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

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

Fireproof ball

Will need: 2 balls, candle, matches, water.

Experience: Inflate a balloon and hold it over a lit candle to demonstrate to children that the fire will make the balloon burst. Then pour plain tap water into the second ball, tie it 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 ball absorbs the heat generated by the candle. Therefore, the ball itself will not burn and, therefore, will not burst.

Pencils

You will need: plastic bag, pencils, water.

Experience: Fill the plastic bag halfway with water. Use a pencil to pierce the bag right through 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 into 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 tightened around the pencils.

Unbreakable balloon

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

Experience: Coat 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 preserve 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

Will need: 4 cups of water, food coloring, cabbage leaves or white flowers.

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

Explanation: Plants absorb water and thereby nourish their flowers and leaves. This happens due to the capillary effect, in which 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 color.

floating egg

Will need: 2 eggs, 2 glasses of water, salt.

Experience: Carefully 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 place the second egg in 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 salt solution is higher, and therefore the egg rises up.

Crystal lollipops

Will need: 2 cups of water, 5 cups of sugar, wooden sticks for mini kebabs, thick paper, transparent glasses, saucepan, food coloring.

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

Leave the sticks to dry overnight. In the morning, dissolve 5 cups of sugar in 2 glasses of water over a fire. You can leave the syrup to cool for 15 minutes, but it should not cool too much, otherwise the crystals will not grow. Then pour it into jars and add different food colorings. Place the prepared sticks in 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 seeded with sugar grains.

Lighted match

Will be needed: 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 because it does not prevent light from passing through it.

Home experiments for 4-year-old children require imagination and knowledge of the simple laws of chemistry and physics. “If these sciences were not taught very well at school, you will have to make up for lost time,” many parents will think. This is not so, experiments can be very simple, not requiring special knowledge, skills and reagents, but at the same time explaining the fundamental laws of nature.

Experiments for children at home will help explain the properties of substances and the laws of their interaction using a practical example, and awaken interest in independent exploration of the world around them. Interesting physical experiments will teach children to be observant and help them think logically, establishing patterns between ongoing events and their consequences. Perhaps the kids will not become great chemists, physicists or mathematicians, but they will forever retain warm memories of parental attention in their souls.

From this article you will learn

Unfamiliar paper

Kids like to make appliqués out of paper and draw pictures. Some 4-year-old children learn the art of origami with their parents. Everyone knows that paper is soft or thick, white or colored. What can a regular white sheet of paper do if you experiment with it?

An animated paper flower

Cut out a star from a sheet of paper. Its rays bend inward in the form of a flower. Fill a cup with water and lower the star onto the surface of the water. After some time, the paper flower, as if alive, will begin to open. The water will wet the cellulose fibers that make up the paper and spread them out.

Strong bridge

This paper experiment will be interesting for children 3 years old. Ask the kids how to place an apple in the middle of a thin sheet of paper between two glasses so that it does not fall. How can you make a paper bridge strong enough to support the weight of an apple? We fold a sheet of paper into an accordion shape and place it on the supports. Now it can support the weight of the apple. This can be explained by the fact that the shape of the structure has changed, which made the paper strong enough. The properties of materials that become stronger depending on their shape are the basis for the designs of many architectural creations, for example, the Eiffel Tower.

An animated snake

Scientific evidence of the upward movement of warm air can be provided using simple experiment. A snake is cut out of paper by cutting a circle in a spiral. You can revive a paper snake very simply. A small hole is made in her head and suspended by a thread above a heat source (battery, heater, burning candle). The snake will begin to rotate quickly. The reason for this phenomenon is the upward warm flow of air, which unwinds the paper snake. This is exactly how you can make paper birds or butterflies, beautiful and colorful, by hanging them under the ceiling in your apartment. They will rotate from the movement of air, as if flying.

