Scenario for the chemical evening “Do-it-yourself miracles.”
introduction teachers. Dear Guys! Today, seventh, eighth, and ninth grade students have gathered here. Each of you has your own task. Eighth-graders prepared interesting experiments, showed various “miracles* and revealed the secret of each miracle.” Ninth graders, you are not just spectators, be on the alert, carefully follow everything that is happening, be prepared to answer the questions that the eighth graders will ask you. Your role, seventh graders, is to decide for yourself one question: is the science of chemistry interesting, do you want to study it? Of course, in chemistry, as in any science, in addition to the entertaining, there will also be difficult things. But it’s difficult, but interesting - that’s what thinking person It is precisely necessary that our mind should not be in idleness and laziness, but should constantly work, work and work. At the very end of our meeting, I will ask you one single question, and you will answer it, Now let's get started To miracles."
Four students come out.
1st student. It's hot here, I'm thirsty. Who 6 ask for water?
2nd student. I would drink a lot haZiva without syrup.
3rd student . Oh, I like it with syrupjust a little bit, a little bit.
4th student. Brothers, I need a cow -I want fresh milk!
The 5th student comes out. In his hands he has a large flask with liquid.
5th student. Are you guys thirsty? In countno fabulous liquid, I can handle miracles, II'm teaching chemistry. Put up the glasses! ExperienceWe will definitely carry it out, everything is according to plan.
The guys take glasses from the table and place them in them, in which solutions of the necessary substances are placed on the bottom. The 5th student pours from the flask to everyone WHAT He Asked.
5th student. Here's water, here's soda, here'sfresh milk, it turned out very cleverly, and the secret easy to find out.
The guys pretend that they want to drink the contents of the glasses.
5th student . Stop guys, wait a minutethere was no trouble, please don't drink anythingno water, no water. There are serious prohibitions in this strict office. Remember everything, friends: hereYou can't drink or eat.
1, 2, 3 We are familiar with miracles, we can do them ourselves.
5th student . The first miracle happenedwas it in the glasses?
1st student. And the answer is quite simple - it wasMy glass is empty.
2nd student . I have soda in my glass.
3rd student . Along with it is methyl orange.
4th student. Mine contains barium chloride.
5th student. What does this mean? Guess,ninth grade. We count on you! Not composedIt's hard for you to understand what's in the flask...
All ninth graders: Acid!
5th student . You probably know her rank?
9th Class. Sulfuric!
They leave. The 6th student comes out.
6th student. I'm already in the wonders of chemicalsI'll make a fire without fire, without matches. OnI add a bed of splinters and firewood and the fire is ready. I'll take itput some cotton wool in your hand, soak it in alcohol, put it on the firedrop: burn, if I want!
He does everything he says, and the fire lights up.
6th student. I'll tell you my secret, NikaThere's no secret here. Hid here under the fireincendiary mixture. We are familiar with miraclesWe can make them ourselves!
Leaves. 1st student appears
7th student. I have a calm experience, withoutfire and flame. I will ask questions. Nineclass, attention!
Conducts an experiment with phenolphthalein.
7th student. I'm not afraid of acids, evenvery strong. But in alkali solutionsI like raspberry. Brighter than the juice of all raspberries, who am I?
9th Class. Phenolphthalein!
The next experiment is with methyl orange.
7th student. In alkalis I am very yellow,and in acids it is very red. And the environment is neutralnoah - the color orange, beautiful. Indicatorvery important, what is my name?
9th Class. Methyl orange.
Experience with a piece of universal indicator paper.
7 - and student. This yellow piece of paper will indicate everythingwithout difficulty: it will turn blue - there is alkali in the flask, paintNo - acid. If the environment is neutral - notwill change color then. We are for these instructions as shall we call her?
9th Class. Universal!
Leaves. The 8th student comes out.
8th student. We are familiar with miracles - dowe can do them ourselves. Ninth grade, attention, there will beyou have a task. Pours onto a regular boardwater, and a glass of melted snow is also placed there.
