That's right, today I will tell you about the Sun and its importance for life on Earth, how it warms during the day and how our ancestors treated the sun.

V. Learning new material

1. Game “Gifts of the Sun” (reception “Associative Bush”)

There is a big sun on the board. Children must name what the sun gives to the earth (warmth, light, energy, life, beauty, etc.). Write down all the words the children name on the rays of the sun.

2. Brainstorming technique

What do you know about the Sun?

What nature is the sun?

Does wildlife need it?

What do we get from the Sun?

– We’ll also show you how they sit down.

– The wings folded back.

3. Teacher’s story with elements of conversation

1) The sun and animals (during the story, the teacher shows subject pictures)

M. Prishvin wrote: “Everything beautiful on Earth comes from the Sun...”

For the inhabitants of planet Earth, sunlight and warmth are of great importance. The sun warms and illuminates the Earth. Thanks to this, animals see the light around them.

Do all animals need sunlight?

What about those animals that don’t have eyes?

Do all animals need sunlight?

The fact is that the sun's rays help produce very useful substances in the body of animals - vitamins.

M. Zverev talks about how badger cubs sunbathe: “The badger cubs’ hole is near a small clearing. As soon as the earth warms up, the badger takes all her cubs out into the sun. The little badgers fuss around in the clearing for a while and fall asleep, warmed by the sun. As soon as a fresh breeze blows, they begin to squeak in displeasure. Mother badger drags everyone into the hole. The wind calms down, and the badger has work again: drag the badgers, one by the collar, into the clearing.

Insects, snakes, and lizards love the warmth of the sun. It makes them agile and fast.”

G. Skrebitsky says: “You are walking along a forest edge or along a ditch. Carefully inspect each large stone. The stones became so hot in the bright sun that my hand felt hot. Look: there is a lizard lying on the stone. She spread her body, spread her paws wide, and closed her eyes. She recently woke up from hibernation in an earthen hole. I woke up and went out to bask in the sun. The lizard will warm up, become fast and agile, and start hunting. Beware of flies, slugs and other small animals!”

Have you ever seen anything like this in the spring?

Is it possible to catch animals and take them home?

2) Sun and plants

Solar heat and light are necessary not only for animals, but also for plants.

They grow, bloom, produce fruits and seeds in warm weather. In winter, plants sleep.

On a hot summer day, when the sun burns mercilessly, animals can hide in the shade. And plants have nowhere to run and hide. So they cover their leaves with a thick layer of wax or white hairs, or curl the leaves. Wax and hairs protect the leaves from burns.

If animals can live without sunlight in caves and underground, plants cannot live without sunlight.

Look at these two indoor flowers. Compare, one of them lacked sunlight. Tell me what it looks like.

Remember your walks on the street, did you have to move a large stone from the ground or lift a board from the grass that had been lying there for a long time, do you remember what the plants looked like under them? Tell us about your observations.

The thing is that the Sun helps the plant to feed. How does this happen?

Listen to a fairy tale about this: “Little wizards live in the leaves of plants - chlorophyll grains. They are so small that they can only be seen under a microscope. Their color is bright green. And the leaves of plants are green because there are a lot of these chlorophyll grains. Early in the morning, as soon as the Sun reaches out its rays, the wizards wake up - chlorophyll grains. And they immediately get to work.

The roots are ordered: “Roots, roots, take water from the ground.” The stems are given the command: “Stem, stem, give water from the root to the leaves.” The leaf is punished: “Leaf, leaf, open your pores, give us air. Then the green wizards take the sun's rays. Rays mix water and carbon dioxide, which was taken out of thin air. And what a miracle! Sugar and oxygen are formed from water and carbon dioxide. The roots, stems, leaves, fruits, and seeds feed on sugar. They eat sugar and grow. Oxygen, which is necessary for everyone to breathe, is released into the air by chlorophyll grains. After all, they also need to settle accounts with the air.

All day long, green wizards mix water and carbon dioxide with sunlight, feeding plants and improving the air. The sun goes to bed, and it’s time for the chlorophyll grains to rest. We must thank them for cleaning the air and feeding the plants.

And just think, before you pick or spoil a plant leaf, how many magic seeds you can destroy!

Children, did you like the fairy tale?

Why do plants need sunlight?

Conclusion: in nature, everything begins with the Sun, which sent its golden warm rays to the damp earth and awakened all the blades of grass, blades of grass, bushes and trees to life. Under this gentle warmth and light in the clean air, they grew and provided food for all the herbivores. These, in turn, provided food for small predators, which feed on larger predatory animals and birds.

