Experience launching a rocket for children. A summary of research on research "Flight of a rocket rocket. Lemon Inflaces Balloon

Summary: Chemical experience - invisible ink. Experiments with citric acid and soda. Experiments with surface tensiones on water. Mighty shell. Teach egg to swim. Animation. Experiments with optical illusions.

Does your baby love all the mysterious, mysterious and unusual? Then you definitely spend simple, but very curious experiences described in this article. Most of them will surprise them and even puzzle the child will give him the opportunity to make sure in practice in the unusual properties of ordinary items, phenomena, their interaction among themselves, to understand the reason for what is happening and in good by practical experience.

Your son or daughter will certainly deserve respect for peers, showing them experiments as tricks. For example, they will be able to "boil" cold water or with lemon to run a homemade rocket. Such entertainment can be included in the birthday of children of preschool and younger school age.

Invisible ink

To carry out experience, you will need: Half lemon, rolling, match, cup of water, paper sheet. 1. Issimate juice from lemon into a cup, add the same amount of water. 2. Suitting the match or toothpick with a wrapped wool in a solution of lemon juice and water and write something on paper with this match. 3. When the "ink" is dried, we heat the paper over the desktop lamp included. On paper, invisible words will appear.

Lemon Inflaces Balloon

To carry out experience, you will need: 1 tsp. Food soda, lemon juice, 3 tbsp. Vinegar, air ball, tape, glass and bottle, funnel. 1. Pour water into the bottle and dissolve a teaspoon of food soda in it. 2. In a separate dish, mix lemon juice and 3 tablespoons of vinegar and pour into a bottle through a funnel. 3. Quickly wear a ball on the neck of the bottle and firmly fix it with a tape. See what is happening! Food soda and lemon juice, mixed with vinegar, enter the chemical reaction, isolated carbon dioxide and create pressure that the ball is inflated.

Lemon starts a rocket into space

To carry out experience, you will need: a bottle (glass), a tube from a wine bottle, colored paper, glue, 3 tbsp. Limondo juice, 1 tsp. Food soda, a piece of toilet paper. 1. Cut from colored paper and glue paper strips from both sides of the wine plug so that the rocket layout is. We try on the "rocket" on the bottle so that the plug came into the neck of the bottle without effort. 2. Pour and mix water and lemon juice in the bottle. 3. Watch the food soda into a piece of toilet paper so that you can push the bottle into the neck and wind the threads. 4. Lower a bag with soda in a bottle and plug her cork-rocket, but not too tight. 5. We put a bottle on the plane and depart on a safe distance. Our rocket with loud cotton takes off up. Just do not put it under the chandelier!

Scattering toothpicks

To carry out experience, you will need: a bowl with water, 8 wooden toothpicks, a pipette, a piece of sugar-raffinad (not instant), dishwashing liquid. 1. We have toothpicks with rays in a bowl with water. 2. The bowl of the bowl gently omit a piece of sugar, - the toothpicks will start going to the center. 3. We remove sugar with a teaspoon and dripping a pipette into the center of the bowl of a few drops of liquid for washing dishes, - toothpicks "scatter"! What is happening? Sugar sucks water, creating its movement moving toothpicks to the center. Soap, spreading along the water, carries out particles of water, and they force the toothpicks to scatter. Explain to children that you showed them focus, and all the focuses are based on certain natural physical phenomena that they will study at school.

Mighty shell

To carry out experience, you will need: 4 halves of eggshell, scissors, narrow sticky tape, several complete cans. 1. Wrap sticky tape around the middle of each half of the egg shell. 2. Scissors cut the excess shell so that the edges are smooth. 3. Put four halves of the dome to the dome so that they make up the square. 4. Carefully put on top of the jar, then one more and more ... while the shell does not burst. Slues of how many cans have sustained fragile shells? Summarize the weight marked on the labels and learn how many cans can be put so that the focus is able. The secret of power is in the dome-shaped form of the shell.

Teach egg swim

To carry out experience, you will need: a raw egg, a glass with water, a few tablespoons of salt. 1. We put a raw egg into a glass with clean tap water - the egg will fall on the bottom of the glass. 2. take out an egg from a glass and soluble in water several spoons of salt. 3. Lower the egg into a glass with salty water - the egg will swim on the surface of the water. Salt increases water density. The more salt in the water, the more difficult to drown in it. In the famous dead sea, the water is so salty that a person can lie on her surface without any effort, without fearing to drown.

