Introduction

I love summer very much, I like to play outside with my friends. But sometimes it rains outside and you have to stay at home. One day mit did not become interesting to find out in more detail - what is rain and where does it come from? And I decided to look for answers to these questions on my own.

Object of study: rain

Subject of study: rain formation process

Purpose of the study: find out how rain is formed

Research objectives:
- find stories about rain, about natural phenomena;

- read, study, note interesting information;
- observe the formation of rain;

Conduct an experiment that will show how raindrops are formed;

Draw conclusions;

Write down interesting facts about rain.

To solve my problems, I used the following methods:

The study of educational literature on the chosen topic.

observation.

Conducting a research experiment.

Selection of photographs, materials on the topic.

Generalization of results and conclusions.

Based on my observations, I put forward hypothesis :rain is drops of water falling to the ground from clouds.

1. What did our ancestors think about rain?

Rain water benefits agriculture and promotes the growth of herbs, fruits, therefore, the well-being of peoples depends on it.

People have long composed legends about rain, called it the tears of the sky, the life-giving force that gives life. At the same time, rain could become a punishment from heaven, leading to a worldwide flood.

There were gods and spirits that controlled the rain, spells to call or stop the rain. In many cultures, a special is performed during a drought. In dry areas, such as Africa, rain is considered a blessing.

2. What is rain.

Rain is drops of water falling to the ground in large quantities from clouds and clouds.

3. How rain is formed.

From solar heat water from the surface of puddles, streams, lakes, rivers, seas and oceans and streams evaporates and turns into steam. Steam is very, very small droplets of water, so small that you can't see them with your eyes.

The vapor is very light, it rises up into the air, very high. There, where always, even on the hottest summer day, it is very cold, like in winter.

The droplets are light, like fluff, they are perfectly kept in the air. Together, these droplets form clouds. Clouds float in the sky and move all the time, because they are pushed by more and more currents of warm air rising from the earth.

4. Why is it raining.

If it gets warmer, the cloud can completely disappear, dissolve - the droplets evaporate and become invisible. If it gets colder, the droplets merge into larger ones - clouds form. In the clouds, the drops become too heavy to continue their soaring in the sky, they fall to the ground - it's raining.

5. More about rain

Raindrops are “balls” ranging in size from a small grain of sand to a medium-sized pea (from 0.5 to 7 mm). If the drops are smaller, such a rain is called. Droplets larger than 7mm in diameter break up into smaller droplets as they fly out of the clouds, so even with a heavy downpour, the droplets will not be larger.

Rains are different, during a heavy downpour, up to 10 cm of water can pour in one hour, that is, approximately “ankle-deep”.

6. What are the rains

Mushroom rain - shallow, drizzling, going into the mushroom season in the light of the sun

Blind rain - rain falling in the light of the sun;

Thunderstorm (rain with a thunderstorm);

Rain with hail;

Snow shower (rain with snow);

Bathing (rolling) rain

Downpour (torrential rain)

Drizzling rain (drizzle)

Striped rain (falling in stripes)

Oblique rain, slanting;

Sitny rain - fine rain, as if "sifted through";

Lingering (overhead) rain;

Rough rain.

7. Signs of rain

8. Interesting facts about rain

1. Tropical rains do not drizzle like those to which we are all accustomed, but fall, just like from a tub.

2. Thursdays in Londonit rains a lot more than on other days. Surprising but true.

3. In Portugal, if the street goes heavy rain you can't go to work.

4. The old Russian meaning of the word rain is “give”, in translation it means “giving life and hope”.

5. The rainiest places on earth are India, China, Japan, Brazil, countries Central America. The most arid are deserts, as well as large areas, western territories and America.

6. In Russia, the largest annual precipitation is on the eastern coast and on (more than 2 m per year). The smallest amount of precipitation is on the northern coast (less than 20 cm per year), and the islands

9. Rain Riddles

Without a path and without a road

Walks the longest.

Hiding in the clouds, in the mist,

Only feet on the ground. ( rain)

He makes noise in the field and in the garden,

But it won't get into the house.

And I'm not going anywhere

As long as he goes. ( rain)

10. My experiences

Experience 1.

