Chemistry experiments for children at home. For simple experiments you will need. For one such experiment you will need

Guys, we put our soul into the site. Thank you for that
that you are discovering this beauty. Thanks for the inspiration and goosebumps.

We have a lot of things stored in our kitchen that we can use most interesting experiments for children. Well, for myself, to be honest, make a couple of discoveries from the “how did I not notice this before” category.

website I chose 9 experiments that will delight children and raise many new questions in them.

1. Lava lamp

Needed: Salt, water, a glass of vegetable oil, some food coloring, a large transparent glass or glass jar.

Experience: Fill the glass 2/3 with water, pour into the water vegetable oil. Oil will float on the surface. Add food coloring to water and oil. Then slowly add 1 teaspoon of salt.

Explanation: Oil is lighter than water, so it floats on the surface, but salt is heavier than oil, so when you add salt to a glass, the oil and salt begin to sink to the bottom. As the salt breaks down, it releases oil particles and they rise to the surface. Food coloring will help make the experience more visual and spectacular.

2. Personal rainbow

Needed: A container filled with water (bathtub, basin), a flashlight, a mirror, a sheet of white paper.

Experience: Pour water into a container and place a mirror on the bottom. We direct the light of the flashlight onto the mirror. The reflected light must be caught on the paper on which a rainbow should appear.

Explanation: A ray of light consists of several colors; when it passes through the water, it breaks down into its component parts - in the form of a rainbow.

3. Vulcan

Needed: Tray, sand, plastic bottle, food coloring, soda, vinegar.

Experience: A small volcano should be molded around a small plastic bottle from clay or sand - for the surroundings. To cause an eruption, you should pour two tablespoons of soda into the bottle, pour in a quarter cup warm water, add a little food coloring, and at the end pour in a quarter cup of vinegar.

Explanation: When baking soda and vinegar come into contact, a violent reaction begins, releasing water, salt and carbon dioxide. Gas bubbles push the contents out.

4. Growing crystals

Needed: Salt, water, wire.

Experience: To obtain crystals, you need to prepare a supersaturated salt solution - one in which the salt does not dissolve when adding a new portion. In this case, you need to keep the solution warm. To make the process go better, it is desirable that the water be distilled. When the solution is ready, it must be poured into a new container to get rid of the debris that is always in the salt. Next, you can lower a wire with a small loop at the end into the solution. Place the jar in a warm place so that the liquid cools more slowly. In a few days, beautiful salt crystals will grow on the wire. If you get the hang of it, you can grow fairly large crystals or patterned crafts on twisted wire.

Explanation: As the water cools, the solubility of the salt decreases, and it begins to precipitate and settle on the walls of the vessel and on your wire.

5. Dancing coin

Needed: Bottle, coin to cover the neck of the bottle, water.

Experience: The empty, unclosed bottle should be placed in the freezer for a few minutes. Moisten a coin with water and cover the bottle removed from the freezer with it. After a few seconds, the coin will begin to jump and, hitting the neck of the bottle, make sounds similar to clicks.

Explanation: The coin is lifted by air, which compressed in the freezer and occupied a smaller volume, but has now heated up and begun to expand.

6. Colored milk

Needed: Whole milk, food coloring, liquid detergent, cotton swabs, plate.

Experience: Pour milk into a plate, add a few drops of coloring. Then you need to take a cotton swab, dip it in the detergent and touch the swab to the very center of the plate with milk. The milk will begin to move and the colors will begin to mix.

Explanation: Detergent reacts with fat molecules in milk and sets them in motion. This is why skim milk is not suitable for the experiment.

7. Fireproof bill

Needed: Ten-ruble bill, tongs, matches or lighter, salt, 50% alcohol solution (1/2 part alcohol to 1/2 part water).

Experience: Add a pinch of salt to the alcohol solution, immerse the bill in the solution until it is completely saturated. Use tongs to remove the bill from the solution and allow the excess liquid to drain. Set the bill on fire and watch it burn without getting burned.

