Experiments for children at home. Interesting experiments and experiments for children. Scientific chemical experiments for children

What will help to benefit with the benefit of joint leisure for children and parents?  Experiments, of course. They are not only fascinating entertainment, but are also an additional tool for knowing the world. The following are master classes on experiments for children at home.  Children aged three or more years can take an active part in the experiments.

Experiments for children 3 years old

Experience for children: walking rainbow

During this experience, the child can observe the process of absorption of fluid with a solid body.

It will be required:

• iron/burning candle/burning incandescent lamp.

Conducting process:

1. A cotton wand write a secret message on paper.
2. To manifest the inscription you need a heat source. It is most convenient to use an iron. The youngest experimenters are best limited to using incandescent lamp. After heat treatment of paper due to the oxidation reaction, the written one will acquire a brown color.

Experiments for children 6 years old

Experience for children - tornado at the bank

You can observe centrifugal power in action on the example of this simple experience for children.

It will be required:

• transparent glass jar of elongated shape with a lid;
• water;
• dishes;
• sparkles.

Conducting process:

1. Fill the jar with water by 75 percent.
2. Pour a few drops of detergent into the jar.
3. Add sparkles and dye.
4. Close the jar, spin in a spiral. As a result, the movement of the liquid in the bank will be virtually.

Experience for children - salt crystals

With a little help from relatives, this experience can be carried out since the age of six.

It will be required:

• sodium salt;
• water at room temperature and temperature 50-60 degrees;
• containers of different sizes - 3 pieces;
• spoon.

The above components can be replaced with a special set for experiments for children.

Conducting process:

1. Pour heated water into a large container.
2. Place a smaller capacity in the larger bowl in which water temperature water is located.
3. Pour salt into a smaller container, mix thoroughly, leave for 5 minutes until the crystals dissolve.
4. Repeat the actions from the third point until the salt stops dissolving in saline - the resulting liquid will be called a rich solution of salt.
5. Fill another bowl with saturated salt solution. It is important that not dissolved crystals of table salt do not fall into a new container.
6. At the bottom of the bowl with saturated saline solution, put a large crystal of salt. A few days later, the start of the growth of salt crystal will be noticeable.
7. When using special sets, the manufacture of crystals is carried out according to the instructions.

Experiments for children 7 years old

Experience for children - an egg in a bottle

It will be required:

• boiled boiled chicken egg;
• glass bottle with a wide throat;
• paper;
• matches/lighter.

Conducting process:

1. Place a small lit sheet of paper in a bottle.
2. Put the peeled egg on the neck of the bottle with a sharp end down. The egg will block the access of the oxygen necessary to ensure the combustion process. The flame will go out, the cooling air will begin to contract and the egg will suck into the bottle.

Experience for children - carbon dioxide suppository

This scientific experience for children is designed to demonstrate the effect of carbon dioxide on the combustion process.

It will be required:

• glass bowl;
• baking soda;
• vinegar;
• floating candle;
• matches/lighter.

Conducting process:

1. On the side of the bowl, put a lit candle.
2. Pour soda into the bowl, extinguish it with vinegar. As a result of the reaction, carbon dioxide will accumulate into the container.
3. The upper edge of the bowl is carefully tilt towards the candle. Carbon dioxide does not support combustion and extinguishes the flame.

Experience for children - renewal of combustion

Experience demonstrates the importance of oxygen for the combustion process.

It will be required:

• cup;
• hydrogen peroxide;
• potassium permanganate;

Conducting process:

1. Pour hydrogen peroxide into a glass.
2. Pour a little potassium permanganate into the liquid. A violent reaction will begin, accompanied by the release of oxygen.
3. Dip in a glass a smacking stick so that it does not plunge into the liquid. Due to the large concentration of oxygen, the flame will flare up with great force.

Experience for children - volcanoes

The volcanoes described below can erupt the abundant number of “lava”, so it is recommended to conduct experience either in the bathroom or on the street, or additionally use a large basin.

Volcano in a flask

It will be required:

Mini-vulcans

It will be required:

• plastic cups with a capacity of 0.2 liters;
• baking soda;
• food dyes;
• vinegar;
• spoon/wand for stirring;
• protective gloves.

Conducting process:

1. Pour 2 teaspoons of soda into glasses.
2. Add a little dye to the soda, thoroughly mix the resulting mixture.
3. Place the cups in a bath or pelvis.
4. Pour vinegar into every glass. The mini-wolves are ready.

Multi -colored volcano

It will be required:

• water;
• baking soda;
• liquid food dyes;
• small plastic cup;

Conducting process:

1. Mix soda with water in such proportions, so that the mass resembles wet sand gets.
2. Form from the soda mass of the volcano, arrange it in the form of a recess.
3. Decorating the slopes of the volcano with multi -colored dyes.
4. Put a mixture of dry soda and red dye in the ventral of the volcano.
5. Pour vinegar vulcan into the vent. As a result, the volcano will begin to erupt red lava out of itself.

For clarity, the process of performing experiments for children in a video class class is attached.

Adult experiments for children

Children like these experiments, but unsafe substances are used during the experiments. Recommended for older children under the guidance of adults or adults themselves.

Experience for children - bleaching green

It will be required:

• glass glass;

• protective gloves.

Conducting process:

1. Pour water into a glass.
2. Give the water intense green with green.
3. Pour a little hydrogen peroxide into the solution.
4. Add the alkali. As a result of a chemical reaction, the solution will be discolored. Knowing the principle of neutralization of diamond green can be useful in everyday life.

Experience for children - colored metamorphoses

Experience demonstrates the influence of the hydrogen indicator of the medium on the color of the liquid.

It will be required:

2. Add a little hydrochloric acid to the first glass. The liquid will acquire a rich red color.
3. Pour a little vinegar into the second glass. The color of the solution will also become more intense, but in terms of brightness it will be inferior to the first cup.
4. Leave the third cup for comparison with untouched.
5. Add a little soda to the fourth glass. The contents of the container will acquire a lilac-gray color.
6. Pour ammonia into the fifth cup. After that, the liquid will change its color to khaki.
7. The contents of the sixth cup, after adding a small amount of solution for cleaning the pipes, will acquire a brown color.

2. Bring the water in a separate container to a saturated pink color by pouring part of the potassium permanganate solution.
3. In a separate glass in a small amount of water, dissolve half a teaspoon of sugar.
4. Pour into the sugar solution alkali.
5. Add water-sakhar-base solution to a solution of potassium permanganate and observe the reaction. First, the liquid will turn blue, then it will green, and then it will turn yellow.

Conclusion

Experiments and experiments for children are good in that they perform several functions at once: entertaining and educational.

Chemical experiments for children can be unsafe, so in no case should be neglected by protecting the eyes, skin, clothing. The complexity of the assigned tasks should correspond to the age of the child.
