Why the sky is blue for kids. Why is the sky blue? The expression about the blue sky in English translation

How much does reading mean in your life? How often do interesting articles about everything brighten up your leisure time? Do you draw any new information, getting acquainted with the material on countless Internet pages? FUN READING: ARTICLES ABOUT EVERYTHING IN THE WORLD Unfortunately, there is not always time to read informative, noteworthy books. A lot of material scattered on the resources of the Internet, of course, will not make up for the lack of classical or avant-garde creativity, but will significantly broaden one's horizons. Regular acquaintance with the information periodically appearing in the virtual press turns into a pleasant habit. In addition to the Internet, printed publications are becoming a source of information. Many people prefer to read articles in newspapers and magazines, getting news from there. It doesn't matter where we get the data from. The main thing is not to let your brain level out, saturating it with interesting and necessary information for yourself. The circle of readers' interests is multifaceted. Someone enthusiastically reads informative articles, while someone can only be captivated by entertaining lines. Tastes, as they say, do not argue. But there are people whose sphere of knowledge is not limited to something specific. This is a category of active readers, constantly developing, inquisitive and tireless. They need to know everything. As children, they broke toys and tried to repair them themselves, assembled locomotives from the designer and painted the walls in the apartment, sewed dresses for dolls and, secretly from their parents, took apart an old TV set. Such children listened with equal interest to informative articles and fairy tales, watched programs about space and historical films. Today, they are the most grateful readership. There are still a lot of subcategories such as "garden and vegetable garden", "sports news", "do-it-yourself repair", "tourism, travel", etc. Well-written interesting articles about everything always find their reader. The main thing is an attractive presentation of the material, an accessible language. Of course, a worthy plot To, while reading, forget about everything in the world, wanting to quickly reach the end and learn something new. It's funny to watch how the interests of the female and male audiences differ. It is clear that Interesting Facts and articles about fashion trends, breaking news from the world podiums are unlikely to attract a strong half of humanity. They will certainly not be interested in the techniques of embroidery, beading, the nuances of creating home comfort. Interesting articles about health and recipes can “hook” both of them: many culinary shows of modern television are conducted by male chefs of expensive restaurants. And this exception, which previously served as nonsense, today is rather the rule. Men now love to cook, willingly share recipes, participate in culinary programs and are happy to teach this to others, proud of their achievements in the field of cooking.

WOMEN'S INTERESTS

Another thing is women. There are a lot of magazines and Internet portals offering interesting articles for women on any topic. Do not want to think too much, try to relax and read without thinking about what you read? Then secular rumors, news of the show world, reliable (and not so) facts from people's lives, diligently collected by editors from all over the world, are for you. Do you want to digress into serious reading? At your service - interesting articles about health, telling about the prevention, symptoms and treatment of various diseases. Someone needs it to solve their own problems, someone opened the page for general "development". Agree, from such sources we get really a lot useful information! What can cause a headache? Why does he twist his leg? Why did spots appear on the skin, etc. How to treat, what to buy, what to do - you should not rely on the reliability of what you read 100%, but you can take the information received as a basis. Glossy magazines and their Internet counterparts print interesting articles for girls. Such resources never suffer from a lack of their attention. Perhaps, fashion news and gossip columns are the priority here, but these data are always in great demand.

ARTICLES FOR MEN

What do men read? In addition to sports news (who played - who won - at what minute the ball was scored / got knocked out), they are interested in automotive articles and materials related topics. New car models, achievements and innovative developments in this area, modern tuning and much more, thanks to which the car enthusiast not only raises the general educational level, but also, perhaps, is preparing for something important in life, for example, to purchase a new car. More serious attract news of technology and new technologies. The knowledge gained is not necessarily applicable in practice, but quite interesting, especially modern science daily makes a march-throw forward in its development. Technology that was relevant six months ago will be obsolete in six months. Every day we get news high technology, educating us about computers, phones, various newfangled gadgets. Group video chats, artificial intelligence, robotics and more - you don't have to be a nerd to read informative articles about this and more.

