Creating a working model of a volcano that will foam (a la smoke) and spit lava is actually not as difficult as it seems.

And such a toy will always come in handy for entertainment, as original decoration table, or even school project that will amaze teachers and classmates.

If you have children, let them help you. Not only because the process is so easy that everyone in the family can do it, but also because you will be able to teach them a lot during the creation.

You will need:

Empty two-liter bottle;
- spray or acrylic paints;
- transparent sealing composition;
- baking soda;
- liquid dish soap;
- white vinegar;
- brushes for paints;
- papier-mâché paste, or salty dough, or putty, hardening like gypsum;
- a piece of strong plywood;
- newspaper;
- red food coloring

1. Place a piece of plywood at least 21 cm long and wider than the approximate diameter of your future volcano on the floor - this will be the base on which you can transfer your creation. It will also prevent lava from getting on other surfaces (the lava is painted!) during the eruption.

2. Use salt dough, hardening plastic, or papier-mâché paste to form a mountain around an empty two-liter bottle placed right in the middle of the plywood. Be sure to remove the cap from the bottle.

3. Form and stick the open top of the volcano on the model so that it fits snugly on the top of the bottle, but hides the bottle itself.

4. Sculpt parts of the ridge and channels, you need them to start at the very top of the volcano and go down in uneven paths - so that lava can flow beautifully along them.

5. Let the volcano dry properly - given the size and amount of plastic/papier-mâché/dough, this can take a long time.

Then color it acrylic paints with brushes or spray paints. Draw a mountain river for a change.

The top of the volcano mountain can be left white or dark for classic version, or immediately paint it red and yellow for a special effect during the eruption. plastic plants, which are usually placed in an aquarium, can be cut and attached to the volcano with glue - you get trees.

6. Spray the volcano and plywood with clear sealer after the paint is completely dry.

7. Mix one tablespoon liquid soap for dishes, 1 tablespoon of baking soda and a few drops of red food coloring in a cup (better use paper cup so as not to wash a regular cup later).

8. Carefully pour the mixture into the bottle in the volcano (use a funnel).

9. Place the completed volcano in an open area where it will not splatter anything, preferably outdoors.

10. Pour ¼ cup of white vinegar into a bottle and step aside to watch your volcano erupt.

Additions and warnings:

Use balls of crumpled newspaper spread around the bottle - under the plastic / dough / papier-mâché paste - to give the volcano the desired shape, but make sure that the surface of the mountain is hard and smooth so that later the volcano can be put into a box and saved for later. use;

If the lava is too thick, add 1 tablespoon of water to the soap and stir;

- If you are going to use the volcano indoors or on a table, reduce the proportions of the mixture in the bottle;

To use the volcano again later, simply wipe it with a damp, clean cloth - from the traces left by the liquid;

Together with the time required to dry the volcano, it will take at least two days to create it;

Do not try to close the bottle after you have added vinegar to the baking soda mixture inside: as a result of internal pressure due to a chemical reaction, the bottle may simply explode.

So, as you can see, it’s easy to create your own little volcano, and then the pleasure will stretch for long years- children are delighted with such a "live" toy! It is no worse than purchased radio-controlled models.

During a volcanic eruption, ash clouds are thrown into the air, and lava flows along the slopes. This is a very exciting sight, it is life-threatening to watch it in close proximity.

But you can make a volcano at home and conduct experiments daily, admiring the eruption without a threat to life and health. By demonstrating active volcano friends, you will surprise them. You can prepare a presentation for a school lesson, and thereby add variety to boring lessons, and teachers in geography and chemistry will surely mark your efforts with good grades.

First make the volcano itself.

How to make a paper volcano

To make a volcano, it is best to use thick paper or cardboard.

Draw a large circle on paper. Cut it out and glue the cone.

From the second sheet of paper, twist the tube and glue it. This will be the mouth of the volcano. Put a cone on it and fasten the structure with glue.

Cut out the ground from the third piece of paper. It can be given any shape, the main thing is that it should be in size more ground volcano. Glue the volcano to the ground, cover it with tape. Apply superglue on top and sprinkle with sawdust, sand. You can use colored sand. Paint the model with gouache or acrylic paints and give the volcano a natural look.

