Description

A teaching tool for the Marxist theory of material motion

technical field

The utility model relates to a teaching tool, in particular to a teaching tool for the Marxist material movement theory.

Background technique

The teaching of the principles of Marxism is boring and abstract, especially for beginners who feel that this subject is empty, monotonous, and boring. It can be said that the teacher teaches hard and the students learn painfully. "Interest is the best teacher". Once students' interest is stimulated, they will have endless thirst for knowledge and exploration. Therefore, in order to mobilize students' interest in learning the principles of Marxism, teachers must turn boring into vivid Decay is magical, so that students can see its shape and hear its sound, so as to deepen the impression and trigger thinking.

In the teaching of Marxist principles, the theory related to the part of material movement is that the movement of matter must take a certain form. According to the situation revealed by modern science, there are roughly five basic forms of material motion: mechanical motion, physical motion, chemical motion, and biological motion. social movement. There are connections between various forms of movement, and higher-level forms of movement are formed on the basis of lower-level forms of movement; higher-level forms of movement include lower-level forms of movement, and various forms of movement can be used under certain conditions. Mutual transformation, but motion is eternal, neither created nor destroyed.

The patent with Chinese Publication No. CN202748998 U discloses "an observation bottle suitable for teaching the principles of Marxism". The utility model effectively improves the students' interest in learning, but the utility model has a relatively single movement form, and there are no different forms of movement. transformation.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

As shown in Figure 1, a kind of teaching tool that is used for the theory of motion of Marxism matter, comprises base 1 and experiment bottle 2, and base 1 comprises base 3, first baffle plate 4 and second baffle plate 5, first baffle plate 4 is fixedly connected to the left side of the base 3, the second baffle 5 is fixedly connected to the rear side of the base 3, and the upper end of the second baffle 5 is provided with a convex lens 6; the experimental bottle 2 includes a bottle body 7, a feeding bottle 8, a balance device 9, The discharge pipe 10 and quicklime placement tank 11, the bottle body 7 is fixedly connected to the base 3, the top of the first baffle plate 4 and the second baffle plate 5 are parallel to the top of the bottle body 7, the bottle body 7 is transparent, and the discharge bottle 8 is connected to the left side of the upper end of the bottle body 7, the balance device 9 is connected to the inside of the experimental bottle 2, the discharge pipe 10 is located at the lower end of the bottle body 7, and the quicklime placement tank 11 is placed at the lower end of the discharge pipe 10.

The discharging bottle 8 is provided with a regulating valve 12, through which the discharging speed of the discharging bottle 8 is adjusted, which is convenient for students to observe.
