Progress of educational activities:
The teacher and children enter the group (hall).
— Guys, do you like to travel?
- Yes!
— Tell me about your travels. Where have you already been at such a young age?
— My family and I were on vacation in Turkey... And we went to Sochi in the summer...
- Today you and I will also go on a trip. And it will be a virtual trip into space! The word travel is familiar to you. What does the word “virtual” mean?
- Fictional.
- That's right, “virtual”, that is, not real, imaginary. I hope you like to fantasize?
- Yes!
- Then let's not waste time!
— To go on a space journey we need to become... What do they call people who fly into space and conduct tests there?
- Cosmonauts.
-Exactly! Let's imagine ourselves as astronauts?
- Yes.
— Cosmonauts have special suits. What are they called?
— Spacesuits.
— Unfortunately, you and I don’t have spacesuits. But, there are such interesting aprons and our imagination. Put them on and imagine that they are spacesuits.
- In front of me are real astronauts! In such spacesuits you and open space not scary!
- It's time to go! What will we fly on? - On a rocket?
— We have soft modules. Let's try to turn them into a rocket?
- Yes.
— I propose to arrange them in the shape of a circle (these will be our seats) and don’t forget to leave room for the landing hatch. Arrange modules. We take our seats in the rocket.
- Attention! There are 10 seconds left before the rocket launch. - Guys, distribute the air in such a way as to count from 10 to 1 and loudly and clearly pronounce the word “launch.” We take in air through the nose... We begin counting down the time: 10,9,8,7,6,5,4,3,2,1. Start! An audio recording of the sound of a rocket taking off is played.Cosmic music sounds. The teacher turns on the disc lamp.
- Guys, what's going on? The teacher gets up and begins to imitate the state of weightlessness.
- This is weightlessness.
- We're in space. There is no gravity here. Therefore we are in a state of weightlessness. How beautiful it is here!
A picture of planet Earth appears on the screen.
- Guys, look out the window. What do you see?
- This is our Earth.
- That's right, this is our home planet - Earth. This is what it looks like from space. What shape does it have?
- The shape of a ball.
— The earth is a huge ball. Just look how beautiful she is! It is often called the "blue planet." Why do you think?
— Because there is a lot of water on Earth.
- Well done! There are 9 planets in the solar system, among which the most unique planet- This is planet Earth. Because only on it does life exist. But it was not always so. Do you want to know how our planet came to be?
- Yes.
— Some scientists suggest that the Sun was originally a huge hot ball. One day there was an explosion on it, as a result of which huge pieces broke off from the Sun, which became known as planets. At first our planet was hot, but gradually it began to cool. Look, I have a thermos with hot water. I suggest you fantasize and imagine that this is our hot planet. Now I will open the lid and “our planet” will begin to cool down. What happens?
— Steam is formed.
— We see how the water begins to evaporate. In cold air, the steam turns back into water and begins to accumulate. We can see this if we hold the glass over the thermos. What happens when too many water droplets accumulate on the glass?
- They will fall back into the thermos.
- You're right. This is exactly how, according to scientists, water fell in the form of rain onto the already cooled Earth, and the first ocean was formed. And life arose in the ocean. Unfortunately, it is impossible to know exactly what the Earth was like many billions of years ago, so these are just scientists’ guesses.
An image of the Moon appears on the screen.
- Guys, just look, we are flying past some celestial body. What is this?
- This is a planet.
— Maybe my riddle will help you recognize this planet:
Sometimes he loses weight, sometimes he gets fatter,
It shines from the sky, but does not warm,
And to Earth only one
Always looking away.
- This is the Moon.
— The moon is a satellite of the earth. What do you think a satellite is?
— It revolves around the earth.
- That's right, guys, a satellite is heavenly body which orbits the planet. The moon is the celestial body closest to the earth and the only one where humans have been. There is no water, no air, no weather on the moon. And its surface is strewn with craters - pits that appeared from the impacts of huge meteorite stones billions of years ago. Want to see how it was?
- Yes!
“Then, I suggest you go to the next compartment.” The teacher and children approach the table on which there is a bowl of flour.
- Guys, look, there is a bowl of flour in front of you. Let's imagine that this is the surface of the Moon, covered cosmic dust. And these balls are jumpers - meteorites. Shall we stage a meteorite attack on the lunar surface? I propose throwing “meteorites” from different heights, then to see if the same craters are formed. Children and the teacher throw bouncing balls into a bowl of flour from different heights.
— What happens to the flour?
- Pits form in it.
-Are they the same?
- No!
— What determines the size of the pit-craters?
- Depending on the size of the jumping ball.
- And the depth of the hole?
- From the height from which he was thrown.