The 1st student comes out.
1st student. I pour salt into a glass, and you,my friend, please interfere. I count to fiveA You twist everything with a stick.
He slowly counts so that the glass has time to freeze.
8th student. The chemical glass froze, process...
9th Class. Endothermic
The 8th and 1st students leave. The 9th student comes out.
9th student. All water, snow and solution,boring conversation... I have other plans:I'll light a flame on the grid.Sets fire to a pile of sand soaked in alcohol.
I don’t know how to do that yet, snakes will crawl out of the sand. Scary, biting, won't you cry from fear? Aren't you afraid? Well, look. Not all at once. Wait. To see the snakes, you need to warm them up well, but while I wake them up, I’ll tell you something else.
He speaks and at the same time demonstrates experience,
One summer I had a sore throat for a very long time. They prescribed me to rinse with furacillin for a sore throat. Still, the sore throat went away, even though I fought it for a long time. And there are two bottles of that furacillin left. Today we whitewashed the walls and washed our hands of lime. I decided to pour the old medicine into this water. I was terribly surprised, I even shuddered when the lime water turned reddish-red. I brought the rest to school, and now furacillin determines the alkali for us, just like phenolphthalein. Does not change color in water, does not change in acid, in alkalis furacillin is bright, like an orange.
He turns again to the experience with “black snakes”.
Alcohol burns and produces a lot of heat. It decomposes soda with heat into carbon dioxide. It chars the sugar - that's where the blackness comes from. This carbon dioxide inflates the sugar with bubbles. Everything is clear, it’s clear here, snakes, why they crawl. We are familiar with miracles, we know how to do them ourselves.)
Leaves. The 2nd and 10th students appear.
10th student. Smile quickly, smilebe more cheerful. We are opening our pho today tailor shop
2nd student. We are ready to beginsimple work. We can get it instantly your photo.
Invites one of the seventh graders.
10th student. This one Blank sheet ByWatch attentively. Smile more cheerfully - this is Necessarily.
2nd student. We can develop this photographI eat it easily: I sprinkle the photo with a little bullets verizer.
Invites the next one.
10th student. Again a blank sheet of paperWe have another way, a photo of the proglaWe smoke with a hot iron.
He irons the sheet and shows everyone the photo.” Invites more seventh graders.
2nd student. There is also a third way, thisNote to yourself that nothing to a piece of paperWe won't touch.
This photograph is developed under a bell in an ammonia atmosphere.
10th student. Look, can everyone see it? AThe secret is quite simple.
2nd student. Here he helped us in our workfamiliar indicator.
Shows the first picture.
They painted with acid.
Shows the second picture.
Ammonia gas.
Shows a picture under the bell.
2nd And 10th students. We are familiar with chu desami, we know how to make them ourselves.
They leave. The 4th and 3rd students appear.
3rd scientist and k., Here's another fun: whowill he give his hand to be cut off? Sorry for the handreading, then the patient is needed for treatment.
A seventh grader is invited.
4th student. We operate without pain, however,there will be a lot of blood.
3rd student. For every operation you needsterilization. Help, assistant, give me iodine!
4th student . One moment! (Gives “iodine”).
3rd student. We will moisten it with “iodine” generously,so that everything is sterile. Don't turn around, papatient, give me the knife, assistant!
Does with a knife"incision", "blood" flows.
4th student. Look, just a trickleblood flows, not water. But now I'll wipe my handku - not a trace of the cut.
- 3rd student. This Experience we explain for nowwe can’t, I’ve been promoted to ninth grade - explain We'll find some agreement.
They leave. The 5th student comes out. He reads out several verses from P. Ershov’s fairy tale “The Little Humpbacked Horse” about the firebird.
5th student. We remembered the fairy tale slightly,
about the horse, about the hunchback.
There's a firebird feather
It brought Vanya happiness.
