Fun experiences. Experiments for children at home. Experience "The Mighty Power of Breath"

Today, there are a huge number of educational games for children. But conducting various experiments in a homely atmosphere will leave an indelible impression on the younger generation. With a minimum set of items, it is possible to perform many experiments, which in the mind of the child will be perceived as a focus.

Experiments for children "Invisible ink"

To create this magical experience for kids, you will need the following ingredients:

Lemon juice - 1 teaspoon;
Drinking water - 0.5 tablespoon;
Cup;
Double-sided cotton swab;
Blank sheet of paper.

Actions to commit a secret message are carried out in the following order:

Squeezed lemon juice and water are poured into a glass. Everything is thoroughly mixed.
One side of the cotton swab should be used as a writing instrument. It is dipped in a lemon solution of water and the necessary text is applied to them on a blank sheet of paper.
After the secret information has completely dried, the sheet with the message must be heated. For the experience, you will need an included table lamp.
Under influence lighting device, encrypted letters will begin to appear, such an experience at home for your child will be an amazing knowledge of chemical laws.

Experiments for children "Inflating a balloon with a lemon"

As necessary items for conducting such an experiment you will need:

Glass empty bottle;
Balloon;
Scotch;
Clean glass;
Baking soda - 1 dessert spoon;
1 glass of pure water;
Food vinegar - 3 large spoons;
Juice of 1 lemon;
Funnel.

Such a test is carried out in several stages:

Prepared soda is added to a bottle of water.
Vinegar and lemon juice mixed in a glass. Then, using a funnel, the acidic mixture is poured into a bottle with soda and water.
With quick actions, put the ball on the neck of the bottle. And immediately wrap the edges with tape. This is necessary so that the air does not come out.
The ingredients put into the bottle create the necessary chemical reaction. Their end result is the selection carbon dioxide, which by its properties creates pressure inside this structure.
It is this forced action that inflates balloon.

Experiments for children "Space rocket launch"

For this experience and creating a natural release of the lethal vehicle, you will need the following items:

colored paper;
Bottle with pressed cork;
PVA glue;
Scissors;
Drinking water - 0.5 cups;
Funnel;
Juice squeezed from one lemon;
Baking soda - 0.5 teaspoon;
Toilet paper, small size;
Threads.

The launch of the rocket model is carried out in a strict sequence of actions:

The cork will serve as the body of the spacecraft. It should not close the neck of the bottle too tightly. Glass containers are a kind of platform for starting.
Using scissors and colorful paper, you need to form wings for the rocket. Fix with glue. The result should be a mock-up of an aircraft that easily enters the neck of the bottle.
With the help of a funnel, glass container pour water and lemon juice. Then the resulting mixture is mixed and waits for its finest hour.
Into a piece toilet paper baking soda is poured and wrapped with threads. The glomerulus should turn out to be of such a size that it can easily get into the prepared bottle without much effort.
A place to launch a spaceship must be thought out in advance. Since its rapid flight can destroy the chandelier on the ceiling.
Next, drop a lump of soda powder into a bottle of solution. And put a model of a rocket on the neck. But at the same time, the entry of the lethal vehicle into the launch turbine should not be too tight.
After a few seconds of waiting, you can almost see a real space launch, a great experience for children.

Experiments for children "Toothpick command"

During this experience, the child may well feel like a magician. In order for this miracle to happen, you need to arm yourself with items such as:

Toothpicks;
shallow cup of water;
Rafinated sugar;
Dishwashing liquid.

Via minimum set and several actions you can conduct an experiment:

Spread the toothpicks on the water, in the form of sun rays.
Then, slowly lower a piece of refined sugar into the water into the center formed.
With this action, you can draw the toothpicks to the center of the bowl and the sugar lump.
And if you remove the sugar from the container, and put a small drop on this place detergent, then the rays will begin to move away to the edges of the cup.
The focus of these actions is that sugar, by its properties, sucks in air, thereby attracting nearby objects. A soap solution, on the contrary, repels.

Experience for children "Floating egg"

In order to make the egg float, you will need the following components:

Raw chicken egg;
Container with clean drinking water;
Salt - 1 pack.

First, let's try to drop the egg into raw water. It just sank. Now we take it back and pour salt into the water. That is, we create a strong brine. The next step is to try to make the egg float in salt water. And it really is on the water surface and does not sink. This is due to the fact that salt creates an increased density of water, so this experience is obtained for children.

Experiments for children "Ice fishing"

As a catch, in this experiment for children, there will be a small ice cube. It will be fished out of a glass of water, but the hands will remain dry. Scroll necessary materials described below:

Glass with clean water;
Frozen ice cube;
A few grains of salt;
Thread, no more than one meter long.

