Experiences that can be spent with children
Not all experiments are suitable for children. Some of them may pose a danger to the life and health of children, especially preschool age. Nevertheless, under supervision and supervision of parents or other adults, a child can conduct any entertaining experiment - the main thing is to closely monitor compliance with the necessary safety requirements.
All scientific experiments for children are extremely useful. 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 gain valuable practical experience that can be applied in later life. In addition, some of these experiments can be shown as tricks, so that the child will be able to gain credibility among his friends and friends.
Experiments with water for children
All people in everyday life very often use water and completely do not think that it has truly magical and amazing properties. Meanwhile, with this liquid, you can conduct incredibly interesting experiments with children. For example, boys and girls at home can put the following experiments:
- "Up the napkin." Fill the plastic cup with water approximately 1/3. Stretch the napkin several times vertically, so that a long rectangle is formed. Then cut off a piece about 5 cm long, unfold it and put several points on it with colored markers. You should get a color line, on one side not reaching the edge by 5-7 cm. After that place the napkin in water, dropping it with the side on which the colored line is located. The child will be surprised, noticing that the liquid rises up and paints the entire remaining piece of napkin with bright colored strips.
- "The Water Rainbow." At the bottom of the basin, put a small mirror and fill it with water. Take the flashlight, turn it on and point the beam at the mirror. Try to catch the reflected beam of light with a sheet of white paper, and you will be surprised to find that it formed a bright multicolored rainbow.
Experiments with fire for children
With fire it is necessary to exercise special care, but with it it is possible to put incredibly interesting experiments for children. Try to spend with your offspring one of the following experiments:
- "Rocket". Take the tea bag and remove all the contents from it. From the shell, make a shape that resembles a Chinese flashlight. Light it with a match and watch how a small rocket will fly into the air!
- "Shadow play". Light a match and bring it to the wall at a distance of 10-15 cm. Shine the flashlight so as to catch the shadow, and you will see that only your hand and match will be reflected on the wall. The flame does not cast any shadow.
Experiments with salt for children
Interesting experiments for children can be carried out with bulk substances, for example, with salt. The guys will definitely like experiments such as:
- "Lava lamp". Fill the glass approximately 2/3 with water, and fill the rest with sunflower oil. For clarity of experiment, add a few drops of red food coloring. Then slowly pour 1 teaspoon of salt into this container. Watch the result - you will get a bright and beautiful substance that resembles lava.
- "Salt crystals." This and other similar experiments for children require a sufficient amount of time for their conduct. Meanwhile, the result of such experiments is worth the effort expended on them. Prepare a supersaturated saline solution - a new portion of salt in it should no longer dissolve. Then lower the wire with a loop at one end and put the container in a warm place. In a few days you will notice on the wire beautiful salt crystals.
Experiments with soda for children
No less spectacular experiments for children can be done with baking soda, for example, "Vulcan". Put on the table a small plastic bottle and mold around it a volcano of clay or sand. Pour 2 tablespoons of soda into a container, add about 50-70 ml of warm water, a few drops of red food coloring, and at the very end - a quarter of a glass of vinegar. Before your very eyes there will be a real eruption of the volcano, and the child will be delighted.
Other experiments for children with baking soda can be built 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, it is necessary to prepare a dense soda solution in which the loose substance is no longer soluble, 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.
Experiments with balloons for children
Often, experiments and experiments for children are associated with various properties of balloons, such as:
- "Look, he does not burst!". Inflate the air balloon and apply a lot of washing-up liquid to its top and bottom exactly in the middle. With a sharp movement of the hand, pierce the ball with a wooden skewer exactly in these places, and you will see that he has remained whole.
- "Fire resistance". Light the candle and put it on the table. After that, inflate the balloon and bring it close to the flame. You will see that it will quickly burst. In another bowl, pour water, tie it and hold it over the candle. After a while you will notice that the ball has become fireproof and safely withstands the flame.
Experiments with eggs for children
Some interesting experiments with children can be done using chicken eggs, for example:
- "It does not sink." Pour clear water into a glass and dip a chicken egg there. It will sink to the bottom. Then take out the object and dissolve in the liquid 4-5 tablespoons of salt, then put it back there. You will see that the egg is left on the surface of the water.
- Egg with a hairdo. Not all experiments for children are carried out very quickly, some experiments will have to be spent a few days. From the raw egg, remove the contents and fill it with cotton. Set the shell in a tube of toilet paper, pour on it seeds of alfalfa and pour them abundantly with water. Put it on the window, and after about 3 days you will notice that your hair has started to grow "hairs."
Experiments with lemon for children
Anything can be used to carry out the experiments. Special attention is also paid to interesting experiments with lemon, for example:
- "Cryptography." From the whole lemon squeeze the juice, put a brush in it and write on it any words. Let the secret message dry out. A sheet of paper will be absolutely clean, but if you hold it with an iron, all words will immediately appear!
- "Battery". Wash thoroughly and wipe the lemon. Take 2 pieces of copper wire 10 cm long each and peel their ends. Insert into the lemon an iron clip and fasten one of the wires to it, and the second stick into the citrus at a distance of 1-1.5 cm from the paper clip. 2 free ends of copper segments for a short while, attach to the contacts of the light bulb, and you will see that it will light up!
Experiments with paints for children
All kids love to draw, but even more interesting for them will be entertaining experiments with paints. Try one of the following experiments:
- "Colored drops". Take a few small disposable cups, in each of which place 2 drops of BF glue and 2 drops of acrylic paint of a certain color. Stir the ingredients thoroughly. Pour a sufficient amount of water into a basin or other capacious container. Alternately place in the water colored drops, and you will see that they are attracted to each other, forming bright multicolored spots.
- "The sea is worried once." Take an empty bottle and fill it with water halfway. Add a few drops of dye, and then pour in about ΒΌ of the volume of sunflower oil. Close the bottle and put it on its side. Swing it in different directions, and you will see that on the surface of the liquid waves that resemble a storm are formed.
