Vulcan - experience (experiment). Children's experiments: Volcano made from soda and vinegar

Children are constantly interested in everything new. They are interested in the world, the structure of nature. They dream of seeing a tsunami, earthquake or volcanic eruption. They wonder where the mountains came from and why trees grow. You can’t explain or show everything, but you can offer your child an interesting activity together - making a homemade volcano with your own hands.

We bring to your attention several ways to create simple layouts. Any student can complete this project for a geography lesson independently. Younger kids will need your help, you can turn the construction of a volcano into a real one exciting game. It will be useful for preschoolers to take part in creating the layout. They will be able to learn how to work with plasticine, papier-mâché, plaster and any other materials that you choose to bring your project to life.

Before starting work, it will be interesting and useful for children to learn what a volcano is and what parts it consists of.

Volcano - mountainous formation, which appeared naturally over faults in earth's crust, through which lava comes to the surface. Lava is magma that has come to the surface and has gotten rid of its gases. Magma is the liquid, burning component of the earth's crust.

A volcano is most often represented as a high mountain, from the mouth of which steam pours out and lava bursts out. This is not entirely true, it can not only have the shape of a mountain, but also be very low, like a geyser or a small hill.

Pay attention to the cross-sectional diagram of the volcano. Hot magma rises through the crater to the surface, where it turns into lava, escaping through the crater. During an eruption, being nearby is extremely dangerous.

In our article, you will get acquainted with the creation of various volcano layouts. You can make a cutaway model. This kind of work will be good teaching aid for children.

How to make a volcano with your own hands

In this article you will learn how to create models from various materials, such as plasticine, paper, polyurethane foam, plaster. You will also learn how to turn your homemade volcano into an active one and will be able to demonstrate this phenomenon to children and friends.

Plasticine model

To create a volcano you will need:

• plasticine various colors: brown for the mountain, green for the grass and red to represent the lava;
• cardboard (will be a stand);
• base for a volcano, it can be a bottle or a paper cone.

Let's get started:

Creating a model from plasticine is one of the easiest ways. Even preschoolers can cope with this task.

Paper mockup

We make a model of a volcano out of paper. You can use newspapers, old leaflets, etc.

For the paper layout we will need:

Let's get started:

1. We cut off the neck of the bottle and attach it to the base (cardboard) with tape.
2. We make a frame. Attach one side of the cardboard strip to the top edge of the bottle, and the other to the base of the future volcano.
3. Once the frame is ready, begin to form the mountain. Crumple the paper into lumps and distribute it inside the frame.
4. When there is enough padding and the structure becomes dense, give it shape by wrapping it in clean sheets of paper.
5. Your work is almost finished! All that remains is to take the paints and beautifully design the resulting model.

In a similar way, you can make a model of a mountain out of paper. You just need to add a cone-shaped top, because mountains don’t have vents.

Have you accumulated a lot of unnecessary waste paper?

To make a papier-mâché volcano you will need:

Let's get started:

1. Cut off the neck of the bottle, cut whatman paper into equal long strips.
2. Glue the bottle to the cardboard. You can use glue or double-sided tape.
3. Make a frame using strips of whatman paper.
4. Then glue the same strips horizontally to make the frame more dense.
5. Tear newspapers and paper into pieces and soak in water or paste. Cover the frame with wet paper, coat it with glue, and sculpt the next layer. For strength, it is better to make 5 layers or more. Last layer make from pieces of white paper.
6. Let your layout dry. This design will take about a day to dry.
7. After the model has dried, it can be decorated with paints.

Vulcan in section from polyurethane foam and polystyrene foam

The cross-sectional layout will serve as a good teaching aid in geography. And creating such a model yourself is a fascinating process.

To make a cross-section of a volcano we will need:

From polystyrene foam we form the base and the volcano cone itself. We glue pieces of foam plastic onto the base in layers. Each layer should be narrower than the previous one.

