Cosmonautics is the process of exploring outer space with the help of automatic as well as manned spacecraft. This term was proposed by G. E. Langemak, who is one of the pioneers of Soviet rocket technology.

slide 3

On April 12, all of Russia celebrates Cosmonautics Day - the day of the launch of the Vostok spacecraft into low Earth orbit with the first cosmonaut Yuri Gagarin on board.

slide 4

On April 12, 1961, at 9:07 Moscow time, Yuri Alekseevich Gagarin launched from the Baikonur Cosmodrome, making the first space flight in the history of mankind on the Vostok satellite ship. Everyone remembers Gagarin's now catchy phrase: "Let's go!", which he uttered when he boarded the ship.

slide 5

The flight took place in near-Earth orbit at altitudes of 181-327 kilometers. In 108 minutes, the satellite with the world's first cosmonaut circled the globe and safely returned to Earth near the village of Smelovka, Ternovsky district, Saratov region.

slide 6

The orbital flight made by Yuri Alekseevich Gagarin on the Vostok 1 spacecraft was a powerful breakthrough in space exploration. By decision of the International Aviation Sports Federation since 1968, April 12 is celebrated as the World Day of Aviation and Cosmonautics.

Slide 7

GAGARIN Yuri Alekseevich (1934-1968) USSR cosmonaut, colonel, Hero of the Soviet Union, USSR pilot-cosmonaut The first person to fly into space. Born in the family of a collective farmer in the city of Gzhatsk, Smolensk region. In 1941 he began to study at a secondary school, but his studies were interrupted by the war. After the end of the war, the Gagarin family moved to Gzhatsk, where Gagarin continued to study. In 1951 he graduated with honors from a vocational school in the suburbs.

Slide 8

Gagarin was awarded the gold medal to them. K. E. Tsiolkovsky, de Lavo medal, gold medals and honorary diplomas of the international association "Man in Space" and the Italian Association of Cosmonautics, gold medal "For Outstanding Distinction" and an honorary diploma of the Royal Aero Club of Sweden, Large gold medal and diploma of the FAI, gold medal of the British Society for Interplanetary Communications, Galaber Prize for Astronautics. Since 1966 Gagarin was an honorary member of the International Academy of Astronautics. He was awarded the Order of Lenin and medals of the USSR, as well as orders from many countries of the world. He was awarded the title Hero of Labor

Slide 9

Gagarin died tragically in a plane crash near the village of Novoselove, Vladimir Region, while performing a training flight on an airplane (together with pilot Seregin). In order to perpetuate the memory of Gagarin, the city of Gzhatsk was renamed the city of Gagarin. Gagarin's name was given to the Air Force Academy (VVA).

Slide 10

Yuri Gagarin

He remained in the memory of his comrades in the first set of cosmonauts and everyone with whom he worked as a simple, accessible, wonderful person. And his sunny smile has been illuminating the way to the stars for mankind for almost half a century, since the day of the first space flight.

slide 11

On April 12, 1961, Yu. A. Gagarin made the first space flight in the history of mankind on the Vostok spacecraft. For 1 hour 48 minutes, it circled the globe and landed safely in the vicinity of the village of Smelovka, Saratov Region. After the flight, Gagarin continuously improved his skills as a pilot-cosmonaut, and also took a direct part in the education and training of cosmonaut crews. With the mission of peace and friendship, he visited many countries.

Spring is rich in wonderful holidays, but one of them is especially dear to the heart of Russians. This is Cosmonautics Day, which has been celebrated for more than fifty years. Traditionally, schools hold class hours dedicated to this day. Depending on the age of the students, the form of conducting is chosen, and certain tasks are formulated.

The main goals and objectives of the class hour

Choosing the purpose of the class hour, it is necessary to focus on the age of the students, the pedagogical validity of the event and the desired result. If we are talking about a classroom hour for elementary school (grades 3-5), goal may sound like this: creating conditions for enriching students' knowledge about the history of the Cosmonautics Day holiday.

In this case, this goal will be realized by the following tasks:

• Introduce students to the history of the holiday.
• To develop the cognitive activity of students, to induce further interest in the study of the event.
• Cultivate patriotic feelings.