It's time to marvel
like the firebird's feather burns.
He lights the alcohol in the cups for evaporation, the alcohol contains dissolved salts of sodium, potassium, kedah, strontium, etc. Then he covers the cups with a thick sheet of cardboard.
5th student. Answer, ninth grade, byWhy did the fire go out? Without what will the flame die? To him needed...
9th Class. Oxygen!
The 5th student leaves. The 11th student appears and places the finished model of the volcano on the table. Lights a spirit lamp, heats a glass rod
11th student. And now, friends, for youfrom history a story. Slept early at night or in the morningtownspeople, suddenly a flame appeared from the crater of the volcano. Rumble and roar, streams pour through the mouthlava. So under the lava and under the ashes he diedglorious family. I'll show you, as best I can, the death of family of Pompeii.
Touches with a heated stick, a “volcanic eruption” begins.
11th student. You guys will remember this eruption
By the way, what type of reaction is this?
9th Class. Decompositions!
All participants leave.
1st student. Our time is up.
2nd student. But we didn't show you everything,what we can do.
3rd student . We can still bend the stacklinen tubes and drill rubber plugs.
4th student. Speak chemical language.
5th student. convert copper coins into"silver".
6th student. Make a thunderstorm V test tube
7th student . Receive hydrogen and oxygen.
8th student. Explode explosive gas.
9th student. Making black powder and more much more.
10th student. This is what you will learn in bu next year.
11th student. If you are passionatestudy the most interesting science- chemistry.
Teacher. Our entertaining hour is over. In a year, seventh grade, you will be able to do all this if you want. Have you noticed that ninth graders often had to finish sentences and speak in rhyme. It's easy if you know what to say. So, now I have the same question for you that I promised to ask at the beginning of our meeting. Interesting secrets hidden in this office. I'm looking forward to seeing you next year. What will everyone tell me? I...
7th grade. I'll come"
Teacher, so come! I am waiting for you!
Target: Development of cognitive activity in the process of children's experimentation.
Tasks:
- Expanding children's understanding of the world around them through familiarization with the basic physical properties and phenomena.
- Cultivating children's interest in experimental activities.
- Creating an emotionally positive attitude in children.
Materials: plastic bottle, soda, raisins, corn kernels, balls, soda, vinegar, plastic bottle, disposable spoons, plate, milk, liquid soap, cotton swabs, paints, magnets, paper clips, cardboard, transparent containers with water, felt-tip pens, white paper napkins .
The children are met by the presenter - Wonder Woman (a group of children from 10 to 15 people).
Wonder Woman: Hello, dear guys. We are glad to welcome you to our scientific laboratory “Academy of Miracles”. Today you and I will learn how to create miracles, and at the end of the training you will receive diplomas from our academy (shows and places on the table). A robe and a cap will help us create miracles.
Children, with the help of their parents, put on robes and hats. At this time, Dyudyuka appears in the class and takes his diplomas.
Dyudyuka: Hee-hee-hee, get dressed, get dressed!.. And here are the diplomas!
Wonder Woman: Guys, it’s Dyudyuka, she took our diplomas. What to do? Dyudyuka, give us our diplomas, please!
Dyudyuka: I will give them to you only if you complete my tasks.
Wonder Woman: We will complete all the tasks, right, guys?
Dyudyuka: Well, okay. Make the raisins and corn dance.
Experience No. 1"Raisins and corn dance in soda"
For the experiment you will need: a plastic bottle, soda, raisins, corn kernels.
Pour the carbonated drink into the flask. Throw raisins and corn kernels into a flask with soda.
The result: raisins and corn kernels drown in water. But if you place them in a carbonated liquid, they will first drown, but then the gas bubbles, rising up, will carry them along with them. Having reached the surface, the bubbles burst and the corn kernels with raisins fall back to the bottom of the flask.
Dyudyuka (dissatisfied): Indeed, they are dancing. Okay, then blow up the balloon without using your mouth, using a bottle.
