Presenter 2. Today we have a physics holiday at school.
Lead 1.
The world is not easy, not easy at all
In everything there is a mystery, a riddle, a question!
Moments fly, years fly
You have to learn everything and always!
Everything in the world is around us
We wanted to understand immediately.
Everything that we study with you,
Connected, connected with life itself!
Lead 2.
The world is not easy, not easy at all
A mystery, a riddle, a question will surrender!
Sound or movement, light or darkness
The task is set by nature itself!
Presenter 1. Of course, you guessed that all these secrets are revealed to us by the wonderful science of physics!
Lead 2.
Have you heard the news?
Yesterday the State Duma considered the laws on pensions, on land, Newton's 1st, 2nd, 3rd laws.
So what?
Newton's first law was adopted in the second reading, the rest were sent for revision.
Yes, it was inconvenient with old Newton.
By the way, do you remember the story of how the law of universal gravitation was discovered?
Of course we remember. And what?
It's all nonsense.
Why?
Yesterday, for the purpose of the experiment, apples of different varieties and sizes were thrown on my head, but clever thoughts did not appear.
Teacher. Holiday rules.
Do not shout, the answer will not count.
Think first, then answer.
Answered correctly - get a token.
The one with the most tokens wins.
The winner will receive a prize.

Teacher. Well done. Well done.
Now we're going to watch a little scene. Your task is to carefully monitor the characters and what they say. You must correct them.
scene
Several students come out and talk about how tired they are of physics: either they will ask an essay about what light is, or they will ask a difficult problem.
First student.
I'm going to study at Moscow State University,
And become a famous journalist.
Tell me I won't take it
Where can physics help me?
Second student.
And I won't even teach it.
My dad will give me a share in the business.
And I will quickly forget school.
The laws of physics are ballast for us.
Lead 1. Years have passed.
The whole student, hung with cameras, comes on stage, promising to become a journalist. The editor sits at the table. There is a sign on the table.
Editor . Got a report?
Journalist. Brought. (Submits the manuscript. The editor reads it.)
Editor. What did you write? "The driver abruptly pressed the brakes, and the train stopped dead"
Journalist. Why not?
Editor . And this? “The ship sailed past me, and I admired the red line beautifully shimmering under the clear water, stretching along the entire board of the ship.”
Journalist. But doesn't that happen?
Editor. Listen! "The light, born in the depths of the moon, beckoned and beckoned to where it came from." How many classes did you complete?
Journalist . 11 classes and the faculty of journalism.
Editor. Did you sleep in physics class? And what's that? “The subtle squeak of a mosquito, published by its thin vocal cords, prevented me from falling asleep.” You can't give it to the press: they will make fun of us, You don't know physics at all, and biology, We have a serious journal, and there is nothing to do here without knowledge of physics! Look for a job in some cheap newspaper! (They leave).
Teacher. What didn't the editor like?
1. The train, due to its inertia, cannot stop instantly. 2. Waterline cannotbe underwater. 3. The light of the moon is not born in its bowels. The moon shines by reflected sunlight. 4. The squeak of a mosquito is created by the vibrations of its wings, not by the vocal cords.
Teacher. We continue to follow the heroes of our scene, years later.
Sitting on a chair and playing with mobile phone who wanted to become a businessman. His daughter comes up to him and asks for help to complete a difficult task in physics.
Girl. Dad, you are so cool, why don't you do homework with me? Did you study poorly?
Father. What are you? I was the best student!
Girl. And in physics?
Father . By itself!
Girl. Then help me answer physics questions.
Father. Let's.
Girl. Who first measured atmospheric pressure?
Father. Newton, of course!
Girl. Does water boil at 80 degrees in the mountains or in the valley?
Father . Water everywhere boils at 100 degrees!
Girl . Why don't air molecules fall to Earth?
Father .Because they are very light.
Girl. Is it easy to breathe on Everest?
Father. At any resort it is easy to breathe.
Girl .What is a vacuum?
Father. There is a vacuum cleaner.
Girl. What does a barometer measure?
Father. Judging by the name, it is connected with the bar, which means volume.
Girl . Everything. Thank you daddy, you are so smart!
Lead 1. The next day.
Dad is sitting right there. A girl approaches him.
Girl. What did you say to me! You have dishonored me! I was made fun of in class. You know nothing
Teacher "What did the businessman not know?" Who can give the correct answer? (Students give correct answers.)
