Tropical summer landscape Draws a cold on the window Why does it need roses? Apparently this is Winter yearning for spring. (D. Kedrin)
Project topic: “Why do frosty patterns appear on windows in winter?”
Purpose of the study: to find out why bizarre frosty patterns often appear on windows in winter.
Objectives: study the literature and select interesting information about how frosty patterns appear on windows; find out why frost patterns come in different shapes; observe the appearance and disappearance of frosty patterns on the windows; draw conclusions and summarize the results of observations.
Hypothesis: Suppose that the shape of snow patterns can predict the weather.
How do snow patterns appear on windows?
In winter, the air near the window glass cools down greatly and some of the water vapor from it settles on the cold glass in the form of ice crystals. Then these crystals begin to branch and grow, “drawing” snow (frost) patterns on the glass.
In order for crystallization to begin, the first ice crystals need to settle on something. Let it be a speck of dust. Or a trace from a rag used to wipe the windows.

Do frosty patterns appear on all windows?
Patterns do not appear on the window if the window is open. Frost patterns cannot appear on a double-glazed window Previously, when they stopped heating the stove in the evening, the glass temperature dropped below 2 degrees. Droplets of water froze on it.
What types of frosty patterns are there?
Dendrites (tree-like formations). Dendrides are formed if the air humidity is increased, and the cooling of the glass began at a positive temperature and continued with a further decrease in temperature.
Dendrites on the mirror of our car
Trichites (fibrous forms). Trichitis occurs on glass precisely when there are a lot of scratches, nicks and dust particles.

When do marvelous pictures of ice crystals form?
When there is a sudden cold snap, the temperature of the windows becomes lower than the air temperature in the room. Warm water vapor in the humid air in the room settles on them. A thin, almost invisible layer of water appears on the glass.
Folk signs: if the branches of the patterns were directed downward, the weather will be snowy and cloudy; if up - clear and sunny. straight patterns foreshadow even greater cold, oblique ones - thaws, and more intricate patterns - snowfall.
Analysis of observations and conclusions The goal that I set for myself has been achieved. I found out why bizarre ice patterns often appear on windows in winter. I made the following conclusions: Frosty patterns on glass are large ice crystals growing from water vapor at the border of heat and cold; The type of pattern on the surface of the glass depends on the temperature inside and outside the room, the humidity in the room, the thickness of the glass and how dirty its surface is.
Analysis of observations and conclusions With high-quality glass sealing, patterns do not appear on the glass, because no temperature difference. Frosty patterns do not form on modern windows (double glazed windows). My observations support the hypothesis that the shape of snow patterns can predict the weather.

Thank you for your attention!
People of the older generation remember very well what magnificent patterns formed on the windows during severe frosts. And this beauty appeared in winter, in almost every home. This phenomenon has always amazed us, and at the same time raised the question - who creates such beauty?
No matter how beautiful these window patterns were, in most cases they have disappeared from our reality. And the point is not even that most of us have plastic windows on which frost does not freeze. Even on classic wooden windows, now more often just a flat white field is formed, with some touches. And only in very few places can you still see these fantastic pictures in winter.
In fact: why did the frosty patterns on the windows practically disappear? In order to answer this question, it is necessary to know the properties of human nature. It turns out that human energy is formed by the soul. And as it has now become known, this energy is capable of going beyond the body and influencing external substances and objects. Human thought can have a particularly strong impact on water.
One Japanese researcher carried out experiments confirming this position. As a result of his research, he found out in particular that depending on the quality of thought, crystals of the appropriate quality are formed. That is: positive thoughts form beautiful crystals - and negative thoughts form ugly crystals. To do this, it is enough for a person to generate negative energy.
How can this information be connected with the phenomenon that we are talking about here? And for this we must again turn to human nature. We have found out that the human body works from the energy of the soul. And, of course, the main potential of this energy is activated during the day. Most of this potential goes not only to the work of the body’s muscles and accelerated biological processes, but also to thoughts. At night, much less soul energy is spent on these processes. This means that some energy potential remains unused. And since the human soul is designed for constant dynamics without rest, its potential, freed from bodily needs, tries to manipulate external elements. And water molecules that condense and freeze on window glass are quite suitable material for such manipulations. And the souls of people expressed their beauty on the glass windows.
It was like that before. Nowadays, souls rarely allow themselves to engage in “window creativity.” Will a person paint if he has more pressing matters to attend to? Obviously not. What kind of affairs have appeared in human souls?
As you know, the soul, being in the body, is obliged to take care of its biology. One of the most necessary tasks for it is to ensure the energetic purity of the body. However, rarely do any modern people maintain such purity inside.
Any negative human reaction - be it envy, anger, or immoderation in one's desires - all this literally poisons our bodies. The research conducted by the Japanese scientist fully proves this position. By the way: in an experiment on the influence of thought energy on rice and water, it was found that the positive energy of thought turns this mass into kvass. From the perspective of human perception, kvass is a useful education. But the negative energy of thought caused the rice to become moldy. From a human perspective, this is already “poison”.