"Prix" for ice

To carry out experience, you will need: thread, ice cube, glass of water, pinching salt. Singing with a friend that with the help of a thread you pull the ice cube from a glass with water without sleeping hands. 1. Lower the ice into the water. 2. To put a thread on the edge of the glass so that it lay on the ice on the ice cube, floating on the surface of the water. 3. In bulk a little salt on the ice and wait for 5-10 minutes. 4. Take for the free end of the thread and the cutting ice cube from the glass. Salt, hitting the ice, slightly hits the small plot. For 5-10 minutes, salt dissolves in water, and clean water on the ice surface is fitted together with the thread.

Can it "boil" cold water?

To carry out experience, you will need: a dense handkerchief, a glass of water, a pharmacy gum. 1. Hope and discard the handkerchief. 2. Hall a full glass of cold water. 3. Cover the glass with a handkerchief and fix it on a glass of pharmaceutical rubber band. 4. I sell your finger the middle of the handkerchief so that it is 2-3 cm plunged into the water. 5. Mock the glass over the sink upside down. 6. Hold the glass with one hand, then you will hit it slightly on its bottom. Water in a glass begins to spill ("boils"). Wet scarf does not pass water. When we hit a glass, a vacuum is formed in it, and the air through the handkerchief begins to flow into the water absorbed by the vacuum. Here are these air bubbles and create the impression that water "boils".

Solominka Pipette

To carry out experience, you will need: Cocktail straw, 2 glasses. 1. Put near 2 glasses: one - with water, the other is empty. 2. Lower the straw in the water. 3. We get the straw from above the index finger and move to an empty glass. 4. Remove the finger from the straw - water flows into an empty glass. Having done the same few times, we will be able to transfer all the water from one glass to another. By the same principle there is a pipette, which is probably there is in your home first aid kit.

Solominka Flute.

To carry out experience, you will need: a wide straw for a cocktail and scissors. 1. Sleeping the end of the straw with a length of about 15 mm and cut it with the edges with scissors. 2. From the other end of the straw cutting 3 small holes at the same distance from each other. So it turned out the "flute". If it is low in a straw, slightly squeezing with her teeth, "flute" will begin to sound. If you finish with your fingers, then another hole "flutes", the sound will change. Now let's try to pick up some melody.

Solominka Rapira

To carry out experience, you will need: raw potatoes and 2 thin straws for a cocktail. 1. Put potatoes on the table. I get a straw in a fist and a sharp movement try to stick the straw in potatoes. Solominka will bend, but the potatoes will not drive. 2. Take the second straw. Close the hole above the thumb. 3. Sharply omit the straw. She will easily enter the potatoes and drive it. The air, which we closed with a thumb inside the straw makes it elastic and does not allow it to be worn, so it easily skeins potatoes.

Bird in a cage

To carry out experience, you will need: a piece of dense cardboard, a circulation, scissors, colored pencils or markers, thick threads, a needle and a ruler. 1. Cut from cardboard a circle of any diameter. 2. I must pierce on a circle in two holes. 3. Through the holes on each side, approximately 50 cm long by thread. 4. On the front side of the circle, we draw a cell for birds, and on a revolt - a small bird. 5. Rotating a cardboard circle, holding it in the ends of the threads. Threads will be twisted. Now dying their ends in different directions. Threads will spin and rotate the circle in the opposite direction. It seems that the bird is sitting in a cage. The effect of animation is created, the rotation of the circle becomes invisible, and the bird "turns out" in the cell.

How does the square turn into a circle?

To carry out experience, you will need: rectangular cardboard, pencil, felt-tumbler and ruler. 1. We put a line on the cardboard so that one end she touches her angle, and the other - the mid-opposite side. 2. We put the felt-tip pen on a cardboard 25-30 points at a distance of 0.5 mm from each other. 3. Let's switch to a sharp pencil of the middle of the cardboard (the middle will be the intersection of diagonal lines). 4. Prefer the pencil on the table vertically, holding it with hand. Cardboard should be freely rotated on the edge of the pencil. 5. We will spin the cardboard. A circle appears on the rotating card. This is just a visual effect. Each point on the cardboard when rotating is moving in a circle, as if creating a continuous line. The closest point is moving slower to the edge, her trace we perceive as a circle.