We continue the holiday.

Sections: Extracurricular work
1 The facilitator starts in the background of the slides (Attachment 1)
"In a certain kingdom, in a certain state, there lived a man. The name of that kingdom is Nature, and the queen in the kingdom of Nature, despite her venerable age, was the proud, wise beauty Physics.
From century to century, she learned to understand her household, the ability to manage and dispose of it. But the man did not immediately recognize the power of the queen. There was a time when man was possessed by fear of Nature.
Lightning blazed, thunder rumbled, frost bound the earth, storms and storms raged, and people did not know why all this was happening, and often died.
And this greatly upset the queen. It was then that she began to gather her army from the most inquisitive, most patient people and showed them that they need to notice the repetition of phenomena, their interconnection, not be afraid of wind and lightning, but try to use them to their advantage.
The army of the queen was constantly growing, and her sergeants and commanders began to appear in it, and among them were giant scientists, whose shoulders served as a reliable support in replenishing the pantry of knowledge in the queen's palace.
Here they are - the great creators of history: Archimedes, Aristotle, Galileo Galilei, Isaac Newton, Lev Davydovich Landau, James Maxwell, Michael Faraday, Konstantin Eduardovich Tsiolkovsky and many others, and, of course, the legendary scientist Albert Einstein.
2 host:
He, like no one else, looks like a fairy-tale wizard who overturned many of the usual ideas about the world for a person.
Einstein, not without the help of the queen, noticed that there are laws of nature that are valid only within certain boundaries of the kingdom.
So, with a ruler and a clock moving in an ordinary plane, nothing will happen from the point of view of an aircraft controller left on the ground, but if he looks at them in a rocket that rushes at a speed close to the speed of light, then the airport attendant will immediately notice that the ruler became shorter, and the clock went slower.
Biography of Einstein (Annex 2)
After the biography, very short classical music sounds, at this time the students organize a skit.
1 presenter
Guys, we ended up in Syracuse, to King Hieron, who lived 250 years before our era.
King Hieron. (sitting at the throne)
Servants, call here Archimedes!
Many years to you, my lord!
Tsar (removes crown from head)
I want to check the honesty of the master who made the golden crown. Find out without breaking it, is there an impurity in it? (leaves)
The servants take away the throne.
Archimedes takes out a scale with weights, measures the mass of the crown. In the hands of the pen sits and says aloud:
First I found that the density of pure gold is 19.3 times that of water. So, if you find the density of the crown, then the order of the king will be executed.
It was easy to weigh the crown, but how to find its volume? After all, the shape of the crown is wrong.
1 presenter
For many days Archimedes agonized over the answer.
Archimedes with a towel in his hands goes to the bath, "plunges" into it and shouts: Eureka! Eureka! I found!!
Archimedes (approaches the king)
I completed your task - I weighed the crown first in the air and then in the water (demonstrates). From the difference in weight, I found a buoyant force equal to the weight of water in the volume of the crown. Knowing the volume of the crown, I determined its density, and it turned out to be less than the density of pure gold.
So the master is a thief and a swindler? Punish him!
And I ask you, Archimedes, what other discoveries have you made in science?
I discovered the rule of the lever, invented the propeller, and burned the enemy fleet with the help of a concave mirror.
You, Archimedes, the great scientist, your name all young physicists will know!

Isaac Newton? Did you discover the law of gravity?
Newton Yeah.
Newton sits under a tree in the garden, drinking tea. Apples and leaves fall from the tree. He argues: "Why do apples and leaves always fall down? Why not to the side? But towards the center of the Earth? So there must be a force like gravity that extends throughout the universe? What is the similarity between honey, an apple and the moon?"
He takes a pen and writes. He approaches the telescope and looks into it.

The history of the incandescent light bulb is a chain of discoveries made by different people at different times.
And Edison here made a significant contribution, and Lodygin, and Yablochkov, who is rightly considered one of its pioneers.
And, besides, we must definitely remember the outstanding Russian physicist Vasily Petrov, who, back in 1802, observed the phenomenon of an electric arc - a bright discharge that occurs between carbon rods-electrodes brought together at a certain distance.
One should also remember the names of Vladimir Nikolaevich Chikolev and Alexander Ilyich Shpakovsky, who also contributed to this outstanding invention ...

