Experience for children at home is a real miracle
Children were always attracted by physics. Experiences at home will help you get acquainted with the laws of nature and learn a lot of new and interesting. For this, it is not necessary to wait for the onset of school time. Such a laboratory can easily be organized at home. Even with pre-school kids, games can be organized that do not require special skills and adult training. However, do not forget about the safety of children and spend them only under the supervision of parents. Then it will be possible to avoid situations that are dangerous for the child's life.
Such elementary experiments in the kindergarten will necessarily come in the liking of the kids. After all, they can create a real cloud. To do this, pour hot water into a three-liter jar. After that, put ice cubes on the baking tray and place it on top of the jar. When the air inside rises, it will begin to cool. The vapor that is contained in it condenses, resulting in a cloud. But what about the rain? Those drops that have heated up on the ground tend to up. There they cling to each other from the cold, forming clouds. Having met together, they grow, become very heavy and fall. So it's raining.
Volcano on the table
Such an experience for children will be created by my mother - a sorceress at home. To do this, you need a "magic wand", manipulating which, you need to cast a spell, and immediately "erupt". The secret of this focus is very simple. It is enough to add to the ordinary water soda, which is extinguished with vinegar. Only soda should take a lot. To make everything look very realistic, you can mold a real volcano from a plasticine with a baby. After that, you need to make a hole in it, pour in soda and pour in gradually vinegar. After a while, the spectacle will become simply fantastic: the foam starts to splash out of the volcano. So children will get acquainted with how acid interacts with alkali, and they will visually see the neutralization reaction.
Carbonated water, cooked at home
Children's experiences need to be constantly commented. The kid should be told that we all breathe air, which contains various gases. They are very difficult to distinguish, because they do not smell, and they can not be seen. One of them is carbon dioxide. It is just part of the carbonated water. You can try to make it right at home. To do this, you need two tubes of the cocktail, which differ from each other in diameter. The narrow should fit very tightly into the wide one. Next, you need to make a hole in the stopper from the plastic bottle and insert the straw there with any end. Then you need to dilute any jam with a glass of water, and in a bottle pour a spoonful of soda and pour 100 g of vinegar. After that, very quickly, you need to insert a stopper with a tube in the bottle, and the other end of it in a glass with diluted jam. The child should explain that as a result of the interaction of soda with vinegar, carbon dioxide is released, which rises upwards and comes out in the form of bubbles. So the water becomes carbonated.
A letter with a secret
This experience for children can be done together with a game called "Find a treasure." And you can just write a message to a relative. There are two ways of making such a letter. To do this, brush the dessert in milk and write the text on a white sheet of paper. It must necessarily be allowed to dry out. In order to read it later, you need to hold the paper over the steam. The main thing is not to get burned. You can also iron it with a hot iron. Such simple experiments for children will interest both adults, help to rally the family even more. You can also write lemon juice or water dissolved in citric acid. Then to solve the message it will be necessary to dissolve a few drops of iodine in the water and a little to wet them with paper.
To create the next experience for children, it will take time and patience. After all, you have to grow real crystals. To do this, you need to prepare a very strong saline solution. It should be so concentrated that the crystals no longer dissolve. After it, you need to omit the wire, at the end of which there will be a small loop. After a while, crystals will begin to form there. You can also conduct an experiment by dropping a woolen thread in place of a wire. Then the crystals will start to grow quite differently. If the kids are really interested in this experiment, you can first make a craft from the wire, and then dip it into the solution. Such an occupation is sure to entice a child who will observe what is happening with great interest.
Importance of Experiments
Thus, it is worth noting that every experience for children is very important. They are presented as a game or entertainment, but they will bring a lot of benefit to the kids. They are able to develop erudition and increase the interest of children to study, which is one of the most important conditions for preparing for school. These lessons will be in force even for those who do not have special knowledge in chemistry and physics. To conduct such experiments, you do not even need a special chemical kit, which is quite expensive. All that is necessary for this lesson can be found at home. Do not be afraid of experiments. Experiences can be diversified and complicated. Everything depends on the desire, imagination and age of the child. But do not forget: children need to understand what they are doing. Therefore, all actions need to be commented on and explain what is happening.
