Every talented teacher knows to teachthe child something new, it needs to be interested. Today, you can find ready-made sets for creativity and entertaining experiences that can not only cause the child's interest, but also keep it for a long time. Try to grow at home "magic" crystals - this experiment will bring a lot of pleasure not only to children, but also to their parents.
Sets for crystallization at home
Experience in growing crystals was carried out at school by our parents. Today, on the market, you can find ready-made kits for conducting such an experiment. What are their advantages?
Using a ready-made set, a child can not onlygrow "magic" crystals yourself. On sale you can find curly bases for crystallization, beautiful coasters, as well as a set of personal protective equipment for a young chemist. Often also in the kit there is a memo with a scientific explanation of the experiments and questions for testing the acquired knowledge.
Complete sets of young chemists
In each set of "Magic Crystals" are availablereagents for chemical experience and the basis on which they will be grown. Also in the kit can be a container for growing and sticks to stir the solution. Expensive sets are sometimes completed with an apron, gloves and glasses. These means of protection for a young experimenter are, of course, intended only for creating an entourage. Experience with growing crystals is completely safe.
On sale you can find kits withbases-stones or figured. Very interesting is, for example, the version of "Magic Crystals: Christmas tree". In this set, the whole process takes place on a foundation made in the form of a Christmas tree. As a result of the experiment, we get an interesting article - a Christmas tree, consisting of greenish crystals.
"Magic crystals": instructions for growing a house
Before you begin your entertaining study, read carefully the manual for using all the components of the selected set. The standard work plan is as follows:
- Place the crystallization base in the growing container.
- Fill with hot water the appropriate reagent.
- Now you can add to the solutionpowder for crystallization. Pour it should be so much that there are undissolved grains. Once the active substance has ceased to dissolve, you have a saturated solution. In this case, a few grains of the reagent should remain with you.
- Then pour the solution into the growth tank so that the liquid completely conceals the base. In this case, the precipitate must remain in the original container.
- Then throw the remaining grains of the reagent onto the bases for crystallization. This is the "seeds" from which your "magic" crystals will grow.
If you pour a solution on yoursurface emerged individual crystals, immediately remove them. Now it only remains to remove the container to a safe place and leave it for a while. Cover it with a sheet of paper from the top, if there is no cover in the kit.
The growth of crystals will begin almost immediately.Do not forget to follow the container. Drain the solution as soon as one of the crystals appears on the surface. After this, it is necessary to pull them all out and dry it for 24 hours.
What to do with the grown crystal?
Experience can be considered complete as soon as the crystallization process has ended. Where to put ready "magic" crystals? The instruction from the kit usually does not answer this question.
If you do everything according to the instructions, the crystalwill turn out beautiful and interesting. You can simply store it for memory or use it in some crafts. Particularly interesting is the crystallization on a figured basis. The finished product does not need an additional decor and in itself looks interesting and unusual.
Safety in the conduct of crystallization experiments
In the instructions of the set for growing crystalsit is usually said that children under 14 should be under the supervision of adults to carry out the experiment. Observe this simple rule, and experience will bring you only positive emotions.
The reagents included in the kit are safe.But, of course, they can not taste, and if you get on your skin, you should immediately wash it off with water. Completely safe and ready-made crystals, they are strong enough, they can be picked up. Try to avoid contact with water - the liquid can destroy the result of your experience.
Price of sets for crystallization of the house
And now we calculate how much it costs to growcrystal at home. The cost of small sets designed to grow small items is usually 150-200 rubles. Interesting sets, which include additional elements and figured bases, can have a higher price. For example, "Magic Tree" (crystals grow on the branches of the stem) costs 250 rubles.
Choose sets for your taste.If desired, you can grow a whole collection of crystals of different shapes and colors. The most important thing is to carefully study the instructions, as different sets may differ slightly from one manufacturer to another.
Reviews about "Magic Crystals"
Crystallization kits appeared on the shelvesshops several years ago. During this time, many of our compatriots tried to grow a crystal at home. A large number of buyers liked this interesting and entertaining experience.
Sets of "Magic Crystals" reviews havepositive. This is a great way to tell the child about chemical reactions. Every parent knows that sometimes it is not at all easy to direct the energy of the child in the right direction and to something really fascinate. And growing crystals is not only an interesting experiment, but also a hobby for the whole family.
Although among the buyers of the described sets there is alsothose who remained dissatisfied. It happens that sometimes the crystals just do not start to grow. There can be two reasons: failure to comply with the rules for conducting the experiment or the manufacturer's marriage (for example, incorrect equipment with reagents).
Is it possible to grow a crystal without a special kit?
The experience of crystallization can be done in domesticconditions without any special substances and devices. For this experiment, you will need ordinary table salt. Dilute the saturated solution by adding 200 grams of hot water at least 2 tablespoons of the selected substance. Throw a small pebble into the liquid, leave the container for a week in a cool place. As a result, you will get a base covered with crystals of salt. It can be carefully removed from the solution and dried on a paper towel.
However, keep in mind that salt crystalsfragile enough. The value of this experience lies in the process itself. If you want to save something for memory, it makes sense to purchase a ready-made set of "Magic Crystals." Using real reagents and convenient devices, you can observe an entertaining chemical process. And as a result, you will get beautiful colorful crystals that have good transparency and strength.