1. Explanatory note
It is no secret that in recent years, interest in the study of subjects of the natural and mathematical cycle has been declining. We must not forget that the future of our students and the country depends on the development of science and technology. This imposes on teachers of physics certain responsibilities for the preparation of primary knowledge, on which the formation of successful specialists in various fields will be carried out.
One way to increase student interest is through extracurricular activities such as subject weeks. The main task of holding a week of physics is to develop students' interest in the subject, as well as to update the knowledge of schoolchildren. Uniqueness subject week is that students from all grades of the school take part in its implementation.
The weekly plan is as follows: every day there is one event. They are prepared for each age group separately (grades 7-11) and take place in the form of various competitions, games and excursions. The characteristics of schoolchildren are taken into account; the level of their knowledge, skills and abilities; their career orientation.
We, as young professionals working at school for only the first year, do not have such a generalized work experience, but the ardent desire for self-improvement, self-education and self-development as teachers help us in our work.
2. Methodical development "Week of physics at school"
Goals:
1. Activation of cognitive and research activity of students through game forms of extracurricular work, development of students' creative abilities

Extracurricular activity in 7th grade
"Evening of entertaining physics"
Purpose of the event: to promote the development of cognitive interest in the study of physics among schoolchildren at initial stage studying the subject.
Event objectives:
- To promote students' awareness of the importance of studying the physical phenomena around us.
- To consolidate and generalize students' knowledge on the topic "Atmospheric pressure".
- Develop spatial, logical thinking, the ability to draw conclusions.
- Develop the ability to clearly express your thoughts.
- To form the ability to work in a team, in a group.
- To educate the aesthetic perception of the world on the example of physical phenomena.
Preparatory stage.
At this stage, a group of 7th grade students assisted the trainees in designing a wall newspaper dedicated to the evening of entertaining physics. The newspaper presented interesting materials from the life of physicists, riddles, quotes from great scientists, and a crossword puzzle. The guys brightly and colorfully designed the newspaper, and hung it up for everyone to see a week before the event.
Event progress.
Physics! What a capacity of words!
Physics is not just sound for us!
Physics - support and foundation
All sciences without exception.
Hello guys! We invite you to take part in our fun physics evening. 3 teams of 7th grades will fight for the victory today. And in order for justice to prevail, we decided to create a judicial commission. To take the place of honor of the jury, please:
- Churkina Nastya, 10th grade student.
- Valuyskaya Daria, 11th grade student.
- Levina Valentina, 5th year student of the Faculty of Engineering and Physics of the National Research University "BelSU".
And we have the following request to the jury: be fair, objective. Announce the results after each round.
So here we go!
1 competition. Greetings.
Teams choose captains, come up with a team name, a motto and a wish for rivals. All of this has to do with physics. After that, the facilitators divide the board into three parts. The team names are there. The scores will then be recorded in these three columns. Maximum for the 1st competition - 3 points.
2 competition. Physics quiz.
And now we will test your knowledge of physics. Each team will have to answer 3 quiz questions. If the team does not know the answer, then the opposing team answers. For each correct answer, 1 point is awarded.
- Who first measured atmospheric pressure? (Torricelli)
- Name a device for measuring atmospheric pressure. (mercury barometer)
- Name a device for orienting on the earth's surface and determining the cardinal points. (Compass)
- Why do trees crackle in the forest during a severe frost? (When freezing, the water expands, the bark breaks with a bang)
- Why is warm bread heavier than cold bread? (There is a lot of moisture in the hot, it has evaporated in the cold)
- Why does water extinguish fire? (Cools a hot body, absorbs a lot of heat, the resulting steam does not let oxygen pass to the burning body)
- What is heavier - a pound of iron, or a pound of fluff? (their weight is the same)
- In which room does the smell of perfume spread faster - warm or cold? (Diffusion is faster in a warm room)
- What force causes the ebb and flow in the seas and oceans of the Earth?
(Gravity from the side of the moon)
While our esteemed jury is scoring, we'll show you a little trick. Try to explain it in terms of physics.
"Flying Tea Bags" We open the tea bags, cut off the thread with the label, pour out the tea leaves. We put the bags on the table and set fire to it. Warm air carries the burning bags up with it.
3 competition. "Explain Experience"
For each team, 1 experience is demonstrated. The team must give an explanation for what they see. The maximum for the competition is 5 points.
- "Heavy Newspaper". A long wooden ruler is placed on the table and struck with the hand. The line falls. Then the ruler is covered with a newspaper and hit again with force. The newspaper is torn, and the ruler remains in place. Since the area of the newspaper is large, the air pressure on its surface is large enough so that the ruler does not fall.