To prevent paint from flowing during or after the eruption, cover the volcano with a protective layer. The composition can be prepared independently: mix 1 part glue and 3 parts water. After thorough drying, the volcano model is ready for use. Lava in a test tube is inserted into the mouth of a volcano.

Volcano how to make from plasticine

Plasticine is divided into 2 parts.

The first part is rolled into a pancake (base or land). From the second part, fashion a hollow cone, with a hole in the middle.

Place a bottle with a cut neck on the base. Put a cone on top, stick around the bottle opening with plasticine. Fasten the base and cone of the volcano together to form an airtight construction.

Color the model and sculpt the slopes. The prepared substance for lava is poured into the bottle through a watering can.

How to make a plasticine volcano model the second way

Instead of plasticine, you can use salt dough, modeling mass, papier-mâché.

Glue the bottle to the base (upside down plastic bowl, thick cardboard, chipboard) with tape so that you get a cone-shaped tent.

Cover with plasticine on top. Form lava flows, mountain range elements, channels. If you used salt dough, dry the volcano.

Now you can paint the model. For a more spectacular eruption, red paint can be applied to the mouth of the volcano. Once the paint is dry, apply a clear sealer.

Attach plastic plants to the base (usually they decorate aquariums) - you get trees and shrubs. Dry the volcano well again before use.

How to make a cold porcelain volcano model

If you wanted to use modeling mass to make a volcano, but did not find it in stores, or the price turned out to be high, you can prepare cold porcelain. This is soft material, homogeneous in structure. It is convenient to sculpt from it small parts, because it is very plastic, and hardens when solidified.

Mix one part starch (corn or potato), soda, water. Add a drop of vegetable oil.

Put the mixture on the fire and cook until it thickens, stirring constantly. Remove the thick mass from the pan and cover with a damp towel. When the mass becomes warm, knead it. It should be soft, and resemble plasticine. The mass can be dyed desired color during cooking. Best for this Oil paint. But keep in mind that then "cold porcelain" will quickly harden. So that the mass does not stick to your hands, grease them with oil or a fat cream. Sculpt the volcano as described above and let it dry. Then paint with acrylic paints.

How to make a soda volcano

The easiest way to make lava is from baking soda and vinegar. The quantity is given for a volcano with a "volume" of 100-150 ml.

1 st. mix a spoonful of soda with 1 teaspoon of dishwashing detergent (preferably red), and red dye (beetroot juice can be used). Stir the mixture well, if the lava is very thick, add water. Pour it into the crater of the volcano.

To start the eruption, you need to add 2.5 tbsp. spoons of vinegar. The vinegar will react with the baking soda and the secretion will begin. carbon dioxide. As a result, a bubbling red foam will form.

How to make a homemade green ash volcano

For this experiment, you will need ammonium dichromate (NH4) 2Cr2O7. It is included in any standard set " Young chemist". The experiment must be carried out on a non-combustible surface.

Pour ammonium dichromate into an unnecessary jar of tin 7 cm high. In the center of the slide, make a recess and put a cotton swab moistened with alcohol.

From brown paper, roll a cone 15 cm high, 20 cm in diameter. Cut off the top of the cone by 5 cm. Cover the reagent jar with the cone. Make sure that the cone is slightly lower than the slide, if necessary, cut the paper further. Set fire to the cotton wool and admire the flying green flakes.

How to make a do-it-yourself volcano that erupts with a sheaf of sparks

The eruption turns out to be spectacular, but it must be carried out, observing the rules for working with combustible substances, and conducting the experiment on the street under the supervision of adults. If careless, you can start a fire or get fourth-degree burns.

Mix 4 parts of potassium nitrate with 2 parts of aluminum (source of sparks) sawdust and 1 part of sulfur. To get enough sawdust, drill a few holes in the metal.

On the bottom of the cardboard sleeve (you can buy it or take it after the used factory pyrotechnics, you can make it yourself) install a clay plug. The wall thickness of the sleeve is 4 mm. Pour and tamp the mixture into a sleeve. Cover with a cardboard circle on top (its diameter is equal to the inner diameter of the sleeve), and then fill it with plaster.

In the middle of the plaster plug, drill a hole for the pyrotechnic mixture and pass the wick. This will be the crater of the volcano, before the eruption, light the fuse and move to a safe distance.