For high school students, it is appropriate to choose more local goals, for example, those with a local history focus.

History reference

Class hour on the theme "Cosmonautics Day" must contain a mandatory block of historical events. The main thing that children should learn about is the event that took place on April 12, 1961. The first man flew into space. It was a citizen of our Motherland - Yuri Alekseevich Gagarin. He made his flight lasting 108 minutes on the Vostok-1 spacecraft.

A year later, on April 9, 1962, at the suggestion of German Titov, the second Russian cosmonaut, the Cosmonautics Day holiday was approved by the Presidium of the Supreme Soviet of the USSR.

By the way, German Titov was the second Soviet man to conquer space, and still remains the youngest cosmonaut to orbit the earth.

As of 2014, 558 people have been in space, 56 of them women. Our compatriot Valentina Tereshkova was also the first woman in space. She made her flight on June 16, 1963 on the Vostok-6 spacecraft.

A class hour about astronautics is an opportunity to instill in schoolchildren a sense of patriotism and pride in their people. After all, our compatriots were the first people to go into outer space. Alexei Leonov did it on March 18, 1965. Svetlana Savitskaya accomplished her feat on July 25, 1984.

It is necessary to discuss with high school students the gravity and danger of this profession. Since 22 cosmonauts died during the entire time of space flights, 5 of which were citizens of our country. The heroism and valor of these people is respected and admired, and the task of the teacher will be to instill these feelings in students.

Filling the class hour and decorating the office

In order for the event not to become a boring enumeration of facts, it is necessary to fill it with an entertaining and educational component.

The teacher needs to choose an epigraph that is suitable for the topic of astronautics and put it on the board. The statements of K.E. Tsiolkovsky, the founder of theoretical cosmonautics.

• "The impossible today will become possible tomorrow."
• « All our knowledge, past, present and future is nothing compared to what we will never know.”
• “It cannot be that there is not somewhere matter, time and space. They are infinite, continuous and eternal. It also cannot be that there is no life somewhere. It is also eternal, continuous and omnipresent…”

You can use the famous phrase uttered by Yu.A. Gagarin after landing.

The development of an extracurricular activity is a laborious task, so you can download a ready-made work from the site for free and engage directly in the preparation of a class hour.

Space books

In the office, it is worth making a small book exhibition of books, both artistic and scientific. Encyclopedias and atlases open on bright and memorable pages. You can use the following books:

• Galina Zheleznyak "Cosmonautics. Discovery of the Universe.
• Mark Garlick, The Illustrated Atlas of the Universe.
• Planets: a navigator for the young and brave.

Invite students to familiarize themselves with fiction about astronautics and adventures in space. For example:

• K. Bulychev "The Adventures of Alice";
• A. Ivanova, V. Merzlenko "Petya's extraordinary adventures in space", etc.

It would be appropriate to hang portraits of the first astronauts, a star map, images of spaceships in the classroom.

The whole event is best done against the background of music, light and unobtrusive. At the time when the students pronounce the material, the volume should be turned down.

It would be useful to use short fragments from Air Force documentaries about astronautics, to show the chronicles of the first flight of Yu.A. Gagarin.

The choice of the form of a class hour about Cosmonautics Day largely depends on the age category of students. The easiest way is to combine several forms into one, then the event will turn out to be rich and will definitely remain in the memory of the students.

For the primary school classroom hour, it is more harmonious to use the lecture form combined with the competitive form. Conduct a small quiz about space, ask riddles on the topic of astronautics.

Possible topics for class hours dedicated to Cosmonautics Day

For grades 1-5 of elementary school, it is better to choose simple and understandable topics. For example:

• "Forward to the stars!"
• "What is astronautics?"
• "Who is he, the first cosmonaut?"
• "The Path to Space"

For high school students, the following topics are suitable:

• "Preparing a person for space flight"
• "Secrets of the Starry Sky"
• "Heroic profession - astronaut"
• "The prospect of further space exploration"

When creating a presentation for Cosmonautics Day, several conditions must be met:

• brevity;
• information content;
• cognition;
• literacy;
• the presence of a visualized series.

