For the development of a child, it is necessary to use all possible means, including experiments for children, which trained parents can conduct at home. This type of activity is very interesting for preschoolers, it helps them learn a lot about the world around them and take direct part in the research process. The main rule that mothers and fathers should adhere to is the absence of coercion: classes should be conducted only when the child himself is ready for experiments.

Physical

Such scientific experiments will interest an inquisitive little one and help him gain new knowledge:

In addition, under clear parental guidance, he will be able to repeat everything without difficulty.

Bottle filling

You should prepare your inventory in advance. Need hot water Glass bottle and a bowl of cold water(for clarity, the liquid should be pre-tinted).

The procedure is as follows:

  1. It is necessary to pour hot water into the bottle several times so that the container warms up properly.
  2. Pour out the hot liquid completely.
  3. Turn the bottle upside down and place it in a bowl of cold water.
  4. You will see that water from the bowl will begin to flow into the bottle.

Why is this happening? The hot liquid filled the bottle warm air. As the gas cools, it contracts, causing the volume it occupies to decrease, forming a low-pressure environment in the bottle. As water flows in, it restores balance. This experiment with water can be done at home without any problems.

With a glass

Every child, even at 3-4 years old, knows that if you turn over a glass filled with water, the liquid will spill out. However, there is an interesting experience that can prove the opposite.

Procedure:

  1. Pour water into a glass.
  2. Cover it with a piece of cardboard.
  3. Holding the sheet with your hand, carefully turn the structure over.
  4. You can remove your hand.

Surprisingly, the water will not spill out - the molecules of the cardboard and the liquid will mix at the moment of contact. Therefore, the sheet will hold on, becoming a kind of lid. You can also tell the child about atmospheric pressure, that it exists both inside the glass and outside, while in the container it is lower, outside it is higher. Due to this difference, water does not spill out.

A similar experiment is best carried out over a basin, since gradually the paper material will get wet and the liquid will drip.

Developmental experiments

There are a lot of really interesting experiments for kids.

Eruption

This experience is rightfully considered one of the most exciting and therefore loved by children. To carry it out you will need:

  • soda;
  • red paint;
  • citric acid or lemon juice;
  • water;
  • a little detergent.

First you should build the “volcano” itself, making a cone from thick paper, securing the edges with tape and cutting a hole on top. Then the resulting blank is put on any bottle. To resemble a volcano, it should be covered with brown plasticine and placed on a large baking sheet so that the “lava” does not spoil the surface of the table.

Procedure:

  1. Pour soda into the bottle.
  2. Add paint.
  3. Add a drop of detergent (1 drop).
  4. Pour water and mix well.

For the “eruption” to begin, you need to ask the child to add a little citric acid(or lemon juice). This simplest example chemical reaction.

Dancing worms

This simple, fun experiment can be done with both preschoolers and elementary school students. Necessary equipment:

  • corn starch;
  • water;
  • baking tray;
  • paints (food coloring);
  • music column.

First you need to mix 2 cups of starch and a glass of water. Pour the resulting substance onto a baking sheet, add paint or dye.

All that remains is to turn on loud music and place the baking sheet on the speaker. The colors on the workpiece will be mixed in a chaotic manner, creating a beautiful, unusual spectacle.

We use food

To make an experiment that is unusual, interesting for your child and educational, it is not at all necessary to purchase complex equipment and expensive materials. We invite you to get to know the very simple options, available for execution at home.

With egg

Necessary equipment:

  • glass of water (tall);
  • egg;
  • salt;
  • water.

The idea is simple - an egg immersed in water will sink to the bottom. If you add it to liquid table salt(about 6 tbsp), then it will rise to the surface. This physical experience with salt helps illustrate the concept of density to your child. So, salted water has more water, so the egg can float on the surface.

You can also show reverse action(this is why it was recommended to take a tall glass) - when adding to salted liquid, a simple tap water the density will decrease and the egg will sink to the bottom.