Do-it-yourself paper volcano model polyurethane foam and plasticine: master classes with detailed instructions

Surely, many of you have seen on TV or on videos on the Internet such a bewitching and unusual sight as a volcanic eruption. Of course, to observe this manifestation of the natural elements live is very difficult and even extremely dangerous. However, you can easily make a do-it-yourself volcano model and admire this natural beauty at home. With this model, you can easily demonstrate to your children how volcanoes work. No doubt young explorers will love it.

Before you start working on the layout, it would be best to find out how the volcano actually works. Read thematic literature, watch videos and pictures of the volcano in the section. This will give you a better idea of ​​where to start working on the layout. We only recall that the volcano must consist of magma, craters and lava.

We offer you some unusual and interesting options making a do-it-yourself volcano model.

Model of a volcano from polyurethane foam and polystyrene foam: a detailed description and instructions for implementation

Thanks to this do-it-yourself volcano model, you can clearly demonstrate to children the structure of this natural mystery, show it in section and action.

For work, you will need mounting foam, polystyrene foam, tile adhesive, varnish and paints. As you can see, all necessary material very affordable.

Styrofoam is used here, as well as the basis of the structure, and to form the cone of the volcano: we glue the pieces of foam in layers. From mounting foam we make lava flowing from the mouth of the volcano. We paint the resulting model of the volcano with paints, cover it with a layer of varnish and enjoy the result.

We make a model of a volcano from plasticine with our own hands

In order to make a model of a plasticine volcano, you will need:

• Plasticine
• Large plastic bottle
• Building mix
• Brush and watercolors
• Scissors
• table vinegar

Get to work. Start by cutting off a large plastic bottle. upper part with a neck. You won't need the bottom part, so put it aside. Carefully cut off the neck from the top of the bottle, leave a small gap on it.

Knead the plasticine in your hands until soft and sticky. Paste the cut part of the bottle with plasticine and give the workpiece the necessary shape of a volcano.

AT building mix add water and knead until the consistency of thick sour cream. Next, apply the mass to the base of plasticine.

Insert the cut neck of a plastic bottle into the mouth of the volcano, cap down. Mask all flaws with building mixture.

Leave the resulting structure in a warm and dry place until completely dry.

You can demonstrate the action of a volcano with a mixture of soda and table vinegar. Simply pour two tablespoons of baking soda into your volcano's crater, then pour in the dyed vinegar. Enjoy the eruption of a homemade volcano.

How to make a model of a volcano out of paper: papier-mâché technique

A model of a volcano at home can also be easily made from paper using the papier-mâché technique.

You will need the following materials:

Use heavy cardboard and a plastic bottle to form the base of your volcano model. To do this, glue the bottom of the bottle to the cardboard. Next, starting from the neck of the bottle and ending with its base, stick the strips of adhesive tape so that they form a cone. Glue strips of paper to the resulting cone.

Cook the paste: mix one part flour with two parts water. Saturate pieces of paper with this composition and glue the entire base of your structure, giving it the shape of a volcano. Leave the layout to dry completely in a warm and dry place.

Then, start painting the structure. At this stage, you may well entrust the work even to your children. Again, leave the layout to dry completely.

Now you can start demonstrating the eruption of a makeshift volcano. Pour warm water with liquid soap in a bottle and add table vinegar there. Get ready for an exciting spectacle!

A self-made model of a volcano will come in handy if you want to take part in an exhibition of themed crafts, or just have fun and unusual time with children, watch an exciting experiment. And if you have any difficulties when creating a model of a volcano or when conducting an experiment, pay attention to the attached videos.