You can use . This will greatly simplify the preparation of the teacher for the classroom.

To successfully complete the class hour, you need to conduct a reflection. This can be expressed in the form of a table that students fill out, in the form of a survey, in the form of a secret ballot, etc. After processing the results, it will become clear whether the initial goals were set correctly and by what percentage the tasks of the class hour for Cosmonautics Day were implemented.

During the classes

Leading:

In the minds of scientists for many years
There lived a cherished dream:
Take off with rockets
Into interplanetary space.

Leading:

Since ancient times, people have dreamed of taking to the skies. Even in fairy tales, these dreams came to life (flying carpet). People made wings for themselves, but all these experiments were unsuccessful. And so, the first planes appeared. The dream of the people came true. A man could take to the sky! He could fly!

Leading:

Living and believing is wonderful
Unforgettable paths before us
Astronauts and dreamers say
That apple trees will bloom on Mars.

Leading:

And so, this day has come, the usual spring day on April 12, 1961 was destined to forever enter the history of mankind. On this day, at 10:20 Moscow time, a spaceship, the Vostok satellite with a man on board, was launched from the Baikonur Cosmodrome. The cosmonaut pilot is Yu.A. Gagarin, a citizen of Russia.

Student:

Dawn. We didn't know anything yet.
The usual "breaking news":
And he is already flying through the constellations.
The earth will wake up with his name.

Cosmonautics Day is celebrated in Russia in accordance with the Decree of the Presidium of the USSR Armed Forces of April 9, 1962 in honor of the first space travel in the history of mankind by Yuri Alekseevich Gagarin on April 12, 1961: the orbital flight - one revolution around the globe - on the Vostok 1 spacecraft continued 108 minutes.

By decision of the International Aeronautical Federation (FAI), April 12 is World Aviation and Astronautics Day.

Leading: This is a national holiday.

Presenter: It seems familiar to us that spaceships start from the Earth. Dockings of spacecraft take place in high celestial distances

Leading: Cosmonauts live and work in space stations for months, automatic stations go to other planets

Presenter: Can you say "what's so special"? (Answers)

Leading: More recently, space flights have been talked about as science fiction.

Presenter: In our time, the flight of a spacecraft is considered commonplace.

Leading: And sometimes it even seems strange that a hundred years ago people could only dream of such flights.

Leading: A combat mission was successfully launched from the new Baikonur cosmodrome

Presenter: intercontinental

Leading: multi-stage ballistic missile "R-7"

Leading: On April 12, 1961, for the first time in the world, the first cosmonaut of the planet flew on the Vostok spacecraft.

Presenter: It was our citizen Yuri Alekseevich Gagarin.

SLIDE 9 "Song"

Leading: The inhabitants of the Earth will always remember with gratitude the names of people who opened a new sphere of human activity.

Presenter: In this constellation of names, one of the brightest is the name of the first cosmonaut of the planet, Yuri Gagarin, and the name of the chief designer, Academician Sergei Pavlovich Korolev.

Leading:

The world held its breath. The world listened to a man flying over oceans and countries, and people in these countries repeated the words: "Gagarin, Yuri, Russia." The earth recognized the man who paved the way to the stars. He became the hero of the whole earth. So the word "astronaut" appeared.

Student:

Astronaut. There was no such word
Among many, many thousands of words.
Brought him to earth from the sky
Pilots Gagarin and Titov.

Student:

We live on our planet
In such a wonderful age!
And the first of the first in the rocket,
Soviet man flies!
Not for the purpose of military intelligence,
On a super speed ship
He flew alone in the universe,
To return to Earth again!
Not in vain skillful hands have worked
For the glory of the people, for the glory of the country!
Working people of science
Commonwealth peaceful strong!

SLIDE 13 (during the words)

It took only 45 minutes to circle the Earth. But how long did it take to prepare for this flight! How many people worked on the creation of the rocket. Chief designer - Sergei Pavlovich Korolev. No one knew his name, although he did a lot for modern space flights. Yuri Alekseevich Gagarin paved the way to the stars. He was the first, which is why he is called the pioneer of space.

SLIDE 14 (during the words)

Student:

When he returned to earth,
Having finished stellar affairs,
So white-toothed smiled
The smile was so warm!