Invisible ink

A very interesting and simple trick, which at first will seem like real magic to the baby, and after the parents explain it, it will help to learn about oxidation.

Necessary equipment:

  • ½ lemon;
  • water;
  • spoon and plate;
  • paper;
  • lamp;
  • cotton swab.

If lemon is not available, you can use analogues, such as milk, onion juice or wine.

Procedure:

  1. Squeeze the citrus juice, add it to a plate, mix with an equal amount of water.
  2. Dip the tampon into the resulting liquid.
  3. Use it to write something that your child can understand (or draw).
  4. Wait until the juice dries, becoming completely invisible.
  5. Heat the sheet (using a lamp or holding it over a fire).

Text or a simple drawing will become visible due to the fact that the juice has oxidized and turned brown when the temperature rises.

Color explosion

The little ones can enjoy a fun experiment with milk and paints, which can be carried out without any problems in the kitchen.

Required products and equipment:

  • milk (preferably high fat content);
  • food coloring (several colors - the more, the more interesting and brighter it will be);
  • dishwashing liquid;
  • plate;
  • cotton buds;
  • pipette.

If dishwashing liquid is not available, it is acceptable to use liquid soap.

Procedure:

  1. Pour milk into a plate. It should completely hide the bottom.
  2. Let the liquid sit for a while until it reaches room temperature.
  3. Using a pipette, carefully drop several different food colors into the bowl of milk.
  4. By lightly touching the liquid with a cotton swab, you need to show the baby what is happening.
  5. Next, take a second stick and dip it in detergent. It touches the surface of the milk and holds for 10 seconds. There is no need to mix colorful stains, a gentle touch is enough.

Next, the baby will be able to observe the most beautiful thing - the colors begin to “dance”, as if trying to escape from the soap stick. Even if you remove it now, the “explosion” will continue. At this stage, you can invite the child to participate himself - add dye, immerse a soapy stick in the liquid.

The secret of the experience is simple - detergent destroys the fat contained in milk, which causes the “dance”.

With sugar

For children 3-4 years old, various experiments with food will be very interesting. The child will be happy to learn about new qualities of his usual food.

For this entertaining activity you will need:

  • 10 tbsp. l. Sahara;
  • water;
  • food colors of several colors;
  • two spoons (teaspoon, tablespoon);
  • syringe;
  • 5 glasses.

First you need to add sugar to the glasses according to this scheme:

  • in the first glass - 1 tbsp. l.;
  • in the second - 2 tbsp. l.;
  • in the third - 3 tbsp. l.;
  • in the fourth - 4 tbsp. l.

Add 3 tsp to each of them. water. Mix. Then you need to add a dye of your own color to each of the glasses and mix again. The next step is to carefully take the colored liquid from the fourth glass using a syringe or a teaspoon and pour it into the fifth, which was empty. Then colored water is added in the same order from the third, second and finally from the first glasses.

If you act carefully, the colored liquids will not mix, but, when layered on top of each other, they will help create a bright, unusual pyramid. The secret of the trick is that the density of water changes depending on the amount of sugar added to it.

With flour

Let's consider another interesting experience for children, simple and safe. It can be carried out either in kindergarten, and at home.

Necessary equipment:

  • flour;
  • salt;
  • paints (gouache);
  • brush;
  • sheet of cardboard.

Procedure:

  1. In a small glass you need to mix 1 tbsp. l. flour and salt. This is a blank from which we will later make paint of the same color. Accordingly, the number of such blanks is equal to the number of flowers.
  2. Add 3 tbsp to each glass. l. water and gouache.
  3. Using paint, ask your child to draw a picture on cardboard using a brush or cotton swab, one for each color.
  4. Place the finished creation in the microwave (power 600 W) for 5 minutes.

The paints, which are dough, will rise and harden, making the drawing three-dimensional.

Lava lamp

Another unusual children's experiment allows you to create a real lava lamp. After watching just once, even a novice researcher will be able to repeat the experiment with his own hands, without the help of adults.

