You can watch a volcano erupt at home not only on TV. With the help of a small chemical experiment, you will arrange a real eruption on a fabulous island.

From this article you will learn

All that is needed

For the experience, you will need some household chemicals and decorative items to create an island. The volcano island can be made from natural materials or you can use dinosaur sensory box sets.

Model of the volcano is molded from plasticine. The creation of a fabulous volcanic island for the experience is the main part of it and serves to develop the child's imagination and creativity. Such activities will help instill a love of chemistry and geography. Fine motor skills of the fingers, the child will develop during the manufacture of plasticine terrain and its inhabitants.

To make an island you need:

• cardboard;
• stapler or narrow tape;
• box with colored plasticine;
• small animal toys;
• multi-colored pebbles;
• a large plastic box or bowl in which the island will stand;
• glass or plastic container with a volume of 200 ml for the vent of the volcano.

For the experiment you will need:

• soda 20 g;
• food coloring:
• vinegar 9%;
• dish detergent 25 ml;
• water 100 ml.

Usually the experience happens until mom runs out of all the baking soda and all the vinegar, so please be patient.

Children cannot conduct experiments on their own without adults. If vinegar gets into the eyes or mouth of a child, a burn of the mucous membranes may occur, and if swallowed, a burn of the esophagus.

Making a fabulous island

You can build an island in a large plastic container. Pour real water, lay out the bottom with round pebbles. Make a container for a volcano from a jar of baby food or an old glass. For the mountain, inside which the container will stand, you need to make a cardboard layout, his child will be happy to cover it with plasticine.

The sequence of making a volcanic mountain:

• cut out a circle of the desired diameter from thick cardboard;
• make an incision from the edge to the center of the circle;
• roll up the cone;
• the edges of the cone are fastened with a stapler or tape;
• cut off the upper part of the cone at a height equal to the capacity chosen for the volcano;
• place the container inside the cone.

From above, I coat the mountain with plasticine. To do this, roll out small brown plasticine cakes and stick to a paper cone, completely covering the cardboard. The top of the volcano can be made of red plasticine, which will imitate red-hot lava.

They set up a volcanic mountain on a dry island of pebbles. They sit around small rubber animals that are among children's toys. Colorful amazing dinosaurs or wolves, foxes, bunnies, bears and other inhabitants of the forest and jungle. Depending on which animals were planted, vegetation is selected for the island. Large tree ferns and horsetails for dinosaurs, and ordinary Christmas trees and birches for bunnies and foxes.

Plastic plants are also often sold in children's play sets. You can use a leaf of a live fern and twigs of plants if it's summer outside. Plants can also be molded from plasticine, made from threads and beads or ordinary cardboard.

You can make small houses out of cardboard for plastic Indians and soldiers. It is better to use cardboard for making plants and houses when the island is in a container with blue-colored sand instead of water or on a blue plasticine sea.

Conducting an experiment

Finally the island is ready. All toy animals and people froze in anticipation of an interesting event - a volcanic eruption. They know that the volcano is not real and therefore they are not afraid of it.

To conduct the experiment, pour a tablespoon of soda into the jar-vent of the volcano. Add a tablespoon of dish detergent. Red or orange food coloring is dissolved in 100 milligrams of water and poured into soda and detergent. The basis for the experiment is ready, it remains to add vinegar. Mom, you can let the child pour vinegar into the volcano on his own, under her supervision, so that he does not do it in her absence. It is better to repeat the experiment for an encore, pouring vinegar into the “vent” of the volcano and pouring soda into it, while the child is interested and asks to repeat the experiment.

When vinegar is added, the soda will begin to foam, erupting from the "vent of the volcano" like red or orange lava. The detergent will allow the “lava” to foam longer and more abundantly, overflowing from the vent and flooding the surroundings along with plants and animals that were inadvertently placed too close.

Afterword

The safest way to do a volcano experiment for young children is with baking soda and vinegar. It can be repeated many times, and getting the necessary materials for the experiment is not difficult.

The most interesting thing in the experience is the creation of your own fairy-tale island with the child, which can be used not only for the Volcano chemical experiment, but also for an exciting game.

With older children, you can conduct the Volcano experiment at home using
, potassium permanganate and glycerin. For the experiment, ammonium dichromate is poured into an evaporating bowl in the form of a slide, in the middle of which a depression is made. Add a little potassium permanganate and a few drops of glycerin to the recess.

After a few minutes, due to the interaction of potassium permanganate and glycerol, ammonium dichromate will ignite. Sparks will be thrown from the volcano in all directions, and a fountain of fire will begin to erupt. Before starting the experiment, the bowl must be placed on the foil so as not to burn the surface on which the experiment will take place.

