Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to the apparatus for demonstrating of different vegetation soil erosion situations under a kind of equal condition of raining.
Background technology
Along with going deep into of classroom instruction reform, the effect of multimedia use in teaching becomes increasingly conspicuous.But at vast rural middle school, multimedia can not spread to each classroom, the configuration of audiovisual aids is also very limited.Geography is the combination of natural science and the humanities, has a wide range of knowlege, spatial impression is strong, and a lot of problems are more abstract.The shortage of audiovisual aids, the geographical phenomenon of many directly perception, the geographical object that is difficult to memory are at a loss what to do while making Students ' Learning and are helplessly even felt more uninteresting, allow many students lose interest to geography class, thereby make the teaching of geography class be absorbed in deadlock.
The related object of geographical teaching content often has the indirect in complicacy, extensity, very long property and understanding, makes student be difficult to understanding, understand and grasp, and Students ' Learning gets up, and feels unable to do what one wishes deeply.In geography teaching in middle school, must strengthen object teaching, and the abundant self-control of map, various audiovisual aids, audio-visual education programme media is important channels of object teaching.Should make great efforts creates conditions carries out the utilization of computer auxiliaring teaching means in geographical teaching.Meanwhile, geographical teacher will, in conjunction with reality, scientifically make geographical teaching aid by oneself as much as possible.Only have the effect of bringing into play as much as possible various teaching aids and modern educational technology, could concentrate well student's notice, edify thinking, widen the geographical visual field, deepen knowledge impression, to reach, improve learning efficiency, alleviate the object of study burden of students '.
Make the material source of geographical teaching aid by oneself in life, cost is lower, it is easy, simple to make, teacher, student gather materials on the spot, the geographical teaching aid aided education of doing it yourself to make can reach teaching efficiency directly perceived, vivid, lively, interesting equally, can attract student, also alleviate the difficulty of teacher in teaching, improved the efficiency of teaching of every class; Very practical at the geographical classroom teaching of rural middle school, be instrument capable in geographical teaching, can solve to a great extent the present situation that rural area teaching instrument and equipment lacks.
Summary of the invention
The purpose of this utility model to provide exactly a kind of cost lower, make easy, simplely, at teaching process, can reach intuitively, the apparatus for demonstrating of different vegetation soil erosion situations under the equal condition of raining of vivid, lively, interesting teaching efficiency.
The utility model is achieved through the following technical solutions:
The apparatus for demonstrating of different vegetation soil erosion situations under a kind of equal condition of raining, comprise base 1, bracing frame 2, pole 3, casing 4, beaker 5 and conduit 6, it is characterized in that: described base 1 upper end is connected with bracing frame 2, on bracing frame 2 tops, be provided with casing 4, casing 4 underrun poles 3 are connected with bracing frame 2, below casing 4, be placed with beaker 5, beaker 5 tops are provided with the conduit 6 that is arranged on casing 4 bottoms.
Described casing 4 is divided into framework I 7, framework II 8 and framework III 9, and wherein framework I 7, framework II 8 and framework III 9 front end both sides are equipped with baffle plate 10.
Described baffle plate 10 front ends are also provided with funnel-form through hole 11, at through hole 11, are coated with screen pack 12.
Described conduit 6 upper ends are connected with through hole 11 lower ends, in its other end placement and beaker 5.
Compared with prior art, the beneficial effects of the utility model are:
The base 1 that the utility model provides, bracing frame 2, pole 3, casing 4, beaker 5 and conduit 6 etc. are pinched the teaching aid of the article assembled configuration complexity of coming at one's side conveniently, compare with experimental facilities in the past, have reached material and have been easy to get, make simple.And in daily experiment, this teaching aid can use continuously, simple in structure, can use on a large scale popularization, and the utility model is when test with it, can strengthen interest, can produce fascinating effect, thisly found situation, bring out problem, extend the method for expanding, introduce new class and can reduce the knowledge difficulty on teaching material, strengthen the vivid presentation process of teaching efficiency of this class, make whole teaching process effect remarkable, greatly promoted the aspiration to knowledge of student's Scientific exploration.
The beneficial effects of the utility model are: material source is in life, cost is lower, it is easy, simple to make, teacher, student gather materials on the spot, the geographical teaching aid aided education of doing it yourself to make can reach teaching efficiency directly perceived, vivid, lively, interesting equally, can attract student, also alleviate the difficulty of teacher in teaching, improved the efficiency of teaching of every class.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In figure: base 1, bracing frame 2, pole 3, casing 4, beaker 5, conduit 6, framework I 7, framework II 8, framework III 9, baffle plate 10, through hole 11, filter screen 12.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
An apparatus for demonstrating for different vegetation soil erosion situations under equal condition of raining, comprises base 1, bracing frame 2, pole 3, casing 4, beaker 5, conduit 6, framework I 7, framework II 8, framework III 9, baffle plate 10, through hole 11 and filter screen 12.
As shown in drawings, wherein base 1 upper end is connected with bracing frame 2, on bracing frame 2 tops, is provided with casing 4, and casing 4 underrun poles 3 are connected with bracing frame 2, are placed with beaker 5 below casing 4, and beaker 5 tops are provided with the conduit 6 that is arranged on casing 4 bottoms.
Wherein casing 4 is divided into framework I 7, framework II 8 and framework III 9, and wherein framework I 7, framework II 8 and framework III 9 front end both sides are equipped with baffle plate 10.
Wherein at baffle plate 10 front ends, be also provided with funnel-form through hole 11, at through hole 11, be coated with screen pack 12.
Wherein conduit 6 upper ends are connected with through hole 11 lower ends, in its other end placement and beaker 5.
The utility model is when concrete use, first give framework I 7, framework II 8 and the interior covering of framework III 9 by close-rare-without three blocks of loess of turf, with the pressure spray kettle of inflation, give respectively framework I 7, the water of framework II 8 and the interior sprinkling equivalent of framework III 9, simulate identical rainfall state, due to framework I 7, framework II 8 and framework III 9 are and are obliquely installed, being sprayed at three blocks of water on loess can be along trickling, by baffle plate 10, finally converge in through hole 11, through the conduit being connected with through hole 11 lower ends, enter in beaker 5, in this process, screen pack 12 can filter turf, but do not filter loess.
Owing to being coated with the turf of different densities on three blocks of loess, draw conclusion time " vegetation coverage is higher; the ability of water conservation is stronger (water in beaker 5 is fewer) just, and the situation of soil erosion just relatively can especially severe (loess in beaker 5 is fewer) ".
The teaching efficiency that the utility model is directly perceived, interesting, can attract student, has also alleviated the difficulty of teacher in teaching, has improved the efficiency of teaching of every class.