- That's right guys, the higher the jumping ball is from the surface during the throw, the higher the speed of its flight, which means the hole-crater will be deeper. And the size of the meteorite affects the size of the crater formed. Look at the screen. This is a photograph of the surface of the moon from space. Is our imaginary lunar surface similar to the real one?
- Yes.
“I suggest we return to our landing compartment and see what we are flying through at the moment.”
An image of Mars appears on the screen.
- This is the most mysterious planet in our solar system - Mars. It is also called the “red planet”. Why do you think?
- Because it is red.
- You are right, precisely because it has a reddish-brown surface tint. And it is mysterious because people have long believed that there is life on Mars. What are the creatures that live on Mars called?
- Martians.
- They seem to be glad to meet us and send their musical greetings! Shall we dance with them? The teacher turns on the musical physical exercise “Aliens”.
- Guys, in fact, man never discovered any Martians on Mars, although... maybe he just didn’t look well. But the rovers sent to the planet ( spacecraft, designed for movement on the surface of the planet Mars) were able to discover there the highest mountain in the solar system, the deepest valley and the most extensive dust storms in the solar system, which cover the entire planet and can last for several months.
An alarm sounds on the spaceship.
— Guys, instruments show that now there is a period of dust storms on Mars. We flew too close and our spaceship received damage. Therefore, it is urgent to return to Earth. Fasten seat belts. We are returning to Earth. An audio recording of the rocket landing and landing is played.
- Here we are at home, on native Earth... It’s only a pity that we were not able to see the rest of the planets of the solar system. Although, at the cosmodrome there is a laboratory in which you and I can create our own space. Let's imagine ourselves as research scientists?
- Yes!
— Guys, all the objects at the cosmodrome are guarded, so in order to get into the laboratory we need to be told the safety rules when conducting experiments. They are encrypted on these clue cards. Let's try to decipher them. The teacher takes turns showing the children hint cards with the rules for conducting experiments. Children name the rules.
- You can ask questions, listen, look, smell and touch only if an adult allows it. You can’t taste it, talk or shout loudly, you need to be careful not to break anything.
- Well done boys! Now we can go to the laboratory. The teacher and children approach the table, on which there are cups with a special solution, cups with sunflower oil, pipettes and skewers for each child.
— There is liquid in the glasses on the table with a very pungent odor. It must be sniffed with caution. And under no circumstances should you taste it. This will be our space environment. In it we will create a system of planets. To do this, we need to take a little oil from a cup into a pipette. The teacher and children draw oil into a pipette. If children do not know how to use a pipette, then the teacher explains to them in detail how to do it: take the pipette in your right hand, like a pen or pencil, just hold it by the rubber part. Squeeze the rubber part of the pipette with your index finger and thumb, then lower the pipette into the oil, then quickly release your fingers and lift the pipette above the cup. There was oil in the pipette.
- Now carefully drop a large drop of oil into a glass or several small drops in the same place ( alternately squeezing and unclenching the rubber part of the pipette with the index and thumb of the right hand). Watch the drop. In the water it would float up and spread over the surface like a round speck of fat. And in a special solution, the drop floats in a beautiful golden ball. This is our first planet. You can even come up with a name for it. For example, call it by your name. And now, using a skewer or pipette, you can add new planets, combine them into one huge one, or, conversely, divide them into several. In your own cosmos, you are powerful creators! Children experiment on their own and observe what is happening.
- Guys, the laboratory is closing, and it’s time for us to return to kindergarten. We will walk along the path of stars and go straight to kindergarten. The teacher and children walk along a path made of stars.
— Did you like our virtual trip?
- Yes!
— What was the most interesting thing on our trip?
— I liked to participate in the formation of craters on the Moon. I liked dancing with the Martians. And what I liked most was creating my own planets...
(If children find it difficult to answer, you can ask leading questions. What planets did our spaceship fly past? Why is the Moon called a satellite of planet Earth? What are craters? Who did we meet on Mars? Why did we have to interrupt the trip? What did we do in the laboratory at the cosmodrome?)
— I liked traveling with such wonderful guys like you!
— Guys, during the lesson we managed to learn a lot of new and interesting things about space and space objects, and I would really like you to continue studying this topic. It's so interesting! And the educational cards “Cosmos” will help you with this. Goodbye, guys! Don't forget to tell your friends about our wonderful trip!