Required equipment and materials:

  • vegetable oil(cup);
  • salt (1 tsp);
  • water;
  • food coloring (several shades);
  • glass jar.

Procedure:

  1. Fill the jar 2/3 full with water.
  2. Add vegetable oil, which at this stage forms a thick film on the surface.
  3. Add food coloring.
  4. Slowly add salt.

Under the weight of the salt, the oil will begin to sink to the bottom, and the dye will make the spectacle more colorful and impressive.

With soda

An experiment with soda is perfect for demonstrating to a preschool child:

  1. Pour the drink into a glass.
  2. Drop a few peas or cherry pits into it.
  3. Watch how they gradually rise from the bottom and fall again.

An amazing sight for a child who does not yet know that the peas are surrounded by bubbles of carbon dioxide, which brings them to the surface. Submarines operate on a similar principle.

With water

There are several educational optical experiments that, despite their simplicity, are very interesting.

  • The missing ruble

Water is poured into a jar and an iron ruble is dropped into it. Now you need to ask the baby to find the coin by looking through the glass. Due to the optical phenomenon of refraction, the eye will not be able to see the ruble if it is directed from the side. If you look into the jar from above, the coin will be in place.

  • curved spoon

Let's continue exploring optics with a preschooler. This easy but visual experiment is carried out like this: you need to pour water into a glass and dip a spoon into it. Ask your baby to look from the side. He will see that at the boundary of the media - water and air - the spoon appears curved. By taking out the spoon, you can make sure that everything is okay with it.

The child should be explained that a ray of light bends when passing through water, which is why we see a changed image. You can continue the water theme and lower the same spoon into a small jar. Curvature will not occur since the walls of this container are smooth.

This biological experiment will help your child get acquainted with the world of living nature and observe how a sprout is formed. Beans or peas are needed for this.

Parents can invite the young botanist to independently moisten a piece of gauze folded several times with water, place it on a saucer, place peas or beans on the cloth and cover with damp gauze. The baby’s task is to carefully ensure that the seeds are moistened at all times and check them regularly. In a couple of days the first shoots will appear.

Photosynthesis process

This plant and candle activity is best suited for younger students who know that trees and grass absorb carbon dioxide and release oxygen.

The gist is this:

  1. Carefully place burning candles into two jars.
  2. Place a living plant in one of them.
  3. Cover both containers with a lid.

Observe that the candle in the jar with the plant continues to burn because oxygen is present in it. In the second bank it goes out almost immediately.

Entertaining

We catch electricity. This one is small and safe experience It can easily be done with kids.

  1. One inflated balloon is placed on the wall, several others lie on the floor.
  2. The mother invites the child to place all the balls on the wall. However, they will not hold on and will fall.
  3. The mother asks the baby to rub the ball on his hair and try again. Now the ball has been attached.

After this, you need to tell that the “miracle” happened thanks to the electricity that was generated when the ball was rubbed on the hair.

Another option for the curious is an experiment with foil. It goes like this:

  1. A small piece of foil needs to be cut into strips.
  2. Ask your little one to comb her hair.
  3. Now you need to lean the comb against the strip and observe. The foil will stick to the comb.

You can also demonstrate “The Lost Chalk” to children. To do this, a piece of ordinary chalk is placed in vinegar. The limestone will begin to hiss and decrease in size. After some time it will completely dissolve. This is due to the fact that chalk, when in contact with vinegar, turns into other substances.

Experiments with preschool children - a great opportunity develop their curiosity, answer many questions in a visual and understandable form. In addition, by offering children a variety of experiments, attentive parents will help them outline their own range of interests at an early age. And doing the research itself will be a great and fun pastime.

August 2nd, 2015

Children are always trying to learn something new every day and they always have a lot of questions. They can explain certain phenomena, or they can clearly show how this or that thing, this or that phenomenon works. In these experiments, children will not only learn something new, but also learn how to create various crafts, which they can then play with.

