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 will get acquainted with the laws of physics in a playful way, 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 friend to friend. 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 brine more, 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 experiences in physics for schoolchildren can be carried out in the classroom to draw students' attention to the phenomenon under study, while repeating and consolidating educational material: they deepen and expand the knowledge of schoolchildren, contribute to the development 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;
• Children's Development Center "Eureka" non-scientific 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.

Nothing in life is better than your own experience.

Scott W.

At school and at home, we got acquainted with many physical phenomena and we wanted to make home-made devices, equipment and conduct experiments. All our experiments allow us to get deeper knowledge the world and in particular physics. We describe the process of making equipment for the experiment, the principle of operation and the physical law or phenomenon demonstrated by this device. The experiments carried out interested students from other classes.

Target: make a device from available improvised means to demonstrate a physical phenomenon and use it to tell about a physical phenomenon.

Hypothesis: made devices, demonstrations will help to know physics deeper.

created home-made devices that demonstrate the dependence of liquid pressure on the height of the liquid column, Pascal's law.

We liked to study pressure, make home-made devices, conduct experiments. But there are many interesting things in the world that you can still learn, so in the future:

We will continue to study this interesting science

We hope that our classmates will be interested in this problem, and we will try to help them.

In the future, we will conduct new experiments.

Conclusion

It is interesting to watch the experience conducted by the teacher. Conducting it yourself is doubly interesting.

And to conduct an experiment with a device made and designed by one's own hands is very big interest for the whole class. In such experiments, it is easy to establish a relationship and draw a conclusion about how a given installation works.

Conducting these experiments is not difficult and interesting. They are safe, simple and useful. New research ahead!

1. INTRODUCTION

Physics is not only scientific books and complex laws, not only huge laboratories. Physics is also interesting experiments and entertaining experiments. Physics is tricks shown in a circle of friends, these are funny stories and funny homemade toys.

Most importantly, any available material can be used for physical experiments.

Physical experiments can be done with balls, glasses, syringes, pencils, straws, coins, needles, etc.

Experiments increase interest in the study of physics, develop thinking, teach how to apply theoretical knowledge to explain various physical phenomena occurring in the surrounding world.

When conducting experiments, it is necessary not only to draw up a plan for its implementation, but also to determine methods for obtaining certain data, to independently assemble installations and even design the necessary devices for reproducing this or that phenomenon.

But, unfortunately, due to the overload of educational material in physics lessons, insufficient attention is paid to entertaining experiments, much attention is paid to theory and problem solving.

Therefore, it was decided to conduct research work on the topic "Entertaining experiments in physics from improvised materials."

The objectives of the research work are as follows:

1. Master the methods of physical research, master the skills of correct observation and the technique of physical experiment.
2. Organization of independent work with various literature and other sources of information, collection, analysis and generalization of material on the topic of research work.
3. Teach students to apply scientific knowledge to explain physical phenomena.
4. To instill a love for physics in school students, focusing their attention on understanding the laws of nature, and not on their mechanical memorization.
5. Replenishment of the physics classroom with home-made devices made from improvised materials.

When choosing a research topic, we proceeded from the following principles:

1. Subjectivity – the chosen topic corresponds to our interests.
2. Objectivity - the topic we have chosen is relevant and important in scientific and practical terms.
3. feasibility - the tasks and goals set by us in the work are real and feasible.

1. MAIN PART.

The research work was carried out according to the following scheme:

1. Formulation of the problem.
2. The study of information from various sources on this issue.
3. The choice of research methods and practical mastery of them.
4. Collection of own material - acquisition of improvised materials, conducting experiments.
5. Analysis and generalization.
6. Formulation of conclusions.

During the research work, the followingphysical research methods:

I. Physical experience

The experiment consisted of the following stages:

1. Understanding the conditions of experience.

This stage provides for acquaintance with the conditions of the experiment, determining the list of necessary improvised instruments and materials and safe conditions during the experiment.

1. Drawing up a sequence of actions.

At this stage, the order of the experiment was outlined, if necessary, new materials were added.

1. Conducting an experiment.

II. Observation

When observing phenomena occurring in experience, we turned Special attention on changes in physical characteristics (pressure, volume, area, temperature, direction of light propagation, etc.), while we were able to detect regular relationships between various physical quantities.

III. Modeling.

Modeling is the basis of any physical research. During our experiments, we simulatedisothermal compression of air, propagation of light in various media, reflection and absorption of electromagnetic waves, electrization of bodies during friction.

In total, we modeled, conducted and scientifically explained 24 entertaining physical experiments.

As a result of the research work, it is possible to makethe following conclusions:

1. AT various sources you can find information and come up with many entertaining physical experiments performed with the help of improvised equipment.
2. Entertaining experiments and home-made physical devices increase the range of demonstrations of physical phenomena.
3. Entertaining experiments allow you to test the laws of physics and theoretical hypotheses that are of fundamental importance for science.

TOPIC "ATMOSPHERE PRESSURE"

Experience number 1. "The balloon doesn't deflate"

Materials: A three-liter glass jar with a lid, a straw for a cocktail, a rubber ball, thread, plasticine, cloves.

