摘要：Ways of laboratory synthesis of solid inorganic substances by analogy to the processes in the nature are considered. Techniques of synthesis of inorganic compounds in gels as a result of reactions with the counter or unilateral diffusion, sold in conditions of school chemical laboratory are resulted. It is shown, that the offered techniques can be used at the organization of design activity of pupils, and also at carrying out of the integrated lessons. The contents of lessons in chemistry-geography on a theme "Mineralization and structure of minerals" and in chemistry-biology on a theme "Crystallization of inorganic salts in alive organisms" is considered. It is shown, that modeling of natural processes serves in laboratory conditions means of formation of representations about material unity of the world surrounding us.