Ammonium dichromate can simply be set on fire, and it will burn like a volcano, spewing sparks. The experience is exciting, but without the presence of adults, children should not be allowed to do it. Burns can be caused not only by sparks, but also by the chemicals used.

Good luck with your experiments!

September 22, 2010, 13:42 Excuse me, they’ve gone crazy – what’s so live science about it? Just like brainbreakers on discovery

It seems that quite a lot of interesting ideas are proposed in the next section.

I would also mix cola with mentos

Then vinegar + soda will not work, because we get expansion due to gas, and as a result, foam.

To get around this, I see 3 options:

1. Use another substance that expands strongly without creating a gas (I don't know one).

2. Use non-chemical force to erupt. For example, communicating vessels, we raise one, erupt from the other. Or pump up pressure with a bicycle pump (instead of soda / vinegar in the apparatus from paragraph 3, replace the neck with a nipple)

3. Or leave the gas, but separate the mixture (but then you need a non-trivial device for the volcano), for example, pour condensed milk, dip a straw into it, and start the reaction from above.

For example on this setup:
http://img638.imageshack.us/img638/3518/volcano.gif
where:
1 - condensed milk
2 - soda
3 - neck for pouring vinegar (hermetically sealed)
4 - a straw from which there will be an eruption (the edges of the straw with the neck of the volcano also need to be sealed).

September 22, 2010, 23:35

By the way... to rehabilitate the scientific nature of the article, I will give the interaction reaction on which the experience is based:

Vinegar (acetic acid): CH 3 COOH
Soda (sodium carbonate): Na 2 CO 3

When mixed we get:
Na 2 CO 3 + 2 CH 3 COOH =
2 CH 3 COONa + H 2 CO 3

CH 3 COONa - sodium acetate (sodium salt of acetic acid)

H 2 CO 3 - carbonic acid. Which quickly breaks down into CO 2 (carbon dioxide) + H 2 O (water)

Carbon dioxide is much larger in volume than the original substances. Due to him, and there is an expansion with an ejection "over the edge".

September 23, 2010, 17:57

I will try to give an answer to my homework myself (at the level of a hypothesis, though):

It is known that freshly kneaded dough "rises" well while standing warm. The mechanism is the formation of carbon dioxide bubbles throughout the dough. Since they do not have the opportunity to go outside, they lead to swelling of the test.

Now we do the following: we prepare the semi-liquid dough in a cold state, place it inside the volcano and begin to actively heat it up. In theory, a strong swelling should begin with the outflow of a real semi-liquid "lava".

September 28, 2010, 00:19

It won't work with the test.
It will need to be heated very strongly, which will lead to a firebrand, because there is not much gas there. And it is unrealistic to accelerate gas formation.

You will need a larger container and make it buoyant so that it is lighter than bubbling water (only foam crumb comes to mind), but you will need to experiment with the ratio of water to foam ... and lava plasticity will be difficult to achieve ...

Here is one of the volcanoes.
Volcano Lemery
The French chemist, pharmacist and physician Nicolas Lemery (1645–1715) also observed something similar to a volcano when, having mixed 2 g of iron filings and 2 g of powdered sulfur in an iron cup, he touched it with a hot glass rod. After some time, black particles began to fly out of the prepared mixture, and the mixture itself, having greatly increased in volume, warmed up so much that it began to glow. Lemery Volcano is the result of a simple chemical reaction between iron and sulfur to form iron sulfide. This reaction proceeds very vigorously and is accompanied by significant heat release.

A lot has already been written about the use of baking soda in one area or another. The properties of this substance make it possible to use it in the kitchen when cooking, at home for cleaning various surfaces from grease and plaque, in the treatment of various diseases, and so on. Another use of sodium bicarbonate is the ability to arrange educational performances for children, for example, you can make your own volcano out of soda.

Stock up on baking soda and vinegar because your kids will be asking you to do it again and again!

This is possible due to the ability of soda to react violently with certain substances, such as vinegar. And one of the most common experiences associated with this property of sodium bicarbonate is the demonstration of a volcanic eruption. Below is a detailed look at how to make a baking soda volcano.

Experience "volcanic eruption"

The first thing you need to know is why such a reaction occurs when soda and vinegar are combined. Without going into details: soda has pronounced alkaline properties, while vinegar, on the contrary, is acidic. When their molecules are combined, both media are neutralized to neutral, as a result of which carbon dioxide is released, the rapid release of which causes the appearance of foam.

Experience with the combination of these substances can be used not only as a demonstration of a natural phenomenon. This is a good moment to explain the basics of the interaction of various substances and the reactions between them.