1. Experiments for children: lemon volcano

You will need:

2 lemons (for 1 volcano)

Baking soda

Food coloring or watercolor paints

Dishwashing liquid

Wooden stick or spoon (if desired)

1. Cut off the bottom of the lemon so it can be placed on flat surface.

2. On the back side, cut out a piece of lemon as shown in the image.

* You can cut off half a lemon and make an open volcano.

3. Take the second lemon, cut it in half and squeeze the juice into a cup. This will be the reserved lemon juice.

4. Place the first lemon (with the cut out part) on the tray and use a spoon to “squeeze” the lemon inside to squeeze out some of the juice. It is important that the juice is inside the lemon.

5. Add food coloring or watercolor inside the lemon, but do not stir.

6. Pour dish soap inside the lemon.

7. Add a spoonful to the lemon baking soda. The reaction will begin. You can use a stick or spoon to stir everything inside the lemon - the volcano will begin to foam.

8. To make the reaction last longer, you can gradually add more soda, dyes, soap and reserve lemon juice.

2. Home experiments for children: electric eels made from chewing worms

You will need:

2 glasses

Small capacity

4-6 gummy worms

3 tablespoons baking soda

1/2 spoon of vinegar

1 cup water

Scissors, kitchen or stationery knife.

1. Using scissors or a knife, cut lengthwise (precisely lengthwise - it won't be easy, but be patient) each worm into 4 (or more) pieces.

* How smaller piece, all the better.

*If the scissors do not cut properly, try washing them with soap and water.

2. Mix water and baking soda in a glass.

3. Add pieces of worms to the solution of water and soda and stir.

4. Leave the worms in the solution for 10-15 minutes.

5. Using a fork, transfer the worm pieces to a small plate.

6. Pour half a spoon of vinegar into an empty glass and start putting worms into it one by one.

* The experiment can be repeated if you wash the worms plain water. After a few attempts, your worms will begin to dissolve, and then you will have to cut a new batch.

3. Experiments and experiments: a rainbow on paper or how light is reflected on a flat surface

You will need:

Bowl of water

Clear nail polish

Small pieces of black paper.

1. Add 1-2 drops of clear nail polish to a bowl of water. Watch how the varnish spreads through the water.

2. Quickly (after 10 seconds) dip a piece of black paper into the bowl. Take it out and let it dry on a paper towel.

3. After the paper has dried (this happens quickly) start turning the paper and look at the rainbow that appears on it.

* To better see a rainbow on paper, look at it under the sun's rays.

4. Experiments at home: rain cloud in a jar

As small drops of water accumulate in a cloud, they become heavier and heavier. Eventually they will reach such a weight that they can no longer remain in the air and will begin to fall to the ground - this is how rain appears.

This phenomenon can be shown to children using simple materials.

You will need:

Shaving foam

Food coloring.

1. Fill the jar with water.

2. Apply shaving foam on top - it will be a cloud.

3. Have your child start dripping food coloring onto the “cloud” until it starts to “rain” - drops of coloring begin to fall to the bottom of the jar.

During the experiment, explain this phenomenon to your child.

You will need:

Warm water

Sunflower oil

4 food colors

1. Fill the jar 3/4 full with warm water.

2. Take a bowl and stir 3-4 tablespoons of oil and a few drops of food coloring into it. IN in this example 1 drop of each of 4 dyes was used - red, yellow, blue and green.

3. Using a fork, stir the coloring and oil.

4. Carefully pour the mixture into a jar of warm water.

5. Watch what happens - the food coloring will begin to slowly fall through the oil into the water, after which each drop will begin to disperse and mix with the other drops.

* Food coloring dissolves in water, but not in oil, because... The density of oil is less than water (that’s why it “floats” on water). The dye droplet is heavier than the oil, so it will begin to sink until it reaches the water, where it will begin to disperse and look like a small fireworks display.

6. Interesting experiments: ina circle in which the colors merge


You will need:

- printout of the wheel (or you can cut out your own wheel and draw all the colors of the rainbow on it)

Elastic band or thick thread

Glue stick

Scissors

Skewer or screwdriver (to make holes in the paper wheel).

