Explanatory note.

What I hear - I forget.

What I see - I remember.

What I do - I understand.

Throughout preschool childhood, along with play activities, cognitive activity, which takes place in the form of experimental actions, is of great importance in the development of the child's personality, in the processes of socialization. As he proved, deprivation of the opportunity to experiment, constant restrictions on independent activity at an early and preschool age lead to serious mental disorders that persist for life, negatively affect the development and self-development of the child, and the ability to learn in the future. It is experimentation that is one of the leading activities in young children. Important for a child final result- creation of a database about the world. And he strives to achieve it at any cost.

It is no secret to anyone that a preschooler is by nature a researcher. Conscious experimentation as a way of knowing the world, starting at about the age of five, persists throughout life. That is why he is involved in the research search almost constantly. This is his normal, natural state. Already at a younger preschool age, learning about the world around him, the child strives not only to examine the object, but also to touch it with his hands, tongue, sniff, knock. At an older age, many children think about such physical phenomena as water freezing in winter, why a light bulb lights up, what everything is made of, etc. In everyday life, children often experiment with various substances themselves, trying to learn something new. But the danger of such “amateur activity” lies in the fact that the preschooler is not yet familiar with the laws of mixing substances, elementary rules security. The experiment, specially organized by the teacher, is safe for the child and at the same time introduces the various properties of the surrounding objects, the laws of the life of nature and the need to take them into account in one's own life. The value of a real experiment, in contrast to a mental one, lies in the fact that the sides of an object or phenomenon of reality hidden from direct observation are visually revealed; develops the child's ability to define a problem and independently choose ways to solve it; a subjectively new product is created.

Experimentation has always been considered effective way teaching children. And, probably, the way out is in one thing - in the widespread introduction of the method of organized and controlled children's experimentation at home and in kindergarten, individual and collective, in all activities.

Communicating with your children age group, I noted that children are interested in why it snows in winter and rains in summer, why a light is on, why not all objects are attracted to a magnet, etc. Children have a lot of questions that they cannot answer on their own. In order to maintain interest in experimental activities, to expand the knowledge of children, I decided to open the "School of Wizards", where in the joint research activities of an adult with children (experiments, experiments), the child will be given the opportunity to study the world around him, make his own discoveries and inventions.

Set a goal:

Creation of conditions for the development of search - cognitive activity children 5-7 years old as the basis of intellectual - personal, creative development.

The development in preschool children of the prerequisites for dialectical thinking, that is, the ability to see the diversity of the world in a system of interconnections and interdependencies, which, in turn, contributes to the manifestation of creative abilities.

2. Development of one's own cognitive experience in a generalized form with the help of visual aids (standards, symbols, conditional substitutes, models).

3. Expanding the prospects for search and cognitive activity by including children in mental, modeling, transforming actions.

4. Maintaining children's initiative, ingenuity, inquisitiveness, independence, evaluative and critical attitude to the world.

The program "Physics for kids" was made taking into account children's interests and opportunities. The program is based on methodological recommendations for conducting classes using experimentation, and methodological developments"Organization of experimental activities of preschoolers", "Children's experimentation", "Unexplored nearby". The program is designed for children aged 5 to 7 years. To study the cognitive abilities of children, I use the methods "Little Explorer" edited, "Choosing Activities", "Joys and Sorrows" edited.

In other words, this program is not an artificial superstructure, and therefore it naturally and organically integrates into a holistic pedagogical process.

Classes with children are held once a week, lasting 20 minutes. A total of 32 classes per year. Diagnostics was carried out 2 times a year: introductory - October, final May. To study the cognitive abilities of children, I use the methods "Little Explorer" edited, "Choosing Activities", "Joys and Sorrows" edited. What allows you to draw conclusions about how children are able to observe, ask questions, classify, draw conclusions and conclusions, prove and defend their ideas.

In this program, a series of classes has been developed on the topics: “What is everything made of?” (acquaintance with glass, plastic, iron, paper); acquaintance with the physical phenomena "Properties of water", "Magnetism", "Electricity". A feature of the course is the allocation of special time for classes in the "School of Wizards" circle, aimed at developing the basic skills and abilities necessary in a research search.

