Entertaining atom physics for children 10 years old. How to explain physics to a child without leaving the kitchen? Didactic game "Sinking, not sinking"

ABOUT "THREAKER" AND "BEEPER"

Tanya was preparing dinner in the kitchen, Irishka was reading a book, and Lena had nothing to do. He walked over to the drafting table. On it lay a T-square - long

and a thin ruler for drawing. Lyonya moved the T-Square so that one end of it hung from the table, and pulled it - the T-Square swayed. Lenya made the end shorter and pulled again - the T-square shook faster. Lenya made the end even shorter, pulled, and how the T-square buzzed!

Tanya came from the kitchen, went up to the table, turned the T-square in her hands. Then she put it to the edge of the table, pressed it with her palm and pulled the tip - the T-square buzzed.

Well, of course, if it’s trembling, it means it’s buzzing, ”said Tanya. She made the tip shorter, tugged - the T-square trembled very quickly and buzzed in a thin voice. I made the tip longer - the reyshina shook more slowly and buzzed in an angry voice.

Lenya and Irishka followed very closely what Tanya was doing, and finally Lenya said:

It turns out that the shorter the tip of the T-series, the thinner the sound, and the longer the tip, the more angry the sound?

It turns out so, - Tanya agreed. - And here's what you can think of ... Is there a wire?

Yes, - said Lenya and brought a thin wire. Tanya hooked one end of the wire to the desk drawer and pulled it lightly. After that, she pulled the wire in the middle - the wire buzzed. Tanya pulled the wire tighter and pulled again - the wire squeaked thinly. Tanya began to tighten the wire now more strongly, now weaker, from this the wire squealed now in a thin, now angry voice. Suddenly Irishka ran to the children's room. From there she returned with a violin bow. Irishka began to lead the bow along the wire, and Tanya pulled the wire harder, then weaker. And everyone heard that they were getting a song: “Chizhik-pyzhik, where ... have you ... been? ..”

There was such laughter and joy! And when they calmed down, Tanya said to the children:

Touch your neck lightly with your fingers. Now scream!

And the children screamed loudly. They scream and feel their throats tremble.

By the way, you can also do everything that Tanya, Irishka and Lenya did.

When conducting the experiments described in the story, be sure to draw the child's attention to the fact that only trembling objects sound. The child may ask: why do not all trembling objects sound? For example, if you shake your hand, you will not hear anything. The fact is that our ear hears sound only if the frequency of the object's vibrations is more than 20, but less than 16 thousand vibrations per second. Moreover, the higher the frequency of oscillation, the higher the sound that we hear. It is necessary to explain to the children that thick "angry" voices are called low. Bears, hippos, tigers have low voices... The lowest male voice is called bass. The lowest female voice is the contralto.

Experience with a T-square can be replaced with experience with a student ruler. It is necessary to press the ruler against the table strongly, so that when trembling, the pressed end does not knock on the table, otherwise this may give the child a wrong idea about the causes of the sound. It is necessary to ensure that the ruler makes a velvety sound, reminiscent of the sound of a double bass when it is played pizzicato (plucked).

An experiment with a wire and a bow can also be carried out without a bow, playing pizzicato on it. In order for the wire to make sounds of different heights, it must be pulled with different strengths. After some practice, you will surely be able to perform simple melodies. It is very important that this experience is repeated by children.

MATCH PHONE

Once a fitter came and began to install the phone. When he finished work, Lenya said, looking at a brand new phone:

Here we would like this!

And who did I give this phone to? Now this phone is yours.

We don’t need one like that, we need our own, so that I can call Irishka from the factory to the hospital.

Where is the hospital and the factory? - the fitter asked. The hospital is on the couch, - said Lenya, - and the factory is in our room. sch

So-so ... - the fitter thought. - Are there any matches?

And the threads?

There are also threads.

The fitter threaded the needle, then emptied the matches out of the box and pierced the bottom of the box with the needle. After that, he pulled the thread from the needle. And to

the tip of the thread did not jump out of the box, I tied a match to it. To the second end of the thread, the fitter attached the second matchbox in the same way. When he finished this work, he handed both boxes to the children and said:

You, Irinushka, stay here

Lyonya, run to your factory.