1. Select and print the two templates you want to use.

2. Take a piece of cardboard and use a glue stick to glue one template to the cardboard.

3. Cut out the glued circle from cardboard.

4. TO back side Glue the second template onto the cardboard circle.

5. Use a skewer or screwdriver to make two holes in the circle.

6. Thread the thread through the holes and tie the ends into a knot.

Now you can spin your top and watch how the colors merge on the circles.

7. Experiments for children at home: jellyfish in a jar

You will need:

Small transparent plastic bag

Transparent plastic bottle

Food coloring

Scissors.

1. Place the plastic bag on a flat surface and smooth it out.

2. Cut off the bottom and handles of the bag.

3. Cut the bag lengthwise on the right and left so that you have two sheets of polyethylene. You will need one sheet.

4. Find the center of the plastic sheet and fold it like a ball to make a jellyfish head. Tie a thread in the area of ​​the jellyfish's "neck", but not too tightly - you need to leave a small hole through which to pour water into the jellyfish's head.

5. There is a head, now let's move on to the tentacles. Make cuts in the sheet - from the bottom to the head. You need approximately 8-10 tentacles.

6. Cut each tentacle into 3-4 smaller pieces.

7. Pour some water into the jellyfish's head, leaving room for air so the jellyfish can "float" in the bottle.

8. Fill a bottle with water and put your jellyfish in it.

9. Add a couple drops of blue or green food coloring.

* Close the lid tightly to prevent water from spilling out.

* Let the children turn the bottle over and watch the jellyfish swim in it.

8. Chemical experiments: magic crystals in a glass

You will need:

Glass glass or bowl

Plastic bowl

1 cup Epsom salts (magnesium sulfate) - used in bath salts

1 cup hot water

Food coloring.

1. Place Epsom salts in a bowl and add hot water. You can add a couple of drops of food coloring to the bowl.

2. Stir the contents of the bowl for 1-2 minutes. Most of the salt granules should dissolve.

3. Pour the solution into a glass or glass and place it in the freezer for 10-15 minutes. Don't worry, the solution is not so hot that the glass will crack.

4. After freezing, transfer the solution to the main compartment of the refrigerator, preferably on the top shelf, and leave overnight.

The growth of crystals will be noticeable only after a few hours, but it is better to wait overnight.

This is what the crystals look like the next day. Remember that crystals are very fragile. If you touch them, they will most likely immediately break or crumble.

Good afternoon, guests of the Eureka Research Institute website! Do you agree that knowledge supported by practice is much more effective than theory? Entertaining experiments in physics will not only provide great entertainment, but will also arouse a child’s interest in science, and will also remain in memory much longer than a paragraph in a textbook.

What can experiments teach children?

We bring to your attention 7 experiments with explanations that will definitely raise the question in your child “Why?” As a result, the child learns that:

  • By mixing 3 primary colors: red, yellow and blue, you can get additional ones: green, orange and purple. Have you thought about paints? We offer you another one, unusual way make sure of this.
  • Light reflects off a white surface and turns into heat if it hits a black object. What could this lead to? Let's figure it out.
  • All objects are subject to gravity, that is, they tend to a state of rest. In practice it looks fantastic.
  • Objects have a center of mass. And what? Let's learn to benefit from this.
  • Magnet is an invisible but powerful force of some metals that can give you the abilities of a magician.
  • Static electricity can not only attract your hair, but also sort out small particles.

So let's make our kids proficient!

1. Create a new color

This experiment will be useful for preschoolers and primary schoolchildren. To conduct the experiment we will need:

  • flashlight;
  • red, blue and yellow cellophane;
  • ribbon;
  • white wall.

We conduct the experiment near a white wall:

  • We take a lantern, cover it first with red and then yellow cellophane, and then turn on the light. We look at the wall and see an orange reflection.
  • Now we remove the yellow cellophane and put a blue bag on top of the red one. Our wall is illuminated in purple.
  • And if we cover the lantern with blue and then yellow cellophane, then we will see a green spot on the wall.
  • This experiment can be continued with other colors.
2. Black color and Sunbeam: explosive combination

To carry out the experiment you will need:

  • 1 transparent and 1 black balloon;
  • magnifying glass;
  • Sun Ray.

