Abstract: 
When I was working at the school, I had difficulty explaining the topic due to the lack of laboratory equipment, 
sometimes these phenomena and processes are so unusual that even hardworking students find it difficult introduce them to your 
mind. Many objects and phenomena considered in courses of electricity, magnetism, molecular and nuclear physics with virtually 
no than are not associated in ordinary life. so I decided to use this device to explain the lessons. This helped me a lot to achieve a 
high score. Using this article, I will explain the principle of construction and operation of a mini- Installations.

INTRODUCTION 
To help students understand the basic principles of phenomena, their schematize, linking with previously studied models. For 
example, talking about the thermal motion of molecules of an ideal gas, consider their collision as absolutely elastic collision of 
hard balls, and the movement between collisions as the uniform motion of a material point. These models and phenomena have 
already been studied. in the course of mechanics, therefore, must be mastered by students and understandable to them. 
To improve the visibility of this method of explaining complex physical of phenomena it is proposed to use mini-installations 
simulating these phenomena 
visually. When using these settings, this phenomenon may actually not take place. It is like a computer simulation when all events 
unfold on the monitor screen. The difference is that they manage the process themselves students, not a computer. An example is a 
mini-installation, Stern's modeling experience in measuring molecular velocities.