When the base for the volcano is ready, polyurethane foam draw lava flowing out, let it harden.

After the foam has hardened, all you have to do is decorate the model and cover it with a layer of varnish.

Plaster model

A model of a volcano can be made from plaster. To do this you will need:

• gypsum;
• water;
• paints.

Let's get started:

1. Dilute the gypsum in water according to the instructions.
2. Form the body of a volcano from the resulting mass and leave the craft to dry.
3. After the plaster body has dried, paint it with paints.

Lava from dishwashing detergent and gouache

Let's get to the fun part about creating volcano models. Eruptions!

We offer you several options for making lava.

You will need:

• soda;
• dishwashing liquid;
• vinegar;
• red dye or paint.

Place a spoonful of baking soda in the mouth, add red dye or dye, and a couple of drops of dishwashing detergent.

Now, in order to arrange an eruption, it will be enough to pour table vinegar into the mouth.

Lava from sparklers

1. Crumble the sparkler into the crater.
2. Set it on fire.

Foam volcano made of potassium permanganate

You will need:

• potassium permanganate;
• hydrogen peroxide;
• liquid soap.

Pour liquid soap into the mouth, add potassium permanganate to it. To erupt, pour hydrogen peroxide into the resulting mixture.

Creating layouts is a fun activity. You have become familiar with the basic ways of creating models at home. It is not necessary to stop at volcanoes; you can start making models of attractions and architectural monuments, such as the Kremlin or Baiterek.

Plaster, paper and papier-mâché - universal materials, which will help you create interesting and beautiful fakes.

We have a new set for fans chemical experiments from the "Super Professor" series. This time we have to watch a volcanic eruption and pharaoh snakes.

Important! These experiments should only be carried out in nature - there is a lot of fire and ashes!

And about our experiments that we carried out at home, see the articles ““”.

This time we decided to start our chemical experiments by reviving pharaoh snakes.

Qiddycome: Series “Best Chemistry Experiences and Experiments: Pharaoh's Snake”

For this chemical experiment we needed:

• Evaporation bowl
• Dry fuel
• Matches
• Scissors (or tweezers)
• Calcium gluconate – 3 tablets
• Gloves

Conducting the chemical experiment “Pharaoh’s Snakes”

1. We put a tablet of dry fuel into the bowl and set it on fire.
2. Using tweezers, carefully place the calcium gluconate tablet on the fire.

The tablet turns into a Pharaoh's snake, which crawls out of the bowl and grows until it crumbles into ashes.

Calcium gluconate should be placed in the center of the burning tablet, then the pharaoh’s snakes will be fat :) We first put one calcium gluconate tablet in the center, and two at the edges, and in the video you can see how the snakes differ in size. Then we moved the calcium gluconate to the center and all the pharaoh's snakes began to flow merrily.

Watch the video of how Pharaoh's snakes crawl:

Scientific explanation of the Pharaoh's Serpents chemical experiment

When calcium gluconate decomposes, calcium oxide, carbon, carbon dioxide and also water. The volume of decomposition products is much larger than the volume of the original product, which is why such an interesting effect is obtained.

In the “Super Professor” set, the ingredients are designed to repeat the “Pharaoh’s Snakes” chemical experiment three times.

Qiddycome: Series “The best chemical experiences and experiments: Vulcan”

Like most blog moms, Olesya and I made a volcano out of soda and vinegar several times. I thought there would be something similar in the box. But I was very wrong. The eruption experiment here was completely different - much cooler!

For the Vulcan experiment we used:

• Evaporation bowl
• Foil (non-flammable heat-resistant material)
• Ammonium dichromate (20 g)
• Potassium permanganate (10 g)
• Glycerin – 5 drops
• Pipette
• Gloves

Carrying out the chemical experiment “Vulcan”

1. Place foil on the table and place the evaporation bowl on it.
2. Pour ammonium dichromate (half a jar) into the bowl and make a depression at the top of the slide.
3. Pour potassium permanganate into the recess.
4. Take a few drops of glycerin and drop it onto potassium permanganate.

