A beautiful experience with the combustion of alcohol vapors. Ten funny experiments with fire Experiments with fire Learn more about fire

All children, without exception, love mysterious, enigmatic and unusual phenomena. Most guys really like to spend interesting experiments, some of which without seeking help from parents or other adults.

Experiments you can do with children

Not all experiences are suitable for children. Some of them may pose a danger to the life and health of children, especially preschool age. However, under the control and supervision of parents or other adults, a child can conduct any interesting experiment– the main thing is to carefully monitor compliance necessary requirements security.

All scientific experiments for children are extremely useful. They allow young inventors to visually familiarize themselves with the properties of various substances and objects, chemical compounds and much more, understand the causes of certain phenomena and gain valuable practical experience that can be applied in later life. In addition, some such experiments can be shown as magic tricks, thanks to which the child will be able to gain authority among his friends and acquaintances.

Experiments with water for children

All people use water very often in everyday life and do not think at all about the fact that it has truly magical and amazing properties. Meanwhile, this liquid can be used incredibly with children. For example, boys and girls can conduct the following experiments at home:


Experiments with fire for children

Special care should be taken with fire, but it can be used to create incredibly interesting experiments for children. Try one of the following experiments with your offspring:



Experiments with salt for children

Entertaining experiments for children can also be carried out with bulk substances, for example, salt. The kids will definitely enjoy experiments such as:



Experiments with soda for children

No less spectacular experiments for children can be carried out with baking soda, For example, "Volcano". Place a small one on the table plastic bottle and sculpt a volcano out of clay or sand around it. Pour 2 tablespoons of soda into a container, add approximately 50-70 ml of warm water, a few drops of red food coloring, and at the very end - a quarter cup of vinegar. A real volcanic eruption will happen before your eyes, and your child will be delighted.


Other experiments for children with baking soda can be based on the property of this substance to crystallize. To obtain crystals, You can use the same method as in the case of salt. To do this, you need to prepare a dense soda solution in which the bulk substance no longer dissolves, and then place a metal wire or other object there and leave it for several days in a warm place. The result will not take long to arrive.


Experiments with balloons for children

Often experiences and experiments for children are related to various properties balloons, such as:



Experiments with eggs for children

Some interesting experiments can be carried out with children using chicken eggs, For example:



Experiments with lemon for children

Anything can be used to conduct experiments. Interesting experiments with lemon also deserve special attention, for example:



Experiments with paints for children

All kids love to draw, but it will be even more interesting for them to conduct entertaining experiments with paints. Try one of the following experiments:



And learn with them peace and wonders of physical phenomena? Then we invite you to our “experimental laboratory”, in which we will tell you how to create simple, but very interesting experiments for children.


Experiments with eggs

Egg with salt

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

You will need:

  • Salt
  • Tumbler.

Instructions:

1. Fill half the glass with water.

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

3. We interfere.

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

Explanation

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

Egg in a bottle


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

You will need:

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

Instructions:

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

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

3. Place an egg on the neck.

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

Explanation

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

Ball experiment


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

You will need:

  • Balloon
  • Orange.

Instructions:

1. inflate balloon.

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

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

Explanation.

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

Candle experiment


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

You will need:

  • Regular candle
  • Matches or lighter.

Instructions:

1. Light a candle.

2. After a few seconds, put it out.

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

Explanation

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

Soda with vinegar


A balloon that inflates itself is a very interesting sight.

You will need:

  • Bottle
  • Glass of vinegar
  • 4 teaspoons soda
  • Balloon.

Instructions:

1. Pour a glass of vinegar into the bottle.

2. Pour baking soda into the ball.

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

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

5. We watch the balloon inflate.

Explanation

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

Invisible ink


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

You will need:

  • Half a lemon
  • Spoon
  • A bowl
  • Cotton swab
  • White paper
  • Lamp.

Instructions:

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

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

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

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

Explanation

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

Other substances which work on the same principle:

  • Orange juice
  • Milk
  • Onion juice
  • Vinegar
  • Wine.

How to make lava


You will need:

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

Instructions:

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

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

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

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

Explanation

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

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

Ice experiment


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

You will need:

  • Cup
  • Ice cubes.

Instructions:

1. Fill the glass warm water to the very edge.

2. Carefully lower the ice cubes.

3. Watch the water level carefully.

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

Explanation

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

How to make a parachute


find out about air resistance, making a small parachute.

You will need:

Instructions:

1. Cut a large square from a plastic bag.

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

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

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

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

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

Explanation

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

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

How to make a tornado


Find out, how to make a tornado in a bottle with this fun scientific experiment for children. The items used in the experiment are easy to find in everyday life. Made home mini tornado much safer than the tornadoes shown on television in the American steppes.