Who is stronger

This fun experiment will help you determine which paper shape is stronger. For the experiment you will need three sheets of office paper, glue and several thin books. A cylindrical column is glued from one sheet of paper, a triangular column from another, and a rectangular column from the third. They place the “columns” vertically and test them for strength, carefully placing books on top. As a result of the experiment, it turns out that the triangular column is the weakest, and the cylindrical column is the strongest - it will withstand the greatest weight. It is not for nothing that columns in churches and buildings are made in a cylindrical shape; the load on them is distributed evenly over the entire area.

Amazing salt

Regular salt is found in every home today; no meal can be prepared without it. You can try making beautiful children's crafts from this affordable product. All you need is salt, water, wire and a little patience.

Salt has interesting properties. It can attract water to itself, dissolving in it, thereby increasing the density of the solution. But in a supersaturated solution, the salt again turns into crystals.

To conduct an experiment with salt, bend a beautiful symmetrical snowflake or other figure from a wire. Dissolve salt in a jar of warm water until it stops dissolving. Dip a bent wire into a jar and place it in the shade for several days. As a result, the wire will become overgrown with salt crystals, and will look like a beautiful ice snowflake that will not melt.

Water and ice

Water exists in three states of aggregation: steam, liquid and ice. The purpose of this experiment is to introduce children to the properties of water and ice and compare them.

Pour water into 4 ice trays and place them in the freezer. To make it more interesting, you can tint the water with different dyes before freezing. Pour cold water into a cup and throw two ice cubes into it. Simple ice boats or icebergs will float on the surface of the water. This experiment will prove that ice is lighter than water.

While the boats are floating, the remaining ice cubes are sprinkled with salt. They'll see what happens. After a short time, before the indoor float in the cup has time to sink (if the water is quite cold), the cubes sprinkled with salt will begin to crumble. This is explained by the fact that the freezing point of salt water is lower than normal water.

Fire that doesn't burn

In ancient times, when Egypt was a powerful country, Moses fled from the wrath of Pharaoh and tended flocks in the desert. One day he saw a strange bush that was burning and did not burn. It was a special fire. Can objects that are engulfed in ordinary flame remain safe and sound? Yes, this is possible, this can be proven through experience.

For the experiment you will need a sheet of paper or a banknote. A tablespoon of alcohol and two tablespoons of water. The paper is moistened with water so that the water is absorbed into it, alcohol is poured on top and set on fire. Fire appears. This is burning alcohol. When the fire goes out, the paper will remain intact. The experimental result can be explained very simply - the combustion temperature of alcohol, as a rule, is not enough to evaporate the moisture with which the paper is impregnated.

Natural indicators

If your child wants to feel like a real chemist, you can make special paper for him that will change color depending on the acidity of the environment.

The natural indicator is prepared from the juice of red cabbage, which contains anthocyanin. This substance changes color depending on what liquid it comes into contact with. In an acidic solution, paper soaked in anthocyanin will turn yellow, in a neutral solution it will turn green, and in an alkaline solution it will turn blue.

To prepare a natural indicator, take filter paper, a head of red cabbage, cheesecloth and scissors. Chop the cabbage thinly and squeeze the juice through cheesecloth, squeezing it with your hands. Soak a sheet of paper in juice and dry. Then cut the made indicator into strips. The child can dip a piece of paper into four different liquids: milk, juice, tea or soap solution, and watch how the color of the indicator changes.

Electrification by friction

In ancient times, people noticed the special ability of amber to attract light objects if rubbed with a woolen cloth. They did not yet have knowledge about electricity, so they explained this property by the spirit living in the stone. It is from the Greek name for amber - electron - that the word electricity comes.

It’s not just amber that has such amazing properties. You can conduct a simple experiment to see how a glass rod or plastic comb attracts small pieces of paper. To do this, rub the glass with silk and the plastic with wool. They will begin to attract small pieces of paper that will stick to them. Over time, this ability of items will disappear.

You can discuss with children that this phenomenon occurs due to electrification by friction. If fabric rubs quickly against an object, sparks may appear. Lightning in the sky and thunder are also a consequence of friction of air currents and the occurrence of electrical discharges in the atmosphere.

Solutions of different densities - interesting details

You can get a multi-colored rainbow in a glass from liquids of different colors by preparing jelly and pouring it layer by layer. But there is a simpler way, although not as tasty.

