What to make a rainbow from for crafts. How to make a voluminous pony rainbow dash from paper using a template with your own hands

It seems to us that the light is white. But in reality it consists of different colors. It happens that when it rains, the sun comes out, and then the sunlight is refracted in water droplets and “breaks up” into several colors. There are always seven of these colors, and they are arranged in a strict sequence: red - orange - yellow - green - blue - indigo - violet. This is how a beautiful multi-colored rainbow appears in the sky.

A how to make a rainbow at home? You don't have to wait for the rain to see this a natural phenomenon. It can also appear in splashes of water if you water plants in the garden on a bright sunny day.

All children love to draw a rainbow, depicting it with bright, rich colors:

However, in reality, the colors of the rainbow are continuous and smoothly transition from one to another. In reality, they change thousands of shades, which means there are many more than seven.

To admire the play of colors and shades, you can conduct experiments and get a rainbow at home.

Homemade rainbow experiments

I. Using sunlight

1. The easiest way

Wait for sunny weather. Take a glass of water and a sheet of white paper.

The sequence of your actions should be like this:

2. Method using a mirror and a flashlight

The experiment should be carried out in sunny weather. To carry it out, you need a bowl of water, a mirror, a flashlight and a sheet of white cardboard.

The actions are:

• Place the mirror in a shallow bowl of water as shown in the picture below;
• position the bowl so that a ray of light - from a flashlight or from the sun - is reflected from the mirror onto a sheet of white cardboard;
• change the angle of objects if necessary.

In the water, the light should refract and break up into colors, so that a small rainbow will be reflected on the cardboard:

Thus, thanks to sunlight, it is not difficult to obtain a rainbow. But is it possible to “arrange” it with the help of objects of method 2 in the dark?

II. Without using sunlight (in the dark)

So, we decided to conduct an experiment in the bathroom, in complete darkness, using only a flashlight.

We hoped for positive result, ideally something like this:

But these are expectations :)

The reality is not particularly impressive... Although you can see a circular rainbow. A beam of light from a flashlight reflected from the mirror onto the bathtub:

This is what the plot image looks like rainbow spectrum on the bath:

Overall, the experiment was a success.

Thus, making a rainbow at home is quite possible, even without sunlight. Which is what needed to be proven :)

Magic discs

By the way, there are other ways to get a rainbow at home, even without water. Instead of a mirror, an old CD is perfect for this purpose.

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 where there is also 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 under different angles To her. 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.

On a gloomy autumn day you just want to please yourself with something bright and unusual. You will be surprised, but sometimes colored paper can work wonders if you approach it creatively. So, let's begin. For the rainbow you will need seven colors of paper, scissors, cotton wool (it will make two cute clouds), a stapler, glue, silver beads and thread or fishing line.

First you need to cut seven strips of the same width, but slightly different in length (approximately 6-7 mm).

We fasten the strips with a stapler on one side.

Then we align the edges on the other side and get a rainbow blank.

Now you need to make clouds from cotton wool. The secret is to lightly wet your fingers with water and form two clouds that you glue to the ends of the rainbow.

Now it's the droplets' turn. We will cut them out of blue paper as shown in the photo. We will need three droplets.

At the bottom of the thread we attach a silver bead. Glue the three cut out droplets together, not forgetting to glue a thread in the middle.

That's it, our rainbow is ready. You can give it to someone, or you can just hang it on a chandelier or on a window and enjoy.

TOI came from a good fairy tale,
and got a little naughty?
Who mixed the colors in the sky,
and spilled it on the rainbow?
And now she's colored
Smiles from heaven
Calling passersby
Very strong interest!

Since childhood, each of us has been fascinated by such a wonderful natural phenomenon as a rainbow. Where does it come from? Can it be made at home? To answer these and other questions, we conducted a study, the goal of which was to make a rainbow at home.

Tasks, which we have set for ourselves:
Find out what a rainbow is and how it appears.
Learn about the myths and legends associated with rainbows.
Make a rainbow at home using scrap materials.

We suggested that a rainbow can be made at home and even without using water.

During the study, we analyzed literature and Internet sources on the topic, used our observations, and conducted a number of experiments.

Myths and legends about the rainbow
Rainbow is one of the most beautiful natural phenomena. A multi-colored arc that appears in the sky after rain on a sunny day attracts the attention of not only children, but also adults. Rainbows can be seen in the paintings of great artists. Rainbows are mentioned in poems and fairy tales. There are many myths associated with the appearance of a rainbow in the sky.
The ancient Greeks believed that the messenger of the gods, Iris, descended to people along a rainbow from heaven to earth. Iris was represented as a charming girl - beautiful and light, with two majestic rainbow wings behind her back. Having spread her wings wide, she is ready at any moment to take off and rush through the sky with the speed of a swallow, and the road along which she runs is a rainbow. Iris carried out the orders of Zeus and Hera and was considered a mediator between the gods and people.
The ancient Chinese thought that the rainbow was a heavenly dragon, which meant the unity of Heaven and Earth.
In Slavic myths and legends, the rainbow was considered a magical heavenly bridge from heaven to earth, a road along which angels descend from heaven to collect water from rivers. They pour this water into the clouds, and from there it pours out as life-giving rain.
However, not everyone believed that the appearance of a rainbow was good. Among some peoples, rainbows were considered a bad sign. The appearance of a rainbow meant someone's imminent demise. Along the rainbow, the souls of dead people move to the kingdom of the dead.

