Experiments with a child at home. Fun experiments you can do at home

Entertaining chemical experiments will prepare children for studying chemistry at school. Most of the experiments carried out at home are not dangerous, educational, and effective. Some experiments are provided with a written description, which will help explain to the child the essence of the processes taking place and awaken interest in chemical science.

When conducting chemical experiments at home, the following safety rules must be observed:

Simple experiments for little ones

Chemical experiments for young children conducted in home environment, do not require any special substances.

Colored bubbles

For one such experiment you will need:

• fruit juice;
• sunflower oil;
• 2 effervescent tablets;
• decorative transparent container.

Stages of experience:

You can create bubbles with a stronger shell yourself by mixing water and dishwashing detergent in a combination of 2:1 + a little granulated sugar. If you add glycerin instead of sugar, the bubbles will reach very large sizes. Adding to soap solution food coloring will create colored glowing bubbles.

Night light

At home using simple substances you can make a night light. To do this you will need:

• tomato;
• syringe;
• sulfur heads from matches;
• hydrogen peroxide;
• bleach.

Sequencing:

1. Place sulfur in a bowl, add bleach, and leave for a while.
2. Draw the mixture into a syringe and prick the tomato from all sides.
3. To start chemical reaction hydrogen peroxide must be introduced. This is also done with a syringe in the place where the petiole was located.
4. Being in dark room, the tomato will emit soft light.

Carefully! You can no longer eat this tomato.

Sizzling balls

You can make your own sizzling balls for children's bathing.

During work, hands must be protected with gloves.

Sequencing:

Floating worms

For the next experiment you will need:

• 3 jelly worm candies without sugar sprinkles;
• soda;
• acetic acid;
• water;
• glass glasses.

Stages of work:

1. The first glass is half filled with acetic acid.
2. Pour warm water into the second glass and dilute 60 g of soda.
3. Place the candies in the solution and leave for 15 minutes.
4. Remove the candies from the soda solution and place them in a glass with the essence.
5. The surface of the candy will immediately become covered with bubbles; they will continuously rise to the surface and fall to the bottom of the glass. This happens because the soda first fills the pores of the candy, then, reacting with vinegar, it releases carbon dioxide, which raises the candy to the top.
6. When they come into contact with air, the bubbles burst, the candy sinks to the bottom and again becomes covered with bubbles and rises.

Experiments for older children

Chemical experiments for children at home can be more complex and interesting.

Volcano

So, any schoolchild can simulate a volcanic eruption at home:

Colored foam

To experience creating colored foam you will need:

Sequencing:

1. The glasses are placed on a tray, half filled with soda, and dyes are added.
2. Mix vinegar with detergent, pour into glasses.
3. Colored foam will come out of each glass. You can pour the vinegar mixture into glasses several times until all the soda is released.

Malachite egg

The experiment of dyeing a chicken egg the color of malachite is lengthy, but interesting:

1. To do this, remove the contents from the egg: make 2 holes and blow it out.
2. For weight in empty egg Place a little plasticine.
3. Dissolve a spoon in 0.5 liters of water copper sulfate(This can be purchased at a hardware store).
4. Dip the egg into the solution; the shell should be completely immersed in the solution.
5. After a few days, gas bubbles will appear.
6. After a week, the shell will acquire a light blue-green color.
7. After a month, the color of the shell will become rich malachite.

Fireworks

Making fireworks with your own hands:

1. Magnesium shavings are very finely ground.
2. Sulfur match heads are separated from the wood. You will need 2-3 boxes of matches. Crushed magnesium is mixed with sulfur powder.
3. Take a metal tube and seal one of the holes tightly with plaster.
4. Pour a mixture of magnesium and sulfur into the tube. The mixture should not occupy more than half of the tube.
5. The tube is wrapped several times with foil. A wick is inserted into the free hole.
6. Such fireworks can only be exploded in deserted places.

Coloring water blue

For coloring colorless liquids Blue colour needed:

• alcohol solution of iodine;
• hydrogen peroxide;
• vitamin C tablet;
• starch;
• glass glasses.

Performing the experiment step by step:

1. A vitamin C tablet is ground into powder and dissolved in 55 ml of warm water.
2. Pour 5 ml of the resulting solution into a glass, add 5 ml of iodine and 55 ml of heated water. The iodine should become discolored.
3. Separately mix 18 ml of hydrogen peroxide, 5 g of starch, 55 ml of water.
4. The iodine solution is poured back and forth into the starch solution several times.
5. The colorless liquid will turn dark blue. Iodine loses color when it reacts with vitamin C. Starch turns blue when mixed with iodine.