Strong newspaper

To carry out experience, you will need: a long line and a newspaper. 1. We put a ruler on the table so that it is half hung. 2. Moving the newspaper several times, put on the line, strongly knock on the hanging end of the line. The newspaper will fly away from the table. 3. And now we will unfold the newspaper and cover it the line, you will hit the ruler. The newspaper is only slightly raised, but will not fly anywhere. What is the focus? All items are tested air pressure. The larger the area of \u200b\u200bthe subject, the stronger it is the pressure. Now it is clear why the newspaper became so strong?

Mighty breathing

To carry out experience, you will need: deer hanger, strong threads, book. 1. Tear the book using threads to a relative hanger. 2. Hang a hanger on the lingerie. 3. Stand up near the book at a distance of approximately 30 cm. Helling on the book. She will slightly deviate from the initial position. 4. Now let's drink on the book again, but lightly. As soon as the book breaks out a little, let it fall. And so several times. It turns out that such repeating light blows can be shifted a book much further than one time heavily likes on it.

Recorted weight

To carry out experience, you will need: 2 tin cans from under coffee or canned food, paper sheet, empty glass bank. 1. We will deliver two tin cans at a distance of 30 cm from each other. 2. Put the sheet of paper from above to get a "bridge". 3. We put an empty glass jar on a sheet. Paper will not stand the weight of the bank and gets down. 4. Now add a sheet of paper accordion. 5. We put this "harmonic" into two tin cans and put a glass jar on it. The harmonica does not bend!

Before starting the thematic week, show the child a photo or presentation about the planets, the solar system, about space, read the thematic book.

• We make a rocket for space travel. The rocket can be made of chairs, pillows, boxes, cardboard, bottles, draw, loose from plasticine, lay out from counting sticks, cubes, designer.

Here are some examples of crafts "Rocket":

• Play the training of astronaut to flight.

Begins checking the player. Is it convenient on my head sits a helmet? (Turns, head slopes to the right, left, forward, back, circular rotation of the head).

Cosmonaut can move in space using a device placed in his back on his back. We check how tightly keeps the wrath. (Circular movements, raising and lowering shoulders).

Is numerous zippers and buckles well? (Turns and slopes of the case to the right, left, forward, back, circular motion of the body, slopes to foot footsteps).

Does gloves come close to hands tightly? (Rotational movements of hands with hands stretched forward at the chest level, variables and simultaneous machines with hands, raising hands up in front of them with alternate bending and extension of brushes, to lower the sides down, also alternately flexing and flexing handbrushes).

How does the radio work, not junk? (Semi-trained, jumps on two legs in place).

Boots do not hise? (Walking in a circle on socks, heels, external and internal footsteps, with sock, side gallop to the right, left, step by Guskom).

Is the "heating system" of the Skafandra? Is it easy to breathe in it? (Inhale - hands up, exhale - hands down).

• Run the rocket.

Put the paper rocket on the cocktail tube and hide into the tube so that the rocket soars:

Inflate the ball - the rocket, stick to it with a scotch tube for a cocktail. Thug through the room thread, grind it through the tube. Now let go of the ball. The air will start out of it, and the ball will fly.

• Having become acquainted with the planets of the solar system, you can depict them in different ways. - To make salted dough or plasticine, draw the cut-off potatoes or cork cover, lay out buttons or plasticine, make a mobile cardboard or fetal figures.

We made this figure: Drew a starry sky, splashing white paint on black paper with a brush. Each planet was separately, cut out and glued them to the starry sky.

The moon can be drawn so. Cut the circle from cardboard, draw the circles on it with wax crashes - crater, and then fill the entire moon with watercolor.

Flashlight "Constellation". Draw a constellation on black cardboard, make holes in places where stars are located. Stick the resulting cards on paper molds for cupcakes, put on a flashlight and tie the thread. And now burn the flashlight in a dark room and direct on the wall to get a projection of constellation.

Relevance:i often have a grandmother, she lives in Samara not far from the Museum and Exhibition Center "Samara Space", looking at the Soyuz Web Wearer Complex. I was interested in the question - why rockets take off? Why exactly on rockets fly into space? It became interesting, what the principle of the structure and launch of the rocket.
For this I decided to spend research work.

Purpose of the study: Find out the principle of the structure and launch of the rocket.