Irishka took her box and waited, and Lenya ran to the children's room. There he stopped, and the thread between the boxes stretched like a string. Lyonya put the box to his lips, and Irishka put his to his ear.

Irishka, can you hear me?

I can hear you well even without a phone.

And you close the other ear with your hand, - said the fitter.

Irishka covered her other ear with her palm.

Irishka! Leon screamed again.

Now you can hear it well on the phone, - Irishka said and put her box to her lips.

Lyonya!.. Oh!

What's "oops"? - asked the fitter.

The finger is ticklish, - said Irishka.

What tickles him?

The bottom of the box, - says Irishka.

So it's trembling? - asked the fitter.

Yes, - agreed Irishka.

The bottom trembles and makes the thread tremble, - added the fitter.

And I know! Lyonya screamed.

What do you know? - the fitter asked.

A shiver runs along the thread to my box and makes its bottom tremble, and this again makes a sound.

Right. Well, when we talk without a match phone, how does the sound of my voice reach your ear? After all, there is no thread, what is trembling?

The children thought. They thought and thought, and here Irishka says: You know, it's the air that trembles. Put your fingers to your throat. Installer attached.

Now say "ah."

A-ah-ah, - said the fitter.

Do you feel your throat trembling?

Feel.

Well, when we speak, the throat trembles, and the air begins to tremble from it, from this, waves run through the air, like through water, only they are not visible in the air, but you can hear them.

Well, well done, - the fitter said and smiled at the children in parting.

Make a phone out of string and matchboxes. Talk to someone on this phone, and then touch the thread with your finger. Will they hear you?

Why, if you touch the thread with your finger, the sound does not reach the second box?

When making a toy phone, you need to keep in mind that the thread stretched between the two boxes should not touch any objects, including the fingers that hold the box. It is necessary to explain to the children that if the thread touches an object, then the trembling of the thread is transmitted to this object and does not spread further. Therefore, no sound is heard in the second box.

Instead of matchboxes, you can take any other boxes of suitable sizes: from powder, tooth powder, paper clips. One boy wrote to me that he used, instead of a thread, a thin wire without soft insulation, forty steps long. He did this experiment with friends on the street, and it was very well audible.

You can show children that sound travels not only along a string, but also in other objects. If, while swimming in the river, you lower your head into the water so that your ears are also immersed, you can hear the sound of people splashing nearby, the boat’s engine running far away, etc.

Sound travels well in metals. To verify this, you can knock on the heating battery. In the neighboring apartment, this sound will be heard very well. Of course, this experience should not be abused, since the sound is transmitted through pipes not only to the apartment where you need it, but to all other apartments too.

An interesting experience was described in a letter from one girl. Her mother threw a pebble into the bathtub filled with water, and the girl, putting her ear to the bathtub wall, listened to the waves spreading in circles begin to splash against the bathtub wall. The result was a visual picture explaining how sound waves propagate and reach the ear.

It must be kept in mind that in this experiment the child will hear the sound of the falling stone twice. First, he will hear a sound that was transmitted by sound waves, which in water, as well as in air, are invisible and travel with great speed. Then the child will see ordinary waves on the surface of the water, which spread in circles in all directions from the place of the fall, and, finally, when these waves reach the wall of the bath, he will hear them. It is necessary to explain to the child that real sound waves in water, as well as in air, are not visible, and you did the experiment with waves on the surface of water in order to better understand how sound propagates in all directions in air, in water and other substances.

HOW TO MAKE SOUND LOUDER

One day Lenya invented a new “trembling machine”. It was a hairbrush. You pull a tooth, and the comb squeaks. It's just too quiet. Lenya brought the comb to his ear, now it is well and loudly heard, but here's the trouble: Lenya hears well, but Irishka, who draws at the table, does not hear at all. Lenya put a comb to his forehead, again only he hears well. Finally, I thought to put the comb on the table. He pulled the clove, and the comb tinkled loudly. Irishka looked up from the drawing and looked at what Lenya was doing. And Lenya, let's put the comb to everything that gets in your eyes: to the window, to the door, to the piano ... And every time he puts the comb to a solid object, the comb squeaks loudly, and when it lifts it into the air, it squeaks weakly.

