What experiments can be done with colored water. Educational experiences with water for curious children. First you need to add sugar to the glasses according to this scheme.
Begins at a very early age. Already at 4 months, the baby can distinguish colors well, and a little later, by the age of one, we begin to acquaint the child with the name of the primary colors.
Today I want to offer you several experiments that will help you to visually show your child such concepts as color composition, color mixing, natural dyes. In addition, these simple experiments will allow the baby to get in touch with the natural world, helping him to understand how plants drink water and how a medicine is made from plants. So, today we will talk about the following experiments for children with color:
- extraction of color from leaves
- mixing colors
- blue Rose
- color chromatography
- drawing on fabric
Extraction of color from leaves
Does your child already know that paints are bought in the store? Invite him to make his own paint from the leaves. For this we need green leaves, a bowl, rubbing alcohol and a pot of water. We took grape leaves and pharmacy alcohol. Pour the leaves with alcohol so that they are covered by about 2-3 cm, and put them in a water bath.
As the contents of the bowl heat up, the alcohol will turn green and the leaves will turn pale. Why it happens? The fact is that alcohol is an excellent extractor, that is, it can extract (pull) various substances from plants. Today our goal was green, which is carried in the plant by chlorophyll. Various medicinal tinctures are made according to the same principle. Then the purpose of the extraction is the beneficial substances contained in the plants - them and the roots.
It should be noted that during the experiment, one bottle of alcohol was not enough for complete discoloration of the leaves, since alcohol evaporates very quickly when heated. But at the same time, we got a concentrated emerald color, which we were able to paint with. If you use petals and leaves painted in other colors as raw materials, you will get a whole range of paints for creativity, etc.
Color mixing
Mixing colors in children always arouses genuine interest. But in the absence of a developed abstract imagination, it is difficult for them to do this in their minds and remember the result of their creativity. The experience below will allow children to see both the original (primary) colors and the result of mixing them in real time.
So, we take six plastic transparent glasses and fill three of them with water. Add dyes to the water. We used 3 primary colors of food coloring - red, blue, yellow. We put the glasses in a circle, alternating between empty and full glasses. Now we cut off 6 pieces of bandage equal to two lengths of the glass (so that they get from one bottom to the other). We lay out the bandages, as shown in the photo, and wait. 
You and your child will see that the tinted water began to rise through the bandages and flow into empty glasses. Why? The bandage is made of cotton fabric, the basis of which is a plant - cotton. As in every plant, it contains capillary tubules that conduct water. Through them, water flows from one glass to another, which is called the capillary effect.
Do you want to play with your child easily and with pleasure?
Important! It is better to fill the glasses with paint completely, as the water will overflow until the level is set in the glasses. It is better to twist the bandages into bundles, as in the last photo - this way it will be easier for water to get from one glass to another.
Blue Rose
This experience is a logical continuation of the previous one, but it will take you 3 days in time. We take, in our case, it is a rose. We put it in water dyed with food coloring, making a long oblique cut or cutting the stem into several parts. This will allow the paint to reach the petals faster. It is better to carry out these manipulations in warm water so that air does not enter the tubules and they are not blocked. 
We chose a blue color, and by the evening the rose began to turn blue, starting at the edge of the outer petals.
How to change the color of flowers using ether and ammonia, you will see in this video:
Color chromatography
We have already learned how to mix colors. Now let's try to decompose the colors into components. For this we need filter paper and felt-tip pens. In the absence of special paper, a paper towel or napkin will come in handy. Draw a strip with a felt-tip pen two centimeters from the edge. We lower the edge of the paper 1 cm into the water so that the water does not directly wet the mark from the felt-tip pen. We take out the paper and hang it vertically.
Water, rising over the paper, carries away the paint. But different particles of paint move at different speeds, and therefore visually the paint is decomposed into its constituent components. Thus, we can find out with which colors a particular shade is obtained. This method is called chromatography and is widely used in industry and scientific laboratories to break down substances into their constituents. 
