Rainbow

The word "rainbow" is similar to the word "joy". And in fact, it is joyful when suddenly an amazingly beautiful arc appears in the sky. In the old days they called it “Paradise Arc” and believed that it brings happiness. Since then, that’s what they call it – rainbow.

During the classes

1. Organizational moment.

Guys, we have guests at our lesson today. Let's turn around and say hello.

Let's check readiness for the lesson: textbook, workbook, envelope No. 1 - 1 pc., envelope No. 2 - 2 pcs., signals, colored pencils.

Listen to the motto of our lesson.

The bell has rung for us!

Do you agree with these words? Then get to work.

2. Updating knowledge.

Let's start our lesson by reviewing the material we have learned. Let's play the game “Believe it or not.” To work, we need signals - red and green. I will read the statements. If it is correct, you raise a green signal; if the statement is incorrect, then you raise a red signal. Slide 2

1. The Sun is the closest star to Earth.
2. The moon is a planet
3. There is air on the moon.
4. Wind is the movement of air.
5. Cold air is lighter than warm air.
6. The ear is the organ of hearing.
7. Sound travels as a wave.
8. The echo appears when a strong wind blows.
9. Loud sound is harmful to the ears.
10. A cloud is smoke.
11. The insect makes a buzzing sound.
12. It rains from a cloud because the water droplets in it are heavy.

Well done! You made me happy with your good answers.

3. Announcing the topic of the lesson.

And our lesson will continue with a fairy tale that will help us determine the topic of the lesson.

Author: One day Question Ant got caught in heavy rain and hid under a leaf. And when the rain almost stopped and the sun appeared, Ant heard someone singing in a thin voice high in the sky:

Sunny bunny.

I am always friendly with the light.
If the sun is in the window,
I'm from the mirror, from the puddle
I run through the leaves.

Ant: Who are you?

Ant: What are you doing up there, so high?

Sunny bunny: I do miracles!

Ant:

What a miracle - beauty!
painted gate
Showed up on the way
You can't drive into them or enter them.

Ant: How so? - I was surprised - You, the Sunny Bunny, are white, and the rainbow is multi-colored! Why is the rainbow multicolored?

The Sunny Bunny laughed and said nothing.

Teacher. Guys, what question do you think we will be looking for the answer to today?

Lesson topic: “Why is the rainbow multi-colored?” Slide 3

4. Setting the educational task.

Yes, guys, today we will talk about rainbows.

What would you like to know about rainbows? (Children's assumptions).

The ant suggests conducting research and finding out: (the teacher hangs up cards with questions, Annex 1).

What does the word rainbow mean?

How and when does it appear?

Why is the rainbow multicolored?

How to get a rainbow at home?

What colors does a rainbow consist of?

The tasks are clear to us, let's get to work.

4. Studying new material. Solving a problem situation.

Raise your hand, those who have seen a rainbow?

Where have you seen a rainbow? What feelings did you experience at this time?

Where did the word rainbow come from? The speaker will tell us. Listen carefully. Slide 4

What was the name of the rainbow in the old days? What did people believe?

What time of year can you see a rainbow?

After what natural phenomenon can a rainbow be observed? (After the rain)

The next speaker knows how and when a rainbow appears. Let's listen to her message.

6. Continued study of new material.

Where does color come from? After all, the sun's rays and raindrops have no color. Why did such a miracle appear in the air? Slide 6

Let's conduct a study on “Passage of a ray of light through a glass prism.”

1. On the slide we see a beam of light that is directed at the prism.

A prism is a transparent glass that replaces a drop of water.

This way you can get a small rainbow.

How did the rainbow turn out? (A ray of light passed through a prism and split into colored rays.)

What did the prism replace for us? (A drop of water)

2. Now we will look at the rainbow using a special device that resembles binoculars.

What is the gap for? (For a light beam. You can look through the slit)

What do you think is inside? (Glass lens replacing water droplets)

Looking at a rainbow (device for 3 desks) – 3-5 min

Guys, who is the main “artist” in nature? (Sun)

Where do the sun's rays hit in the sky? (On the raindrops)

What happens to the sun's rays? (Disintegrate into multi-colored rays.)

What is formed in this case? (Rainbow).

Well done! You're right. The rainbow was built by the sun's rays and raindrops.

What is a rainbow? (This is solar glow. The sun's rays, falling on a drop of rain, break up into multi-colored rays.)

Let's read the conclusion in the textbook.

(Reading the explanation of the Wise Turtle from the textbook. Page 31)

Let's listen to a poem about a rainbow.

Reading a poem

The summer rain has passed since the morning,
The sun came out.
The child was surprised
Looking out the window, -
Seven-color arc
Covered by clouds.

What did the poetess name the rainbow in the poem? (Seven-color arc)

When we look at a rainbow from the ground, it appears to us as an arc. If you look at a rainbow from a height, such as from an airplane, it will appear to be a circle. Slide 7, 8

How many colors does the rainbow have? (seven) Maybe someone already knows the order of the colors in the rainbow? Let's check by collecting a picture from puzzles.