When conducting this experiment, it is necessary to carefully monitor everything that happens so as not to miss important details. The procedure for performing the necessary operations is:

A small piece of ice is lowered into a prepared glass of water.
The thread is placed with one end on the edge of the glass, and the other on the ice cube.
Salt granules are sprinkled on the ice where the thread is located. And the time is ticking. The waiting time is 5-10 minutes.
After the time has elapsed, with gentle movements over the edge of the thread, you can get an ice cube. It will be attached to the string.
This is due to salt, which melts the ice. And then pure water only freezes the thread to the ice piece.

Experiments for children "Cold water boils"

To see the boiling bubbles in cold water, participants in the experiments will need components such as:

Glass filled to the top cold water;
Pharmaceutical gum;
Handkerchief.

You need to perform all the tricks of the experiment in the sink and in the appropriate order:

The handkerchief is abundantly moistened with water and squeezed out.
A handkerchief is placed on a glass of water and secured with an elastic band. Moreover, the core of the scarf should touch the water surface.
Turn the prepared glass upside down and hold in one hand. With the other hand, apply light blows to the bottom of the glass. From these actions, the water begins to “boil”, that is, to boil.
This is due to the fact that the fabric of the handkerchief does not allow water to pass from the glass. And upon impact, vacuum air is formed, which enters the water, your child will be delighted.

Experience "Creating a musical instrument"

When creating a musical flute for children at home from improvised materials, you will need items such as:

plastic straw;
Scissors.

The future tool needs to be flattened a little on one side and cut off its side edges. At equal distance from each other, three holes are cut on the surface of the straw. You just need to blow air into it slightly and alternately close the holes. The flute is ready to play music, an excellent experience for developing ear, imagination and logic modeling.

Experience "Bird in a cage"

To perform this experiment, it is necessary to prepare materials:

Scissors;
White cardboard;
Needle and thread;
Compass;
Colour pencils.

Compliance with all stages of this experience will lead to an unforgettable experience of creating a cartoon. To construct it you need:

Using a compass, draw a regular circle on the cardboard and cut it out.
On the sides of the circle, pierce a pair of holes with a needle and pull the threads through them. The length of the threads on both sides should be about half a meter.
On the outside of the cardboard you need to depict an empty cage. And on another small bird that could fit in this cage.
Then, taking the threads from both sides, it is necessary to twist them with rotating movements.
When stretching the twisted ends, they will unwind. And at this moment the child will be able to see the bird that is in the cage.

Experiments for children "Turning a square into a circle"

The focus of this test is the visual effect. For its implementation, materials are needed:

Cardboard;
Ruler;
felt-tip pen;
Pencil.

When performing the transformation trick, it is necessary to cut out a square of the correct shape from cardboard. Then, using a ruler, find the middle of one side. Attach one end to it measuring device, and bring its other end to the corner of the nearest side. Along the formed line, using a felt-tip pen, it is necessary to apply about 30 points.

On a cardboard square, find its middle and pierce it with the sharp tip of a pencil. Cardboard paper should rotate on the pencil without much effort. When the square is rotated, you can see the resulting circle. Although these are just dots on the cardboard, they simply move in a circle and create a circle effect.

Experience "The Mighty Power of Breath"

Any child considers himself strong and courageous. And in order for his confidence in this to be fixed, it is necessary to conduct a similar experiment. For its implementation you will need:

Hangers for clothes;
Thick thread;
Book;
Clothesline.

The implementation of all stages of the experience will lead to excellent mastery results. The implementation of these activities is:

At a pre-selected place, it is necessary to pull the clothesline.
With the help of threads, a book is tied to the shoulders. It should not be in close contact with the hanger, that is, there must be free space between them.
The hanger hook must be hung on a clothesline. The design for the experiment is ready.
Being at a short distance from the device, you need to blow on it with all the available strength. The result of these actions will be only a slight wiggle of the book mechanism.
And if you change the tactics of breathing from the same distance, then the result will not be long in coming. With a slight increase in exhalation of air, the design will begin to deviate. And after you can also slowly blow on the device. That is, the effect of mightiness consists in the lightness and consistency of the breath.

Experiments for children "Record weight"

The materials needed for the experiment for children are used:

small tin cans- 2 pieces;
Paper;
Glass jar, about 1 liter.

The experiment consists of the following steps:

Cans of tin material are placed opposite each other, at an approximate distance of about 30 centimeters.
A prepared sheet of paper is laid on top of them. It creates the appearance of a bridge.
On this laid paper bridge, you need to carefully place the jar. The result of such actions will be the fall of the glass container.
If a paper sheet is folded into the shape of a typical accordion and placed between two tins, then a bridge will also be obtained. But only with enhanced action. Because if you put a jar on this structure, it will not fall, since the bridge does not even bend.

Whichever of these experiments is carried out in the society of children, they will certainly remember its effect for many years to come.

Video "Experiments for children at home"

Friends, good afternoon! Agree, how sometimes it is interesting to surprise our crumbs! They have such a funny reaction to. She shows that they are ready to learn, ready to assimilate new material. The whole world opens at this moment before them and for them! And we, parents, act as real wizards with a hat, from which we “pull out” something amazingly interesting, new and very important!