Wonder Woman: Guys, I know what to do.
Experience No. 2“Let’s inflate a balloon using a bottle”
For the experiment you will need: balls, soda, vinegar, plastic bottle, disposable spoons.
First to empty plastic bottle pour in about half a glass of vinegar. Then pour baking soda into the ball. Place the balloon on the neck of the bottle. Carefully and firmly holding the ball at the neck, turn it over. Baking soda falls into vinegar, and a violent storm begins chemical reaction, reminiscent of a volcanic eruption. It stands out carbon dioxide, creating pressure that inflates the balloon.
Dyudyuka: And we completed this task! But you definitely won’t be able to cope with the next one. Draw a picture without using paper.
Wonder Woman: Well, let's try.
Experience No. 3 " Drawing on milk"
For the experiment you will need: a plate, milk, liquid soap, cotton swabs and paints.
Pour milk into a plate. Add a few drops of paint into the milk. Dip cotton swabs in liquid soap and immerse them in a plate of milk.
Bottom line: when you add paint to milk, beautiful paint spills form on the surface. When liquid soap is added, the paint becomes striped and forms unexpected patterns on the surface of the milk.
Miracle Girl: And now it’s a break in our “Academy of Miracles”. I suggest a warm-up.
Musical game “The deer has a big house.”
Wonder Woman: Is everyone rested? Well, Dyudyuka, will you give us our diplomas?
Dyudyuka: I won’t think so. You haven't completed all the tasks yet. Remove the paperclip from the glass without getting your hands wet.
Experience No. 4"Get a paperclip"
For the experiment you will need: a transparent glass of water, a magnet and paper clips.
Run a magnet along the outer wall of the glass and remove the paperclip.
Dyudyuka: What?! And they did it? Well then, then... “revive” this paper clip.
Wonder Woman: Nothing is simpler!
Experience No. 5: "Live Paper Clip"
For the experiment you need: cardboard, magnet, paper clip
Place the cardboard on the magnet and a paper clip on top of the cardboard. Move the magnet and your paperclip will come to life.
Dyudyuka: I didn’t expect such smart people to study at your “Academy”. Then it will not be difficult for you to make the water flow upward and a rainbow to appear in the room.
Wonder Woman: It's simple, look...
Experience No. 6"Water Flows Up", "Rainbow"
For the experiment you will need: plastic cups with water, markers, a white paper napkin.
Make dots at the bottom of the napkin with felt-tip pens and place the tip of the napkin in the water. Before your eyes, a colorful rainbow will appear on a white napkin.
Wonder Woman: Well, Dyudyuka, are you convinced? Can our students create miracles? Give us your diplomas please.
Dyudyuka (whining): I’ll give you your diplomas, but what will be left for me?
Wonder Woman: We will give you a diploma too. Guys, training at our academy is over, let me present you with diplomas.
Graduations.
Wonder Woman: Please take off your caps and gowns, until we meet again!

- A table on which there are props and equipment necessary for experiments (special utensils and chemicals).
The target audience:
Preschoolers ( preparatory group GBDOU No. 44 Nevsky district, children school age 7-10 years.)
Scenario move: solemn music sounds. The presenter dressed as a scientist comes on stage ( white robe, glasses, hat).
Presenter: Hello guys! Welcome to the scientific laboratory, let's get acquainted! I am Professor Kolbachkina, and today we will experiment!
Do you like experiments?
Maybe some of you have already conducted some experiments?
For example, mixed porridge with soup and poured Coca-Cola over it all?
And then the most delicious experiment in the world turned out! Of course, this is a joke, today we will do real chemical experiments, and today you will become real young scientists!
And in my scientific laboratory everything is always boiling, seething, melting, smoking!
Are you ready to watch this?
Do you want to cheat yourself?
Great, but let's agree that in our laboratory we need to be careful and careful, otherwise our experiments will not work! Agreed?
Tell me, what famous chemist scientists do you know?
