Abstract

The invention relates to a swinging ball experiment demonstration device, and especially relates to a swinging ball experiment demonstration device for a classroom experiment. A technical problem to be solved is to provide the swinging ball experiment demonstration device for the classroom experiment. In order to solve the above problem, the invention provides the swinging ball experiment demonstration device for the classroom experiment. The device comprises a demonstration box, a first stay wire, a swinging ball, a placement box, and a display board. The top of the interior of the demonstration box is connected with the first stay wire, and the bottom end of the first stay wire is connected with the swinging ball. The internal bottom of the demonstration box is provided with a placement box, and the placement box is located below the swinging ball. The center of the top of the placement box is provided with an opening, and the internal bottom of the placement box is connected with a lifting deice. The upper end of the lifting device is connected with a rotating device, and the upper end of the rotating device is connected with the display board. Through the linkage of the lifting device and the rotating device, the device completes the demonstration of the classroom experiment, can demonstrate a swinging ball experiment, and also brings convenience to a teacher for the classroom teaching.

Description

technical field [0001] The invention relates to a swinging ball experimental demonstration device, in particular to a swinging ball experimental demonstration device for classroom experiments. Background technique [0002] Classroom is a place for students to learn. It provides opportunities for students to practice in class, and allows students to have practical experience in specific situations, so that they can understand the truth, experience emotions, reflect on their own actions, and regulate behaviors in activities. [0003] Experiment is one of the basic methods of scientific research. According to the purpose of scientific research, eliminate the influence of the outside world as much as possible, highlight the main factors and use some special instruments and equipment to artificially change, control or simulate the research object to make certain things happen or reproduce, so as to understand natural phenomena, Nature, natural law. [0004] Through classroom de...