3) The sun and man

Today we talked a lot about how both plants and animals need sunlight and warmth.

Are they necessary for humans?

For what?

Remember the fairy tale by K. Chukovsky “The Stolen Sun”

What happened on Earth without the Sun?

Is life possible on Beseda Earth?

Ø Name the sunniest month of the year.

Ø The sunniest flower?

Ø The sunniest event in a person's life?

Ø The sunniest animal? Insect? Bird?

Ø Sunniest quality?

7. Teacher's story

For a very long time people have considered the Sun to be holy and righteous. The sun warms the ground into which the grain is thrown, a green stalk reaches towards the Sun, and under the sun it turns into an ear of bread. Ancient man imagined the sun in the form of a fiery wheel that rolled from the sky. And the life of all living things depends on this solar path in the sky. The sun was revered by everyone - both children and adults. It was considered a sin to point a finger at the sun, spit in the direction of the sun, and throw stones.

There are many fairy tales, miracles, and beliefs associated with the Sun.

Children call an insect (ladybug) “sun”. When clouds appear in the sky, they sit the ladybug on the palm and say:

Sunshine, sunshine, look out the window,

There your kids are asking for candy!!!

If a ladybug rushes up, the sun will soon come out, and if it just spreads its wings a little, then the clouds will cover the sun.

Sunflower brought from distant sunny lands became a symbol of Ukraine. People believed that this plant constantly turns after the sun, because it is afraid that the luminary might get angry and leave the Earth forever.

Old people say: “As long as the golden star shines in the pure blue, so long will the earthly paths continue.”

Look at the picture in the textbook on p. 37

What is bigger – the Sun or our planet Earth?

Remember the beginning of our lesson. Life on Earth without the Sun is impossible: if the Sun stops shining, then green plants will die, since they cannot live without heat and light; animals and people will have nothing to eat. All living things will freeze from the unbearable cold. However, this will not happen, since the Sun is a star that emits a lot of heat and light into space. Its diameter is 109 times larger than the diameter of the Earth, but in the sky we see the Sun small, since its distance from the Earth is 150 million km. The temperature of the solar surface is 6000 degrees, and near the center - 15 million degrees. Scientists have calculated that the Sun will continue to shine for billions of years. So you and I have nothing to fear.

- I'm Sunny...

The sun plays a very important role in the life of our planet. It is the source of light and heat on Earth. Evaporation of water, precipitation, flow of rivers, storms, thunderstorms, droughts and all other phenomena that determine the climate and weather on Earth depend on the heating of the Earth by the Sun and change depending on the changes occurring on the Sun.

So, according to V.I. Vernadsky, the most significant feature of the biosphere is the biogenic migration of atoms chemical elements, caused by the radiant energy of the Sun and manifested in the process of metabolism, growth and reproduction of organisms Vernadsky V.I. Biosphere ( selected works in biogeochemistry). M., 1967. - pp. 56-61. .

A unique type of cycles in the biosphere includes its rhythmic changes. Rhythm is the repetition in time of a complex of processes that each time develop in the same direction. At the same time, two of its forms are distinguished: periodic - these are rhythms of the same duration (the time of the Earth's rotation around its axis) and cyclic - rhythms of variable duration. Periodicity in the biosphere is manifested in many processes: tectonic, sedimentation, climatic, biological and many others. Rhythms come in different durations: geological, secular, intra-century, annual, daily, etc.

Some rhythms are associated with uneven irradiation of the Earth due to its movement around the Sun. Changes in the timing of the equinoxes, the inclination of the axis of rotation to the ecliptic and the eccentricity of the earth's orbit correspond to periods of about 21,000 years, 40,000 years and about 92,000 years. These periods, identified by the Yugoslav scientist M. Milankovich, could serve as the cause of climate fluctuations. See for more details: Voitkevich G.V., Vronsky V.A. Fundamentals of the doctrine of the biosphere. M., 1989. P. 108..

Solar radiation is the energy of solar radiation entering the Earth in the form of a stream electromagnetic waves. The sun emits powerful electromagnetic radiation around it. Only one two-billionth part of it enters the upper layers of the Earth's atmosphere, but it also amounts to a huge number of calories per minute.

