Do you have questions?

If you're wondering how to celebrate a child's birthday, you might like the idea of ​​putting on a children's science show. In recent years, scientific holidays have become increasingly popular. Almost all children like entertaining experiments and experiments. For them, this is something magical and incomprehensible, which means interesting. The cost of hosting a science show is quite high. But this is no reason to deny yourself the pleasure of watching the astonished children's faces. After all, you can manage on your own, do not resort to the help of animators and holiday agencies.

In this article, I made a selection of simple chemical and physical experiments and experiments that can be done at home without any problems. Everything you need to carry them out is probably in your kitchen or first aid kit. You don't need any special skills either. All you need is a desire and a good mood.

I tried to collect simple but spectacular experiences that will be of interest to children of different ages. For each experiment, I prepared a scientific explanation (not for nothing that I studied to be a chemist!). To explain to the children the essence of what is happening or not is up to you. It all depends on their age and level of training. If the children are small, you can skip the explanation and go straight to the spectacular experience, saying only that they will be able to learn the secrets of such “miracles” when they grow up, go to school and begin to study chemistry and physics. Perhaps this will arouse their interest in studying in the future.

Although I chose the safest experiments, they still need to be taken very seriously. All manipulations are best performed with gloves and a bathrobe, at a safe distance from children. After all, the same vinegar and potassium permanganate can cause trouble.

And, of course, when conducting a children's science show, you need to take care of the image of a mad scientist. Your artistry and charisma will largely determine the success of the event. Turning from an ordinary person into a funny scientific genius is not at all difficult - all you need to do is ruffle your hair, put on big glasses and a white coat, smear yourself with soot and make an expression corresponding to your new status. This is what a typical mad scientist looks like.

Before you arrange a science show at a children's holiday (by the way, it can be not only a birthday, but any other holiday), you should do all the experiments in the absence of children. Rehearse that there were no unpleasant surprises later. Few things can go wrong.

Children's experiments can be carried out without a festive occasion - just so that it is interesting and useful to spend time with a child.

Choose the experiences you like the most and write a script for the holiday. In order not to heavily burden children with science, albeit entertaining, dilute the event with fun games.

Part 1. Chemical show

Attention! When conducting chemical experiments, you should be extremely careful.

foam fountain

Almost all children love foam - the more the better. Even kids know how to make it: for this you need to pour shampoo into water and shake it well. But can the foam form by itself without shaking and be also colored?

Ask the children what they think foam is. What is it made of and how can it be obtained. Let them express their guesses.

Then explain that foam is bubbles filled with gas. This means that for its formation, some substance is needed, of which the walls of the bubbles will consist, and a gas that will fill them. For example, soap and air. When soap is added to water and stirred, air enters these bubbles from the environment. But gas can be obtained in another way - in the process of a chemical reaction.

Option 1

  • hydroperite tablets;
  • potassium permanganate;
  • liquid soap;
  • water;
  • a glass vessel with a narrow neck (preferably beautiful);
  • cup;
  • a hammer;
  • tray.

Statement of experience

  1. Using a hammer, crush the hydroperite tablets into powder and pour it into a flask.
  2. Place the flask on the tray.
  3. Add liquid soap and water.
  4. Prepare an aqueous solution of potassium permanganate in a glass and pour it into a flask with hydroperide.

After the solutions of potassium permanganate (potassium permanganate) and hydroperide (hydrogen peroxide) merge, a reaction will begin to occur between them, accompanied by the release of oxygen.

4KMnO 4 + 4H 2 O 2 = 4MnO 2 ¯ + 5O 2 + 2H 2 O + 4KOH

Under the action of oxygen, the soap present in the flask will begin to foam and lick out of the flask, forming a kind of fountain. Due to potassium permanganate, part of the foam will turn pink.

You can see how this happens in the video.

Important: the glass vessel must have a narrow neck. Do not take the resulting foam in your hands and do not give it to children.

Option 2

Another gas, such as carbon dioxide, is also suitable for the formation of foam. You can paint the foam in any color you wish.

For the experiment you will need:

  • plastic bottle;
  • soda;
  • vinegar;
  • food coloring;
  • liquid soap.