To carry out the experiment you will need sugar, vegetable oil, plain water and dyes. Concentrated sweet syrup is prepared from sugar, and clean water is colored with dye. Sugar syrup is poured into a glass, then clean water is poured carefully along the wall of the glass so that the liquids do not mix, and vegetable oil is added at the end. The sugar syrup should be cold and the colored water should be warm. All liquids will remain in the glass like a small rainbow, without mixing with each other. The thickest sugar syrup will be at the bottom, the water will be at the top, and the lightest oil will be on top of the water.

Color explosion

Another interesting experiment can be carried out using different densities of vegetable oil and water, creating a color explosion in a jar. For the experiment you will need a jar of water, a few tablespoons of vegetable oil, and food coloring. In a small container, mix several dry food colors with two tablespoons of vegetable oil. Dry grains of dyes do not dissolve in oil. Now the oil is poured into a jar of water. Heavy grains of dye will settle to the bottom, gradually freeing themselves from the oil, which will remain on the surface of the water, forming colored swirls, as if from an explosion.

Home volcano

Useful geographic knowledge may not be so boring for a four-year-old if you provide a visual demonstration of a volcano erupting on an island. To carry out the experiment you will need baking soda, vinegar, 50 ml of water and the same amount of detergent.

A small plastic cup or bottle is placed in the mouth of a volcano, molded from colored plasticine. But first, baking soda is poured into a glass, water tinted red and detergent are poured. When the improvised volcano is ready, a little vinegar is poured into its mouth. A rapid foaming process begins due to the fact that soda and vinegar react. “Lava” formed by red foam begins to pour out of the volcano’s mouth.

Experiments for 4-year-old children, as you have seen, do not require complex reagents. But they are no less fascinating, especially with an interesting story about the reason for what is happening.

Entertaining chemical experiments will prepare children for studying chemistry at school. Most of the experiments carried out at home are not dangerous, educational, and effective. Some experiments are provided with a written description, which will help explain to the child the essence of the processes taking place and awaken interest in chemical science.

When conducting chemical experiments at home, the following safety rules must be observed:

Simple experiments for little ones

Chemical experiments for young children, carried out at home, do not require any special substances.

Colored bubbles

For one such experiment you will need:

fruit juice;
sunflower oil;
2 effervescent tablets;
decorative transparent container.

Stages of experience:

You can create bubbles with a stronger shell yourself by mixing water and dishwashing detergent in a 2:1 combination + a little granulated sugar. If you add glycerin instead of sugar, the bubbles will reach very large sizes. Adding food coloring to the soap solution will create colored glowing bubbles.

Night light

You can make a night light at home using simple substances. To do this you will need:

tomato;
syringe;
sulfur heads from matches;
hydrogen peroxide;
bleach.

Sequencing:

Place sulfur in a bowl, add bleach, and leave for a while.
Draw the mixture into a syringe and prick the tomato from all sides.
To start the chemical reaction, hydrogen peroxide must be introduced. This is also done with a syringe in the place where the petiole was located.
When in a dark room, the tomato will emit soft light.

Carefully! You can no longer eat this tomato.

Sizzling balls

You can make your own sizzling balls for children's bathing.

During work, hands must be protected with gloves.

Sequencing:

Floating worms

For the next experiment you will need:

3 jelly worm candies without sugar sprinkles;
soda;
acetic acid;
water;
glass glasses.

Stages of work:

The first glass is half filled with acetic acid.
Pour warm water into the second glass and dilute 60 g of soda.
Place the candies in the solution and leave for 15 minutes.
Remove the candies from the soda solution and place them in a glass with the essence.
The surface of the candy will immediately become covered with bubbles; they will continuously rise to the surface and fall to the bottom of the glass. This happens because the soda first fills the pores of the candy, then, reacting with vinegar, it releases carbon dioxide, which raises the candy to the top.
When they come into contact with air, the bubbles burst, the candy sinks to the bottom and again becomes covered with bubbles and rises.