Tanya also became interested in this discovery. She rolled up a mouthpiece from a sheet of paper and says to Lena:

Put a comb to the mouthpiece.

Lenya put a comb to the mouthpiece, pulled the clove, and the comb squeaked loudly.

Why is it louder with a horn? Tanya asked.

Children don't know.

Here Tanya says:

When a clove trembles, it sways the air around it, but the clove is small and sways little air, so the sound turns out to be quiet.

Here Irishka said:

When we put a comb to the horn and pulled the clove, the horn also trembled, but it is large and sways a lot of air, so the sound turns out louder.

What, and the table trembles when we put a comb to it? - asked Lenya.

Put your finger on the table, - asked Tanya.

Lyonya put it on, and Tanya put a comb next to it.

Tanya fumbled for a clove and asks:

Well? Is the table shaking or not?

Shaking a little! Lenya was surprised.

Irishka, of course, immediately began to explain:

Although the table trembled slightly from the comb, it is large and sways the air much more than the tooth of the comb, so the sound is loud.

After everyone understood why the sound is loud, the children took a stick and nailed a carnation at its ends. A wire was pulled over the studs, to the lower end of which a horn was attached. Tanya brought a violin bow, handed it to Irishka and said:

We got an amazing cello.

Tanya sat down at the piano; Irishka took the bow in her hand, and with the fingers of the other hand she began to press the string-wire; Lenya held the mouthpiece so that it would not fall to the floor. And all together began to play the song "Chizhik-Pyzhik." The sound of a homemade cello is like the roar of a hungry bear that has been awakened in winter. The cello growls, but it still turns out well - loud and funny!

Spring break is approaching, and many parents are wondering: what to do with children? Home experiments in physics - for example, from the book “Experiments of Tom Tit. Amazing Mechanics is a great pastime for younger students. Especially if the result is such a useful thing as an air gun, and the laws of pneumatics become clearer.

Sarbakan - air gun

Air is widely used in various modern technical devices. Vacuum cleaners work with it, car tires are pumped with it, and they are also used in wind guns instead of gunpowder.

The blowgun, or sarbakan, is an ancient hunting weapon that was sometimes used for military purposes. It is a tube 2-2.5 meters long, from which, under the action of air exhaled by the shooter, miniature arrows are ejected. In South America, on the islands of Indonesia and in some other places, the sarbakan is still used for hunting. You can make a miniature of such a blowgun yourself.

What will be required:

plastic, metal or glass tube;
needles or sewing pins;
drawing or painting brushes;
insulating tape;
scissors and threads;
small feathers;
foam rubber;
matches.

Experience. The body for the sarbican will be a plastic, metal or glass tube 20-40 centimeters long and with an inner diameter of 10-15 millimeters. A suitable tube can be made from the third leg of a telescopic rod or ski pole. The tube can be rolled up from a sheet of thick paper, wrapped on the outside with electrical tape for strength.

Now one of the ways you need to make arrows.

First way. Take a bunch of hair, for example, from a drawing or paint brush, tie it tightly with a thread from one end. Then insert a needle or pin into the resulting knot. Secure the structure by wrapping it with electrical tape.

The second way. Instead of hair, you can use small feathers, such as those stuffed with pillows. Take a few feathers and wrap their outer ends with electrical tape directly to the needle. Using scissors, cut the edges of the feathers to the diameter of the tube.

The third way. The arrow can be made with a match shaft, and the “feathering” can be made of foam rubber. To do this, stick the end of a match in the center of a foam rubber cube measuring 15-20 millimeters. Then tie the foam rubber to the matchstick by the edge. Using scissors, shape a piece of foam rubber into a cone shape with a diameter equal to the inner diameter of the sarbican tube. Attach a needle or pin to the opposite end of the match with electrical tape.

Put the arrow into the tube with the point forward, put the tube to your closed lips, and opening your lips, blow sharply.

Result. The arrow will fly out of the tube and fly 4-5 meters. If you take a longer tube, then with a little practice and choosing the optimal size and mass of arrows, you can hit the target from a distance of 10-15 meters.