Statement of experience

  1. Pour into a bottle of vinegar.
  2. Add liquid soap and food coloring.
  3. Pour in soda.

Result and scientific explanation

When soda and vinegar interact, a violent chemical reaction occurs, accompanied by the release of carbon dioxide CO 2.

Under its action, the soap will begin to foam and lick out of the bottle. The dye will color the foam in the color you choose.

Merry ball

What's a birthday without balloons? Show the children the balloon and ask how to inflate it. The guys, of course, will answer that by mouth. Explain that the balloon is inflated by the carbon dioxide we exhale. But you can inflate the balloon with them in another way.

For the experiment you will need:

  • soda;
  • vinegar;
  • bottle;
  • balloon.

Statement of experience

  1. Pour a teaspoon of baking soda into the balloon.
  2. Pour into a bottle of vinegar.
  3. Put the ball on the neck of the bottle and pour the soda into the bottle.

Result and scientific explanation

As soon as baking soda and vinegar come into contact, a violent chemical reaction will begin, accompanied by the release of carbon dioxide CO 2 . The balloon will begin to inflate before your eyes.

CH 3 -COOH + Na + - → CH 3 -COO - Na + + H 2 O + CO 2

If you take a smiley balloon, it will impress the guys even more. At the end of the experiment, tie a balloon and give it to the birthday person.

See the video for a demonstration of the experience.

Chameleon

Can liquids change their color? If yes, why and how? Before setting up an experiment, be sure to ask the children these questions. Let them think. They will remember how water is colored when you rinse a brush with paint in it. Is it possible to decolorize the solution?

For the experiment you will need:

  • starch;
  • alcohol burner;
  • test tube;
  • cup;
  • water.

Statement of experience

  1. Pour a pinch of starch into a test tube and add water.
  2. Drop some iodine. The solution will turn blue.
  3. Light the burner.
  4. Heat the test tube until the solution becomes colorless.
  5. Pour into a glass of cold water and immerse the test tube into it so that the solution cools down and turns blue again.

Result and scientific explanation

When interacting with iodine, the starch solution turns blue, since a dark blue compound I 2 * (C 6 H 10 O 5) n is formed. However, this substance is unstable and, when heated, again decomposes into iodine and starch. When cooled, the reaction goes in the opposite direction and we again see how the solution turns blue. This reaction demonstrates the reversibility of chemical processes and their dependence on temperature.

I 2 + (C 6 H 10 O 5) n => I 2 * (C 6 H 10 O 5) n

(iodine - yellow) (starch - clear) (dark blue)

rubber egg

All children know that the eggshell is very fragile and can break from the slightest blow. It would be nice if the eggs didn't beat! Then you wouldn't have to worry about bringing the eggs home when your mom sends you to the store.

For the experiment you will need:

  • vinegar;
  • raw chicken egg;
  • cup.

Statement of experience

  1. To surprise the kids, you need to prepare for this experience in advance. 3 days before the holiday, pour vinegar into a glass and place a raw chicken egg in it. Leave for three days so that the shell has time to completely dissolve.
  2. Show the children a glass with an egg and invite everyone to say a magic spell together: “Tryn-dyryn, boom-brown! Egg, become rubber!
  3. Take out the egg with a spoon, wipe it with a napkin and demonstrate how it can now be deformed.

Result and scientific explanation

Eggshells are made up of calcium carbonate, which dissolves when reacted with vinegar.

CaCO 3 + 2 CH 3 COOH \u003d Ca (CH 3 COO) 2 + H 2 O + CO 2

Due to the presence of a film between the shell and the contents of the egg, it retains its shape. What an egg looks like after vinegar, look at the video.

Secret letter

Children love everything mysterious, and therefore this experiment will surely seem like real magic to them.

Take an ordinary ballpoint pen and write on a piece of paper a secret message from aliens or draw some kind of secret sign that no one but the guys present can know about.

When the children read what is written there, say that it is a big secret and the inscription must be destroyed. Moreover, magical water will help you erase the inscription. If you treat the inscription with a solution of potassium permanganate and vinegar, then with hydrogen peroxide, the ink will be washed off.

For the experiment you will need:

  • potassium permanganate;
  • vinegar;
  • hydrogen peroxide;
  • flask;
  • cotton buds;
  • ball pen;
  • paper;
  • water;
  • paper towels or napkins;
  • iron.