We used ordinary paper napkins and felt-tip pens: blue, purple, orange and pink (I later duplicated the colors on top to make it clear which color we were researching). It turned out to see the composition of all colors, except for pink. The unexpected thing was that blue is not the main one and is obtained by mixing with green, and pink is its own color. But the color chromatography options of the felt-tip pen will vary depending on the manufacturer. Share in the comments what happened with you?
Drawing on fabric
Using our knowledge of the capillary effect, let's try to make a drawing on the fabric using felt-tip pens and alcohol. Pull a thick cotton cloth over the glass (gauze will not work, since the threads are too far from each other), put dots in the center in a circle with a felt-tip pen and drip a drop of alcohol into the center with a pipette. The drop begins to spread from the center to the periphery in all directions, carrying the paint along with it. As a result, we get beautiful flowers on the fabric.
We didn’t find dense cotton fabric, so we used knitted fabric. The photo shows that we experimented with the density of dots, and you can try to put dots in two or three rows.
We hope that the color experiments for children will help you to plunge into the bright world of colors and make your activities with your baby interesting and exciting.

There are very simple experiences that children remember for a lifetime. The guys may not fully understand why this is all happening, but when time passes and they find themselves in a physics or chemistry lesson, a completely illustrative example will surely pop up in their memory.
site collected 7 interesting experiments that will be remembered by children. Everything you need for these experiments is at your fingertips.
Refractory ball
It will take: 2 balls, candle, matches, water.
An experience: Inflate the balloon and hold it over a lighted candle to demonstrate to the children that the balloon will burst from the fire. Then pour plain tap water into the second ball, tie it and bring it back to the candle. 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.
An experience: Pour half of the water into a plastic bag. With a pencil we pierce the bag through in the place where it is filled with water.
Explanation: If you pierce a plastic bag and then pour water into it, it will pour out through the holes. But if you first fill the bag with water halfway and then pierce it with a sharp object so that the object remains stuck in the bag, then water will hardly flow out through these holes. This is due to the fact that when polyethylene breaks down, its molecules are attracted closer to each other. In our case, the polyethylene is tightened around the pencils.
Unbreakable ball
You will need: a balloon, a wooden skewer and some dishwashing liquid.
An experience: Lubricate the top and bottom with the product and pierce the ball starting from the bottom.
Explanation: The secret to this trick is simple. In order to preserve the ball, you need to pierce it at the points of least tension, which are located at the bottom and top of the ball.
Cauliflower
It will take: 4 glasses of water, food coloring, cabbage leaves or white flowers.
An experience: Add food coloring of any color to each glass and place one leaf or flower in the water. Leave them overnight. In the morning you will see that they are colored in different colors.
Explanation: Plants absorb water and thus nourish their flowers and leaves. This is 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 eat. Sucking in the colored water, they change their color.
Floating egg
It will take: 2 eggs, 2 glasses of water, salt.
An experience: Place the egg gently in a glass of plain clean water. As expected, it will sink to the bottom (if not, the egg might be rotten and shouldn't be returned to the refrigerator). Pour warm water into the second glass and stir 4-5 tablespoons of salt in it. For the purity of the experiment, you can wait until the water cools down. Then dip the second egg into the water. It will float near the surface.
Explanation: It's all about density. The average density of the egg is much higher than that of plain water, so the egg sinks downward. And the density of the brine is higher, and therefore the egg rises up.
Crystal lollipops
In the experiments presented below, any child can get acquainted with the interesting properties of such an interesting transparent liquid as water. These are simple experiments with water for preschoolers, but when showing them to children, do not forget about basic safety rules.
Experiment with matches
For the first experience with water for preschoolers, you will need a glass beaker, watercolors, a deep plate, and plasticine. An experiment using water will clearly show how the air pressure changes during combustion.
- You need to pour water into a glass, add any color from paints to it with a brush and stir it, this is necessary for the clarity of the experiment.
- Next, in an empty plate on the bottom, put a piece of plasticine, into which you insert matches - two pieces.
- Pour colored water from a glass into a plate.