Layout model Papier-mache Layout volcano Paper Glue

Greetings to all, dear and beloved neighbors!)) I decided to show you my latest work. The child was asked to make a model of a volcano to school (carry it tomorrow. How to drag it?! I have absolutely no idea yet))). And the abnormal mother, instead of letting the child do something simple and easy, took up the work herself ((But he inspired me and helped me in any way he could. He asked me to add some details, for example, trees on fire and always flowing lava. He composed a whole story about the eruption.

to be honest, I don’t like how lava looks, if you have any recommendations or advice, dear craftswomen, I would be grateful! I have to make 1 more layout in a year or two for the younger one (I hope we will still be at this school))) And this is how the structure of the volcano itself looks like - well, it just exceeded all my expectations! I'm so glad it worked out. I have never worked with papier-mâché. This is the first time!

closer view. I love the result so much! uuuuuuuuuu

trees made of felt on wire trunks, inside there is a little filler for volume. Glued with hot glue

trees on fire - printout on photo paper (glued 2 sides together, wire trunk in the center) glued a tree on hot glue

top view (even before the varnish. And the acrylic spray varnish. After applying it, the colors became brighter, especially near the lava)

now a few pictures of the work in progress for those who are interested. It's almost finished here.

here is the stage of painting

dried papier-mâché, layout ready for painting

in the process of gluing

I learned how to make papier-mâché using MK Swetlana Romanteeva http://stranamasterov.ru/node/740837?c=favorite Thank you very much, Svetlana!

and this is the beginning))))) when I was looking for MK how to make a layout, I found only general description with pictures of the finished product. So, I did everything according to my own feelings. I hope my detailed pictures will help maybe someone in the future. Fascinating activity, I'll tell you!)) It remains only to master how and from what the "lava" will bulge out. In the very center plastic bottle, glued firmly firmly (I cut off the neck).

Thank you all for your attention! I hope I didn't bore you with the number of photos))

Great job! Bravo!

Thanks a lot for the kind words, Julia!))) namesake))

Well done. A wonderful spectacular craft - SHINE. And I am the same abnormal mother, I try to embody all the fantasies of children and help in all crafts. By the way, you can demonstrate lava like this: take any detergent for dishes (we took Fairy) + potassium permanganate (more), add hydrogen peroxide (it is advisable to take a larger percentage, we took an oxidizing agent from hair dye 6-9%) - amazing lava turned out, but the reaction will take so long if sometimes you stir with a stick , crawling and crawling. Maybe add some dye. We saw this method in some educational program. They also make lava with soda http://stranamasterov.ru/node/349573.

Thanks a lot for your kind words and your attention, Irina! I shake hands with my colleague mom!))))))) Thank you for the lava recipe. Now I'll look for the ingredients and test. Something is a pity for the craft if the peroxide flows over it. first I'll try it in a basin, I'll show it to my children. And at school I’ll offer it, if they agree, then we’ll test our volcano for strength!)) I didn’t get any reaction with soda, but at first there were plans for it

Sorry, I thought about that too. Just try it carefully, I don’t remember the proportions, the higher the percentage of peroxide and the more potassium permanganate, the higher the fountain, it’s checked. I’ll also add: something terrible turns out with dry peroxide, you need to drape faster and further away (I saw it in the program, the lava ran like a fountain).

Thank you very much for the clarifications!)))) chemists-technologists))))))) I definitely don’t have dry peroxide)))

Nice fake!! And the lava is like real, I liked it!

Thank you very much Victory for your kind words!

but yours is cool!)) we made lava with soda, vinegar, dye and fairies - I gave everything to my son in jars-boxes with me, we had a “test drive” at home before that)) just give him the packages to demonstrate on them - if everything leaks too much, it was easier to clean)))

Thank you very much for your feedback, Tatiana! Something I don’t have any reaction with soda with vinegar is violent, no matter how much I take. Well, okay. I'm afraid at school they won't mix-fire the eruption. All the guys must bring their volcanoes on assignment. If someone else decides to mix the hellish mixture - then I'm scared for the teacher!))) And the kids are still too small in age for an independent experiment.

we seem to be foaming and climbing. although the height of the volcano may still play a role. ours, according to the sensations, will be lower))) but it was at the beginning of the 2nd grade, in September. Small successfully coped, it seems,))) I will try to find the instructions in the internet, I confess, I did not save it.

Perhaps our bite is weak. Well, okay! We will experiment at home with the children, and take the model to school.

ordinary vinegar, table, 9% it seems. baking soda. water was not added, although some versions do with water. foaming. well, how much foam)))))) I’ll be glad if it helped - suddenly you decide to have fun with your sons in the summer and study tectonic processes, mine periodically encourages me to do this)))))

and the volcano was not damaged after and was even washed))))

Thank you Tatiana!))

it's just OUT. Well, your imagination can only be envied.

