The rain will pass and now a beautiful rainbow has appeared in the sky. You can also see a rainbow above the fountain, near the sprinkler, and if you try and stock up on the necessary supplies, you can make a rainbow yourself at home!

I remember very well when I went to a drawing class as a child, they brought us a triangular glass prism and showed us magical transformation ray of light. A white ray of light, passing through the edges of a prism, breaks up into all the colors of the rainbow. We don’t have a triangular glass prism at home yet, so we use earrings with stones and crystal pendants from a chandelier to make small rainbows.

There is another very simple item that will help you make a rainbow on your wall at home. Don't believe me? Check it out!

Decomposition of white light into a spectrum using a disk

Take:

old CDs,
white paper
flashlight,
It would be nice if it was a sunny day.

We played with the rainbow for a long time, and then the sun hid behind a cloud, then a flashlight came in handy. Only the flashlight made the rainbow less bright.

At the beginning, I wrote that a ray of light, passing through a triangular prism, breaks up into seven colors of the rainbow. The mirror surface of the disc is made of plastic, on which there are numerous grooves. These grooves act like many small prisms placed in a circle. Therefore, when light hits the disk, a rainbow is formed.

Sometimes a rainbow is formed completely by accident, and sometimes you need tools to get it. One day I was drinking tea, and a ray of light, having entered the glass, turned into bright rainbow on the wall. But this happened only once: scratch: There was another case when we studied the refraction of a ray of light in water, a rainbow was formed using a transparent plate, filled with water .

If you and your child start studying the rainbow, don’t forget to add riddles about this wonderful thing to the lesson. a natural phenomenon.

Color the world around bright colors- you are quite capable. Today we told you how to make a rainbow at home and give your children a lot of positive emotions. Now each of your rooms can have seven colors of the rainbow. Have you played with light? It's time to turn the page and continue an amusing trip into the world of science. I have a GIFT for you. A collection of entertaining experiments with sound. Let science be not only bright for you, but also ringing. See you soon on the pages of Gay Science.

Happy experimenting! Science is fun!

Did your child once get excited about seeing a rainbow? She was like magic manifested! But does he realize that he can make a rainbow himself right at home? After conducting this fun and colorful experiment, your child will be pleasantly surprised at how easy and simple it is to create such magic. It is enough to use only a few ordinary household items... and the nature of this colorful atmospheric phenomenon will become closer and clearer to him.

What you will need for this:

a glass of water (about three-quarters full);
White paper;
sunny day.

Procedure:

1. Fill a glass about three-quarters full with water and take a sheet of white paper.

2. Then ask your child to bring them to the window. You can also go to another place that also has sunlight.

4. Draw the child’s attention to how sunlight passes through a glass of water, refracts (bends) and forms a multi-colored image on a sheet of paper. So how? Happened?

5. Now invite your child to continue the experiment. Let him try holding a glass of water at different distances from the paper and at different angles to it. What were the results? Has the effect changed?

What's happening?

And although we usually see a rainbow in the sky as a colored arc, it can form in other places. You may have seen a rainbow in a fountain or in the mist of a waterfall. And by completing this experiment, you managed to get your own little rainbow right at home.

Rainbows form because sunlight is refracted (bent) as it passes through raindrops. The same thing happens when sunlight passes through a glass of water. It refracts, separating into red, orange, yellow, green, blue, indigo and violet. These colors are called spectrum colors.

The most interesting thing is that when the beam of light just aimed at a glass of water and all the colors of the spectrum were collected together, the beam was white. And only passing through a transparent barrier (drops of water or glass), it disintegrated from white into seven different colors.

But why did it fall apart? And all because light consists of electromagnetic waves of different lengths. The shortest waves are red, have the least energy and therefore refract less. But the longest waves are violet, which means they have a lot of energy and are refracted more. You will notice that these colors tend to be at different ends of the rainbow. The remaining colors have an intermediate wavelength and are located in the middle.

RESEARCH WORK “HOW TO CREATE HAPPINESS AT HOME?”

Purpose of the study: to determine what connection exists between rain, sun and the appearance of a rainbow, and whether it is possible to get a rainbow at home. Object of study: natural phenomenon R A D U G A. Subject of study: origin of the rainbow. Research problem: how to create a rainbow at home; how a rainbow appears and why it is multi-colored; how to create White color from colored components.

RESEARCH OBJECTIVES How does a rainbow appear? When does a rainbow appear? Is it possible to get a rainbow at home? How to get white from colored components?