Simple experiments on the properties of metals

Chemical experiments for children at home can be carried out with metals.

For simple experiments will need:

• fire;
• pieces of various metals;
• foil;
• copper sulfate;
• ammonia;
• acid.

To experiment with copper wire, a small piece of metal is twisted into a spiral and heated strongly over a fire. Then immediately lower it into a container with ammonia. The reaction will occur instantly: the metal will begin to hiss, and the black coating formed when exposed to fire will disappear. Copper wire will shine again. It is better to do the experiment several times, then the color of the ammonia will turn blue.

For the next experiment you will need solid iodine, crushed aluminum, and warm water. Iodine is mixed with aluminum in equal parts. Water is added to the mixture. The powder begins to burn, releasing purple smoke.

Another experiment will involve:

• chrome-plated paper clip;
• galvanized steel nail;
• pure steel screw;
• acetic acid;
• 3 test tubes.

Stages of experience:

1. Metal objects are placed in test tubes, filled with acid, and left for observation. In the first days, hydrogen evolution is observed.
2. On the 4th day, the acid in test tubes with metal objects with the coating it begins to turn red. In a test tube with a steel screw, the acid becomes Orange color, a precipitate appears.
3. After 2 weeks in a test tube with a paper clip, the acid turns red, but only in upper layers. Where the paperclip is located, the acid is colorless. After removing the paper clip, you can see that it appearance not changed.
4. The acid in a test tube with a nail is colored with a smooth transition from red to pale yellow. The nail hasn't changed.
5. In the 3rd test tube, layered coloration of the liquid and sediment are also observed. The screw turned black, the upper microlayers of the metal collapsed.

Conclusion: unprotected iron is susceptible to corrosion.

For the next experiment, you need to prepare a blue solution of copper sulfate (dissolve several crystals in water, stir). Place non-rusty nails in a test tube and fill with solution. After some time, the solution will turn green and the nails will turn copper-colored. This happened because iron displaced copper from the liquid, and the displaced copper settled on metal objects.

To conduct the “Hydrogen Glove” experiment you will need:

Sequencing:

1. The saline solution and copper sulfate solution are simultaneously poured into the flask. When mixed, a sea-green liquid is obtained.
2. Make a lump of foil and place it in the hole of the flask. Immediately, hydrogen begins to rapidly evolve.
3. Put a rubber glove on the neck, it will instantly fill with gas.
4. When the glove comes into contact with fire, it ruptures and the gas ignites. The liquid in the vessel gradually acquires a dirty gray tint.

The most spectacular chemical experiments for children

Chemical experiments for children at home are very diverse, and some are very impressive.

Colored foam

To make a large amount of colored foam you need:

Bleached green

For the experiment on bleaching greenery you will need:

• brilliant green solution;
• glasses;
• bleach;
• ammonia;
• vinegar;
• hydrogen peroxide;
• pills activated carbon.

Sequencing:

1. Water is poured into 6 glasses, a drop of greenery is added to each.
2. The 1st glass is set aside for comparison, bleach is added to 2, ammonia to 3, peroxide to 4.
3. Ammonia instantly discolors the liquid.
4. Small bubbles appeared in the glass with bleach, and the solution became colorless.
5. Hydrogen peroxide will discolor the liquid gradually, over about 15 minutes.
6. Adding vinegar to the solution will make the liquid brighter.
7. After 30 min. the liquid becomes lighter.
8. Activated carbon brightens the solution.

Pharaoh snake

Conducting an experiment called “Pharaoh’s Snake” will require:

Stages of experience:

1. The sand is soaked in alcohol and formed into a cone.
2. A recess is made at the top.
3. Mix soda with sugar and pour into the well.
4. The soaked sand is set on fire.
5. The mixture will turn into black balls, soda and sugar will begin to decompose.
6. After burning the alcohol, a snake will appear, consisting of the products of burning sugar.

Pharaoh's snake made from sugar and soda:

Fire without a spark

To create a fire without a spark, you need potassium permanganate, glycerin and paper.