Experiments for older children

Chemical experiments for children at home can be more complex and interesting.

Volcano

So, any schoolchild can simulate a volcanic eruption at home:

Colored foam

To experience creating colored foam you will need:

Sequencing:

The glasses are placed on a tray, half filled with soda, and dyes are added.
Mix vinegar with detergent and pour into glasses.
Colored foam will come out of each glass. You can pour the vinegar mixture into glasses several times until all the soda is released.

Malachite egg

The experiment of dyeing a chicken egg the color of malachite is lengthy, but interesting:

To do this, remove the contents from the egg: make 2 holes and blow it out.
For weight, a little plasticine is placed into an empty egg.
Dissolve a spoonful of copper sulfate in 0.5 liters of water (it can be purchased at a hardware store).
Dip the egg into the solution; the shell should be completely immersed in the solution.
After a few days, gas bubbles will appear.
After a week, the shell will acquire a light blue-green color.
After a month, the color of the shell will become rich malachite.

Fireworks

Making fireworks with your own hands:

Magnesium shavings are very finely ground.
Sulfur match heads are separated from the wood. You will need 2-3 boxes of matches. Crushed magnesium is mixed with sulfur powder.
Take a metal tube and seal one of the holes tightly with plaster.
Pour a mixture of magnesium and sulfur into the tube. The mixture should not occupy more than half of the tube.
The tube is wrapped several times with foil. A wick is inserted into the free hole.
Such fireworks can only be exploded in deserted places.

Coloring water blue

To color a colorless liquid blue you need:

alcohol solution of iodine;
hydrogen peroxide;
vitamin C tablet;
starch;
glass glasses.

Performing the experiment step by step:

A vitamin C tablet is ground into powder and dissolved in 55 ml of warm water.
Pour 5 ml of the resulting solution into a glass, add 5 ml of iodine and 55 ml of heated water. The iodine should be discolored.
Separately mix 18 ml of hydrogen peroxide, 5 g of starch, 55 ml of water.
The iodine solution is poured back and forth into the starch solution several times.
The colorless liquid will turn dark blue. Iodine loses color when it reacts with vitamin C. Starch turns blue when mixed with iodine.

Simple experiments on the properties of metals

Chemical experiments for children at home can be carried out with metals.

For simple experiments you will need:

To experiment with copper wire, a small piece of metal is twisted into a spiral and heated strongly over a fire. Then immediately lower it into a container with ammonia. The reaction will occur instantly: the metal will begin to hiss, and the black coating formed when exposed to fire will disappear. The copper wire will shine again. It is better to do the experiment several times, then the color of the ammonia will turn blue.

For the next experiment you will need solid iodine, crushed aluminum, and warm water. Iodine is mixed with aluminum in equal parts. Water is added to the mixture. The powder begins to burn, releasing purple smoke.

Another experiment will involve:

chrome-plated paper clip;
galvanized steel nail;
pure steel screw;
acetic acid;
3 test tubes.

Stages of experience:

Metal objects are placed in test tubes, filled with acid, and left for observation. In the first days, hydrogen evolution is observed.
On the 4th day, the acid in test tubes with coated metal objects begins to turn red. In a test tube with a steel screw, the acid turns orange and a precipitate appears.
After 2 weeks in a test tube with a paper clip, the acid turns red, but only in the upper layers. Where the paperclip is located, the acid is colorless. After removing the paper clip, you can see that its appearance has not changed.
The acid in a test tube with a nail is colored with a smooth transition from red to pale yellow. The nail hasn't changed.
In the 3rd test tube, layered coloration of the liquid and sediment are also observed. The screw turned black, the upper microlayers of the metal collapsed.

Conclusion: unprotected iron is susceptible to corrosion.

For the next experiment, you need to prepare a blue solution of copper sulfate (dissolve several crystals in water, stir). Place non-rusty nails in a test tube and fill with solution. After some time, the solution will turn green and the nails will turn copper-colored. This happened because iron displaced copper from the liquid, and the displaced copper settled on metal objects.