This experience will require skill, but you can do it.

  • First you need to inflate a transparent balloon. Hold it tightly, but do not tie the end.
  • Now, using the blunt end of a pencil, push the black balloon halfway inside the transparent one.
  • Inflate the black balloon inside the clear one until it fills about half the volume.
  • Tie the end of the black ball and push it into the middle of the clear ball.
  • Inflate the transparent balloon a little more and tie the end.
  • Position the magnifying glass so that the sun's ray hits the black ball.
  • After a few minutes, the black ball will burst inside the transparent one.

Tell your baby what transparent materials miss sunlight, so we see the street through the window. A black surface, on the contrary, absorbs light rays and turns them into heat. This is why it is recommended to wear light-colored clothing in hot weather to avoid overheating. When the black ball heated up, it began to lose its elasticity and burst under the pressure of the internal air.

3. Lazy ball

The next experiment is a real show, but you will need to practice to carry it out. The school gives an explanation for this phenomenon in the 7th grade, but in practice this can be done even in preschool age. Prepare the following items:

  • plastic cup;
  • metal dish;
  • cardboard sleeve from under toilet paper;
  • tennis ball;
  • meter;
  • broom.

How to conduct this experiment?

  • So, place the glass on the edge of the table.
  • Place a dish on the glass so that its edge on one side is above the floor.
  • Place the base of the toilet paper roll in the center of the dish directly above the glass.
  • Place the ball on top.
  • Stand half a meter from the structure with a broom in your hand so that its rods are bent towards your feet. Stand on top of them.
  • Now pull back the broom and release it sharply.
  • The handle will hit the dish, and it, together with the cardboard sleeve, will fly to the side, and the ball will fall into the glass.

Why didn't it fly away with the rest of the items?

Because, according to the law of inertia, an object that is not acted upon by other forces tends to remain at rest. In our case, the ball was only affected by the force of gravity towards the Earth, which is why it fell down.

4. Raw or cooked?

Let's introduce the child to the center of mass. To do this, let's take:

· cooled hard-boiled egg;

· 2 raw eggs;

Invite a group of children to distinguish a boiled egg from a raw one. However, you cannot break eggs. Say that you can do it without fail.

  1. Roll both eggs on the table.
  2. An egg that spins faster and with uniform speed, - boiled.
  3. To prove your point, crack another egg into a bowl.
  4. Take a second raw egg and a paper napkin.
  5. Ask a member of the audience to make the egg stand on the blunt end. No one can do this except you, since only you know the secret.
  6. Just vigorously shake the egg up and down for half a minute, then easily place it on a napkin.

Why do eggs behave differently?

They, like any other object, have a center of mass. That is, different parts of an object may not weigh the same, but there is a point that divides its mass into equal parts. U boiled egg due to a more uniform density, the center of mass during rotation remains in the same place, and raw egg it moves along with the yolk, making it difficult to move. In a raw egg that has been shaken, the yolk drops to the blunt end and the center of mass is there, so it can be placed.

5. “Golden” mean

Invite the children to find the middle of the stick without a ruler, but just by eye. Evaluate the result using a ruler and say that it is not entirely correct. Now do it yourself. A mop handle is best.

  • Raise the stick to waist level.
  • Lay her down on 2 index fingers, keeping them at a distance of 60 cm.
  • Move your fingers closer together and make sure the stick doesn't lose its balance.
  • When your fingers come together and the stick is parallel to the floor, you have reached your goal.
  • Place the stick on the table, keeping your finger on the desired mark. Use a ruler to make sure you have completed the task accurately.

Tell your child that you found not just the middle of the stick, but its center of mass. If the object is symmetrical, then it will coincide with its middle.