- Under the supervision of adults, these matches should be set on fire and covered with an empty dry glass.
As a result of a simple experiment, matches go out, and colored water begins to rise up. This is because during combustion, the air pressure in the glass becomes less than outside.
Experiments with water of different temperatures
For the next experiment, you will need four glass glasses and paints. This water experiment for preschoolers shows the properties of water at different temperatures.
- You need to pour cold water into two glasses, warm water into the other two.
- You can add yellow to cold water, and black to warm water.
- Put one of the glasses with yellow cold water on a plate. And cover a glass of warm water with a plastic card and turn it upside down and in this form put it on a glass of cool water, that is, glasses with different water will be mirrored, with a plastic card between them.
- Then you need to very carefully pull out the card, while you need to make sure that the glasses do not move, hold them in their original position.
Here you can see that cold and hot water did not mix, this is because heat tends upward, and cold - downward.
There are still two glasses left, you can try to carry out this experiment on the contrary - put hot water down and cold water up. The water will then mix.
Dancing droplet
Our third preschool experiment involves using a pot and water.
If you put cold water on the bottom of a pot, nothing happens. But if the pot is heated on the stove under the supervision of an adult, the water droplets in the pot will perform merry dances.
Rainbow water
To make experiments with water for preschoolers more entertaining, it is better to paint the water in different colors using ordinary watercolors. For the next experiment, you need paints, granulated sugar, a glass of glass, water, a syringe, four small glass cups.
- You do not need to pour sugar into the first glass, half a teaspoon of sugar should be thrown into the second, a full spoonful of sugar in the third, and one and a half in the fourth.
- Now you need to add water to each glass, stir the sugar.
- For the first, take the red color and stir, for the second - green, add black to the third, and yellow to the fourth.
- Then you need to take a syringe and draw water from the first glass of red water without sugar. Pour the contents of the syringe into an empty prepared glass.
- Next, using a syringe, green water is drawn from the second glass, in which half a teaspoon of sugar is dissolved, the syringe must be lowered to the bottom of the glass with red typed water and slowly released the water with green paint.
- Now the same procedure should be carried out with the third glass, where the water is black with sugar in the amount of one spoon. You need to release it from the syringe by analogy with the previous step.
- And the fourth glass remained. All the same - water is drawn from it with a syringe, released to the bottom of the glass.
At the end of the experiment, you can see how "rainbow water" was obtained in the glass, all the colored layers of water did not mix, but were located one after the other, having clear boundaries. The more sugar is added, the greater the density of the water, which explains the lack of mixing. The more colors you use, the more colorful and visual the experience will be.
Solid liquid
To conduct the experiment, you will need a deep plate, water, liquid dye, starch.
- Pour starch (half a glass) into a plate and pour over water, add a little liquid paint, you can take food coloring.
- The resulting mass must be mixed well.
You will get an unusual liquid that easily pours, but if you hit such a liquid sharply, it will turn out to be solid.
Galileo STS - Non-Newtonian Liquid
Colorful lamp
Such spectacular experiences with preschool children are especially popular.
- Mix half a glass of sunflower oil with the same amount of water, add the dye.
- Take an aspirin tablet, throw it on the bottom of the container with the resulting mixture.
The aspirin begins to fizzle and mix the oil and water, and the paint droplets begin to dissolve. A very beautiful sight. For illumination, you can direct the beam of the flashlight.
Bringing to a boil
Take a glass of water and place it in the microwave until the water practically boils.
Attention! It should be removed only with an oven mitt, the glass will be hot.
Immediately place a pencil in a glass of boiling water, and you will see how, in an amazing way, the water boils to the formation of air bubbles upon contact with a third-party object. In addition to a pencil, you can put anything in the water: it can be a toy dinosaur or an ordinary spoon.
The fact is that steam bubbles cannot form in a microwave oven in a transparent glass of water, there is simply no place for them. Why? The temperature of the glass container, in this case, the glass, which is transparent for microwave microwaves, is much lower than the temperature of the water in it. Therefore, if there are no bubbles in the water, then it can neither cool nor heat.