To conduct the “Hydrogen Glove” experiment you will need:

Sequencing:

The saline solution and copper sulfate solution are simultaneously poured into the flask. When mixed, a sea-green liquid is obtained.
Make a lump of foil and place it in the hole of the flask. Immediately, hydrogen begins to rapidly evolve.
Put a rubber glove on the neck, it will instantly fill with gas.
When the glove comes into contact with fire, it ruptures and the gas ignites. The liquid in the vessel gradually acquires a dirty gray tint.

The most spectacular chemical experiments for children

Chemical experiments for children at home are very diverse, and some are very impressive.

Colored foam

To make a large amount of colored foam you need:

Bleached green

For the experiment on bleaching greenery you will need:

Sequencing:

Water is poured into 6 glasses, a drop of greenery is added to each.
The 1st glass is set aside for comparison, bleach is added to 2, ammonia to 3, peroxide to 4.
Ammonia instantly discolors the liquid.
Small bubbles appeared in the glass with bleach, and the solution became colorless.
Hydrogen peroxide will discolor the liquid gradually, over about 15 minutes.
Adding vinegar to the solution will make the liquid brighter.
After 30 min. the liquid becomes lighter.
Activated carbon brightens the solution.

Pharaoh snake

Conducting an experiment called “Pharaoh’s Snake” will require:

Stages of experience:

The sand is soaked in alcohol and formed into a cone.
A recess is made at the top.
Mix soda with sugar and pour into the well.
The soaked sand is set on fire.
The mixture will turn into black balls, soda and sugar will begin to decompose.
After burning the alcohol, a snake will appear, consisting of the products of burning sugar.

Pharaoh's snake made from sugar and soda:

Fire without a spark

To create a fire without a spark, you need potassium permanganate, glycerin and paper.

Sequencing:

Place approximately 1.5 g of potassium permanganate powder in the center of a sheet of paper, cover with the free edge of the sheet.
Apply 3 drops of glycerin to the paper in the place where the powder is located.
After 30 seconds, potassium permanganate will begin to hiss, smoke and produce black foam. The exothermic reaction will heat the paper and it will catch fire.

Fireworks

To make small fireworks at home, you need to choose a small fireproof dish with a long handle.

Sequencing:

On a paper sheet you need to pour a crushed tablet of activated carbon, the same amount of potassium permanganate and the same amount of iron filings.
Fold a piece of paper in half to combine the powders (powders should not be mixed with spoons or spatulas; they may ignite).
Carefully pour into a fireproof container and heat over the burner. After a few seconds. the heated mixture will begin to emit sparks.

Chemistry sets for children

Chemical experiments for children at home will help you carry out special sets of substances and tools.

Experiment kit “Vulcan”

Designed for children over 14 years old, it allows you to independently reproduce the eruption of a small volcano.

Equipment:

To conduct the experiment, you first need to make the volcano itself; sand or gypsum is suitable as a material. When the mountain has frozen, a special powder is poured into the depression and set on fire. The substance begins to burn spectacularly, throwing out sparks, and ash appears.

The advantages of such an experiment include a visual representation of flammable substances. Disadvantages: presence of harmful substances, can only be used once.

Price: 440 rub.

Chemistry set

The kit provides for growing crystals at home.

The set includes:

Stages of work:

Pour crystalline powder into a container and mix with 150 ml of boiling water.
Stir until completely dissolved.
The base of the crystal is immersed in the liquid.
Cover with a lid for 60 minutes.
Add a substance to form a crystal into the cooled water and close the lid.
After a day, remove the lid.
Wait until the top of the crystal appears above the water.
The water is drained, the crystal is removed and dried.

The experiment is very interesting for children and is practically safe, but it will take at least 4 days to complete.

Cost of the set: 350 rub.

Set for chemical experiments “Traffic light”

Set includes:

sodium hydroxide;
glucose;
indigo carmine;
2 measuring cups;
gloves.