ARTICLES FOR THE GENERAL AUDIENCE

When buying a magazine to read at home, think about your neighbor! Let there be interesting articles about life in it - it is always interesting for both. After all, after reading, you can share opinions, and this unites, like any common cause. Any material you read can be an occasion for discussion. Why not set the tone for the evening conversation? Especially if the news is fireworks that can amaze the imagination? Even a woman can be interested in automotive articles if they are not about the causes of squeaking brake pads or suspension clatter, but about the latest models of your favorite car brand. And if this model was created specifically for women, then the article is definitely a must-read! There will be something to tell your friends about, and to formulate an idea for your husband, using exact names and numbers, and not just “I like that little, red one over there!” Both halves may well be interesting science articles if they deal with the facts of longevity, understandable discoveries, achievements. In this perspective, women will probably read the news of technology and new technologies, especially when the article talks about intelligent vacuum cleaner models, food processor, new phones or tablets. Expanding your horizons does not happen by itself. Our brain receives data from the outside, processes it and gives it to us in the form of thoughts, which we transform into speech. So, interesting facts and articles can be useful for a person who often stays in society. When you come to work in the morning, don't you share your impressions about the news you heard or read? Automatically, you become a respected colleague and an interesting conversationalist, your social rating increases many times over. Reading interesting articles about life, analyzing other people's experience, we involuntarily try on ourselves in the place of another person, thinking what we would do in his place. Thus, we prevent potential mistakes that we could make in a similar situation. PERMANENT READING. MOTIVES AND Aspirations We try to read articles about things that can give us emotions. It doesn't matter what - the main thing is to get something that will make us think, talk about it, analyze, reason. We can say with confidence about the main functions of reading: With a sensible presentation of the material, any of the articles will perform them together. In other words, each of them MUST meet these requirements: interesting facts and articles should arouse the desire to talk about them, they should be “digestible” and pleasing to the eye, and they should contain maximum useful information for the chosen topic. There is another feature of reading, testifying in his favor. The habit of reading articles teaches empathy, which is so lacking in modern world. This, of course, is not about scientific topics. Reading interesting articles for women, we experience together with the people on behalf of whom the story is being told. Even a little experience gained as a result of processing such material sometimes changes the attitude to life. Naturally, interesting scientific articles do not evoke such feelings, but they can also surprise, convince, and delight. Reading articles, we form our worldview. By sharing experiences, we inspire others. By discussing what we read, we arouse interest and respect for ourselves. It's not just a pastime. It is the pleasure by which we develop.

The sky is infinity. For any nation, the sky is a symbol of purity, because it is believed that God himself lives there. People, turning to the sky, ask for rain, or vice versa for the sun. Mankind has long wondered why the sky is blue. A lot of hypotheses and assumptions were invented. So, …

The sky is just the air that we breathe every second, the one that cannot be seen or touched. But we breathe transparent air, why does it acquire such a blue color overhead?

The air contains several elements, nitrogen, oxygen, carbon dioxide, water vapor, various dust particles that are constantly in motion.

The reason for everything is the SUN. The sun not only gives us light and heat, but also paints everything around us in the rainbow colors of the spectrum.

Spectrum is a palette of colors

A beam of white light is actually multi-colored, we know this from its reflection in a raindrop, which became a rainbow.

To remember the colors in the rainbow, you should remember the phrase: "Every Hunter Wants to Know Where the Pheasant Sits"

Then why did the sun choose blue for the sky, and not green, for example? Imagine if the sky were green...

The earth is surrounded by a layer of air - the atmosphere. The thickness of the atmospheric layer is about 500 kilometers. When the sun shines on Earth, the sun's rays need to pass through a huge layer of air. Passing through this layer of air, the ray scatters the various colors of the rainbow in all directions, but the blue color is scattered most of all, due to which the sky acquires a blue color. Briefly described, the blue sky is the spray that gives a beam painted in this color.

But the sky is not always blue, it tends to change color. Why is that?

For example, at sunset, we often see red skies... When the sun is low, the blue light is very strongly absorbed and only red remains. And when the sun is high, absorption is low and the sky is blue.

And at night, when the sun does not send its rays, we see the sky is not blue, the atmosphere seems transparent to us. And through the transparent air, a person can see planets and stars. And during the day, the blue color will again reliably hide the mysterious space from prying eyes.

For the same reason, the sea is blue.

The color of the sea that we see is the result of the scattering of sunlight by the sea water column. Water transmits light unevenly - it scatters short waves better, and long waves worse. Short waves correspond to the blue part of the spectrum, and long waves to the red. In the decanter, you are looking through the light at a thin layer of water, so the difference in the transmission of the rays is not noticeable. And in the sea, you see the result of the scattering of sunlight by many meters of water. Therefore, blue light is absorbed less in water, and in the light that comes out of the water, most of blue color.

“Mom, why is the sky blue and not red or yellow?” Many parents are confused by this phrase. It turns out that we, adults who introduce our baby to the world around us, do not ourselves know the answer to such a “difficult question” and simply, not knowing what to answer our baby, we translate the topic, or, in order to compose an explanation accessible to the child, we have to rack our brains . Therefore, let's figure it out with you why the sky is blue and how to explain it to a small child in a simple way.

Light, consisting of seven spectral colors, passes through the atmosphere. Solar photons collide with gas molecules in the air, causing them to scatter. And the most interesting thing is that after that, the number of particles emitting a short wave of blue becomes eight times more than others. It turns out that before our eyes, sunlight on the way to Earth turns from white to blue.