- "Two fluids are swapped." Wine is poured into one glass, water into another. We cover the glass of water with a plastic card and turn it over a glass of wine. Between the glasses we make a small gap. We observe how the wine rises in a thin stream into the upper glass, and the water flows down. This happens because the density of water is greater than the density of wine. Therefore, a lighter liquid tends to rise, and a heavier liquid tends to fall.
- "We flatten the bank." Boil some water in aluminum can from soda. We take the jar with tongs and turn it over into a container with cold water. The bank is flattened. The fact is that in an unheated jar there is water and air. When the water boils, the air in the jar is replaced by steam. Then the cold water cools the steam, and it turns into a few droplets of water. There is no more air in the jar, therefore, the pressure in it is below atmospheric. Under its action, the bank is flattened.
4 competition. "Pantomime"
And now it's time to loosen up a bit. Each team must go to the center of the class and show, with the help of pantomime, the aggregate state of the substance that is written on their card. (Cards with the name of the state of aggregation received before the competition.)
- liquid
- solid
- gaseous
The maximum for the competition is 3 points.
5 competition. Captains Competition.
- Place a strip of paper on the table edge-on. (Fold in half, twist, etc.)
- Guess what's in the black box.
Of this substance, Leonardo da Vinci said: “It can be healing, poisonous, sulfuric, salty, scarlet, gloomy, furious, angry, red, yellow, green, fat, skinny. It all depends on where it is.” (The correct answer is water)
- Pour exactly half of the water from a cylindrical glass in one go. (Gently pour water until the edge of the bottom appears)
The captain who is the first to complete each task brings his team 1 point.
6 competition. "Puzzles"
- A beautiful yoke hung over the forest. (Rainbow)
- What can't you pick up from the ground? (Shadow)
- No one saw him, but to hear - everyone heard. Without a body - but it lives, without a language - it screams. (Echo)
- First - a shine, after a shine - a crack, after a crack - a dance. What's this? (Lightning, thunder, rain)
- It does not burn in fire, it does not sink in water. (Ice)
- He will tell everyone, albeit without a language, when it will be clear when - clouds. (Barometer)
- Two sisters rocked, they sought the truth. And when they did, they stopped. (Scales)
- A miracle bird, a scarlet tail, flew into a flock of stars. (Rocket)
- Sleeps during the day and looks at night. (Moon)
- I'm sitting under my arm, and I'll point out what to do. Either I will let you walk, or I will put you to bed. (Thermometer)
- In the evening, in a glass cap, the sun sits on a thread. (Bulb)
- It warms in winter, smolders in spring, dies in summer, comes to life in autumn. (Snow)
Give each team 4 riddles. Each correct answer is 1 point.
7 competition. "Explain Experience"
Demonstrate 1 experience for each team. Team members must explain it. The maximum for the competition is 5 points.
- "Four floors of liquids". Liquids of different densities, tinted in bright colors, are poured in layers into a tall glass. Schoolchildren see that the liquids do not mix. Explanation - see the experiment "Two liquids change places."
- "Egg in a Bottle" Throw the burning paper into a bottle with a wide neck. The air in the bottle becomes rarefied, and the egg is sucked into the bottle under the action of atmospheric pressure.
- "Get the egg out of the bottle." We throw ignited paper into a three-liter jar, sculpt plasticine on the neck for tightness. We lower the bottle with the egg neck down. The egg is served in a jar. As the air in the can became rarefied, the pressure inside the bottle was higher than in the can.
8 competition. Math quiz.
Mathematics is the queen of all sciences, but the servant of physics. Physicists without knowledge of mathematics - nowhere. Please answer the questions of our comic quiz.
- Birch grew. She had 28 branches. Each branch grew 5 apples. How many apples were on the tree? (Apples do not grow on a birch)
- The room has 4 corners. There is 1 cat in each corner. And opposite each cat sit 3 more cats. How many cats are in the room? (4 cats)
- Once, sitting in a trolley bus, I decided to do a little calculation. I counted all the passengers in the trolley bus. There were 17 of them. The trolleybus started, then at the stop 2 people got off and 6 people got on. Be careful. At the next stop, 10 people got on and no one got off. At the next stop, 12 entered and 7 left. At the next, 4 people entered and 8 left. And then, at the next stop, the gentleman entered alone with a whole bunch of new clothes. How many stops were there? (5 stops)
The team whose captain first raised his hand answers. For each correct answer - 1 point.