HYPOTHESES Suppose that a rainbow appears in sunny weather during rain, when the sun's rays pass through raindrops. Suppose that a rainbow can be obtained by replacing the sun's rays with an artificial light source.

BASIC METHODS Studying literature. Observation. Experiment.

“Every hunter wants to know where the pheasant is sitting.” “How once Jean the bell-ringer knocked down a lantern with his head.”

Every schoolchild can repeat Newton's experiment. I repeated this experiment, but with an artificial light source. We observed the decomposition of light into a spectrum when passing through a prism at home, using a prism and a projector. To do this, we “caught” a white beam with a prism and got an image of a rainbow on the wall. The light, which seemed white, played on the wall with all the colors of the rainbow. This is how we penetrated the mystery of the ray, which the famous English scientist penetrated more than 300 years ago.

HOW DOES R A D U G APPEAR? When it rains, there is a huge amount of water droplets in the air. Each droplet plays the role of a tiny prism, and since there are so many of them, the rainbow turns out to be half the sky. This is who turns out to be building multi-colored gates in the sky quickly and beautifully! Ray of sun and raindrops. All rainbows are sunlight that passes through raindrops, as if through prisms, is refracted and reflected on the opposite side of the sky.

WHEN DOES THE RAD UG APPEAR? A rainbow appears only when the sun peeks out from behind the clouds and only in the direction opposite to the sun. A rainbow occurs when the sun illuminates a curtain of rain. Rainbows can only be observed early in the morning or late in the evening.

DOES IT HAPPEN WITHOUT RAIN? Such a miracle also happens.

EXPERIENCE “CREATION OF RAINBOW AT HOME” To make sure that white color consists of seven colors and a rainbow can be obtained artificially, we conducted an experiment. We needed: a flashlight, a water container, a flat mirror, white cardboard and water. Progress of the experiment: Filled the tray with water. Placed a mirror with an angle. We directed the light of a flashlight onto the part of the mirror immersed in water. To catch the reflected (or refracted) rays, they placed cardboard in front of the mirror.

AS A RESULT, A REFLECTION OF ALL THE COLORS OF THE RAINBOW APPEARED ON THE CARDBOARD, WE WERE ABLE TO GET THE RAINBOW IN “HOME” CONDITIONS. Conclusion: a beam of light reflected by a mirror at the exit from the water is refracted. The colors that make up white have different angles refraction, so they fall into different points and become visible.

EXPERIENCE “HOW TO OBTAIN WHITE COLOR FROM COLOR COMPONENTS?” Just like we decomposed the white color into its components, you can get back the white color from the colored components. If seven colored light sources are placed on one side of the prism at appropriate angles, we will get a white beam at the exit from it.

It is difficult to do such an experiment on your own, but there is another way. If you take a white circle and paint it in the seven colors of the rainbow, and then put this circle on an axis. And start rotating it quickly, in place of the colored circle, we will see white. This occurs due to the inertia of human vision. The eye cannot see each color separately on a rapidly rotating circle, and for it they all merge into one white color.

CONCLUSION As a result of the work done, we were convinced that the prism can turn a white beam into a seven-color, rainbow one. They found out that raindrops and ice crystals can divide the white color into seven colors, so you can see rainbows in autumn, summer, spring, and winter. But there are conditions under which such an amazing natural phenomenon can be seen. We got acquainted with ways to obtain a rainbow at home, creating white from colored components.

Hello! I, Antipenko Sergey, student of grade 1 “b” of school No. 19

G. Izobilny. And this is my supervisor, Marina Nikolaevna Meshalkina.

Let me introduce my research work“How to create a rainbow at home?”

Every person at least once in his life admired a natural miracle - a rainbow. Many people have probably noticed that rainbows usually appear after rain. I have seen a rainbow many times, and this phenomenon always delighted me. Last summer my parents and I walked around the city. The weather was sunny, but suddenly it started raining: warm, lightly drizzling. It stopped as quickly as it started, and literally immediately we all saw a rainbow in the sky. I wanted to know what a rainbow is and how it appears.

Purpose of the study: to determine what the connection is between rain, sun and the appearance of a rainbow, and whether it is possible to get a rainbow at home.

The object of study is the natural phenomenon of the rainbow.

The subject of the study is the origin of the rainbow.

Research problem:

how to create a rainbow at home;
how a rainbow appears and why it is multi-colored;
how to create white from colored components.