A few minutes later our volcano caught fire. Myself! No burning!

Here is a video of our burning volcano:

Scientific explanation of the chemical experiment "Vulcan".

It turns out that ammonium dichromate burns on its own if you set it on fire. But in our experiment, a mixture of potassium permanganate and glycerin worked as a fuse. Due to the reaction of this mixture, heat began to be released, which led to the ignition of ammonium dichromate.

Burning volcano eruption - amazing chemical experiment ! We have probably never conducted a more interesting experiment!

DIY volcano model from salt dough. Master class with step by step photos.

Kushnareva Tatyana Nikolaevna - geography teacher, Secondary School No. 9, Azov, Rostov Region.
Target: Making a model of a volcano from salt dough using the testoplasty technique.
Tasks:
1. Contribute to the formation of a scientific picture of the world, an initial understanding of the types of volcanoes.
2. Develop children's creative research activity.
3. Cultivate interest in cognitive and research activities, determination, perseverance, and independence.

In my work, I invite you to find out whether it is possible to make a volcano at home and look at this dangerous, but it seems to me a very beautiful phenomenon - a volcanic eruption. Schoolchildren aged 10-13, as well as preschool children, can demonstrate their ability to create an artificial volcano.
Technique: Testoplasty, it seems to me, is very well suited for the implementation of my idea.
Purpose: Layout for research activities - experiment, as well as use as visual material to secure the external and internal structure volcano

"I spit fire and lava,
I am a dangerous giant
I am famous for my bad fame,
What is my name?" (Vulcan)

Volcanoes are geological formations on the surface of the Earth's crust or the crust of another planet, where magma comes to the surface, forming lava, volcanic gases, rocks (volcanic bombs) and pyroclastic flows.
Word "Volcano" comes from the name of the ancient Roman god of fire Vulcan. Translated from Latin - the god of fire and blacksmithing.

Probably, of all the possible natural disasters that threaten humans, volcanic eruptions are the most dramatic, if not in terms of the number of victims and destruction, then in the sense of horror and helplessness that engulfs people in the face of the raging elements generated by the fiery bowels of the planet.
The volcano is a fantastic sight. In a matter of minutes, it can devastate entire cities, kill thousands of people, destroy landscapes and even change the Earth's climate.
Scientists estimate that about 500 million people live near volcanoes today.
Since 1700, volcanic eruptions have killed more than 260,000 people. People will not be able to prevent mass deaths unless they learn to understand and respect volcanoes.
Externally, volcanoes differ from each other; the most common types of volcanoes are conical and shield. Shield volcanoes are wide, flat volcanoes ranging in diameter from a few kilometers to over 100 km, and are usually low and wide. The volcano was formed as a result of repeated outpourings of high-temperature liquid lava.
In this master class, I propose to make a conical volcano.
Conical volcano. The slopes of the volcano are steep - the lava is thick, viscous, and cools quite quickly. The mountain has the shape of a cone.

Materials:
Colored paper;
PVA glue";
Vinegar;
Soda;
Scissors;
Flour;
Gouache paints;
Brush;
Sheet of cardboard;
Glass cup.

Step by step description work

1. First we need to cook salty dough for making the Vulcan Model. To prepare salt dough, we need 400 g. flour, 200 gr. fine salt and 150 ml. water.

2. The dough is ready, you can start working.

3. To make the base of the Layout, we need to prepare a square of green colored paper 20/20 cm and a sheet of cardboard 20/20 cm

4. Apply PVA glue to the cardboard

5. The base of the Vulcan Model is ready

6. Place the dough on the base, make a hole in the center and place a glass cup in it, which will act as a muzzle.

7. Shape the Layout. We need a day for the dough to dry. You can speed up the drying process by placing the mock-up in the oven for 20 minutes, alternating sides.

