The proposed model of the volcano is easy to make at home. It can become a spectacular imitation of the process that takes place in the bowels of our Earth. Manufacturing of the object is divided into 2 logical parts. The first part is making a volcanic cone. The second part is actually a demonstration of the process of magma eruption.

1. Making a volcanic cone

To make a cone model, you will need:
1. Plastic bottle.
2. Plasticine.
3. Scissors.
4. Any building mixture - gypsum, putty, dry tile adhesive, ready-made plaster mixtures.

First of all, we cut off from plastic bottle the upper third.

We discard the lower part - we will no longer need it. With the upper third left nail scissors carefully cut off the neck with a small plastic gap - it will play the role of the crater of our future volcano.

Cover the cut plastic cone with plasticine, modeling the shape of the future volcano.

On it we apply, mixed with water, any building mixture.

The photo shows a mixture of tile adhesive and acrylic putty, but gypsum, cement or ready-made dry plaster will work.

In the cone, densely and picturesquely coated with putty, insert the inverted top of the bottle with a tightly closed lid.

In order for the mass to harden, dry out and get stronger, we leave the potential volcano for several hours in a dry place.

2. Demonstration of a volcanic eruption

To simulate a volcanic eruption, we need soda, 100 ml of vinegar and red watercolor paint.

With a brush, wash the watercolor paint into a glass with vinegar.

The more dye there is, the more spectacular the eruption will be.
It is better to put the cone in a dish or bowl so that our "lava" does not stain the table, and pour 2 teaspoons of soda into a conventional crater.

After that, slowly pour the colored vinegar into the soda crater.

If you did not mix up or regret the components, then you will witness a unique spectacle - the eruption of a home-made man-made volcano.

Such an elementary chemical-geographical experiment can be demonstrated to your own children who are going through a period of fascination with the history and nature of the Earth. Such a number looks no less impressive in the lessons at school - in the 6th grade, in the process of studying the topic "Lithosphere".

Do-it-yourself volcano - good fun both for an adult and for a child. The main thing in business is not to hesitate to use your imagination. A volcano can be made from styrofoam, papier-mâché, plasticine, earth, or clay. It is very important to give a similarity to the real territory on which the volcano is located. This can be done by adding small details: different animals running away from danger, miniature copies of people, trees, bushes, grass. It is necessary to breathe life into the big picture, which will undoubtedly refresh the process of magma eruption. By adding dyes to the soda, the lava coming out of the vent will be much more effective.

How to make a volcano at home from styrofoam

In order to make a beautiful erupting volcano at home, in addition to ingenuity, you will need desire and some materials.

Materials for work

• Large glass bottle - 1 piece.
• Polyfoam white, density No. 25. Dimensions: 35 cm high, 40 cm wide, 40 cm long.
• Glue "Dragon".
• Primer ST-16.
• The tassel is wide.
• Sandpaper of various grain sizes.
• Starting putty.
• Small rubber spatula.
• Primer for putty.
• Layout with a new blade.
• Water-based paints.
• Water-soluble varnish.
• The paint brushes are wide and narrow.
• Fiberboard - size 60 cm by 60 cm.
• Plasticine of different colors.

The working process

• A piece of polystyrene must be carefully divided into two halves - 17.5 cm / 20 cm / 20 cm. It can be cut with a saw for metal, so as not to severely injure the surface.
• After the foam is split in two, you need to cut out the middle of the foam to hold the glass bottle. The neck of the bottle should be hidden under the top of the styrofoam. After the bottle is placed in polystyrene, the halves are glued together with Dragon glue. The bottle should come out through the bottom of the makeshift volcano.
• Further mock-up the extra pieces of foam are cut from the outside in order to shape the volcano.
• After the foam has already become like a volcano, you can crumble fine foam fraction and do sanding surface with sandpaper. First large, then smaller.
• The time has come for priming the surface (2 layers). Each layer is applied after the previous one has dried. Layers will prevent the putty from crumbling.
• Ready putty is applied with a spatula. The next layer lays down after the previous one has dried. The putty should not crack, the thicker the layer, the more likely it is to crack. When using a flexible filler, the surface will be more resistant to movement.
• If all layers of putty are dry, the surface is sanded with medium and fine sandpaper. This is done in such a way as not to remove curves and waves. The volcano should still look like a volcano.
• Apply a primer with a brush to strengthen the putty (several layers).
• Now you can prepare the paints that will be used to paint the surface of the volcano. Colors, for example, blue with green, lilac and orange.
• Water-based paint is selected for quick drying. Gouache is also used.
• When the volcano is painted, varnish is applied. Now the surface is glossy and shimmers pleasantly. Instead of water-soluble varnish, the product is varnished with alkyd varnish. The surface will be stronger and more reusable.
• A fiberboard site for the volcano is being prepared. The area around the active volcano is inhabited by hand-made plasticine animals. Trees are planted, real or plasticine stones are placed.
• Now you can start activating your home volcanic brainchild.