Our fun evening is coming to an end. In the meantime, the jury is summing up the results of all competitions, we want to show you one magical liquid.
We are preparing a non-Newtonian fluid, we invite the children to play with it, we talk about its properties.
Reflection. Summarizing.

Music No. 1
Part No. 1 (Greeting. Explanation of the goals and objectives of the event)
The professor comes out (talking on the phone):
V: Hello! Hello! Professor Know-It-All is on the phone! Who is speaking? Research Center!?… So, hush! I have important conversation! What kind of nonsense are you talking about... we don't have smart kids?! How dare you!… This is complete nonsense!… (Confused) Research? What research?! No, no, I'll prove it to you! Right today, right now, being in this room! I will find you talented, smart and quick-witted children!!! The conversation is over! (Hangs up the phone)
P: - (Confused) No, well, you need to come up with something like that ... So, so, what to do ... I think my assistant, Dormidont Menzurkin, will help me. (claps his hands 2 times)
(M appears)
M: - Professor, you called me?
P: - Yes, can you imagine, they called from the Academy of Sciences, they claim that all children do not want to know anything, they only know that 2 by 2 =
Denis (not sure) 4 ?
5 by 5=
Denis (More confident) 25
7 by 7=
Denis proudly 47
Prof: What's wrong with you, buddy? Forgotten? Guys, how much will the 7th 7 be? Guys how much?
M: - Professor, I didn’t sleep well (guilty) ... However, professor, where will we look for smart, and even quick-witted children?
P: - Look here, carefully (points to the hall)
M: - Wow, so ... I know how to test their intelligence. (Professor Runs away behind the screen) At all times, the guys were scientists, but there were charlatans, and now we will see for ourselves. Meet the great magician Leopold Mukhlyuev.
Part No. 2 (Joke improvisation of tricks) I turn on the music
Mysterious music sounds, the Professor appears (in the form of a magician) and begins to show funny tricks:
Scotch with a spoon (2 spoons, scotch)
Bitten finger with sausage (sausage)
Handkerchief in hand (handkerchief)
Disks (disks)
Assistant takes off (cape)
Maid.mp4(example)
Part No. 3 (LECTURE)
Professor: No, no, no! You guys didn’t think that these were real tricks, did you? tell you a secret? This is done very easily.
Did you notice how quickly my assistant ran away? Although, everything is relative ... If we compare the speed of a Human’s running, for example, with the speed of a crawling SNAIL, then of course a person is downright very fast, because the Snail crawls at a speed of 1.5 mm per second or 5.5 meters per hour, and this is 1000 times slower than a human. Compared to a snail, a MAN is, of course, fast ... But what if we compare a Human, for example, with a HARE, or a HORSE? BUT? (Laughs loudly) And we can only overtake an eagle in an airplane. Yes, everything is relative (scratches the back of his head) ...
Q: My friends! And what do you think, what movement can a person do the fastest?
Children: - Run, jump ..
Q: - Run away to the canteen?
M appears: - And I can do it quickly (shows movement and runs behind the screen)
P: - (The professor takes a bag with a round head and with words from the table):
The fastest movement ... (goes behind the partition, puts M.'s head on the partition, opens it, shows it as on the layout), which a MAN is capable of is WINNING with his eyes. (M. demonstrates). No wonder people say - "in the blink of an eye", or "moment" - from the word blink. The blinking is so fast that we don't even notice a temporary eclipse of the field of view. (Closes the bag. Removes from the partition. Throws it offstage.)
Some smart people have claimed that they are so fast that they can catch a bullet with their teeth! In one old, old circus, I saw one number.
Music circus number 3 Denis
2. Catch a live bullet with your hands (trick with a clown bullet)
Ladies and gentlemen, only today, only now, your attention will be presented with a deadly number. Fearless Giuseppe Garibaldi, who will catch a bullet with his teeth! During this number, 15 artists died, three were injured, and one still wakes up at night and shouts: Mom, Mom, I want to pee. The shot is very loud, so if there are panties in the hall, let them close their ears. So here we go, meet the world famous, fearless Giuseppe Garibaldi. Giuseppe appears. (Growls, sees the gun a little scared) The bullet will fly out of the gun, tear the newspaper and end up in Giuseppe's teeth. The shot is made from 5 steps!