What will we get out of the "magic" hat today? We have 25 there experimental experiments for children and adults. They will be prepared for babies different ages to get them interested and involved in the process. Some can be carried out without any preparation, with the help of handy tools that each of us has at home. For others, you and I will buy some materials so that everything goes smoothly for us. Well? I wish all of us good luck and forward!

Today will be a real holiday! And in our program:

So let's decorate the holiday by preparing an experiment for birthday, New Year, March 8, etc.

Ice bubbles

What do you think would happen if simple bubbles that crumble in 4 years so loves to inflate, run after them and burst them, inflate them in the cold. Or rather, right into the snowdrift.

I give you a hint:

they will burst immediately!
take off and fly away!
freeze!

Whatever you choose, I say right away, it will surprise you! Can you imagine what will happen to the little one?

But in slow motion - it's just a fairy tale!

I complicate the question. Is it possible to repeat the experience in the summer in order to get a similar option?

Choose answers:

Yes. But you need ice from the fridge.

You know, even though I so want to tell you everything, but that’s exactly what I won’t do! Let there be at least one surprise for you!

Paper vs water

We are waiting for the real experiment. Is it really possible for paper to win over water? This is a challenge for everyone who plays Rock-Paper-Scissors!

What we need:

Paper;
Water in a glass.

Cover the glass. It would be nice if its edges were a little wet, then the paper will stick. Gently turn the glass upside down... No water leaks!

Inflate balloons without breathing?

We have already carried out chemical children's experiences. Remember, there the very first for very small crumbs was a room with vinegar and soda. So, let's continue! And we use the energy, or rather, the air that is released during the reaction for peaceful purposes.

Ingredients:

Soda;
The bottle is plastic;
Vinegar;
Ball.

Pour soda into a bottle and pour 1/3 of vinegar. Shake lightly and quickly pull the ball over the neck. When it inflates, bandage and remove from the bottle.

Such an experience a small one will be able to show even in kindergarten.

Rain from a cloud

We need:

Bank with water;
Shaving foam;
Food coloring (any color, you can use several colors).

We make a cloud of foam. Big and beautiful cloud! Leave it to the best cloud maker, your child 5 years. He will definitely make her real!

photo author

It remains only to distribute the dye over the cloud, and ... drop-drip! Rain is coming!

Rainbow

Maybe, physics children are still unknown. But after they make the Rainbow, they will definitely love this science!

Deep transparent container with water;
Mirror;
Lamp;
paper.

Place a mirror at the bottom of the container. At a slight angle, shine a flashlight on the mirror. It remains to catch the Rainbow on paper.

Even easier is to use a disc and a flashlight.

crystals

There is a similar, only already finished game. But our experience interesting the fact that we ourselves, from the very beginning, will grow crystals from salt in water. To do this, take a thread or wire. And we will hold it for several days in such salty water, where the salt can no longer dissolve, but accumulates in a layer on the wire.

Can be grown from sugar

lava jar

If you add oil to a jar of water, it will all collect on top. It can be tinted with food coloring. But in order for the bright oil to sink to the bottom, you need to pour salt on top of it. Then the oil will settle. But not for long. The salt will gradually dissolve and “release” beautiful droplets of oil. Colored oil rises gradually, as if a mysterious volcano seething inside the jar.

Eruption

For toddlers 7 years it will be very interesting to blow up, demolish, destroy something. In a word, the real element is for them. and therefore we create a real, exploding volcano!

We sculpt from plasticine or make a “mountain” from cardboard. We put a jar inside it. Yes, so that her neck fits the "crater". We fill the jar with soda, dye, warm water and ... vinegar. And everything will begin to “explode, the lava will rush up and flood everything around!

A hole in the bag is not a problem.

This is what convinces book scientific experiments for children and adults Dmitry Mokhov "Simple Science". And we can verify this statement ourselves! First, let's fill the bag with water. and then we pierce it. But what they pierced (a pencil, a toothpick or a pin) will not be removed. Are we running out of water? Checking!

Water that does not spill

Only such water still needs to be made.

We take water, paint and starch (as much as water) and mix. The end result is plain water. Just don't spill it!

"Slippery" egg

In order for the egg to really crawl into the neck of the bottle, it is worth setting fire to a piece of paper and throwing it into the bottle. And cover the hole with an egg. When the fire is out, the egg will slip inside.

snow in summer

This trick is especially interesting to repeat in warm time of the year. Remove the contents of the diapers and soak with water. All! Snow is ready! Now such snow is easy to find in the store in children's toys. Ask the seller for artificial snow. And don't ruin diapers.

moving snakes

To make a moving figure, we need:

Sand;
Alcohol;
Sugar;
Soda;
Fire.

Pour alcohol on a hill of sand and let it soak. Then pour sugar and soda on top, and set fire! Oh what a cheerful this experiment! Kids and adults will love what the snake comes to life!