Sequencing:

1. Place approximately 1.5 g of potassium permanganate powder in the center of a sheet of paper, cover with the free edge of the sheet.
2. Apply 3 drops of glycerin to the paper in the place where the powder is located.
3. After 30 seconds, potassium permanganate will begin to hiss, smoke and produce black foam. The exothermic reaction will heat the paper and it will catch fire.

Fireworks

To make small fireworks at home, you need to choose a small fireproof dish with a long handle.

Sequencing:

1. On a paper sheet you need to pour a crushed tablet of activated carbon, the same amount of potassium permanganate and the same amount of iron filings.
2. Fold a piece of paper in half to combine the powders (powders should not be mixed with spoons or spatulas; they may ignite).
3. Carefully pour into a fireproof container and heat over the burner. After a few seconds. the heated mixture will begin to emit sparks.

Chemistry sets for children

Chemical experiments for children at home will help you carry out special sets of substances and tools.

Experiment kit “Vulcan”

Designed for children over 14 years old, it allows you to independently reproduce the eruption of a small volcano.

Equipment:

To conduct the experiment, you first need to make the volcano itself; sand or gypsum is suitable as a material. When the mountain has frozen, a special powder is poured into the depression and set on fire. The substance begins to burn spectacularly, throwing out sparks, and ash appears.

The advantages of such an experiment include a visual representation of flammable substances. Disadvantages: availability harmful substances, can only be used once.

Home miracle laboratory: chemical experiments for children:

All children, without exception, love mysterious, enigmatic and unusual phenomena. Most children really like to carry out interesting experiments, some of which without turning to parents or other adults for help.

Experiments you can do with children

Not all experiences are suitable for children. Some of them may pose a danger to the life and health of children, especially preschool age. However, under the control and supervision of parents or other adults, a child can conduct any interesting experiment– the main thing is to carefully monitor compliance with the necessary safety requirements.

All scientific experiments extremely useful for children. They allow young inventors to visually familiarize themselves with the properties of various substances and objects, chemical compounds and much more, understand the causes of certain phenomena and acquire valuable practical experience which can be applied in later life. In addition, some such experiments can be shown as magic tricks, thanks to which the child will be able to gain authority among his friends and acquaintances.

Experiments with water for children

All the people in everyday life very often use water and do not think at all that it has truly magical and amazing properties. Meanwhile, this liquid can be used incredibly with children. For example, boys and girls can conduct the following experiments at home:

Experiments with fire for children

Special care should be taken with fire, but it can be used to create incredibly interesting experiments for children. Try one of the following experiments with your offspring:

Experiments with salt for children

Entertaining experiments for children can also be carried out with bulk substances, for example, salt. The kids will definitely enjoy experiments such as:

Experiments with soda for children

No less spectacular experiences for children can be done with baking soda, For example, "Volcano". Place a small plastic bottle on the table and make a volcano out of clay or sand around it. Pour 2 tablespoons of soda into a container, add approximately 50-70 ml warm water, a few drops of red food coloring, and at the very end - a quarter cup of vinegar. A real volcanic eruption will happen before your eyes, and your child will be delighted.

Other experiments for children with baking soda can be based on the property of this substance to crystallize. To obtain crystals, You can use the same method as in the case of salt. To do this you need to prepare a thick soda solution, in which the bulk substance no longer dissolves, and then place a metal wire or other object there and leave it for several days in a warm place. The result will not take long to arrive.

Experiments with balloons for children

Often experiences and experiments for children are associated with various properties balloons, such as:

Experiments with eggs for children

Some interesting experiments with children can be done using chicken eggs, for example:

Experiments with lemon for children

Anything can be used to conduct experiments. Interesting experiments with lemon also deserve special attention, for example:

Experiments with paints for children

All kids love to draw, but it will be even more interesting for them to conduct entertaining experiments with paints. Try one of the following experiments:

Did you know that May 29 is Chemist's Day? Who among us in childhood did not dream of creating unique magic, amazing chemical experiments? It's time to make your dreams come true! Read on quickly and we will tell you how to have fun on Chemist Day 2017, as well as what chemical experiments for children can be easily done at home.

Home volcano

If you are not already attracted, then... Do you want to see a volcanic eruption? Try it at home! To arrange a chemical experiment “volcano” you will need soda, vinegar, food coloring, plastic cup, a glass of warm water.

Pour 2-3 tablespoons of baking soda into a plastic cup, add ¼ cup of warm water and a little food coloring, preferably red. Then add ¼ vinegar and watch the volcano “erupt”.