Applause. And now, ladies and gentlemen, let's complicate the number, the shot will be fired from 3 steps. Giuseppe are you ready? (J. shakes his head, like no, the tooth hurts) He is shown a fist
false shot
Here is the Charlatan! (runs around from the other side) Rogue! (runs around from the other side) I'll shoot you. Eh, ran out of ammo. I challenge you to a duel coward. (in response to "I'm not a coward, but I'm afraid ... Figushki)
Of course, this was a joke, it’s impossible to catch a bullet with your teeth, it’s even stupid and dangerous! But do you think it is possible to catch a bullet with your hands? ask guys?
During the imperialist war, a completely unusual incident happened to a French pilot. (Pantomime to French music)
Flying at an altitude of two kilometers, the pilot noticed that some small object was moving near his face. Thinking it was an insect, the pilot deftly grabbed it with his hand.
M: -Imagine the astonishment of the pilot when it turned out that he had caught not an insect ... but a German live bullet!
P: - Meanwhile, there is nothing impossible in the report about this pilot. At the end of its path, the bullet begins to move very slowly - only 40 meters per second. It was at this speed that planes flew in those days. That is a bullet
(M: - I, I!! Depicts a bullet)
and the pilot's plane (Depicts P) moved at the same speed and it is quite obvious that the pilot was able to catch her with his hand.
M: - Only with a glove, because a bullet moving in the air gets very hot.
They bow. 3 times, on the third assistant puts a bullet prof. For the collar. That one runs away
So that the guys, with certain opportunities, can grab the bullet with their hands!
Part #4
The Professor Behind the Screen Turns on Music No. 4
P: (Comes out with a device on his head "For reading thoughts")
M: - Professor, what is this device on your head and are you playing cards? Can balls red or black
P: No. And this is a device of my invention. With it, I can guess whether the card is red or black, even if I can't see it.
M: How is the professor?
P: I'll show you. I just need an assistant. Takes the child out of the room. Preferably from the first row.
: - Professor, I also want to see (takes the place of a child)
P: (In the meantime, he gives the child a deck of cards and tells him to show the hall one at a time)
- Attention ... now Seryozha will show you one card at a time, and without seeing them, I will guess what suit they are (red or black).
Focus with guessing the suit.
need music number 4 (will include professor, music with silence in front)
We repeat with the person who wishes, whom we "hypnotize" can be blindfolded.
The assistant goes behind the screen, pulls the stocking over his head, dressing up as an Indian and turns on the music!!
Takes out a chair, sits down (professor):
Guys, do you like to travel? I really love. I've been to a lot of places, seen a bunch of different tricks. Or reveals the secrets of the trick with the disappearance of a cigarette and driving coins into a bottle or different Interesting Facts:
When the Europeans first saw the giraffe, they called it the "camelopard", thinking it was a mixture of a camel and a leopard.
Snakes can sleep 3 years in a row without eating anything.
In their youth, the Black Sea perches are mostly girls, but by the age of 5 they radically change their sex, turn into boys!
When a giraffe gives birth, her cub falls from a height of one and a half meters.
The animal that can go without drinking the longest is the rat.
Hummingbirds cannot walk.
Europeans, having arrived in Australia, asked the natives: “What are these strange jumping animals here?” The natives answered: “Kangaroo”, which meant: “We don’t understand!”
Giraffes have a completely black tongue, the length of which can reach up to 45 cm.
A whale's heart only beats 9 times per minute.
Get up!
If I tell you: “Now you will sit on a chair so (and sit down) that you will not be able to get up, although you will not be tied”, you will, of course, take this as a joke.
So here are my friends, as then I traveled through South America and was taken prisoner by the Indians. And you know how the Indians scream, let's try. And they try. An Indian appears at the cry, running after the professor. She puts him on a chair.
Professor: And so the Indian put me not on a chair, but on a rock, you can’t move your legs under you, but put a sharp spear to your chest and ..
Native American: Abra cadabra mop
Professor: ... And he ordered me to stand up, but I couldn’t ...
The Indian removes the spear.
Professor: It turns out that in order to stand up you need to either tilt your torso forward, or move your legs under you. Nothing else. Try it. He goes down to the hall and tries with the guys. What fails? No amount of muscle effort will be able to get you out of the chair until you move your legs under the seat or lean forward with your body. This science is called balance. When you study physics you will understand why this happens.