Explanation: As a result of combustion ethyl alcohol water, carbon dioxide and heat (energy) are formed. When you set fire to a bill, the alcohol burns. The temperature at which it burns is not sufficient to evaporate the water with which the paper bill is soaked. As a result, all the alcohol burns out, the flame goes out, and the slightly damp ten remains intact.

9. Camera obscura

You will need:

A camera that supports long shutter speeds (up to 30 s);

Large sheet of thick cardboard;

Masking tape (for gluing cardboard);

A room with a view of anything;

Sunny day.

1. Cover the window with cardboard so that light does not come from the street.

2. We make a smooth hole in the center (for a room 3 meters deep, the hole should be about 7-8 mm).

3. When your eyes get used to the darkness, you will see an inverted street on the walls of the room! The most visible effect will be achieved on a bright sunny day.

4. Now the result can be shot with a camera at a long shutter speed. A shutter speed of 10-30 seconds is fine.

Experiments at home are great way introduce children to the basics of physics and chemistry, and facilitate understanding of complex abstract laws and terms with the help of visual demonstrations. Moreover, to carry them out you do not need to acquire expensive reagents or special equipment. After all, without thinking, we carry out experiments every day at home - from adding slaked soda to dough to connecting batteries to a flashlight. Read on to learn how to conduct interesting experiments easily, simply, and safely.

Chemical experiments at home

Does the image of a professor with a glass flask and singed eyebrows immediately come to mind? Don't worry, ours chemical experiments at home are completely safe, interesting and useful. Thanks to them, the child will easily remember what exo- and endothermic reactions are and what the difference is between them.

So let's make hatchable dinosaur eggs that can be used as bath bombs.

For the experience you need:

small dinosaur figurines;
baking soda;
vegetable oil;
lemon acid;
food coloring or liquid watercolor paints.

Procedure for conducting the experiment

Place ½ cup baking soda in a small bowl and add about ¼ tsp. liquid paints(or dissolve 1-2 drops food coloring in ¼ teaspoon water), stir the baking soda with your fingers to create an even color.
Add 1 tbsp. l. citric acid. Mix dry ingredients thoroughly.
Add 1 tsp. vegetable oil.
You should succeed crumbly dough, which barely sticks together when pressed. If it doesn’t want to stick together at all, then slowly add ¼ tsp. butter until you reach the desired consistency.
Now take the dinosaur figurine and mold the dough into an egg shape. It will be very fragile at first, so you should set it aside overnight (at least 10 hours) to harden.
Then you can start a fun experiment: fill the bathtub with water and throw an egg into it. It will fizz furiously as it dissolves in the water. It will be cold when touched because it is an endothermic reaction between acid and alkali, absorbing heat from the surrounding environment.

Please note that the bath may become slippery due to the addition of oil.

Elephant toothpaste

Experiments at home, the results of which can be felt and touched, are very popular with children. These include this fun project that ends big amount dense lush colored foam.

To carry it out you will need:

safety glasses for children;
dry active yeast;
warm water;
hydrogen peroxide 6%;
dishwashing detergent or liquid soap (not antibacterial);
funnel;
plastic glitter (necessarily non-metallic);
food colorings;
0.5 liter bottle (it is best to take a bottle with a wide bottom for greater stability, but a regular plastic one will do).

The experiment itself is extremely simple:

1 tsp. dilute dry yeast in 2 tbsp. l. warm water.
In a bottle placed in a sink or dish with high sides, pour ½ cup of hydrogen peroxide, a drop of dye, glitter and a little dishwashing liquid (several presses on the dispenser).
Insert the funnel and pour in the yeast. The reaction will begin immediately, so act quickly.

Yeast acts as a catalyst and accelerates the release of hydrogen peroxide, and when the gas reacts with soap, it creates great amount foam. This is an exothermic reaction, releasing heat, so if you touch the bottle after the “eruption” has stopped, it will be warm. Since the hydrogen immediately evaporates, you're left with just soap scum to play with.

Physics experiments at home

Did you know that lemon can be used as a battery? True, very low-power. Experiments at home with citrus fruits will demonstrate to children the operation of a battery and a closed electrical circuit.