Abstracts of classes.

What is everything made of? Three states of matter and water.

Target. The development of children's curiosity, their ability to compare, analyze, generalize, establish cause-and-effect relationships and draw conclusions.

Tasks:

- develop elementary ideas about what bodies are made of and how they can change;

To acquaint children with the concepts of "solid body", "liquid", "gas" and their difference from each other;

Using water as an example, explain that matter exists in three states.

Material and equipment:

- tinted liquid in a transparent glass;

Water, ice in molds;

alcohol lamp;

Schemes for the construction of matter in the solid, liquid and gaseous state Experiments:

1. Pour water into ice cube trays and freeze it in the refrigerator or outside on a frosty day.

2. Simulation of three states of matter:

Holding hands tightly, snuggle up to each other, depict particles of a solid body;

Easily holding hands, stand at a short distance from each other - "liquid";

Freely spread throughout the group, like "gas".

3. Two children (one with gloves, the other not) are invited to pick up ice cubes and watch how the ice melts and turns into water. Compare who will melt the ice faster. Find the cause of ice melting and different melting rates.

DIV_ADBLOCK791">

Water spills because its particles, although connected to each other, are not as strong as in solids.

The particles of salt in the water are distributed among the particles of water, and they become invisible, but they have not gone anywhere, so the water is salty.

Theme “Liquid. Properties of water.

Target. To develop the cognitive interest of the child in the process of experimenting with water.

DIV_ADBLOCK792">

6. Take a glass of clean water and smell it. Does she have a smell?

7. Pour some water into a plate and heat it on the flame of an alcohol lamp. What happened? Where did the water from the bowl go? What property of water was discovered?

8. Draw up diagrams of the experiments done.

Conclusions:

1. The first property of water: pushes out lighter objects.

2. It is easier to swim in salt water, because the body is supported not only by water, but also by particles of salt dissolved in it.

3. If you put pebbles into a glass of water, the water level rises. This means that water flows around the pebbles, and does not penetrate into them.

4. As a result of the dissolution of sugar, salt, manganese crystals in water, solutions are obtained (sweet, salty, manganese). We discovered another property of water: a solvent.

5. Comparison of the liquid of water and oil showed that oil is a more viscous liquid.

6. Clean water is odorless, tap water smells like bleach, soda smells like berries, etc. So the water may or may not have an odor. The smell is given to it by various substances dissolved in it.

7. If you pour some water into a plate and heat it up, the water will evaporate and turn into gas. We found that when heated, a liquid turns into a gas.

8. It is difficult to find a place on earth where there would be no water. Water is everywhere and not only in the oceans and seas, in rivers and lakes. Water is also found in the earth. In any stone, in its smallest cracks, there is water. There is a lot of water in living organisms - in every plant, in every animal. Water makes up more than half of the body by weight. There is also water in the air. Water is used by man for drinking and washing, for irrigating fields, orchards and orchards. A lot of water goes into production. Water wealth must be preserved and protected.

Theme "Gas. Air Properties»

Target. Development of the ability to establish cause-and-effect relationships based on an elementary experiment and draw conclusions.

Tasks:

- to clarify the concepts of children that air is not "invisible", but a real-life gas;

To expand children's ideas about the importance of air in human life;

To form children's ideas about oxygen and carbon dioxide;

Clarify ideas about the importance of plants in the life of the planet, develop ecological consciousness.

Experiments:

3. Inflate a flat bike tire. What made her resilient?

4. Experience "Bubbles - rescuers." Fill a glass three-quarters full with carbonated water and immediately throw in small pieces of plasticine. The pieces should be the size of rice grains. Wait a bit and watch. Explain the results.

5. Explain why the swimming circle is filled with air?

6. Put the plastic bottle in the refrigerator. When she cool, put on her neck balloon ik. Put the bottle in the bowl hot water. What happens to the ball and why?

7. Attach a small piece of paper to the bottom of the glass with a piece of plasticine. Turn the glass over, lower it into a basin of water. The sheet of paper is dry. Explain why.

