Problems solved by technology
[0002] In the process of cultural class learning, because a lot of content is theoretical knowledge in textbooks, such as the concept of atmospheric pressure, it is difficult for elementary school students to understand. If the image of atmospheric pressure can be shown to students through demonstration teaching aids, it will be convenient. Students understand and remember more deeply, but there is no such demonstration teaching aid at present

Embodiment Construction
[0010] Embodiments of the present invention are further described below in conjunction with accompanying drawings:
[0011] Such as figure 1 As shown, the demonstrator for feeling atmospheric pressure includes left and right transparent containers 1 communicated through conduit 7. The container mouth of transparent container 1 is provided with a rubber stopper 4, and glass tube insertion holes are arranged on the rubber stopper 4, and the glass tube 3 Enter the transparent container 1 from the outside through the glass tube insertion hole. One end of the glass tube 3 located in the transparent container 1 is connected to the balloon 2. The rubber plug 4 of the right transparent container is also provided with an air extraction tube 6, and one end of the air extraction tube 6 passes through the rubber The plug 4 enters the transparent container 1, and the other end is connected to the dual-purpose gas cylinder through the rubber tube 5.
[0012] During the demonstration, first...

The invention belongs to the field of teaching aids and particularly relates to an atmospheric pressure feeling demonstration device. The atmospheric pressure feeling demonstration device comprises two transparent containers communicated through a guide tube, wherein container openings of the transparent containers are provided with rubber plugs, the rubber plugs are provided with glass tube insertion holes, glass tubes are inserted into the transparent containers through the glass tube insertion holes, the ends located in the transparent containers, of the glass tubes, are connected with balloons, an exhaust tube is further arranged on the rubber plug of one transparent container, one end of the exhaust tube penetrates through the rubber plug to extend into the transparent container, the other end of the exhaust tube is connected with a dual-purpose air cylinder through the rubber tube. The atmospheric pressure feeling demonstration device is reasonable in structure and simple in operation, can visually demonstrate atmospheric pressure for students through simple demonstration, arouse the students to think deeply in the demonstration process, then performs explanation by being combined with theoretical knowledge on a textbook, accordingly facilitate understanding on the abstract theoretical knowledge of the students, deepens memory of an atmospheric pressure concept and is good in application effect.
Description
technical field [0001] The invention relates to a demonstrator for feeling atmospheric pressure, which belongs to the field of teaching aids. Background technique [0002] In the process of cultural class learning, because a lot of content is theoretical knowledge in textbooks, such as the concept of atmospheric pressure, it is difficult for primary school students to understand. If the image of atmospheric pressure can be shown to students through demonstration teaching aids, it will be convenient Students understand and remember more deeply, but there is no such demonstration teaching aid at present. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a demonstrator for feeling atmospheric pressure which is reasonable in structure, simple in operation and easy for students to understand the concept of atmospheric pressure. [0004] The atmospheric pressure demonst...