For the experiment you will need:

lemons - 4 pcs.;
galvanized nails - 4 pcs.;
small pieces of copper (you can take coins) - 4 pcs.;
alligator clips with short wires (about 20 cm) - 5 pcs.;
small light bulb or flashlight - 1 pc.

Let there be light

Here's how to do the experiment:

Roll on a hard surface, then squeeze the lemons lightly to release the juice inside the skins.
Insert one galvanized nail and one piece of copper into each lemon. Place them on the same line.
Connect one end of the wire to a galvanized nail and the other to a piece of copper in another lemon. Repeat this step until all the fruits are connected.
When you're done, you should be left with 1 nail and 1 piece of copper that are not connected to anything. Prepare your light bulb, determine the polarity of the battery.
Connect the remaining piece of copper (plus) and the nail (minus) to the plus and minus of the flashlight. Thus, a chain of connected lemons is a battery.
Turn on a light bulb that will run on fruit energy!

To repeat such experiments at home also potatoes will do, especially green.

How it works? Lemon acid, contained in lemon, reacts with two different metals, which causes the ions to move in one direction, creating an electric current. All chemical sources of electricity operate on this principle.

Summer fun

You don't have to stay indoors to do some experiments. Some experiments will work better outside, and you won't have to clean anything up after they're done. These include interesting experiments at home with air bubbles, not simple ones, but huge ones.

To make them you will need:

2 wooden sticks 50-100 cm long (depending on the age and height of the child);
2 metal screw-in ears;
1 metal washer;
3 m of cotton cord;
bucket with water;
any detergent - for dishes, shampoo, liquid soap.

Here's how to spend spectacular experiments for children at home:

Screw metal tabs into the ends of the sticks.
Cut the cotton cord into two parts, 1 and 2 m long. You may not strictly adhere to these measurements, but it is important that the proportion between them is maintained at 1 to 2.
Place a washer on a long piece of rope so that it hangs evenly in the center, and tie both ropes to the eyes on the sticks, forming a loop.
Stir in a bucket of water a large number of detergent
Gently immerse the loop on the sticks in the liquid and begin to blow giant bubbles. To separate them from each other, carefully bring the ends of the two sticks together.

What is the scientific component of this experiment? Explain to children that bubbles are held together by surface tension, the attractive force that holds the molecules of any liquid together. Its effect is manifested in the fact that spilled water collects into drops, which tend to take on a spherical shape, as the most compact of all existing in nature, or in the fact that water, when poured, collects into cylindrical streams. The bubble has a layer of liquid molecules on both sides sandwiched by soap molecules, which increase its surface tension when distributed over the surface of the bubble and prevent it from quickly evaporating. While the sticks are kept open, the water is held in the form of a cylinder; as soon as they are closed, it tends to a spherical shape.

These are the kinds of experiments you can do at home with children.

Entertaining experiments for preschoolers, experiments for children at home, magic tricks for children, fun science... How to curb the ebullient energy and irrepressible curiosity of a baby? How to make the most of the inquisitiveness of a child’s mind and push the child to understand the world? How to promote the development of a child’s creativity? These and other questions certainly arise before parents and educators. This work contains a large number of different experiences and experiments that can be carried out with children to expand their understanding of the world, for the intellectual and creative development of the child. The experiments described do not require any special preparation and almost no material costs.

How to puncture a balloon without harming it?

The child knows that if you puncture the balloon, it will burst. Place a piece of tape on both sides of the ball. And now you can easily push the ball through the tape without any harm to it.

"Submarine" No. 1. Grape submarine

Take a glass of fresh sparkling water or lemonade and drop 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 land on it. air balloons. Soon there will be so many of them that the grape will float up.

But on the surface the bubbles will burst and the gas will fly away. The heavy grape will sink to the bottom again. Here it will again become covered with gas bubbles and float up again. This will continue several times until the water runs out. This principle is how a real boat floats up and rises. And fish have a swim bladder. When she needs to submerge, the muscles contract, squeezing the bubble. Its volume decreases the fish is coming down. But you need to get up - the muscles relax, the bubble dissolves. It increases and the fish floats up.