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. Water is poured into sunflower oil 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 experiences 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 weight. 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, where granulated sugar is used as a sweetener, a special sweetener is added to diet cola, 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 more pressure water in a glass, the leaf doesn’t fall.”

4 - Soap Volcano

How to make a small volcano erupt at home?

14. You will need baking soda, vinegar, some dishwashing chemicals 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. A liquid soap and the dye, interacting with carbon dioxide, form a colored soap suds- here comes 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 magical properties 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.

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.

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.

Professor Nicolas's comment: “If you take a glass with a piece of paper inside and look at it carefully, it seems that there is nothing but paper, but this is not so, there is air in it.
When we turn the glass upside down and lower it into water, the air prevents the water from getting to the paper, which is why it remains dry.

"Young Fireman"

(experiments with children fire safety)

Experience 1 “How can you put out the fire?”

Target: Show children what means can be used to extinguish a fire.

Materials and equipment: 3 porcelain cups, cologne, sand thick cloth, indoor plant, 2 glasses of water, fire extinguisher.

Progress of the experiment

The teacher invites one child to add paint to a glass of water, and the other to add sugar.

The teacher sets fire to a small amount of cologne in three porcelain cups. The first one is filled with water (from any glass), the second one is covered with sand, and the third one is covered with a thick cloth. The fire goes out in all the cups.

The teacher draws the children's attention to the indoor plant and leads them to the fact that when there is no sand, they can use soil from a flower pot.

Conclusion: Experience shows that when extinguishing a fire, you can use any water, as well as sand (earth) and thick fabric.

Experience 2 “Water cannot extinguish oil”

Target: Give an idea that burning oil cannot be extinguished with water.

Materials and equipment: a glass of vegetable oil, a glass of water, a fire extinguisher.

Progress of the experiment

The teacher pours water into a glass with burning oil until it is clearly visible that the oil is floating on the surface.

Conclusion: Experience shows that it is impossible to extinguish burning oil with water, since oil is lighter than water. It will float on top, continuing to burn. It is necessary to cover with a lid (to stop the access of air)

Experience 3 “Why does an explosion occur during a fire?”

Target : give an idea of ​​the cause of the explosion.

Materials and equipment : test tube, slice of raw potato, clamp, burner.

Progress of the experiment

The teacher pours some water into the test tube and plugs it with a potato stopper, heats the test tube over the flame. And suddenly - bang! – the cork noisily flies out of the cork. The steam pushed it out: the water began to boil, the steam became more and more, he felt cramped, he pushed the plug, and he escaped.

Conclusion: During a fire in an enclosed space, the air becomes very hot and expands. It becomes crowded, it breaks out, knocking out windows in houses.

Experience 4 "Fires pollute the air"

Target: show clearly how fire contaminates objects (soot).

Materials and equipment: candle, glass, porcelain cup, bowl of water, fire extinguisher.

Progress of the experiment

The teacher lights a candle, holds a glass over its flame, then a porcelain cup. These materials, which do not melt, do not catch fire, but heat up quickly. After some time, blackening will be visible on them (covered with soot). The teacher invites the children (when the materials have cooled) to touch the blackening with their fingers and make sure that it gets dirty.

Conclusion: experience shows that as a result of combustion, soot is formed, which pollutes the air and harms the health of living beings.

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

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

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


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

Ice soap bubbles

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

I'll give you a hint:

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

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

But in slow motion it’s just a fairy tale!

I'm complicating the question. Is it possible to repeat the experiment in the summer in order to get a similar option?

Choose answers:

  • Yes. But you need ice from the refrigerator.

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

Paper vs water

The real one is waiting for us experiment. Is it really possible for paper to defeat water? This is a challenge for everyone who plays Rock-Paper-Scissors!

What we need:

  • Paper;
  • Water in a glass.

Cover the glass. It would be good if its edges were a little damp, then the paper would stick. Carefully turn the glass over... The water does not leak!

Let's inflate balloons without breathing?

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

Ingredients:

  • Soda;
  • Plastic bottle;
  • Vinegar;
  • Ball.

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

Such a small experience can show even in kindergarten.

Rain from a cloud

We need:

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

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

author of the photo

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

Rainbow


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

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

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

Even easier is to use a disk and a flashlight.

Crystals


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

Can be grown from sugar

Lava jar

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

Eruption

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

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

A hole in the bag is not a problem

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

Water that doesn't spill


Only such water still needs to be produced.

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

"Slippery" egg

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

Snow in summer


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

Moving snakes

To make a moving figure we will need:

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

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

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

Battery train


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

Candle swing


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

Elephant tooth paste


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

Let's drink a candle


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

A real chameleon


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

Light up the rainbow

Place Skittles in a circle on a plate. Pour water inside the plate. Just wait a little and we get a rainbow!

Smoke rings

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

Multicolored liquid

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

Egg without shell

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

Dancing men

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

Decorating the ice


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

Launching paper rockets

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

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