates on the iceberg, the air bubbles compress and more light penetrates the ice than is reflected from the bubbles and small ice crystals. This is the secret: ice absorbs colors that have longer wavelengths, such as yellow and red. However, colors with shorter wavelengths, green and blue, reflect light. This is why the hue of glaciers and icebergs is bluish-greenish.

1. There have been many ice ages on Earth.

We believe there has only been one ice age on Earth. But that's not true. There have been many such periods on Earth, and very severe ones. According to scientists, our planet was once completely frozen. Researchers call this hypothesis “Snowball Earth.”

According to a number of assumptions, some ice ages are the result of the evolution of new forms of life: plants, unicellular and multicellular organisms. It was thanks to them that the concentration of oxygen and carbon dioxide in the atmosphere changed so much that the greenhouse effect changed.

To this day, the Earth goes through cycles of warm and cold periods. Researchers now predict that over the next 100 years, the rate of warming will be at least 20 times the rate of previous warming periods.

1. More than 2/3 of the fresh water on Earth is stored in glaciers.

Due to melting glaciers, not only will the level of the world's oceans rise, but also the supply of fresh water will significantly decrease and its quality will decrease. In addition, melting glaciers will lead to problems with energy supply, since many hydroelectric power stations will not be able to operate efficiently - the course of many rivers will change due to melting. In a number of regions, for example, in South America and in the Himalayas such difficulties have already arisen.

1. Ice is not only on Earth.

Water consists of oxygen and hydrogen, and these elements in our solar system a lot. Taking into account the distance from the Sun, the volume of water on the planets is different. Thus, on Jupiter and Saturn, located far from the Sun, as well as on their satellites, there is much more water than on Mars, Earth and Mercury, where the temperature is very high, making it more difficult for hydrogen and oxygen to form water molecules.

Planets far from the Sun have several frozen satellites. One of them is Europa, the sixth satellite of Jupiter. There are several kilometer-thick layers of ice on it. Cracks and undulations were found on the surface of Europa. Most likely, they were formed by waves of the underwater ocean.

Due to the large reserves of water on the Europa satellite, scientists do not rule out the presence of life on it.

1. There is an ice volcano (cryovolcano).

When considering interesting facts about water, one cannot ignore the existence of a cryovolcano. Enceladus, one of Saturn's moons, has a peculiarity. At its north pole there are cryovolcanoes - unique geysers that spew ice rather than lava. This happens when ice deep below the surface heats up and turns to steam, then erupts into the moon's cold atmosphere as ice particles.

1. Ice on Mars could provide clues about life on the Red Planet.

Satellite data confirms that there is ice (both dry and frozen water) on Mars. It is located in the polar caps of the Red Planet and in areas permafrost. Ice reserves on Mars may help reveal a secret that has been discussed for a very long time: is there life on Mars?

In future missions to Mars, scientists will try to find out whether life can be sustained by water reserves that likely come from underground glaciers.

1. A very interesting fact: about 1/3 of male fish in English rivers are at the stage of sex change. This is due to the fact that the water becomes very polluted. Hormones, including those found in female contraceptives, end up in the sewer system. They promote sex change in fish.
2. About a thousand children in India die every day from diarrhea and other diseases caused by drinking dirty water.
3. US residents annually purchase over 29 million plastic bottles water. Their production requires 17 million barrels of crude oil, which would be enough to fuel a million passenger cars for a year. Only 13% of these bottles are recycled. It takes centuries for them to decompose.
4. After the tsunami in Japan in 2011, a floating island was formed that reached a length of 70 miles. This island contains houses, plastic, cars and radioactive waste. Gradually this mass floats into the Pacific Ocean. According to experts, in two years the island will be next to Hawaii, and in another year - to the west coast of the United States.
5. Following the 2011 tsunami and subsequent global nuclear crisis, the Japanese government allowed 11 million liters of radioactive water to be released into the Pacific Ocean. A few days later, radiation-contaminated fish began to be caught 80 kilometers from the coast.
6. Another interesting but sad fact: 7 billion kilograms of garbage, mainly plastic, are thrown into the world's oceans every year.
7. Approximately a million seabirds die every year from plastic waste. Over 100 thousand marine mammals and countless fish are dying from thoughtless environmental pollution.
8. Environmental pollution in China affects the climate of the United States. It only takes 5 days for polluted air to reach the United States from China.
9. The Ganges River in India is considered to be one of the dirtiest in the world. Sewage, garbage, food, and animal remains get into it.
10. Between 1956 and 1968, a Japanese factory released mercury directly into the sea, contaminating fish. Subsequently, people (more than 2 thousand) who ate this fish also became infected with mercury. The outcome for many was fatal.
11. Continuing to present interesting facts about water, we note that the ancient Greek Acropolis was destroyed in just 40 years by acid rain, and not by the precipitation that had been falling for the entire previous 2.5 thousand years.
12. The results of a study of 60 South Carolina beaches showed that the water is most polluted during the peak of high and low tides, which occur during the full and new moons.
13. The Mississippi River brings about 1.5 million cubic meters of nitrates into the Gulf of Mexico annually. Every summer, a “dead zone” the size of New Jersey appears in the bay.
14. Around the world, about 15 million children die every year due to diseases caused by drinking contaminated drinking water.