Hi Anut! Thank you for supporting my experiments!)) And guess what? Now I'm learning how crafters make papier-mâché crafts more thoughtfully and I want to make a couple to start with. I'm a little fed up with bottles (except for the marine series) for today!))) I'm delighted with papier-mâché! So many perspectives! Wooooooooooo! but I don’t need to envy, you have your own imagination and inspiration over the edge))

You also sculpt volcanoes, beautifully and monumentally

How the forces of evil triumphed

That the crater sighed sadly,

And the stones flew from the vent,

And black ashes fell down.

Cracked slopes,

Magma poured out of them,

Lying, mountains and rocks, buoys,

The picture of disasters was a success.

Although he did a lot of trouble,

But still the sun shines,

And there is no more worry

Yet he fell asleep for hundreds of years.

Thank you, Nikolai!))) Well. on my account so far 1 pyramid and 1 volcano (everything for the school)))) And really, let them (volcanoes) sleep and rest forever!

We did a lava eruption! I ended up using Irochka-Manyuni's recipe)) Thank you very much for the tip, Ir.

WAAA. with potassium permanganate it turned out stunning.)))) perhaps I won’t show this to the child, otherwise he will drive him to the pharmacy.

Tatyana, mine just tortured me, “what?! So when? and now he will do the experiment? ”While I was looking for ingredients in our pharmacies and in the home supplies of the first-aid kit)) in our lava there is still a little red food coloring (it is liquid)

Tell me, please, how did you make lava so cool, also from papier-mâché?

I'm talking about convex streams, I don't know how to explain, I hope you understand what I mean)))

OBJECTIVE OF THE PROJECT:

Learn how to make an erupting volcano at home, from improvised means

Find out what happens when you mix baking soda and vinegar

HYPOTHESIS:

is it possible at home

conditions through

improvised means

make a volcano.

1. What are volcanoes?

2. The structure of the volcano - a crater, vent, magma, lava.

3. What is vinegar?

4.What is baking soda?

5. Conclusion.

What are volcanoes?

• Volcanoes - geological formations on the surface bark The land where magma comes to the surface, forming lava , volcanic gases, stones. A typical feature of volcanoes, by which they are easily recognizable, is their conical shape.
• The science that studies volcanoes is called volcanology , geomorphology .

And people who study volcanoes are called volcanologists .

Volcanoes are divided depending on the degree of volcanic activity: into active, dormant and extinct.

The eruption process can last from several hours to many years.

Among the various classifications, general types of eruptions stand out: location - terrestrial, underwater, subglacial.

A volcanic eruption is a grandiose and impressive natural phenomenon. With ancient times it evoked superstitious horror in people, as if demonstrating their defenselessness before the formidable elements. The word "volcano" itself comes from the name of the ancient Roman god fire Volcano

The structure of the volcano

Crater - bowl-shaped or funnel-shaped depression on a peak or slope volcanic cones

vent- a vertical or almost vertical channel connecting the volcanic focus with the earth's surface, where the vent ends with a crater.

Lava – the word comes from Latin word labels - collapse, fall. Lava is formed during a volcanic eruption magma to the surface Earth . Lava is hot liquid or very viscous melt rocks erupting on the Earth's surface during eruptions volcanoes . When lava solidifies, it forms rocks , may form lava plateau . Temperature lava ranges from 500 up to 1200 °C

Magma - is a natural, red-hot, liquid melt that occurs in earth's crust at great depths, and when cooling, forming igneous rocks . erupted magma - This lava .

Now you need to pour red gouache into the "crater of the volcano" and mix everything.

Then add vinegar to the glass QUARTER GLASS )

Baking soda - sodium bicarbonate (other names: baking soda, sodium bicarbonate, sodium bicarbonate). It is usually a white crystalline powder. Used in chemical

food, light, medical, pharmaceutical

industry, color

metallurgy, supplied in

retail

Vinegar - a product with a significant content acetic acid resulting from microbiological synthesis via acetic acid bacteria from food alcohol. Substance,

known from ancient times. Colorless or

lightly colored transparent

liquid with a sharp-sour taste and a specific aroma.