Today we will see a key that can make sounds, show you unusual soap bubbles, call up a winter blizzard, and also watch how the chemical porridge cooks on its own... So, are you ready?
Now tell me, what time of year is it now?
What season follows autumn?
Now I suggest everyone close their eyes and imagine that the real world has arrived. Cold winter! What do you see outside in winter? Snowing?
And what covered all the puddles, rivers, lakes? Of course, ice! Now let's open our eyes...
Guys, who knows what ice is?
How can water be turned into ice?
Is it possible to make ice from juice?
Yes, and it will turn out to be fruity ice, like ice cream...
Is it possible to make ice from soup? You can, and you’ll end up with a soup that you can’t eat!
And now a question for the smartest: is it possible to make ice from thin air? And from carbon dioxide?
Guys, we inhale oxygen and exhale carbon dioxide. And yesterday I breathed, breathed and inhaled a whole bucket of carbon dioxide, and then decided to freeze it! What do you think I did? What's inside the bucket?
(The presenter shows a bucket covered with a handkerchief on top)
Now let's listen (shakes the bucket). Yes, something hard...(opens the pot).
It's ice! (shows a piece of ice)
But the ice is unusual! It's dry ice! Do you see a slight smoke coming out of it? He's melting! Only it turns not into water, but into carbon dioxide! That’s why it’s called “Dry Ice”! What is the temperature of this ice? (-79 degrees). This is the coldest ice in the world, so you can only handle it with gloves! Agreed?
Now tell me what I have in my hands?(shows key)
Can the keys talk and sing songs? Of course not! Now let's see otherwise! So, let's listen carefully...
(Places a piece of ice against the key, the audience hears ringing sound(squeaking)).
Let's figure out where this sound comes from? Can the key really beep? Of course not. What kind of ice do we always have?.. Cold! And the key was warm, so what is it like?.. Warm! We lean the warm key against the ice, the ice begins to melt, bubbles of carbon dioxide fly out and quickly knock on the key, which is why we hear such a sound!
The next experiment will be carried out by you! To do this you need to wear gloves(children are given gloves).Who will read us the task on the card that needs to be completed?(children read “Call a Winter Blizzard”)
How can we cause a blizzard, because we don’t even have snow, and if we had it it would have melted long ago! Let's get down to science!
So, I invite four people here who want to participate in the experiment!
How should I call you? How your name and middle name?(child says his name)
So, you are our scientist...(calls by name and patronymic. He asks other children in the same way and calls him a professor, scientist, experimenter...)
Now we'll pour hot water on a tray, take a piece of ice and throw it into the water. Ready... Let's throw!(Children observe cold white smoke)
Now look where is he going Is the smoke up or down? Yes, it goes down, but do you know why? Because our smoke is heavier than air, and like any heavy object it falls down!
Well done boys! Let's applaud our young scientists, this is their first scientific discovery!
Now answer the question: what happens if you put a pot of ice in the coldest freezer in the world and leave it overnight? Will there be even more ice? Will everything be covered in snow? In fact, nothing will happen! The ice will evaporate and will not leave a trace behind! It melts so quickly!
Who will read the next assignment? (Children read: “Call the Genie from the Flask”)
Have you guys ever called Gene? As you know, the Genie lives in a lamp. Now tell me what I have in my hands? Is this a bottle? Or a vase? Or a decanter?
No, it's a flask! Scientists need a flask to mix different liquids and conduct experiments. We will use this flask to conduct our experiment. I now invite the next four participants.
Now pour hot water into the flask(pours water). Tell me, has the water boiled?
(shows the children a flask with bubbling water?)Of course not! After all, there is ice inside it, and it does not heat the water, but, on the contrary, cools it, and the water boils because bubbles of carbon dioxide instantly escape from pieces of ice melting in the hot water!
Guys, who is in favor of adding Blue colour? Who likes red better? Add the selected color to the flask!(children add dye).