Of course, this is for older children. Yes, and it looks pretty scary!

battery train

The copper wire, which we twist into an even spiral, will become our tunnel. How? Connect its edges, forming a round tunnel. But before that, we “launch” the battery inside, we only attach neodymium magnets to its edges. And consider yourself a perpetual motion machine! The steam locomotive drove off.

Candle swing

To light both ends of the candle, you need to clean the bottom of it to the wick from wax. Heat the needle over the fire and pierce the candle in the middle with it. Put the candle on 2 glasses so that it rests on the needle. Burn the edges and wiggle slightly. Then the candle itself will swing.

Elephant Tooth Paste

The elephant needs everything big and much. Let's do it! We dissolve potassium permanganate in water. Adding liquid soap. The final ingredient, hydrogen peroxide, turns our mixture into giant elephant paste!

Let's drink a candle

For a greater effect, we color the water in bright color. We put a candle in the middle of the saucer. We set it on fire and cover it with a transparent container. Pour water into a saucer. At first, the water will be around the container, but then everything will soak inside, to the candle.
Oxygen is burned, the pressure inside the glass decreases and

Real chameleon

What will help our chameleon change color? Cunning! Give your toddler 6 years decorate in different colors plastic plate. And you yourself cut out the figure of a chameleon on another plate, similar in shape and size. It remains not to firmly connect both plates in the middle so that the upper one, with a cut out figure, can rotate. Then the color of the animal will always change.

Light up the rainbow

Arrange the Skittles on a plate in a circle. Pour water into the bowl. just wait a bit and get a rainbow!

smoke rings

Cut off the bottom of the plastic bottle. And stretch the edge of the cut balloon to get a membrane, as in the photo. Light the incense stick and place it in the bottle. Close the lid. When there is solid smoke in the jar, unscrew the lid and tap on the membrane. Smoke will come out in rings.

colorful liquid

To make everything look more spectacular, paint the liquid in different colors. Make 2-3 blanks of colored water. pour water of the same color into the bottom of the jar. Then carefully, along the wall with different sides pour vegetable oil. Pour water mixed with alcohol over it.

Egg without shell

Put a raw egg in vinegar for at least a day, some say for a week. And the focus is ready! An egg without a hard shell.
The egg shell is rich in calcium. Vinegar reacts actively with calcium and gradually dissolves it. As a result, the egg is covered with a film, but completely without a shell. It feels like an elastic ball to the touch.
Also, the egg will be larger than its original size, as it will absorb some of the vinegar.

Dancing little men

It's time to mess around! Mix 2 parts cornstarch with 1 part water. Put a bowl of starchy liquid on top of your speakers and turn up the bass!

Decorating the ice

We decorate ice figures of various shapes with the help of food paint mixed with water and salt. Salt corrodes the ice and seeps deep, forming interesting passages. Great idea color therapy.

Launching paper rockets

We free tea bags from tea by cutting off the top. We set fire! Warm air lifts the package!

There are so many experiences that you will definitely find something to do with children, just choose! And don't forget to come back for a new article that you'll find out about if you subscribe! Invite your friends to visit us! And that's all for today! Till!

Entertaining experiments for preschoolers, experiments for children at home, tricks for children, entertaining science ... How to curb the seething energy and indefatigable curiosity of the baby? How to make the most of the inquisitiveness of the child's mind and push the child to explore the world? How to promote the development of a child's creativity? These and other questions certainly arise before parents and educators. In this work, we have collected a large number of a variety of experiences and experiments that can be carried out with children to expand their understanding of the world, for intellectual and creative development child. The described experiments do not require any special training and almost no material costs.

How to pierce a balloon without harm to it?

The child knows that if the balloon is pierced, it will burst. Stick on the ball on both sides of a piece of adhesive tape. And now you can safely pierce the ball through the tape without any harm to it.

"Submarine" No. 1. Submarine from grapes

Grab a glass of fresh sparkling water or lemonade and toss a grape into it. It is slightly heavier than water and will sink to the bottom. But gas bubbles, similar to small ones, will immediately begin to sit on it. air balloons. Soon there will be so many of them that the grape will pop up.

But on the surface, the bubbles will burst and the gas will escape. The heavy grape will again sink to the bottom. Here it will again be covered with gas bubbles and rise again. This will continue several times until the water "exhales". According to this principle, it rises and rises real boat. And the fish have a swim bladder. When she needs to dive, the muscles contract, squeezing the bubble. Its volume decreases, the fish goes down. And you have to get up - the muscles relax, dissolve the bubble. It increases and the fish floats up.

"Submarine" No. 2. Egg submarine

Take 3 jars: two half-liter and one liter. Fill one jar with clean water and dip a raw egg into it. It will drown.

Pour a strong solution of table salt into the second jar (2 tablespoons per 0.5 l of water). Dip the second egg there - it will float. This is because salt water is heavier, so it is easier to swim in the sea than in a river.

