In this lesson we will talk about water. Is there a lot of water on Earth? What role does it play in the life of animals, plants and humans? What properties does water have? These and other questions will be discussed in the lesson.
Theme: Nature
Lesson: Water
Let's remember what phenomena of inanimate nature water is associated with. Dew, fog, cloud, steam, rain, snow, ice, frost are all water.
Rice. 1. Water
Water on the globe and on the map is indicated in blue. This color is the most on the globe, because ¾ of the Earth's surface is covered with water. Water is everywhere. Our globe is enveloped in a thick layer of air, and there is also a lot of water, steam, clouds, and clouds in the air. There is also water underground - these are springs. Huge accumulations of ice are found at the north and south poles of the planet, and ice is water.
Water is part of all living organisms. If you crush a green leaf in your hand, you will find moisture. Water is found in all parts of plants.
Remember how much juice is contained in fruits and berries. Juice is also water with substances dissolved in it.
Rice. 2. Fruits and berries
Water is contained even in dry seeds of plants, although in much smaller quantities.
Rice. 3. Plant seeds
The Italian artist Leonardo da Vinci called water the juice of life. And it is true. If we don't water the plants, they will dry out.
In the body of animals, water usually makes up more than half of the mass, and the body of a jellyfish is 90-95% water.
A person can live without water for only 3 days, and without food for 30-50 days. Man himself is 2/3 water. Water is part of human blood. Water evaporates from the surface of the skin and thus regulates our body temperature. Water removes harmful substances from the body. Water is needed for fields and forests; neither animals, nor birds, nor people can live without it. Water not only gives water, but also nourishes. A huge number of fishing boats sail the seas and oceans. Water generates electricity by working in power plants. Water washes everything. And water is the biggest and most convenient road. Vessels sail on it day and night, carrying various cargoes and passengers. All this became available to man only after he studied the properties of water.
Let's take a look at them:
1. Water takes the form of the vessel in which it is located;
2. Water is a transparent liquid;
3. Water flows, moves. This property of hers is called fluidity;
4. Water has no smell;
5. Water has no taste;
6. Water is a solvent, but not for all substances.
Water is life, and people pollute it with waste from factories and factories. To prevent this from happening, it is necessary to build purification facilities, water must be used carefully and economically.

During the classes
1. Organizing time
2. Knowledge update. Formulation of the topic of the lesson
Name the 3 main conditions of life on Earth. (Water, air, sun)
Determine what we are going to talk about today. To do this, guess the rebus (Water)
Let's try to imagine what our Earth would look like if water suddenly disappeared from it. The gloomy bottom of the seas and oceans, covered with a thick layer of salts, once dissolved in the water. Dried up rivers, forever silent springs. The mountains would also collapse, because they contain a large amount of water.
Not a bush, not a flower, not a single living being on the dead Earth. And a cloudless sky of an unusual color.
What will we talk about in class? (About the meaning of water)
Our topic is “Who needs water and why?”
Let's define goals our lesson
1. Clarify who needs water
2. Clarify what the water is for
“Water, you have no taste, no color, no smell, you are enjoyed without knowing what you are. It cannot be said that you are necessary for life: you are life itself. You are the greatest wealth in the world." (Antoine de Saint-Exupery)
If this is wealth, then what should we do (Protect, cherish it)
3. How to save water
Personal goals:
Common goals for the class
3. Work on the topic of the lesson
Group work
- Let's read instruction
1. Tell each other in the group who needs water and why
2. Write your answers in the form of drawings on small sheets. To do this, agree on who will draw what.
3. Open the textbook, find the topic of the lesson. Look at the pictures in the textbook. Complete your answers.
4. Glue the drawings on a large sheet (leave the frames free)
5. Prepare to present to the class
Water beauty slide
Slide hydroelectric power plant
Water can not only be seen but also heard. How? (Sound of the sea, waterfall, rain...)
Hear what it sounds like? (Audio recording - the sound of the sea)
4. Work with proverbs in pairs
Write proverbs about water
Bread is a father, and water is a mother.