Popular myths about water

Myth one: tap water is safe to drink

According to many, it is okay to drink tap water. This is true if you live, for example, in Germany. But in Russian cities You can't drink water.

Tap water obtained from a river or spring goes through several stages of filtration and is then chlorinated. It seems like a good idea: filters purify water from debris, bacteria die due to exposure to chlorine. But few people change filters on time, and chlorine poses a danger to both bacteria and people. In this regard, tap water must be filtered.

Myth two: distilled water is very healthy

If we talk in simple language, after heating water to a vapor state and subsequent cooling and re-conversion into water, an ideally pure liquid is obtained - distilled. It contains so few minerals that you can safely use it for any equipment, be it irons, car batteries, humidifiers.

People often believe that in urban environments it is worth drinking this kind of water, since it is completely purified from everything harmful. Since distilled water contains almost no mineral salts and trace elements, it is an excellent solvent, but it is precisely because of this that it is unsuitable for consumption.

The human body needs minerals and trace elements to function normally. The need for them is satisfied by water, and therefore it is not recommended to drink distilled liquid.

Myth three: melt water cures all diseases

Many adherents alternative medicine We are sure that fresh melt water cures everything: increases immunity, heals chronic diseases, accelerates the recovery process - in a word, has only a beneficial effect.

However, melt water is not a medicine. It can be beneficial due to the fact that its structure is similar to the structure of the intercellular fluid. Cells discharge waste materials and dead cells into the intercellular fluid. Melt water is a way to cleanse the intercellular fluid of toxins, renewing it. But under one important condition. Water subjected to freezing must be clean and of high quality. It is best if it is filtered. Such a liquid can be frozen only in strict accordance with the technology, separate clean ice from contaminated ice and use only fresh melt water within 24 hours after thawing, while it “remembers” its changed structure.

Myth four: silver purifies water

Some people believe that if you place a silver object in a container of water, it will become safe to drink because all bacteria will immediately disappear. Is this statement true? Silver purifies water from harmful impurities, but in order for the water to become perfectly clean, its high concentration is required. Of course, silver can be used as a bacteriostatic agent for long-term storage of drinking water, but with one condition. Water must be initially microbiologically of high quality and stored in the dark. No new bacteria should enter it.

Hello, dear blog readers! Every year on March 22, according to the decision of the UN General Assembly, World Water Day is celebrated. The purpose of this holiday is to remind all humanity of the importance of water for environment and human life. Perhaps, having learned a little more about our well-known water, we will think about the need to protect it. Amazing and little known facts about water is the topic of our conversation today.

Our planet Earth is 70% covered with water, 3% of the total mass is fresh water, the rest is water sea ​​water and glaciers. Only 1% is used for drinking purposes.

We have become so accustomed to water throughout our lives that we don’t even notice how necessary it is for our lives. And how many secrets and mysteries it hides! Scientists are still studying it, finding more and more interesting facts. We’ll talk about some of them today.

Water plays a huge role in human life. The human body is 70-80% fluid, most of which is in the intercellular fluid. From the intercellular space, all nutrients, vitamins and minerals are absorbed into the cell, maintaining its functioning.

And, conversely, all waste substances from the cell return back into the intercellular space. If for some reason timely disposal of waste substances does not occur, then the cell begins to consume its own waste. And a pathological process starts, which leads to the development of various diseases.