6. Zero gravity in a jar

Let's make the needles hang in the air. To do this, let's take:

  • 2 threads of 30 cm;
  • 2 needles;
  • transparent tape;
  • liter jar and lid;
  • ruler;
  • small magnet.

How to conduct the experiment?

  • Thread the needles and tie the ends with two knots.
  • Tape the knots to the bottom of the jar, leaving about 1 inch (2.5 cm) to the edge.
  • From the inside of the lid, glue the tape in the form of a loop, with the sticky side facing out.
  • Place the lid on the table and glue a magnet to the hinge. Turn the jar over and screw on the lid. The needles will hang down and be drawn towards the magnet.
  • When you turn the jar upside down, the needles will still be drawn to the magnet. You may need to lengthen the threads if the magnet does not hold the needles upright.
  • Now unscrew the lid and place it on the table. You are ready to perform the experiment in front of an audience. As soon as you screw on the lid, the needles from the bottom of the jar will shoot up.

Tell your child that a magnet attracts iron, cobalt and nickel, so iron needles are susceptible to its influence.

7. “+” and “-”: beneficial attraction

Your child has probably noticed how hair is magnetic to certain fabrics or combs. And you told him that static electricity is to blame. Let's do an experiment from the same series and show what else the “friendship” of negative and negative people can lead to. positive charges. We will need:

  • paper towel;
  • 1 tsp. salt and 1 tsp. pepper;
  • spoon;
  • balloon;
  • woolen item.

Experiment stages:

  • Place a paper towel on the floor and sprinkle the salt and pepper mixture on it.
  • Ask your child: how to separate salt from pepper now?
  • Rub the inflated balloon on a woolen item.
  • Season it with salt and pepper.
  • The salt will remain in place, and the pepper will be magnetized to the ball.

After rubbing against the wool, the ball acquires a negative charge, which attracts positive ions from the pepper. The salt's electrons are not so mobile, so they do not react to the approach of the ball.

Experiences at home are valuable life experiences

Admit it, you yourself were interested in watching what was happening, and even more so for the child. Performing amazing tricks with the most simple substances, you will teach your baby:

  • trust you;
  • see the amazing in everyday life;
  • It’s exciting to learn the laws of the world around you;
  • develop diversified;
  • learn with interest and desire.

We remind you once again that developing a child is simple and you don’t need a lot of money and time. See you soon!

Children are great whys. By their very nature, they are aimed at understanding the world, and until a certain age, the world is ready to give them discoveries almost every day. Children are ready for the most risky experiments in order to answer the questions “How?”, “Why?”, “What will happen?” We, parents, out of fear for their safety and the safety of the objects surrounding our children, try to limit the flight of their imagination, especially if we're talking about about preschoolers and 7-8 years old.

Preserving this curiosity and inquisitiveness is very important; it is this trait that will bring the child both deep knowledge and the ability to implement it. Entertaining experiments will force the child to consciously read physics or chemistry textbooks, in an effort to understand and explain the results of the experiment.

Therefore, responsible parents strive to support children in their desire to discover chemical, physical, biological and other laws themselves. Having caught the demand, stores offer to buy various children's kits to conduct experiments and experiments for children 7-8 years old at home.

You can buy these kits, but children can easily conduct many fun and interesting scientific experiments with their parents themselves, creating the necessary kits from improvised materials at home. At home you can do experiments in chemistry, physics, biology. You can do at least 10 experiments with Coca-Cola alone. The main thing is to teach little researchers safety rules.

Most of the experiences and experiments for children that parents can read about and offer to kids for practice are completely safe. But many children at 8, and even more so 10 years old, are already quite free to find videos on the Internet where slightly older children demonstrate their experiments, and not all of them, even with Coca-Cola, are safe for a beginner.

Or maybe your young researcher will decide to conduct chemical experiment own development. Therefore, rule number one, which, first of all, needs to be taught to children is to always coordinate upcoming scientific experiments with an adult.

