Abstract

The invention provides a level gauge, which relates to the field of a scientific experiment device and teaching and solves the problems that a corresponding experimental instrument is lacked in the prior art, and the function of the existing experimental instrument is single. The level gauge comprises a base and a vertical rod fixed onto the upper end of the base, wherein a transverse rod is fixedonto the upper end of the vertical rod; a bob weight is connected under the transverse rod through a soft rope; a sharp end is made on the lower end of the bob weight; a reference block is fixed ontothe upper end of the base; a sharp end is made on the upper end of the reference block; and the reference block is arranged right under the bob weight. The level gauge is made from easy-to-acquire articles such as plastic pen rods and plastic bottle caps as materials; the structure of the experimental instrument is simple; and the manufacturing is easy, so that the level gauge is suitable for students to make by the selves and to make at home.

Description

Technical field: [0001] The invention relates to the field of scientific experiment equipment and teaching, in particular to a level measuring instrument. Background technique: [0002] At present, most of the experimental devices used for teaching are complex in structure, single in function, and not widely applicable. Moreover, there are almost no experimental devices on the market made for experiments on the basic principles of physics learning. As a result, elementary and middle school students who are new to physics cannot clearly understand basic physics knowledge. In addition, some theoretical concepts in physics, if not explained Analysis, it is difficult for those novice students to understand, which makes most students lose interest in learning. At the same time, most of the scientific experimental instruments can only be used for teaching, and most of the time can only be placed in the warehouse, and cannot be displayed as decorations or handicrafts. Therefore, ...