Lots of water, lots of grass.
Water wears away the earth, and the stone hollows.
Where there is water, there the garden will bloom.
Glue the compiled proverbs
5. Working with text(work in groups: each group has its own text)
1. Water on Earth is different. Sea water is salty. Mineral water is the most delicious and healthy. Rainwater is dangerous to drink, it can be contaminated with dust, microbes, toxic substances. Clean fresh water is a great value. Glaciers are the main reservoir of fresh water on the planet. .
2. There is a lot of water on Earth and at the same time it is not enough. Most of the water is in the seas and oceans. Sea water is not suitable for drinking because it is salty. The main reserves in the form of snow and ice are in the Arctic and Antarctica.
3. Water is priceless, like air. Nothing can replace her! And if she just runs or drips from your tap - this is a big problem. After all, in order for clean drinking water to get into your home, thousands and thousands of people work day and night. Nature also works, giving people fresh water.
4. There is very little fresh water. Today, more than 2 billion people on our planet suffer from a lack of drinking water. Think seriously about this. You must treat water with care and respect. Don't let her run away from your faucets in vain! Don't pollute waterways!
5. Every day, each of us consumes 200 liters of water. Every day when we brush our teeth, we spend 1 liter of water. Taking a shower for 5 minutes - 100 liters. Each wash of clothes requires 100 liters of water. And through an open tap pours about 1000 liters water per hour.
6. People do not need any water, but only clean water. But there is less and less pure water left. And the people themselves are to blame. All living things suffer from water pollution. Plants and animals die in rivers and lakes. Polluted water is also harmful to humans.
7. No one and nothing on earth can exist without water. Our ancestors drank only pure, living water, and composed legends and fairy tales about it. And now, to purify the water, they are building treatment facilities. We are 70% water. You should drink up to 2 liters of water per day.
At present, no matter how scary it is, people have practically stopped drinking water.
Answer the question: how much water do you drink per day?
Many of you will say: "Oh, a lot - 2-3 liters of water." Very good, Now tell me, please, what kind of water do you drink? I'm sure many will start listing tea, coffee, juice, milk, someone will remember soup, porridge. But wait, where is the water? Or maybe someone showers with tea or soup? Water and liquid are two different things. Any drink can be a liquid, only water can be water. In order to get water from the liquid, the body needs to spend a lot of energy. Many people say that water is not tasty. Of course, especially if you do not drink it at all.
The group reads the information on the card and prepares a presentation in front of the class.
A card with text is glued onto a large sheet.
6. SUMMARY
What is water for?
1. for drinking(Fields and forests drink water. Neither animals, nor birds, nor people can live without it).
2. at home(Without water, you can’t knead the dough for bread, you can’t drink tea without water, you can’t prepare concrete for construction, you can’t make paper, fabric for clothes, rubber, sweets, or medicine - you can’t do anything without water).
3. hygiene product (Water washes all people, animals, cities, cars, roads). In a word, water is necessary to maintain cleanliness.
4. habitat Plants and animals live in the water, which you will not find on land. At shallow depths, where there is a lot of light, the world of animals and plants is diverse. At great depths, especially in the seas and oceans, only animals that feed on other animals live. Many of them have various adaptations for life in the water - fins, flippers, membranes between the fingers, swimming legs, similar to oars.
5. road(Water is also the largest and most convenient road. A person moves on water. Vessels sail on it day and night, carry various cargoes, passengers).
6. To get electric current
7. beauty, knowledge and relaxation(People tend to explore the underwater world, they enjoy the beauty of the water spaces, relax near the reservoirs)
8. feeds (But the water not only "waters", but also feeds - thousands of fishing boats sail through the seas and oceans day and night). There are a lot of algae in the salty waters of the seas and oceans. They feed on aquatic animals. Algae are also used for food, livestock feed and medicine.
Well done guys, now we know that water plays a big role in our lives.
7. Reflection
droplets
Blue color - it was interesting, everything is clear
Half blue - it was not all clear, experienced difficulties
Leave a drop unpainted - it was boring, I didn’t understand anything
Joint educational activities with older children preschool age on the topic: "Why do we need water."