It's no secret that the modern world stimulates our negative reactions. All this poisons our biology. “The Creator's Mosaic” describes a technology that allows one to cleanse the body of the “dirt” that a person has accumulated during the day. And since few people know about this technology, we do not try to cleanse ourselves, and with such “poisoning” we calmly go to bed. As we have already said: a person who likes to draw will not sit down for this activity if the house is dirty.
Remember how a negative thought poisoned the water with rice, causing this mass to become moldy. The same thing happens with the biology of the body; if a person produces many negative reactions during the day, the body will be poisoned. Accordingly: the liberated potential of the soul will not even try to draw window patterns - it will strive to get rid of the “dirt” that a person formed during the day.
Now we know why the frosty patterns on the windows disappeared in most families. It's all about creating more negative reactions in people. And we are stimulated to this not only by society, but also by watching films and programs that carry negativity.
In order to not clog your body, you need to not only learn to filter screen dirt, but also learn how to properly respond to external negativity. The instructions for life set out in the texts of “The Creator's Mosaic” are ideal for such lessons. Bring joy to your soul - study these materials thoroughly! And besides, this will bring great joy to your body - you will no longer get sick. Probably after this your soul will be able to draw beautiful pictures on the windows at night. Good luck!

Progress of the lesson
Guys, today I will tell you a fairy tale about Winter, but not a simple one, but a magical one. She loves to do miracles. There lived a little Droplet on a big white cloud. She lived alone and was bored. Droplet wanted to see what was there behind the cloud. She decided to jump from the cloud. As soon as she flew down, she suddenly turned into a beautiful Snowflake.
Guys, tell me why the Droplet turned into a Snowflake? (children's answers). Let's remember what happens to water in winter? (children's answers).
Now listen to the poem and tell me what I will tell you about today.
This morning I couldn’t take my eyes off the glass.
Here again he gave me his surprise
This fabulous artist Freezing. A miracle appeared before me -
Artist frosty fruit of creation
He's not just painting something there,
And he draws a fairy tale on the window.
What will I tell you about today? (children's answers). Guys, I suggest you see what there are patterns(view presentation « Frosty patterns on the window» ).
Every winter we have miracles happen in windows, appear of incredible beauty patterns! It was always interesting where do they come from, and who draws them?
The wonderful pictures that appear may resemble palm forests, garlands of flowers, or branches of fir trees. How do these bizarre frosty patterns on the windows?
Guys, what do you think? Frost draws these patterns?
(Children's opinions: Blows cold on the glass, like magic, throws on snowflake windows, and they stick to the window.)
Actually from the cold, frosty air, water droplets that are present in the air settle on the cold glass, freeze and turn into pieces of ice, similar to the thinnest needles, which spread in different directions along the glass. During a cold night, many, many of them are formed, they seem to grow on each other.
friend. And in the end they turn out different patterns and drawings, in which you can even see the outlines of familiar objects. This is how they are formed frosty patterns, and the artist here, without a doubt, is Freezing. The result is such beauty that you can’t tell it in a fairy tale or describe it with a pen. By the way, in Germany frosty patterns on glass that’s what they call it – "ice flowers".
The patterns are different: some are formed at the bottom windows, others - in the form of narrow strips of frost, which will be the stem of the plant.
One girl decided to watch how frosty patterns. "It's time frosty morning. When I woke up, I looked out the window. The icy ice on the glass sparkled whimsically in the sun. patterns that I drew on the window freezing. It's hard to believe that all this was drawn without the help of human hands. It is especially beautiful when a ray of sunlight falls on the window, then the whole picture sparkles. Watching the snowy patterns, I noticed that they colored: sometimes blue in cloudy weather, sometimes yellow in the sun, sometimes pink and purple at sunset. In the evening, when it becomes completely dark outside the window and the glass looks black, frosty patterns sparkle like stars.
Interesting I also saw patterns on the windows of my dad’s car.. The glass seems to be covered with a coat of ice needles. Let's go, glass frozen, dad doesn’t like it, but for me the most beautiful picture is drawn on the glass.”
Is it for everyone? Frosty patterns appear on the windows? It turns out not. Patterns do not appear on the window if the window is open. With high-quality glass sealing, patterns do not appear on the glass, because there is no temperature difference. Patterns on glass are short-lived - the sun begins to warm up, and frosty patterns become less clear, blur and flow down the glass in streams of water. They disappear forever.
About frosty patterns are signs, riddles and poems. Once upon a time
frosty patterns people defined weather:
If the twigs patterns directed downwards the weather will be snowy and cloudy;
If up – clear and sunny (showing illustrations frosty patterns) .
Guess the riddles:
Everything turned white during the night, the wind blew, and freezing
And there is a miracle in our apartment! Brought snow to us from the north.
Outside the window the yard disappeared. Only since then
A magical forest has grown there! On my glass.
Poem:
Without waiting for the warmth,
In the middle of a winter day,
The flowers have bloomed
On my window.
I approached the flowers
My cheek became wet
Because windows
I touched lightly.