Experiments on the theme "Space"

Experiment No. 1 “Making a cloud.”

Target:

- introduce children to the process of formation of clouds and rain.

Equipment: three-liter jar, hot water, ice cubes.

Pour into a three-liter jar hot water(approximately 2.5 cm). Place a few ice cubes on a baking sheet and place it on top of the jar. The air inside the jar will begin to cool as it rises. The water vapor it contains will condense, forming clouds.

This experiment simulates the process of cloud formation as warm air cools. Where does rain come from? It turns out that the drops, having heated up on the ground, rise upward. There they get cold, and they huddle together, forming clouds. When they meet together, they increase in size, become heavy and fall to the ground as rain.

Experiment No. 2 “Solar System”.

Target:

Explain to the children. Why do all planets revolve around the Sun?

Equipment: yellow wooden stick, threads, 9 balls.

Imagine that the yellow stick is the Sun, and 9 balls on strings are the planets

We rotate the stick, all the planets fly in a circle, if you stop it, then the planets will stop. What helps the Sun hold up the entire solar system?..

The sun is helped by perpetual motion.

That's right, if the Sun doesn't move, the whole system will fall apart and this eternal motion won't function.

Experiment No. 3 “Sun and Earth”.

Target:

Explain to children the relationship between the sizes of the Sun and Earth

Equipment: big ball and bead.

The size of our beloved star is small compared to other stars, but by earthly standards it is huge. The diameter of the Sun exceeds 1 million kilometers. Agree, even for us adults it is difficult to imagine and comprehend such dimensions. “Imagine, if our solar system was reduced so that the Sun became the size of this ball, then the earth, along with all the cities and countries, mountains, rivers and oceans, would become the size of this bead.

Experiment No. 4 “Day and Night”.

Target:

- Explain to children why there is day and night.

Equipment: flashlight, globe.

It's best to do this on a model. solar system! . You only need two things for it - a globe and a regular flashlight. Turn on a flashlight in a darkened group room and point it at the globe approximately your city. Explain to the children: “Look; The flashlight is the Sun, it shines on the Earth. Where it is light, it is already day. Now, let’s turn it a little more - now it’s shining on our city. Where the rays of the Sun do not reach, we have night. Ask the children what they think happens where the line between light and dark is blurred. I’m sure any kid will guess that it’s morning or evening

Experiment No. 7 “Who invented summer?”

Target:

- Explain to children why there is winter and summer.

Equipment: flashlight, globe.

Let's look at our model again. Now we will move the globe around the “sun” and observe what happens to the lighting. Due to the fact that the sun illuminates the surface of the Earth differently, the seasons change. If it is summer in the Northern Hemisphere, then in the Southern Hemisphere, on the contrary, it is winter. Tell us what the Earth needs whole year in order to fly around the Sun. Show the children the place on the globe where you live. You can even stick a little paper man or a photo of a baby there. Move the globe and try with your children to determine what time of year it will be at this point. And don’t forget to draw the attention of young astronomers to the fact that every half revolution of the Earth around the Sun, polar day and night change places.

Experiment No. 5 “Eclipse of the Sun.”

Target:

- Explain to children why there is an eclipse of the sun.

Equipment: flashlight, globe.

Many phenomena occurring around us can be explained even completely small child simple and clear. And this must be done! Solar eclipses in our latitudes - a great rarity, but this does not mean that we should ignore such a phenomenon!

The most interesting thing is that the Sun is not made black, as some people think. Observing the eclipse through smoked glass, we are looking at the same Moon, which is located opposite the Sun. Yes... it sounds unclear. Simple means at hand will help us out.

Take a large ball (this, naturally, will be the Moon). And this time our flashlight will become the Sun. The whole experience is to hold the ball against the light source - here you go black Sun... How simple it all turns out.

Experiment No. 6 “Far - close.”

Target:

Determine how distance from the Sun affects air temperature.

Equipment: two thermometers, a table lamp, a long ruler (meter).