He chooses the best, takes him to the stage with him (one of them is a girl), at this time the Indian starts music No. 6
He turns around and sees that the Indian does not let the girl go. "What's the matter?"
The Indian said something.
Professor: he says that he liked you, you are a princess and he wants to marry you, what is your name? you will hunt crocodiles with him, fry turtle eggs, drink coconut juice, and serve him in everything. must refuse ... "Guys (to those on stage) will you help free the princess?"
But for this you will need to pass dangerous tests. Aren't you guys afraid?
So we have 5 eggs. (distributing) I know that three of them are boiled, and 2 are raw! How do I know which of them are boiled and which are raw?
Just break them (and breaks your egg)
Papuan: making negative gestures.
Professor: No! We want to find the bravest today, so the egg needs to be broken on ... (the Indian points to his forehead) .... forehead!
Professor: But we will not be afraid of this test. So who is the bravest?
(Papuan: performs a drum roll, you can involve test participants in this)
At the end it turns out that all the eggs are boiled.
Joyful Papuan plays with eggs
Professor: He, I got it wrong. Everything appears to be cooked.
Guys eat more easy way. A knowledge of mechanics will help us to successfully get out of this little difficulty.
The fact is that boiled and raw eggs rotate differently. (the egg is placed on a flat plate and rotated) The boiled egg rotates very well. And the raw one is difficult to even get to rotate.
Egg twisting.
Professor: Oh, he got it wrong. But how much food does he have now! Now he doesn't need a wife. Guys go to your seats. Following the girl, “UUUU” looks sadly and goes behind the screen, turns on music No. 7
Heavenly thunder sounds, music number 7, a voice from heaven: - Oyekhalo-manaholo! The Indian falls, shaking.
Professor:- : Oh guys, the supreme god Chupacabra is angry with us. He wants gifts. Oh great Chupacabra, now we will give you something. Turns to the guys. Who has a cell phone? Let's give it to the Chupacabra.
Wait, you have food. Bring him your food as a gift. What is required for this?
Papuan: The great Chupacabra has sacred vessels that need to be filled. (takes out the bottles) Papuan: But how can I put my food in these vessels, the egg does not climb! AAA (hysterical)
Professor: Knowledge of the laws of physics will help us. The bottle needs to be broken!
At first glance, it (the bottle) seemed to everyone an ordinary half-liter bottle with a wide neck. Peeled professor hard boiled egg, put it upright on the neck - it did not fail.
- Eat, bottle, egg! - began to beg - show character.
But she showed herself not “gluttonous”, but “capricious”. Didn't respond to the call.
"Then we'll piss her off!" - the professor got down to business: he folded a sheet of paper like an accordion, set it on fire and stuffed it inside the bottle. Waited a few seconds.
- Angry! and placed an egg on top.
The paper went out, the air inside, having cooled, shrunk, and the invisible man, with a familiar “bang”, pushed the egg into the bottle.
Make an experiment on a balloon and a jar
After all, the egg is inside. Joyful Indian goes behind the screen
Music number 8
Copperfield
Professor: - My friends, would you like to fly into space? And now we will fly around all our planets, and in the end I will count your thoughts and find out exactly which planet you are on. So Guess any number from 5 to 15. For example, you guessed the number 6. Let's try. We need to start counting from the cosmodrome and only to the left side 1,2,3,4,5,6 We ended up on the red planet. Or you guessed the number 10, we ended up on the planet Zelenyavka ... The choice is great. Everyone understands how to count and in which direction? Remember what number you thought of at the very beginning. So. 1,2,3,4, and then the number you guessed. Everyone flew to their own planet? Now you need to go back, the same number of moves and the same number that you made at the beginning. Just back. I'm cleaning up the spaceport and the moon. Ready? And I will count 1,2,3,4, and so on. When you're done, remember which planet you're on. Happened? I know that you are not on the planet "O", not on "Venus" and on "Mars", you are not on the planet "Zelenyavka" either. Now count 4 moves in either direction. You are not on the pink planet, etc. I know you all flew to the planet (pause) "Knowledge"
Friends, my knowledge helps us all and in everything. Today you learned a lot of interesting things and we realized that you are exactly the children we were looking for: Brave, smart, talented and quick-witted. Strive for knowledge like a flower for the sun. Learn lessons and listen to mom and dad. Grow big and strong. These are the people our great country needs. Until we meet again guys. Today Andrei and Denis tried for you, from the Ordinary Miracle Theater. Bye!