Folk signs

• A low and flat rainbow means bad weather, and a high and steep rainbow means a clear day.
• If the spectrum of the rainbow is dominated by red, then you need to wait for a strong wind.
• A low rainbow, the edges of which rest on bodies of water, portends bad weather.
• A bright rainbow - wait for bad weather.
• If there is more green color - there will be rain, yellow - good weather, red - wind and drought.
• A morning rainbow promises a cloudy day, and an evening rainbow promises a fine day. Rainbows are rare in winter and signal impending frost or snow.
• If a colored arc appears in the east, then expect good weather; if in the west, then expect rain.
• A rainbow along the river means heavy rain, and across it means clear weather.
• The rainbow is visible for a long time - there will be bad weather for several days.
• If a rainbow appears in the direction from which the wind is blowing, it will be a rainy day; if in the opposite direction, it will be a clear day.
• The rainbow is located from south to north - expect heavy rain, from west to east - sun.
• The appearance of a rainbow on Saturday promises a rainy next week.

How does a rainbow appear and why is it colorful?
Rainbows appear as a result of the interaction of light and water. When it rains, a huge number of water drops float in the air. Each drop acts as a tiny prism. The sun's rays, passing through raindrops, are refracted and break up into a spectrum that we call a rainbow.
There are seven colors in the rainbow: red, orange, yellow, green, blue, indigo and violet.
These colors in the rainbow were first proposed by the great English scientist Isaac Newton. At first he identified 5 colors, but then he thought and decided that there would be 7 colors, like 7 notes. In fact, the color spectrum is continuous, its colors smoothly transition into each other through many shades.
Prove that the colors of the spectrum add up and form White light You can use a regular computer disk, onto which you paste strips of red, orange, yellow, green, blue, blue, purple paper in a circle (in sectors), insert a pencil into the hole of the disk and spin the disk. As the rotation speed increases, the disk begins to appear white, or more accurately, greyish-white.
The brightness of the colors and the width of the rainbow depend on the size of the raindrops. The larger the drops, the narrower the brighter than the rainbow, there is more red in it rich color. If there is light rain, the rainbow turns out to be wide, but with faded orange and yellow edges.

Did you know that rainbows can happen even without rain?
Indeed, rainbows can be seen near lakes, waterfalls, and large rivers, where the rays of the sun are reflected from the water surface. You can also see a rainbow on a sunny, clear day near fountains, as well as when watering flowers in the garden with a hose (if you hold the hole of the hose with your fingers, creating a mist of water, and point the hose towards the sun).

Practical part (experiments)
Rainbow is a miracle of nature. Is it possible to create this miracle yourself, at home? I decided to try this and conducted several experiments. To make the rainbow bright, I carried out all the experiments in a dark room, using only light from table lamp. Here's what I got.

Experiment No. 1
When conducting the experiment, I used: a glass prism, a modeling board, a piece of plasticine, and a table lamp. Using plasticine, I attached the prism to the modeling board and directed a beam of light from the table lamp onto the prism.
Slightly changing the angle of the board, on the white wall opposite the ray of light, I saw this rainbow.

Experiment No. 2
I used: rectangular tray, plain water, mirror, table lamp. I poured some water into the tray and lowered the mirror into it at a slight angle. The beam of light from the lamp was directed onto the part of the mirror immersed in water.
By adjusting the tilt of the mirror, I got this rainbow on the ceiling.

Experiment No. 3
I used: a computer disk, a table lamp. I directed a beam of light from a table lamp onto a computer disk and reflected this beam onto the ceiling, on which I got such a beautiful rainbow!

Experiment No. 4
I used: a tray, a large plastic bubble ring, soapy water. I placed a plastic ring in a tray of soapy water, then carefully took it out - a film had formed inside the ring. Turning the ring towards the light, I saw these rainbow stripes on the film.

Experiment No. 5
I poured some water into a transparent glass glass and placed it on the table. Looking at the glass of water from the side (the glass should be at face level), I saw a barely noticeable rainbow above the surface of the water. I decided to shine a beam of light from a flashlight onto a glass of water, the rainbow became clearer and brighter.

The experiments have proven that it is very easy to make a rainbow yourself at home, using a beam of light from an ordinary table lamp or flashlight instead of sunlight.
In the course of research and experimentation, I decided to try to make a “Rainbow Box” from computer disks, which could be used to decorate rooms during home parties or classroom discos. My dad helped me make the rainbow box. We found several old computer disks at home and carefully covered a small area with them on all sides. cardboard box. They made a hole in one of the corners, threaded a ribbon through it and hung the “Rainbow Box” from the ceiling.

By shining a flashlight on the box, we created a beautiful rainbow lighting in the room, which delighted all my friends and helped make my house party more fun and modern!