PROCESS:

Take a ruler and place one thermometer at the 10 cm mark and the second thermometer at the 100 cm mark.

Place a table lamp at the zero mark of the ruler.

Turn on the lamp. After 10 minutes, record the readings of both thermometers.

RESULTS: The closest thermometer shows a higher temperature.

WHY? The thermometer that is closer to the lamp receives more energy and therefore heats up more. The further the light spreads from the lamp, the more its rays diverge, and they can no longer heat up the distant thermometer much. The same thing happens with planets. Mercury, the planet closest to the Sun, receives the most energy. Planets farther from the Sun receive less energy and their atmospheres are cooler. Mercury is much hotter than Pluto, which is very far from the Sun. As for the temperature of the Planet’s atmosphere, it is also influenced by other factors, such as its density and composition.

Experiment No. 7 “Space in a jar.”

Work method:

1) take the prepared container and put cotton wool inside

2) pour glitter into the jar

3) pour a bottle of glycerin into the jar

4) dilute food coloring and pour everything into a jar

5) top up 6) if you made it in a jar, then close everything with a lid and seal it with glue or water plasticine

Interesting experiments for children at home will allow you to lure your child into an interesting activity, as well as stimulate his cognition and desire to learn new things. Various experiments can be carried out from the moment when the child is able to perceive information or at least carefully observe the process. The best option For the simplest experiments, you can call the age of 2 years, after which, following the growth of the child, you can complicate the experiments and attract your child to help.

Modern science for children and parents allows you to use available materials to conduct various experiments at home. Children in the world of science will be able to better learn all the features of what is happening around them, as well as learn a lot of useful and interesting things for themselves. Science through the eyes of children will take on a completely different look, and simple and funny manipulations carried out during all procedures will certainly interest your child, and he will be happy to take part.

Simple science: experiences and experiments for children

Experiments for children aged 5-7 years will be the optimal solution for a great time with your baby. School years are beginning and instilling in children with the help of various interesting “tricks” will be a good solution. Fun Science conducted at home, opens up a completely different world for the child, in which seemingly simple things turn into something unimaginable.

Simple scientific activities for children of different ages will allow your child to better understand the characteristics of different substances, their combinations and will arouse a healthy interest in learning new things, but for now we bring to your attention 6 experiments that can be carried out at home.

Chemical experiments for children are an important point, because you can not only discover something new for your child, but also explain the peculiarities of behavior with different substances and the precautions that should be observed. We present to your attention 3 chemical experiments that can be carried out at home.

Non-Newtonian fluid

A fairly simple experiment that requires only water and starch. You can use any color of food coloring to add color. It is necessary to mix water with starch in a ratio of 1 to 1. The result is a substance that, in its calm form, retains all the characteristics of water, but when struck or attempted to break, it acquires characteristics more characteristic of a solid body.

Turning milk into a cow

An interesting experiment using milk and vinegar. Milk should be slightly warmed in the microwave or on the stove, without bringing to a boil. After this, add vinegar to the container with milk and begin to actively mix. After some time, clots begin to form, consisting of casein, a protein found in cow's milk. If there is a large accumulation of these clots, you should strain the liquid, and collect the collected casein clots into one, from which you can sculpt a figurine of a cow or any other object. After drying the product, after a few days you get a durable toy made of natural material with hypoallergenic characteristics.

"Elephant Toothpaste"

An impressive experiment that evokes a sea of positive emotions and delight in the child. To carry it out you will need hydrogen peroxide (6%), dry yeast, liquid soap, food coloring and some water. To get the effect, you need to add yeast to a mixture of water, soap and peroxide. The exothermic reaction caused by this will lead to an instant expansion of the resulting mixture, which will immediately flow out of the container like a fountain. To keep your home clean, it is better to conduct this experiment outside, because the height of the jet can reach several meters.

However, chemicals are not the only thing you can use to please your children. There are also experiments for children in such fields of science as physics. We have prepared 3 of the simplest ones especially for you.

Leaky package

To carry out the experiment, all you need is a regular bag, a little water and a few sharp pencils. You need to fill the bag with water and tie it tightly. After this, the moment of true surprise for your children comes when, having completely pierced the bag with a pencil, water will not flow from it. This is due to the fact that polyethylene is a fairly elastic material and can envelop a pencil, preventing water from leaking out.