Statement of experience

  1. Draw a picture or an inscription on a sheet of paper with a ballpoint pen.
  2. Pour a little potassium permanganate into a test tube and add vinegar.
  3. Soak a cotton swab in this solution and swipe over the inscription.
  4. Take another cotton swab, moisten it with water and wash off the resulting stains.
  5. Blot with a tissue.
  6. Apply hydrogen peroxide to the inscription and blot again with a napkin.
  7. Iron with an iron or put under a press.

Result and scientific explanation

After all the manipulations, you will get a blank sheet of paper, which will surprise the children very much.

Potassium permanganate is a very strong oxidizing agent, especially if the reaction occurs in an acidic environment:

MnO 4 ˉ+ 8 H + + 5 eˉ = Mn 2+ + 4 H 2 O

A strong acidified solution of potassium permanganate literally burns many organic compounds, turning them into carbon dioxide and water. Acetic acid is used to create an acidic environment in our experiment.

The product of the reduction of potassium permanganate is manganese dioxide Mn0 2, which has a brown color and precipitates. To remove it, we use hydrogen peroxide H 2 O 2 , which reduces the insoluble compound Mn0 2 to a highly soluble manganese (II) salt.

MnO 2 + H 2 O 2 + 2 H + = O 2 + Mn 2+ + 2 H 2 O.

I propose to see how the ink disappears on the video.

The power of thought

Before setting up the experiment, ask the children how to put out the candle flame. They, of course, will answer you that you need to blow out the candle. Ask if they believe you can put out a fire with an empty glass by casting a magic spell?

For the experiment you will need:

  • vinegar;
  • soda;
  • glasses;
  • candles;
  • matches.

Statement of experience

  1. Pour soda into a glass and pour vinegar over it.
  2. Light some candles.
  3. Bring a glass of soda and vinegar to another glass, tilting it slightly so that the carbon dioxide produced during the chemical reaction flows into the empty glass.
  4. Carry a glass of gas over the candles, as if pouring them over the flame. At the same time, make a mysterious expression on your face and say some incomprehensible spell, for example: “Chicken-burs, mur-plee! Flame, don't burn anymore!" Children must think it's magic. You will reveal the secret after the enthusiasm.

Result and scientific explanation

When baking soda and vinegar interact, carbon dioxide is released, which, unlike oxygen, does not support combustion:

CH 3 -COOH + Na + - → CH 3 -COO - Na + + H 2 O + CO 2

CO 2 is heavier than air, and therefore does not fly up, but settles down. Thanks to this property, we are able to collect it in an empty glass, and then “pour it” onto candles, thereby extinguishing their flame.

How it happens, look at the video.

Part 2. Entertaining physical experiments

strong jean

This experiment will allow children to look at the usual action for them from the other side. Place an empty wine bottle in front of the children (it is better to remove the label first) and push the cork into it. And then turn the bottle upside down and try to pop the cork out. Of course, you won't succeed. Ask the children if there is any way to get the cork out without breaking the bottle? Let them say what they think about it.

Since the cork cannot be picked up through the neck, it means that one thing remains - to try to push it out from the inside out. How to do it? You can call the genie for help!

The genie in this experiment will be a large plastic bag. To heighten the effect, the package can be painted with colored markers - draw eyes, nose, mouth, pens, some patterns.

So, for the experiment you will need:

  • empty wine bottle;
  • cork;
  • plastic bag.

Statement of experience

  1. Twist the bag with a tube and put it into the bottle so that the handles are outside.
  2. Turning the bottle over, ensure that the cork is on the side of the package closer to the neck.
  3. Inflate the package.
  4. Gently begin to pull the bag out of the bottle. A cork will come out with it.

Result and scientific explanation

As the bag inflates, it expands inside the bottle, expelling air from the bottle. When we begin to pull out the bag, a vacuum is created inside the bottle, due to which the walls of the bag wrap around the cork and drag it out with them. This is such a strong gin!

To see how this happens, watch the video.

Wrong glass

On the eve of the experiment, ask the children what happens if you turn a glass of water upside down. They will answer that the water will pour out. Say that this happens only with the "correct" glasses. And you have a “wrong” glass from which water does not pour out.

For the experiment you will need:

  • glasses with water;
  • paints (you can do without them, but this way the experience looks more spectacular; it is better to use acrylic paints - they give more saturated colors);
  • paper.

