Simple chemical experiments which can be carried out in house conditions will help to occupy the child and to attract of him interest in natural sciences. With their help it is possible to show that study is not boring, but very entertaining occupation. Adults can organize such experiments also at a children's party. Success of an action is provided!
Storm in a glass of milk
Container with whole milk, liquid detergent, food colorings of several flowers and Q-tip will be necessary for you for carrying out this interesting experiment. Add to the container with milk on a drop of multi-colored food colorings, but do not mix them. Then place a Q-tip which was previously dunked into liquid detergent, into the center of one of bright drops of dye. Milk will start moving, forming a whirlpool and being poured by different flowers. The essence of this experience is that components of detergent and a molecule of fat react. That the experiment took place, it is necessary to use whole milk; fat-free will not approach.
Espionage ink
If to write something on paper a brush for drawing, obmaknuty to apple or lemon juice, the inscription will dry and will disappear. But it will be shown in brown color if to warm up paper on the included lamp. Show to children this focus which they will be able to use in espionage games.
Transparent egg
To make egg transparent, it is necessary to pour vinegar in a glass, to place in it egg and to leave for several days. In acidic environment calcium of which the shell consists will change in solution of acetate of the calcium which does not have dense structure, and egg white and yolk will change structure. We conceal in the way, a certain orange capsule turns out, dense inside and soft outside. If at the turned-off light to light on such egg a small lamp, it beautifully shines as if a bulb.
Cultivation of crystals
It is one of the most popular experiments which parents make in house conditions. Crystals can be grown up from solution of copper vitriol and even plain table salt. But the most interesting are sweet crystals, they not just beautiful, but edible. To grow up crystals, it is necessary to weld syrup from 4 glasses of water and 4 glasses of sugar. Solution needs to be brought to boiling on slow fire, periodically stirring slowly that sugar was completely dissolved. After syrup began to boil, add 6 more glasses of sugar and stir solution. When all sugar is dissolved, syrup can be removed from fire. While it cools down, moisten wooden skewers on which crystals, will grow in water. Then lower wet skewers in syrup, pull out and let's them dry out well. It is necessary in order that on a surface of sticks sugar crystals were fixed. While skewers dry, pour syrup in small jars, having added a little food coloring of different flowers to each of them. Then the dried-out sticks need to be entered accurately in bank with syrup and to suspend on a clothespeg that the skewer did not concern a bottom since crystals need space for free growth. Jars need to be put in light and warm, but not roast, the place where crystals will grow within a week. Observe with the child as the crystal chain changes, and in seven days you will have unusual multi-colored lollipops. Such crystals can be prepared also for a children's birthday.