Now put an egg on the bottom of a liter jar. Gradually adding water from both small jars in turn, you can get a solution in which the egg will neither float nor sink. It will be held, as if suspended, in the middle of the solution.

When the experiment is done, you can show the focus. By adding salt water, you will ensure that the egg will float. Adding fresh water - that the egg will sink. Externally salty and fresh water is not different from each other and it will look amazing.

How to get a coin out of the water without getting your hands wet? How to get out of the water dry?

Put the coin on the bottom of the plate and fill it with water. How to take it out without getting your hands wet? The plate must not be tilted. Fold a small piece of newspaper into a ball, set fire to it, throw it into a half-liter jar and immediately put it down with the hole in the water next to the coin. The fire will go out. The heated air will come out of the can, and due to the difference atmospheric pressure inside the jar, the water will be drawn into the jar. Now you can take the coin without getting your hands wet.

lotus flowers

Cut flowers with long petals from colored paper. Using a pencil, twist the petals towards the center. And now lower the multi-colored lotuses into the water poured into the basin. Literally before your eyes, the flower petals will begin to bloom. This is because the paper gets wet, becomes gradually heavier and the petals open.

natural magnifier

If you need to make out any small creature, such as a spider, a mosquito or a fly, it is very easy to do this.

Plant the insect in a three-liter jar. Tighten the neck at the top cling film, but do not pull it, but, on the contrary, push it so that a small container forms. Now tie the film with a rope or elastic band, and pour water into the recess. You will get a wonderful magnifying glass through which you can perfectly see the smallest details.

The same effect will be obtained if you look at an object through a jar of water, fixing it on back wall jars with transparent tape.

water candlestick

Take a short stearin candle and a glass of water. Weight the lower end of the candle with a heated nail (if the nail is cold, the candle will crumble) so that only the wick and the very edge of the candle remain above the surface.

The glass of water in which this candle floats will be the candlestick. Light the wick and the candle will burn for quite some time. It seems that it is about to burn down to water and go out. But that won't happen. The candle will burn out almost to the very end. And besides, a candle in such a candlestick will never cause a fire. The wick will be extinguished with water.

How to get drinking water?

Dig a hole in the ground about 25 cm deep and 50 cm in diameter. Place an empty hole in the center of the hole. Plastic container or a wide bowl, put fresh green herbs and leaves around it. Cover the hole with clean plastic wrap and fill its edges with earth so that air does not escape from the pit. Place a stone in the center of the film and lightly press the film over the empty container. The device for collecting water is ready.

Leave your design until the evening. And now carefully shake the earth off the film so that it does not fall into the container (bowl), and look: there is clean water in the bowl.

Where did she come from? Explain to the child what is under the action solar heat grass and leaves began to decompose, releasing heat. Warm air always rises. It settles in the form of evaporation on a cold film and condenses on it in the form of water droplets. This water flowed into your container; remember, you pushed the film a little and put a stone there.

Now you have to come up with interesting story about travelers who went to distant lands and forgot to take water with them, and start an exciting journey.

Miraculous matches

You will need 5 matches.

Break them in the middle, bend them at a right angle and put them on a saucer.

Put a few drops of water on the folds of the matches. Watch. Gradually, the matches will begin to straighten out and form a star.

The reason for this phenomenon, which is called capillarity, is that wood fibers absorb moisture. She crawls further and further along the capillaries. The tree swells, and its surviving fibers "get fat", and they can no longer bend much and begin to straighten out.

Washbasin chief. Making a washbasin is easy

Toddlers have one feature: they always get dirty when there is even the slightest opportunity for that. And the whole day to take a child home to wash is quite troublesome, besides, children do not always want to leave the street. Solving this issue is very simple. Make a simple washbasin with your child.

To do this, you need to take a plastic bottle, on its side surface about 5 cm from the bottom, make a hole with an awl or nail. The work is finished, the washbasin is ready. Plug the hole made with your finger, pour water to the top and close the lid. Slightly unscrewing it, you get a trickle of water by screwing it - you will "close the tap" of your washbasin.

Where did the ink go? transformations

Drop ink or ink into a bottle of water to make the solution a pale blue. There also put a tablet of crushed activated carbon. Close the mouth with your finger and shake the mixture.

She brightens up before her eyes. The fact is that coal absorbs dye molecules with its surface and it is no longer visible.

Making a cloud

Pour into a 3 liter jar hot water(approximately 2.5 cm). Place a few ice cubes on a baking sheet and place it on top of the jar. The air inside the jar, rising up, will cool. The water vapor it contains will condense to form a cloud.

This experiment simulates the formation of clouds during cooling warm air. And where does the rain come from? It turns out that the drops, heated up on the ground, rise up. It gets cold there, and they huddle together, forming clouds. When they meet together, they increase, become heavy and fall to the ground in the form of rain.

