Week of physics in a comprehensive school material on physics on the topic. Scenario of the physical evening "Physics is interesting!" An evening of entertaining experiments in physics script
Physical evening "Physics is interesting!"
Purpose: formation cognitive activity students.
1. Poem by I. Kuznetsov “What is physics”
What is physics?
Probably interesting...
I'm still studying in the sixth,
I don't know much.
Everything in physics moves
It's clear to anyone
It oscillates, it rotates.
And it can be dangerous.
But if you know the laws
And traffic rules
You can do experiments
Without any doubts.
There is a law of inertia,
He rules the roads.
Come to the traffic light
Go to the green light!
If there is no traffic light
The green light is not on.
"Look at the crossing" -
Physics gives advice.
The car is moving fast
Brakes, erasing tires,
Brake continuing the way.
Don't forget about it!
If rain or ice,
Look back, look ahead.
There is inertia, like here-
Brake will add path.
Often puts life in a dead end.
You think for a moment
What about all your secrets
In physics you will find the answers.
If you enter the water
You will become lighter, you will swim.
Why lay your ears
What if you dive deeper?
High above your head
atmosphere above you.
So it's two tons
Everyone wears?
Rifle shot in the dash
It also requires skill.
And press the butt harder
And you won't hurt your shoulder.
Physics knows it all
And scientifically explains:
How to escape lightning
So that the x-ray was not dangerous,
And what in the heat and cold
The meaning of clothes is to change color,
Drop the spoon into the glass
before pouring tea.
A thousand different questions
You can ask physics.
Make the right decision
If you know a lot
You need to follow the advice
If you are friendly with physics,
You can extend your life.
2. Poem "Physics"
I'm not tired of being surprised
Miracles that are on Earth,
Fan on the table.
Planes fly through the clouds
Ships are sailing on the sea.
How about these mighty things
Could people dream?
I entrust myself to the tram
I look at the movie screen.
Understanding this technique
I'm still amazed by her.
Current flows through the wire
A satellite walks the sky
A man should be amazed
Human miracles!

(Morse code.)
15. Answer the questions:
1. Which is heavier: a ton of iron or a ton of fluff?
2) Why can a person run on thin ice and can't stand on it without falling through?
(The result of the action of a force depends not only on its magnitude, but also on the time of action. When a person runs, the interaction time is short and the ice does not have time to break through.)
3) Is it possible to throw a body so that it does not fall to the ground?
16. Explain the experiments (the teacher demonstrates)
1 .Water boils at the top of the tube.
How to get a nut out of a saucer of water without getting your hands wet?

17. Interesting facts.
1c) During the day, a person spends about 5 hours on his feet (walks around the room, street). At the same time, we take an average of 30,000 steps, which is about 20 km., And during the year 7200 km.
2c) Crocodiles swallow stones, the total mass of which is one hundredth of its mass. The stones serve as ballast, allowing crocodiles to walk along the bottom of the river and quickly drag their prey under water.
1c) The maximum temperature that a person can withstand,
160 degrees. a temperature of -104 degrees a person can tolerate 26 minutes, -93 degrees - 33 minutes, and -71 degrees - 1 hour.
2c) Any fish in water is weightless, since the density of the body of a living fish is equal to the density of water.
18. 3 people are invited to the stage. ( Romanenko)
BUS RIDE
There are three people on stage. Everyone receives an inflated children's balloon and holds it by a string in his left hand raised up. Participants must introduce themselves as bus passengers. This ball should show how the position of the passenger’s body relative to the seat changes when he moves: the bus drives away from the station, brakes sharply, makes a left turn at high speed, moves evenly and straightly, brakes smoothly, makes a right turn, brakes sharply.
19. Quiz ( Kuznetsov)
1) A fox, running away from a dog chasing it, is often saved by suddenly making sharp movements to the side just at those moments when the dog is ready to grab it with its teeth (why is it difficult for a dog to catch a fox?)
2) When weeding, should weeds not be pulled out of the ground too sharply, even if they are weakly retained in the soil?