This process can be normalized if you drink enough clean water. Every day our body excretes up to 2.5 liters of fluid through sweat, urine and feces. In order to human body all physiological processes proceeded normally, it is necessary to consume the same amount of clean water.

Water also participates in the process of thermoregulation and respiration.

Did you know?

From school we remember that pure water has no color, smell or taste; it freezes at zero degrees and boils at 100 degrees Celsius. We also know that it has 3 states of aggregation: liquid, solid, when it freezes and turns into ice, and gaseous - in the form of steam.

Someone may know that when water and alcohol are mixed, the mixture heats up. However, there are still many interesting facts that hardly anyone knows about. Here are some of them.

At a temperature of minus 120º, water acquires unusual properties: while remaining solid, it simultaneously becomes very viscous and acquires viscous properties. And if you cool the water to minus 135º, it will change the crystalline structure to glass-like.

It has already been proven by a student from Tanzania that hot water freezes faster than cold water! This phenomenon was discovered by E.B. Mpemba back in 1963. He put in freezer 2 glasses of water, one of them was with hot water, the other - with cold. And I was surprised to notice that the hot water froze faster than the cold water. He informed his physics teacher about his discovery, to which he replied that this was simply impossible. But they repeated experiments with water freezing more than once, but they never found an explanation for this.

Living and dead water

We remember fairy tales about living and dead water, where dead water helps wounds heal, and living water brings us back to life. These properties of water have been studied for a long time and it has already been proven that with the help of the information received, water acquires special properties. Depending on the environment, water absorbs both positive and negative information, changing the structure of its molecules.

It is believed that “living” water is melt water, and “dead” water is the water that is taken for Ivan Kupala. “Dead” water, despite its gloomy name, helps relieve inflammation and heals terrible diseases. It is not for nothing that before, and even now, people bathe in the Epiphany ice hole for healing.

An interesting experiment was conducted. We took 2 containers of water. Next to one container they turned on music - hard rock, and next to the other - classical music. As a result, it turned out that the structure of the crystals that “listened to” hard rock had an ugly and uneven structure, and that of the one that “listened to” classical music, the water crystals had smooth and beautiful outlines.

Something similar happens if witches or healers cast “bad” or “good” spells on water. By drinking such water, we get sick or, conversely, are healed. It seems that all this is nonsense, but some of my life experience suggests that this is really so.

To remove negative information from water, it is recommended to freeze the water and then thaw it, since when it freezes and then thaws, the water erases all negative information and becomes clean and promotes health by increasing immunity.

Another example of water charged with negativity if someone nearby was swearing. After watering the seeds with such water, the seeds sprouted only half. And if you water the seeds with “holy” water, the germination rate reached 90%. With the help of “holy” water, bad energy in the room is cleansed, therefore, especially on the holidays of Epiphany and Easter, it is recommended to sprinkle the home with such water.

• In Algeria there are lakes made of ink, with such water you can easily write on paper. And in Azerbaijan there is a lake with methane, and when a match is lit, the water lights up with a blue flame. And in Sicily there is a lake that is fed by concentrated acid from 2 sources, such a lake is dead, there is no living thing in it.
• There is a lake in Antarctica, the concentration of salts in which is 11 times greater than in sea water. Such water can freeze at a temperature of -50º.
• Most clean water 122 countries where water is studied, according to UNESCO, is considered to be water in Finland. And 1 billion people on the planet do not have access to safe water at all.

• A person can live no more than 6 weeks without water. A person feels thirsty if the water loss is 2%. With a water loss of 10%, a person begins to hallucinate. A loss of 12% of water can still bring a person back to life if doctors help him, but a loss of 20% already becomes fatal for a person.
• Everyone knows the formula of water - H2O. Such pure water exists only on paper. In fact, water is a universal solvent that can dissolve a wide variety of substances and minerals. Depending on the origin and the dissolved substances present in it, about 1330 types of water are known. This can be spring, melt, rain, soil water, etc.
• The human body is 70% water, the animal body is about half. And jellyfish are 99% water.
• Water is considered one of the most good guides electricity. But pure (distilled) water itself is not a conductor; molecules of impurities and ions of various types conduct electricity. minerals, dissolved in water. This must be taken into account if you are swimming during a thunderstorm, when there is a possibility of lightning striking the pond, and this is already life-threatening.
• Water is not only a source of vitality. Water can serve as a carrier of various microorganisms, which can lead to very serious illnesses, such as cholera, typhoid fever, viral hepatitis A, rotavirus infection, etc. Up to 25 million people die from such diseases every year.