But if you put any object there, it heats up to the temperature of the water, while allowing it to cool down, due to the thermal conductivity of the water, so boiling begins. Steam is released.
Carrying out such experiments for preschoolers should be very careful.
Ice formation
In this experiment, you will need a 0.5 L plastic bottle with a cap filled with distilled still water.
- The bottle should be placed in a freezer at -25 degrees for 2 hours.
- After that, take out the bottle and hit it upside down on the table - the water will begin to freeze right before your eyes.
The whole process can be explained by the fact that there are no crystallization centers in distilled water, moreover, it is at rest in the freezer. But as soon as it is shaken sharply, air bubbles appear in the water, which provoke the crystallization process, and the water begins to solidify, turn into ice.
We offer you to carry out such simple, but interesting experiments and experiments for preschoolers at home or in kindergarten. We are sure that they will interest not only children, but also adults.
Interesting experiments with water! Experiments for kids!
Reading 12 min.
Parents of little fidgets can surprise them with experiments that can be done at home. Lightweight, but at the same time amazing and delightful, they can not only diversify the child's leisure time, but also allow you to look at familiar things with completely different eyes. And discover their properties, functions, purpose.
Young naturalists
Experiments at home that are great for children under 10 are the best way to help your child gain practical experience that will be useful in the future.
Experiment Safety
In order for the conduct of cognitive experiments not to be overshadowed by troubles and injuries, it is enough to remember a few simple but important rules.
Safety comes first - Before starting to work with chemicals, the work surface must be protected by covering it with film or paper. This will save parents from unnecessary cleaning and will preserve the appearance and functionality of the furniture.
- In the process of work, you do not need to get too close to the reagents, bending over them. Especially if the plans include chemical experiments for young children, in which unsafe substances are involved. The measure will protect the mucous membranes of the mouth and eyes from irritation and burns.
- If possible, you need to use protective equipment: gloves, goggles. They should be suitable for the child in size and not interfere with him during the experiment.
Simple experiments for the little ones
Developmental experiments and experiments for the smallest children (or for children under 10 years old) are usually simple and do not require any special skills or rare or expensive equipment from their parents. But the joy of discovery and miracle, which is so easy to do with your own hands, will remain with him for a long time.
For example, children will be indescribably delighted with the real seven-color rainbow, which they can call themselves with the help of an ordinary mirror, a container of water and a sheet of white paper.
Experience with a rainbow in a bottle To begin with, a mirror is placed on the bottom of a small basin or bath. Then, it fills with water; and the light of the lantern is directed to the mirror. After the light is reflected and passes through the water, it decomposes into its constituent colors, becoming the very rainbow that can be seen on a sheet of white paper.
Another very simple and beautiful experiment can be carried out using ordinary water, wire and salt.
To begin the experiment, you need to prepare a supersaturated salt solution. It is quite simple to calculate the required concentration of a substance: with the required amount of salt in water, it stops dissolving when the next portion is added. It is very good to use warm distilled water for this purpose. To make the experiment more successful, the finished solution can also be poured into another container - this will remove dirt and make it cleaner.
Experiment "Salt on Wire" When everything is ready, a small piece of copper wire with a loop at the end is dipped into the solution. The container itself is removed to a warm place and left there for a certain time. As the solution begins to cool, the solubility of the salt will decrease and it will begin to settle on the wire in the form of beautiful crystals. You can see the first results in a few days. By the way, it is possible to use in the experiment not only the usual, straight wire: by twisting fancy figurines from it, you can grow crystals of various sizes and shapes. By the way, this experiment will give the child a great idea of New Year's toys in the form of real ice snowflakes - you just need to find a flexible wire and form a beautiful symmetrical snowfield from it.
Invisible ink can also make an indelible impression on the child. It is very simple to prepare them: you just need to take a cup of water, matches, cotton wool, half a lemon. And a sheet on which you can write text.
