Interesting experiments with water for kids. Chemical experiments for children at home. Sets for schoolchildren: Volcano, Chemistry, Traffic light. Balloon experiments for kids

For the development of the child, it is necessary to use all possible means, including experiments for children, which can be carried out at home by trained parents. This type of activity is very interesting for preschoolers, it helps them to learn a lot about the world around them, to take a direct part in the research process. The main rule that moms and dads should follow is the absence of coercion: classes should be held only when the child himself is ready for experiments.

Physical

Such scientific experiments will interest the inquisitive baby, help him gain new knowledge:

• about the properties of the liquid;
• about atmospheric pressure;
• on the interaction of molecules.

In addition, under clear parental guidance, he can easily repeat everything.

Bottle filling

Prepare your inventory in advance. You will need hot water, a glass bottle and a bowl of cold water(for clarity, the liquid should first be tinted).

The procedure is as follows:

1. Must be bottled hot water several times to warm up the container properly.
2. Pour out hot liquid completely.
3. Turn the bottle upside down and lower it into a bowl of cold water.
4. It will be possible to see that water from the bowl will begin to fill the bottle.

Why is this happening? Due to the action of the hot liquid, the bottle was filled with warm air. Cooling down, the gas is compressed, as a result of which the volume occupied by it decreases, forming a medium in the bottle with reduced pressure. Water, acting, restores balance. This experiment with water can be done at home without any problems.

With a glass

Every kid, even at 3-4 years old, knows that if you turn over a glass filled with water, the liquid will pour out. However, there interesting experience capable of proving the opposite.

Procedure:

1. Pour water into a glass.
2. Cover it with a piece of cardboard.
3. Holding the sheet with your hand, carefully turn the structure over.
4. You can remove your hand.

Surprisingly, the water will not pour out - the molecules of cardboard and liquid will mix at the moment of contact. Therefore, the sheet will hold on, becoming a kind of cover. The child can also be told about atmospheric pressure, that it is both inside the glass and outside, while in the container it is lower, outside it is higher. Due to this difference, water does not pour out.

A similar experiment is best done over the pelvis, because gradually paper material get wet and liquid will drip.

Developmental experiments

There is a large number of for real interesting experiments for babies.

Eruption

This experience is rightfully considered one of the most exciting and therefore loved by children. To carry it out you will need:

• soda;
• red paint;
• citric acid or lemon juice;
• water;
• some detergent.

First, you should build the “volcano” itself, by making a cone of thick paper, fastening it around the edges with tape and cutting a hole from the top. Then the resulting blank is put on any bottle. To look like a volcano, it should be covered with brown plasticine and placed on a large baking sheet so that the “lava” does not spoil the surface of the table.

Procedure:

1. Pour soda into a bottle.
2. Add paint.
3. Drop detergent (1 drop).
4. Pour in water and mix well.

To start the "eruption", you need to ask the child to add a little citric acid(or lemon juice). This is the simplest example chemical reaction.

Dancing worms

This simple fun experiment can be done with both preschoolers and younger students. Necessary equipment:

• corn starch;
• water;
• baking sheet;
• paints (food coloring);
• music column.

First you need to mix 2 cups of starch and a glass of water. Pour the resulting substance on a baking sheet, add paint or dye.

It remains only to turn on loud music and attach a baking sheet to the column. The colors on the blank will mix in a chaotic manner, creating a beautiful unusual spectacle.

We use food

To make an experiment - unusual, interesting for the baby and informative - it is not at all necessary to purchase sophisticated equipment and expensive materials. We invite you to get to know simple options available for execution at home.

with egg

Necessary equipment:

• a glass of water (high);
• egg;
• salt;
• water.

The bottom line is simple - an egg immersed in water will sink to the bottom. If you add table salt to the liquid (about 6 tablespoons), then it will rise to the surface. Such physical experience with salt helps to illustrate the concept of density to the baby. So, in salted water, it is more, so the egg can stay on the surface.