Imagine that the water in the kettle is a lake. Electricity will help us heat water instead of the sun.

When the kettle boils, the water turns into steam (Fig. 4).

If steam hits a cold surface, it will turn into water. This phenomenon is called condensation.

We cool the steam with a glass of cold water and ice (Fig. 5).

The steam turns into water droplets that flow down (Fig. 6), just like rain comes from a cloud.

IN
conclusion: When boiling water turns into steam, when cooled, the steam turns into water

Experience 2.

Squeeze a dry ball of cotton tightly. Then they lowered it into a saucer with water (Fig. 7). The cotton ball will unfold and swell with water. Carefully lifted the cotton wool (with tweezers) behind upper part over the saucer. If there is enough water, then drops will begin to fall in the saucer (Fig. 8).

Imagine that we have a small cloud in our hands, it is saturated with water. There was a lot of water. Our cloud has turned into a cloud, the droplets cannot stay in it and begin to fall (Fig. 9). It's raining.

IN

conclusion: the cloud, filling with water, turns into a cloud, the droplets cannot stay in the cloud and begin to fall to the ground in the form of rain.

Conclusion

In the course of this work, I learned that rain is ordinary water that falls from the sky, from the clouds.

Together with my parents, I conducted experiments that helped to see how the formation of raindrops occurs, and why drops start to drip from the clouds.

I realized that rain is one of the links in the chain called "the water cycle in nature." Rain is formed when warm vapor from the ground cools in the air and turns into water droplets.

Thus, my hypothesis is that rain - these are drops of water, in large quantities falling to the ground from the clouds, was confirmed.

Description of the slide:

Subject: Why is it raining? Problem: You may have noticed that when the sky turns gray and the white clouds turn into heavy clouds, after a while it starts to rain. But where does this rain come from? Research hypothesis: it is possible that when it rains, puddles are formed that soak into the ground, and drops from the ground fly into the sky. And when the clouds move together, the drops have nowhere to go and they begin to fall to the ground.

Description of the slide:

About water from the history of the Earth In the history of our planet, water is very important. She plays important role in the life of the plant and animal world of the Earth. Life is impossible without water, but water can exist without life. Therefore, our ancestors believed that water appeared on Earth before life arose. Rain is precipitation that falls from clouds in the form of water droplets. Watching it rain primitive believed that all the water is in the sky. According to other observations, water appeared from under the Earth, where, according to legends, the dwellings of spirits and gods were located. Hence the veneration of springs, seas, lakes and other bodies of water.

Description of the slide:

The science of "hydrology" and the concept of "water cycle in nature". The science of hydrology is engaged in the study of the water cycle in nature, the influence of human activity on it. More than half of the surface of our planet is covered with water. The watery shell of the earth is called the hydrosphere. It is divided into the following parts: 1. waters of the oceans; 2. land waters; 3. The groundwater. Water moves and combines with the help of the global water cycle. The global cycle is the movement of water from ocean to land and from land to ocean through the atmosphere.

8 slide

Description of the slide:

Sun rays warm the earth and water bodies. As a result, the water begins to evaporate and rise high up in the form of steam. It's cold upstairs, so the steam starts to cool down and turn back into tiny, tiny droplets of water or sharp ice crystals. When there are a lot of such droplets, a cloud appears, which we see in the sky. clouds happen different shapes and colors. The wind carries them. When small water droplets have merged into large raindrops that can no longer stay in the air, they begin to fall down in the form of rain.

9 slide

Description of the slide:

The water from the reservoir traveled high in the sky in the form of steam and returned as rain to the earth. This is the water cycle in nature. If it is very cold at the top, then water droplets can freeze and turn into ice balls that will fall to the ground in the form of hail. Snow forms high in the clouds. Snowflakes are made when several ice crystals are joined together or attached to a frozen drop of water. If the snowflakes falling down do not melt, then on the ground will fall snow.

10 slide

Description of the slide:

Properties of water From the school course we are familiar with the properties of water: Water is transparent; The water is colorless; Water is the solvent; The water is odorless; Water flows (property - fluidity); Water expands when heated; Water contracts as it cools.