Statement of experience

  1. Pour into glasses of water.
  2. Add color to it.
  3. Moisten the rims of the glasses with water and place a sheet of paper over them.
  4. Press the paper firmly against the glass, holding it with your hand, turn the glasses upside down.
  5. Wait for a while until the paper sticks to the glass.
  6. Remove your hand quickly.

Result and scientific explanation

Surely all children know that we are surrounded by air. Although we do not see him, he, like everything around him, has weight. We feel the touch of air, for example, when the wind blows on us. There is a lot of air, and therefore it presses on the earth and everything that is around. This is called atmospheric pressure.

When we apply paper to a wet glass, it sticks to its walls due to surface tension.

In an inverted glass, between its bottom (now at the top) and the surface of the water, a space is formed filled with air and water vapor. The force of gravity acts on the water, which pulls it down. This increases the space between the bottom of the glass and the surface of the water. At constant temperature, the pressure in it decreases and becomes less than atmospheric. The total pressure of air and water on the paper from the inside is slightly less than the air pressure from the outside. Therefore, water does not pour out of the glass. However, after a while, the glass will lose its magical properties, and the water will still pour out. This is due to the evaporation of water, which increases the pressure inside the glass. When it becomes more than atmospheric, the paper will fall off and the water will pour out. But you can't bring it up to this point. So it will be more interesting.

You can watch the progress of the experiment on the video.

Gluttonous bottle

Ask the children if they like to eat. Do they like to eat glass bottles? Not? Bottles are not eaten? And here they are wrong. They don’t eat ordinary bottles, but magic bottles are not even averse to having a bite.

For the experiment you will need:

  • boiled chicken egg;
  • a bottle (to heighten the effect, the bottle can be painted or somehow embellished, but so that the children can see what is happening inside it);
  • matches;
  • paper.

Statement of experience

  1. Peel off the shell of the boiled egg. Who eats eggs in shell?
  2. Set fire to a piece of paper.
  3. Throw the burning paper into the bottle.
  4. Put the egg on the neck of the bottle.

Result and scientific explanation

When we throw burning paper into the bottle, the air in it heats up and expands. By closing the neck with an egg, we prevent the flow of air, as a result of which the fire goes out. The air in the bottle cools and contracts. A pressure difference is created inside the bottle and outside, due to which the egg is sucked into the bottle.

For now, that's all. However, over time, I plan to add a few more experiments to the article. At home, you can, for example, experiment with balloons. Therefore, if you are interested in this topic, add the site to your bookmarks or subscribe to the newsletter. When I add something new, I will inform you about it by e-mail. It took me a lot of time to prepare this article, so please respect my work and when copying materials, be sure to put an active hyperlink to this page.

If you have ever done home experiments for children and put on a science show, write about your impressions in the comments, attach a photo. It will be interesting!

Does your child have a birthday? Are you looking for a clown and balloons? Are you sure that it will be interesting for children? Now I'm starting to doubt! Of course, a talented clown is able to surprise and make even adults laugh. But let's come up with something more original and at the same time useful and educational for the children's holiday!

The wonders of science, fun experiments, a magical laboratory with funny scientists - all this will certainly arouse children's interest! Create an educational holiday for the children with real scientific experiments that are absolutely safe and so exciting. Recommended children's birthday scenario for children 7-12 years old.

Thematic design of a children's holiday

To decorate a children's holiday, we will choose the brightest colors and icons, symbols from a chemistry textbook associated with science, an experimental laboratory. And, of course, for decoration we need toy white mice, test tubes,

When decorating the table, it is better to give preference to unusual snacks and desserts: blue and green drinks, colored jelly, bags of marmalade of the most unusual shapes.

As an invitation, you can take the idea of ​​a nominal pass to a secret laboratory. Children will also be happy if they are given a uniform and initiation into secret scientists.

Games and entertainment for the children's holiday Little Einsteins

To realize the idea of ​​a holiday with scientific experiments, it is best to invite animators with a suitable program. But you can also purchase a ready-made kit for experiments that can be carried out with children.

Parents can be the facilitators and play the role of eccentric scientists. You will need a white coat, glasses and a suitcase with props. You can add a mustache like Einstein and a funny giant watch on a chain to the image.