Now add pieces of ice inside the flask(children add ice, observe a column of smoke and bubbling water in the flask)
Now let’s make wishes, and the Genie sitting in the flask must make them come true! To make your wishes come true, you need to rub the flask, but not to the hole, and you can also listen to the Genie talk in his seething tongue!
(The presenter walks through the audience, the children make wishes, listen to the sounds emanating from the flask)
Guys, there are still many experiments in our laboratory! For example, have you ever seen a self-inflating soap bubble? Would you like to see such a soap bubble? Tell me, what are soap bubbles made of?
What's inside each soap bubble?(Air)
So, look carefully, the experiment is very complicated! Tell me what's in my hands? (Shows liquid soap) Now I will lubricate the edges of the container with this soap.(lubricates the edges of the container with liquid soap)
IN this experience precision is needed, not a single drop of soap should get inside the container, otherwise the experiment may not work! Chemistry is generally an exact science!
Our soap bubble is very capricious!
Now I pour hot water into the container, and then cold water. What kind of water do I get?(Warm)
Now I put the pieces of ice in the water, very carefully so as not to splash the water, and then I pull the soap film with a washed cloth!(Using a soap rag, the presenter pulls the soap film, passing it along the top of the container. As a result, the children watch how the soap bubble begins to grow.)
How did he grow on his own? Let's figure it out. We put ice in the water, and white smoke began to emerge, then we ran a washed cloth over the top of the container, forming a soapy film. As a result, the film tightened, and our smoke, escaping, began to stretch it more and more, that’s how we saw a soap bubble that itself was growing before our eyes!
And our soap bubble can dance and jump!(The presenter spins the container in a circle, then up and down, then the bubble bursts, the smoke spreads out in a wave from top to bottom).
Guys, in every experiment we use a substance such as water. Do you know what is made of water and what is not? Let's check this now. Have your palms ready. If I call something that consists of water, you clap, for example, tea, it consists of water…. If I name something that is not made of water, you raise your hands up. Agreed? So…
Tea, kettle, snow, snowman, ocean, cockroach, candy, cutlet, river, stove... Socks, wet socks?
Well done! For the next competition we will also need water. We will pour it into this vessel.(Shows the bottle).What is it called?(Bottle.) (Pours hot water into the bottle)
So, hot water in a bottle. Now the next four participants come to me. Introduce youreself…(Children say their names)
Add a piece of ice to the bottle and sit down.
(Children add ice to the bottle).
Look what a carbonated drink we made! Have you ever inflated balloons using a bottle? Let's try!(Puts the ball on the bottle, the ball begins to grow).
Now let's make wishes again! If the ball flies, your wishes will definitely come true! So, let's launch!(The presenter removes the ball from the bottle, launches it, it flies, releasing smoke)
Tell me what's in my hands (Shows the pipe). Is this an elephant's trunk? Or a snake? Or maybe it's someone's tail? Of course it's a pipe! But she is unusual. She's musical! I invite three participants. You will be musicians. Twist this pipe in a circle.(Children spin, unusual sounds are heard).It turns out that you can play on such a trumpet too! In fact, when we untwist the pipe, a stream of air gets inside, hits the walls, which begin to vibrate, shaking the air inside, it also begins to vibrate, and this is the vibration we hear!
Now let's try to make unusual soap bubbles! They will white, and stick to my palm!
To do this, we will pour hot water into the jars. And the next assistants will add ice. I will ask the four participants to come to me.(Children add ice to the jar)We have water with soap and glycerin poured into a glass; it just makes soap bubbles more durable.
Now we attach the pipe to the jar, lower its tip into a glass of soapy water and... Soap bubble on our palm (Blows a soap bubble onto the palm, it is held on the palm)
These unusual soap bubbles can be made using dry ice!
