Embodiment Construction

[0012] Such as figure 1 As shown, the invention has a transparent hollow ball (3) (or buckled together with two hemispherical transparent covers), with an inner diameter of about 20 cm, and is separated from top to bottom by three layers of window screens (1) inside the transparent hollow ball. Two parts, the lower part is the wind tunnel (5), its function is to let the wind blow to the specified direction, the upper part is equipped with a grid (2), the upper cavity is divided into two parts, the left and the right, the grid The gap is larger than the window screen, and the gap of the window screen cannot pass through the small plastic balls, it is only used for ventilation, and the gap of the grid can pass through the small plastic balls. The lower end is provided with a cube base, and a fan is installed in the center of the base.

Abstract

The invention relates to a teaching tool, and particularly relates to a teaching tool for simulating chemical balance and osmosis. A teacher difficultly explains a chemical balance principle. The chemical balance is a very abstract concept, and students receive the abstract concept difficultly because the concept, the characteristic and the formation process of the chemical balance state are unclear. The balance and osmosis demonstrator provided by the invention is capable of visualizing the micro and abstract chemical reaction principle, simulating the chemical balance state formation process and characteristics by using a visible macroscopic phenomenon, and simulating an osmosis process of a semipermeable membrane and a diffusion process of a cell membrane. The students can visually know the abstraction problem through observing the macroscopic phenomenon, and more durably memorizes the abstraction and learns the abstraction at higher efficiency.

Description

technical field [0001] The invention relates to a teaching tool, which is a teaching tool for simulating chemical balance and penetration. Background technique [0002] There are currently no teaching aids for simulating chemical equilibrium and penetration in the market, and it is very difficult for teachers to explain the principles of chemical equilibrium. Chemical balance is a very abstract concept. It will be very difficult for students to accept the principle of chemical reactions clearly described in words. Almost all students feel that the chapter of chemical balance is the most difficult to learn. The reason is that the concept, characteristics, and formation process of the chemical equilibrium state are unclear. Contents of the invention [0003] In order to solve the above problems, I invented a balance and penetration demonstration instrument. The demonstrator can visualize microcosmic and abstract chemical reaction principles. Use visible and tangible macro...
