(Slide "Solar System)

Ιv. Work on the lesson.

Now we are in the solar system. In her center, a split ball - the sun. The grilled substance emits light. Light from the Sun to the Earth goes 8 minutes. And on the aircraft to the Sun would have to fly for 15 years! The 9 planets rotate around the sun, one of them is our land. Which side the earth turns to the sun, there is a day, and on the opposite side of the Earth - the night.

Mark in the drawings, in which part of the Earth the day, and in what - the night (slide). Sign on the words "day" and "night" lines. And some guys, I complicated the task: they still need to draw the sun. Guess where it should be!

Check out. Explain how you reasoned. Raise your hand who completed without errors!

So the sun does not just shine to us, it creates a day. Would we live without the sun? Why? (The sun gives us light and heat. No plants, nor animals can live without it)

Look at the screen. Think why the day is not visible? (Slide: The sun appears - the stars go out in the sky). What do you think you can not see the stars in the afternoon?

Read, as they say about this in the textbook.

Answer the questions. What is the stars? (huge flaming balls)

Why do they seem small points?

Why does not the stars see the day?

Stars in the sky are a lot, and everything is impossible to remember. People combined individual stars in the constellation and gave them names.

Guess the riddle: What bucket do not drink, do not eat,

But just look at him? (bucket constellation Big Malar)

About this constellation ancient Greeks came up with a legend, Marina will tell you to you.

"" The king lived a long time ago, he had Daughter Callisto. She was very beautiful, more beautiful than the goddess itself. And then the gera was angry and turned his beauty into the ugly bear. The son of Callisto Arkas did not know about it, and almost shot a bear on the hunt. But the Almighty God Zeus saved her - grabbed the tail, pulled the sky and turned into the constellation. The tail has stretched out, and the stars of the bear turned out to be a taper. "

Play with the stars in the catch-up, the stars from the constellation of the big bear will be alone to flash, and you follow the eyes.

Did you like the game?

Now collect the ladle of the Big Males themselves: connect the lines of the stars on the card - remember, the bucket 7 bright stars.

Check if you did correctly.

V. Checking the learning of a new material.

Now let's return from space, we will land and check that you remember. Offers recorded on the board, but they lack words. Futing words on cards. You need to return them to the place. I read the offer, and you finish it.

Stars are huge flaming ... (balls)

Day in the sky is not visible to the stars, because their light ... .. (immeasured at sun light)

Stars seem to us with small points, because they are .... (Far) from us.

The most closest star to Earth is .... (Sun)

Vι. Reflection.

Or can the sun be merry or sad? When?

Draw on one piece of cheerful, and on the other - sad sunshine.

We collect together our sun; Attach the funny sunshine here, if you were interested in the lesson, sad - if you missed.

What else would you like to know in the lessons?

Vιι. Homework.

Comments. The definition of learning themes of the lesson is carried out in accordance with the peculiarities of perception and psychology of younger school age.

What is the sun?

Without which plants and animals cannot live?

Without the sun, there would be no life on earth. It warms and illuminates the land. This understood more ancient people and worshiped the sun as God. They thanked him for the warmth. What rules do you know when sunbathing in the sun?

What is the sun? On p.32 Read about the sun? (Nearest star to Earth)

El. Appendix (Demonstration, Fragment of the Sun).

The sun is a huge flaming ball. The sun is a Giant Bowl, 109 more land. Our planet in comparison with the sun, like a pea next to a soccer ball. But it seems to us a small circle, because it is from the ground at a very long distance: 150 million km. Therefore, the sun's rays are not burned, but only warming our planet. And the Earth rotates around the Sun, putting it alone, then the other side. How sideways to the sun turns, there and day, on back side Earth - night. (Demonstrate ontelluria).

Output: So, the sun is not just shining in the afternoon, it creates a day for us. When the Sun illuminates the Earth, the day begins, and the night comes on the back of the earth.

Comments. The use of a video detection from an electronic application contributes to the activation of mental activity. Visuality (soccer ball and pea, tellurium) at this stage of the lesson is the most important reception that helps to learn the new material.

What is the stars?

Riddle: crumbled by night grain.

We looked in the morning - there is nothing. (Stars)

In the old days, people thought that stars were shiny lanterns suspended to the crystal silence. But it is not. Who knows what stars are? (Responses of children reading a well-reading student textbook textbook on p. 32)

In the textbook on p. 32 Read what stars are. What do you think, why don't we see the day of the stars?

In the afternoon, the weak shine of other distant stars is noticeable. And only at night when there are no sun, they are visible.

On page 32 of the textbook, consider the stars and read their names: Regulation, Sirius, Sun, Aldebaran. (Name to attach to the board)

Sunrise and sunset

The sun is a huge flaming ball. The temperature on the surface of the Sun is 20 million degrees. The sun is very large. It is 109 times more land. Sun - Ball Giant. It seems to us a small circle only because it is located from the ground at a very long distance.

If you put the sun next to the earth, then it would look like a big soccer ball next to the skiing.

From the ground to the Sun 150 million km. Therefore, the sun's rays are not burned, but only warmed and illuminate our planet. Without the sun, there would be no life on earth.

Plants, animals and people live only because life gives the sun. This understood more ancient people and worshiped the sun, like God. They thanked him for the heat and welcomed his sunrise in the morning.

The sun is the closest star to the ground, this is the center solar system. Our planet Earth is one of the nine planets of the solar system.

Stars - huge hot balls, similar to the sun. Many of them are much more Sun.. Stars are very far from the ground and therefore do not warm, and seem very small.

At the night sky, stars flicker with different colors: blue, white, yellow, red. White and blue stars are very hot. They are hot sun. Yellow - colder than whites. They are like our sun. Stars of reddish color is colder than the sun.

According to its sizes, the stars are very different from each other: there are red giants, normal stars and white dwarfs.

Stars in the sky a lot. And to figure them out, people united them into constellations. Constellations and brightest stars people gave names.

The constellation is a big bear.

Quiz. What is the stars? What is the sun? What creates the sun? Why don't other stars visible during the day? Who studies the stars? With what astronomer studies the stars? What is the constellation from?

Moon at night in the sky one golden orange. We passed two weeks, we did not eat orange, but only an orange slices remained in the sky.

Phases of the moon are still in antiquity people noticed that the moon changes his shape all the time. It looks like a round plate, then on the sickle, which was called the month. People could not explain this phenomenon and came up with fairy tales, legends, myths.

On the moon you can see dark and light spots. Light is the lunar seas in which there is not a drop of water. Dark spots are smooth areas (plains).

On the moon, the lunar craters are visible everywhere, which were formed from shots of meteorites - stones fallen from space. The entire surface of the moon is covered with a thick layer of dust. On her surface in the afternoon there is a heat up to 130 degrees, and at night - frost -170 degrees.

The moon is moving around the Earth and bypassing it around once a month. Therefore, the moon is called the natural satellite of the Earth.

Lunohodes for the study of the moon, people are sent to the moon moonwalks. They manage from the land on the radio.

People on the moon