3) Why is the circus rider bouncing
up on a galloping horse, hits
back in the saddle?
4) Why in an airplane during takeoff and landing
Do flight attendants hand out lollipops to passengers?
5) Why don't bats run into obstacles even in complete darkness?
6) Why bat often sits on people's heads?
7) Why is it impossible to cook meat high in the mountains?
8) Why are we bigger in a river with a muddy bottom?
do we get stuck in a shallow place than in a deep one?
1) The dog runs past by inertia.
2) With a sharp pulling out, the roots, by inertia, remain at rest and do not have time to move, so the stems break off.
3) The rider, bouncing up, maintains his original speed.
4) A sharp change in pressure stuffs the ears and even causes pain. When swallowing, the middle ear is connected to the oral cavity and the pressure in it becomes equal to atmospheric pressure.
5) Bats navigate in space using ultrasound.
6) The hair absorbs the ultrasound emitted by the mouse, so it does not feel the obstacle.
7) Due to the height of the mountain, the column of air above it decreases, so the atmospheric pressure decreases there. At reduced atmospheric pressure, the boiling point of water becomes lower and water boils at a temperature below 100 degrees. The temperature of the water does not change until it is all boiled away. And the meat is cooked at a temperature of at least 100 degrees.
8) A buoyant force acts in water, which depends on the volume of the immersed part of the body.
20. Explain the experiments (Romanenko)
1. A ball worn with a newspaper is held on the ceiling.
2. Smoke in a glass. (Disappears if the wire is connected to an electrophore machine.)
3. A man with a sultan.
4. Dancing clowns.
21. Physicists are joking again
1. Somehow a physicist and a mathematician meet. Physicist asks:
Listen to why the train wheels are round, and when it goes they knock.
It's elementary. The area of a circle is a PI ER square, so this square just knocks.
2.News from the world of nuclear physics: The stomach of a kitten is no larger than a thimble, therefore, those two liters of milk that he is able to drink in an hour are in his stomach under a pressure of 50,000 atmospheres, which is ten times greater than the pressure at the epicenter nuclear explosion.
3. Scientists of the physical laboratory of N-sky state university empirically proved that almost any hair dryer can create a powerful air resistance that can greatly slow down the movement of large objects.
The experiments were carried out on busy highways, the hair dryer was directed by the hands of the technician towards moving cars, which, under this influence, reduced the speed, despite their aerodynamic properties, and could pick it up only after passing the technician with the hair dryer.
At the same time, scientists from the Department of Linguistics of the same university collected a huge amount of folklore expressions based on the statements of drivers passing by a technician with a hairdryer.
4. When asked why the heating was given 10 days late, the Minister of Energy said: " It's a shame not to know physics! When heated, water expands and does not fit well into pipes."
22. Scene "Exam in physics"
23. Real fact.
Einstein - to Charlie Chaplin: "Your film" Gold Rush "is understood all over the world. You, undoubtedly, great person and you will be recognized by the people!"
Charlie Chaplin - Einstein: "I admire you even more. Nobody understands your theory of relativity, but you still became a really great person!"
6. One day Newton's guests complained that the gate to his garden was hard to open, and asked to make another, better one. “I don't know which is better,” replied the physicist. - And so everyone who enters pours at least a liter of water into the tank for the house.
24. Do and explain the experiments.
1. Blow on the box so that it moves towards you.
2. Read the words correctly. (Words are read through a glass of water)
3. Holes are made in the bottle. Why is water not pouring out through these holes? What needs to be done to get the water out?
4. What happens if you blow between two balloons?
25. Song "Wizard-half-educated"
26. Conclusion. Teacher. With this song we end our evening. This song is a warning not to become half-educated.

Equipment: two candles, matches, glass jar. Candles are lit, one of them is covered with a jar and goes out after a while. Question: Why did the covered candle go out?
There is a postcard on the glass, and on it is a coin. With a click of the hand, the card is knocked out, and the coin falls into the glass. Why?