You can also show the opposite effect (which is why it was recommended to take a tall glass) - when added to a salted liquid, a simple tap water density will decrease and the egg will sink to the bottom.

invisible ink

A very interesting and simple trick that at first will seem like real magic to the baby, and after the explanation of the parents will help to learn about oxidation.

Necessary equipment:

• ½ lemon;
• water;
• spoon and plate;
• paper;
• lamp;
• cotton swab.

If there is no lemon, you can use analogues, for example, milk, onion juice or wine.

Procedure:

1. Squeeze citrus juice, add it to a plate, mix with an equal amount of water.
2. Dip the swab into the resulting liquid.
3. Write with it something understandable to the child (or draw).
4. Wait for the juice to dry, becoming completely invisible.
5. Heat the sheet (using a lamp or holding it over a fire).

Text or a simple drawing will become visible due to the fact that the juice has oxidized and turned brown when the temperature rises.

color explosion

The little ones can enjoy a fun experience with milk and paints, which can be easily carried out in the kitchen.

Necessary products and equipment:

• milk (preferably high fat);
• food coloring (several colors - the more, the more interesting and brighter it will turn out);
• dishwashing liquid;
• plate;
• cotton buds;
• pipette.

If dishwashing liquid is not available, it is acceptable to use liquid soap.

Procedure:

1. Pour milk into a bowl. It should completely hide the bottom.
2. Let the liquid stand for a while to bring it to room temperature.
3. Using a pipette, carefully drop several different food colors into a plate of milk.
4. Lightly touching the liquid with a cotton swab, you need to show the baby what is happening.
5. Next, a second stick is taken, dipped in detergent. It touches the surface of the milk, delays for 10 seconds. It is not necessary to mix colorful stains, a careful touch is enough.

Then the kid will be able to watch the most beautiful - the colors begin to "dance", as if trying to escape from the soap stick. Even if you remove it now, the "explosion" will continue. At this stage, you can invite the child to participate on his own - add dye, immerse a soap stick in the liquid.

The secret of experience is simple - detergent destroys the fat contained in milk, which causes the "dance".

With sugar

For children 3-4 years old, various experiments with food will be very interesting. The child is happy to learn about the new qualities of his usual food.

For this entertaining entertainment would need:

• 10 st. l. Sahara;
• water;
• food coloring in several colors;
• two spoons (tea, tablespoon);
• syringe;
• 5 glasses.

First you need to add sugar to the glasses according to this scheme:

• in the first glass - 1 tbsp. l.;
• in the second - 2 tbsp. l.;
• in the third - 3 tbsp. l.;
• in the fourth - 4 tbsp. l.

Add 3 tsp to each of them. water. Mix. Then you need to add a dye of your color to each of the glasses and mix again. The next step is to carefully take the colored liquid from the fourth glass with a syringe or a teaspoon and pour it into the fifth, which was empty. Then, in a similar order, colored water is added from the third, second and, finally, from the first glasses.

If you act carefully, colored liquids will not mix, but, layering on top of each other, will help create a bright unusual pyramid. The secret of the trick is that the density of water changes depending on the amount of sugar added to it.

With flour

Consider another interesting experience for children, simple and safe. It can be carried out as kindergarten, as well as at home.

Necessary equipment:

• flour;
• salt;
• paints (gouache);
• brush;
• sheet of cardboard.

Procedure:

1. In a small glass, mix 1 tbsp. l. flour and salt. This is a blank, from which in the future we will make paint of the same color. Accordingly, the number of such blanks is equal to the number of colors.
2. In each glass, add 3 tbsp. l. water and gouache.
3. With the help of paint, ask the child to draw a picture on cardboard using a brush or cotton swab, for each color.
4. Place the finished creation in the microwave (power 600 W) for 5 minutes.

The paints, which are the dough, will rise and harden, making the drawing voluminous.

Lava lamp

Another unusual children's experiment allows you to create a real lava lamp. After looking just once, even a novice researcher will be able to repeat the experience with his own hands, without the help of adults.

Necessary equipment and materials:

• vegetable oil (glass);
• salt (1 tsp);
• water;
• food coloring (several shades);
• glass jar.

