Experiments with the egg: description. Experiments and experiments for children

To develop the baby must be from birth. For this, it is not necessary to strictly follow the instructions on psychology, to study a bunch of monotonous literature. It is enough to spend more time with the child, show him tricks, explain incomprehensible phenomena, make toys together.

Such joint activities make the child more developed and raise the authority of the adult. Become a magician and magician for your child, give him joyful moments of communication, develop interest in the surrounding reality in him and show by example the importance of the necessary regular procedures, conduct joint experiments and experiments with available products.

Boiled or raw?

Even the usual cooking in the kitchen can benefit your baby. To do this, it is enough to use those products that are always at hand. For example, do experiments with a chicken egg at home. Such activities will help to understand the intricacies and complexities of individual things and subjects, and also answer a number of complex questions.

First, teach the child to distinguish the boiled egg from raw. In appearance they are exactly the same, so at first glance it is impossible to make the right choice.

To do this, you need to untwist the eggs and see how they behave. Boiled immediately begins to spin, and the raw will practically stand still. Such experiments with the egg will explain to the child that everything depends on the internal state.

The welded egg has a dense mass, and the raw egg has a dense mass. The liquid will slow down the process, so the raw egg will not spin.

Experiments with egg and vinegar

To explain the child, why you need to brush your teeth every day, it is enough to conduct a simple experiment. Take a normal chicken egg and spread one half of the toothpaste that the baby uses. Leave the second half untouched.

In a jar pour a solution of vinegar (9%) and place in it a prepared egg. After half an hour, show the baby what happened. The half that was smeared with toothpaste will remain the same, and the second, unprotected, will become thin and change color.

Such an example will clearly show the importance and usefulness of toothpaste, which will protect the teeth and preserve their color.

Experiments and experiments are more quickly perceived and absorbed by the child, rather than reading literature. It is interesting to observe them, and the results will be remembered.

Pop up egg

The process of immersion of an ordinary chicken egg in a solution of vinegar will bring a lot of pleasant impressions to the child. First it will drown and settle on the bottom, then gradually it will begin to fill with a mass of bubbles. As a result of the reaction of the acid with calcium, which is part of the shell, carbon dioxide is formed.

These bubbles will cause the egg to rise to the surface. As soon as the bubbles run out, the egg will again sink to the bottom and begin to recruit a new portion of gases, which again pushes it up.

Bubble experiments with the egg will continue until the shell is depleted and gives up all the calcium for the reaction. The accumulation of bubbles will attract the attention of the baby, and your comments will help him to understand what is happening.

If the egg is left in the solution for longer, you can get an excellent rubber ball. After a while, the egg is soft and supple. It can be thrown on a plate and it will jump like a ball.

The child will definitely like experiments with the egg and he will ask them to repeat, and maybe he will learn to show himself.

Foci with egg

With an ordinary chicken egg you can show your child a lot of interesting things and explain the incomprehensible phenomena. For example, why is it easier to learn how to swim in salt water? If this is explained in words, it will not do anything, but it's another matter to show clearly.

Take the three cans. Place in one of them ordinary water, and in the other - salt water. Give the baby to put the egg there and look at what happens. Salt water pushes the egg to the surface, and in ordinary water it will be on the bottom. This is because the salt water will be heavier than a raw egg and can raise it.

Now take an empty jar and place the egg there. Alternately, pour in salt and plain water. The child will be interested in watching what is happening.

The egg will change its location. With an excess of salt water, it will float, and if there is a shortage, it will sink to the bottom. When the water concentration is balanced, the egg will occupy the middle position. It will be between the bottom and the surface.

If you do not disclose a secret at once, then you can hold such a demonstration in the form of a focus, forcing the egg to change position. Experiments with water and eggs are very simple and do not require special tools and financial costs. And the children are watching them with interest.

Egg in the bottle

Experience with an egg and a bottle will surprise not only the kid, but also the adult person. Cook a chicken egg, let it cool and clean it from the shell. Take any utensils with a neck, for example a bottle. The neck should not be very narrow, but narrower than the diameter of the egg. The experience will require matches.

1. Stage one. Take the egg and put it on the neck, let the child try to push it inside the vessel. This can not be done.
2. Stage two. Take the matches, light them and throw them inside the bottle. From above put on the egg egg with a sharp end, blocking the air access.
3. Stage three. Gradually, the process of sucking the egg inside the vessel will begin. This interesting experience will demonstrate the properties of air by changing the pressure inside and out.

Experience with the egg and the bottle can be done in the reverse order - try to get the egg back.

Turn the vessel upside down and start heating the bottom. Gradually, the egg in the bottle will start moving in the opposite direction.

This experiment can be carried out with a raw egg. To do this, it will be necessary to soften the shell in acetic acid.

A few tips:

• Preliminary it is possible to grease the neck of the bottle with oil;

• To soften the shell, it is necessary to keep the egg in the acid for at least 24 hours;

• Cover the neck with the egg as soon as you throw the matches;

• The neck should not be wide and too narrow (no more than ½ the diameter of the egg itself).

"Vanka-vstanka" from the egg

Their eggs can make a beautiful tumbler. A naughty egg is sure to be remembered by the baby, if allowed to take part in the making process.

Necessary materials - a candle, weights in the form of gaeyk, metal trifles and the egg itself. The cooking process will consist of several stages.

1. Getting started, you need to get rid of the liquid inside the egg. To do this, make a small hole from the sharp end and pour the contents.

2. Then rinse the egg inside and leave to dry. When it dries, throw a cooked "load" on the bottom and dip it with paraffin from the burning candle.

3. After hardening, test the egg. Check the fixing strength so that the load inside does not hang. The egg must constantly return to one position, with a load at the bottom.

4. Now it remains to decorate the egg and close the hole.

You can make a toy in the form of a face and glue a hat on top of the hole, thereby closing it. Give the child the opportunity to decorate the egg by himself. Perhaps he will suggest more interesting ways and options.

Conclusion

Spend more time with the baby. His constant questions indicate that he is trying to learn the world faster and understand all the subtleties. Help him with advice, entertaining games. Master toys together and explain things that are not clear.