8. Games with balloons and soap bubbles.

Conclusions:

1. Air is not "invisible". Its movement can be felt by fanning in the heat with a fan.

2. An empty bottle is not empty - there is air in it. When the bottle is lowered into a basin of water, the air bubbles rise to the surface because the gas is lighter than the liquid.

3. A bicycle tire is inflated with air, and it is he who makes it elastic. Bubbles form on the plasticine. Pieces of plasticine rise to the surface, turn over and again go to the bottom, where bubbles begin to cling to them again, but in larger numbers. Soda contains carbon dioxide, which creates bubbles. At first, plasticine balls sink because their weight is greater than the buoyancy force. Gas bubbles are like small balloons. They reduce the weight of plasticine so that it can float to the surface. On the surface, the bubbles burst, carbon dioxide mixes with the surrounding air, and the plasticine balls again go to the bottom, where it sticks to them again. a large number of bubbles.

4. The circle for swimming is filled with air, because the gas is lighter than liquid, which means it will support the circle, and with it the person on the surface of the sea or river.

5. The balloon begins to inflate, because the gas in the balloon warms up and expands, the air in the balloon becomes crowded. Gas expands when heated and contracts when cooled.

6. The air that was in the glass did not allow the sheet of paper to get wet. So the glass is not empty, but filled with air.

7. Playing with balloons and soap bubbles proves that the air is light. The balls bounce up easily, and bubble can be moved even by simply breathing.

Theme "Interaction and transition of matter from one type to another (heating and cooling, combustion, water cycle in nature)".

Target. To develop the logical thinking of children, cognitive activity, the ability to establish cause-and-effect relationships.

Tasks:

Demonstrate to children how water heats up, how heat circulates in a room, and lead to an independent conclusion about the water cycle in nature;

To consolidate ideas about the expansion of bodies when heated and the use of this property by a person;

Encourage children to reason about the benefits of expanding bodies when heated (in a thermometer) and its possible danger;

- to clarify children's ideas about burning, to remind them of the need to always follow safety rules;

To form children's ideas that warm air rises;

Improve the speech of children, broaden their horizons, the ability to establish cause-and-effect relationships

Experiments:

1. Put an open plastic bottle in the refrigerator. When she's cool enough, put on her neck balloon. Then put the bottle in a bowl of hot water. What happens to the ball and why?

2. Measure the temperature of hot and cold water. Explain how a thermometer works.

3. Light a match, a candle, examine the flame. What is left of the fire? Explain the danger of fires.

4. Lower and raise the burning candle in the opening of the open door. Explain why the flame of a candle deviates towards the bottom of the room, and at the top - towards the street.

5. Name the main types of precipitation. Why does it snow in winter and rain in summer? What happens to snow in spring? Where does the water that falls on the ground go?

Conclusions:

1. When the water and air in the bottle are heated, the ball itself begins to inflate. This means that when heated, the body expands.

2. The thermometer works on the principle of thermal expansion.

3. As a result of burning, coal remained from the match, the candle melted and the paraffin dripped. After burning leaves, paper, ash also remains. Fire is dangerous during a fire, it destroys houses, even cities. In the hearth, fire brings warmth and comfort.

4. Cold air in the room goes down and spreads along the floor, while warm air rises up, so the candle deviates down into the room, and up towards the room.

5. From the surface of the oceans, seas, rivers and land, water turns into a light invisible vapor and rises. But the higher from the surface of the Earth, the colder the air, and the water vapor cools down, turns into the smallest droplets of water or the smallest pieces of ice. They form clouds. From the clouds, water in the form of snow or rain falls back to the Earth's surface. On land, this water replenishes the rivers, and the rivers carry it to the ocean. So on earth there is a constant cycle of water in nature.

Topic "Magnet and its properties"

Target. Development cognitive activity child in the process of getting to know the hidden properties of the magnet.

Tasks:

Introduce children to the concept of "magnet", "magnetism":

To form ideas about the properties of a magnet:

To update children's knowledge about the use of the properties of a magnet by a person.

Experiments:

1. « Draws a magnet. This experiment demonstrates the pattern that magnetic fields form around magnets of various shapes.