Rose and ammonia

A very interesting and original chemical experiment with plants can be seen in the video from YouTube:

Self-inflating balloon

Do you want to conduct safe chemical experiments for children? Then you will definitely like the balloon experiment. Prepare in advance: a plastic bottle, baking soda, balloon and vinegar.

Pour 1 teaspoon of baking soda inside the ball. Pour ½ cup of vinegar into the bottle, then put a ball on the neck of the bottle and make sure that the soda gets into the vinegar. As a result of a violent chemical reaction, which is accompanied by the active release of carbon dioxide, the balloon will begin to inflate.

Pharaoh snake

For the experiment you will need: calcium gluconate tablets, dry fuel, matches or gas-burner. Watch the algorithm of actions on YouTube video:

Colorful magic

Do you want to surprise your child? Hurry up and conduct chemical experiments with color! You will need the following available ingredients: starch, iodine, transparent container.

Mix snow-white starch and brown iodine in a container. The result is an amazing mixture of blue.

Raising a snake

The most interesting home chemical experiments can be carried out using available ingredients. To create a snake you will need: a plate, river sand, powdered sugar, ethyl alcohol, a lighter or burner, baking soda.

Place a pile of sand on a plate and soak it in alcohol. Make a depression in the top of the slide, where you carefully add powdered sugar and soda. Now we set fire to the sand slide and watch. After a couple of minutes, a dark wriggling ribbon that resembles a snake will begin to grow from the top of the slide.

How to conduct chemical experiments with an explosion, see the following video from Youtube:

More than 160 experiments that clearly demonstrate the laws of physics and chemistry were filmed, edited and posted online on the scientific and educational video channel “Simple Science”. Many of the experiments are so simple that they can be easily repeated at home - they do not require special reagents or equipment. About how to make simple chemical and physical experiments at home, not only interesting, but also safe, which experiments will captivate kids and which will be interesting to schoolchildren, Denis Mokhov, author and editor-in-chief of the scientific and educational video channel “Simple Science” told Letidor.

– How did your project begin?

– Since childhood, I have loved various experiences. For as long as I can remember, I have been collecting different ideas for experiments, in books, TV shows, so that later you can repeat them yourself. When I became a father myself (my son Mark is now 10 years old), it was always important for me to maintain my son’s curiosity and, of course, to be able to answer his questions. After all, like any child, he looks at the world completely differently than adults. And at a certain point, his favorite word became the word “why?” It is from these “why?” home experiments began. After all, telling is one thing, but showing is something completely different. We can say that my child’s curiosity was the impetus for creating the “Simple Science” project.

– How old was your son when you started practicing experiments at home?

– We have been doing experiments at home since the moment our son went to school. kindergarten, somewhere after two years. At first these were completely simple experiments with water and balance. For example, jet pack , paper flowers on the water , two forks on a match head. My son immediately liked these funny “tricks.” Moreover, like me, it is always interesting for him not so much to observe as to repeat them himself.

– You can conduct interesting experiments in the bathroom with young children: with a boat and liquid soap, paper boat and hot air balloon,
tennis ball and water jet. From birth, a child strives to learn everything new; he will definitely enjoy these spectacular and colorful experiences.

When we are dealing with schoolchildren, even first-graders, then we can go all out. At this age, children are interested in relationships, they will observe the experiment more carefully, and then look for an explanation of why it happens this way and not otherwise. Here it is possible to explain the essence of the phenomenon, the reasons for the interactions, even if not in entirely scientific terms. And when on school lessons the child will encounter similar phenomena (including in high school), the teacher’s explanations will be clear to him, because he already knows this from childhood, he has personal experience in this area.

Interesting experiments for younger students

**Package pierced with pencils**

**Egg in a Bottle**

Rubber egg

**- Denis, what do you advise parents in terms of the safety of home experiments?** - I would roughly divide the experiments into three groups: harmless, experiments that require care and experiments, and the last **-** experiments that require compliance with safety precautions. If you are demonstrating how two forks rest on the end of a toothpick, then this is the first case. If you are doing an experiment with atmospheric pressure, when a glass of water is covered with a paper sheet and then turned over, then you need to be careful not to spill water on electrical appliances **–** do the experiment over the sink. When experiments involve fire, keep a container of water just in case. And if you use any reagents or chemicals (even ordinary vinegar), then it’s better to go to Fresh air or in a well-ventilated room (for example, a balcony) and be sure to put on protective goggles on the child (you can use ski, construction or sunglasses).