8. Let’s start painting the layout, using gouache paints. Apply paint layer by layer. We cover the lower part of the slope with green color.

9.Add a few light colors green paint.

10. Cover the middle and upper part of the slope of the model with brown paint.

11. It is necessary to let the paint dry before applying flowing lava to the Vulcan model using red gouache.

12. The Vulcan model is ready for the experiment

13. For experimental activities, we will need vinegar and soda tinted with red gouache in a small amount.

14. We pour soda into the mouth of the model, and then pour in tinted vinegar. Volcanism begins!

15. We observe how lava flows down the slope.

In the course of research activities, it was confirmed that it is possible to create an artificial volcano through experimental activities.

Volcanoes began to "volcano" -
Spew lava from the crater.
Lava flowed down the slopes
And it burned the Earth badly. (Elena Romankevich)
Thanks everyone for your attention!

All children are inquisitive, many of them are interested in a variety of natural phenomena. Any child wants to know what a tsunami, tornado or all of these look like can be used as ideas for creativity and homeschooling. How to make a real volcano at home? It’s not at all difficult to build an eruption model with your own hands from scrap materials.

Volcanoes - what are they?

Recall that under the solid crust there is magma - molten rock that can harden, seep to the surface through thin cracks or erupt through large holes. In the latter case we are talking about volcanoes. Most often these are mountains located at the junctions of continental plates. But sometimes volcanoes can appear in a relatively short period of time in areas with almost flat terrain. Most often, mountains spewing lava are depicted as quite high and having correct form. But in fact, volcanoes can be different, including low ones, which can visually resemble small hills. At the time of the eruption, magma and gases under significant pressure come to the surface of the earth. Explosions often occur at this moment, and some volcanoes gush with hot lava like geysers.

We make a blank for the “fire mountain” with our own hands

"How to make a model of a volcano at home?" - a popular question from parents who decide to spend something interesting with their children creative activity. To make this craft you will need: cardboard or plastic bottle, paper or gypsum plaster, paints and some auxiliary tools, which can be found in every home.

Prepare some kind of base for creating a craft. This could be a piece of plastic, such as a lid from a food tray, or another dense material - plywood, cardboard. Cut off the top of the bottle, this will be the volcano, respectively, and leave the height for it at your discretion. Alternative option- make a base from a cardboard cone of a suitable size. Attention: if your volcano is an active model that will erupt more than once, the base should be a sealed container. Glue the cut part of the bottle tightly onto plastic base using waterproof glue or sealant. You can cut off the bottom and top of the container and insert them into each other.

Volcano decor

The workpiece should be some kind of cone or cylinder with a narrow top on a stand. As soon as this structure is dry, it’s time to start decorating it. To decorate the slopes of the mountain, take decorative plaster or prepare paper pulp from which you can create papier-mâché. In the second case, it is better to take white napkins, paper towels or toilet paper. Grind the raw materials, after wetting them, using a mixer and add a little PVA glue. In this case, the mass will be homogeneous and easy to apply.

How to make a volcano model with your own hands from an existing blank? Everything is very simple. Cover a cardboard cone or piece plastic bottle chosen sculptural material. Form something like a mountain - with an expansion at the foot and a sharp top. Be sure to leave a crater hole at the top. Your volcano will look much more interesting if you make the surface ribbed, covered with a network of channels through which lava will flow picturesquely. When the modeling is completed, dry the workpiece thoroughly. After this, you can start coloring it. If you use non-waterproof paints, you can additionally coat the craft with a clear varnish. That's all - the volcano (model) is ready, if you wish, work on the surrounding landscape. If the size of the stand allows, make trees, draw grass or sand, you can add figures of people and animals.