Pour iron filings into a paper cup. Put the magnets on the table. Cover the magnets with a piece of paper. Sprinkle a thin layer of iron filings on the paper. Consider the resulting patterns.

2. "Soaring plane". Show the children how to use a magnet to hang paper airplane in the air.

Cut a wing 3 cm long from a napkin. Pierce it with a pin in the middle to make an airplane. Tie a thread to the pin head. Put the magnet on the edge of the table so that one end of it goes beyond the edge, and put the airplane on this end. Slowly pull the thread until the plane hangs in the air. What happened?

Conclusions:

1. A magnetic field is the space around a magnet in which magnetic attraction affects the movement of metal objects. Getting there, the iron filings are attracted to the magnet - the closer, the stronger. A round magnet has the same field on all sides, but at the ends of a rectangular magnet it is always stronger than in the middle.

2. The aircraft stays in the air as long as it is close to the magnet. The attractive force of a magnet depends on how ordered the magnetic clusters of atoms are, which behave like small magnets. Before the pin touched the magnet, the atoms in the pin were in disorder. The number of atoms that gather in groups and line up in a straight line in a pin depends on the strength of the magnet. Like a magnet, a pin has the properties of a magnet. They are attracted to each other with sufficient force to overcome Earth gravity and force the plane to be in a "suspended" state

Theme “Electric current. Types of electricity.

Target. The development of cognitive activity of children in the process of acquaintance with the phenomenon of electricity.

Tasks:

Introduce children to the concept of "electricity", electric current;

Explain the nature of lightning;

To form the basics of safety when interacting with electricity.

Experiments:

1. Rub the balloon against your hair. What happened?

2. "Electric comb". Measure and cut off a strip of paper (7 * 20 cm) from a napkin. Cut long thin strips on paper, leaving the edge untouched. Comb quickly (hair should be clean and dry). Bring the comb close to the paper strips, but do not touch them.

3. Click. The experiment is carried out in order to acquaint children with the fact that charged particles make sound. Cut a strip from the napkin (3 * 20 cm). Attach the paper clip to the table with plasticine so that it is in a vertical position. Wrap the wool around the plastic and quickly pull the plastic through the fabric. Do this three times. Quickly bring the piece of plastic up to the top of the paperclip. What will you hear?

Conclusions:

1. Hair rises - electrified .

2. Paper strips reach for the comb. When we comb our hair, the charged particles seem to be erased from the hair and fall on the comb. The half of the comb that touched the hair received a charge. The paper strip is attracted to the comb because it also has a charge.

Good afternoon dear parents! You probably know that the whole world is organized according to physical laws, and we, without noticing it ourselves, meet with their manifestations every day. Is the kid already bombarding you with hundreds of questions about the world around you? Entertaining physics for children is your lifesaver, which is important to introduce the child to at the peak of his interest. Then this subject in the future will never become boring and difficult for the child.

We will tell you about what physics is through the eyes of a child, what it gives the baby and how to answer the most tricky questions. We will also dispel the myth that this is a very complex and incomprehensible science.

What does physics give children?

Getting acquainted with the laws of nature from an early age, the baby will be able to:

• satisfy your boundless curiosity;
• open the mind;
• understand the regularity and logic of natural phenomena;
• gain basic knowledge for the further development of their abilities;
• love the subject of "physics" in school, or at least not consider it too difficult.

Kid and physics: acquaintance is inevitable

Seeing a lot of interesting things around, the child seeks to satisfy his curiosity. Often preschool children ask questions like:

• "What is a rainbow?" Explain to the baby that after rain, small droplets of water remain in the air. The sunbeams that pass through them separate White color rays for 7 colors: red, orange, yellow, green, blue, indigo and violet.
• "Why doesn't the plane crash?" Tell that the plane flies because it has wings like birds. He also has an engine that creates a strong wind. And the wind pushes the plane forward. Show with an example paper airplane: The harder you push him, the farther he can fly.
• Why did water turn to ice? Tell your child that water can turn into steam and into ice. It all depends on whether it's hot or cold. If you place a spoon in a stream of steam emanating from the spout of a boiling kettle, then the baby will see droplets of water on it. He will make sure that it is the same substance. Collect water in a small tray, or rather, place a small toy there and put it in the freezer. When bathing, take out an ice cube and give it to your baby. Say that the water was so cold that it shrank and became hard. And in order for it to become the same, it needs to be warmed up again. Let the child dip the ice into a warm bath and see for yourself.
• "Why did the apple fall and not fly into the sky?" Explain that our planet Earth has magical powers. It attracts everything that is on it: people, houses, cars, and any other objects. If you throw the ball high, high, then the Earth will still pull it back.
• "Why do we hear echoes?" Because sound is an invisible wave. It spreads through the air. If an obstacle is encountered on its way, then the wave hits it and returns back. Therefore, we hear a sound that we did not utter.
• "Why paper boat does not sink, but the coin sinks? Because all objects and substances are made up of small particles - molecules. If the molecules are close to each other, then the object has a greater density, and if the molecules are further apart, then the density will be less. The density of water is greater than the density of paper, so the water holds the boat on its surface. With a coin, it's the other way around.
• Why does water put out fire? Because air is needed for combustion, and water blocks the access of air to a burning object. Water from contact with a hot object quickly heats up and turns into steam. She takes the heat from the fire, thereby depriving him of his strength. You can also put out the fire with sand.

We hear hundreds and thousands of similar questions. This means that the child's desire to learn physical laws is natural and inevitable.

How to maintain interest?

Physics is the science that will interest the baby itself, because it is everywhere. We can only maintain his curiosity and introduce him closer. How to do it?

Tell the kid that physics is:

• A science that has attracted many scientists around the world over the years. Thanks to their discoveries, we humans have performed a variety of miracles, which until recently seemed like a real fantasy. Cars and ships, airplanes and computers, mobile communications and the Internet - all this and much more was invented thanks to physics.
• The most important science. Many other sciences are based on it: chemistry, biology, psychology and others. Physics studies the properties of solids, liquids and vapors so that people can use them for their own benefit.
• Science of nature. You are also a part of this world. Do you want to know more about yourself and the environment you live in?

Don't worry if you don't remember physical laws or don't know how to tell your baby about them in an accessible way. There is a mass of literature for children that explains the basic concepts of physics in an understandable language:

• Y. Perelman "Entertaining Physics". For children from 6 years old.
• L. Sikoruk "Physics for kids". For children 5-8 years old.
• D. Macauley "How it all works." For children from 6 to 12 years old.
• E. Kachur. "Fascinating physics" For children 5-8 years old.
• A. Nikonov “Physics on the fingers. For children and parents who want to explain to children. For elementary and middle school students.

Do not wait until your student brings a physics textbook from school. Introduce him to this science earlier in a relaxed atmosphere. Educational cartoons will help you with this:

• "Fixies";
• "Physics for the little ones";
• Hello atom!

To understand physics is to understand life itself

So, down with the stereotypes that physics can only submit to a few. Let's answer briefly how to instill a baby's interest in this science:

• Answer all questions about the environment in plain language. If you're not ready to answer right now, say so and take the time to look for an answer.
• Do not be afraid of the concepts of "molecule", "atom", "weight", "mass", "friction force" and so on.
• Tell the kid that until quite recently people lived without phones, computers and other achievements of civilization. All this became possible thanks to scientists who worked hard on sensational discoveries in the field of physics.
• Read special literature, watch educational cartoons and videos with your child.
• Back up your conversations with engaging ones.

We believe that even if you did not like physics at school, you can change your attitude towards this science and interest your child. We wish you good luck in this matter, and see you soon!

This book is the result of work on a series of television programs "Physics for Kids", created on Novosibirsk television. The programs aroused great interest among children and parents. I received a lot of letters from them with answers to tasks, with stories about the experiments and observations that the children carried out on their own initiative, with questions that had to be answered in the next program.

By profession, I am not a physicist, but a cameraman, but my interest in physics and my passion for it appeared in my childhood. I owe this to my father, who taught me everything that is told in this book. The book is not a textbook. This is a popular presentation of some of the questions studied by the science of physics. "Physics for Toddlers" can be read in a family with older preschoolers and younger students, as well as used for classes in kindergarten and for extracurricular activities at school.