"Submarine" No. 2. Egg submarine

Take 3 cans: two half-liter and one liter. Fill one jar clean water and put it in it a raw egg. It will drown.

Pour a strong solution into the second jar table salt(2 tablespoons per 0.5 liters of water). Place the second egg there and it will float. This is explained by salty water heavier, which is why it is easier to swim in the sea than in a river.

Now put it on the bottom liter jar egg. By 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 remain suspended in the middle of the solution.

When the experiment is completed, you can show the trick. By adding salt water, you will ensure that the egg floats. Adding fresh water will cause the egg to sink. Externally salty and fresh water are no different from each other and it will look amazing.

How to get a coin out of water without getting your hands wet? How to get away with it?

Place a coin in the bottom of a 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 it on fire, throw it into a half-liter jar and immediately place it with the hole down 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 in atmospheric pressure inside the can, water will be drawn into the can. Now you can take the coin without getting your hands wet.

Lotus flowers

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

Natural magnifying glass

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

Place the insect in 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 is formed. 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 can be achieved if you look at an object through a jar of water, securing it to the back wall of the jar 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 act as a candlestick. Light the wick and the candle will burn for quite a long time. It seems that it is about to burn down to the water and go out. But this 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 water for drinking?

Dig a hole in the ground approximately 25 cm deep and 50 cm in diameter. Place an empty Plastic container or a wide bowl, place fresh green herbs and leaves around it. Cover the hole with clean plastic wrap and fill the edges with soil to prevent air from escaping from the hole. Place a pebble in the center of the film and lightly press the film over the empty container. The water collecting device is ready.

Leave your design until the evening. Now carefully shake off the soil from 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 your child that under the influence of the sun's heat, the grass and leaves began to decompose, releasing heat. Warm air always rises. It settles in the form of evaporation on the cold film and condenses on it in the form of water droplets. This water flowed into your container; remember, you slightly pressed the film and put the stone there.

Now you just have to figure it out interesting story about travelers who went to distant countries and forgot to take water with them, and begin an exciting journey.

Wonderful matches

You will need 5 matches.

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

Place 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, called capillarity, is that wood fibers absorb moisture. It creeps further and further through the capillaries. The tree swells, and its surviving fibers “get fat”, and they can no longer bend much and begin to straighten out.

The head of the wash basins. Making a washbasin is easy

Babies have one peculiarity: they always get dirty when there is even the slightest opportunity. And taking a child home to wash all day is quite troublesome, and besides, children don’t 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 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 with your finger, fill it to the top with water and close the lid. By unscrewing it slightly, you get a trickle of water by screwing it on - you will “close the tap” of your washbasin.

Where did the ink go? Transformations

Add ink or ink to a bottle of water until the solution is pale blue. Place a crushed tablet there. activated carbon. Close the neck with your finger and shake the mixture.

It will brighten before our eyes. The fact is that coal absorbs dye molecules on its surface and it is no longer visible.

Making a cloud

Pour into a three-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 will begin to cool as it rises. The water vapor it contains will condense to form a cloud.

This experiment simulates the process of cloud formation during cooling warm air. Where does rain come from? It turns out that the drops, having heated up on the ground, rise upward. There they get cold, and they huddle together, forming clouds. When they meet together, they increase in size, become heavy and fall to the ground as rain.

I don't believe my hands

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

Water suction

Place the flower in water tinted with any paint. Observe how the color of the flower changes. Explain that the stem has conducting tubes through which water rises to the flower and colors it. This phenomenon of water absorption is called osmosis.

Vaults and tunnels

Glue a tube out of thin paper, slightly larger in diameter than a pencil. Insert a pencil into it. Then carefully fill the pencil tube with sand so that the ends of the tube protrude out. Pull out the pencil and you will see that the tube remains uncrumpled. Grains of sand form protective arches. Insects trapped in sand emerge from under the thick layer unharmed.