8th grade
Take balloon, put it on the neck of the bottle and push it inside. Try to inflate a balloon - you fail
Boiled egg "creeps" into the bottle. We take a half-liter bottle (milk), a boiled egg, peeled, a piece of paper and a match. We make sure that the egg placed on the neck of the bottle does not fall inside, but slightly enters it. Burning paper is lowered into the bottle and the egg is placed on the neck again. After a while, it falls into the bottle. Why?
Grade 9
Equipment: ebonite stick, a piece of woolen cloth, a piece of cotton wool. After rubbing an ebonite stick on a woolen cloth and contacting it with a fluff (fleece), the latter begins to repel from the stick and hangs in the air.
"Diving Egg". For the experiment prepare a weak solution of hydrochloric acid into which a raw egg is dipped. At the same time, the following is observed: the egg first sinks, then floats up, rising to the top, sinks again, etc. The egg spontaneously dives into the water. Why?
Quiz
If we look at a drop of highly diluted milk through a microscope, we can see that small drops of oil floating in the liquid are continuously moving. Explain this phenomenon.
Answer. Brownian motion.
Why can't burning kerosene be extinguished with water?
Answer. Water is heavier than kerosene and it will sink down and not close the air to the kerosene.
.Which is warmer: in three shirts or in a triple-thick shirt?
Answer. Three shirts.
16. Which egg - boiled or raw - will rotate longer? Why?

Among all the mass extracurricular activities, evenings are the most popular among schoolchildren. However, the preparation of evenings presents great difficulties. First, this is a physical evening and its the main objective- to encourage students to a deeper and more comprehensive study of the subject, to instill in them an interest and taste for physics. Secondly, it is necessary to carefully consider not only the content, but also the form of the evening. It should be lively and exciting, but at the same time, entertainment should not obscure the main thing - the cognitive value of the evening. The task of the organizers of the evening is not just to entertain students, but to activate them as much as possible. For those students who do not yet have a serious interest in physics, are still passive in relation to it, the means of entertainment can serve as the first step towards becoming interested in the subject. The next step should be to cultivate a deeper and more serious attitude towards knowledge. In relation to another group of students who are already interested in the subject, the elements of entertainment will serve as an additional means of revitalizing educational material and diversity of the process of its perception.
About the party entertaining physics school students should be informed by a colorful and interesting announcement in content, for example, drawn up in the form of a rebus or in poetic form.
Evenings of physics and technology is one of the most exciting, useful mass extra-curricular activities in physics. A well-spent evening often leaves a lasting impression on students, and for some of them marks the beginning of a serious passion for physics or technology.
Evenings of entertaining physics are especially popular with students in grades VII-VIII. This is understandable: at the age of 13-14, schoolchildren are attracted to everything unusual, striking the imagination. However, the teacher should not strive to make the evening "as entertaining as possible." The main principle of material selection is the content of the evening, otherwise it may turn into a heap of spectacular spectacles and lose its cognitive significance. Necessary condition The success of the evening of entertaining physics is the variety of forms of work with students used on it. In addition to traditional entertaining experiences, attractions, quizzes, students are also interested in other forms of work: short entertaining physical riddle stories; stories containing physical errors (students must detect them); small entertaining plays; riddle pictures with questions to them.
Of particular methodological value are such forms of work that allow students present in the hall to be not only spectators, but also active participants in the evening. In this regard, the form of work carried out under the name "Make Improvement!" is very valuable. In it, schoolchildren are shown a model, drawing or diagram of a device, machine, instrument or structure. They give a description of it and note that this design contains one or another imperfection. Explain what it is. Everyone is encouraged to improve this device. Sometimes a model or diagram of a device can be assembled on a demonstration table. In this case, students are asked to demonstrate the improvement they have made.
A significant place at the evenings of entertaining physics is given to entertaining experiments. When choosing them, preference should be given to experiments in which phenomena are shown that are widely used in technology, everyday life, or are often observed in nature. The value of a demonstration is increased if it is followed by short story about the practical use of the phenomenon shown. Let's give an example of an evening of entertaining physics for students in the 7th grade.