Not all of the energy flow reaches the Earth's surface. Most of it is thrown away by the planet into outer space. The Earth reflects the attack of those rays that are destructive to the living matter of the planet. On their further path to Earth, the sun's rays encounter obstacles in the form of water vapor filling the atmosphere, carbon dioxide molecules and dust particles suspended in the air. The atmospheric “filter” absorbs a significant portion of the rays, scatters them, and reflects them. The reflectivity of clouds is especially high. As a result directly earth's surface receives only 2/3 of the radiation that is transmitted by the ozone screen, but from this part much is reflected in accordance with the reflectivity of various surfaces.

The entire surface of the Earth receives just over 100 thousand calories per 1 cm2 per minute. This radiation is absorbed by vegetation, soil, and the surface of seas and oceans. It turns into heat, which is spent on warming up the layers of the atmosphere, moving air and water masses, to create all the great diversity of life forms on Earth.

Solar radiation reaches the earth's surface in various ways:

1) direct radiation: radiation received directly from the Sun, if it is not covered by clouds;

2) scattered radiation: the flow of radiation from the sky or clouds scattering the sun's rays;

3) thermal radiation: radiation comes from the atmosphere, heated as a result of exposure to radiation.

Direct and diffuse radiation arrives only during the day and together they make up the total radiation. Ta solar radiation, which remains after loss by reflection from the surface, is called absorbed. Solar radiation is measured with an actinometer.

Cosmic rays -- a stream of particles high energies, falling to the Earth from all sides. Nuclear reactions V high layers atmospheres are caused by cosmic rays not of solar, but of galactic origin. And yet, the intensity of these cosmic rays associated with solar activity: the more sunspots on the Sun, the weaker the flow of cosmic rays. This connection is carried out by the solar wind.

The solar wind at a distance of about 1013 m, i.e. at a distance of about fifty radii of the earth's orbit, compresses the lines of force of the galactic magnetic fields. For more details, see: Byalko A.V. Our planet Earth. M., 1989. P. 133.. Cosmic rays propagate mainly along magnetic field. Only the most energetic cosmic ray particles from the Galaxy can penetrate deep into this magnetic bubble around the Sun. The solar wind travels the distance to its border in six months to a year. When the Sun is calm, the solar wind is weaker, the boundary of the solar magnetosphere moves closer and becomes less dense. As a result, the intensity of cosmic rays reaching the Earth and the proportion of 14C in atmospheric carbon dioxide increase.

Thermal radiation from the Sun is constant. Solar activity changes only the short-wavelength, non-thermal part of the radiation at wavelengths less than 100 nm. This region, however, accounts for less than 1% of the Sun's total luminosity. The short-wavelength portion of solar radiation does not penetrate the upper layers of the earth's atmosphere. That's why solar activity practically does not change the heat flow coming to our planet, and has almost no effect on the Earth’s weather. Variable short-wave radiation from the Sun significantly changes the state of only the outermost shell of the Earth's atmosphere.

Both winds and currents are caused by radiation from the Sun hitting the Earth. It gives energy to the movements of the atmosphere and ocean. This energy dissipates and turns into heat, and friction forces actually arise. However, these forces are internal. For each such force that slows down the rotation of the planet, according to Newton’s third law, there is an equal and opposite force that accelerates the rotation of the Earth. The total moment of all internal forces is zero. Solar radiation does not change the angular momentum of the Earth; winds and currents, on average, do not slow down the Earth or accelerate it.

Every person has sometimes thought about what role the Sun plays in the lives of people on Earth. The sun is big star, which is located closer to us than all other celestial bodies, and thanks to it the origin of life on Earth began. If we look into the past, we remember that the Sun was considered the main deity. People at all times realized that it is thanks to sunlight that life exists on Earth.

Today, pride has so eclipsed the imagination of people that it does not allow them to think about the importance of the Sun for humanity, and most of the representatives modern society They think that they are the “crowns of nature.” And at the same time, they don’t even think about the fact that they may be deeply mistaken, since at one fine moment, nature may take cruel revenge. The time will come when our Sun will cease to exist and, at the same time, all life on Earth will die. People will forever lose the opportunity to admire the sunrise.

The sunrise and sunset times for any date can be calculated using the online calculator here.

Let's figure out what the significance of the Sun is for life on Earth? WITH scientific point From our point of view, all actions that take place on Earth are in one way or another subordinate to the Sun. And to be more specific - solar energy. The sun acts on the gaseous atmosphere that surrounds the entire globe as a result of which we can observe different natural phenomena in the form of precipitation, wind or fog. Large quantity sediment is stored in reservoirs, from where, with the help of hydroelectric power stations, the energy that the Sun used to lift water into the atmosphere is extracted.