Equal share for everyone

Take a regular hanger, two identical containers (these can also be large or medium-sized disposable cups and even aluminum drink cans, although the top of the cans must be cut off). In the upper part of the container on the side, opposite each other, make two holes, insert any rope into them and attach to a hanger, which you hang, for example, on the back of a chair. Balance containers. Now pour berries, candies, or cookies into these improvised scales, and then the children won’t argue about who got the most goodies.

"Good boy and Vanka-Vstanka." Obedient and naughty egg

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

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

Fill the shell about one-quarter full of clean, dry sand. Seal the second hole in the same way as the first. The 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 maintain balance.

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

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

If your child wants, let him paint both eggs or glue 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 a boiled egg has a constant center of gravity, so it rotates. And in a raw egg, the internal liquid mass acts as a kind of brake, so the raw egg cannot spin.

“Stop, hands up!”

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

Place it on the table, turning it upside down, and wait. The gas released during the chemical reaction of the tablet and water will push the bottle out, a “rumble” will be heard and the bottle will be thrown up.

"Magic Mirrors" or 1? 3? 5?

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

This is where the real miracle begins, but only just begins. There are three apples. And if you gradually decrease the angle between the mirrors, 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 perform the experiment described above.

How to scrub green grass off your knee?

Take fresh leaves any green plant, be sure to put them in a thin-walled glass and pour a small amount vodka. Place the glass in a pan of hot water (on water bath), but not directly to the bottom, but onto some kind of wooden circle. When the water in the saucepan has cooled, use tweezers to remove the leaves from the glass. They will become discolored, and the vodka will turn emerald green, as chlorophyll has been released from the leaves, green dye plants. It helps plants “feed” on solar energy.

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

Where did the smell go?

Take the corn pops, put them in a jar that has previously had a drop of cologne in it, and close it with a tight lid. After 10 minutes, opening the lid, you will not feel the smell: it has been absorbed by the porous substance 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. Throw them onto the floor from the same height.

How did the ball and ball behave, what changes happened to them after the fall? Why doesn't the plasticine bounce, but the ball does - maybe because it's round, or because it's red, or because it's 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 bounce like a ball. Then explain to the child that the same thing happens to the ball as to him: he bends his knees, and the ball is pressed in a little, when it falls to the floor, he straightens his knees and jumps, and what was pressed in the ball is straightened. The ball is elastic.

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

Touch the child’s head, but don’t let him bounce like a wooden ball. If you don't bend your knees, then it's impossible to jump. You can’t straighten knees that aren’t bent. A wooden ball, when it falls on the floor, is not pressed in, which means it does not straighten out, which is why it does not bounce. It's not elastic.

The concept of electric charges

Inflate a small balloon. Rub the ball on wool or fur, or even better, on your hair, and you will see how the ball begins to stick to literally every object in the room: to the closet, to the wall, and most importantly, to the child.

This is explained by the fact that all objects have a certain electric charge. As a result of contact between two various materials electrical discharges are separated.

Dancing foil

Slice aluminum foil(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 positive and negative electrical charges to each other.

Hanging on your head, or Is it possible to hang on your head?

Make a light top out of cardboard by placing it on thin stick. Sharpen the lower end of the stick, and insert 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 stove soot with talcum powder. Have the child breathe on a finger and press it to a piece of white paper. Sprinkle this area with the prepared black mixture. Shake the sheet of paper until the mixture well covers the area where your finger was applied. Pour the remaining powder back into the jar. There will be a clear fingerprint on the sheet.

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

It's more fun together

Cut a circle out of thick cardboard around the rim of the tea cup. On one side, in the left half of the circle, draw a figure of a boy, and on the other side, a figure of a girl, 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 in loops.

Now stretch the elastic bands in different directions. The cardboard circle will spin quickly, the pictures from different sides will align, and you will see two figures standing next to each other.

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

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

Unusual drawing

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

Pick some petals from different colors: yellow, orange, red, blue, blue, and green leaves of different shades. Just remember that some plants are poisonous, such as aconite.