Explanation. The air blown out by you is forced to exit through the narrow channel of the tube. At the same time, the speed of its movement greatly increases. And since there is an arrow in the tube that prevents the free movement of air, it also contracts - energy accumulates in it. Compression and accelerated air movement accelerate the arrow and give it enough kinetic energy to fly some distance. However, due to friction against the air, the energy of the flying arrow is gradually consumed, and it flies.

Pneumatic lift

You've no doubt had to lie on an air mattress. The air it is filled with is compressed and easily supports your weight. Compressed air has a lot of internal energy and exerts pressure on surrounding objects. Any engineer will tell you that air is a wonderful worker. With its help, conveyors, presses, lifting and many other machines work. They are called pneumatic. This word comes from the ancient Greek "pneumotikos" - "inflated with air." You can test the power of compressed air and make the simplest pneumatic lift from simple improvised items.

What will be required:

thick plastic bag;
two or three heavy books.

Experience. Place two or three heavy books on the table, for example in the shape of the letter "T", as shown in the figure. Try blowing on them to make them fall or roll over. No matter how hard you try, you're unlikely to succeed. However, the power of your breath is still enough to solve this seemingly difficult task. Pneumatics should be called for help. To do this, the air of breathing must be “caught” and “locked”, that is, made compressed.

Place a bag of dense polyethylene under the books (it must be intact). Press the open end of the bag to your mouth with your hand and start blowing. Take your time, blow slowly, because the air will not go anywhere from the bag. Watch what happens.

Result. The package will gradually inflate, lift the books higher and higher, and finally knock them over.

Explanation. When air is compressed, the number of its particles (molecules) per unit volume increases. Molecules often hit the walls of the volume in which it is compressed (in this case, the package). This means that the pressure from the side of the air on the walls increases, and the more, the more the air is compressed. The pressure is expressed by the force applied to the unit area of the wall. And in this case, the force of air pressure on the walls of the bag becomes greater than the force of gravity acting on the books, and the books rise.

How to explain physics to a child without leaving the kitchen?

If school physics suddenly becomes an unbearable burden for children, not only tutors, but also parents can help them! Explain physical phenomena to the child using simple examples that can be seen in everyday life, conduct some simple physical experiments and experiments with him. How to do this - we will demonstrate further, citing as an example familiar processes that can be observed even in your own kitchen.

Light refraction

The first thing that physics can be interesting for children is optical physical phenomena, in particular, the refraction of light rays. And if you have a vase with flowers in your kitchen, or a transparent cup with a spoon, then this phenomenon is clearly observed in it. It can be seen that a teaspoon lowered into a cup, passing through the water, seems to shift and continue under water at a different angle - it looks as if the spoon has broken. Or another example: if you pour water into a saucepan and put, say, peas on its bottom, then it will seem larger than it really is.

This is the phenomenon of light refraction, when a light beam, passing through the boundary of two different media, changes its direction and angle of incidence. Moreover, the angle of incidence is greater, the greater the angle of refraction. But if the light beam is directed perpendicular to this boundary, then there will be no refraction. In the case of a spoon and a cup, the beam of light passes at an acute angle from the air into the water, and the water acts as a lens that refracts the light rays reflected in the spoon.

Change in the state of aggregation of matter

Aggregate state - the state of matter under certain conditions, in a specific range of pressure and temperature, which determines the properties of the substance, its ability to maintain shape and volume, or change them. These states traditionally include solid, liquid and gaseous.

But it sounds boring, so physics for kids comes to the rescue. It is easy to observe the change in aggregate states using the example of ordinary water. First check the child: if you spill some water on the floor and do not wipe it off, will the puddle stay there forever or not? What happens to water if you put it in the refrigerator? This is the state of aggregation of matter! It turns out that such familiar physical phenomena in the kitchen almost every day happen under our noses.

And why is this happening? It's not magic, it's physics! Water is a liquid, and liquid is an intermediate state between solid and gaseous substances. The solid state, in this case ice, is formed when water is subjected to freezing temperature (below 0°C) and a gas - water vapor - is formed at the boiling point (100°C). At temperatures from 0 ° C to 100 ° C, water is in a liquid state - and all because the intermolecular attraction at such marks is not as strong as in the solid state, but not as weak as in the gaseous state.