The purpose of the evening is to help students understand the content of the topics: “Atmospheric pressure” and “Archimedean force” more deeply. Show that physical phenomena and laws can be discovered and demonstrated sometimes in the most unexpected way, to interest students in the possibility of independently performing fascinating physical experiments and observations physical phenomena in everyday life.
Evening plan
- 1. Opening speech of the host (introduces those present to the program of the evening).
- 2. Brief story about the importance of the atmosphere for life on Earth and about the structure of the atmosphere.
- 3. Demonstration of experiments explained by atmospheric pressure: an egg “crawling into a decanter”, “heavy newspaper”, “punished curiosity”.
- 4. The story of the outstanding ancient Greek scientist Archimedes.
- 5. Demonstration of experiments on the topic “Floating conditions for bodies”, for example: paraffin that does not float in water (the bottom of a glass vessel is covered with a thin layer of paraffin and a piece of paraffin with a flat base is placed on it, water is carefully poured into the vessel, paraffin does not float); lifting a homemade balloon filled with hot air; how to behave when drowning (a wooden doll floating in water sinks deeper when its hands are raised).
- 6. Showing riddle pictures. For example, the figure shows a section of the sea thickness. A sunken ship "hangs" in the water, which did not reach the bottom. Question on the picture: "Could it be so?"
- 7. Presentation of prizes to active participants of the evening.
Physical and technical evenings are devoted to topical and interesting issues modern technology, history of technology, development prospects individual industries physics and technology. At the evening, 3-4 students make short presentations. Reports should be well illustrated. In addition to visual aids, they demonstrate operating models of technical installations, home-made devices, fragments from films. Such evenings are prepared by students - members of a physical or physical-technical circle. These evenings can be a kind of creative report of the circle members about their work. Part of the evening can be devoted entirely to the results of the work of the circle.
Preparation of physical evenings. Conducting any evening in physics requires careful and lengthy preparation. It should be started 1.5-2 months before the evening. At the first organizational meeting of participants in the preparation and holding of the evening, the teacher reports an approximate plan for the evening. After discussing the plan, tasks are distributed among the participants. The participants of the evening are divided into several groups: speakers; responsible for the preparation of experiments; responsible for preparing the announcement and issuing a special issue of the newspaper, bulletin; equipping the stage and hall, etc. For each group, a deadline is set for the completion of all preparatory work, as well as deadlines for the completion of individual tasks.
After completion of all the preparatory work, a few days before the evening, a general rehearsal is held with a discussion of each part of the evening. It should be held in the same room where the evening will take place. Here it is important to pay attention to the fact that all work on the stage is carried out clearly and smoothly, so that there are no long breaks when moving from one form of work to another, so that all participants in the evening know when to perform, and act confidently and completely independently.
A few days before the evening, a colorfully designed announcement with his program is posted. A well-designed announcement captures the attention of students and makes them want to participate in the evening.
Great importance have a choice of theme and the name of the evening. The theme of the evening should be related to curriculum and accessible to the understanding of students, be interesting and exciting for children of this age. The teacher's job is to tactfully suggest a topic and captivate students with it.
The theme of the evening (or conference) can be:
- § memorable dates and significant events in science and technology ("Radio Day", "Evening, dedicated to the day astronautics”, etc.);
- § major achievements in science and technology (“Lasers are a miracle of the 20th century”, “Low temperatures in science and technology”, etc.);
- § life and work of great domestic and foreign scientists (“M.V. Lomonosov - our first university”, “Life and work of I. Newton”, etc.);
- § individual topics or sections school curriculum(“Friction”, “The law of conservation and transformation of energy”, “In the world electric charges and fields", "Electrical and magnetic fields in the service of man”, etc.);
- § questions revealing the role of physics in human life and the development of technology (“Physics around us”, “Physics and medicine”, “Physics and music”, “The role of physics in the development of transport”, “Atmospheric pressure and life on Earth”, etc.). P.).