Research tasks:
1. To get acquainted with the history of missiles.
2. Find out which laws of physics are acting when rockets.
3. To get acquainted with the rocket device and its launch.
Object of research: reactive movement.

Subject of study: space rocket.

Hypothesis Research: What makes the rocket move in the airless space of space. What power pushes the rocket up? Perhaps this is specially designed by scientists fuel for missiles.

Research methods: Analysis of scientific literature on the topic, the search for material on the Internet, generalization, systematization. Work is problematic - abstract character.

The history of the occurrence of rocket
The Russian word "rocket" occurred from the German word "rockets". And this is a German word-diminishing from the Italian word "Rockka", which means "spindle". That is, "rocket" means "small spindle". It is connected with the form of a rocket: it looks like a spindle - a long, streamlined, with a sharp nose.
Rocket man invented a long time ago. The first rocket was created by a person at least 700 years ago. They were invented in China. The Chinese used them in order to make fireworks. They kept the rocket device in the secret for a long time, they liked to amaze stranss. Soon in many countries learned to make fireworks and festive salute to celebrate solemn days. For a long time, the rocket served only for the holidays, but then they began to use them for military purposes.
In the 13th century, the Chinese first applied rockets, as they were then called, "fiery arrows" against the Mongolian invaders and plunged the enemy into confusion and panic.
With Peter I, an unified signal missile "Sample 1717" was created, which remained in service until the end of the XIXVEK. She climbed to a height of one kilometer.
In the 20th century, the thoughts about flight into space for the first time appeared at the school teacher of Physics Konstantin Eduardovich Tsiolkovsky. He dreamed about how a man will fly into space. He called our planet with a cradle of mankind. Unfortunately, K.D. Tsiolkovsky died before the first ships went into space, but it is still called the Father of Cosmonautics. The founder, the creator of domestic cosmonautics is Sergey Pavlovich Korolev - an outstanding designer and a scientist. Under his leadership and on his initiative, the launches of the first artificial satellite of the Earth and the first cosmonaut Yuri Gagarin were carried out.

Structure of rocket
The rocket consists of three steps located one on the other. Each stage of the rocket consists of a motor and fuel tanks. The first turns on and the lowest level is running. This rocket is the most powerful, since its task is to lift the entire design into the air. When the fuel burns, and the tanks will be empty, the lower level is broken, and the engines of the second stage begin. At this time, the rocket is gaining speed and flies faster. When fuel ends, the second stage is broken down and turns on the work of the third, the last step, which is even more accelerating the ship. Here it turns on the first cosmic speed and the ship goes into orbit, and then one flies one, since the last stage of the rocket is almost completely combined when disconnected. The rocket has stabilizers - small wings at the bottom. They are needed in order for the rocket flying smoothly and straight, without stabilizers, it will hang out from side to side. Stabilizers change the whole picture. When the rocket begins to deviate in the side, or to drive aside, as it brings the car on a slippery road, the stabilizers are substituted under the flow of air with their wide part and these flow demolitions back.

Why does the rocket take off?
What power raises the rocket? This force is called reactive.
To understand what a reactive movement is a small experiment.
To do this, you will need: the air ball and the rocket model made of paper, clamp.
1. Influence the ball and close it with the help of the clamp.
2. Playing the ball inside the rocket.
3. Remove the clamp, let go of the ball.
4. Air exits, and the rocket moves in the air.
The rocket moves compressed air. His molecules, fly through the hole in the ball, and following the third law of Newton, that the action is equal to opposition, pushes the ball in the opposite direction. In the same principle, jet engines work.

For we will need experience : Cork from a wine bottle, bottle, water, citric acid, food soda, funnel, a piece of toilet paper, spoon, thread.

First make from traffic jam rocket, then pour water into a bottle (a little more than half, put a spoonful of soda on the toilet paper, wrap the soda in the paper so that it does not get enough sleep, and tie the thread, leaving one end long.

Then add citric acid through the funnel to the bottle and we take the water so that the acid is dissolved

I lower the bag with soda in a bottle, leaving the end of the thread outside and close the plug rocket

Now we remove the children for a safe distance and wait. When paper splashes, the soda will enter into a reaction with citric acid, carbon dioxide forms, which will push the cork from the bottle. This will take off our rocket, After making cotton while takeoff.