The transition of water into steam, that is, evaporation, occurs when water molecules from an open surface receive energy - solar or from room temperature, and begin to move randomly. The attraction between them weakens. As the temperature decreases, the kinetic energy of the molecules decreases, and the attractive forces increase.

Thermal conductivity of bodies

The next physical phenomenon that physics considers for children using examples from life is thermal conductivity, that is, the ability of various material bodies to heat exchange, transfer energy. But how to explain this process to a child? Yes, at least on the example of heating soup in a saucepan, or water in a kettle!

Imagine: we put the soup on the stove. The temperature of the pot will begin to rise, and due to the temperature difference, the movement of particles will increase, which will facilitate the transfer of heat from the fire to the dishes, and from the heated dishes to the soup. But not all bodies have the same thermal conductivity: for example, metals have a higher thermal conductivity than, say, wood and air. Therefore, we heat the soup in a metal pan so that it heats up faster - however, it will cool down, it will quickly. However, if you stir the soup with a wooden spoon / spatula, then it will slowly heat up, having low thermal conductivity, but due to this it will cool slowly.

Physics for children has another such interesting thing regarding thermal conductivity as convection - a type of heat transfer in which energy is transferred in a flow-like manner, either naturally or by force. That is, when the soup just stands on the stove, it heats up naturally, but when it is stirred with a spoon, convection will be forced.

Diffusion

Diffusion is one of the most interesting and understandable physical phenomena that physics can tell, but it can also be difficult for children at times. Meanwhile, we constantly observe this process in life, in particular, in the kitchen. Diffusion is called mutual penetration, mixing of two substances, similar in structure, to a homogeneous state. Diffusion occurs due to the kinetic energy of the molecules of those substances - it is she who sets them in motion.

One of the most accessible examples of the diffusion of liquids that physics knows for children is brewing tea in boiling water. Let the child throw a tea bag or a handful of tea leaves into the water without stirring - then you can watch how the tea leaves mix with clean water. And the hotter the water, the faster the mixing process will take place.

And in solids, salting vegetables for the winter can be an example for children: salt crystals, once in the water for the future brine, will disintegrate, forming chloride and sodium ions, which will eventually penetrate between the molecules of salted vegetables, be it tomatoes, cucumbers or even mushrooms. This type of diffusion is the slowest.

But the fastest diffusion occurs in gases. Children know exactly how quickly the delicious smell of mom's cooking from the kitchen spreads around the house - this is how food aromas mix with air molecules in the room.

Law of Archimedes

This law is also called the law of hydrostatics. According to him, a buoyant force acts on a body immersed in a liquid (the Archimedes force), which is equal to the mass of the liquid that can fill the volume of this body. This means that a body with a density lower than the density of the liquid will be pushed out of it, and with a density higher, it will sink and sink, while pushing out as much liquid as corresponds to its volume.

Such physics will become clearer for children as soon as you remind them about cooking - for example, about boiling chicken. To cook a bird, mother does not collect a full pot of water, but approximately three-quarters, depending on the volume of the carcass. When we lower the chicken into the water, we will notice how the water rises to the edges of the dish, much closer than it was before. Archimedes' law in all its glory!

refractory ball

It will take: 2 balls, candle, matches, water.

Experience: Inflate a balloon and hold it over a lighted candle to show the children that the balloon will burst from fire. Then pour plain tap water into the second ball, tie it up and bring it to the candle again. It turns out that with water the ball can easily withstand the flame of a candle.

Explanation: The water in the balloon absorbs the heat generated by the candle. Therefore, the ball itself will not burn and, therefore, will not burst.

Pencils

You will need: plastic bag, pencils, water.

Experience: Pour water halfway into a plastic bag. We pierce the bag through with a pencil in the place where it is filled with water.

Explanation: If you pierce a plastic bag and then pour water into it, it will pour out through the holes. But if you first fill the bag halfway with water and then pierce it with a sharp object so that the object remains stuck in the bag, then almost no water will flow out through these holes. This is due to the fact that when polyethylene breaks, its molecules are attracted closer to each other. In our case, the polyethylene is pulled around the pencils.