You can divide this time into 3 parts:

An exciting one-hour program with fun experiments, scientific discoveries, in which your children will participate;

Outdoor games;

Delicious change.

You can start the program by initiating children into the secret employees of the experimental laboratory. The tests may include: a quiz on the topic of various natural phenomena, learning and performing a dance in which the secret code for opening the laboratory is encrypted. It can be interesting for children to solve charades and puzzles, build logical chains, as well as active ball games "Edible - not edible", and, of course, participation in real experiments.

Scientific experiments and experiments for children at home

We mix liquids of different densities and colors.

Pour 1 part water, 1 part sunflower oil, 1 part bright-colored syrup. Children can watch the magical distribution of liquid in layers.

Use ready-made kits for conducting such scientific experiments for children. The holiday will turn out not only fun, but also educational!

Do not forget about the photographer for the children's party, who will capture this unusually fun and interesting day as a keepsake.

May 31, 2017

A science-style party is a great idea for a child's birthday, where the birthday boy and his guests will be able to make new discoveries and conduct interesting experiments. These are not only positive impressions, but also useful knowledge that children will learn with pleasure.

It is erroneously believed that only teenagers may be interested in this kind of holidays, but this is not so. Children, starting from 4 years old, will like such a party, because this is just the age of active knowledge of the world.

Science shows are not just memorizing formulas and stating facts. This is an exciting process that is somewhat similar to a game where everyone is an active participant.

Therefore, feel free to choose a science party that will cause genuine delight in children, introduce chemistry and physics in an interesting way, and in a good scenario, it may have a beneficial effect on the cognitive activity of the child.

To organize a holiday, many turn to professionals for help. But their work costs money, and often a lot. But it's not even about money: experiments performed by parents, and not by strangers, will have a completely different effect. Yes, and you yourself will get a lot of pleasure from the process of preparation and the very triumph of science.

1. Preparing for a Science Party

First you need to send out letters to all guests with an invitation to the holiday. To do this, you can send both a paper version and use e-mail. The second method will be less energy-consuming and in the spirit of the times, because now almost all children have their own electronic boxes.

It is important that the text of the letter be as formal as possible. It is worth addressing the guest by name and patronymic. You can use the appeals "doctor of science", "scientist", "candidate of science", "professor".

Make special badges in advance with photos of the kids, surnames and initials. With their help, it will be possible to make a meeting of guests as at a serious scientific conference. In invitation cards, ask to take a white coat with you, because in a scientific laboratory there is no way without a dressing gown. If this element of the wardrobe is tense, white men's shirts are quite suitable.

2. Party decoration in a scientific style

The walls of the room can be decorated with posters of your own making, on which various mathematical, physical and chemical formulas will be written. Use portraits of famous scientists with their inventions. Various graphs, drawings and diagrams will look great.

It is worth taking care to create two zones: for a feast and for experiments. These two zones cannot be too close to each other for safety reasons - you never know what can get into the food during the demonstration of experiments.

The table can be decorated in a scientific style. For example, serve compote not in a jug, but in a large flask. And instead of glasses, use beakers or even test tubes. Someone will say that drinking from them will not be very convenient. The problem is solved by using cocktail tubes. Snacks can be made in the form of small multi-colored tablets.

Give your dishes themed names such as Essence of Power, Truth Serum, Big Bang, Chemical Reaction, and more. Print out the name on paper, and attach it to a skewer like a flag. Insert the named skewers into the dishes.

3. Science experiments for a party

Decoration and food are good, but the highlight of the program will be various experiences. They should be:

  • interesting;
  • not requiring complex ingredients;
  • not requiring long-term preparation;
  • limited in time (children will not wait long);
  • safe (and this is the main condition).

It is important to remember that experience must not only be shown, but also explained in an accessible way. Otherwise, it will just look like a focus. And do not forget that a science party will only be successful when the children actively participate in all the proposed experiments.

Experience No. 1 "Purple Milk"

You will need:

  • transparent glass;
  • water;
  • potato starch;
  • a spoon;

Precautionary measures:

  1. The adult must ensure that the children do not drink or eat any of the demonstration components during the experiment.
  2. In order not to smear clothes and hands, it is better to use gloves and an apron.