Invisible ink can be purchased off-the-shelf First, mix equal amounts of lemon juice and water in a cup. Then, a little cotton is wound around a toothpick or thin match. The resulting "pencil" is dipped into the mixture in the resulting liquid; then they can write any text on a sheet of paper.
Although at first the words on paper will be completely invisible, it will be very easy to manifest them. To do this, a sheet with already dried ink must be brought to the lamp. Written words will immediately appear on a heated sheet of paper.
Which kid doesn't like balloons?
It turns out that even an ordinary balloon can be inflated in a very original way. To do this, dissolve one spoonful of baking soda in a bottle of water. And in another cup the juice of one lemon and three tablespoons of vinegar are mixed. After that, the contents of the cup are introduced into the bottle (for convenience, you can use a small funnel). The ball must be put on the neck of the bottle as quickly as possible until the chemical reaction is over. During this time, carbon dioxide can quickly inflate the balloon under pressure. To prevent the ball from jumping off the neck of the bottle, it can be secured with electrical tape or tape.
Inflate the balloon experience Colored milk looks very interesting and unusual, the colors of which will move, fantastically mixing with each other. For this experiment, pour some whole milk into a bowl and add a few drops of food coloring to it. Separate areas of the liquid will be colored in different colors, but the spots will remain stationary. How do you set them in motion? Very simple. It is enough to take a small cotton swab and, after dipping it in the detergent, bring it to the surface of colored milk. Reacting with molecules of milk fat, the molecules of the detergent will make it move.
Experience "Drawings in milk" Important! Skim milk will not work for this experiment. Only one piece can be used!
Surely all children have had a chance to watch funny air bubbles in mineral or sweet water at home and on the street. But are they strong enough to lift a grain of corn or raisins to the surface? It turns out, yes! To check this, it is enough to pour any soda water into the bottle, and then throw some corn or raisins into it. The child will be convinced for himself how easy it is under the influence of air bubbles and corn, and the raisins will begin to rise up, and then, having reached the surface of the liquid, they will again go down.
Experiments for Older Children
Older children (from 10 years old) can be offered more complex chemical experiments requiring more components. These experiments for older children are a little more difficult, but children can already take part in them.
To comply with safety regulations, children under 10 years old must conduct experiments under the strict supervision of adults, mainly in the role of a spectator. Children over 10 years old can take a more active part in the experiments.
An example of such an experiment would be the creation of a lava lamp. Surely many children dream of such a miracle. But, it is much more pleasant to make it yourself, using simple components for this, which are likely to be found in every home.
Experiment "Lava lamp" The base of the lava lamp will be a small jar or the most common glass. In addition, for the experiment, you will need vegetable oil, water, salt and a little food coloring.
The jar, or other container used as the base of the lamp, is filled with water two-thirds and one-third with oil. Since oil is much lighter in weight than water, it will remain on its surface without mixing with it. Then, a little food coloring is added to the jar - this will give the lava lamp color and make the experiment more beautiful and spectacular. And after that, a teaspoon of salt is placed in the resulting mixture. For what? The salt causes the oil to sink to the bottom in the form of bubbles, and then, dissolving, pushes them up.
The next chemistry experiment will help make a school subject like geography exciting and interesting.
Making a volcano with your own hands After all, it is much more interesting to study volcanoes when there is not just a dry book text nearby, but a whole model! Especially if you make it easy at home with your own hands, using the available tools at hand: sand, food coloring, soda, vinegar and a bottle are perfect.
To begin with, a bottle is installed on a tray - it will become the basis of the future volcano. Around it you need to mold a small cone of sand, clay or plasticine - so the mountain will acquire a more complete and believable appearance. Now you need to cause a volcanic eruption: a little warm water is poured into a bottle, then a little soda and food coloring (red or orange). The finishing touch is a quarter cup of vinegar. Reacted with baking soda, the vinegar will actively push out the contents of the bottle. This explains the interesting effect of the eruption, which can be observed with the child.
A volcano can be made from toothpaste Can paper burn without burning?