**– Where can I get reagents and equipment?** **– ** At home, when conducting experiments with children under 10 years of age, it is best to use publicly available reagents and equipment. This is what each of us has in the kitchen: soda, salt, egg, forks, glasses, liquid soap. Safety is paramount in our business. Especially if your “young chemist” after successful experiments together with you, will try to repeat the experiments independently. Just don’t need to prohibit anything, all children are inquisitive, and the prohibition will act as an additional incentive! It is better to explain to the child why some experiments cannot be done without adults, that there are certain rules, somewhere you need open area To conduct the experiment, rubber gloves or goggles are required. **– Have there been any cases in your practice when an experiment turned into an emergency?** **– ** Well, nothing like that happened at home. But in the editorial office of “Simple Science”, incidents often happen. Once, while doing an experiment with acetone and chromium oxide, we slightly miscalculated the proportions, and the experiment almost got out of control.

And recently, while filming for the Science 2.0 channel, we had to do a spectacular experiment when 2000 table tennis balls fly out of a barrel and fall beautifully to the floor. So, the barrel turned out to be quite fragile and instead of a beautiful flight of balls, there was an explosion with a deafening roar. **– Where do you get ideas for experiments?** **–** We find ideas on the Internet, in popular science books, in the news about some interesting discoveries or unusual phenomena. The main criteria are **–** entertainment and simplicity. We try to choose experiments that are easy to repeat at home. True, sometimes we produce “delicacies” **–** experiments that require unusual devices and special ingredients, but this does not happen too often. Sometimes we consult with professionals from certain fields, for example, when we do experiments on superconductivity at low temperatures or in chemical experiments when rare reagents are required. Our viewers (whose number this month has exceeded 3 million) also help us in finding ideas, for which we, of course, thank them.

The experiments at home that we will talk about now are very simple, but extremely entertaining. If your child is just getting acquainted with the nature of various phenomena and processes, such experiences will look like real magic for him. But it’s no secret that it is best to present complex information to children in game form- this will help consolidate the material and leave vivid memories that will be useful in further learning.

Explosion in calm water

Discussing possible experiments at home, first of all we will talk about how to make such a mini-explosion. You will need a large vessel filled with regular tap water(for example, it could be a three-liter bottle). It is advisable for the liquid to settle in a quiet place for 1-3 days. After this, you should carefully, without touching the vessel itself, drop a few drops of ink into the very middle of the water from a height. They will spread beautifully in the water, as if in slow motion.

A balloon that inflates itself

This is another interesting experiment that can be done at home. You need to pour a teaspoon of ordinary baking soda into the ball itself. Next you need to take an empty plastic bottle and pour 4 tablespoons of vinegar into it. The ball must be pulled over its neck. As a result, the soda will pour into the vinegar, a reaction will occur with the release of carbon dioxide, and the balloon will inflate.

Volcano

Using the same baking soda and vinegar, you can create a real volcano in your home! You can even use a plastic cup as a base. Pour 2 tablespoons of soda into the “mouth”, fill it with a quarter glass of heated water and add a little food coloring. dark color. Then all that remains is to add a quarter glass of vinegar and watch the “eruption”.

"Color" magic

Experiments at home that you can demonstrate to your child also include unusual changes in their color with different substances. A striking example This is due to the reaction that occurs when iodine and starch combine. By mixing brown iodine and snow-white starch, you will get a liquid... of a bright blue hue!

Fireworks

What other experiments can you do at home? Chemistry provides a huge field for activity in this regard. For example, you can make bright fireworks right in your room (but preferably in the yard). A little potassium permanganate must be crushed into a fine powder, and then take a similar amount charcoal and grind it too. After thoroughly mixing the coal with manganese, add iron powder. This mixture is poured into a metal cap (an ordinary thimble will do) and kept in the flame of the burner. As soon as the composition heats up, a whole rain of beautiful sparks will begin to scatter around.

Soda rocket

And finally, let’s talk again about chemical experiments at home, which involve the simplest and most accessible reagents - vinegar and sodium bicarbonate. IN in this case you will need to take a plastic film cassette, fill it with baking soda, and then quickly pour in 2 teaspoons of vinegar. In the next step you close homemade rocket lid, place it on the ground upside down, stand back and watch it take off.