An evening (conference), like any mass event, requires a very precise organization. The purpose of the evening is to reveal the whole topic in a strict sequence and in an interesting way. Therefore, the order of speeches should be well thought out, and the speeches themselves should be short and clear. If this is not done, then the evening may drag on and, instead of awakening interest, it will cause a backlash. Fatigue will come, and all the work of preparing it will be in vain. The evening will seem boring to the children.
If the evening is short, but very interesting, it will increase students' interest in physics and they will look forward to the next evening, there will be more willing to take part in its preparation and conduct.
The method of preparation and the form of the evening (conference) may be different depending on the topic and the goal. Evenings and conferences are most often organized in the traditional form of alternating student messages, with extensive use of demonstration experiments and technical means.
One of the forms of evenings most beloved by schoolchildren: competitions, evenings-tournaments. Such an evening, usually held in the form of a competition of two or three teams, is popular among schoolchildren because it is both a competition, a game and a fun performance. Teams are formed of 10-12 people, each of which is prepared in advance. During the evening-competition, team members compete in answering questions, setting up experiments, acting out dramatizations, etc. At the same time, it is important that each of the competitions proposed according to the scenario carries a certain cognitive load, and when evaluating the answers, the physical essence of the answer is put in the first place.
The success of the team depends on the coherence in the work of not only team members, but also its fans, who together with the team make up a single team, which allows you to involve big number students.
This form of work is successfully practiced in both junior and senior classes.
The success of the evening largely depends on the design of the room in which it takes place. After all, every evening, no matter how meaningful it may be, is still a kind of holiday, and you need to strive to make it bright and interesting, not like ordinary lesson. Bright posters, posters with the statements of scientists, newspapers, stands, a decorated stage, demonstration devices and technical equipment - all these are indispensable attributes of decorating the room where the evening takes place. It is necessary to take stock of the evening, to award the winners, to issue a newspaper or a stand covering the results of the evening.

And it is very important to know and understand the basics,
To apply this knowledge in life.
PROGRAM OF THE EVENING.
1. Physical minute.
2. What do we know about great physicists.
3. Demonstration of entertaining experiments with an explanation of the essence of the phenomena.
Teacher's word:
Hello guys! Today we met with you in order to be surprised. The fact is that physics is an amazing science. There are many physical phenomena going on in the world. All of them are explained on the basis of the laws of physics.
Fizminutka The host asks riddles and questions. Riddles are selected on the theme "Nature and phenomena in it."
What can't you hide in a chest? (a ray of light)
Question. What color is white light?
Answer. White color consists of seven primary colors - red, orange, yellow, green, blue, blue, purple. An ox roared at the table of villages, a hundred rivers away. (thunder)
Question. A storm is raging in the distance. Which phenomenon will we fix first: will we see lightning or hear thunder?
Answer. We will see lightning earlier, since the speed of light is 300,000 km/s and the speed of sound is 340 m/s at 15°C in air.
It does not sink in water and does not burn in fire? (ice)
Question. When can ice be a heater?
Answer. When another body in contact with ice has a temperature lower than that of the ice.
Without arms, without legs, but climbs into the hut? (warm, cold)
Question. Why do many animals sleep curled up in cold weather?
Answer. A coiled animal has less body surface, so it cools less due to less contact with cold air and less convection.
Don't pick me up and lift me up
do not cut with a saw,
Do not cut down and do not drive away
do not sweep with a broom.
But it's time for me to...
I myself will leave the yard. (SHADOW)
Question. How to get a shadow of different lengths from one stick?
Answer. You need to tilt it at different angles to the sun.
The edge is visible, but you will not reach it. What's this? (horizon)
Question. Can the horizon be the body of reference?
Answer. No, because when moving, it moves with the observer.
What goes without moving? (time)
Question. Does time always go at the same speed?
Answer. No, its speed depends on the speed of the frame of reference.
Leading
Scales, a dynamometer, a beaker, a ruler, a thermometer, and a watch are numbered on the table.
Now you will hear proverbs and sayings. Your task is to connect them with the instruments and devices on the table.