Preparation for the experiment begins with the manufacture of the volcano itself. This can be done in several ways, which will result in a reusable inventory or, accordingly, a disposable inventory. To create the first, you will have to make more efforts and time, while the second is suitable for a spontaneous decision to please children with an interesting spectacle.

Method number 1

In this case, just a reusable model is created for repeated execution of the experiment.

To make the body of the "volcano" you need the following components:

• an ordinary plastic bottle for any drink with a volume of 1.5 liters;
• a flat plastic lid (for example, from disposable food containers);
• adhesive tape of any kind;

It is not necessary to sculpt a "volcano" from a new plasticine, an already used one is quite suitable

• gypsum or alabaster (can be replaced with salt dough);
• gouache with PVA glue, in a ratio of 1: 1 (replacement with acrylic paint is possible);
• cutting tray or cutting board (as a base);
• paper;
• foil.

Sequencing:

1. Building the foundation. The plastic bottle must be cut by measuring the desired height of the cone (you need the upper part). The resulting base is carefully attached to the above plastic cover with tape.
2. Attaching the base of the volcano to the base. The resulting design is attached with adhesive tape to a tray or cutting board. You can also use a suitable piece of plywood or a thin board as a base.
3. Cone formation. With the help of pieces of paper and adhesive tape, a cone is formed around the bottle with an upper base at the edges of the neck. To avoid subsequent soaking of the paper pulp, the cone is wrapped in foil.
4. Finishing the "walls" of the volcano. Dilute gypsum or alabaster to a state of thick sour cream. The resulting mixture covers the slopes of the "fire-breathing mountain". With the help of a toothpick or a fork, the relief of the "mountain slopes" and the troughs are formed for the preferred movement of the "lava".
5. Final finishing. After the "slopes" have completely dried, they should be painted with gouache mixed with PVA. It's best to use brown and black paint and paint the "lava" chutes a little red.

After preparing the "volcano" it is necessary to deal with the "lava". It, of course, must be prepared immediately before the demonstration of the "eruption". The components in this case are:

• baking soda - 10 gr;
• dishwashing detergent - 2 drops;
• gouache or red food coloring;
• vinegar - 10-15 ml.

This number of ingredients is indicated for the minimum amount of "lava" and low "volcano". If it is necessary to increase the intensity of the "eruption", the number of all components increases accordingly. The sequence of actions in this case is as follows:

1. Mix the baking soda, the chosen type of dye and dishwashing detergent, mixing thoroughly.
2. Pour the resulting mixture into the "crater of the volcano".
3. Add vinegar carefully to the "vent" and enjoy the result.

For a more active reaction, vinegar can be poured quickly. By the way, the added dishwashing detergent is responsible for this.

Method number 2

As mentioned above, a volcano made according to the previous method makes it possible to obtain props that can be used repeatedly. However, this takes a significant amount of time. For a single use, you can make props using a simplified method.

The spectacle is really spectacular

In this case, the ingredients will be:

• a sheet of cardboard;
• plasticine;
• small jar;
• tray or cutting board (as a base).

The sequence of actions is as follows:

1. Fold the cardboard into a cone, giving the required angle of "slopes". Glue it in this position or secure with tape. Cut off the top to get a "vent".
2. The outer part of the cardboard is covered with plasticine, with the formation of "ledges" and "gutters".
3. Before the demonstration of the experiment, the jar is filled with a mixture of soda, dishwashing detergent and dye, after which it is placed on the base and covered with a “mountain” cone.
4. Next, vinegar is poured into the vent and the "eruption" begins.

It is possible to conduct an experiment with citric acid or lemon juice. In this case, vinegar is not used, and soda should be poured last.

The properties of baking soda allow this product to be used in a variety of situations. And as all of the above shows, even as a means of entertainment or to expand the horizons of children. Thanks to the simple preparation and the property of soda to enter into a violent reaction with vinegar, you can give your children an unforgettable spectacle, which they will ask for pleasure more than once.