11 slide

Description of the slide:

Experience. How does the water cycle occur in nature. To do this, we poured water into the pan, covered it with a lid and put it on the included stove. When the water boiled, some of it evaporated and settled on the lid. We shook the lid and the drops fell back into the pot.

observation. Using a microscope, we looked at rainwater, puddle water, and melted snow.

13 slide

Description of the slide:

Observation 1. In October 2013, we collected raindrops in a saucer. We held the saucer overhead, sticking out our hand from the balcony of the second floor, so that foreign objects could not get into the container. In the microscope, we saw a clean drop of rainwater.

14 slide

Description of the slide:

Observation 2. We wondered what rainwater looks like close to the ground. In order to test this, in November 2013 we placed an empty jar on the ground in the yard. When rain water got into it, we carefully examined it. She appeared to be practically clean. Only a small blade of grass fell into the jar. When we looked at a seemingly clean raindrop through a microscope, we saw that there were foreign particles in it. They were some kind of "rags" that looked like slime. We also saw a few sticks.

15 slide

Description of the slide: Description of the slide:

Observation 5. In a jar where it melted dirty snow we saw dirty muddy water. Sand settled at the bottom. The melted snow from this jar had an unpleasant smell. When we looked at a drop from this jar under a microscope, we saw a large number of mucus, small pebbles, as well as many small round-shaped microorganisms moving in different directions.

18 slide

Description of the slide:

Conclusion. Thus, we got acquainted with the ideas of ancient people about water and saw how they understood the mechanism of the water cycle in nature. We also got acquainted with the science of "Hydrology" and found out what it studies. We studied how the water cycle occurs in nature. Conducted experiments with rainwater and snow. And they came to the conclusion that puddles and snow contain bacteria. Therefore, you can’t take snow in your mouth and wet your hands in a puddle so that bacteria don’t get into our body. The hypothesis put forward by us at the beginning of our study was partially confirmed. We have learned that the water from the reservoirs and the earth rises in the form of steam under the influence of the sun's rays.

PROJECT MATRIX "Why it rains"

About the project:

Type
: research, subgroup (5 people) short-term: 2 weeks
Objective of the project:
expand children's understanding of the causes of rain
Project objectives:
- to teach a child to understand the relationship of phenomena in nature (sun-part-cloud-rain) - to expand knowledge about the properties of water, its various states (liquid, gaseous, solid) - the formation of the prerequisites for search activity, the creation of the necessary conditions for this with the help of an adult, and then independently - involving parents in participating in joint activities.
Project relevance
The propensity for research is characteristic of all children without exception. The child strives for knowledge, and the assimilation itself occurs through numerous “why”, “how”, “why”. For the guys in preschool age learnability, strength and depth of emotions and impressions are characteristic, therefore everything that is learned during this period turns out to be especially strong and serves as the basis for further learning and personal development. Subject- research activities develops and consolidates the cognitive attitude of the child to the world around him. One of the objects of attention of children in the group was such a natural phenomenon as rain. This was the reason for creating this project.

Expected Result:
-Children will acquire knowledge and understanding of natural phenomenon- rain - they will learn the concept of "water cycle in nature" - interest in research activities will increase - knowledge of the various states of water will expand - they will learn to carry out simple experiments with parents, and then independently - they will learn to plan the stages of their actions, analyze and draw conclusions
Equipment:
for experimentation: a kettle with boiling water, glass, cotton pads, a saucer. for practical activities: a fairy tale about the “Droplet” by Maria Shkurina, a poem for a physical education minute “Rain”, a fairy tale by Gianni Rodari “The Sun and a Cloud”. for artistic creativity: Gouache, pencil, A4 sheet, brushes, napkins.

Stages:
The project implementation is designed for 2 weeks № Stages Goal Timeframe 1. Preparatory and design identification of the problem - why is it raining? - develop a project plan, involve parents in joint activities - determine the goals and objectives of the project - collect material on this topic (use of a dictionary, specialized literature, the Internet) - prepare equipment and create conditions for conducting experiments at home 08.10.14-13.10. 14 2. Practical - observing the rain - looking at pictures and illustrations about natural phenomena - Conducting a physical training minute "Rain" and learning the poem of the same name. - reading the fairy tale "The Sun and the Cloud" by Gianni Rodari - Reading the fairy tale "The Journey of a Droplet" by Maria Shkurina. - Drawing “It will rain soon” - Conducting an experiment in a group (cotton wool, water) - Conducting an experiment with parents (teapot, glass) - Creating a poster "The water cycle in nature" 13.10.14-20.10.14 results and evaluate them; View videos with experiments recorded in the group and at home. 20.10.14.- 22.10.14.