How to make a volcano at home - lava

The following materials are used for lava:

• bicarbonate of soda - 4 tablespoons;
• vinegar - 1 glass;
• red dye.

Cooking process:

• Through the funnel into glass bottle poured soda and dye to give color.
• The bottle is placed through the bottom into the center of the volcano.
• The volcano is installed on the site.
• The next step will be launch. The vinegar is poured through a funnel. An eruption occurs!

The model of the volcano is made in such sizes that fantasy can allow. A volcano can be low or high, the territory in which it is located is not necessarily square. For example, building tools can easily shape a circle. The colors are very different. If desired, it is very easy to make an impressive background from fiberboard, which depicts the sunset, birds flying away in panic or even pteranodons.

Children are curious and want to know many things. They are interested in various natural phenomena: hurricane, tsunami, volcanic eruption. These phenomena are simulated at home with a strong desire. Making a volcano at home with your own hands is a completely feasible task for everyone. The experience will require a minimum of available materials, patience and time.

Underground is magma - molten rock that seeps to the surface through small holes in the ground or erupts through craters. Volcanoes are located on the border of tectonic plates in the mountains. But there are cases of their appearance on the territory with a flat relief and for a short period of time. Active volcanoes are mostly depicted as huge and having the correct shape, but this is not so, in fact, there are different types. Volcanoes can be high or very small and disproportionate.

The eruption proceeds as follows: gases and magma that are underground are pushed upward under strong pressure. Sometimes there are even explosions, sometimes volcanoes spew lava, gushing like geysers.

Salty dough volcano

The experience requires a minimum of materials and a little patience. To make a model of a volcano with your own hands, you will need:

After finding everything you need, we start modeling. Let's get to work, following the instructions:

From baking soda

To make a product, you will need: water, vinegar, diluted food colors, dish detergent, baking soda.

Procedure for creating a volcano:

Plasticine and paper

It will be even faster to model a volcano from paper and plasticine. First, let's make the shape of the product. Take a piece of cardboard, roll it up to make a cone, and cut off the top of the resulting cone. The model of the volcano is made at home.

Now stick the resulting model with plasticine on top, you should get a mountain. Place the mockup on a tray or platter. Put a mixture of lava (food coloring, paint, soda) into the jar and place the jar inside the craft. The homemade volcano is ready. Such a product can be made quickly, easily and inexpensively.

Reusable craft

This option is very convenient, because you can return to the created volcano again and again. To create crafts you will need:

For the eruption, you will need: vinegar, a little soda, red food coloring, a little dishwashing detergent.

Now the most interesting stage has come. Place a little baking soda inside the vent, add a little dishwashing liquid and add red food coloring. Pour in a little water if required. Add some vinegar to the mouth of the volcano, and the eruption begins!

Big Bang

Children will especially like this vapiant. To simulate a big bang, you need the following:

Using liquid nitrogen

A bit dangerous, but no less interesting way... An even larger spectacle will turn out if you do the following:

When creating a woodcan at home, use your imagination. Here are some tips:

• Color the product if desired.
• Add ingredients carefully so that nothing gets dirty.
• Add mints and soda to enhance the eruption.
• Be sure to wear glasses and gloves.

As you can see, making a volcano at home is simple and fun. The product will give an unforgettable experience for both children and adults. Making a volcano can be combined with a geography or chemistry lesson for children, and adults just have a good time doing this.