Frozen soap bubble

To implement this idea, you will need a regular soap bubble and suitable weather conditions (preferably -15 degrees). The child will be able to observe how quickly an ordinary bubble replaces its state of aggregation, freezing and taking on a completely different appearance.

color tower

All you need is water, sugar and various food colorings. By mixing water and sugar in different proportions, you get mixtures of different densities, which allows them not to mix with each other in one vessel, thus creating a tower of different colors.

You can also learn a lot of interesting things by watching the program simple science, exciting experiences for children, videos of which we have already prepared for you.

Space for children preschool age, which interesting topic! And the most important thing is that we parents don’t even need to get our children interested in it. They themselves are interested in the Moon, the planets of the solar system, what is there in the sky, how far the stars are from us and whether they have names. Preschoolers have a very inquisitive mind and our task is to give them answers in game form. My son and I have already put together a whole series of activities and games about space. If you are going to give your preschooler answers to questions, I am sure that in one of my articles you will find information about this that will give an answer at your child’s developmental level. At the end of the article you will see a list for the entire series of classes.

From the article space for preschool children you will learn

Poems about space for little ones
Studying nebulae in space with a child
Video for children about space

Speaking of outer space. I was recently looking through a folder creative works, where I collect Alexander’s works and sign the date of their execution. So, there I found one wonderful picture that amazed me and my husband to the core. Alexander likes shiny materials for drawing, we used them a lot for the New Year holidays. And so 5 months ago (you understand the height of spring) Alexander begged me for all the tubes of glitter. To avoid gigantic losses, I put the paints in the palette, water, and brushes on the table and went to the kitchen. This is what my preschooler drew.

Starry sky drawing3 years 6 months

Weightlessness: how to feel it

Weightlessness is a thing that is not easy to feel on Earth. It is felt at a certain depth under water - this is how astronauts train, in modern high-speed elevators you can also feel it, and for children the most easy way this is a swing. But not just when riding on a swing, but at an almost 90-degree tilt, when the child’s soft seat seems to come off the seat. It is in these split seconds that weightlessness is felt.

While studying weightlessness as part of the space project for preschool children, we watched a couple of videos. They are designed for older children - schoolchildren, but we were still interested.

Lesson from Space: The Physics of Zero Gravity

Amateur Experiments: Weightlessness on Earth

After watching the second video, Alexander realized that cosmonauts spend a year training to fly into space. One of the main trainings is the vestibular apparatus. Which, as you and I know, ends its development at 7-10 years old, and now my preschooler is only 3 years 11 months old. During my last visits to the park, I noticed that my young cosmonaut is trying to run where he used to walk, wants to “fly” higher on a swing, and even found in our park such a setup for riding on boards, where he tries to run to the very top . But so far he has not succeeded.

You can find out what exercises we did at home to train the vestibular apparatus.

Experience for preschool children with rocket launch

I wanted to complete our flight to the Moon, which we talked about in the post, by launching the Lunokhod. But not the lunar rover, nor any other of Alexander’s 276 cars wanted to move with the help of a balloon. It’s good that I try everything myself before showing it to the child, otherwise we would both be disappointed. Nothing, then we’ll launch a ball in the shape of a rocket! And even if all the mothers on the planet had already performed this trick with their children, I still wanted to repeat it, because the child’s emotions are worth it.

After trying it in a child's room, I realized that it was not long enough for a delightful launch. Therefore, our experience was transferred to the hall, where I tied one end of a woolen thread (you can use any) to the door to the terrace, and the other to a children's highchair. Flight length is approximately 5 meters. In advance, I put a plastic tube and tape on the thread so that the ball would be attached to the tube.

It was I who attracted my husband to help, he is holding a rocket from a ball.

This surprise awaited Alexander upon his return from the lyceum. The child ran to take off his shoes and wash his hands to see what his mother had come up with this time. Needless to say, we repeated the rocket launch experiment many times?
10,9,8,7,6,5,4,3,...START!

But the most important thing is probably not the child’s new impressions, but his new skill that he acquired after that. How long it took Alexander and I to learn to blow! , on boats, at and many other things we did on this topic. And finally, almost at the age of 4, it happened - the child just wanted to cheat balloon. He wanted to launch HIS rocket and he did it! I don’t know how many times that day he inflated the balloons, in the evening dad begged for mercy and asked to remove these balloons out of sight, but that was not the case...