A simple version of plasticine crafts

If the method described above for making a homemade “fire mountain” seems too labor-intensive to you, try making it using a simpler technique. A small volcano can be made from plasticine. Take brown modeling material or mix all the blocks in the set until you get a uniform “dirty” shade. Make a cone with a hole on top, mark the relief if desired. If your volcano is an active model and is being made to “erupt,” glue it to a modeling board or plastic panel/tray from food packaging. Try to make the connection airtight. Additionally, you can decorate the craft with red plasticine, depicting frozen lava on the slopes of the mountain.

The eruption begins!

Most often, a “volcano” is made to carry out a home “eruption”. Do not be afraid, this experiment completely safe. Take a small amount of baking soda, a dye of a suitable shade and a drop of dishwashing detergent (you can replace it with a couple of pinches washing powder). Mix all the ingredients and place them inside the mountain (take care of a special recess in advance). In order for hot lava with foam to begin to rise from the crater of a volcano, you just need to drop just a little vinegar inside. Such interesting experiment will amaze kids and surprise schoolchildren. The model will help not only interest children, but also tell them in an interesting way about the interaction of soda and vinegar.

Fun or entertaining chemistry?

Making such crafts even with the youngest children should be combined with learning. Tell us about volcanoes and their formation, bring interesting historical facts. Such homework will probably be remembered better than subsequent chemistry lessons. When conducting an “eruption”, also try to explain that with the help of home we are only imitating the real a natural phenomenon. The reaction itself deserves special consideration. Invite your child to think and describe the interaction of two substances. It is also useful to draw a conclusion with a chemical explanation of the experiment.

Sectional model of a volcano: how to make it?

In addition to making crafts depicting general form Fire Mountain, it’s not at all difficult to make another educational layout at home. We are talking about a cross-sectional model of a volcano - respectively, half of it with a demonstration inner layers. What is the mountain that spews out lava and ash made of? A volcano is a collection of different rocks; accordingly, layers can be made in different colors: from yellow to dark brown. Do not forget to mark the crater at the top and from it to the very bottom, lay a channel through which the lava rises. It is most convenient to make such a model of a volcano from plasticine. Your layout can be three-dimensional (a mountain cut in half) or flat. Use materials of different colors and combine layers in correct sequence. If you're doing a flat layout, you can additionally show how magma rises to the earth's crust and finds its way to the surface through a volcano crater.

Every day your children strive to learn something new. And it is parents who must not only support this desire, but also help their kids in every possible way in studying this big and such interesting world. The task of adults is not just to tell and show as many new things as possible, but also to teach the child to think and draw conclusions. And practical research will help with this.

Today, modern stores offer many options for different sets for chemical and physical experiments, but you don’t have to spend a lot of money to show your child real miracles. For example, you can arrange a real volcanic eruption for your child right at home using ordinary baking soda and vinegar, or show your baby how to fill a balloon with gas without inflating it.

How it works?

Both experiments are based on a neutralization reaction, since vinegar and soda, which are essentially an acid and alkali, neutralize each other, releasing carbon dioxide - our “lava”. It will be very interesting for your child to look at a phenomenon that has never been seen before. And an older child will be interested in learning more about carbon dioxide. We exhale that gas into the air, and plants can process carbon dioxide, producing oxygen. With its help, those same bubbles are formed in the soda.

How to inflate a balloon without hands?

What will you need for the experience?

How to conduct an experiment?

Prepare all materials and place them at an accessible distance. A solution of soda and water should be poured into glass bottle. Then pour vinegar into the bottle and quickly put it on the neck of the bottle balloon. It is important to secure the ball well on the neck with tape so that the ball does not rip off. Almost immediately you will notice how carbon dioxide fills the balloon, inflating it.

Experience a volcano eruption right at home

What will you need?

How to conduct an experiment?

Using plasticine we stick it around plastic dishes(cylinder of soap bubbles, for example) and securely attach it to the plate. For greater plausibility, you can give the vessel the shape of a real volcano, with protrusions and irregularities. Pour soda into the flask, pour vinegar on top and watch a real eruption!