How to explain all this to a child? It is still too early to talk about solar photons colliding with gas molecules. We offer several versions of the answer to this difficult question.

Why is the sky blue?

Sunlight is made up of 7 colors combined together: red, orange, yellow, green, blue, indigo and violet. (Look at the pictures with the spectrum, remember the rainbow.) Each ray passes through a thick layer of air high above us, as if through a sieve. All colors at this moment are splashed and it is blue that becomes the most visible, because it is the most persistent.
The air looks transparent, but it actually has a bluish tint. The sun is very far away. When we look up at the sky, we see a very thick layer of air, so thick that we see that it is blue. You can take transparent cellophane, fold it many times and see how it has changed color and transparency. And then draw an analogy.
The air around us consists of tiny and constantly moving particles (gases, dust and specks, water vapor). So small that they can only be seen with the help of special devices - microscopes. And sunlight combines 7 colors. A beam passing through the air collides with tiny particles and its constituent shades are separated. And since blue-blue prevails in color scheme, we see it. Here it is necessary to show the child the spectrum.
And you can do it quite simply - the sun paints the air blue.

If the child is very small and it’s too early to talk about spectra, then you can just come up with something (options from the forums)

kitty Well, for example, like this: there is such a magician in the world who has a brush with beautiful blue paints, he wakes up, and so that the children are light and joyful, he takes out blue paint and paints the sky with it, the paint is also magical - it does not spill and immediately dries , but when he is upset, the sky is not blue, but dark blue and the paint does not dry, but it rains, and the wizard has a fairy sister, and when she sees that the children are tired, she draws the sky in dark color and throws stars so that it is not very dark, and then the children have colorful dreams

Vladimir Gor There are many seas and oceans on earth (show on the map) and in sunny weather the water is reflected in the sky and the sky becomes as blue as the water in the oceans and seas, just like it happens in the mirror (show something blue in the mirror) . This will be enough for the child to satisfy his curiosity.

Chena A fairy flew, she had paints in her basket, a bottle of blue paint fell and the paint spilled, so the sky is blue. In general, it all depends on the age of the baby ...

It is very important to involve your child in the discussion. Sometimes invite your why child to first think about the answer to the question. Try to hint, push him to conclusions. And then discuss and summarize the information. The baby needs your attention, recognition of his interests and respect for the first attempts to know the world. In this way, you will help develop your child's open and inquisitive personality.

Moms take note!

Hello girls) I didn’t think that the problem of stretch marks would affect me, but I’ll write about it))) But I have nowhere to go, so I’m writing here: How did I get rid of stretch marks after childbirth? I will be very glad if my method helps you too ...

The sun, which heats and illuminates our Earth, thanks to which the world is painted with different colors, radiates pure white light. But when we look at the sky, we see blue and blue colors. Why not white, since the color of the sun's rays was originally like this, but the air is transparent?

Why do we see blue skies?

White is made up of the seven colors of the rainbow. That is, white is a mixture of red, orange, yellow, green, blue, blue, purple. The Earth's atmosphere is made up of a mixture of gases. The sun's rays, reaching the Earth, meet with gas molecules. Here the rays are reflected and decomposed into seven colors of the spectrum. The rays of the red spectrum (this includes: red, orange, yellow) are longer, they, for the most part, pass directly to the earth, without lingering in the atmosphere. The rays of the blue spectrum (green, cyan, indigo, violet) are short-wavelength. They bounce off the air molecules in different directions (scatter) and fill the upper layers of the atmosphere. Therefore, the entire sky is permeated with blue light, spreading in different directions.

It is worth clarifying why we do not see the sky green, but we see it blue. This happens because the colors of the blue spectrum mix with each other and the result is a blue sky. Besides, human eye perceives blue color better than, for example, violet. Then another interesting point is why the sky is blue and the sunset is red. The fact is that during the day the sun's rays are directed perpendicular to the surface of the Earth, and during sunset and sunrise - at an angle. With this position of the rays relative to the Earth, they have to move in the atmosphere over long distances, so the short spectrum waves go to the sides and become invisible, and the long spectrum waves are partially scattered across the sky. Therefore, we see the sunset and sunrise in red-orange tones.

How to explain to a child why the sky is blue?

Now that we have figured out the color of the sky ourselves, let's think about how to make an explanation of the question why the sky is blue accessible to children. For example, you can do this: the sun's rays, reaching the Earth's atmosphere, meet with air molecules. Here the solar beam is decomposed into colored light waves. As a result, red, orange, yellow light continues to move towards the Earth, and the colors of the blue spectrum are retained in the upper layers of the atmosphere and distributed over the sky, coloring it blue.

Knowing your children and their level of knowledge about our planet, you will be able to understand how easier it is to explain to your child why the sky is blue.

“Dad, mom, why is the sky blue?” - how many times parents and the older generation hushed up when they heard a similar question from a small child.