And one more experiment: tell me, does everyone eat porridge in the morning? Who eats semolina porridge, Hands up! Who loves rice porridge? Who prefers buckwheat? Hercules? Soapy? Oh, does such a mess happen? Can the porridge itself cook? Let's do it like in the fairy tale about the pot of porridge... Remember, in this fairy tale, the pot cooked porridge and made so much of it that it flowed through the streets, between the houses, and the whole city was able to eat up this porridge... And the pot kept cooking and cooking. I want to cook the same porridge! Will you help me? Then I invite the next six participants! So, we don’t have a saucepan, but we do have a pot. We will add water to it, because without it you cannot cook porridge! Now let's add soap grits. Add! Let's count everything together... One, two, three...
(Children add several servings of soap to count)
Now we take pieces of ice and throw them on the count of “Three”... One, two, three...
(Children watch the soapy mess)
Now let's say "Don't cook the pot"!
No, guys, this is not a fairy tale, but science, and the pot will cook while it goes on. physical reaction, and until all the ice melts!
Guys, today we conducted various experiments. Which experiment did you like best? What is frozen carbon dioxide called? (Dry ice)
What is his temperature, who remembers? (-79 degrees)
Does it evaporate quickly or not? (Fast)
Is it possible to blow a soap bubble with it? balloon? (Can)
What do we see when it melts? (White smoke)
Did you like the experiments? Do you want to become a scientist in the future?
I want to wish you new knowledge, good grades in school, master science! And remember, science is not only useful, but also very interesting! See you again!

Progress of entertainment:
Hello children! My name is Associate Professor Pochemuchkina (DP). Today I invite you to my scientific laboratory. Do you know what a laboratory is? (Children answer)
What smart guys you are, yes, a laboratory is a special place where experiments are carried out. Oh, do you like to experiment? (Children answer)
Today we will do this exciting activity together with you. Just to get started, let’s remember the safety rules:
PROHIBITED WITHOUT PERMISSION
Get up from your seat
Touch equipment, devices and reagents
Putting something in your nose, mouth, ears, etc.
Tell me, children, why do scientists conduct experiments and experiments? (Children answer)
Of course, scientists want to unravel the mysteries of nature. And for you I have the first riddle: what is there a lot in this room, but we don’t see it? (Children answer)
Now we will conduct such an experiment that everyone will be able to see the answer.
I need two assistants.
(He selects two children from the audience and invites them to blow through straws into a jar of water. While the children are blowing, the child asks questions to the audience.)
What do we see? (Children: Air bubbles, air)
Where does this air come from? (Children: Children inhale it and exhale through a straw)
Where do the air bubbles go? (Children: They float up from under the water, and the air returns to the hall)
Why don't the bubbles stay in the water? (Children: Because air is lighter than water)
Yes, air is lighter than water. This has been confirmed by many experiments. We will conduct one of them today.
What color is the air? (Children: None, the air is clear)
Can you hear the air? (Children: you can hear the wind, a blizzard, musical wind instruments. DP invites one child to inflate a balloon, and then releases air from the balloon through the gap so that a sound is made. Children laugh).
What do we hear? (Children: Air)
I suggest you get acquainted with one more property of air. To do this, let's conduct an experiment - heat the air and then cool it.
The teacher invites the child to put the ball on the neck of the bottle; puts the bottle in a container with hot water, the ball is filled warm air and takes the form of a mushroom; lets children make sure the water is hot; places the bottle in a container with cold water; lets children make sure the water is cold; the air in the bottle and the ball cools, and the ball is drawn into the neck of the bottle; children try to pull the ball out of the neck of the bottle, but they fail; children help explain what happens to the air during the experiment).
Having heated up, the air expanded, there was more of it, and it inflated the balloon. When the air cooled, it contracted, there was so little of it that the ball was drawn into the bottle. So, when air is heated, it expands, and when cooled, it contracts.
(Children repeat this property of air, accompanying the words with movements: for words - expands - stand up, arms to the sides, for words narrows - sit down, lower your head, pull up your knees and hug them with your hands).