Experience progress:

Water is poured into a glass. Then 1 tablespoon of potato starch is added there and mixed well. After that, the water will turn white, similar to milk. The next step is to add iodine to the liquid. To do this, you can also use a spoon, or you can simply pour it into a glass from a bubble.

If everything is done correctly, the liquid in the glass will instantly turn purple.

Experience No. 2 "Rainbow in a glass"

For experience you will need:

  • cup;
  • water;
  • colored markers or felt-tip pens;
  • paper towel;
  • scissors.

Precautionary measures:

  1. Make sure that children do not get hurt by scissors. And best of all, volunteer to be their assistant and do all the manipulations with the scissors yourself.

Experience progress:

Fill the glass 1/4 full with water. Let's set it aside. Next, take a paper towel and cut out of it a strip 3 cm wide and 10-15 cm long. We don't need scissors anymore. Now we take the markers (it is better if they match the colors of the rainbow) and begins to put dots on the strip on one side horizontally. The points should be placed close to each other and show through to the other side of the strip. In order to make a rainbow, the colors must go in a known order. As a matter of fact, on this all the preparatory work is over. It remains only to immerse the strip in the water with the side on which the dots were applied. After this simple manipulation, the rainbow on the paper will begin to rapidly rise upwards.

Such an experience will help the children visually see the process of water absorption by a solid body.

Experience No. 3 "Flying porridge"

For experience you will need:

  • plate;
  • cereals;
  • balloon;
  • threads.

Experience progress:

Spread oatmeal on a plate in a thin layer. Inflate a balloon and tie it. Now rub the ball against your hair. We do it well and diligently. And then we bring it to the plate and, together with the children, we observe how the cereal begins to take off from the plate and stick to the ball. This is a very simple, safe and at the same time effective experiment.

Experience No. 4 "Orange divers"

You will need:

  • 3 oranges;
  • water;
  • transparent wide vase about 50 cm high.

Precautions: in general, the experiment is absolutely safe for children, but since during the experiment they will have to deal with water, it is better to put oilcloth aprons on them.

Experience progress:

Fill a clear vase 2/3 full with water. Next, one of the children is invited to dip 1 orange into a container of water to check whether it will drown or not. Orange, as you understand, will float on the surface. Next, the young experimenter is invited to remove the entire peel from the same orange and put it back into the vase (suddenly the citrus does not want to bathe dressed). When the peel is removed and the fruit has gone into the water, you can see how it goes to the bottom. So let's keep experimenting. We take another orange and remove only 2/3 of the peel from it. The child lowers it into the water, and everyone present can observe how it hangs exactly in the middle between the bottom and the surface of the water. And to complete the composition, let's drop the third orange into the vase untouched. It will become a bright point of the experiment.

Experience No. 5 "Invisible Stick"

You will need:

  • 3 tall glasses;
  • 3 glass sticks;
  • water;
  • vegetable oil (preferably unrefined).

Precautions: All you need is aprons and gloves.

Experience progress:

At the beginning, ordinary water is poured into one of the glasses. A glass rod is placed in the same container, and everyone present can see it. Next, vegetable oil is poured into the second glass and the stick is also lowered. Everything seems to be the same as during the first stage of the experiment, except for one thing: the stick becomes invisible in oil. Children will be delighted. And in order to consolidate the result, it is necessary to pour half the water into the third glass, and then pour the same amount of oil on top. Due to the different densities of the liquids in the glass, the boundary between them will be clearly visible. And when the last stick is lowered into this container, only its middle part will remain invisible.

Experience No. 6 "Rainbow Volcano"

Inventory:

  • 7 plastic glasses of 0.5 l;
  • food coloring in all colors of the rainbow;
  • any detergent for dishes;
  • baking soda;
  • vinegar;
  • tablespoon;
  • measuring cups;
  • stirring stick.

Precautionary measures:

  1. It is necessary to cover the table with oilcloth on which the demonstration of the experiment will take place.
  2. Make sure that children in no case taste anything, and even more so do not eat or drink: all components are conditionally food, but in the concentration used they will be dangerous.