The main goal of the book is to show children that the world around them is cognizable, that all natural phenomena can be scientifically explained. Reading a book should encourage the child to independent observations and experiments, to games similar to those that the characters in the book are busy with.

You should not read the book "drunkenly", there will be little benefit from such reading. It is best to read one story at a time, since each story introduces complex physical phenomena that are not always easy for kids to understand. After reading, be sure to help the child conduct the experiments and observations described in the story, ask questions and discuss the answers to them with the baby. This will help the child to assimilate the knowledge gained and will contribute to the development of his logical thinking, curiosity and ingenuity.

All experiments should be carried out under adult supervision. This is necessary, firstly, for the successful and correct conduct of experiments, and Secondly to comply with safety regulations. Adults should be especially attentive to the experiments described in the sections: “Light phenomena”, “Inertia and jet propulsion”, “Electricity and magnetism”. Acquaintance with physics should be a pleasant and joyful affair. Therefore, it is not necessary to force the child to study in those cases when he is not disposed to engage in physics specifically.

Studying with a book should not be likened to a school lesson. The more relaxed the game of "experiments" is, the better for the cause. In the stories for reading, a lot of secondary information is deliberately omitted in order not to clutter up the main idea of ​​the story with an abundance of facts and help the child understand the very essence of the phenomena. Therefore, detailed comments are printed after each story. Here adults can find some tips on the technique of the experiment and refresh their knowledge of physics. For those who have studied physics for a long time and have little knowledge of it, this material may not be enough. In this case, we advise you to turn to school textbooks in physics. In working with the book, proceed from your experience and the relationships that have developed with children. You know your kids best. They are accustomed to you and your form of communication with them.

THE MAIN THING IS A CREATIVE APPROACH AND RESPECT TO THE INTERNAL WORLD OF THE CHILD. SINCERELY WISH YOU SUCCESS!

Guys, we put our soul into the site. Thanks for that
for discovering this beauty. Thanks for the inspiration and goosebumps.
Join us at Facebook And In contact with

There are very simple experiments that children remember for the rest of their lives. The guys may not fully understand why this is all happening, but when time passes and they find themselves in a lesson in physics or chemistry, a very clear example will surely pop up in their memory.

website collected 7 interesting experiments that children will remember. Everything you need for these experiments is at your fingertips.

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, simple 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.

Many people think that science is boring and dreary. So says the one who has not seen the science shows from "Eureka". What happens in our "lessons"? No cramming, boring formulas and a sour expression on the face of a desk mate. Children like our science, all experiments and experiments, they love our science, our science gives joy and stimulates further knowledge of complex subjects.

Try it yourself, to conduct entertaining experiments in physics for children at home. It will be fun, and most importantly, very informative. your child in game form get acquainted with the laws of physics, and it has been proven that in the game, children quickly and easily learn the material and remember for a long time.

Entertaining experiments in physics that should be shown to children at home

Simple entertaining experiments in physics that children will remember for a lifetime. Everything you need to conduct these experiments is at your fingertips. So, forward to scientific discoveries!

A ball that doesn't burn!

Props: 2 balloons, candle, matches, water.

Interesting experience: We inflate the first balloon and hold it over a candle to demonstrate to the kids that the balloon will burst from the fire.

Pour plain tap water into the second ball, tie it up and bring the candles to the fire again. And about a miracle! What do we see? The ball does not burst!

The water that is in the balloon absorbs the heat generated by the candle, and therefore the balloon does not burn, therefore, does not burst.

Wonder Pencils

Requisites: plastic bag, ordinary sharpened pencils, water.

Interesting experience: Pour water into a plastic bag - not full, half.

In the place where the bag is filled with water, we pierce the bag through with pencils. What do we see? In places of a puncture - the package does not leak. Why? And, if you do the opposite: first pierce the bag, and then pour water into it, the water will flow through the holes.

How the "miracle" happens: explanation: When polyethylene breaks, its molecules are attracted closer to each other. In our experiment, the polyethylene is pulled around the pencils and keeps the water from leaking.

Non-popping ball

Requisites: balloon, wooden skewer and dishwashing liquid.