Sequence of experience:

Glucose (4 tablets) is dissolved in 1 glass using a small amount of boiling water. Add 10 mg sodium hydroxide solution.
A little indigo carmine is dissolved in the 2nd glass.
A solution of glucose and alkali is poured into the resulting blue liquid.
When mixing the solutions, the liquid will turn green (oxygen in the air oxidizes indigo carmine).
Gradually the solution will turn red, then yellow. If the vessel with the yellow solution is shaken, the liquid will turn green again, then red and yellow.

The experiment is spectacular, interesting and safe. The disadvantages include insufficiently detailed instructions.

Set price: 350 rub.

Advantages and disadvantages of home experiments

Experience name	Advantages	Flaws
Pharaoh snake	Availability of materials, entertainment	Not safe
Growing Crystals	Complete security, visibility	The experiment is quite long
Volcano	Clearly demonstrates the interaction of substances	Long preparations for the experiment
Experiment on the interaction of metals with various liquids	Effectiveness, safety	Requires a lot of time to carry out
Home fireworks	Entertainment and availability of substances used	Not safe

Most chemical home experiments, when carried out correctly, do not harm the child’s health, but it is better to carry them out under adult supervision. All the necessary substances can be found in any kitchen.

Experiments will reveal to children the secrets of the interaction of substances and arouse interest in understanding the world.

Video on the topic: chemical experiments for children

Home miracle laboratory: chemical experiments for children:

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

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

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

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

Ice soap bubbles

What do you think will happen if simple bubbles that are tiny in 4 years loves to inflate them, run after them and burst them, inflate them in the cold. Or rather, straight into a snowdrift.

I'll give you a hint:

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

Whatever you choose, I can tell you 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'm complicating the question. Is it possible to repeat the experiment in the summer in order to get a similar option?

Choose answers:

Yes. But you need ice from the refrigerator.

You know, although I really want to tell you everything, this is exactly what I won’t do! Let there be at least one surprise for you too!

Paper vs water

The real one is waiting for us experiment. Is it really possible for paper to defeat 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 good if its edges were a little damp, then the paper would stick. Carefully turn the glass over... The water does not leak!

Let's inflate balloons without breathing?

We have already carried out chemical children's experiments. Remember, the very first room for very little babies 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 and inflatable purposes.

Ingredients:

Soda;
Plastic bottle;
Vinegar;
Ball.

Pour soda into the bottle and fill 1/3 with vinegar. Shake lightly and quickly pull the ball onto the neck. When it is inflated, bandage it and remove it from the bottle.

Such a small experience can show even in kindergarten.

Rain from a cloud

We need:

Jar of water;
Shaving foam;
Food coloring (any color, several colors possible).

We make a cloud of foam. A big and beautiful cloud! Entrust this to the best cloud maker, your child. 5 years. He will definitely make her real!

author of the photo

All that remains is to distribute the dye over the cloud, and... drip-drip! Rain is coming!

Rainbow

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

Deep transparent container with water;
Mirror;
Flashlight;
Paper.

Place a mirror at the bottom of the container. We shine a flashlight on the mirror at a slight angle. All that remains is to catch the Rainbow on paper.

Even easier is to use a disk and a flashlight.

Crystals

There is a similar, but 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 let's keep 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 accumulate 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. The colored oil rises gradually, as if a mysterious volcano is bubbling inside the jar.

Eruption

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

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

A hole in the bag is not a problem

This is what convinces book of scientific experiments for children and adults Dmitry Mokhov "Simple Science". And we can check this statement ourselves! First, fill the bag with water. and then we'll pierce it. But we won’t remove what we pierced with (a pencil, a toothpick or a pin). How much water will we leak? Let's check!

Water that doesn't spill

Only such water still needs to be produced.

Take water, paint and starch (as much as water) and mix. The end result is just plain water. You just can't spill it!

"Slippery" egg

In order for the egg to actually fit into the neck of the bottle, you need to set fire to the piece of paper and throw it into the bottle. Cover the hole with an egg. When the fire goes out, the egg will slip inside.

Snow in summer

This trick is especially interesting to repeat in the warm season. Remove the contents of the diapers and wet them with water. All! The snow is ready! Nowadays such snow is easy to find in children's toys in stores. Ask the seller for artificial snow. And there is no need to ruin diapers.