Research objectives:

How does a rainbow appear?
When does a rainbow appear?
Is it possible to get a rainbow at home?
How to get white from colored components?

Hypotheses put forward:

Suppose a rainbow appears in sunny weather during rain, when the sun's rays pass through the raindrops.
Suppose that a rainbow can be obtained by replacing the sun's rays with an artificial light source.

Basic methods: literature study, observation, experiment.

There is probably no person who does not admire the rainbow. This magnificent colorful phenomenon in the sky has long attracted everyone's attention.We all know the saying from childhood: “Every hunter wants to know where the pheasant sits,” there is also a less popular version: “How once Jean the bell-ringer knocked down a lantern with his head.” Using the initial letters of these sayings, we remember the names and sequence of colors of such an unusual and beautiful natural phenomenon as a rainbow.

Why does she appear so beautiful, and even color painting in the air? We looked for an answer to this question in additional literature. Here's what we learned.

Sunlight or regular beam white light is actually a combination of all colors. When a beam of light moves through air, almost nothing happens to it, but if a transparent substance noticeably different in density from air gets in its way, interesting things begin to happen to the light. When light hits the boundary of such a substance, it is deflected, but the most important thing is that each of its components deflects differently.

Isaac Newton proved that ordinary white color is a mixture of rays different color. “I darkened my room,” he wrote, “and made a very small hole in the shutter to let in the sunlight.” In the path of the sun's ray, the scientist placed a special triangular piece of glass - a prism. On the opposite wall he saw a multi-colored strip - a spectrum. Newton explained this by saying that the prism decomposed the white color into its component colors. Newton was the first to realize that the sun's rays are multicolored.

To do this, we “caught” a white beam with a prism and got an image of a rainbow on the wall. The light, which seemed white, played on the wall with all the colors of the rainbow (these multi-colored, bright stripes are called the solar spectrum). This is how we penetrated the secret of the ray, which the famous English scientist penetrated 300 years ago.

We looked at white objects through a prism, they looked colorful, rainbow-colored. Rainbow is the most famous, well-known spectrum.

So, for a rainbow to appear, a ray of sunlight must fly through a prism? But there are no prisms in the sky! How then does a rainbow appear?

2.2. How does a rainbow appear?

There is nothing strange here. A rainbow is simple, it is the sun's rays refracting in raindrops. When it rains, there is a huge amount of water droplets in the air. Each droplet plays the role of a tiny prism, and since there are so many of them, the rainbow turns out to be half the sky. This is who turns out to be building multi-colored gates in the sky quickly and beautifully! Ray of sun and raindrops. All rainbows are sunlight that passes through raindrops, as if through prisms, is refracted and reflected on the opposite side of the sky. The outer edge of the arc is usually red, and the inner edge is purple. There are seven colors in the solar spectrum: red, orange, yellow, green, blue, indigo and violet.

Conclusion: A rainbow appears in sunny weather during rain, when the sun's rays pass through raindrops.

2.3. When the rainbow appears

Then the question arises: why don’t we always see a rainbow when it’s raining or sunny?

A rainbow appears only when the sun peeks out from behind the clouds and only in the direction opposite to the sun.
A rainbow occurs when the sun illuminates a curtain of rain.

You need to be strictly between the sun (it should be behind you) and the rain (it should be in front of you). Otherwise you won't be able to see the rainbow! The sun, our eyes and the center of the rainbow should be on the same line! If the sun is high in the sky, then it is impossible to draw such a straight line. This is why rainbows can only be seen early in the morning or late afternoon. A rainbow appears provided that the angular height of the sun above the horizon does not exceed 42 degrees.

Can there be a rainbow without rain?

It turns out that such a miracle also happens. In winter, ice crystals “float” in the air. They can also divide white into the seven colors of the rainbow, so rainbows can be seen even in winter. The air, although it seems absolutely transparent, actually also decomposes light into its component colors. Noticeable - this happens at sunrise or sunset. Passing through the thickness of the earth's atmosphere, its rays bend a little, and as we remember, the red color bends weaker than others. It is for this reason that the sun, being close to the horizon, acquires a red tint. Rays of a different color bow out more strongly and no longer reach us.

Experience “Creating a rainbow at home”

To make sure that the white color consists of seven colors and the rainbow can be obtained artificially, we carried out experience.

We needed a flashlight, a water container, a flat mirror, white cardboard and water. Progress of the experiment:

Filled the tray with water
They installed a tilting mirror.
We directed the light of a flashlight onto the part of the mirror immersed in water.
To catch the reflected (or refracted) rays, they placed cardboard in front of the mirror.