Non-popping ball

You will need: balloon, wooden skewer and some dishwashing liquid.

Experience: Lubricate the top and bottom with the product and pierce the ball, starting from the bottom.

Explanation: The secret of this trick is simple. In order to save the ball, you need to pierce it at the points of least tension, and they are located at the bottom and at the top of the ball.

Cauliflower

It will take: 4 cups of water, food coloring, cabbage leaves or white flowers.

Experience: Add food coloring of any color to each glass and put one leaf or flower into the water. Leave them overnight. In the morning you will see that they have turned into different colors.

Explanation: Plants absorb water and thus nourish their flowers and leaves. This is due to the capillary effect, in which the water itself tends to fill the thin tubes inside the plants. This is how flowers, grass, and large trees feed. By sucking in tinted water, they change their color.

floating egg

It will take: 2 eggs, 2 glasses of water, salt.

Experience: Gently place the egg in a glass of plain clean water. As expected, it will sink to the bottom (if not, the egg may be rotten and should not be returned to the refrigerator). Pour warm water into the second glass and stir 4-5 tablespoons of salt in it. For the purity of the experiment, you can wait until the water cools down. Then dip the second egg into the water. It will float near the surface.

Explanation: It's all about density. The average density of an egg is much greater than that of plain water, so the egg sinks down. And the density of the saline solution is higher, and therefore the egg rises.

crystal lollipops

It will take: 2 cups water, 5 cups sugar, wooden sticks for mini skewers, thick paper, transparent glasses, saucepan, food coloring.

Experience: In a quarter cup of water, boil sugar syrup with a couple of tablespoons of sugar. Sprinkle some sugar on paper. Then you need to dip the stick in syrup and collect the sugar with it. Next, distribute them evenly on a stick.

Leave the sticks to dry overnight. In the morning, dissolve 5 cups of sugar in 2 cups of water on fire. You can leave the syrup to cool for 15 minutes, but it should not cool down much, otherwise the crystals will not grow. Then pour it into jars and add different food colors. Lower the prepared sticks into a jar of syrup so that they do not touch the walls and bottom of the jar, a clothespin will help with this.

Explanation: As the water cools, the solubility of sugar decreases, and it begins to precipitate and settle on the walls of the vessel and on your stick with a seed of sugar grains.

lit match

Need: Matches, flashlight.

Experience: Light a match and hold it at a distance of 10-15 centimeters from the wall. Shine a flashlight on the match and you will see that only your hand and the match itself are reflected on the wall. It would seem obvious, but I never thought about it.

Explanation: Fire does not cast shadows, as it does not prevent light from passing through it.

Today marks the 110th anniversary of the birth of the Russian physicist Matvey Petrovich Bronstein, the author of the popular science books "Rays of X", "Solar Matter", etc. His contribution to the creation of the quantum theory of gravity and the popularization of science was highly appreciated by domestic and foreign scientists.

In honor of this event, we have prepared for you a small selection of books on the topic "Physics" for children from preschool to senior school age. Alexander Nikonov, Yakov Perelman, Elena Kachur - this is an incomplete list of authors whose books are included in our thematic selection.

8 books on the topic

"Physics for children"

Matthew Bronstein. solar substance. X rays. Inventors of the radiotelegraph

" Book "Solar Matter", written by the untimely deceased talented physicist Matvei Petrovich Bronstein, is an outstanding phenomenon in the field of world popular literature.

It is written so simply and fascinatingly that reading it is perhaps equally interesting for any reader from a schoolboy to a professional physicist. Once you start it, it's hard to keep from reading until end ". (Lev Landau, 1956)

The book is really written in clear and extremely entertaining language, while there are no oversimplifications in the presentation of the material. Bronstein's books can be considered the gold standard of non-fiction for children.

Alexander Nikonov. Physics at your fingertips. For children and parents who want to explain to children

Do you understand the theory of Stephen Hawking and the theory of relativity? Do you know and can you explain the basics of quantum physics in an accessible way? Do you want to understand the most fashionable science of the 21st century?
