Plastic Yangtze river model

Abstract

The invention belongs to the technical field of teaching tools, and relates to a geographic teaching aid, particularly a plastic Yangtze river model. The plastic Yangtze river model is composed of a thermoplastically molded hard plastic film shell. According to the technical scheme of the invention, the above prepared plastic Yangtze river model is rectangular block-shaped, and the upper surface of the prepared plastic Yangtze river model is colorfully printed and thermoplastically molded to be formed high in west and low in east. Meanwhile, the hard plastic film shell represents the convex and concave characteristics of the Yangtze river basin terrain. Therefore, the geographical knowledge of the Yangtze river can be expressed more intuitively and more vividly compared with the effect of images and texts on geographic textbooks as plane presswork. The effect of teaching through lively activities is realized, and the interest of students in learning the Yangtze river geographical knowledge is stimulated. Therefore, the knowledge is more easily understood, and is easy to learn and remember. Compared with a sand table type Yangtze river model, the above plastic Yangtze river model is light in weight, convenient to transport and carry, easy in manufacture and low in cost, thus being suitable for further popularization as a teaching aid. The plastic Yangtze river model can be not only used as a geographical teaching tool, but also used as a toy. As a result, the plastic Yangtze river model is more suitable for use as a tourist souvenir of the Yangtze river.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and relates to a geography teaching aid, in particular to a plastic model of the Yangtze River. Background technique [0002] The Yangtze River is the largest river in China and the third largest river in the world. It originates from the roof of the world - the southwest side of Dandongela Peak in the Tanggula Mountains on the Qinghai-Tibet Plateau.

Problems solved by technology

Most people learn about the geography of the Yangtze River from geography textbooks, but geography textbooks are flat-printed graphics and texts, which are boring and not intuitive. Although the three-dimensional sand table model of the Yangtze River is intuitive, it is cumbersome and difficult to transport and Portable and costly, cannot be used as a teaching aid