• There is even a rhyme in one children's book: “Close the tap tightly so that the ocean does not flow out.” If you don’t close the tap tightly, 840 liters of water can “drip” in a day.
• Drinking excess water may increase blood pressure, but at the same time it The best way get rid of swelling. And drinking 2 liters of clean water a day will help get rid of depression and fatigue. With the help of water, you can lose extra pounds if you give up sweet soda, tea or juices, and drink plain water.
• The most a large number of water, of course, is contained in the World Ocean. However, the Earth's mantle contains 10-12 times more than the ocean.
• Most of the fresh water reserves are inaccessible to us, as it is contained in glaciers.
• In 1 cubic m of sea water contains 1.5 g of protein and other substances that are very nutritious. It has been calculated that a similar harvest from the Atlantic Ocean alone, in terms of its nutritional value, can produce 20 thousand harvests throughout the entire landmass in a year.

Conclusion

Scientists around the world are sounding the alarm, their forecasts are disappointing: by 2025, the population of our planet, which is 3 billion people, will experience an acute shortage of drinking water. And without water, life on the planet could simply disappear. Therefore, humanity should now think about caring for water resources and look for solutions to preserve them. Let our distant descendants enjoy life on our planet.

With wishes good health Taisiya Filippova

People are so accustomed to water that they do not consider it an ordinary substance, but in reality it is an extremely mysterious substance. She keeps many secrets. Let's consider the most interesting facts about .

The population of hot, arid places on our planet knows firsthand the true value of natural liquid. “Only water is more valuable than gold,” say the Bedouins living among the hot sands. If the life-giving moisture runs out, no treasures in the world will save humanity from inevitable death.

Experts give disappointing forecasts that by 2050 the population will increase from 7 to 9.5 billion people, which will create an urgent need for clean drinking water. Therefore, we need to start explaining its meaning to children from an early age in order to change their superficial attitude towards the “source of life.”

In contact with

Available for younger ages

Problem quality water supply Every year it becomes more and more relevant, and its solution depends only on us and our children. If adults do not teach the younger generation to treat water supplies carefully and rationally, the consequences may become irreversible. Innings useful information must be age specific. A small child under 7 years old cannot comprehend complex scientific terms.

It is better to give to preschoolers explanation in a simpler creative form. For example, read them an educational story about water.

On earth, in one distant state with four oceans and dozens of seas, there lived a good queen. Her name was Precious drop. Her palace was built on the top of a huge mountain. The inhabitants of the kingdom worked from morning to evening, delivering to people crystal clear water. But one day the unexpected happened. The rivers became dirty and muddy, fish began to die, and birds were poisoned. In winter, yellow snow fell with an unpleasant smell.

Without thinking for a long time, the Precious Drop and her assistants went to earth to see what had happened. They returned home barely alive. It turned out, people were careless about natural water: they threw garbage into rivers, poisoned them with household waste, spilled oil and gasoline into the sea. This greatly angered the queen, so she forbade sending life-giving moisture.

People got scared. How will they live now? And they quickly began to correct everything: they cleaned the rivers, stopped pouring out industrial waste, and planted trees along the banks. The good queen forgave the inhabitants of the earth and released clean and clear water to them, but with one condition: preserve water resources and do not pollute them.

Inhabitants of the planet's reservoirs

Children will better remember natural phenomena and bodies of water if you draw a parallel with the animal world or tell something unusual. Interesting facts about water for children will be educational and entertaining.

Land on planet Earth occupies only 20%. The rest is covered by the world's oceans - seas, rivers, lakes, swamps, glaciers, underground rivers. water space is a habitat for many living organisms. A liquid medium contains everything necessary for life: dissolved, carbon dioxide, minerals and nutrients. Tell us more about those who lives in water, for children will find it interesting. A wide variety of creatures live in different layers and seas:

• Inhabitants of the surface of natural reservoirs are small crustaceans, microscopic algae, and protozoa.
• Diversity of living organisms inhabit the depths of the ocean. Live here different kinds fish, shellfish, turtles, mammals (walruses, whales, seals, dolphins).
• At depths, where the habitat is completely different, in complete darkness, at low temperatures, enormous pressure and a minimal amount of oxygen, life also exists. In such conditions, only small individuals can survive - bacteria, sea ​​urchins, bottom fish, corals, crustaceans, algae. Many inhabitants of the deep sea are capable of emitting light themselves.

