Spherical virus model teaching aid

Abstract

The invention discloses a spherical virus model teaching aid, which is characterized by comprising a spherical body, a structure rod and a triangular block, wherein the spherical body is a sphere, the structure rod is a cuboid of which the top surface is uniformly provided with four hemispheres along the length direction, and the triangular block is a regular triangular prism of which the top surface is uniformly provided with six hemispheres; and the spherical body as vertexes, the structure rod as edges and the triangular block as surfaces together form a complete icosahedron, the spherical body is provided with a furcella, the furcella is a sphere of which the bottom is provided with a connecting rod, one end of the connecting rod is connected with the sphere, and the other end of the connecting rod is connected with the spherical body. According to the invention, observers can clearly understand the appearance, structure and working principle of a spherical virus; meanwhile, the transportation space can be saved, and the transportation cost can be lowered.

Description

technical field [0001] The invention relates to a model teaching aid, in particular to a virus model teaching aid. Background technique [0002] The development of microbiology has promoted the progress of human beings, including the contribution to the basic theoretical research of life sciences, and the promotion of production practices such as medical care, industrial fermentation, agricultural production and environmental protection. [0003] However, the characteristics and limitations of microorganisms, such as the small individual and unobvious group appearance, have led to a long-term lack of understanding of the large number and wide distribution of microorganisms. After the rise of microbiology, more and more fields are applied to microbiology, and more and more people study microbiology. In the process of study and research, it is necessary to observe with a microscope to understand the shape and structure of microorganisms. However, in the process of teaching, ...

Problems solved by technology

However, in the process of teaching, if you want to explain the characteristics of a certain microorganism to students, it is not enough to rely solely on observing the microscope, because everyone sees different pictures and understands different things, and the teacher has no way It is very intuitive to point out the specific structure of microorganisms

[0004] Some viruses are often encountered in microbiology, pathology, etc., and then the teacher explains the morphology and structure of these viruses. Usually, only photos of images from electron microscopes or schematic diagrams of structures can be used, but these pictures can only show viruses. The shape and appearance of the virus cannot show a three-dimensional structure, let alone visually see the internal structure of the virus

However, some existing teaching aids are fixed structures, which cannot allow students to combine them by hand. Therefore, model teaching aids with fixed structures are not conducive to deepening memory.