Work in pairs. (envelopes No. 1 with puzzles, Appendix 5) Slide 9

What color does the outside of the arc create? Which one is inside? What color comes next to red? Orange? Yellow? Green? Blue? Blue? Which arc will be the longest? The shortest?

How to remember them in order and very quickly?

To remember the colors of the rainbow, people came up with this phrase - a hint:

“Every Hunter Wants to Know Where the Pheasant Sits” Slide 10

How can these strange words help?

The first letters of these words determine the color order.

Let's learn the order of the colors of the rainbow.

Work in pairs.

(learning memorization) textbook - p. 40

Examination. Slide 11

7. Consolidation of what has been learned.

The poem “Colors of the Rainbow” (author A. Wenger, Appendix 6).

Let's check how you remember the colors.

Game “What has changed?” (change 2 colors, remove one color, name the colors in order, restore the rainbow)

8. Physical education minute. Game “Build a Rainbow”.

(2 teams participate. Each student has a rainbow scarf around his neck

one of the seven colors of the rainbow. Which team will build the rainbow faster?)

9. Consolidation of the studied material.

Textbook – p. 41

Look what Ant and Wise Turtle are doing? (they decided to make a rainbow themselves)

Can they get a rainbow?

Why? (The sun's rays will pass through the water drops and a rainbow will form.)

What rule should you remember? Slide 12

(To see a rainbow, you must be strictly between the sun (it should be at the back) and rain (he should be in front of you).)

Additional Information(Appendix 7)

Working in a workbook.

We'll help you color it correctly. We will draw a rainbow in the workbook - p. 26 She will be bright and beautiful. But what color should you start with? (work on ESM)

– Let’s say the memorization in chorus again.

Color it yourself

(close the EOR slide, play the song “Rainbow”).

Mutual testing - work in pairs (open EOR slide).

Individual work at the board

10. Test of knowledge. Slide 13 (envelope No. 2, Appendix 8)

Now let's play the game “Third extra " Of the three named colors, you must cross out the color that is not in the rainbow, let's check your knowledge on the slide.

• Orange, brown, yellow;
• Green, blue, white;
• Violet, crimson, red;

Well done! What rainbow color isn't here?

11. Homework:

1. Color the trailers in your workbook.

Presentation for a lesson on the surrounding world in 1st grade Why is the rainbow multi-colored?

Guess the riddle Colored rocker hanging over the river

What is a rainbow? It happens like this: the rain has just stopped or is still noisy, but the clouds are already beginning to part, the blue sky is peeking between them and the sun is appearing.

At this moment, a beautiful picture appears in the sky: a multicolored rainbow covers the vault of heaven with a wide ribbon. Sometimes two rainbows appear at once.

How is a rainbow formed? The sun's rays, falling on raindrops in the sky, break up into multi-colored rays. This is how a rainbow appears.

What color is the rainbow? There are seven colors in the rainbow, and they are all always in the same order: red, orange, yellow, green, blue, indigo, violet. To remember the sequence of colors of the rainbow, they came up with the following phrase based on the first letters of the color names: Every hunter wants to know where the pheasant sits.

Rainbow The word "rainbow" is similar to the word "joy". And in fact, it is joyful when suddenly an amazingly beautiful arc appears in the sky. In the old days they called it “Paradise Arc” and believed that it brings happiness. Since then, that’s what they call it – rainbow. A rainbow only appears if it rains and the sun shines at the same time.

Check yourself! 1. How does a rainbow appear? 2. What phrase can tell us the sequence of colors of the rainbow? 3. List the colors of the rainbow using a clue phrase?

(Children mark the names of colors with letters.)

Teacher ( reads a poem).

Someone built it in the meadow.
The master tried
He took some paint for the gates
Not one, not two, not three -
As many as seven, look.
What is this gate called? (Rainbow.)

-Can you draw them? (Yes.)

14. There are a lot of poems dedicated to the rainbow, let’s tell them.

There is rain and thunder in the sky,
Close your eyes!
The rain has passed, the grass is shining,
There is a rainbow in the sky.
Hurry up, hurry up
Run out the door
Barefoot on the grass,
Jump straight into the sky.
(S. Marshak)

The sun is shining and laughing,
And the rain pours on the ground.
And goes out into the meadows
Seven-color arc.
(N. Mikhailova)

Warm May day
Drummer Thunder
Like a hammer
Hit the cloud: “Bom!”
A cloud of rain is pouring,
The wind rubs the paint
And draws RA-
And draws DU-
And draws GU.
Rainbow!

Multi-colored ribbons
hover above the ground,
Amazed people
looking to the heavens.

The rainbow spread
smooth semicircle
Festive halo
suddenly opened.

Multi-colored miracle
mystery of the Earth,
Unanswerable miracle
in solar dust.

A splash of fabulous sparkles,
washed by the rain.
Rainbow over the cloud
the flower bed took off.

Rainbow washed
seen in the distance.
Marvelous rocker
on the shoulders of the Earth.
(V. Musatov)