Attention! Depth 11 km. If you throw an object into the sea at this point, it will reach the bottom only after an hour.

Knowledge about who lives in water, for Children will understand it more clearly if they reinforce theoretical material with practical actions, for example, take them on an excursion to the aquarium or go to a real body of water.

Do you know?

Students will certainly be interested in the following information:

• A person can live 6 weeks without food, and 5 days without drinking.
• A tomato is 90% liquid, and a watermelon is 93%.
• The most watery animals on globe considered a jellyfish, her body contains 99% fluid.
• Hippos are born underwater.
• Koalas hardly drink; it is enough for them to eat eucalyptus leaves.
• Snakes do not bite in bodies of water.

Explanation for schoolchildren

Teenagers can be given more rich information on the topic “what is water.” The aquatic environment is the basis of life on Earth. When exploring other planets, probes are first sent to search for water resources, because without this absolutely nothing can exist. On our planet, liquid is found almost everywhere: on the surface of the Earth, in the mantle, atmosphere and in every living organism.

From the knowledge acquired at school and scientific articles, we know three physical states of water:

• liquid,
• solid - ice,
• gaseous - steam.

In order for a transition to occur from one state to another, the temperature regime must be changed. In its normal state, this element is liquid, but if it is heated to a temperature of 100°C, it produces steam. When the temperature drops to 0°C, the liquid turns into ice. This is the only substance in the world that can exist in three states.

Not long ago it became clear what is natural water has at least 5 different phases. An American group conducted a series of experiments and told the world about a new state in which the liquid does not freeze even at -38°C, and when the temperature drops to -120°C, even stranger things happen - it becomes sticky and viscous. The temperature was dropped to -135°C, and it became like glass, that is, solid, but without a crystalline structure. Scientists gave it the name “nanotube water” because they used carbon nanotubes. The research turned out to be fruitful, so new work is coming in the laboratory.

Adults, not to mention children, are curious about unique features of the substance. Until now, researchers have not been able to discover all its secrets. One of its phenomena is the ability to remember and store information. Its properties may change depending on the environment. It can also absorb positive and negative energy, changing the structure of molecules.

The following experiment was carried out: 2 glasses were filled with liquid and placed in different rooms. Classical music was playing next to the first glass, hard rock music was playing next to the second. When samples were taken for analysis, it was found that crystals of matter listened to the classics, had smooth and beautiful shape. And the structure of the crystals, listened to rock, has become torn and cut.

The scientists who prepared the report on the properties of H2O note that memory records can change when a substance transitions from one state to another. If you freeze a liquid with bad energy, then when it thaws, all the negativity is erased. Exactly neutral liquid carries a positive charge to the body. However, scientists do not have a clear explanation for such natural phenomena, although they do not exclude the possibility that even more incredible information will appear in the future.

Unusual facts about water:

1. The ocean temperature is +17.5°C.
2. A person drinks 35 tons of liquid in his entire life.
3. The most clean water resources are found in Finland. This conclusion was made by UNESCO after studying 122 countries of the world.
4. Turns out, ice has different temperatures. In Antarctica -60°C, in Greenland -28°C, in the Alps -0°C.
5. In a Yugoslav lake Tsirknitskoye the water resource disappears in winter and summer, and returns in spring and autumn along with fish.
6. The conductivity of sound in water is greater than in air.
7. In the American city of Los Angeles, water is available for sale for rich people, costing $90 per 0.5 liter. Sold in special bottles decorated with Swarovski stones. They say that such a liquid has an optimal pH and a unique taste.
8. The saltiest ocean is the Atlantic on the ground.
9. There is a flammable aqueous liquid native to Azerbaijan. It burns with a blue flame due to the presence of methane in it.
10. A scientific article says that the longevity of mountain people is associated with the consumption of moisture from mountain streams.

