Description

technical field

[0001] The invention relates to the related field of physical and chemical equipment, in particular to a multifunctional experimental demonstration instrument for physical and chemical teaching in primary and secondary schools. Background technique

[0002] In the process of physical and chemical teaching in primary and secondary schools, experimental courses are needed to facilitate the students in the physical and chemical experimental courses to understand some physical or chemical knowledge with more concrete knowledge, which is conducive to the dissemination of knowledge. However, in the existing physical and chemical teaching, it is necessary to set up special physical and chemical laboratories. Only doing experimental demonstration on a fixed experimental table makes the experiment have great limitations, which is not convenient for teachers to demonstrate. Contents of the invention

[0003] The object of the present invention is to provide a multifu...