I don't believe my hands

Prepare three bowls of water: one with cold water, another with room water, and a third with hot water. Ask the child to put one hand in a bowl of cold water, the other in hot water. After a few minutes, have him submerge both hands in water at room temperature. Ask if she seems hot or cold to him. Why is there a difference in hand feel? Can you always trust your hands?

water suction

Put the flower in water, tinted with any paint. Watch how the color of the flower changes. Explain that the stem has ducts that carry water up to the flower and color it. This phenomenon of water absorption is called osmosis.

Vaults and tunnels

Glue a thin paper tube slightly larger in diameter than a pencil. Insert a pencil into it. Then carefully fill the tube with the pencil with sand so that the ends of the tube come out. Pull out the pencil and you will see that the tube is not crumpled. Sand grains form protective vaults. Insects caught in the sand come out from under the thick layer unharmed.

All equally

Take an ordinary coat hanger, two identical containers (these can also be large or medium disposable cups and even aluminum cans for drinks, however, you need to cut off the cans upper part). In the upper part of the container on the side, opposite each other, make two holes, insert any rope into them and attach it to a hanger, which you hang, for example, on the back of a chair. Balance containers. And now, pour either berries, or sweets, or cookies into such impromptu scales, and then the children will not argue who got more goodies.

"Good boy and roly-poly". Obedient and naughty egg

First, try placing a whole raw egg on the blunt or pointed end. Then start experimenting.

Poke two holes the size of a match head at the ends of the egg and blow out the contents. Rinse the inside thoroughly. Let the shell dry well from the inside for one to two days. After that, close up the hole with plaster, glue with chalk or whitewash so that it becomes invisible.

Fill the shell with clean and dry sand about one quarter. Seal the second hole in the same way as the first. Obedient egg is ready. Now, in order to put it in any position, just shake the egg slightly, holding it in the position that it should take. The grains of sand will move and the placed egg will keep its balance.

To make a “roly-poly” (roly-poly), you need to throw 30-40 pieces of the smallest pellets and pieces of stearin from a candle into the egg instead of sand. Then put the egg on one end and heat it up. The stearin will melt, and when it hardens, it will stick the pellets together and stick them to the shell. Cover the holes in the shell.

The tumbler will be impossible to put down. An obedient egg will stand on the table, and on the edge of the glass, and on the knife handle.

If your child wants to, have them paint both eggs or make funny faces on them.

Boiled or raw?

If there are two eggs on the table, one of which is raw and the other is boiled, how can you determine this? Of course, every housewife will do this with ease, but show this experience to a child - he will be interested.

Of course, he is unlikely to connect this phenomenon with the center of gravity. Explain to him that in a boiled egg the center of gravity is constant, so it spins. And in a raw egg, the internal liquid mass is like a brake, so a raw egg cannot spin.

"Stop, hands up!"

Take a small plastic jar for medicines, vitamins, etc. Pour some water into it, put any effervescent tablet and close it with a lid (non-screw).

Put it on the table, turning it upside down, and wait. The gas released at chemical reaction pills and water, pushes the bottle out, there will be a “roar” and the bottle will be thrown up.

"Magic Mirrors" or 1? 3? 5?

Place two mirrors at an angle greater than 90°. Put one apple in the corner.

This is where it begins, but only begins, a real miracle. There are three apples. And if you gradually reduce the angle between the mirrors, then the number of apples begins to increase.

In other words, the smaller the angle of approach of the mirrors, the more objects will be reflected.

Ask your child if it is possible to make 3, 5, 7 from one apple without using cutting objects. What will he answer you? Now put the above experience.

How to wipe the knee green from the grass?

Take fresh leaves of any green plant, be sure to put them in a thin-walled glass and pour a small amount of vodka. Place the glass in a pot of hot water water bath), but not directly to the bottom, but to some wooden circle. When the water in the saucepan has cooled, remove the leaves from the glass with tweezers. They will discolor, and the vodka will turn emerald green, as chlorophyll, the green dye of plants, has been released from the leaves. It helps plants "eat" solar energy.

This experience will be useful in life. For example, if a child accidentally stains his knees or hands with grass, then you can wipe them off with alcohol or cologne.

Where did the smell go?

Take corn sticks, put them in a jar that has been dripped with cologne, and close it with a tight lid. After 10 minutes, when you open the lid, you will not feel the smell: it was absorbed by the porous substance of the corn sticks. This absorption of color or odor is called adsorption.

What is elasticity?

Take a small rubber ball in one hand, and a plasticine ball of the same size in the other. Drop them to the floor from the same height.

How did the ball and the ball behave, what changes happened to them after the fall? Why does the plasticine not bounce, but the ball bounces, perhaps because it is round, or because it is red, or because it is rubber?

Invite your child to be the ball. Touch the baby's head with your hand, and let him sit down a little, bending his knees, and when you remove your hand, let the child straighten his legs and jump. Let the baby jump like a ball. Then explain to the child that the same thing happens with the ball as with him: he bends his knees, and the ball is pressed a little when it hits the floor, he straightens his knees and bounces, and what is pressed in the ball straightens. The ball is elastic.