Sprinkle this mixture onto a cloth placed on cutting board. You can either spontaneously sprinkle petals and leaves or build a planned composition. Cover it with plastic wrap, secure the sides with buttons and roll it all out with a rolling pin or tap 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 the young talent is ready!

It turned out to be a wonderful gift for mom and grandma.

When choosing a gift for my eleven-year-old nephew, I couldn’t do without a book))). It was decided to search among books aimed at distracting the guy as much as possible from modern gadgets. Since he is very smart and inquisitive, I hope that he will spend his summer holidays not bored without a tablet, but with the help of this book and another gift, but that’s another topic. I settled on “Fun scientific experiments for children. 30 exciting experiments at home”, Egor Belko, Petersburg publishing house.

ISBN 978-5-496-01343-7

Home experiments. There is probably no child who would not be interested and would not want to build an erupting volcano at home or “settle” a cloud in a jar, a rainbow in a glass, push an egg into a bottle or grow a purple daisy. And even more so when everything that is needed for these experiments is at home: on the desktop or in mom’s kitchen, and no special reagents or chemicals are needed. The most “dangerous” means for conducting experiments in this book is perhaps vinegar.

On each spread it is given detailed description experiment: necessary materials, a description of the preparation and progress of the experiment and its scientific explanation, as well as clear and colorful illustrated tips. All experiments are very simple, and everything needed to carry them out can be easily found in every home. From the age of 6-7, I think, you can already give a book to a child for independent study, and before this age you can have a great time with mom, or even better with dad (dads are better able to explain the properties of objects and materials, they somehow it turns out simpler and clearer)))

My daughter is almost 3 years old, but we also love to experiment. For example, we have already done, we built an entire installation of a mountain peak and a volcano erupting in it, and with ice and simply painted with “soda” paints, and then “foamed” the drawing with vinegar or, perhaps, a solution of citric acid. The child’s delight is guaranteed, and even if he does not understand the reason for what is happening, he will certainly remember the impressions of what he saw. The goal and task of such activities with a child is to simply and clearly show that any phenomenon in nature or human life has a simple explanation, and we can understand its components; awaken the child’s interest in everything that has a logical scientific explanation, but does not give impetus to curiosity at first sight; teach the child to seek the truth of what is happening; and just to make it clear that from any object or material found in the kitchen, yard or bathroom, you can make something interesting and exciting with your own hands. We have already sent the book to my nephew, but I photographed all the spreads so that I could repeat the experiments with my daughter. There is a lot of information about such things on the Internet now, and if you try, you can compile your own book of “home experiments,” but if you don’t want to spend a lot of time searching or just have a holiday coming up for your beloved children, then this book is worthy of attention.

We bring to your attention 10 amazing magic experiments, or science shows, that you can do with your own hands at home.
Whether it's your child's birthday party, the weekend or the holidays, have a good time and become the center of attention of many eyes! 🙂

An experienced organizer of scientific shows helped us in preparing this post - Professor Nicolas. He explained the principles that are inherent in this or that focus.

1 - Lava lamp

1. Surely many of you have seen a lamp with a liquid inside that imitates hot lava. Looks magical.

2. B sunflower oil water is poured and food coloring (red or blue) is added.

3. After this, add effervescent aspirin to the vessel and observe an amazing effect.

4. During the reaction, the colored water rises and falls through the oil without mixing with it. And if you turn off the light and turn on the flashlight, the “real magic” will begin.

: “Water and oil have different densities, and they also have the property of not mixing, no matter how much we shake the bottle. When we add effervescent tablets inside the bottle, they dissolve in water and begin to release carbon dioxide and set the liquid in motion.”

Do you want to put on a real science show? More experiments can be found in the book.

2 - Soda experience

5. Surely there are several cans of soda at home or in a nearby store for the holiday. Before you drink them, ask the kids a question: “What happens if you immerse soda cans in water?”
Will they drown? Will they float? Depends on the soda.
Invite the children to guess in advance what will happen to a particular jar and conduct an experiment.