The importance of the Sun for life on Earth is important not only for animals but also for plants. Thanks to vegetation, the air on Earth is constantly purified and to some extent resembles a small plant for converting carbon dioxide into oxygen. This can be explained very simply. The leaves contain chlorophyll grains, which, in the process of absorbing sunlight, produce oxygen.

The following example, which once again proves to us the need for solar energy. This is the combustion process that occurs in furnaces, which causes the burned-out carbon of plants to recombine with oxygen, resulting in the release of energy spent on the decomposition of carbon dioxide.

Is there a replacement for solar energy, because at night, before sunrise, energy is not generated, and if the Sun suddenly goes out, humanity will perish?

It is worth noting that the Sun is the main source of energy for industrial development. Since coal and oil are also of organic origin. As for the animal world, here our own strength is also maintained thanks to the accumulated solar energy in plants.

In addition to the Sun, there is another powerful source of energy - intra-atomic energy. On at the moment, it is not yet available to us and is in the process of research. The time will come when humanity will have the opportunity to test it, after which we will receive a second powerful source of energy, along with the Sun.

The importance of the Sun for life on Earth

Linda Bee__ Student, closed 4 months ago

Ti@na Master 3 years ago

Even in ancient times, people realized that without the Sun there would be no life on Earth. The ancient Greeks called the Sun the god Helios, the Romans called the radiant Apollo or Phoebus, and our Slavic ancestors called the god Yarila.

The sun is the powerful source of life on Earth. Without sunlight and warmth, not a single living creature - neither man nor animal - could live. Cold or warm weather, snow or thaw, drought or rain - all this is caused by an increase in summer or decrease in solar heat in winter.

Scientists estimate that the Earth receives one two-billionth of the heat emitted by the Sun. Some of this heat is reflected from the ice back into space. You probably know that large masses of ice are found in the north and south of our planet: in the Arctic and Antarctica.

Solar heat goes to warm the earth's surface. Without this, our planet would freeze and become cold. As the earth's surface heats up, it gives off some of its heat to the surrounding air ocean - the atmosphere. Winds blow in the lower part of the atmosphere.

Imagine that some powerful force has bound the air, making it unable to move. There would be no wind on the entire Earth, no wild gusts of a hurricane, not even easy breathing air. What would happen then? The great water cycle in nature would stop, rivers and streams would dry up, the grass in the meadows would dry up, the grain in the fields would dry up, the forests would turn yellow and dry up. The entire landmass would turn into a great desert.

You have lunch: eat cabbage soup with cabbage, fried potatoes for main course, and a slice of watermelon for dessert. It was the sun's rays that helped the plant create nutrients. Without plants there would be no animals or people on Earth. Plants are firewood, peat, coal.

If the Sun suddenly died out, people could survive for several decades due to the solar heat accumulated by plants. Then life would stop. But the Sun has existed for a long time and will exist for billions of years. The sun is the most powerful and durable machine that provides the heat necessary for life on Earth.

The meaning of the Sun tattoo

Today in tattoo parlors you can very often see an image of an independent or composite image of the sun. This is largely due to the fact that the meaning of the “Sun” tattoo is ancient tradition and a very rich history.

Almost all peoples have a cult of this heavenly body and the deity that personifies it in their culture. They also worshiped the solar circle itself, which had a deep magical tradition.

This is largely due to the fact that the sun is a source of heat, light and fertility for everyone on earth. It gives life to all living things on Earth. Some peoples still maintain the cult of the sun.

The first image of the sun can already be found in rock paintings primitive people. That is why such a tattoo can rightfully be called one of the most ancient. It is suitable for both men and women, reflecting one or another meaning in the context of the image.

In many ancient pantheons, the image of the sun occupies a very high and important place. Almost all calendar systems known to mankind are associated with this symbol. All world cultures have legends that tell about the appearance of the sun, as well as the nature of the sunrises and sunsets of this luminary.

In Egypt, the sun was considered the patron saint of the pharaohs. His incarnation was the supreme god Ra. Such a solar deity had extraordinary power and the ability to see everything.

The ancient Slavs worshiped the sun, considering it a symbol of wisdom and supreme power. Among the Slavs, the sun was represented in the image of the god Khors, riding across the sky in a gilded chariot. By the way, the tradition of eating pancakes is also closely connected with the worship of this luminary.