Sequencing

Using a carnation, make 2 holes in the lid of the jar - one central, the other at a short distance from the central one. Pass a straw through the central hole and seal the hole with plasticine. Tie a rubber ball to the end of the straw with a thread, close the lid glass jar, while the end of the straw with the ball should be inside the jar. To eliminate the movement of air, close the place of contact between the lid and the jar with plasticine. Inflate a rubber balloon through a straw, the balloon will deflate. And now inflate the balloon and close the second hole in the lid with plasticine, the balloon is first blown away, and then it stops blowing off. Why?

scientific explanation

In the first case, when the hole is open, the pressure inside the can is equal to the air pressure inside the ball, therefore, under the action of the elastic force of the stretched rubber, the ball is blown away. In the second case, when the hole is closed, the air does not leave the can, as the balloon is blown off, the air volume increases, the air pressure decreases and becomes less than the air pressure inside the balloon, and the balloon stops blowing off.

The following experiments were carried out on this topic:

Experience number 2. "Pressure balance".

Experience number 3. "The Air Kicks"

Experience number 4. "glued glass"

Experience number 5. "Moving Banana"

THEME "WARMTH"

Experience number 1. "Soap bubble"

Materials: Small medicine bottle with stopper, clean stem from ballpoint pen or a straw from a cocktail, a glass of hot water, a pipette, soapy water, plasticine.

Sequencing

Make a thin hole in the stopper of the medicine bottle and insert a clean ballpoint pen or straw into it. Cover the place where the rod entered the cork with plasticine. With a pipette, fill the rod with soapy water, lower the bottle into a glass of hot water. Soap bubbles will rise from the outer end of the rod. Why?

scientific explanation

When the bottle is heated in a glass of hot water, the air inside the bottle heats up, its volume increases, and soap bubbles are inflated.

On the topic "Heat" the following experiments were carried out:

Experience number 2. "Fireproof Scarf"

Experience number 3. "Ice Doesn't Melt"

TOPIC "ELECTRICITY AND MAGNETISM"

Experience number 1. "Current Meter - Multimeter"

Materials: 10 meters of 24 gauge insulated copper wire (diameter 0.5mm, cross section 0.2mm 2 ), wire stripper, wide adhesive tape, sewing needle, thread, strong bar magnet, juice can, electrochemical cell "D".

Sequencing

Strip the wire from both ends of the insulation. Wind the wire around the can in tight turns, leaving the ends of the wire 30 cm free. Remove the resulting coil from the can. To prevent the coil from falling apart, wrap it with adhesive tape in several places. Attach the coil vertically to the table with a large piece of tape. Magnetize the sewing needle by passing it over the magnet at least four times in one direction. Tie the needle with thread in the middle so that the needle hangs in balance. Stick the free end of the thread inside the spool. The magnetized needle should hang quietly inside the coil. Connect the free ends of the wire to the positive and negative terminals of the galvanic cell. What happened? Now reverse the polarity. What happened?

scientific explanation

A magnetic field arises around a coil with current, and a magnetic field also arises around a magnetized needle. The magnetic field of a coil with current acts on a magnetized needle and turns it. If you change the polarity, then the direction of the current is reversed, the needle turns in the opposite direction.

In addition, the following experiments were carried out on this topic:

Experience number 2. "Static glue".

Experience number 3. "Fruit Battery"

Experience number 4. "Anti-Gravity Disks"

THEME "LIGHT AND SOUND"

Experience number 1. "Soap Spectrum"

Materials: Soap solution, a pipe cleaner (or a piece of thick wire), a deep plate, a flashlight, sticky tape, a sheet of white paper.

Sequencing

Bend the pipe brush (or a piece of thick wire) so that it forms a loop. Don't forget to make a small handle to make it easier to hold. Pour the soap solution into a bowl. Immerse the loop in the soap solution and let it soak thoroughly with the soap solution. After a few minutes, carefully remove it. What do you see? Are colors visible? Attach a sheet of white paper to the wall with sticky tape. Turn off the lights in the room. Turn on the flashlight and direct its beam at the loop of soapy suds. Position the lantern so that the loop casts a shadow on the paper. Describe the full shadow.

scientific explanation

White light is a complex light, it consists of 7 colors - red, orange, yellow, green, blue, indigo, violet. This phenomenon is called light interference. When passing through a soap film, white light breaks up into separate colors, different light waves on the screen form a rainbow pattern, which is called a continuous spectrum.

On the topic "Light and sound" the following experiments were carried out and described:

Experience number 2. "On the edge of the abyss".

Experience number 3. "Joke's sake"

Experience number 4. "Remote control"

Experience number 5. "Copier"

Experience number 6. "Appearing out of nowhere"

Experience number 7. "Colored top"

Experience number 8. "Jumping Grains"

Experience number 9. "Sound Sound"

Experience number 10. "Blowing out the sound"

Experience number 11. "Intercom"

Experience number 12. "Crowing glass"

1. CONCLUSION

Analyzing the results of entertaining experiments, we were convinced that school knowledge is quite applicable to solving practical issues.

With the help of experiments, observations and measurements, the relationships between various physical quantities were investigated

Volume and pressure of gases

Pressure and temperature of gases

The number of turns and the magnitude magnetic field around the current coil

gravity and atmospheric pressure

The direction of light propagation and the properties of a transparent medium.

All the phenomena observed during entertaining experiments have a scientific explanation, for this we used the fundamental laws of physics and the properties of the matter around us - Newton's II law, the law of conservation of energy, the law of straightness of light propagation, reflection, refraction, dispersion and interference of light, reflection and absorption of electromagnetic waves.

In accordance with the task set, all experiments were carried out using only cheap, small-sized improvised materials; during their implementation, 8 home-made devices were made, including a magnetic needle, a copier, a fruit battery, a current meter - a multimeter, an intercom, safe, visual experiments, simple in design.