Target:
- Strengthen children's knowledge about the importance of water in our lives.
- To develop the cognitive interest of children in the process of experimenting with liquids, continue to acquaint them with the properties of water.
- To develop the observation of children, the ability to compare, analyze, generalize, establish cause-and-effect relationships, draw conclusions.

- Raise interest in experimental activities, educate careful attitude to the water.
vocabulary work: flood, high water, high water, plumbing, whirlpool, expelled, incompressible.
preliminary work: reading fiction, conversations about water, looking at illustrations, experimental work (experiments with water, looking at a globe, world maps, guessing riddles about water, work in nature
Equipment: models of the properties of water, oilcloth on the table, 3 jars, 3 raw eggs, salt, twigs, ink, syringes, cups, vessels of various shapes, sheets of paper, blue felt-tip pens, plates, aprons, tape recorder, audio recording “Sounds of Water”
Lesson progress:
Educator: Guys, in order to find out what will be discussed today, guess the riddle:
If there are blots on the nose, then who is our first friend,
Removes dirt from face and hands.
Without which, mom can neither cook nor wash,
For rain to fall from the sky, for ears of bread to grow,
For ships to sail, for jelly to boil,
So that there is no trouble - we cannot live without ... (water)
So, we will talk about water, remember what we know, learn new things.
Water is the source of life on earth. It is needed by people, plants, animals. We often use this word in our speech.
Words, like native ones, are a little bit alike,
And if you put them in a row,
Listen a little and think about the essence -
They are talking about the same thing.
Choose the following words (related) to the word "water"
Children: water, water, aquarius, water, waterfall, diver
Disaster. (flood.)
In spring the river floods. (flood, flood)
There are also complex words in which you can also hear the word "water": water turns - a whirlpool,
Water is carried out - plumbing,
Water carries - a water carrier.
Who do you think needs water? (human, plants, fish, animals)
How does a person use water? (drinks, washes, cleans the house, cooks dinner, washes dishes, waters)
Where else is water found in nature? (snow, dew, puddle, seas, oceans, etc.)
Where else is water? (in air, in soil, plants, animals, people)
Oceans, seas, lakes, rivers, ponds, springs are reservoirs. Each of us can be compared to one of these bodies of water. And who do you feel like?
Children: I think I'm like...
caregiver : And what reservoirs do we have in St. Petersburg?
Children: the Neva River, Lake Ladoga, the Gulf of Finland, the Fontanka River, Obvodny Canal, etc.
caregiver : So what needs to be done in order to save our water bodies.
Children : We must conserve water, do not throw garbage, build houses near water bodies, do not wash cars, etc.
Solving riddles:
I am cloud and fog
And the stream and the ocean
And I fly and I run
And I can be glass.(Water.)
They are waiting for me, they will not wait,
And when they see it, they run away. (RAIN)
From the sky - a star,
On the palm of your hand - water. (SNOWFLAKE)
Hanging outside the window
ice cube,
It's full of drops
And it smells like spring. (ICICLE)
In the morning the beads sparkled,
They covered all the grass.
And let's go look for them during the day -
We are looking for, we are looking for - we will not find. (DEW)
Around the water
And drinking is a problem. (SEA)
Fish live warmly in winter,
The roof is thick glass. (ICE)
If the river through the pipe
Comes running to your house
And hosts in it -
What shall we call it? (SHOWER)
It swirls, not smoke,
Falls, not snow. (FOG)
The kettle is on the stove
What is hissing over the teapot? (STEAM)
caregiver : Well done, children! How much do you know about water. But what is water and what properties it has, we will try to find out in our laboratory. But first, let's take a break.
Fizkultminutka "The sea is worried, since ..."
Let's remember the rules of conduct during work: do not make noise - this is how we interfere with others, handle dishes carefully, glass can break and cut easily, listen to the teacher, carefully monitor the result of the experiment.
Before proceeding to research, let's prepare our fingers for work.