  • Before doing this, carefully read the instructions for the experiment. All sets sold are supplied with them.
  • The place for experiments must be carefully chosen and well prepared. Remove all unnecessary items, especially flammable materials and fragile items. There should be enough light, nearby water, and the possibility of ventilation.
  • Be careful when handling fire, hot or sharp objects.
  • Use separate dishes for experiments. After use, wash and put it away thoroughly.
  • Do not put anything in your mouth, taste it or play with the products used or received.
  • If your hands get dirty, wash them immediately so as not to rub your face and eyes with dirty hands.
  • Do not lean close to the experiment site to avoid splashes, sparks, etc. do not come into contact with skin or eyes.
  • At the end of the experiment, we carefully clean everything, wash our hands, and if necessary, ventilate the room.
  • Carefully pour used liquids into the sink, turning on cold water so that she dilutes it.

But still simple experiments with fire or chemicals, even something as common at home as vinegar, children should only do it under the supervision of an adult.

Experiments for children! Experiment for children No. 1 – Rainbow water

Boat on a soap engine

You don't have to buy complicated kits for this experience. Enough water, liquid soap and plastic corner. Using scissors, cut out a triangular boat with a slot from a corner or film and round hole in the middle. This is quite feasible for children 7-8 years old. Then we lower the resulting boat into a vessel with water and drop liquid soap into the hole. The ship begins to move quickly through the water. And so on after every drop of soap.

Soda experience

This simple and fun activity will help engage children's attention to physics concepts such as density, volume and weight. You don’t need special kits for it; just buy several metal cans of soda of the same size. For example, buy Sprite, Coca-Cola, Pepsi and Fanta, and ask your child the question: “What will happen to them if you put them in water? Will they drown or not?

You can even bet on how the next jar will behave. Then carefully lower the jars into a container of water and observe. Some jars sink to the bottom, while others float in it. Although a child of 7 or even 10 years old does not yet learn physics or chemistry, this visual experience will help to remember that objects with the same volume can have different weights and different densities.

Paper cover

This scientific experience looks like a magic trick. Take a glass of water, pour water into it, press a piece of thick paper on top and carefully turn the glass over. The water doesn't spill out! The paper remains pressed to the glass, as if glued. The explanation for the secret of this experiment is that air presses on the paper.

Homemade rainbow using water and mirror

You can delight your children by making them feel like a wizard by creating your own rainbow. To do this, the child immerses a small mirror in water and shines a flashlight on it. On White list paper we catch the reflection and there it is - a rainbow!

Rene Descartes' experiment or pipette diver

It is believed that this interesting experiment was first made by the 16th century physicist and mechanic from France, Rene Descartes. We will not repeat his experience exactly, because today there are plastic bottles. In one of them we fill water almost to the very edges and lower the pipette there. We first fill the pipette with a little water, so that when immersed in the bottle it floats, with its upper rubber end slightly protruding from the water.

Close the bottle and squeeze it. The pipette goes to the bottom. Let go of the sides of the bottle and the pipette floats up. When you squeeze the bottle, the pressure of the water in it increases, and it penetrates into the pipette. It becomes heavier and goes to the bottom. The pressure weakens and the air pushes out the water, the pipette becomes lighter again and floats up.

From glass to glass

This experiment can be done even by a 5-year-old child. One glass is filled with water and a strip of fabric is immersed in it, the second edge of which is lowered into the empty glass. It is placed slightly lower than full, and gradually the water flows through the fabric from full to empty.

Coca-Cola experience

The Internet is full of videos where guys have the most different experiences with Coca-Cola. You can find 10 or 20 such experiments. Add sugar, Mentos candies, soda or salt, milk and dry ice to Coca-Cola and look at the result. With a child of 8–10 years old, it is quite possible to create a volcano out of Coca-Cola.

To do this, a tall glass or a small plastic bottle insert it into a dark paper cone that will represent a volcano. We put the volcano in the basin. Fill the vessel halfway with Coca-Cola and throw in the Mentos candies. Then we admire the volcanic eruption from a fountain of foam. The fountain from our volcano will be even higher if we add soda to Coca-Cola instead of candy.
