Description

Technical Field

[0001] The invention relates to the technical field of physical experiments, in particular to buoyancy experiment teaching equipment used for physical experiments. Background Art

[0002] Physics teaching refers to helping students master the concepts, laws and experimental methods of physics through a series of teaching activities, and cultivating students' scientific thinking and problem-solving abilities. Physics teaching not only includes the imparting of theoretical knowledge, but also emphasizes experimental operations and the cultivation of problem-solving abilities. The buoyancy experiment is an experiment in physics used to study the buoyancy of objects in liquids. With the continuous development of physics teaching, various teaching equipment have emerged to help students master knowledge points, such as a buoyancy experiment teaching equipment used in physics experiments.

[0003] At present, the buoyancy experiment teaching equipment on the market mainly focuses on the research of changing the concentration of solution. The existing buoyancy experiment teaching equipment is generally composed of a support frame, a dynamometer, a measuring bottle and an experimental object. The experimental object and the dynamometer are fixed, and then the experimental object is lifted by the dynamometer and placed in a measuring bottle with an aqueous solution. The change of the dynamometer is observed to show the change of buoyancy, and the measuring bottle is tilted to show the direction of buoyancy. However, when conducting experiments, the existing teaching equipment needs to tilt the measuring bottle for a long time, which is more laborious and difficult to stabilize the measuring bottle. Moreover, the change of the dynamometer can only be observed when approaching, and the buoyancy change cannot be displayed to most students, which is not conducive to teaching students at a long distance. Therefore, it is proposed to slowly and stably change the horizontal angle of the measuring bottle, and continuously and stably tilt the measuring bottle to show the direction of buoyancy, and the scale change of the dynamometer can be displayed through a display, so that most students can watch it synchronously, which is conducive to teaching. A buoyancy experiment teaching equipment for physical experiments is proposed. Summary of the invention

It solves the problem that the existing teaching equipment needs to tilt the measuring bottle for a long time when conducting experiments, which is relatively laborious and difficult to stabilize the measuring bottle, and the changes in the dynamometer can only be observed when approaching, and the buoyancy changes cannot be displayed to most students, which is not conducive to teaching students at a long distance.
