Small children, more than anyone else, are ready to absorb new knowledge. However, you need to choose such a way to feed them so that it is interesting to the kids. Water experiments are ideal for playing with children. However, experiments need to be selected such that the child does not just be happy with the resulting focus, but also understood his meaning. The Club offers several common experiments with water for preschool children.
You can start with a simple experiment for children 3-4 years old, which generally knows about the world around. For experience, you will need different items where you can pour water: a glass, a vase, a bucket, and the surface of the table is suitable. Capacities should be transparent so that the child see the water well in them.
In order for the children to find out about another one of the properties of water, you need to take a bottle of 1.5-2 liters, color isolate and water itself, of course. The experiment is better to spend in winter, with a significant decrease in temperature or with a large freezer, where the bottle can be put up vertically.
Algorithm for carrying out water experience:
The experiment allows the baby to independently make sure that the ice was formed much higher than the level of the glued tape. So he will understand that during freezing the water expands.
Very simple, but beautiful experience with water and cooking salt can be spent at home and surprise the baby. For the experiment, salt will need, warm water, woolen thread or twig and some bank. It needs to pour water and dissolve a large amount of salt (so much so that the precipitate began to form). The thread is immersed in the solution and leaves alone for 3-5 days. After that, the child can demonstrate the resulting crystals on the thread and explain how they appeared.
Many people believe that if you turn the glass with water, then it will simply turn out, although this statement is completely incorrect. For the experiment, you will need only a dense piece of paper, such as cardboard. They poured into a glass of water, closed with a piece of paper and turn sharply. Now you can go hand, and the liquid is not going anywhere. The bottom line is that the air pressure is outside the glass, much more than in it. Therefore, the piece of paper is kept at the edges, and the water does not fall out.
In the younger school age you can proceed to the study of the most important properties of water. For example, without much difficulties it will be possible to determine: whether the taste of water is that it has color and other simple characteristics. But children at this age will be interested in complex water experiments. Take advantage of the IQ Club Soviets and spend the following types of experiments with liquid surrounding us.
Experience can be carried out with the help of a conventional napkin, multicolored markers and, of course, water. To do this, expand the napkin and cut the long strip of a small width, but for all its length. On the entire surface of the strip, put a multicolored point in the form of beads. Jump it into a glass with water, not reaching the end of several centimeters. The child will see that the water spreads not only down, but also up, staining the napkin with stains of those colors with which the dots were delivered. Explain to the child after the experiment, that the essence of experience is how water applies to any path that finds. In this case, they become cellulose fibers of napkins.
Water for the experiment pour into a glass to the edges. Then dissolve salt or sugar in it (it is better to take a warm liquid) and mix gently. The child will see that despite the filling of a glass of water, we can add a sufficient amount of sugar or salt there, because there is free space between molecules of the substance. In addition, this experiment will make it possible to show that at a certain point, the crystals cease to dissolve, and begin to fall into the precipitate.
Simple, but at the same time informative even for adults, the experiment is carried out as follows:
The meaning of the experiment is quite simple: the boil of water at the time of the strike is formed due to the fact that the air is absorbed through the nasal handkerchief and must pass the obstacle in the form of water, which means that bubbles will appear on its surface.
Only an adult should conduct the next experience, as it implies a chemical reaction. For a child, such an experiment will seem more focus. His essence:
After the components joined the mixture components in the chemical reaction, carbon dioxide is obtained, the pressure of which and contributes to inflats the ball.
Children in high school have already managed to study a lot in the lessons of environmental education, so they do not surprise them with ordinary focus. However, to open several magical properties of water will still work out. Some of the experiments with water that offers the IQ Club will help to better learn its physical and chemical features.
At school, the child is still talking about the cycle of water in nature, but this experiment will allow it clearly. For experience with water, you will need: a plate or a baking sheet made of metal, a can of 3 liters, 5 ice cubes and a little more glasses of boiling water. Performance algorithm:
Children always like various adventures, so in experiments with water, you can add some game torque. Imagine that we found themselves on a uninhabited island and you need to get drinking water. Ening the island, naturally, the ocean with salted water. However, it is possible to extrude fresh liquid. How held:
The essence of this experiments with salty water is that it begins to actively evaporate in the sun. But the spaces where it can be done is not. Therefore, the fluid is condensed again on the surface of the film and it runs into the cup by its walls.
In chemistry, adolescents will be able to spend many more experiences with different states of water. They will convince that many substances have a greater density than it (not in gift the density of water takes place per unit). The IQ Club recommends conducting at home those experiments about which forget in the learning process so that the child is fully developed and interested in the world around.