Analysis emotional state children involved in the project.
Children's interest in research activities increased, they were very surprised by the result of experimentation. Throughout the implementation of the project, all participants had a positive emotional mood; Children were happy to participate in various types of joint activities. The most joyful and long-awaited stage for children was watching videos with experiments made in the group, as well as at home.

Conclusions:
As a result of the work carried out with children, the goal set earlier was achieved. Children acquired knowledge and ideas about rain, learned the concept of “water cycle in nature”, expanded knowledge about the various states of water (learned that steam, ice, snow are also water), learned to conduct simple experiments, enriched the subject-developing environment of the group (in "center of knowledge" appeared a poster "the water cycle in nature").

WHY IT RAIN
Terentyeva Alexandra
MBOU "Uyar secondary school No. 3" city of Uyar, Krasnoyarsk Territory
Leader: Nepomnyashchaya R.V.

Summer is coming, which means that most of the precipitation will fall in the form of rain. I watched the rain many times in the summer and I had questions that I tried to answer in my research work. I'm really wondering why it's raining? How does water rise to the sky to fall to earth as rain? Why is rain different? Is it necessary to rain? Are there dangerous rains?

Water vapor, in contact with cold air, condenses and turns back into water. This is how rains come.

But not all rains are beneficial. There are rains that should not be on Earth. These are acid and radioactive rains. They appeared due to economic activity people, pollution environment.

Rain is also good weather!

Purpose of the work: to learn as much as possible

about this natural phenomenon.

Tasks: 1. Investigate the transformation of water into steam.

2.explain how steam becomes water again.

Research methods - experiments, observations.

Place of study: school laboratory, home

Object of study: natural phenomenon - rain

II. DESCRIPTION OF THE MATERIAL COLLECTION METHOD AND MATERIAL PROCESSING METHODS

In order to learn more about the amazing natural phenomenon - rain, I had to turn to different sources. mass media: dictionaries, TV, special literature. During the collection of material, I visited all the libraries of our microdistrict, remembered the properties of water. The most exciting for me were the experiments that I conducted with my parents at home.

RESULTS AND DISCUSSION

1. What is rain?

Rain is primarily water. Ozhegov's dictionary says that "Rain is precipitation in the form of water drops, jets. And in Dahl's dictionary that "Rain is water in drops or jets from the clouds."

Rain - Precipitation in the form of raindrops. How is rain formed? Evaporation of moisture from the earth and air, heating up, rises to great height. Moreover, the more they heat up, the higher they rise. But at high altitude, it's always cold. Humid warm air, having risen to such heights, rarely cools down and falls down like a shower of raindrops. Rain - variety precipitation, the condensation product of water vapor contained in the air, falling out of clouds in the form of liquid droplets. Raindrops are formed by the coalescence of tiny droplets formed during the condensation process. However, in this way, rain can form, falling from drop clouds, the intensity of which does not exceed 1-2 mm/hour. More intense rain falls from clouds made up of supercooled droplets and ice crystals. IN summer time they melt, passing through the warm layers of air and fall to the ground in the form of large raindrops.

2. How is it formed?

Why is it raining?

· How does water rise to the sky to fall to earth as rain?

There are many oceans and seas, rivers and streams, lakes, ponds and puddles on earth. The sun heats up the water. It evaporates, i.e. becomes a transparent and invisible vapor. This light steam, together with warm air, rises higher and higher from the earth - many kilometers up. It's always cold up there. warm steam above it touches the cold air, and from it tiny droplets of water, like dust, are formed. The droplets are still very small and light. Cold air drags them down warm air lifts them up again. So they move up and down above the ground until they merge into large drops.

But there are already so many drops that all together they turn into a large cloud. The wind picks up the clouds and blows them around the world. Clouds float above the earth until heavy drops, no longer able to hold on, rain down on the earth.