Experience progress:

7 children can demonstrate the experience at the same time. At the beginning, all plastic glasses are placed on the table in one line. Next, a small amount of food coloring of a different color is poured into each of them in the order they go in the rainbow. For the next step, 4-5 tablespoons of dish detergent are added to each of the glasses. You can not bother and pour on the eye. Now pour 1 tablespoon of soda into each container. And now it's time for a thorough mixing. You need to mix the resulting mass quickly and intensively. When this part of the work is done, we proceed to the final stage: at the same time pour 50 ml of vinegar into all cups. A reaction occurs immediately and bright and light colored foam will gush out of the cups. If the kids really like the spectacle, you can gradually pour vinegar into the container and thereby prolong this colored eruption.

Experience No. 7 "Unusual cocktail"

Inventory:

  • dishwashing liquid;
  • water;
  • vegetable oil;
  • alcohol;
  • tumbler.

Precautionary measures:

  1. This cocktail is not to be drunk.
  2. To avoid an undesirable reaction to strong odors, it is better to do the experiment in a gauze bandage.

Experience progress:

First, the glass is filled with honey to 1/6 of its volume. In the same amount, dishwashing detergent is added. After him, ordinary water is carefully added. Next is the turn of vegetable oil. This should be done slowly and in a thin stream so as not to damage the remaining layers. At the end, we pour alcohol, after which the result is shown to those present and a comment is given on how the different densities of substances help them not to mix.

Experiences can be much more. Here are only the safest and those that are suitable for any age. You can choose more complex experiments. The main thing is that absolutely all children take part in them.

Scenario move: solemn music sounds. The presenter in the suit of a scientist (white coat, glasses, hat) enters the stage.

Presenter: Hello guys! Welcome to the Science Lab, let's get to know each other! I am Professor Kolbachkina, and today we will experiment with you!

Do you like experiments?

Maybe some of you have already done some experiments?

For example, mixed porridge with soup and filled it all with Coca-Cola?

And then it turned out the most delicious experiment in the world! 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 always boils, boils, melts, smokes!

Are you ready to watch it?

Do you want to cheat yourself?

Great, but let's agree that in our laboratory we need to be careful and accurate, otherwise our experiments will not work! Deal?

Tell me, what famous scientists - chemists do you know?

Today we will see a key that can pronounce sounds, show unusual soap bubbles, cause a winter blizzard, and also watch how chemical porridge cooks by itself ... So, are you ready?

Now tell me, what time of year is it?

What season comes after autumn?

Now I suggest everyone to close their eyes and imagine that a real cold winter has come! 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 popsicles, like ice cream ...

Is it possible to make ice out of soup? You can, and you get a soup that cannot be eaten!

And now the question for the smartest: is it possible to make ice out of air? What about carbon dioxide?

We breathe in oxygen and we breathe out carbon dioxide. And yesterday I breathed, breathed and breathed 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, solid...(opens pot).

It's ice! (shows a piece of ice)

But the ice is different! It's dry ice! Do you see a light smoke coming out of it? He's melting! Only it does not turn 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 take it with gloves! Deal?

Now tell me what I have in my hands?(shows key)

Can the keys speak, sing songs? Of course not! Now let's make sure it's the other way around! So let's listen carefully...

(He leans a piece of ice against the key, the audience hears a ringing sound (beeping)).

Let's see where this sound comes from. Does the key really know how to squeak? Of course not. What kind of ice do we always have? .. Cold! And the key was warm, so what is it? .. Warm! We lean the warm key against the ice, the ice begins to melt, carbon dioxide bubbles fly out and quickly knock on the key, which is why we hear such a sound!

You will conduct the next experiment! To do this, you need to wear gloves.(Children are given gloves.)Who will read the task on the card to us, which we need to complete?(children read "Call a winter blizzard")

How can we cause a blizzard, because we don’t even have snow, and if we had it long ago it would have melted! Let's turn to science!

So, I invite here four people who want to participate in the experiment!

How to praise you? What is your first and last name?(child says his name)

So you are a scientist...(calls by name and patronymic. Other children are similarly asked and called a professor, scientist, experimenter ...)

Now we will pour hot water on a tray, take a piece of ice and throw it into the water. Ready ... Throw!(Children watch cold white smoke)

Now look, where does the smoke go up or down? Yes, it goes down, and 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 more ice? Is everything covered in snow? In fact, there will be nothing! The ice will evaporate and leave no trace behind! That's how fast it melts!