It turns out, yes. And the experiment with fireproof money will easily prove it. To do this, a ten-ruble banknote is immersed in a 50% alcohol solution (water is mixed with alcohol in a 1 to 1 ratio, a pinch of salt is added to it). After the bill is properly soaked, excess liquid is removed from it, and the bill itself is set on fire. Having flared up, it will start to burn, but at the same time it will not burn at all. The explanation of this experience is quite simple. The temperature at which alcohol burns is not high enough to evaporate the water. Thanks to this, even after the substance has completely burned out, the money will remain slightly damp, but absolutely intact.
Ice experiments are always successful Young nature lovers can be encouraged to germinate seeds at home without using soil. How it's done?
A little cotton wool is placed in the eggshell; it is actively moistened with water, and then some seeds (for example, alfalfa) are put into it. In just a few days, the first shoots will be noticed. Thus, soil is not always needed for seed germination - only water is enough.
And the next experiment, which is easy to conduct at home for children, will certainly appeal to girls. After all, which of them does not like flowers?
A painted flower can be presented to mom Especially the most unusual, bright colors! Thanks to a simple experience, right in front of amazed children, simple and familiar flowers can turn into the most unexpected color. Moreover, it is extremely simple to do this: it is enough to put a cut flower in water with food coloring added to it. Climbing the stem to the petals, chemical dyes will dye them in the colors you want. To better absorb water, it is better to cut the cut diagonally - this way it will have the maximum area. In order for the color to appear brighter, it is advisable to use light or white flowers. An even more interesting and fantastic effect will be obtained if, before the start of the experiment, the stem is split into several parts and each of them is immersed in its own glass with colored water.
The petals will be colored in all colors at once in the most unexpected and bizarre way. That we will undoubtedly make an indelible impression on the child!
Experiment "Colored foam" Everyone knows that under the influence of gravity, water can only flow down. But, is it possible to make it go up the napkin? For this experiment, an ordinary glass is filled with water by about a third. The napkin is folded several times so that you get a narrow rectangle. After that, the napkin unfolds again; stepping back a little from the bottom edge on it, you need to draw a line of colored dots of a sufficiently large diameter. The napkin is immersed in water so that its painted part is about one and a half centimeters in it. Having touched the napkin, the water will gradually rise upward, staining it with multi-colored stripes. This unusual effect is due to the fact that, having a porous structure, the fibers of the napkin easily allow water to pass upwards. 
The gelatinous water is immiscible
Gelatin dissolves in a quarter glass of water; it should swell and increase in volume. Then, the substance is dissolved in a water bath and brought to about 50 degrees. the resulting liquid must be distributed in a thin layer over a plastic bag. With the help of cookie cutters, figures of various shapes are cut out of gelatin. After that, they need to be laid on a blotter or napkin, and then breathe on them. The warm breath will cause the gelatin to expand, making the figurines curl on one side.
Experiments carried out at home with children are very easy to diversify.
Gelatin figures from molds In winter, you can try to slightly modify the experiment by taking out the gelatinous figures to the balcony or leaving them in the freezer for a while. When gelatin hardens under the influence of cold, patterns of ice crystals will clearly appear on it.
Conclusion
Description of other experiments Delight and a sea of positive emotions - this is what the experimenting for curious children, carried out together with adults, will give. And parents will allow themselves to share with young researchers the joy of first discoveries. After all, no matter how old a person is, the opportunity to return to childhood at least for a short time is truly priceless.
The world around us is huge and diverse. The more interest and curiosity a child has in him, the more opportunities he has for development. People, animals, plants, technology, natural phenomena, the laws of physics and chemistry, geography - all this becomes the subject of close study and observation. Of course, you can give children ready-made answers, build templates into their perception of the world. Or you can give them the opportunity to test everything on their own experience. Let's experiment?
