Description
Technical field
The utility model relates to a kind of Political Teaching apparatus, is specifically related to a kind of colleges and universities Political Teaching appurtenance.
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 colleges and universities Political Teaching appurtenance.
Technology contents of the present utility model is: a kind of colleges and universities Political Teaching appurtenance, and comprise support, bucket, bungee, pulley, support is vertically arranged on base; Bungee one end is fixedly connected on base, and the other end is connected on draught line, and mid-stent is provided with fixed pulley, and draught line is walked around fixed pulley and is connected in bucket first; Pedestal upper end is provided with whippletree, and whippletree is provided with bucket second, is provided with the needle-valve corresponding with bucket first and water injection pipe bottom bucket second.
The volume of bucket second is greater than bucket first; Gravity after bucket first fills water is greater than bungee faulting stress.
Beneficial effect
Utilize bucket and rubber band to present to the more intuitively interesting explanation mode of student, contribute to illustrating that quantitative change causes the rule of qualitative change.
Accompanying drawing explanation
Accompanying drawing 1 is colleges and universities' Political Teaching appurtenance structure diagrams.
1 be base, 2 be support in figure, 3 be bucket second, 4 be needle-valve and water injection pipe, 5 be pulley, 7 be draught line, 8 be bungee for bucket first, 6.
Embodiment
See Fig. 1: a kind of colleges and universities Political Teaching appurtenance, comprise support, bucket, bungee, pulley, support is vertically arranged on base; Bungee one end is fixedly connected on base, and the other end is connected on draught line, and mid-stent is provided with fixed pulley, and draught line is walked around fixed pulley and is connected in bucket first; Pedestal upper end is provided with whippletree, and whippletree is provided with bucket second, is provided with the needle-valve corresponding with bucket first and water injection pipe bottom bucket second; The volume of bucket second is greater than bucket first; Gravity after bucket first fills water is greater than bungee faulting stress.
Open the needle-valve under bucket second, water slowly injects bucket first, and along with in bucket first, the increase bungee of the water yield is elongated; After continuing water filling a period of time, bungee can rupture; Illustrate that in political science, quantitative change causes the rule of qualitative change by bungee.