The ancient Celts attributed the meaning of this type of tattoo to the symbolism of eternity and the unity of heaven and earth. They depicted the sun, woven from tight knots, in bright tongues of flame.

The sun was very popular in ancient civilization Aztecs. There, the meaning of the “Sun” tattoo symbolized the power of pure spirit and freedom. Even blood sacrifices were made to him. The solar cult was closely connected with the timekeeping system. U Christian religion the sun was also associated with higher powers. The sun personified the life of a righteous man and acted as a symbol of Jesus Christ. The Word of God was also depicted using this symbol - it personified God's truth.

In the Shinto culture of Japan, the sun was embodied in the goddess Amaterasu, who was also the patroness of women and snakes. In Jewish culture, among the Greeks, among the Maoris of Australia, the sun always acts as an all-seeing eye, from which no one can hide. Therefore, it also becomes a symbol of a fair trial.

This tattoo has only positive meaning. It suits a person with a broad and kind soul. Depending on the theme of the plot, such a tattoo can be chosen for both men and women. The image can be large, located on the back, or it can be smaller. In this case, it is usually applied to the shoulder or chest.

In any case, the meaning of a tattoo of this type will speak of a person with a bright and righteous soul. It is believed that such a tattoo will be an excellent amulet that protects its owner from troubles and will bring him good luck and happiness.

What is the significance of the Sun for all living things? You will learn from this article.

What is the significance of the Sun for the Earth?

The sun is a huge star. And it is closest to our planet. It has long been proven that the life activity of all living organisms, including people, depends directly on solar energy. All processes that occur on Earth are subject to its influence.

The sun is heating up earth's crust. And solar radiation entering the planet is the main climate-forming factor. Direct rays of the Sun heat the surface of the earth, and it releases the resulting heat to the atmosphere. Different parts of the planet do not receive the same amount of radiation. And if it were not for the hot Sun, living organisms would not be able to live on the planet due to the very low temperature.

In addition, our star has a significant influence on the earth’s atmosphere. Thanks to this, we observe a variety of natural phenomena. The phenomena that occur on earth thanks to the Sun - rain, fog and snow could not occur without the beneficial influence of solar energy.

Plants and animals also exist only thanks to the energy of the warm star. Vegetation provides us clean air. And it is saturated with oxygen through the interaction of chlorophyll (found in green leaves) with the sun's rays.

Also the Sun is main source energy, which is necessary for the development of industry. Under its influence, oil and coal are formed. Animals also maintain their strength by eating plants with stored solar energy.

The influence of the Sun on humans

The energy of the luminary has a beneficial effect on the human body.

The sun is our eternal engine, which will work for many billions of years. It is known that only a small part (about one billionth) of the Sun's energy falls on our Earth. Nevertheless, this energy is enough to support life on Earth

What does history say?

Even before our era, people knew about the importance of the Sun for our planet. True, then no one imagined how much our planet depends on it. Residents of different states called the Sun differently: some as God, and others as holy power.

Positive sides of the sun's rays

The sun's rays perform many duties on our Earth, and the main ones are:

• Photosynthesis process
• Ideal temperature to support life

Photosynthesis is a process that occurs in plants. Every plant on Earth carries out this process without stopping, namely, it receives portions of rays from the Sun and, with their help, absorbs carbon dioxide and releases pure oxygen. Therefore, everything we breathe is the production of sunlight and plants.

Also, the sun's rays help maintain the temperature for the life of organisms. If the rays of the Sun did not fall on the Earth, then there would be hellish cold on the planet and no organism would be able to live even ten minutes.

And, of course, light. The sun illuminates our planet, and due to this we see everything that happens around us. Some would object: the Sun doesn’t shine at night, and everything is still visible, although not as good as during the day. There is a clear answer to such an objection: at night our planet is illuminated by the Moon, but without the Sun the Moon would not shine! That's right, the rays of the sun fall on the moon, and it, in turn, reflects these rays onto our planet.

Negative sides of the sun's rays

What are the downsides to the sun's rays? None, except radiation rays that can destroy the Earth in a few minutes. However, our planet is covered with an ozone layer, which protects it from the effects of radiation rays from the Sun. Scientists assume that the Earth's ozone layer will someday be destroyed and all life on Earth will die, but this will not happen soon, perhaps after several billion years. Therefore, we can say that there are no negative aspects to the sun's rays.