The backs straighten
Friend, friend, smile! (Children smile at each other, friend)
Educator: Guys, have you noticed that guests have come to us today?
Children: Yes!
Educator: And let's first say hello to the guests, and then share our good mood and our smiles. And send our smiles with an air kiss! Well done!
Surprise moment. There is a puddle on the floor.
Educator: Oh, guys, what is this puddle on our floor?
Assumptions of the guys. At this time, sobs are heard and the Luntik toy appears.
Educator: And so you shed your tears here? What happened to you?
Luntik: My grandfather Shershulya gave me a very interesting riddle, but I still can’t solve it. So I got upset. Can you help me solve it?
Educator: Let's help Luntik solve the riddle?
Children: Yes, of course!
Luntik makes a riddle.
I am a terrible black giant,
What should I do - I decide for myself
Can I sleep, can I growl
Spew fire and ashes
Well, try to guess
What is my name?
Children: We know! It's a volcano!
Luntik: Guys, what good fellows you are! And what is this - a volcano?
Educator: Now I will tell you all and show you the legend about the ancient god Vulcan. Listen and look attentively (showing a presentation)
Slide #1.There lived a god named Vulcan. He liked blacksmithing: standing at the anvil, hitting iron with a heavy hammer, fanning the fire in the furnace.
Slide #2.He built himself a forge inside a tall mountain. The mountain was right in the middle of the sea. When the volcano worked, the mountain trembled from top to bottom, and the roar and rumble carried far around. Hot stones, fire and ashes flew from the hole on the top of the mountain with a deafening roar. “The volcano is working,” people said with fear and went to live away from the mountain, so that their homes would not be burned by fire, their gardens and fields would not be covered with ashes. Since then, they say that all fire-breathing mountains began to be called volcanoes.
Slide number 3. Guys, what do you think a volcano looks like? Look at our volcano. (In the presentation and on the layout of the volcano)
Children: On a triangle, a cone.
Educator: Right! What does a volcano erupt?
Children: The volcano spews hot lava, ash, stones.
Slide number 4. Look at our volcano and tell me what the top of the volcano looks like? Maybe Luntik will tell us?
Luntik: The upper part looks like a big hole, a funnel.
Educator: That's right, well done, and it is called the crater of a volcano.
Educator: That's right, the volcano looks like an ordinary mountain, but inside it there is a very hot liquid - magma.
Slide #5 The volcano is considered dormant while the magma lives in its house.
Slide #6. And if a volcano erupts magma, then it is an active volcano.
Guys, now let's tell you and show Luntik how the volcano erupts.
Dynamic pause.
Children squat with their hands up in the form of a cone.
1. Volcanoes started to play
Spew lava from the vent (they begin to rise on their toes, hands up, stretch, shake with brushes, lower down).
2. The volcano is booming! The volcano is puffing!
How ugly he looks now! (hands on the belt, raise them up, clench and unclench fists, stomp your feet).
3. But now he began to get tired,
The fire in it began to fade (we slowly lower our hands with a squat).
4. The last time I breathed fire (sitting a long exhale).
5. And fell asleep for decades! (hands under the cheek, the volcano falls asleep).
Educator: Guys, do you want to wake up the volcano yourself?
Children: Yes, very much!
Teacher: Well then
Get up quickly and smile!
Higher, higher stretched!
Right, left turn! And we run faster forward!
Educator: So we ran to the laboratory. In the laboratory, everything is ready for experiments. Let's see how our volcano will spew lava. But first, let's remember the rules of conduct in our laboratory.
Rules! (Safety signs are made in advance) Now I will put on special protective clothing (robe, cap, gloves).
Educator: Well done!
(Conducting an experiment).
Educator: Luntik and you sit next to us. Let's take a close look at the diagram and do everything exactly as indicated in it! Let's put our "volcano" on the tray. Let's look at the diagram, what do we take first? That's right, 2 tablespoons of soda, pour them into a glass of water. Mix well! A large spoonful of red paint, mix again. Add 1 spoon of washing liquid. Mix. Let's take a watering can, insert it into the mouth of our volcano. Have you got a crater? Well done, right! And now, attention, we are doing everything 2 steps back! our volcano! What are you observing?
Children: The volcano began to erupt.
Educator: And what does he erupt?
Children: Lava!
Educator: Well done! Now you and Luntik have learned what a volcano is and how it erupts! And now let's get back to our chairs, I'll tell you something else about volcanoes.
Slide number 7.Guys, there are a lot of volcanoes on the territory of our country!
Slide #8.The largest volcano is located in Kamchatka, it is called Klyuchevskaya Sopka. Look at him! How big he is!
Slide number 9.Look how beautiful it is at night! A very bewitching sight! But do not forget that it is also very dangerous!
Luntik: Thank you very much! In gratitude to you, I treat you to my favorite strawberry pies that my grandmother baked! Bon appetit! And I will run and tell all my friends about volcanoes! Goodbye!
Educator: Children, did you like our lesson? What did you like the most? (Answers of children). And now let's draw how the volcano erupts! And we will place the most interesting drawings in our daddy “Young
researchers."

We make a blank for the Volcano experience

Experience at home Volcano

Now I will tell you in detail how to make the volcano experience. By the way, during the experiment, the children took an active part - they covered the paper cone with plasticine, poured soda into a jar, poured detergent, dyed the water with paints, after which the resulting colored solution was poured into a jar. The only thing I did myself was to cut out the cone, fasten it with a stapler and pour vinegar into the mouth of the volcano, after which the eruption began. So, we proceed directly to the experiment.