It's been raining. Until recently, there were puddles in the yard. But the sun came out and dried up the water. It again turned into steam in order to form a cloud high in the sky and spill on the earth as a blessed rain.

At home, we can observe the formation of rain. I have had this experience:

Required:

small saucepan

Metal cover

Gas stove

Experience progress:

1. Pour water into a saucepan, ask adults to put it on the stove.

2. When the water boils, cover the saucepan with a lid.

Result:

There are drops of water on the lid. Shake the lid and drops of "rain" fall.

This is because...

... that water vapor is released from boiling water. On a cold lid, it cools down and again turns into a liquid. This phenomenon is called condensation.

Conclusion: Water vapor, in contact with cold air, condenses and turns back into water. This is how rains come.

How steam becomes water again can be observed in the following experiments. Water boils in a saucepan, clouds of steam are visible. Let's bring a cold spoon to a jet of steam. First, it is covered with small droplets of water, and then the water will start to drip from it. Tiny drops of water merge together until they are large enough for us to see as a cloud of steam. The steam rises up and comes into contact with the cold surface of the spoon. Tiny droplets cool down, settle on a spoon, coalesce into larger droplets, and run off as water.

We can make it rain ourselves. Fill a saucepan with a handle with ice cubes and hold it over a large pot of boiling water. What will happen? Very humid hot air, saturated with steam, rises and heats the walls of the saucepan chilled with ice. This steam condenses, settling on its walls, merges into large drops and flows down. It's raining!

3. What are the rains

Rains are classified according to two main features: intensity and duration.

The heaviest rain is called a downpour. The smallest rain is drizzle. But there are, quite special, summer rains, short, cheerful. They go in an amazing way - from a clear sky, in the light bright sun! There are no clouds in the sky, only a light white haze hangs in the air.

This is water vapor. It fell into a cold stream of air low above the ground, turned into droplets of water, they began to quickly merge, grow heavier and fall to the ground in rare large drops.

It passes quickly, this rain

4. What kind of rain should not be on Earth

But not all rains are beneficial. There are rains that should not be on earth. These are acid and radioactive rains. They appeared due to the economic activities of people, environmental pollution.

acid rain

There are many substances in nature, among them there are acids. Due to environmental pollution, acids began to form high in the sky. Often they fall to the ground along with the rain. These are the so-called acid rain. Plants and all living things suffer from them, many buildings deteriorate, including ancient monuments.

radioactive rain

Radioactive fallout is one of the most dangerous consequences of human pollution of the atmosphere. They are dust and droplets of atmospheric moisture containing radioactive atoms.

Radiation destroys living cells, weakening the body's defense against various diseases.

5. Do you need rain?

What if it never rained?

If there were no rain, rivers, seas and lakes would dry up, grasses and trees would burn. This means that there would be no fish, birds, animals and humans.

Rain is the most important source for us.

IV. CONCLUSION

Investigating this natural phenomenon, I came to the conclusion that rain is one of the amazing phenomena that exists in nature. Only people should monitor the ecology of the Earth and then dangerous rains will not fall.

Description of experiments

(Experiments were carried out at home with the help of parents observing safety rules)
Experience #1 Squeeze a dry ball of water tightly. Then lower it into a saucer of water. The cotton ball will unfold and swell with water. Carefully lift the top of the cotton wool over the saucer. If there is enough water, drops will begin to fall in the saucer.
Liliana's story: Imagine that I have a small cloud in my hands, it is saturated with water. There was a lot of water. Our cloud has turned into a cloud, the droplets cannot stay in it and begin to fall. It's raining.
Cloud, cloud, what are you talking about?
The cloud answers "Rain". This is how rain appears.
Experience #2 Required: metal saucepan, metal lid, gas stove
The course of the experiment: 1. Pour water into a saucepan, ask adults to put it on the stove.2. When the water boils, cover the pot with a lid.
Result:
There are drops of water on the lid. Shake the lid and drops of "rain" fall. This is because water vapor is released from boiling water. On a cold lid, it cools down and again turns into a liquid (this is how the appearance of rain can be explained).