Procedure:

1. Fill the jar 2/3 full with water.
2. Add vegetable oil, which at this stage forms a thick film on the surface.
3. Add food coloring.
4. Slowly pour in the salt.

Under the weight of salt, the oil will begin to sink to the bottom, and the dye will make the spectacle more colorful and spectacular.

With soda

To demonstrate to a child preschool age experiment with soda is perfect:

1. Pour the drink into a glass.
2. Dip a few peas or cherry pits into it.
3. Watch how they gradually rise from the bottom and fall again.

An amazing sight for a kid who does not know yet, peas are surrounded by bubbles of carbon dioxide, which brings them to the surface. Submarines operate on a similar principle.

With water

There are several cognitive optical experiments, which, for their simplicity, are very curious.

• The missing ruble

Water is poured into the jar, an iron ruble is lowered into it. Now you need to ask the baby to find a coin by looking through the glass. Due to the optical phenomenon of refraction, the eye will not be able to see the ruble if it is directed from the side. If you look into the jar from above, the coin will be in place.

• curved spoon

Let's continue to explore optics with a preschooler. This easy but visual experiment is carried out as follows: you need to pour water into a glass and lower a spoon into it. Ask your child to look sideways. He will see that at the border of the media - water and air - the spoon seems to be curved. Taking out a spoon, you can make sure that everything is in order with it.

The child should be explained that a ray of light is bent when passing through water, which is why we see a changed image. You can continue the water theme and lower the same spoon into a small jar. Curvature will not occur, since the walls of this container are even.

This biological experiment will help the child get acquainted with the world of wildlife, observe how a sprout is formed. For carrying out, beans or peas are needed.

Parents can offer the young botanist to moisten a piece of gauze folded several times with water, put it on a saucer, place it on a pea or bean cloth and cover with wet gauze. The task of the baby is to carefully monitor that the seeds are moistened all the time, check them regularly. After a couple of days, the first shoots will appear.

Photosynthesis process

This plant and candle experience is best for younger students who know that trees and grass absorb carbon dioxide and release oxygen.

The gist is this:

1. Carefully place burning candles in two jars.
2. In one of them put a living plant.
3. Cover both containers.

Observe that in a jar with a plant, the candle continues to burn, since oxygen is present in it. In the second bank, it goes out almost immediately.

Entertaining

We catch electricity. This small and safe experience may well be carried out with toddlers.

1. One inflated is placed on the wall balloon, several others lie on the floor.
2. Mom invites the child to put all the balls on the wall. However, they will not hold and fall.
3. Mom asks the baby to rub the ball on her hair and try again. Now the ball has been attached.

After that, you need to tell that the “miracle” happened due to the electricity that was generated when the ball was rubbed against the hair.

Another option for the curious is the foil experiment. It is done like this:

1. A small piece of foil should be cut into strips.
2. Ask the baby to comb her hair.
3. Now you need to lean the comb against the strip and watch. The foil will stick to the comb.

You can also demonstrate to the children the “Missing Chalk”. To do this, a piece of ordinary chalk is placed in vinegar. The limestone will begin to sizzle, shrink in size. After a while, it will completely dissolve. This is due to the fact that chalk, when in contact with vinegar, turns into other substances.

Experiments with preschool children are a great opportunity to develop their curiosity, to answer many questions in a clear and understandable way. In addition, by offering kids a variety of experiments, attentive parents will help them in early age outline your own interests. And the research itself will be a great and fun pastime.

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

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

refractory ball

It will take: 2 balls, candle, matches, water.

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

The pencils

You will need: plastic bag, pencils, water.

Experience: Pour water halfway into a plastic bag. We pierce the bag through with a pencil 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 halfway with water and then pierce it with a sharp object so that the object remains stuck in 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 pulled around the pencils.

Non-popping ball

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

Experience: Lubricate 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 save 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

It will take: 4 cups of water, food coloring, cabbage leaves or white flowers.

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

Explanation: Plants absorb water and thus nourish their flowers and leaves. This is due to the capillary effect, in which the water itself tends to fill the thin tubes inside the plants. This is how flowers, and grass, and big trees. By sucking in tinted water, they change their color.

floating egg

It will take: 2 eggs, 2 glasses of water, salt.