IN Lately Alexander really likes to write everything down and it’s probably difficult to fully understand what I mean by this, so I’ll give a clear example. We often study using materials I have printed out - drawing along the lines to practice our hands. So this time, in the printed materials about space, there were tasks to circle the colors of the stars highlighted with dotted lines. The child traced them, took markers and began to write the words he had just circled on English language on a magnetic board.

The first word was written by him in capital letters and I simply drew his attention to the fact that in the assignments he wrote them in a written font. Which resulted in words being written in two fonts on the board. The whole process took Alexander 30-40 minutes, and therefore one of the planned classes was postponed to the next day. But in such situations, I adhere to the point of view “let the child do what interests him.”

And yes, my preschooler writes either with his left or right hand. He clearly hasn’t made up his mind yet, and maybe he won’t make up his mind. Time will tell; this process cannot be forced.

Somehow I got distracted from the topic of space.

Poems not only develop memory and literary taste, they can also be very educational. If you have just started the topic, it will be useful to learn this wonderful poem by Hite. It presents the planets of the solar system in order in a very easy, memorable way. Its study can be timed to coincide with Cosmonautics Day or simply as an interesting activity. Once your child knows the order of the planets, you can make layouts and create.

And here is another poem about the Milky Way, written by Rimma Aldonina. In order for a preschooler to clearly understand what is being said in the poem, look at the children's encyclopedia with him on the spread about Milky Way. And the logical continuation after studying would be most interesting creativity– drawing nebulae, which we will talk about below.

Experience on the theme of space - creating nebulae

There are many beautiful, colorful nebulae in our Galaxy. As part of the space project for preschool children, we conducted an experiment that will clearly, vividly and interestingly show what nebulae look like. It has only one drawback: it is very difficult to stop! I just want to try different colors, their combination, change the fat content of the milk. I will advise you dear parents, continue until your preschooler has exhausted his questions.

Reference: A nebula is a section of the interstellar medium that stands out due to its radiation or absorption of radiation against the general background of the sky.

We decided to study nebulae in more detail (for our 3-year-old level, of course). First we read about them in existing books.

Let's start creating our nebula.

For this we needed:

milk with good fat content (I took 6%)
pipette
food colorings
cotton buds
dishwashing liquid

I conducted my first experiment with the nebula myself. The result exceeded even my expectations - the nebula looked straight out of space! I focused the child’s attention on the fact that if we simply stir everything with a stick, then very quickly our milk will turn into a dirty liquid. You need to draw on milk carefully, calmly moving the colors across the surface. Alexander, of course, couldn’t wait to make such beauty himself, and when my “masterpiece” was finished, I poured pure milk for the child.

First, he dropped a few drops of different dyes from a pipette. It is advisable to drip it at a distance from each other so that the colors do not mix. The child then takes a cotton swab, dips it in the detergent, and places it in the center of the colored drop.

We observe the reaction and carefully, superficially draw on the milk. We repeated these drawings four times, the first was mine, in total it took me two cartons of milk. I'll show you how the child did it and his nebulae.

We really enjoyed this space-themed experience. If you are wondering why the dye does not immediately mix with milk and the colors of the dye do not mix with each other, here is a little help:

In addition to water, milk contains vitamins, minerals, proteins and tiny particles of fat, as if suspended in solution. Proteins and fat are very sensitive to changes in solution, in in this case milk. The secret of this trick is precisely in a drop of detergent or liquid soap, which weakens chemical bonds, holding fats and proteins in solution and reducing surface tension in milk. There's a storm going on chemical reaction, which we can observe thanks to food coloring. Once the detergent is evenly mixed with the milk (partly dissolved, partly attached to the fat molecules), the reaction subsides and stops. That's the secret of this entertaining chemical experience. To replicate the color explosion in milk, simply add another drop of detergent.

Space – video for preschool children

As you know, children perceive information differently. Some people need to touch it to understand. Some people need to see it, but others need to work on the theme in a game, in poetry, in creativity. The final step in space exploration for preschool children may be watching a video. I will share with you only those that my boy was delighted with.

Video about space Encyclopedia for preschoolers

Astronomy for the little ones

Apparently the author of the title assumed that children begin to be interested in this science in primary school, he just doesn't know my son. But we are talking about preschoolers, and so that you don’t sit a two-year-old child in front of the screen, I’ll tell you that the video is suitable for ages 4-5.

