Abstract
A teaching aid for demonstrating submarine diving and floating principle, characterized in that it comprises a demonstration table, a support is disposed on the demonstration stable vertically, side wall of the support is disposed with a collar, the collar is sleeved with a soft container therein, one end of the soft contained is a wide-necked bottle body, the soft container is filled with a part of liquid, several Cartesian divers floats on liquid in the soft container, the Cartesian diver is a transparent bottle body comprising one end with a capsule and one end with a wide-necked transparent bottle body, the side wall of the support is disposed with a pressure regulating screw rod, the front end of the pressure regulating screw rod is connected with a pressure plate firmly leaning against the side wall of the soft container, the opening of the soft container is disposed with a sealing plug, the side wall of the Cartesian diver is disposed with a voice sheet. The utility model has simple structure, operation convenience, capable of demonstrating submarine diving and floating principle, convenient for teachers to accomplish teaching task and enhancing studying interest and practical ability of the students, beneficial for analysis ability and problem solving ability of the students.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of teaching aid of demonstrating submarine sink-float principle, is to having replenishing of physics teaching in secondary school apparatus kind now, belonging to the school supply and stationery category.
Background technology
At present, middle and primary schools' teaching aid kind is a lot, but function singlenesses all just designs at the content that needs separately to show.In junior middle school physics teaching, make the student grasp the knowledge of buoyancy and pressure relation by experiment, particularly demonstrating submarine sink-float principle is very important content in the physics teaching, yet be again one of the important of physics lesson and the course of beyonding one's depth, student and teacher press for teaching aid targetedly, the teaching material of existing explanation submarine sink-float principle, DeGrain, and can not intuitively observe, be difficult to make the undergo proof procedure of buoyancy and pressure relation of student, thereby bring certain difficulty to teaching, even have influence on student performance and learning interest.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improves by research, provides a kind of teaching aid of demonstrating submarine sink-float principle.This novel teaching aid is simple in structure, workable, can demonstrate the process that the submarine sink-float produces.
The technical scheme that the utility model provides is: the teaching aid of this demonstration submarine sink-float principle, be characterized in a demonstration platen, erect on the Demonstration table support is arranged, the sidewall of support is provided with a collar, be with transparent flexible container in the collar, flexible container is the uncovered bottle of an end, fill partially liq in the flexible container, floating on the liquid level in the flexible container have a Cartesian diver, this Cartesian diver is an end band capsule, the other end is uncovered transparent bottle, also be provided with the pressure regulation screw rod on the described rack side wall, the front end of pressure regulation screw rod joins with the pressure plare that abuts against the flexible container sidewall, described flexible container open-mouth is provided with sealing-plug, also is provided with the voice sheet on the sidewall of described Cartesian diver.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, workable, can demonstrate the process that the submarine sink-float produces, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to the analysis and the problem-solving ability of cultivating the student.
Description of drawings
Fig. 1 provides the structural representation of embodiment for the utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As Fig. 1～shown in Figure 2, the teaching aid of this demonstration submarine sink-float principle, a demonstration platen 8 is arranged, erect on the Demonstration table 8 support 5 is arranged, the sidewall of support 5 is provided with a collar 6, be with transparent flexible container 1 in the collar 6, flexible container 1 is the uncovered bottle of an end, fill part water 4 in the flexible container 1, floating on the liquid level in the flexible container 1 have a Cartesian diver 3, this Cartesian diver 3 is end band capsules, the other end is uncovered transparent bottle, also be provided with pressure regulation screw rod 7 on described support 5 sidewalls, the front end of pressure regulation screw rod 7 joins with the pressure plare 9 that abuts against the flexible container sidewall, and flexible container 1 open-mouth is provided with sealing-plug 10, also is provided with voice sheet 2 on the sidewall of Cartesian diver 3.
During demonstration, slowly regulate pressure regulation screw rod 7, the gas pressure intensity in the flexible container 1 is constantly increased, the water 4 in the flexible container 1 enters in the Cartesian diver 3, makes it gravity and strengthens, thereby finish floating, the overall process that suspends and sink of simulated dive ship.Owing to have voice sheet 2 on the sidewall of Cartesian diver 3, when Cartesian diver 3 suspends, can hear sound.By demonstration the student is intuitively grasped: the knowledge point of buoyancy and pressure relation, submarine sink-float principle and liquid transaudient.