Moving snakes

To make a moving figure we will need:

Sand;
Alcohol;
Sugar;
Soda;
Fire.

Pour alcohol onto a pile of sand and let it soak. Then pour sugar and baking soda on top and set it on fire! Oh, what a funny this experiment! Children and adults will love what the animated snake gets up to!

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

Battery train

The copper wire, which we twist into an even spiral, will become our tunnel. How? Let's connect its edges, forming a round tunnel. But before that, we “launch” the battery inside, only attaching neodymium magnets to its edges. And consider that you have invented a perpetual motion machine! The locomotive moved on its own.

Candle swing

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

Elephant tooth paste

The elephant needs everything big and a lot. Let's do it! Dissolve potassium permanganate in water. Add liquid soap. The last ingredient, hydrogen peroxide, turns our mixture into a giant elephant paste!

Let's drink a candle

For greater effect, color the water in a bright color. Place 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 it will all be saturated inside, towards the candle.
Oxygen is burned, the pressure inside the glass decreases and

A real chameleon

What will help our chameleon change color? Cunning! Instruct your little one 6 years Decorate a plastic plate in different colors. And cut out the chameleon figure yourself on another plate, similar in shape and size. All that remains is to loosely connect both plates in the middle so that the top one, with the cut out figure, can rotate. Then the color of the animal will always change.

Light up the rainbow

Place Skittles in a circle on a plate. Pour water inside the plate. Just wait a little and we 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 an incense stick and place it in the bottle. Close the lid. When there is continuous smoke in the jar, unscrew the lid and tap on the membrane. Smoke will come out in rings.

Multicolored liquid

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

Egg without shell

Place a raw egg in vinegar for at least a day, some say for a week. And the trick is ready! An egg without a hard shell.
The egg shell contains calcium in abundance. 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.
The egg will also be larger than its original size, as it will absorb some of the vinegar.

Dancing men

It's time to get rowdy! Mix 2 parts starch with one part water. Place a bowl of starchy liquid on the speakers and turn up the bass!

Decorating the ice

We decorate ice figures of different shapes using food paint mixed with water and salt. The salt eats away at the ice and seeps deep, creating interesting passages. Great idea for color therapy.

Launching paper rockets

We empty the tea bags of tea by cutting off the top. Let's set it on fire! Warm air lifts the bag!

Experiments with eggs

Egg with salt

The egg will sink to the bottom if you place it in a glass of plain water, but what happens if you add salt? The result is very interesting and can clearly show interesting facts about density.

You will need:

Salt
Tumbler.

Instructions:

1. Fill half the glass with water.

2. Add a lot of salt to the glass (about 6 tablespoons).

3. We interfere.

4. Carefully lower the egg into the water and watch what happens.

Explanation

Salt water has a higher density than regular tap water. It is the salt that brings the egg to the surface. And if you add fresh water to the existing salt water, the egg will gradually sink to the bottom.

Egg in a bottle

Did you know that a boiled whole egg can easily be placed in a bottle?

You will need:

A bottle with a neck diameter smaller than the diameter of an egg
Hard boiled egg
Matches
Some paper
Vegetable oil.

Instructions:

1. Lubricate the neck of the bottle with vegetable oil.

2. Now set fire to the paper (you can just use a few matches) and immediately throw it into the bottle.

3. Place an egg on the neck.

When the fire goes out, the egg will be inside the bottle.

Explanation

The fire provokes heating of the air in the bottle, which comes out. After the fire goes out, the air in the bottle will begin to cool and compress. Therefore, a low pressure is created in the bottle, and the external pressure forces the egg into the bottle.

Ball experiment

This experiment shows how rubber and orange peel interact with each other.

You will need:

Balloon
Orange.

Instructions:

1. Inflate the balloon.

2. Peel the orange, but do not throw away the orange peel (zest).

3. Squeeze the orange zest over the ball until it pops.

Explanation.

Orange zest contains the substance limonene. It is capable of dissolving rubber, which is what happens to the ball.