Another question about the properties of air - what does the air smell like? (Children answer. The teacher encourages them to name different smells and aromas, asks what the air smells like in the village, in the city, in the forest, in the kitchen, etc., what it smells like in this room.)
DP: Why do we need water? Where she lives? She is alive? (Listens to the children’s answers.)
Does water have a color? (No, it is colorless.) Could it become colored? What needs to be done for this? (Add paint. DP does what the children say.) Does water have a smell? (They sniff the water, make sure that it doesn’t smell of anything.) What can be done to make the smell appear (Brew tea, coffee, dissolve jam.) What does the water taste like? (Tasteless.) What if you throw salt, sugar, pepper, and a slice of lemon into it? Let's play a little. We will all be droplets. Let's stand in a circle and hold hands tightly. Let's imagine that it has become very cold. What have we turned into (Into ice.) Yes, we have become solid. Now let’s run in different directions and imagine that spring has come. What have we become? (Into droplets.) And then the droplets gathered together again and became streams that quickly, quickly ran into rivers, seas, and oceans. So what can water do? (Flow)
You guys probably conducted experiments in your group on the buoyancy of objects. Let's play the sink-swim game. I will show the object, and you show it, if it’s drowning, sit on the chairs and say “glug-glug-glug”; if it floats, stand up, row with your hands and say “splash-splash-splash.”
(The game “Sinking and Swimming” is played; real objects, pictures or images on a multimedia screen can be used for demonstration).
I know another very interesting experience on buoyancy, many of you are regular participants. Raise your hands how many of you like to swim? (Children raise their hands). Tell me where are you swimming? (Children: in the pool, on the river, in the sea, in the lake, on the pond). Where is it easiest to swim? (Children: at sea). And why? (Children: the water in the sea is salty, it holds better). Absolutely true, my friends, and we will confirm this with you with the next experiment. (In one jar - plain water, and salt is added to the other. In fresh water, the egg sinks, and in salt water, it floats. Adding salt to the jar, then fresh water, DP forces the egg to float up and then sink to the bottom of the jar, and ensures that the egg hangs in the middle of it. Children actively help in conducting the experiment).
At the end of our meeting, I suggest you create a volcano! No, a volcano is not allowed, safety precautions do not allow it... Then - a water volcano, i.e. a geyser! My assistants have already constructed a crater (they take out a model of a geyser, all that remains is to activate it!
The teacher invites those interested, the children pour soda and citric acid into the crater, the DP pours water into the crater and the audience gasps in surprise - the geyser spews out an effervescent fountain).
Now let's sum up the results of today's meeting. What did you, my friends, like today, what surprised you, what did you learn today, what new things did you learn? (Children answer)
Our journey into the world of experiences and experiments does not end here. I wish you to continue it together with your teachers and parents! Observe the world around you, ask questions and wonder, experiment and discover the laws of nature and the universe! See you again, friends!(Music from the program “Obvious-Incredible” sounds. DP says goodbye to the guests)

In our work, we use several options for a show program for a children's party. Much in this case depends on how much time you are willing to devote to the performance of chemical artists. For example,Chemical SHOWfor a birthday according to the program"Mini" or "Economy" ideal for a celebration where not many children are invited or they small age. Within one performance, they will be exposed to a sufficient number of different experiences, and the succinctly written script will give them a lot of pleasure. A great addition to such a program would be thoughtful animation. All this is inexpensive and spectacularly diversifies the monotonous holidays that are already boring to many. Chemical SHOW can rightfully be considered an excellent choice and it is very reckless to miss the opportunity to use it to entertain your children.
For events with big amount guests and participants, we usually offer programs"Standard" and "Premium" . Their key difference is that the script contains much more experiments and mass action, in which almost everyone can take part. If you have been looking for a SHOW on New Year or any other major event at school and kindergarten, our offer is exactly what you need. We can even help with open lesson in Chemistry and Physics
The chemical show is strikingly different from anything you've ever seen before.