1. Two sisters rocked, they sought the truth, and when they achieved it, they stopped. (Answer: scales)
2. On the back of the tongue, what will he say - people believe. (Answer: dynamometer). .
3. They stand - they are silent, they go - they sing. (Answer: clock)
4. Nema and deaf, but allows you to determine the volume of liquid. (Answer: beaker)
Great physicists
The facilitator reads passages or poems dedicated to the discoverers, students should name the names.
This great man theoretically substantiated the possibility of flying into space with the help of rockets, gave the first schematic drawings of spacecraft, performed calculations
rocket movement and for the first time pointed out the need to create in orbits around the Earth
intermediate stations for flights to other bodies solar system. And also he
wrote very interesting books "Beyond the Earth" and "On the Moon".
Host Who is this great man? Answer: Konstantin Tsiolkovsky
Leading I took off first,
Well, you followed me.
I'm gifted forever
like a child of humanity to heaven by Earth.
That April the faces of the stars
frozen without caress,
mossy and rusty
Warmed by those ascending in the sky
Smolensk rusty freckles.
Host To whom did Yevgeny Yevtushenko dedicate this poem? Answer: Y. Gagarin
Leading
He was a scientist and a poet.
He thought about darkness and light.
What are the similarities between cold and heat?
What can be made from glass?
How is porcelain made?
And what is hidden in the bowels of the mountains?
He studied paint and color.
He created the university.
Risking your head
Charge measured thunderstorm.
He was strong in eloquence.
He is an astronomer. He is a geographer.
And as the poet said about him:
"He himself was - the university!"
Host About whom in question in this poem? Answer: M. Lomonosov.
Leading He was sitting under the apple tree.
This is where the idea comes in.
And the fruit over him is already ripe,
Gravitating towards the Earth with all its mass.
The birds fell silent, silence.
Distant lights lit up
And a ripe cloud of the moon
It hung in the sky and shone.
He thought, and the moon is spinning
With the Earth, the Sun went around.
Things invisible connection
She showed up that night.
Here he looked at the sky ...
But the branch trembled - and now
An apple fell to the ground...
Presenter Who is the hero of these poetic lines? Answer: Isaac Newton
Demonstration of entertaining experiments.
High school students demonstrate experiments and explain the essence of phenomena.
Dry from water.
We put a coin on the bottom of a plate or saucer, pour some water. How to get a coin without getting your fingers wet? Answer: we light the paper, put it into a glass, turn it upside down and put it on a plate. The air in it heats up, the pressure increases, and part of the air comes out. The air remaining in the glass cools after a while, the pressure decreases. Under the action of atmospheric pressure, water enters the glass, freeing the coin
Drawings on milk.
We drip dye into a plate with milk and draw patterns on the milk. If you drop a cotton swab into a plate with a soapy solution that reduces the surface tension of a liquid (milk is a liquid), then the paint moves away from the cotton swab to an area of \u200b\u200bhigher surface tension, creating a bizarre picture of moving colors.
Inertia.
We put a paper ring on the neck of the bottle, and on top of the ring - a stack of coins. With a ruler, we sharply knock out a paper ring from the center. Coins fall by inertia into the bottle.
Sound waves.
A film (ball) is stretched over one of the cans, and foam balls are placed on it. Another tin can is turned upside down and along the bottom with a tapping hammer. The sound propagating in the air vibrates the membrane from the film on which light balls bounce.
Music glasses.
We pour water of different heights into glasses, which sound at different frequencies. (Sound pitch).
Lava lamp.
Pour juice and vegetable oil into a glass. Throwing a tablet of effervescent aspirin, we observe the seething of immiscible liquids of different densities.
Extracurricular activity in physics for students in grades 7-8 .
An evening of entertaining physics.
Target:
to form in students an interest in the study of physics, a scientific outlook, to expand the horizons of students, to develop the need to deepen knowledge.
Equipment:
Thematic newspaper, a colorful ad, portraits of physicists, equipment for demonstrating experiments.
Nature lives according to its own laws.
We study them in order to understand
And it is very important to know and understand the basics,
To apply this knowledge in life.