There is only kindness and strength in it,
There is not an ounce of superiority.
As if the grove radiated
Birch lake light.

She united wisely
Movement of will and mind.
So sunny frosty morning
Laughing Russian winter.

She, like a miracle, opened up to us,
And such was its scope,
Such sincerity shone
In slightly squinted eyes!

It is easy for us on the great path,
The soul is warmer in her warmth.
Yes, without Gagarin's smile
It would be darker on Earth!

But most of all, his own mother was waiting for him. This is her name Yuri Gagarin repeated in space. How proud she was of her son.

Here it is, it's a miracle!
: Mother is coming - step aside people:
The son returned, and from where -
From the very heights of space!
He broke into our tomorrow,
What is fantasy itself to match:
The first astronaut in the world
Hugs and kisses his mother.
And with the same maternal strength,
Sharing the joy of the people,
The whole of Russia embraces the son,
The whole Earth applauds the son!

SLIDE 16 and 17 (during the words)

Leading:

Space flights have begun. June 16-19, 1963 The first joint flight was performed by Valery Bykovsky and Valentina Tereshkova, the first female cosmonaut. She flies over the globe, and her distant call signs sound to the whole world: "I am the Seagull!".

Student:

"I am the Seagull" is heard again
Above the stars.
And what is the name of this "Seagull"?
Yes, just Valentina.
Rudders obey her
And the engines are formidable,
And miss the daughter of the Earth
All traffic lights are stellar.

Leading:

Years have passed. Hundreds of astronauts have been in space. You can even fly with a tourist package.

Orbital stations fly around our Earth - experimental laboratories that make it possible to predict the weather and find minerals. And the boys, as before, dream of becoming astronauts.

SLIDE 19 (during the words)

Student:

You wait for us stars when we grow up,
We will come to you and tell you about
About how beautiful the planet Earth is,
What cities and fields are on it,
What flowers and trees grow
What birds sing in the forests.

Student:

We will also tell about our childhood,
About our Motherland, in which we live.
About summer hikes in fresh dew,
About wet stones on a sandy spit.

Student:

You hurry guys to your class,
Without study, things will not go -
Astronauts grow up among us
But without knowledge they won't take you to Mars!

Leading:

And now let's check if you are ready for a space flight (split into two teams, and choose a name for your ship).

Leading:

Now let's do an interview. What do you think astronauts should be like? (Brave, hardy, resourceful, inquisitive, hardworking, quick-witted.

April 12 Cosmonautics Day Kravtsun M.G. primary school teacher MBOU ESOSH No. 1 village Egorlykskaya Rostov region

On one of the spring days 53 years ago, an unusual event for those times took place: on April 12, 1961, Yuri Alekseevich Gagarin made the first space flight in the history of the Earth on the Vostok spacecraft. Since then, every year on April 12, our country celebrates Cosmonautics Day. This is a holiday for cosmonauts, scientists, engineers, workers who invent and make rockets, spacecraft and satellites.

People have long dreamed of exploring outer space. They thought for a long time about how to build a spaceship to fly above the stars. People dreamed of knowing the sky, and not just setting altitude records. New thousands of inventive minds and new hundreds of thousands of skillful, talented hands joined the common work... And so they created spaceships and flew into space. But before the famous cosmonaut Yuri Alekseevich Gagarin flew

On November 3, 1957, a living heart began to beat in the lifeless, cold, always black space of space. In the hermetic cabin of the satellite, the dog Laika lived, breathed, and flew over the world.

Following Laika, Belka and Strelka followed. Guinea pigs, monkeys, parrots, mice, rabbits also flew - all of them honestly served a great dream.

