Abstract
A kind of politics lesson assistant teaching aid, comprise support, bucket, balloon, support is vertically arranged on base, and frame upper is provided with whippletree; Whippletree is provided with bucket first, is provided with needle-valve bottom bucket first, and below needle-valve, correspondence is provided with transparent bucket second and balloon; Balloon inflation mouth is strapped on needle-valve by strapping, and balloon spheroid is placed in bucket second; Bucket second internal diameter and balloon external diameter match; The explosion that is constantly deflected into according to balloon illustrates that in political science, quantitative change causes the rule of qualitative change.
Description
Technical field
The utility model relates to teaching equipment field, particularly relates to a kind of politics lesson assistant teaching aid.
Background technology
When Political Teaching, teacher to quantitative change to qualitative change process instruction, mostly be and use books, chalk and blackboard to impart knowledge to students to student, and the content that politics lesson relates to is not only extensive, and abstract, only rely on books, chalk and blackboard very abstract, be not easy to student and understand, it is more difficult that student accepts, and teaching efficiency is poor.
Utility model content
In order to solve uninteresting, the abstract problem of political classroom books explanation, the utility model devises a kind of politics lesson assistant teaching aid.
Technology contents of the present utility model is: a kind of politics lesson assistant teaching aid, comprises support, bucket, balloon, and support is vertically arranged on base, and frame upper is provided with whippletree; Whippletree is provided with bucket first, is provided with needle-valve bottom bucket first, and below needle-valve, correspondence is provided with transparent bucket second and balloon; Balloon inflation mouth is strapped on needle-valve by strapping, and balloon spheroid is placed in bucket second; Bucket second internal diameter and balloon external diameter match.
Beneficial effect
Utilize the balloon constantly injecting water deformation can occur and even burst to illustrate that quantitative change causes the rule of qualitative change, more intuitively interesting, help attract attention of student and improve class efficacy.
Accompanying drawing explanation
Accompanying drawing 1 is politics lesson assistant teaching aid structure diagram.
1 be base, 2 be support in figure, 3 for bucket first, 4 be balloon, 5 be needle-valve, 6 for bucket second.
Embodiment
A kind of politics lesson assistant teaching aid, see Fig. 1: comprise support, bucket, balloon, support is vertically arranged on base, and frame upper is provided with whippletree; Whippletree is provided with bucket first, is provided with needle-valve bottom bucket first, and below needle-valve, correspondence is provided with transparent bucket second and balloon; Balloon inflation mouth is strapped on needle-valve by strapping, and balloon spheroid is placed in bucket second; Bucket second internal diameter and balloon external diameter match.
Open needle-valve, to the continuous water-filling of balloon, balloon is because the pressure action of water produces deformation; Along with water injection rate constantly increases, when balloon deformation exceedes the deformation range that itself can bear, balloon bursts; The explosion that is constantly deflected into according to balloon illustrates that in political science, quantitative change causes the rule of qualitative change.
In this device course of work, people can carry out the deformation of observation baloon by transparent bucket second, can ensure again that balloon burst is that water can not be sprinkled upon dais and soaks books and desk simultaneously.