CHEMICAL WITH GELATIN... Dissolve the gelatin (1/4 cup cold water - 10 g of dry gelatin). To dissolve it better, place the glass in hot water. Then pour a thin layer of gelatin onto a plastic bag and let it stand in the air. When the mass hardens, cut out the shape of a fish from it. Place the fish on a blotter and breathe on it. A miracle will happen: the "fish" will come to life and begin to bend. Why is this happening? When you breathe, the surface of the “fish” heats up and the mass expands, while the lower part of it remains cold, and the “fish” curls, as it were.
FINGERPRINTS... The Sherlock Holmes game continues. Now you need to take your fingerprints. To do this, you need to prepare a mixture of soot and talcum powder. Ask the child to breathe on the finger and place it firmly against the paper. Sprinkle the mixture over the area, shake it off, and you will see a clear fingerprint. Why is this happening? Tell your child that there is some fat on the surface of our body (including fingers), and if we touch something, this fat is imprinted on objects. The magic powder just adhered to the grease prints, and the black color of the mixture made it visible.
CLOUD IN BANK... Pour hot water into a three-liter jar (level - 3-4 cm), cover the jar with a baking sheet on top, put pieces of ice on it. Warm air inside the jar will begin to cool, condense and rise up in the form of a cloud. In this simple experimental way, you can explain to your child how clouds are formed. And also - why is it raining. Drops in clouds are aliens from Earth. In the form of heated steam, they rise up, there they become cold, they reach out to each other, become heavy, large and ... again return to their homeland.
CAN THE FOIL DANCE? There is likely to be a piece of foil in your home. Cut it into thin strips. Then take a comb and comb your hair, then bring the comb to the strips - and they will begin to move. It is difficult to explain anything to children about how electrical charges interact. You can tell the children that particles fly in the air that cannot live without each other, they are attracted to each other, although they are different in character, like "+" and "-".
HOW TO MAKE A MAGNIFYING GLASS? For this experiment, you will need an empty three-liter jar and a "guinea pig": for example, a spider, a fly, an ant. I would like to see how the little creature moves, cleans its paws, raises its wings, etc. To do this, put the insect in a jar, tighten the neck of the jar with transparent cling film, just do it so that there is a small depression in the film. Pour water into this depression, which will be the magnifying glass. Do not forget to release the animals after the experiment. Teach your child to treat all living things with love. It doesn't matter who it is: a cat or a little ant.
You can go the other way. Tape a small object to the outside of the jar. Pour water into a jar and look at the object through the water.
Secret letter
Play detectives with your child who have found important clues - mysterious messages. Write each other encrypted letters. This can be done in several ways:
Option 1. Take a sheet of white paper, dip a thin brush in milk and write a message. What is written must definitely dry out! Then hold the sheet over steam or dry it with an iron.
Option 2. Squeeze out the lemon juice. This will be your sympathetic ink. Take a sheet of white paper, dip a brush in juice and write your code. To read it, you need to lightly smear the lines with iodine.
KITCHEN EXPERIMENTS
Your kitchen is a great place to experiment. Not only culinary. Here you can check how the laws of physics work, how different substances interact with each other. Finally, you can do a few tricks and surprise your neighbors and acquaintances. Or just make a treat with your own hands.
Two oranges
Dip an orange in a bowl of water and see how well it can swim. Then peel the same orange and put it in water: it will immediately sink to the bottom. Why? Tell your child that there are a lot of air bubbles in the orange peel, it is held by them, like on an "inflatable pillow."
DIFFERENT "CHARACTER" IN EGGS... Take two eggs: raw and boiled. Roll the eggs (everyone knows this method). Why does one rotate fast and well? And the other does not obey and does not want to rotate? It is difficult to tell the child about the center of gravity (not all adults can understand this). Try to explain that in a boiled egg (it is hard) there is a constant center of gravity (like a point that stands still), and in a raw egg, liquid white and yolk are like a rotation brake, because the "point" does not stand still, but moves.
"WATER" EGG. Take two liter cans of water. Add 2 tbsp. To one jar. tablespoons of salt and stir well. Submerge one egg in a jar of fresh water and the other in salted water. Why does an egg sink in fresh water, and rise to the surface in salty water? The question will be obvious. Try to make the answer convincing, if not obvious.