Yuri Alekseyevich Gagarin

Our hero was born on March 9, 1934 in the village of Klushino (now the Smolensk region). By origin, he is a peasant. His mother Anna Timofeevna and father Alexei Ivanovich were simple workers of their time. The childhood of the future cosmonaut passed in his native village, here he went to school, where he had to suspend his studies in 1941 due to the German occupation. Two years later, in 1943, school attendance resumed. In May 1945, Yura and his family moved to the city of Gzhatsk, where in May 1949 he graduated from the sixth grade of high school. After school, he entered the Lyubertsy vocational school and at the same time the school of working youth. Yura graduated from college with honors. In 1951, Gagarin entered the Saratov Industrial College, and in October 1954 for the first time he came to the Saratov flying club. In 1955, he successfully completed his studies and made his first flight on a Yak-18 aircraft. He served in the army, which began in 1955, in the city of Chkalov (now Orenburg), in the 1st Military Aviation Pilot School named after K. E. Voroshilov. Despite the difficulties during his studies, Yura graduated from college with honors. Then for two years he served near Murmansk in the 169th Fighter Aviation Regiment of the 122nd Fighter Aviation Division of the Northern Fleet, armed with aircraft. On December 9, 1959, Gagarin wrote a statement in which he asked to be admitted as a candidate cosmonaut. And a week later he was called to Moscow to undergo a medical examination. He was qualified! And on March 3, 1960, he was enlisted as a candidate cosmonaut. Since that time, regular training began.

What should an astronaut be like? Bold, determined, collected. And his health must be very strong: after all, during takeoff and landing, the astronaut experiences the strongest overloads. And in space, he will be in a state of weightlessness - the test is not easy. In order to determine whether astronaut candidates meet all the necessary requirements, they are examined for a long time and carefully by a medical commission. They even conduct such an experiment: they put a person in a special centrifuge, and for some time he rotates in it. If the body copes with this task, it means that a person will feel normal in space. And after long tests and discussions, a decision was made: Yuri Alekseevich Gagarin would become the first cosmonaut in the world. Finally the decisive day arrived. April 12, 1961 Yuri Gagarin on the spacecraft "Vostok" made a space flight. In 108 minutes, the satellite with the world's first cosmonaut circled the globe and safely returned to Earth. It was a powerful breakthrough in space exploration! And then there was a solemn meeting on Red Square. In a few hours, Yuri Gagarin became the most famous person in the world. When the government announcement of the great flight was heard on the radio, the streets of the whole country filled with crowds of people. Everyone wanted to greet the world's first cosmonaut, the Son of the Earth, the Citizen of the Universe.

But space isn't just for men.

Valentina Vladimirovna Tereshkova (1937) - cosmonaut, the first woman to travel in space. She was born on March 6, 1937 in a small village in the Yaroslavl region. Education in the biography of Valentina Tereshkova began in 1945 at the Yaroslavl school. After seven years of school, she began working at a factory, and at the same time she studied at an evening school. The next educational step in Tereshkova's biography was the technical school of light industry. Simultaneously with her studies there, Valentina worked at a textile factory. In 1962, she became one of the contenders for the candidacy of the first woman to go into space. She went through a lot of training - parachuting, weightlessness, resistance to flight. On June 16, 1963, on the Vostok-6 spacecraft, Tereshkova made the world's first space flight by a female cosmonaut, spending almost three days in orbit. Valentina hid her preparations for the flight from her relatives so as not to disturb them. On the day of the first flight into space, she said that she was leaving for the skydiving competition, they learned about the news on the radio. Since 1966, he has been active in state activities. She was a people's deputy of the USSR, chairman of many Presidiums. Since 1963 he has been an Honored Master of Parachuting. The chronology of military ranks in the biography of Valentina Tereshkova is as follows: lieutenant, captain - 1963, major - 1965, lieutenant colonel - 1967, colonel - 1970, major general - 1995. She retired in 1997. She has many awards, orders, medals.

He is the first cosmonaut in the world, Because he is a hero for everyone. He was the kindest person, He was with an unearthly smile. That's why this holiday has become kind for the kids, Because, you see, about space Everyone thought in childhood: They look like Gagarin All the boys want to be, In honor of him, children draw A multi-colored starfall. In honor of Gagarin - avenues, Ships and boats ... Now the holiday of astronauts: Cosmonautics - "Hurrah!". Cosmonauts Day Both boys and girls, Waking up and in good dreams, Everyone dreams about space, About distant skies. Today is the holiday of astronauts! - Congratulations on this day. Gagarin opened it to us. Much has been said about him.