It seems that people with higher education they know almost everything, but such an interest in children often baffles them. Perhaps the physicist will easily find an explanation that satisfies the baby.

However, "average" parents do not know what to say to the child. You need to figure out which explanation is suitable for children, and which for an adult.

To understand the blueness of the sky, you need to remember school course physics. Colors are distinguished by their ability to scatter (due to wavelength) in the gaseous envelope surrounding the Earth. So, the red color has a low ability, which is why it is used, for example, as external side lighting for aircraft.

Thus, those colors that have an increased ability to scatter in the air are actively used to mask any objects from air and ground enemies. Usually these are the blue and violet parts of the spectrum.

Consider scattering using the example of a sunset. Since the red color has a low scattering power, the departure of the sun is accompanied by crimson, scarlet flashes and other shades of red. What is it connected with? Let's consider in order.

We argue further. The blue and blue "branch" of the spectrum is between the green and purple flowers. All these shades have a high scattering power. And the maximum scattering of a certain shade in a particular medium colors it in this color.

Now we need to explain the following fact: if the purple hue is better diffused in the air, why is the sky blue, and, for example, not purple. This phenomenon is explained by the fact that the organs of vision of a person with equal brightness "prefer" precisely blue shades, not violet or green.

Who paints the sky?

How to answer a child who looks at the parent with enthusiasm and expects a clear and quite clear answer. The parent's departure from the question can offend the baby or dissuade him of the "omnipotence" of mom or dad. What are possible explanations?

Answer number 1. Like in a mirror

It is extremely difficult for a child of 2-3 years old to tell about spectra, wavelengths and other physical wisdom. But there is no need to dismiss it, it is better to give the maximum simple explanation, satisfying the natural curiosity inherent in a tiny child.

There are many bodies of water on our Earth: there are rivers, lakes, and seas (we show the child a map). When it is sunny outside, the water is reflected, as in a mirror, in heaven. That's why the sky is as blue as the water in the lake. You can show the child in the mirror any blue object.

For kids early age such an explanation can be considered sufficient.

Answer number 2. Spray in a sieve

An older child can be given a more realistic explanation. Tell him that a sunbeam has seven hues: red, orange, yellow, green, blue, indigo, and violet. At this point, show the drawing of the rainbow.

All rays penetrate to the Earth through a dense air layer, as if through a magic sieve. Each ray begins to splatter into its constituent parts, but the blue color is retained because it is the most persistent.

Answer number 3. The sky is cellophane

The air near us seems transparent, like a thin plastic bag, but its real color is blue. This is especially noticeable when looking at the heavens. Invite the child to lift his head and explain that since the air layer is very dense, it takes on a bluish tint.

For greater effect, take a plastic bag and fold it several times, inviting the child to see how it changed color and degree of transparency.

Answer number 4. Air is small particles

For kids preschool age The following explanation will do: air masses- this is a "mixture" of various moving particles (gas, dust, litter, water vapor). They are so small that people can see them special equipment- microscopes.

The rays of the sun include seven shades. Passing through the air masses, the beam collides with small particles, as a result of which all colors decay. Since the blue tint is the most persistent, we distinguish it in the sky.

Answer number 5. Short rays

The sun warms us with its rays, and they seem yellow to us, as in children's drawings. However, each ray actually resembles a bright rainbow. But the air around us includes many particles invisible to the eye.

When a celestial body sends rays to Earth, not all of them reach their destination. Part of the rays (which is blue) is very short and does not have time to get to the Earth, so it dissolves in the air and becomes lighter. Heaven is the same air, only being very high.

That is why when a child raises his head, he sees the sun's rays dissolved in the air above. That is why the sky turns blue.

It is very important for children to get a quick explanation, but it is not always possible to remember or come up with a simple and understandable answer. Avoiding the conversation - of course, not the most the best option developments, but it is still better to prepare.

Try to explain to the child what you will tell, but do it a little later. It is necessary to specify exact time, otherwise the baby will think that you are deceiving him. You can do the following:

Think of the planetariums, where experts explain the history of the appearance of the Earth in a very fascinating way, talk about the starry sky. The kid will definitely like this fascinating story. And even if the guide does not explain where the blueness of the sky came from, he will learn a lot of new and unusual things.
If it is not possible to go to the planetarium or the question remains unanswered, you will have time to search in any sources, for example, on the net. Just choose an explanation, focusing on the age and level of intellectual development of children. And do not forget to thank the child, because it is he who helps you develop.

Why the sky is blue? Similar questions worry many kids-why-why who get acquainted with the world around them. It is good if the parent himself knows where the blue above his head comes from. This will help our answer options.

Before you tell your version, invite your child to reflect and put forward their own idea.

In such a simple way, you can bring up an inquisitive baby who always strives to find an explanation for every fact that excites him.