A plasticine or wooden ball is not elastic. Tell the child: “I will touch your head with my hand, but don’t bend your knees, don’t be elastic.”

Touch the child's head, and let him not bounce like a wooden ball. If you do not bend your knees, then it is impossible to jump. You can't straighten your knees that haven't been bent. A wooden ball, when it hits the floor, is not pressed in, which means it does not straighten out, so it does not bounce. He's not resilient.

The concept of electric charges

Blow up a small balloon. Rub the ball on wool or fur, and even better on your hair, and you will see how the ball will begin to stick to literally all objects in the room: to the closet, to the wall, and most importantly, to the child.

This is because all objects have a certain electrical charge. As a result of contact between two various materials separation of electrical discharges.

dancing foil

cut into aluminum foil(a shiny chocolate or candy wrapper) in very narrow and long strips. Run the comb through your hair, and then bring it close to the sections.

The stripes will begin to dance. This attracts to each other positive and negative electric charges.

Hanging on the head, or is it possible to hang on the head?

Make a light top out of cardboard by putting it on a thin stick. Sharpen the lower end of the stick, and stick a tailor's pin (with a metal, not a plastic head) deeper into the upper end so that only the head is visible.

Descendants of Sherlock Holmes, or In the Footsteps of Sherlock Holmes

Mix the soot from the stove with talc. Let the child breathe on a finger and press it against a sheet of white paper. Sprinkle this place with the prepared black mixture. Shake the sheet of paper so that the mixture covers well the area where the finger was applied. Pour the rest of the powder back into the jar. There will be a clear fingerprint on the sheet.

This is explained by the fact that we always have a little fat from the subcutaneous glands on our skin. Everything we touch leaves an indelible mark. And the mixture we made sticks well to fat. Thanks to the black soot, it makes the print visible.

Together is more fun

Cut out a circle from thick cardboard, circling the rim of the teacup. On one side, in the left half of the circle, draw a boy figure, and on the other side, a girl figure, which should be located upside down in relation to the boy. Make a small hole on the left and right of the cardboard, insert the elastic bands with loops.

Now stretch the elastic bands in different directions. The cardboard circle will spin quickly, the pictures from different sides will be combined, and you will see two figures standing side by side.

The secret thief of jam. Or maybe it's Carlson?

Grind the pencil lead with a knife. Let the child rub his finger with the prepared powder. Now you need to press your finger to a piece of tape, and stick the tape to white sheet paper - your baby's fingerprint pattern will be visible on it. Now we will find out whose prints were left on the jar of jam. Or maybe it was Carloson who flew in?

Unusual drawing

Give your child a piece of clean, light-colored cloth (white, blue, pink, light green).

Pick the petals off different colors: yellow, orange, red, blue, light blue, and green leaves different shade. Just remember that some plants are poisonous, such as aconite.

Spread this mixture on a cloth placed on cutting board. You can both involuntarily pour petals and leaves, and build a conceived composition. Cover it with plastic wrap, fasten it on the sides with buttons and roll it all out with a rolling pin or tap on the fabric with a hammer. Shake off the used "paints", stretch the fabric over thin plywood and insert it into the frame. The masterpiece of young talent is ready!

It turned out lovely gift mother and grandmother.

Children are always trying to learn something new every day and they always have a lot of questions. They can explain some phenomena, or you can clearly show how this or that thing, this or that phenomenon works. In these experiments, children will not only learn something new, but also learn how to create different crafts, which they can then play with.

1. Experiments for children: lemon volcano

You will need:

– 2 lemons (for 1 volcano)

- baking soda

- food coloring or watercolors

- dishwashing liquid

– wooden stick or spoon (optional)

- tray.

1. Cut off the bottom of the lemon so that it can be placed on flat surface.

2. On the reverse side, cut a piece of lemon as shown in the image.

* You can cut half a lemon and make an open volcano.

3. Take the second lemon, cut it in half and squeeze the juice out of it into a cup. This will be the backup lemon juice.

4. Place the first lemon (with the part cut out) on the tray and spoon "remember" the lemon inside to squeeze out some of the juice. It is important that the juice is inside the lemon.

5. Add food coloring or watercolor to the inside of the lemon, but do not stir.

6. Pour dishwashing liquid inside the lemon.

7. Add a full spoonful to the lemon baking soda. The reaction will start. With a stick or spoon, you can stir everything inside the lemon - the volcano will begin to foam.

8. To make the reaction last longer, you can gradually add more soda, dyes, soap and reserve lemon juice.

2. Home experiments for children: electric eels from chewing worms

You will need:

- 2 glasses

- small capacity

- 4-6 chewing worms

- 3 tablespoons of baking soda

- 1/2 tablespoon of vinegar

– 1 cup of water

- scissors, kitchen or clerical knife.