Finger gymnastics" BOAT"
The boat floats on the river
Rings run on the water. (Both palms are placed on the edge, thumbs are pressed to the palms (like a ladle).
"STEAMBOAT"
The boat is sailing on the river
And he puffs like an oven. (Both palms are placed on the edge, the little fingers are pressed (like a ladle), and the thumbs are raised up.)
Experiences:
I. Fresh and salt water.
There are 3 jars on the table: 2 half-liter and one liter. We fill one jar clean water and drop a raw egg into it, it sinks. Pour a strong solution of table salt into the second jar and lower the second egg - it floats. Then put a third egg on the bottom of a liter jar and gradually pour in turn from both small jars, the egg will neither float nor sink.
Conclusion: Salt water is heavier, so swimming in the sea is easier than in a river. (Model)
II. Cold and warm water.
Pour warm water into a glass. Drop ink into ice water to color the water. Carefully pour ice water into warm water. Ice water sinks to the bottom, like cold water at the poles.
Conclusion: Cold water is heavier than warm water. (Model)
III. The shape of water.
Children, do you think water has a shape? How can this be proven? (children's answers). Pour water into vessels of various shapes.
Conclusion: Water has no form and takes the form of the vessel in which it is poured. (Model)
IV. Water pushes out.
There are twigs at the bottom of the vessels, the children pour water and see that the twigs rise together with the water.
Conclusion: Water is a buoyant force. A tree is lighter than displaced water, this law was discovered a long time ago by the ancient Greek scientist Archimedes. (Model)
caregiver : Today we learned a lot about water. Tell about it using models. (children's story by models)
We found out that water can be different, found out its properties. What would you draw if I asked you to draw water. What would you draw, Veronica? (ask each child) It turns out that water is a sorceress, it can become different, so it is very difficult for one person to draw a “portrait” of it. But you can all do it together. Draw one view of the water, then we will put all the "portraits" together.
productive activity.
Look, we have a real "portrait" of water. You can immediately see what it is
Don't wash, don't get drunk
Without water.
Leaves won't open
Without water.
Can't live without water
Birds, beast and man.
And so always
Everyone needs water everywhere.
In the future, we will conduct many other experiments and learn about new interesting properties of water.
Many people ask themselves: what is water for and what benefits can it bring? After all, it does not contain any vitamins, nutrients or minerals. But if you just think about it, the answer suggests itself. Our globe is 70% covered with water, and the human body contains approximately 75-80% of liquid. It turns out that water is the basis of all life on planet Earth.
What affects the water supply in the human body
Why a person needs water is quite obvious. With its help, a full cycle of functioning of all processes in a living organism takes place. The fluid inside the cells is called intracellular, due to which metabolic processes are carried out in the human body.
With the help of the basis of life, all digestive processes proceed in the right direction, thereby removing all unnecessary toxins and slags. Human tissues are restored due to the fact that the liquid acts as a transporter of all useful substances throughout the body - this is what the body needs water for.
Interesting facts to know
There are many other useful things that water does that people do not know about. For example, it helps to fight stress and fatigue, increasing the protective function of the body as a whole and increasing the efficiency of the cardiovascular system. If there is a shortage of fluid when taking alcohol, caffeine or some other substances, then by drinking clean water, the desired balance can be quickly restored.
During periods of various epidemics of infectious diseases or influenza, doctors recommend taking a large amount of fluid. Why do you need to drink water in such quantities with a cold and how can it help? The answer to this question is very simple. With its help, antibodies in the blood circulate in the body, which serve as a strong defense against such diseases.
Water also performs an important function of a thermostat. It ensures that the body temperature remains in the desired state if the environmental weather changes or during physical exertion on the body.
If a person is on a diet, and he is overcome by hunger, then you can drink water, since it contains zero calories, but the appetite will go away for a while.
Daily fluid requirement
Everyone can calculate their water supply for a day, which is necessary for the normal functioning of the body. Professional nutritionists have developed a formula according to which he should drink 30 ml of water per day for every kilogram. Thus, if the weight is 50 kg, then, accordingly, to replenish the body's water reserve, you need to drink 1500 ml. This is the total volume of all liquid consumed by a person per day.