Experience: Gently place the egg in a glass with a simple 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 dip the second egg into 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 brine higher, and so the egg rises.

crystal lollipops

It will take: 2 cups water, 5 cups sugar wooden sticks for mini-kebabs, thick paper, transparent glasses, a saucepan, food coloring.

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

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

lit match

Need: 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, as it does not prevent light from passing through it.

In the summer, home experiments with water for children come in handy. All kids like to play and tinker in the water in hot weather. Conducting such “research” allows them to get acquainted with the most important properties of water. Therefore, we will present them before moving on to interesting, informative, fun, visual experiments.

Water properties

Water is the basis of life. It is the "base" for the good work of the human body. Three states of water are known: liquid, gaseous and solid. Consider the following properties of water.

1. Transparency. Take two glasses. Pour water into one, milk into the other. Give the crumbs a bead and offer to lower it in turn into both glasses. The bead can be easily seen in a glass of water, as the water is crystal clear.
2. Colorless. To confirm, pour water into the glasses and different colors paint it. Leave the water in one glass colorless and transparent, that is, the way it was.

There are objects that sink in water, and some remain on the surface and float. Dip various things into the water - pebbles, pieces of paper, cones, objects made of metal, wood, and watch which of them sink and which do not.

Home experiments with water

Experience 1. With ordinary paint

Take ordinary paint and drip into the water one drop at a time. Watch how it gradually mixes up. The color in the water becomes less bright. The more colors, the brighter the color becomes.

Experience 2. In search of treasure

Students will be interested in doing this experience. To do this, you need buttons, pebbles, sparkles, shells. Pour water into a glass and pour out the treasure. Next, put it in the freezer. Wait for the water to freeze. As soon as it freezes, you begin to take out a piece of ice with a spoon or tweezers, and then lower it into warm water. When it starts to melt, you get "treasures".

Experiment 3. Water absorption

Pour water into the container and bring a sponge to it and watch what happens. Water, jumping up, is absorbed into the pores. Then bring various things to the water and watch which are able to absorb it and which do not have absorbent properties.

Experience 4. With ice cubes

Children 5 - 6 years old will be interested in such an experience. Freeze the ice, making special cubes out of them. Take thin cocktail tubes, cut them 5 cm long and insert them into an ice mold. Then put in the freezer. After freezing, you will get strong cubes with a straw. Do they really look like boats? When attaching a sail to a match, launch the boats through puddles or into a tub of water.

Experience 5. "Floating" egg

Take a raw egg. Put it in a glass of water. You will see it sink to the bottom. Then take out the egg and dissolve 2-3 tablespoons of salt there. Dip it again now in a glass of salt water. You will see the egg floating on the water surface.

Hence the conclusion that the density of water increases with the help of salt and therefore it is more difficult to drown in salt water. For example, in the Dead Sea, the water is too salty, therefore, a person can lie on the sea surface and not drown.

Experience 6. "Boiling" cold water

Wet and wring out a handkerchief. Then cover it with a full glass of cold water and fix the handkerchief on the glass with a rubber band. Press your finger into the middle of the handkerchief so that it enters 2-3 cm into the water. Then turn the glass upside down over the sink. Hold the glass with one hand and tap the bottom lightly with the other. And what's going on? The water begins to "boil" or bubbling in the glass.

Explanation: a wet handkerchief does not let water through. When you hit the glass, a vacuum is formed in it and through the handkerchief the air enters the water, absorbed by the vacuum. These air bubbles form an opinion about the "boiling" of water.

Experience 7. Disappearing water

Take two identical glasses and fill them with water to the same level. Mark it with a marker. Cover one glass with a lid and leave the other open. Put them in a warm place. The next day you will see that the level of water in the open glass has become lower, but in the closed glass it has not changed.

What happened? Under the influence of heat, the water in the open glass evaporated and turned into the smallest particles of steam, which dispersed in the air. Hence the conclusion: someday everything wet dries up.