Candle experiment

An interesting experiment showing ignition of a candle from a distance.

You will need:

Regular candle
Matches or lighter.

Instructions:

1. Light a candle.

2. After a few seconds, put it out.

3. Now bring the burning flame close to the smoke coming from the candle. The candle will start burning again.

Explanation

The smoke rising from an extinguished candle contains paraffin, which quickly ignites. The burning paraffin vapor reaches the wick, and the candle begins to burn again.

Soda with vinegar

A balloon that inflates itself is a very interesting sight.

You will need:

Bottle
Glass of vinegar
4 teaspoons soda
Balloon.

Instructions:

1. Pour a glass of vinegar into the bottle.

2. Pour baking soda into the ball.

3. We put the ball on the neck of the bottle.

4. Slowly place the ball vertically while pouring the baking soda into the bottle with vinegar.

5. We watch the balloon inflate.

Explanation

If you add baking soda to vinegar, a process called soda slaking occurs. During this process, carbon dioxide is released, which inflates our balloon.

Invisible ink

Play secret agent with your child and create your own invisible ink.

You will need:

Instructions:

1. Squeeze some lemon juice into a bowl and add the same amount of water.

2. Dip a cotton swab into the mixture and write something on white paper.

3. Wait until the juice dries and becomes completely invisible.

4. When you are ready to read the secret message or show it to someone else, heat the paper by holding it close to a light bulb or fire.

Explanation

Lemon juice is an organic substance that oxidizes and turns brown when heated. Diluted lemon juice in water makes it hard to see on paper, and no one will know there is lemon juice until it warms up.

Other substances which work on the same principle:

Orange juice
Milk
Onion juice
Vinegar
Wine.

How to make lava

You will need:

Sunflower oil
Juice or food coloring
Transparent vessel (can be a glass)
Any effervescent tablets.

Instructions:

1. First, pour the juice into a glass so that it fills approximately 70% of the container’s volume.

2. Fill the rest of the glass with sunflower oil.

3. Now wait until the juice separates from the sunflower oil.

4. We throw a tablet into a glass and observe an effect similar to lava. When the tablet dissolves, you can throw another one.

Explanation

Oil separates from water because it has a lower density. Dissolving in the juice, the tablet releases carbon dioxide, which captures parts of the juice and lifts it to the top. The gas leaves the glass completely when it reaches the top, causing the juice particles to fall back down.

The tablet fizzes due to the fact that it contains citric acid and soda (sodium bicarbonate). Both of these ingredients react with water to form sodium citrate and carbon dioxide gas.

Ice experiment

At first glance, you might think that the ice cube on top will eventually melt, which should cause the water to spill, but is this really so?

You will need:

Cup
Ice cubes.

Instructions:

1. Fill the glass with warm water to the very top.

2. Carefully lower the ice cubes.

3. Watch the water level carefully.

As the ice melts, the water level does not change at all.

Explanation

When water freezes to ice, it expands, increasing its volume (which is why even heating pipes can burst in winter). The water from melted ice takes up less space than the ice itself. Therefore, when the ice cube melts, the water level remains approximately the same.

How to make a parachute

find out about air resistance, making a small parachute.

You will need:

Plastic bag or other lightweight material
Scissors
A small load (possibly some kind of figurine).

Instructions:

1. Cut a large square from a plastic bag.

2. Now we cut the edges so that we get an octagon (eight identical sides).

3. Now we tie 8 pieces of thread to each corner.

4. Don't forget to make a small hole in the middle of the parachute.

5. Tie the other ends of the threads to a small weight.

6. We use a chair or find a high point to launch the parachute and check how it flies. Remember that the parachute should fly as slowly as possible.

Explanation

When the parachute is released, the weight pulls it down, but with the help of the lines, the parachute takes up a large area that resists the air, causing the weight to slowly descend. The larger the surface area of the parachute, the more that surface resists falling, and the slower the parachute will descend.

A small hole in the middle of the parachute allows air to flow through it slowly, rather than having the parachute tumble to one side.