Interesting facts about water - The Mystery of Water

Conclusion

Even in the last century, the quality of water bodies did not worry humanity much, but at the turn of the third millennium, environmentalists are sounding the alarm. Every year, 13 million tons of oil waste ends up in the World Ocean. And this is only the oil refining industry, not to mention toxic chemicals, heavy metals, and sewage.

WHO stated that there is no absolutely pure natural source left on the planet. All this threatens a catastrophe on a universal scale.

Water is the simplest and most common substance on the planet. But at the same time, water is fraught with many mysteries. Scientists still continue to explore it, finding more and more interesting data about water.

• Fact one: the cleanest water in Finland
  According to UNESCO, the cleanest water is in Finland. A total of 122 countries took part in the study of fresh natural water. At the same time, 1 billion people around the world do not have access to safe water at all.

  

• Fact two: it’s faster to get ice from hot water
  Which water will turn into ice faster: hot or cold? If we think logically, then, of course, it’s cold. After all, a hot one must first cool down and then freeze, but a cold one does not need to cool down. However, experiments show that it is hot water that turns into ice faster.
  There is still no exact answer to the question why hot water freezes faster than cold water. Perhaps the reason is the difference in supercooling, evaporation, ice formation, convection, or the reason is the effect of liquefied gases on hot and cold water.

  

• Fact three: supercooling water
  Everyone remembers well from the school physics course that water freezes at 0 degrees and boils at 100 degrees. However, there is a so-called supercooling of water. Very pure water has this property - without impurities. Even when cooled below freezing, such water remains liquid. But in both cases, there are temperatures at which the water will become ice or boil.

  

• Fact four: water has more than 3 states
  Since school, everyone knows that water has 3 states of aggregation: liquid, solid and gaseous. However, scientists distinguish 5 different states of water in liquid form and 14 states in frozen form.

  

• Fact five: water is like glass
  What happens if you take frozen clean water and continue cooling? Miraculous transformations will occur with water. At minus 120 degrees Celsius, water becomes super viscous or viscous, and at temperatures below minus 135 degrees it turns into “glassy” water. Glass water is solid, which lacks a crystalline structure like glass.

  

• Fact six: the basis of life is water
  Water is the basis of life. All living animals and plant beings consist of water: animals - 75%, fish - 75%, jellyfish - 99%, potatoes - 76%, apples - 85%, tomatoes - 90%, cucumbers - 95 %, watermelons - by 96%. Even humans are made of water. 86% of water is contained in the body of a newborn and up to 50% in older people.

  

• Fact seven: water is a carrier of diseases
  Water not only gives life, but can also take it away. 85% of all diseases in the world are transmitted by water. Every year, 25 million people die from these diseases.

  

• Fact eight: a person dies without water
  If a person loses 2% of his body weight in water, he becomes very thirsty. If the percentage of lost water increases to 10, then the person will begin to hallucinate. With a loss of 12%, a person will not be able to recover without the help of a doctor. With a loss of 20%, the person dies.

  

• Fact nine: most fresh water is in glaciers
  Where is the most water? The answer seems obvious: in the World Ocean. However, in fact, the Earth's mantle contains 10-12 times more water than the World Ocean. At the same time, almost all the water available on the planet is not suitable for drinking. We can only drink 3% of the water - that’s how much fresh water we have. But even most of this 3% is inaccessible, as it is contained in glaciers.

  

• Fact ten: water as a diet
  With the help of water you can fight overweight. By consuming only water from drinks, you can sharply reduce the overall caloric content of your diet. Firstly, because a person stops drinking high-calorie sweet sodas and juices, and secondly, because after drinking water there is less desire to take sweets, as is the case with tea or coffee.

  

• Fact eleven: water for a healthy heart
  Water helps reduce the likelihood of a heart attack. During the study, scientists found that those people who drink about six glasses of water a day are less at risk of heart stroke, unlike those who drink only two glasses.

  

• Fact twelve: 35 tons of water in a lifetime
  A person cannot live very long without water. The need for water comes second after oxygen. A person can live about six weeks without food, and five to seven days without water. Over the course of his entire life, a person drinks approximately 35 tons of water.

Water is one of the most basic human needs. The only thing that matters is oxygen. Without it, life is not possible at all; without water a person can live only 3-4 days, but without food you can last almost 3 months. So you need to treat water very carefully, because there is not so much drinkable water on Earth, despite the fact that three-quarters of the planets’ area is covered with water.