As a result, a reflection of all the colors of the rainbow appeared on the cardboard; we were able to get a rainbow in “home” conditions.

Conclusion: a beam of light reflected by a mirror at the exit from the water is refracted. The colors that make up white have different angles of refraction, so they fall at different points and become visible.

Experiment “How to get white from colored components?”

Just like we decomposed the white color into its components, you can get back the white color from the colored components. If seven colored light sources are placed on one side of the prism at appropriate angles, we will get a white beam at the exit from it.

4.CONCLUSION

As a result of the work done, we convinced that the prism can turn a white beam into a seven-color, rainbow one. Found out that raindrops and ice crystals can divide white into seven colors, so you can see a rainbow in autumn, summer, spring, and winter. But there are conditions under which such an amazing natural phenomenon can be seen. We met with methods for producing a rainbow at home, creating white from colored components.

In conclusion, I would like to thank my supervisor, Marina Nikolaevna Meshalkina, for the assistance provided to me during my work.

Thank you for your attention!

Lesson summary “Rainbow at home”

Rainbow at home.

Purpose of the study: define what it is rainbow how is it formed, and is it possible to obtain rainbow at home.

Research objectives:

1. Find out where it comes from rainbow.

2. Determine what they are rainbows.

3. Try to get rainbow at home.

Progress of the lesson:

1. What is rainbow?

Rainbow- modified word "raiduga", or God's arc.

(According to V. Dahl's dictionary)

Rainbow- a multi-colored arc-shaped stripe on the firmament,

formed due to the refraction of sunlight in raindrops.

(Explanatory dictionary of the Russian language by Ozhegova S.I.)

Both ancient people and ancient scientists tried to unravel the cause of its occurrence. 2. How is it formed? rainbow?

Sunlight appears white to us. But in fact it consists of several colors. It happens that when it rains, the sun comes out, and then the sunlight passes through the water droplets and "disintegrates" for several colors. There are always seven of these colors, and they are arranged in strict order. Red, orange, yellow, green, blue, indigo, violet. So it turns out multi-colored rainbow. An object that can split a ray of light into its components is called "prism". The resulting colors create a strip of colored lines called "range". Rainbow and there is a large spectrum, or band of colored lines, resulting from the decay of a ray of light passing through raindrops. IN in this case raindrops act as a prism.

Rainbow appears, only when the sun peeked out from behind the clouds and only in the direction opposite to the sun.

Rainbow appears when the sun illuminates the curtain of rain. You need to be strictly between the sun (it should be at the back) and rain (he should be in front of you). Otherwise can't see the rainbow!

The sun, our eyes and center rainbows must be on the same line! If the sun is high in the sky, then it is impossible to draw such a straight line. That's why rainbow can only be observed early in the morning or late in the evening. Rainbow appears under condition that the angular height of the sun above the horizon does not exceed 42 degrees.

Does it happen? rainbow without rain?

It turns out that such a miracle also happens. In the air in winter "float" ice crystals. They can also divide white into seven colors rainbows, That's why rainbow can be observed even in winter.

How to do rainbow at home?

Experiment No. 1.

Target: receiving rainbows at home using a CD.

Equipment: CD, light source - sunbeam.

Description of the experiment: A computer disk caught a ray of sunlight and directed it to the wall and ceiling of the room. It turned out rainbow.

Experiment No. 2.

Target: receiving rainbows at home using napkins, water and markers.

Equipment: a plate of water, napkins and markers.

Draw circles on a napkin using felt-tip pens of different colors. Pour enough water into the plate to cover the bottom. Place a napkin in the water and watch the miracle!

Experiment No. 3.

Target: receiving rainbows at home with candy and water.

Equipment: plate, water, MMDEMS

Put the candies in the circle in order rainbow colors, pour into the middle of the plate plain water and enjoy the process. After a few seconds, the child clearly understands what the dye is.

Experiment No. 4.

Target: receiving rainbows at home using a mirror and a flashlight.

Equipment: a plate filled with water, white cardboard, a mirror, a light source - a flashlight.

Description of the experiment: We took a plate, filled it with water, and lowered the mirror at an angle. Then they directed the light of the flashlight onto the part of the mirror immersed in water. When we placed white cardboard in front of a mirror to catch the reflected rays, we saw a reflection on the cardboard rainbows.