I approached the flowers
But they didn't smell.
Why did they grow up?
On winter days?
But frosty patterns you can draw it yourself; special paints are even sold for this and other options for painting glass are offered (toothpaste, white gouache or artificial snow). But none of the people can do it as intricately, as magically as nature can do it (or Grandfather Freezing) .
Guys, what interesting things did you learn today? What did you like most? What signs do you remember? Tell your parents about them.
On frosty days, stunning ice patterns appear on the windows in the form of extraordinary stars, fancy curls, fabulous trees and flowers. In order for ice gardens to bloom on the windows, it is necessary that the air in the room be humid and the temperature outside the window be below zero.
Why do frosty patterns appear on the window?
Everyone remembers the parable that Santa Claus draws frosty patterns on the window. He quietly creeps up to the window at night and paints unique frosty pictures on it with a thin icy brush. In fact, everything is much more prosaic. If the air in the room is humid, and the temperature outside is zero degrees Celsius or lower, then excess moisture condenses on the cold surface of the glass. Here the water vapor cools and changes from a vapor to a solid state, forming thin crystals.How ice crystals form
Any glass that looks perfect has microscopic nicks and scratches. The moisture that settles on the surface of the glass crystallizes first of all on these tiny defects, and only then more and more cling to the first crystals, forming patterns. Sometimes, for the appearance of icy patterns, all it takes is dust particles that litter the surface of the glass, or stains that remain after washing the windows. Drafts and air currents also contribute to the appearance of patterns. According to the method of formation, frost patterns are divided into two types: dendrites - branchy patterns that resemble trees, and trichites, which are more like stars.Tree-like dendrites
Dendrites form at the bottom of the glass, where the water layer is thicker. Here wide trunks of frosty patterns appear, on which thinner branches gradually grow. The dendrites in the lower part of the glass are wide and thick, and in the upper part they are narrower and thinner. This frosty pattern resembles the thicket of an impenetrable fairytale forest.Trichite star patterns
If there are a lot of nicks, dust particles and scratches on the glass, then trichites appear on it - frosty patterns that look like stars. First, the epicenter of the pattern - a speck of dust or a jagged - freezes, and then other crystals join it, like rays. As a result, frosty patterns look like a cluster of snowflakes or. When the temperature outside the window drops, trichites form dense ice fibers.When patterns don't appear on windows
If the air humidity in the room is low and the window has good thermal insulation, then condensation does not form on the glass and frosty patterns do not appear. That is why ice paintings, so familiar to residents of houses with old wooden windows, do not spoil residents of apartments with high-quality plastic windows.Frosty patterns on window glass are essentially the same thing as frost that forms on the ground and on tree branches. The mechanism for the formation of frost and these patterns is the same.
If the air cools, its moisture content decreases. Frosty patterns on glass and needles of frost are formed when moist air is cooled to the freezing point of water, that is, to 0°C. At this temperature, excess moisture contained in humid air condenses on cold surfaces. In this case, the water crystallizes, that is, turns into tiny ice crystals. Thus, water contained in humid air at 0°C passes from a gaseous state to a solid (crystalline) state, bypassing the liquid phase.
Why do ice crystals form such bizarre shapes? This is due to unevenness and scratches on the surface of the glass. Ice crystals form on them first. The crystals are deposited one after another, on top of each other - and amazing, unique patterns are obtained. In addition to glass unevenness, dust particles on the glass surface and air currents also participate in the “drawing” of patterns.
Among the variety of frosty patterns, the most common are tree-like structures - they are called dendrites and fibrous forms - trichites.
Dendrites are formed if the air humidity is increased, and the cooling of the glass began at a positive temperature and continued with a further decrease in temperature. In this case, a water film first forms on the glass, which, when frozen, crystallizes in the form of dendrites. Most often, this process begins at the bottom of the glass because more water accumulates there under the influence of gravity. That is why in the lower part of window glass the dendrites are usually larger, and the higher they are, the thinner and smaller the ice “branches” are. If the glass is moistened evenly during cooling, that is, covered with a more or less even film of water, then the “branches” of dendrites are approximately equal in size over the entire surface of the glass.
If there are scratches on the glass, then a second type of pattern is formed on their sharp edges - trichites. First, narrow parallel crystalline stripes are formed. With further cooling, fibers appear, extending from the main “stem”. Most often, both the “stem” and the “fibers” extending from it are not straight, but slightly curved.
Is it possible to prevent frosty patterns from appearing on window glass in winter? Can!
We have already said that an indispensable condition for the formation of frosty patterns is an increased moisture content in the air and cold glass. If any of these factors are excluded, Santa Claus will not be able to decorate window glass with his paintings.
For example, you can reduce the air humidity near the surface of the glass, then water condensation will not occur on it. To do this, you can place a glass of concentrated sulfuric acid between the window panes - it is known that it absorbs moisture from the air well.
The second way is to prevent the glass from getting too cold. This is done by carefully insulating the outer window glass where it comes into contact with the frame.