Conclusion:

At home, perhaps arrange a volcanic eruption what happens when you combine vinegar and baking soda chemical reaction with the release of carbon dioxide

gas (multiple

bubbles ).

the end

Not everyone has the opportunity to show a child a real volcano - they are far away, and walking on them is dangerous. But in order to get acquainted with the principle of the action of volcanoes, to study the processes that take place inside, a small volcano, made as simple as possible with your own hands and launched, is quite suitable. Showing a miracle to a child is very easy, and this craft can also be used at school for projects.

Learning to make a big do-it-yourself volcano from salt dough

There are many ways to make a volcano. In one option, you will need salt dough. Also needed for work: flour (about 400 gr.), Salt (200 gr.), Water (150 ml), paints (watercolor, gouache, acrylic or food coloring, glass cup or plastic bottle, vinegar, baking soda, plywood or a piece of very thick cardboard.

First, the dough is kneaded. It should be steep, very salty, thick, but plastic. Ideally, it should not stick to your hands, but it is easy to acquire the necessary shape and be pliable. The base of the volcano is formed from salt dough.

A glass or a bottle is placed in the center, the mass is distributed around and a mold of the mountain is formed. For greater similarity with the real one, strands of mountain ranges are molded in the layout, holes are made for lakes or furrows for rivers. You can make several holes in the dough with a toothpick. After the workpiece has solidified, branches are inserted into them or ornamental plants from the aquarium.

In the air, the finished cast completely hardens within a few days. You can speed up the process in the oven; at a low temperature, the workpiece is baked for about 20 minutes.

The next step is coloring. Paints draw greenery at the foot of the mountain, gold deposits, blue rivers. The top of the mountain is painted in red and white - the color of snow or lava.

In order for the volcano to begin to “breathe with lava”, water with detergent is poured into a glass or bottle that stands in the center. Pour a couple of tablespoons of vinegar inside. Just before the performance, vinegar is poured into the glass. A mixture of baking soda and vinegar reacts and after a few seconds the lava will rise and begin to run down the slopes of the volcano. If you add food coloring to the detergent, then the lava will be like a real one - red.

Such a volcano is easy to make from plasticine. The skeleton of the mountain is made of plywood or cardboard cone. The dimensions of the cone are chosen based on the size of the volcano.

The cone is plastered with plasticine - brown and black in the color of the earth, white and red - the top is covered in snow with lava, the foot is green and blue. You can also make several three-dimensional figurines of trees or animals and place them on the slopes of the mountain.

A glass or bottle is placed inside the cone, a mixture of detergent, vinegar and soda is poured into the middle.

It is important to remember that such a filler foams very strongly, so it is imperative to lay something under the base. A tray with low sides, which is decorated to match the volcano, is well suited.
Papier mache volcano.

You can make a volcano out of papier mache. Required to work a large number of newspapers and papers.

A cone is formed from whole newspapers. Newspapers are crumpled and taped to each other.
Then pieces of paper are glued on top of the crumpled newspapers with glue. There must be 5 - 7 layers for the volcano to be strong. Inside, as in other options, a container is placed, which will be filled with lava. You can cut out animals, plants, birds from paper and place them on the slopes of the future volcano. It is necessary to paint a papier-mâché volcano with paints, acrylic and gouache are well suited - they sigh for a long time, but are durable and will not flow during an eruption.

If you ask your dad for help, you can get a great foam volcano. Foam is good because with a gun you can create various forms, which will be very similar to a real mountain. The foam dries for a couple of days and only in natural conditions, it is not worth speeding up the process - the volcano can lose its shape.

A lava container is placed in the middle of the volcano. It can be a jar, a bottle or a glass. If the workpiece is immediately filled with foam, along with the container, then it will be impossible to pull it out later. If you first make a model of the volcano, and then make a hole with a clerical knife, then the container can be removed. The foam is easy to cut, it is convenient to use a clerical knife for work - they can cut small holes and neat edges.

Paint comfortably with a wide brush. You need to paint over well so that the pores of the foam are not visible under the paint. Such a volcano will be light and beautiful. The slopes of the mountain are easy to decorate with plants. Figurines of animals and birds.

More ideas on how to make volcanoes can be seen in a selection of videos.