Experience 8. With ice

Drop a piece of ice into a glass filled to the brim with water. The ice will begin to melt, and the water will not overflow. It follows that the water into which the ice has been transformed is heavier and takes less space than ice. Conclusion: ice is lighter than water.

Experience 9. Rainbow

Show the kids a rainbow in the room. Place a mirror into the water at a small angle. Then catch a ray of sunlight with a mirror and point it at the wall. Rotate it until you see a spectrum of light on the wall. The role of the prism, which decomposes light into components, is performed by water. Toddlers will really enjoy this experience as they will see the rainbow.

So that your little ones get useful and interesting information about water, do home experiments with water for children. In this video you will find some more ideas for experiments.

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

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

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

Ice bubbles

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

I give you a hint:

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

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

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

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

Choose answers:

• Yes. But you need ice from the fridge.

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

Paper vs water

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

What we need:

• Paper;
• Water in a glass.

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

Inflate balloons without breathing?

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

Ingredients:

• Soda;
• The bottle is plastic;
• Vinegar;
• Ball.

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

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

Rain from a cloud

We need:

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

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

photo author

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

Rainbow

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

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

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

Even easier is to use a disc and a flashlight.

crystals

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

Can be grown from sugar

lava jar

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

Eruption

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

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

A hole in the bag is not a problem.

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

Water that does not spill

Only such water still needs to be made.

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

"Slippery" egg

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

snow in summer

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

moving snakes

To make a moving figure, we need:

• Sand;
• Alcohol;
• Sugar;
• Soda;
• Fire.

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

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

battery train

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

Candle swing

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

Elephant Tooth Paste

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

Let's drink a candle

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

Real chameleon

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

Light up the rainbow

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

smoke rings

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

colorful liquid

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

Egg without shell

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

Dancing little men

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

Decorating the ice

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

Launching paper rockets

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

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

The Ghostbusters remake is coming out very soon, and this is a great excuse to revisit the old movie and explore non-Newtonian fluids. One of the heroes of the film, the silly ghost Lizun, - good image for visualization. This is a character who loves to eat very much, and he also knows how to penetrate walls.

We will need:

• potato,
• tonic.

What do we do

Very finely (can be chopped in a food processor), cut the potatoes and pour hot water. After 10-15 minutes, drain the water through a sieve into a clean bowl and set aside. A sediment will appear at the bottom - starch. Drain the water, the starch will remain in the bowl. In principle, you will already get a non-Newtonian fluid. You can play with it and watch how it hardens under your hands, and becomes liquid by itself. You can also add food coloring for a vibrant color.

Now let's add some magic.

The starch needs to be dried (leave for a couple of days). And then add tonic to it and make a kind of dough that is easy to take in your hand. In the palms, it will retain its consistency, and if you stop and stop kneading it, it will begin to spread.

If enable ultraviolet lamp, then you and your child will see how the dough begins to glow. This is due to quinine, which is contained in the tonic. It looks magical: a luminous substance that behaves as if it violates all the laws of physics.

2. Get superpowers

Comic book heroes are especially popular right now, so your child will love feeling like a powerful Magneto who can manipulate metals.

We will need:

• printer toner,
• magnet,
• vegetable oil.

What do we do

From the very beginning, get ready for the fact that after conducting this experiment you will need a lot of napkins or rags - it will be quite dirty.

Pour about 50 ml of toner into a small container to laser printers. Add two tablespoons vegetable oil and mix very well. Done - you have a liquid in your hands that will react to the magnet.

You can attach a magnet to the container and watch how the liquid literally sticks to the wall, forming a funny "hedgehog". It will be even more interesting if you find a board on which it is not a pity to pour a little black mixture, and invite the child to use a magnet to control a drop of toner.

3. Turn milk into a cow

Encourage your child to make a liquid solid without resorting to freezing. This is a very simple and impressive experience, although you have to wait a couple of days to get the result. But what an effect!

We will need:

• cup ,
• vinegar.

What do we do

Heat up a glass of milk microwave oven or on the stove. We don't boil. Then you need to add a tablespoon of vinegar to it. And now we start to interfere. Actively move the spoon in the glass to see how white clots appear. This is casein, a protein found in milk.