6. Take the jars and carefully lower them into the water.

7. It turns out that despite the same volume, they have different weights. This is why some banks sink and others don't.

Professor Nicolas's comment: “All our cans have the same volume, but the mass of each can is different, which means that the density is different. What is density? This is the mass divided by the volume. Since the volume of all cans is the same, the density will be higher for the one whose mass is greater.
Whether a jar will float or sink in a container depends on the ratio of its density to the density of water. If the density of the jar is less, then it will be on the surface, otherwise the jar will sink to the bottom.
But what makes a can of regular cola denser (heavier) than a can of diet drink?
It's all about the sugar! Unlike regular cola, which uses granulated sugar, a special sweetener is added to the diet, which weighs much less. So how much sugar is in a regular can of soda? The difference in mass between regular soda and its diet counterpart will give us the answer!”

3 - Paper cover

Ask those present: “What happens if you turn a glass of water over?” Of course it will pour out! What if you press the paper against the glass and turn it over? Will the paper fall and water will still spill on the floor? Let's check.

10. Carefully cut out the paper.

11. Place on top of the glass.

12. And carefully turn the glass over. The paper stuck to the glass as if magnetized, and the water did not spill out. Miracles!

Professor Nicolas's comment: “Although this is not so obvious, in fact we are in a real ocean, only in this ocean there is not water, but air, which presses on all objects, including you and me, we are just so used to it to this pressure that we don’t notice it at all. When we cover a glass of water with a piece of paper and turn it over, water presses on the sheet on one side, and air on the other side (from the very bottom)! The air pressure turned out to be greater than the water pressure in the glass, so the leaf does not fall.”

4 - Soap Volcano

How to make a small volcano erupt at home?

14. You will need baking soda, vinegar, some cleaning chemicals for dishes and cardboard.

16. Dilute vinegar in water, add washing liquid and tint everything with iodine.

17. We wrap everything in dark cardboard - this will be the “body” of the volcano. A pinch of soda falls into the glass and the volcano begins to erupt.

Professor Nicolas's comment: “As a result of the interaction of vinegar with soda, a real chemical reaction with the release of carbon dioxide. And liquid soap and dye, interacting with carbon dioxide, form colored soap foam - and that’s the eruption.”

5 - Spark plug pump

Can a candle change the laws of gravity and lift water up?

19. Place the candle on the saucer and light it.

20. Pour colored water onto a saucer.

21. Cover the candle with a glass. After some time, the water will be drawn inside the glass, contrary to the laws of gravity.

Professor Nicolas's comment: “What does the pump do? Changes the pressure: increases (then water or air begins to “escape”) or, conversely, decreases (then gas or liquid begins to “arrive”). When we covered the burning candle with a glass, the candle went out, the air inside the glass cooled, and therefore the pressure decreased, so the water from the bowl began to be sucked in.”

Games and experiments with water and fire are in the book "Professor Nicolas' Experiments".

6 - Water in a sieve

We continue to study the magical properties of water and surrounding objects. Ask someone present to pull the bandage and pour water through it. As we can see, it passes through the holes in the bandage without any difficulty.
Bet with those around you that you can make sure that water does not pass through the bandage without any additional techniques.

22. Cut a piece of bandage.

23. Wrap a bandage around a glass or champagne flute.

24. Turn the glass over - the water doesn’t spill out!

Professor Nicolas's comment: “Thanks to this property of water, surface tension, water molecules want to be together all the time and are not so easy to separate (they are such wonderful girlfriends!). And if the size of the holes is small (as in our case), then the film does not tear even under the weight of water!”

7 - Diving bell

And to secure the honorary title of Water Mage and Lord of the Elements for you, promise that you can deliver paper to the bottom of any ocean (or bathtub or even basin) without getting it wet.

25. Have those present write their names on a piece of paper.

26. Fold the piece of paper and put it in the glass so that it rests against its walls and does not slide down. We immerse the leaf in an inverted glass to the bottom of the tank.

27. The paper remains dry - water cannot reach it! After you pull out the leaf, let the audience make sure that it is really dry.