It may include first courses, tea or coffee, a variety of juices or drinks. If all this is taken away from the daily norm, then it will turn out that you need to drink about one liter of pure water.
There are many more examples of why a person needs water. For example, it should be drunk as much as possible between meals to avoid distension of the stomach. In the morning immediately after waking up, doctors recommend that you drink warm water on an empty stomach and throughout the day do not forget to replenish the loss of fluid after each urination.
It is generally accepted that the appearance of edema is due to an excess of moisture in the body, but this is not always true. Due to the lack of fluid, such cases are also common, and this is due to the fact that adipose tissue is trying to accumulate water reserves in order to avoid its deficiency.
It turns out that the eyes, hair, nails and skin of a person need fluid. Why is water needed in this case? Everything is very simple - it performs the function of moisturizing them.
What affects the lack of water in the body?
The consequences of dehydration of the human body can be unpleasant. First of all, the lack of fluid is felt by the nervous system, because its organs, namely the brain, consist of water, therefore, it immediately arises. headache. Such disorders can also manifest themselves in the form of other pains, since the lack of water supply is felt in all nerve cells. In this case, it would be best to take not the medicine, but drink a few glasses of water at room temperature.
If you do not replenish the supply, then the digestive tract will suffer second after the nervous system. After eating, discomfort will be felt, since the process of digesting food can take much longer and subsequently constipation will form. A panacea for this violation will also be a few glasses of clean and cold liquid.
What else is water for? It would seem that, in addition to all this, it can still happen to a person if the fluid deficiency is not replenished. In fact, excess weight also appears due to a lack of water in the body, because fats cease to be broken down. In addition, the kidneys, along with the gallbladder, in which stones may appear, also suffer.
As for appearance, then the lack of fluid will affect the hair, which will become dry, and the skin may begin to peel off. In addition, it is possible that the process will not touch the nails, which can exfoliate strongly.
What can be avoided with water?
In our time, various scientific studies have stepped to such a level that they can prevent the occurrence of many terrible diseases. Such as, for example, bladder cancer or urolithiasis. American scientists have found that men most often suffer from these ailments, as they consume less water than the female half of humanity. After a survey of more than 40 thousand people, it was revealed that most of them drink less than two liters of fluid per day, thereby putting themselves in danger. From this we can conclude that in order to reduce the risk of disease by at least 8%, more than one liter.
Another terrible disease is diabetes. One way to deal with it is water. If the body lacks fluid, and subsequently energy, then the brain begins to produce more sugar to replenish this reserve. To avoid this, you need to drink more pure water.
Life-giving moisture in the world of fauna
Why do animals need water? Its functions in the animal body are almost the same as in the human body. They differ only from the species of representatives of the fauna of our planet. Mammals, for example, regulate their body temperature by sweating profusely, so they just need to constantly replenish their water supply.
Carnivores replenish their fluid deficit with food intake, while herbivores drink it thanks to the juices secreted from the plants they eat. But only not in many animals the body can be saturated with the liquid that enters when eating, so you need to constantly consume more and just water.
flora world
Why plants need water is quite obvious. No seed will germinate unless it receives the right amount of moisture. But the most important thing known to many from biology lessons is that it is involved in the process of photosynthesis.
It also ensures the vital activity of the plant, ensuring the flow of minerals and nutrients through its conducting system. And in general, representatives of the fauna will die sooner or later without water, as, in principle, any living organism on our Earth.
Water is practically the most important, necessary and used substance on the planet. Looking outside or into the yard, you will see living plants, people, animals, all of which are almost entirely made of water, look at houses, skyscrapers, fences, cars, all this was also produced with the participation of water. It is unrealistic to do without water in our technological time. Why does a person need water? - you ask. Human beings are almost 72% water. Moreover, there is even water in the bones and enamel of the teeth!