1. With scissors or a knife, cut lengthwise (just lengthwise - this will not be easy, but be patient) of each worm into 4 (or more) parts.

* The smaller the piece, the better.

* If scissors don't want to cut properly, try washing them with soap and water.

2. Mix water and baking soda in a glass.

3. Add pieces of worms to the solution of water and soda and stir.

4. Leave the worms in the solution for 10-15 minutes.

5. Using a fork, transfer the worm pieces to a small plate.

6. Pour half a spoon of vinegar into an empty glass and start putting worms in it one by one.

* The experiment can be repeated if the worms are washed with plain water. After a few attempts, your worms will begin to dissolve, and then you will have to cut a new batch.

3. Experiments and experiments: a rainbow on paper or how light is reflected on a flat surface

You will need:

- a bowl of water

– clear nail polish

- small pieces of black paper.

1. Add 1-2 drops to a bowl of water clear varnish for nails. See how the varnish disperses through the water.

2. Quickly (after 10 seconds) dip a piece of black paper into the bowl. Take it out and let it dry on a paper towel.

3. After the paper has dried (it happens quickly) start turning the paper and look at the rainbow that is displayed on it.

* To better see the rainbow on paper, look at it under the sun's rays.

4. Experiments at home: a rain cloud in a jar

When small drops of water accumulate in a cloud, they become heavier and heavier. As a result, they will reach such a weight that they can no longer remain in the air and will begin to fall to the ground - this is how rain appears.

This phenomenon can be shown to children with simple materials.

You will need:

- shaving foam

- food coloring.

1. Fill the jar with water.

2. Apply shaving foam on top - it will be a cloud.

3. Let the child begin to drip the food coloring onto the “cloud” until it starts to “rain” – drops of food coloring begin to fall to the bottom of the jar.

During the experiment, explain this phenomenon to the child.

You will need:

– warm water

- sunflower oil

- 4 food colorings

1. Fill the jar 3/4 full with warm water.

2. Take a bowl and mix 3-4 tablespoons of oil and a few drops of food coloring in it. AT this example 1 drop of each of 4 dyes was used - red, yellow, blue and green.

3. Stir the dyes and oil with a fork.

4. Carefully pour the mixture into a jar of warm water.

5. Watch what happens - food coloring will slowly sink through the oil into the water, after which each drop will begin to disperse and mix with other drops.

* Food coloring dissolves in water, but not in oil, because. The density of oil is less than water (which is why it “floats” on water). A drop of dye is heavier than oil, so it will begin to sink until it reaches the water, where it begins to disperse and look like a small firework.

6. Interesting experiences: in a bowl in which colors merge

You will need:

- a paper-cut wheel painted in the colors of the rainbow

- rubber band or thick thread

– cardboard

- glue stick

- scissors

- skewer or screwdriver (to make holes in the paper wheel).

1. Choose and print the two templates you want to use.

2. Take a piece of cardboard and use a glue stick to glue one template to the cardboard.

3. Cut out the glued circle from the cardboard.

4. Glue the second template to the back of the cardboard circle.

5. Use a skewer or screwdriver to make two holes in the circle.

6. Pass the thread through the holes and tie the ends into a knot.

Now you can spin your spinning top and watch how the colors merge on the circles.

7. Experiments for children at home: jellyfish in a jar

You will need:

- a small transparent plastic bag

– transparent plastic bottle

- food coloring

- scissors.

1. Lay the plastic bag on a flat surface and smooth it out.

2. Cut off the bottom and handles of the bag.

3. Cut the bag lengthwise on the right and left so that you have two sheets of polyethylene. You will need one sheet.

4. Find a center polyethylene sheet and fold it like a balloon to make a jellyfish head. Tie the thread around the “neck” of the jellyfish, but not too tight - you need to leave a small hole through which to pour water into the head of the jellyfish.

5. There is a head, now let's move on to the tentacles. Make cuts in the sheet - from the bottom to the head. You need about 8-10 tentacles.

6. Cut each tentacle into 3-4 smaller pieces.

7. Pour some water into the jellyfish's head, leaving room for air so the jellyfish can "float" in the bottle.

8. Fill the bottle with water and put your jellyfish in it.

9. Drop a couple of drops of blue or green food coloring.

* Close the lid tightly so that water does not spill out.

* Have the children turn the bottle over and watch the jellyfish swim in it.

8. Chemical experiments: magic crystals in a glass

You will need:

- glass cup or bowl

- plastic bowl

- 1 cup Epsom salt (magnesium sulfate) - used in bath salts

- 1 cup hot water

- food coloring.

1. Pour Epsom salt into a bowl and add hot water. You can add a couple of drops of food coloring to the bowl.

2. Stir the contents of the bowl for 1-2 minutes. Most of the salt granules should dissolve.

3. Pour the solution into a glass or glass and place it in the freezer for 10-15 minutes. Don't worry, the solution isn't hot enough to crack the glass.
