A volcanic eruption is a formidable and exciting phenomenon. It captivates the imagination of adults and children. To clearly explain to a child what a volcano is, you can make a volcano yourself at home. And even show the eruption.
Necessary
Paper, scissors, tape or glue, compasses, ruler,
Instructions
Step 1
First you need to draw a large circle on a piece of paper using a compass. Then it needs to be cut and rolled up like a cone, glued or fastened with tape. From another sheet of paper, you need to twist a tube to make the mouth of a volcano. The tube must also be fixed so that it does not unfold. Then we need to put our cone on this vent and fix everything again. Next, we need to cut out a piece from paper that will denote land. Here you can give scope to your imagination and choose any shape. Then, using tape or glue, we should attach our volcano to land, and then wrap it all over with tape, coat it with glue and sprinkle with sand to make it look more natural. You can take colored sand. After that, you can even paint the volcano to make it look like a real one.
Step 2
Now you can start preparing the eruption. Do not be afraid, at home it will not do any harm. What is an eruption? This is the release of gases and ash, as well as hot lava. To simulate the eruption process, you need to take a little bit of ammonium dichromate powder. It is included in the sets of the "Young Chemist" type. Then you need to build a small funnel from foil. plunge it into the mouth and pour powder there. After that, you need to set fire to the powder with a match. Here the eruption will begin. Green flakes of ash will burst out of the vent, they will cover the slope of the volcano.
Step 3
In order to make the spectacle more natural, it is necessary to take care of the lava as well. No self-respecting volcano can do without it. Lava is easy to make. You need to take some baking soda and mix it in a test tube with food coloring or just beet juice. Then the tube should be inserted into the throat. In another test tube, mix water, vinegar and soapy water. When this solution is poured into the mouth of the volcano, where there is already a test tube with soda solution, red lava will flow from the mouth. The delight of those around you is guaranteed.