1. Water is the chemical compound H2O. But it is a unique universal solvent. This is why it is impossible to find clean water in nature. Water absorbs many substances and compounds encountered along the way. As a result, a person does not consume pure water, but a complex solution with many different components. By the way, an interesting fact: only water is found on Earth in three states at once - liquid, solid and gaseous.

2. It is known that 70% of our planet is covered with water, of which 3% is fresh (mostly in the form of glaciers), and only 1% is suitable for drinking! And this despite the fact that a person needs 35 tons of drinking water on average throughout his life. In general, water experts identify 1,330 types of water; classifications are carried out according to various criteria - by origin, by the type and amount of dissolved substances, etc.

3. As already mentioned, a person cannot exist without water. After all, we are 60-70% made up of it, and for children and five-month embryos this figure is even higher - 80% and 94%, respectively (and a watermelon is 93%). The role of water in the life of the body is difficult to overestimate. It is responsible for the delivery of nutrients, vitamins and microelements to cells and the subsequent removal of waste products, participation in the processes of respiration and thermoregulation. In addition, scientists have shown that it is enough to reduce the water content in the body by 2%, both mental and physical indicators people fall by 20%.

4. That is why it is recommended to consume 1.5-2 liters of water per day per person. This indicator, of course, should be selected individually depending on weight, time of year, person’s activity, etc. But people often do not drink enough water or replace it with various drinks. And the brain sends a signal that is mistakenly interpreted as hunger. Thus, drinking plenty of fluids is the basis of a simple and now popular diet. The main thing is to drink evenly throughout the day, and only clean water counts, which should be either a little cooler or a little warmer than body temperature.

5. The benefits of water for the body cannot be overestimated. So just a couple of glasses of clean water can help overcome fatigue and depression. A holiday at sea is also very useful, where there is an opportunity to show off your one-piece swimsuits and original swimming trunks. The same water can also reduce the risk of heart attacks, relieve swelling and increase blood pressure. Water is even more beneficial for lovers of coffee, tea and alcoholic beverages, which stimulate kidney function, which in turn leads to dehydration.

6. There is a unique Lake Cirknitskoe in Yugoslavia. It behaves cyclically - completely disappearing in winter and summer, and replenishing along with fish in spring and autumn.

7. There is a unique lake in Algeria that is filled with “ink”. You can even write with this water.

8. And in Antarctica there is a lake with a salinity 11 times greater than sea water. It is so salty that it does not freeze even at -50 degrees Celsius.

9. Azerbaijan can boast of flammable water. It is enough to bring a match to the water and it will light up with a blue flame.

10. The most dangerous water can be found in Sicily. It collects in a lake, at the bottom of which there are two sources of sulfuric acid. There may even be lakes.

11. But the cleanest water was in Finland. Scientists for Unesco conducted a study of the quality and quantity of fresh water in 122 countries. But at the same time, more than 1 billion people have no access to water at all.

12. A liter of the most expensive water costs $90 and is sold in Los Angeles (USA). Manufacturers talk about crystal purity and amazing taste, and actively decorate the bottle with Swarovski crystals. It seems that, first of all, amateurs are chasing this kind of water; this water is more of an indicator of status. After all, Hollywood stars also take up such bottles.

13. It’s not just the water you ingest that can pose a danger. Water also collects substances in the pipeline, which can lead to serious consequences after a shower. So a very small amount of manganese can be inhaled during a long shower, which has a strong effect on the nervous system...

14. Scientists now estimate fresh water reserves at 3 million cubic kilometers, and 1 trillion tons evaporate from the earth’s surface every day. By the way, the ocean level is gradually rising, the growth rate has been 1 mm per year for the last hundred years. Another interesting fact about water reserves. It turns out that the water reserves in all reservoirs can raise the level of the World Ocean by as much as 3 cm.

15. It turned out that sea water contains as much as 1.5 grams of protein per 1 cubic centimeter, and other nutrients are present in it. Thus, in the Atlantic Ocean alone, 20,000 harvests are dissolved, equivalent to the annual harvest of the fields of the entire Earth.

16. Economic fact. If there is a leak in the house, then a trickle just a needle thick can carry 840 liters per day.