Interesting experience: Lubricate the top and bottom of the ball with dishwashing liquid, pierce with a skewer, starting from the bottom.

How the "miracle" happens: explanation: And the secret of this “trick” is simple. To save a whole ball, you need to know where to pierce - at the points of least tension, which are located at the bottom and at the top of the ball.

"Cauliflower

Requisites: 4 ordinary glasses of water, bright food coloring, cabbage leaves or white flowers.

Interesting experience: We add food coloring of any color to each glass and put one leaf of cabbage or a flower in colored water. We leave the "bouquet" for the night. And in the morning... we will see that the cabbage leaves or flowers have become different colors.

How the "miracle" happens: explanation: Plants absorb water to nourish their flowers and leaves. This is due to the capillary effect, in which water itself fills the thin tubes inside the plants. By sucking in the tinted water, the leaves and color change their color.

The egg that can swim

Requisites: 2 eggs, 2 cups of water, salt.

Interesting experience: Carefully place the egg in a glass of plain clean water. We see: it drowned, sank to the bottom (if not, the egg is rotten and it is better to throw it away).
But in the second glass, pour warm water and stir 4-5 tablespoons of salt in it. We wait until the water has cooled, then lower the second egg into the salt water. And what do we see now? The egg floats on the surface and does not sink! Why?

How the "miracle" happens: explanation: It's all about density! The average density of an egg is much greater than the density of plain water, so the egg "sinks". And the density of the saline solution is greater, and therefore the egg “floats”.

Delicious Experiment: Crystal Candy

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

Interesting experience: Take a quarter cup of water, add 2 tablespoons of sugar, boil the syrup. At the same time, pour a little sugar onto thick paper. Then dip a wooden skewer into the syrup and collect sugar with it.

Let the sticks dry overnight.

In the morning we dissolve 5 glasses of sugar in two glasses of water, leave the syrup to cool for 15 minutes, but not much, otherwise the crystals will not “grow”. Then pour the syrup into jars and add multi-colored food coloring. We lower the skewers with sugar into jars so that they do not touch either the walls or the bottom (you can use a clothespin). What's next? And then we observe the process of crystal growth, we are waiting for the result in order to ... eat!

How the “miracle” happens: explanation: As soon as the water begins to cool, the solubility of sugar decreases and it precipitates, settling on the walls of the vessel and on a skewer with a seed of sugar grains.

"Eureka"! Science without boredom!

There is another option to motivate children to study science - order a science show at the Evrika Development Center. Oh, what's not here!

Show program "Fun Kitchen"

Here, the kids are waiting for exciting experiments with those things and products that are available in any kitchen. The kids will try to drown the tangerine; make drawings on milk, check the egg for freshness, and also find out why milk is useful.

"Tricks"

This program contains experiments that at first glance seem like real magic tricks, but in fact they are all explained with the help of science. The kids will find out: why the balloon over the candle does not burst; what makes an egg float, why a balloon sticks to a wall... and other interesting experiments.

"Entertaining physics"

Does air weigh, why does a fur coat warm, what is common between the experiment with a candle and the shape of the wing of birds and airplanes, can a piece of fabric hold water, can a eggshell a whole elephant, these and other questions will be answered by the kids by becoming a participant in the show "Entertaining Physics" from "Eureka".

These Entertaining experiments in physics for schoolchildren can be carried out in the classroom to draw students' attention to the phenomenon being studied, while repeating and consolidating educational material: they deepen and expand the knowledge of schoolchildren, contribute to the development of logical thinking, instill interest in the subject.

It Matters: Science Show Safety

• The main part of the props and consumables is purchased directly from specialized stores of manufacturing companies in the United States, and therefore you can be sure of their quality and safety;
• Center child development"Eureka" non-science shows of toxic or other materials harmful to children's health, easily breakable objects, lighters and other "harmful and dangerous";
• Before ordering scientific shows, each client can find out detailed description ongoing experiments, and, if necessary, sensible explanations;
• Before the start of the science shows, the children are instructed about the rules of conduct at the Show, and professional hosts make sure that these rules are not violated during the show.
