00:00:13

hello guys, I'm glad to meet

00:00:16

you at the science lesson, the topic of the lesson is

00:00:20

how the earth rotates. Today in the lesson you

00:00:25

will repeat previously studied material about the

00:00:28

solar system, consolidate your knowledge about the

00:00:32

change of day and night and the change of seasons,

00:00:36

learn what theories are and expand your

00:00:40

knowledge about the movement of the earth around its axis

00:00:44

and the sun is no secret that the

00:00:48

work of the brain is directly related to the work of

00:00:51

the hands, start a lesson on starting the brain

00:00:55

with finger gymnastics, make sure that

00:00:58

the movements are correct, gain

00:01:00

speed, our lesson will be held under

00:01:04

the motto:

00:01:05

our goal is to give a new impetus to the development of

00:01:09

science to set the right direction for

00:01:12

science

00:01:13

these words belong to Nursultan

00:01:16

Abishevich Nazarbayev young astronomers

00:01:20

today we continue to travel through the

00:01:23

starry universe

00:01:24

we have a lot to learn why

00:01:28

day and night alternate on earth why one

00:01:32

season gives way to another why we

00:01:35

need good knowledge intelligence and ingenuity the

00:01:38

ability to observe and analyze and

00:01:41

of course be disciplined

00:01:44

Let's go on a long interesting journey

00:01:49

Guess the riddle You warm the whole world

00:01:53

and don't know fatigue

00:01:57

You smile at the window And your name is all

00:02:02

the sun guys What do you know about the sun

00:02:07

The sun is a star It's a huge hot

00:02:12

gas ball Does the sun stand still No

00:02:15

doesn't stand

00:02:17

together with all its planets

00:02:20

forming the solar system the sun

00:02:23

moves in outer space

00:02:25

relative to other stars the

00:02:28

solar system is a

00:02:32

system or complex of celestial

00:02:36

bodies connected by forces of attraction the solar system includes

00:02:40

the main star the sun 8 known

00:02:44

large planets with their satellites mercury

00:02:49

venus earth mars jupiter saturn uranus and

00:02:56

neptune

00:02:57

each planet has its own orbit in

00:03:01

which it moves around the sun,

00:03:04

the orbit is an imaginary line, a

00:03:08

full revolution around the sun is called a

00:03:11

code on earth, it lasts 365 days on

00:03:17

planets that are closer to

00:03:19

the sun, a year lasts less than those that are

00:03:23

further away, a full revolution

00:03:25

can take several Earth years,

00:03:28

also the planets revolve around their axis,

00:03:32

one such complete revolution is called

00:03:35

a day on earth, a day, that is, a revolution

00:03:40

around its axis is

00:03:42

equal to approximately 24 hours,

00:03:45

more precisely it is 23 hours 56 minutes 4

00:03:51

seconds,

00:03:54

how does the earth rotate around

00:03:57

its axis? Every day we observe how

00:04:02

the sun changes its location in

00:04:05

the sky in reality In fact, this earth

00:04:09

rotates around its axis,

00:04:12

during the rotation of the earth around its axis, the

00:04:16

sun illuminates

00:04:18

one side of the planet or the other, so

00:04:22

there is a change of day and night on the

00:04:25

illuminated side of the planet, where

00:04:28

on the opposite, unlit night, the

00:04:37

earth makes a full revolution around its axis in 24 hours. there is in one

00:04:41

day

00:04:42

the earth rotates from the west to the east,

00:04:46

that is, counterclockwise if you

00:04:49

look at the planet from the north

00:04:52

pole, so we

00:04:56

see the sunrise in the east and the sunset in the west of the

00:04:59

morning in the eastern countries begins

00:05:02

earlier than in the western countries, the

00:05:05

earth, like all the planets of the solar

00:05:08

system, moves in its orbit around the

00:05:12

sun, the

00:05:14

speed of movement is 30

00:05:17

kilometers per second, the earth moves in the

00:05:21

same direction as when rotating

00:05:23

around its axis, the

00:05:25

distance from the earth to the sun is

00:05:29

150 million kilometers,

00:05:33

one revolution around the sun the earth

00:05:36

makes 365 days and 6 hours in a year, which

00:05:41

turns out to be four years accumulates

00:05:45

one more day, so every fourth

00:05:49

year in February there are not 28 days but 29 days, due to the

00:05:55

tilt of the axis,

00:05:57

the earth moving around the sun substitutes

00:06:00

its northern or southern part for it, which is why the seasons

00:06:03

change

00:06:07

to study the movement of the 3 celestial bodies of the

00:06:12

earth, the sun and the moon

00:06:15

use the tool Telurians Luriy

00:06:19

helps to find answers to such questions

00:06:21

as day and night alternate, what is an

00:06:26

eclipse of the moon and the sun, why do

00:06:30

shadows appear, test your knowledge,

00:06:35

fill out the card, select only the

00:06:39

planets

00:06:41

Mars, Venus, earth, the sun is a star,

00:06:50

the sun gives our planet warmth and

00:06:55

sunlight,

00:06:57

the earth rotates around the sun in

00:07:02

one year, that is, 365 days in the solar

00:07:08

system, eight planets are Mercury,

00:07:13

Venus, earth, Mars, Jupiter, Saturn, Uranus and

00:07:21

Neptune, the earth rotates around its

00:07:25

axis in 24 hours, that is, in one day,

00:07:32

the line along which the planets move is

00:07:36

the orbit, listen to interesting facts about the

00:07:42

study of space The era of space exploration

00:07:46

began when a person looked

00:07:50

at the night sky and thought about what was

00:07:53

there. The idea of space travel

00:07:58

arose among people a very long time ago. The first

00:08:01

science fiction story describing

00:08:04

man's stay on the moon was written by

00:08:07

Johannes Kepler in 1609, the Russian scientist

00:08:13

Konstantin Tsialkovsky was one of the first

00:08:16

to propose the idea using rockets for

00:08:19

space flights he designed such a rocket

00:08:23

in 1903 do it

00:08:29

yourself page 117 118

00:08:34

read and answer questions

00:08:37

creative task make a model of the

00:08:40

solar system

00:08:43

evaluate your work using the ladder of

00:08:47

success on which step today will you

00:08:52

summarize today we repeated that the solar

00:08:57

system is a complex celestial bodies, we learned that when the

00:09:01

earth rotates around its axis,

00:09:04

day gives way to night, all eight planets

00:09:08

move along an imaginary line of

00:09:12

orbit, when the earth rotates around the sun, the

00:09:15

seasons change, we learned about

00:09:20

such an instrument as tilor, which is

00:09:24

designed to study the movement of 3

00:09:27

celestial bodies, the

00:09:29

sun, earth and moon

00:09:32

ours the lesson has come to an end, we

00:09:36

did a great job and learned a lot of new and

00:09:39

interesting things, see you again