Peppa fans will be able to carefully study the location of the planets in the solar system. In this case, the video starts from the farthest planet from the Sun to the closest.

And finally, I’ll mention a video of my childhood, which is suitable for older preschoolers and younger schoolchildren. A fantastic story about the girl Alice, her geologist father and the bird Talker. Remember?

The mystery of the third planet

So, dear friends, as you can see, space is very exciting for preschool children and you shouldn’t wait until they start studying astronomy at school. Browse our other space activities and I'm sure you'll find some interesting games for your preschoolers, as well as lots of experiences and experiments.

Experiments on the theme "Space"

Experiment No. 1 “Making a cloud.”

Target:

- introduce children to the process of formation of clouds and rain.

Equipment:three-liter jar, hot water, ice cubes.

Pour hot water into a three-liter jar (about 2.5 cm). Place a few ice cubes on a baking sheet and place it on top of the jar. The air inside the jar will begin to cool as it rises. The water vapor it contains will condense, forming clouds.

Experiment No. 2 “Solar System”.

Target:

Explain to the children. Why do all planets revolve around the Sun?

Equipment:yellow wooden stick, threads, 9 balls.

Imagine that the yellow stick is the Sun, and 9 balls on strings are the planets

We rotate the stick, all the planets fly in a circle, if you stop it, then the planets will stop. What helps the Sun hold up the entire solar system?..

The sun is helped by perpetual motion.

That's right, if the Sun doesn't move, the whole system will fall apart and this eternal motion won't function.

Experiment No. 3 “Sun and Earth”.

Target:

Explain to children the relationship between the sizes of the Sun and Earth

Equipment:big ball and bead.

Experiment No. 4 “Day and Night”.

Target:

- Explain to children why there is day and night.

Equipment:flashlight, globe.

The best way to do this is on a model of the solar system! . You only need two things for it - a globe and a regular flashlight. Turn on a flashlight in a darkened group room and point it at the globe approximately your city. Explain to the children: “Look; The flashlight is the Sun, it shines on the Earth. Where it is light, it is already day. Now, let’s turn it a little more - now it’s shining on our city. Where the rays of the Sun do not reach, it is night. Ask the children what they think happens where the line between light and dark is blurred. I’m sure any kid will guess that it’s morning or evening

Experiment No. 7 “Who invented summer?”

Target:

- Explain to children why there is winter and summer. Equipment: flashlight, globe.

Let's look at our model again. Now we will move the globe around the “sun” and observe what happens to

Lighting. Due to the fact that the sun illuminates the surface of the Earth differently, the seasons change. If it is summer in the Northern Hemisphere, then in the Southern Hemisphere, on the contrary, it is winter. Tell us that it takes the Earth a whole year to fly around the Sun. Show the children the place on the globe where you live. You can even stick a little paper man or a photo of a baby there. Move the globe and try it with your children

determine what time of year it will be at this point. And don’t forget to draw the attention of young astronomers to the fact that every half revolution of the Earth around the Sun, polar day and night change places.

Experiment No. 5 “Eclipse of the Sun.”

Target:

- Explain to children why there is an eclipse of the sun. Equipment: flashlight, globe.

Many of the phenomena happening around us can be explained simply and clearly even to a very small child. And this must be done! Solar eclipses in our latitudes are very rare, but this does not mean that we should ignore such a phenomenon!

Take a large ball (this, naturally, will be the Moon). And this time our flashlight will become the Sun. The whole experience consists of holding the ball opposite a light source - here you have the black Sun... How simple it all turns out.

Experiment No. 6 “Far - close.”

Target:

Determine how distance from the Sun affects air temperature.

Equipment: two thermometers, a table lamp, a long ruler (meter).

PROCESS:

Take a ruler and place one thermometer at the 10 cm mark and the second thermometer at the 100 cm mark.

Place a table lamp at the zero mark of the ruler.

Turn on the lamp. After 10 minutes, record the readings of both thermometers.

RESULTS: The closest thermometer shows a higher temperature.

Experiment No. 7 “Space in a jar.”

Work method:

1) take the prepared container and put cotton wool inside

2) pour glitter into the jar

3) pour a bottle of glycerin into the jar

4) dilute food coloring and pour everything into a jar

5) top up 6) if you made it in a jar, then close everything with a lid and seal it with glue or water plasticine