When there are a lot of clots, drain the mixture through a sieve. All that remains in the colander must be shaken, and then laid out on a paper towel and dried a little. Then start kneading the material with your hands. It will look like dough or clay. At this stage, you can add food coloring or glitter to make the white mass brighter and more interesting for the baby.

Invite the child to mold something from this material - an animal figurine (for example, a cow) or some other object. But you can just lay out the mass in plastic mold. Leave to dry for a day or two.

When the mass dries, you will have a figurine made of a very hard hypoallergenic material. Such "homemade plastic" was used until the 1930s. Jewelry, accessories, buttons were made from casein.

4. Manage snakes

Getting a vinegar and soda reaction is just about the most boring experience imaginable. "Volcanoes" and "pops" will not be of interest to modern children. But you can invite the child to become a “master of snakes” and show how acid and alkali still react.

We will need:

• packaging of jelly worms,
• soda,
• vinegar.

What do we do

We take two large transparent glasses. Pour water into one and pour soda. We mix. Open the package of jelly worms. It is better to cut each of them lengthwise, to make thinner. Then the experience will be more spectacular.

Thin worms should be put in a mixture of water and soda and mixed. Set aside for 5 minutes.

Pour vinegar into another glass. And now we add to this vessel the worms that have been in a glass of soda. Because of the soda, bubbles will be visible on their surface. So there is a reaction. The more worms you add to the glass, the more gas will be released. And after some time, the bubbles will raise the worms to the surface. Add more soda - the reaction will be more active and the worms themselves will begin to crawl out of the glass. Cool!

5. Make a hologram like in Star Wars

Of course, it is difficult to create a real hologram at home. But its likeness is quite real and not even very difficult. You will learn how to use the properties of light and turn 2D images into 3D images.

We will need:

• smartphone,
• cd box,
• stationery knife,
• scotch,
• paper,
• pencil.

What do we do

Draw a trapezoid on paper. The drawing can be seen in the photo: length bottom side trapezoid - 6 cm, upper - 1 cm.

Carefully cut out a paper trapezoid and take out the CD box. We need a transparent part of it. Attach the pattern to the plastic and use a clerical knife to cut a trapezoid out of the plastic. Repeat three more times - we need four identical transparent elements.

Now they need to be glued together with adhesive tape so that it looks like a funnel or a truncated pyramid.

Take a smartphone and run one of the such videos. Place the plastic pyramid, narrow side down, in the center of the screen. Inside you will see a "hologram".

You can run a video with characters from " Star Wars' and, for example, recreate famous recording of Princess Leia, or admire own miniature BB-8.

6. Get away with it

Every child can build a sand castle on the seashore. How about building it under water? Along the way, you can learn the concept of "hydrophobic".

We will need:

• colored sand for aquariums (you can take regular sand, but it needs to be washed and dried),
• hydrophobic shoe spray.

What do we do

Carefully pour the sand onto a large plate or baking sheet. We apply a hydrophobic spray on it. We do this very carefully: spray, mix, repeat several times. The task is simple - to make sure that a protective layer envelops each grain of sand.

When the sand dries, collect it in a bottle or bag. Take a large container for water (for example, a jar with a wide mouth or an aquarium). Show your child how hydrophobic sand "works". If you pour it in a thin stream into water, it will sink to the bottom, but remain dry. This is easy to check: let the baby take some sand from the bottom of the container. As soon as the sand rises from the water, it will crumble in the palm of your hand.

7. Classify information better than James Bond

Write secret messages lemon juice - last century. There is another way to get invisible ink, which also allows you to learn a little more about the reaction of iodine and starch.

We will need:

• paper,
• brush.

What do we do

First we cook rice. Porridge can be eaten later, but we need a decoction - it has a lot of starch. Dip a brush into it and write a secret message on paper, such as "I know who ate all the cookies yesterday." Wait for the paper to dry. The starch letters will be invisible. To decipher the message, you need to moisten another brush or cotton swab in a solution of iodine and water and draw it over what is written. Due to the chemical reaction, blue letters will begin to appear on the paper. Voila!