Who will read the next assignment? (Children read: "Summon Genie from the flask")

Guys, have you ever called Jin? As you know, Genie lives in a lamp. Now tell me what I have in my hands? Is it a bottle? Or a vase? Or a decanter?

No, it's a flask! Scientists need a flask to mix different liquids and conduct experiments. With the help of this flask we will conduct our experiment. Now I invite the next four participants.

Now pour hot water into the flask(pouring water). Tell me, did the water boil?

(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 hot water!

Guys, who is in favor of adding blue color? Who likes red better? Add the chosen color to the flask!(children add dye).

Now add ice cubes inside the flask(children add ice, observe a column of smoke and seething water in a flask)

And now we make wishes, and Jin, sitting in a flask, must fulfill them! To make wishes come true, you need to rub the flask, but not to the hole, and you can also listen to Jin talking in his bubbling language!

(The presenter passes through the visual rows, the children make wishes, listen to the sounds coming from the flask)

Guys, there are many more 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'll smear the edges of the container with this soap.(lubricates the edges of the container with liquid soap)

In this experiment, accuracy is needed, not a single drop of soap should get inside the container, otherwise the experiment may fail! Chemistry is 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)

And now I put the pieces of ice in the water, and very carefully so as not to splash the water, and then I stretch the soap film with the help of a washed cloth!(With the help of a soap cloth, the presenter stretches 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 up on his own? Let's figure it out. We put ice in the water, and a white smoke came out, then we ran a washed cloth over the top of the container, forming a soapy film. As a result, the film dragged on, and our smoke, escaping, began to stretch it more and more, so we saw a soap bubble that grows 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 in a wave from top to bottom).

Guys, in each of our experiments, a substance such as water is used. Do you know what is water and what is not? Let's check this out now. Prepared palms. If I call something that consists of water, you clap, for example, tea, it consists of water…. If I name something that does not consist of water, you raise your hands up. Deal? 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 a bottle.)And what is it called?(Bottle.) (Pours hot water into bottle)

So, hot water in a bottle. Now the next four members come out to me. Please introduce yourself…(Children say their names)

Add a piece of ice to the bottle and sit down.

(Children add ice to the bottle).

Check out our fizzy drink! Have you ever blown up balloons with 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, wishes will come true! So let's start!(The presenter removes the ball from the bottle, launches it, it flies, releasing smoke)

Tell me what's in my handsShows a pipe. Is that an elephant's trunk? Or a snake? Or maybe it's someone's tail? Of course it's a pipe! But she's unusual. She is musical! I invite three participants. You will be musicians. Twist this tube around.(Children twist, unusual sounds are heard).It turns out that such a pipe can also be played! In fact, when we unwind the pipe, a stream of air enters, hits the walls, which begin to oscillate, shaking the air inside, it also begins to oscillate, and this is the vibration we hear!

And now let's try to make unusual soap bubbles! They will be 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'll forgive the four participants to come to me.(Children add ice to the jar)We have poured water with soap and glycerin 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 in our palm (Blows a soap bubble into the palm, it is held in the palm of your hand)

Here are some unusual soap bubbles you can make with dry ice!

And one more experiment: tell me everyone eats porridge in the morning? Who eats semolina, raise your hands! Who loves rice porridge? Who prefers buckwheat? Herculean? Soapy? Oh, and such porridge happens? Can porridge cook on its own? Let's just like in a fairy tale about a pot of porridge ... Remember, in this fairy tale, the pot boiled porridge and boiled it so much that it flowed through the streets, between houses, and the whole city was able to eat 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 pan, but we have a pot. We will add water to it, because without it, porridge cannot be cooked! Now let's add soap grits. Add! We count all together ... One, two, three ...

(Children add a few servings of soap under the bill)

And now we take pieces of ice, at the expense of "Three" we throw ... One, two, three ...

(Children watch soapy porridge)

Now let's say "Don't boil the pot"!

No, guys, this is not a fairy tale, but science, and the pot will cook while there is a physical reaction, and until all the ice has melted!

Guys, today we conducted various experiments with you. 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)

Can I use it to inflate a soap bubble or a balloon? (Can)

And what do we see when it melts? (White smoke)

Did you enjoy the experiments? Do you want to become scientists in the future?

I want to wish you new knowledge, good grades at school, learn science! And remember, science is not only useful, but also very interesting! See you soon!