Attention, only TODAY!

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

Today, modern stores offer many options for different kits for chemical and physical experiments, but it is not at all necessary to spend a lot of money to show your baby 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 acid and alkali, neutralize each other, while releasing carbon dioxide- our "lava". It will be very interesting for the kid to look at a phenomenon that has never been seen before. An older child will be interested in learning more about carbon dioxide. We breathe that gas into the air, and plants are able to process carbon dioxide, producing oxygen. With its help, the very bubbles are formed in soda.

How to inflate a balloon without hands?

What is needed for the experience?

How do you run an experiment?

Prepare all materials and place at an accessible distance. A solution of soda and water must be poured into a glass bottle. Then pour vinegar into the bottle and quickly put a balloon on the neck of the bottle. It is important to fix 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 volcanic eruption right in your home

What do you need?

How do you run an experiment?

Using plasticine, we stick around plastic dishes (cylinder from under soap bubbles, for example) and securely fasten to the plate. For greater believability, you can give the vessel the shape of a real volcano, with protrusions and irregularities. We fall asleep in a flask with soda, and pour vinegar on top and observe a real eruption!

How can a child be able to tell about what a volcano is in an accessible and interesting way? You can, of course, arm yourself with books with pictures of the volcano in a section and try to explain in words how the magma is thrown out. Or you can make a volcano yourself at home. You will not only satisfy the curiosity of the young researcher, but also awaken interest in various sciences: geography, chemistry and geology.

Making a volcano at home is very easy. Simple products to find at home and uncomplicated detergents allow you to create beautiful effects. It is recommended to conduct similar experiments with children six to seven years old: at this age they will be able to better understand the essence of the action taking place. Although such a spectacular show will be interesting for both the kid and the adult.

The purpose of the experiment- to form in children an elementary idea of ​​the natural phenomenon "volcano", to clearly show the interaction of alkali with acid (neutralization reaction).

Tasks:

• explain how volcanoes are arranged and what danger they pose;
• tell what an acid-base environment is;
• arouse a child's research interest;
• develop self-study skills;
• tell children about the existence of an acid-base environment.

Materials and tools:

• flask or bottle;
• cardboard for the manufacture of "mountains";
• plasticine to shape the volcano;
• water;
• soda;
• lemon acid;
• orange or red food coloring or gouache;
• dishwashing liquid;
• mixing container and spoon;
• stapler;
• Plastic container;
• small figures (different types of animals, trees, stones).

Experience progress

1. Making a volcano.

First you need to find a suitable container. You can use either a flask or a small juice or yogurt bottle. To make the bottle look like a mountain, we make a blank out of cardboard. Cut out the circle, make one cut along the radius. Fold the circle into a cone and fix it firmly with a stapler. Cut off the top of the cone.

We insert our container inside the figure - we get the frame of the volcano. With the help of plasticine, you need to give the volcano a shape: cover the cardboard with plasticine, make a "crater", masking the neck of the container.

Place the blank of the volcano in plastic container(or in the basin). We create an entourage with different types animals (dinosaurs, animals), trees, stones. We put stones at the foot of the volcano, arrange trees, arrange animals.

2. Prepare 2 lava solutions

The first solution: we collect 2/3 of water in a container, add food coloring (or gouache), a few drops of dishwashing liquid (so that there is a lot of foam) and 5 tablespoons of baking soda.

Second solution: dilute citric acid (the recommended ratio is 5 tablespoons to 1.5 cups of water).

3. We start the "eruption"

Stir the mixture thoroughly in a volcano bowl. Slowly pour the solution into the mouthpiece. citric acid.

Watch the magic happen: the dormant volcano wakes up and turns into a fire-breathing mountain!

Experience result

A fiery red foam erupts from the volcano's mouth.

Scientific explanation

The volcano erupts as a result of the interaction of two substances - soda and citric acid. In chemistry, this process is called a neutralization reaction. Acid and alkali (soda) neutralize each other by releasing carbon dioxide. The CO₂ foams the mixture poured into the vent and causes the mass to overflow over the edges of the crater. The dishwashing detergent makes the lava bubble more. We recommend doing another experiment with a volcano, but with luminous lava.