Water is a universal solvent, water, in fact, is an anomalous substance - when it freezes, it expands, and when heated, it contracts. This does not happen with any other substance, which once again proves such an important role of water in human life and activity. First of all, let's talk about the water itself, what it consists of and what it happens to be, the one that we are used to seeing at home, or the one that rushes down the mountain slope, or, perhaps, calmly rushes over, somewhere in the Atlantic .
Water and its types
Water is a combination of two substances - hydrogen and oxygen, as if you can already notice some kind of line or facet - hydrogen, the most common element in space, and oxygen - on Earth, they complemented each other, revealed such strong properties. Now about the water itself - water can be fresh and salty. That is, fresh water is that which is located in rivers, fresh lakes and reservoirs. Salt water is the water of the seas and oceans. So, fresh water, all over the world, is only about one percent! Relative to all world water resources. Only fresh water is suitable for drinking and use. That's really why conserve water.
Fresh water, according to the content of impurities and salts of magnesium and calcium in it, is divided into degrees of hardness. The harder the water, the less usable it is. Consider the degrees:
- Very soft
- Soft
- medium hardness
- Rigid
- Very tough
In our country, usually, the most common water is of medium hardness. Consider also the problems in everyday life associated with hard water:
- When washing dishes, washing, hard water is less effective, because detergents are overused.
- Washing with hard water can cause skin irritation, and washing with soap can cause dandruff and a feeling of “stiffness” in the hair.
- When interacting with soap, hard water forms soap slags, which leave behind stains on surfaces that have been treated.
- Also, the well-known scale on the walls of the kettle is also the result of exposure to hard water. Well, most breakdowns of water heating equipment are associated precisely with scale.
To soften the water, it is advisable to install special filters in order, firstly, to save water, and secondly, to save your health and home appliances - kettles, washing machines, boilers.
Industry
Let's move on to the next section - what is water used for in industry. So, almost no technological process can do without the direct or indirect participation of water. This includes the cooling of units in metallurgy, mechanical engineering, heat power engineering and the chemical industry, and participation in the direct production of bread or sugar. So, for the manufacture of 1 ton of steel, it takes 35 m 3 of water, 1 ton of oil 6 m 3 of water, tons of synthetic fiber - as much as 1000 m 3 of water.
Human
Now let's look at what water is for a person, and what role it plays in the body.
- Water, as a natural solvent, is involved in the water-salt metabolism in the body, that is, it circulates through the body together with blood, delivering nutrients into the cells of the body, and also helps useful substances and trace elements to be properly absorbed.
- Water acts as a means of purification in the body. It contributes to the release of toxins or waste products, in the form of urine and sweat, that is, it performs a detoxifying function.
- Water prevents urolithiasis. As you know, kidney stones are salts that, for some reason, did not dissolve and settled. And water, with more of it, helps to dissolve more salts. That is why, people suffering from urolithiasis are advised to drink more water.
- Water prevents the body from overheating. As you know, in the hot season a person sweats more, this water evaporates, and thus has a cooling effect.
- When a person loses water in large quantities, the body tries to compensate for the loss by narrowing the blood vessels. What leads to an increase blood pressure. What is the use of water in this case? It's simple, water replenishes the body's natural supply and balance, thus preventing life-threatening diseases. Therefore, on a daily basis, it is recommended to use the prescribed norms of water - about 8 glasses, recalculated for food, that is, somewhere around 2 liters of water per day.
- Water, participating in the process of perspiration, helps to remove harmful substances from the skin, giving it more softness and a younger look.
But also do not drink a lot of water, as this can lead to leaching of salts from the body. Thirst is a natural signal of lack of water in the body. Therefore, rely on your feelings and sensations. Thus, why water is needed in the body, we figured out, you can also consider options useful properties water for human use.
Since ancient times, man has been using water for his own purposes, both for hygiene and for the manufacture of all kinds of food products and medicines. Taking a bath or shower, a person cleanses the surface of the skin, making it clean, which is important in the concept of hygiene. Man, making all kinds of medicines and tinctures, still uses water, water is used in almost any industry, anywhere and at any time. Without water, the existence of wildlife as a whole is impossible. Take care of water, it is the source of our life!
