Abstract
The utility model discloses a demonstration teaching aid is used in physical experiment teaching, including the support, be equipped with magnetic sheet and blackboard two parts on the support, be equipped with the mobilizable magnetism piece of several on the magnetic sheet, but the experiment process is write on the blackboard, support both sides sub -unit connection has the telescopic link, and the telescopic link is fixed and is being supported the base, and the magnetic sheet includes the blank, and the permanent magnet that has polylith range in good order is inlayed to the blank lower part, and the blackboard outside is equipped with the ledge for chalk on blackboard. The beneficial effects are that: can show experimentation abundant, directly perceived to whole students can see the experimentation clearly in making the classroom, improve the quality of teaching.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically relates to a kind of physics experiment teaching presentation tool.
Background technology
In Physical Experiment Course teaching process, general is all adopt on teacher's prior theory course to explain, after do in laboratory demonstration experiment teaching pattern, there is following drawback in this template: during (1) Classroom theory explanation experimentation, general is all teacher's Freehandhand-drawing experimental apparatus and explanation experimentation on blackboard, more abstract, it is large that student understands experiment difficulty; (2) demonstration program of laboratory, general employing be that teacher tests on laboratory table, student is trapped among laboratory table surrounding viewing experimentation, like this, because laboratory table surrounding volume is limited, the classmate standing in rear row easily can't see experimentation, and due to light, angle problem, the classmate being in remote angle also easily can't see experimentation, and serious has had influence on the quality of instruction of Physical Experiment Course.
Utility model content
Problem to be solved in the utility model be to provide a kind of easy to use, fully, intuitively can show experimentation, and make whole student in classroom clearly see the physics experiment teaching presentation tool of experimentation clearly.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of physics experiment teaching presentation tool, comprise support, it is characterized in that: described support is provided with magnetic sheet and blackboard two parts, described magnetic sheet is provided with several moveable magnetic block on the surface, described blackboard can carry out experimentation and write; Described support two side lower part is connected with expansion link, and described expansion link is fixed on base for supporting.
Preferably, above-mentioned a kind of physics experiment teaching presentation tool, wherein said magnetic sheet comprises blank, and described blank bottom is inlaid with the permanent magnet of polylith arrangement in good order.
Preferably, above-mentioned a kind of physics experiment teaching presentation tool, is provided with ledge for chalk on blackboard outside wherein said blackboard.
Technique effect of the present utility model is mainly reflected in: magnetic sheet is connected in magnetic mode with magnetic block, can realize the displaying of the Physical Experiment such as power supply, mechanics process fully intuitively; The setting of blackboard, experimentation book can write on the blackboard by teacher, coordinates the displaying of experimentation on magnetic sheet simultaneously, is more conducive to the understanding of student; Expansion link can realize the adjustment of the utility model height, can adjust the height of this presentation tool, improve the quality of teaching according to the differing heights of teacher and student; Ledge for chalk on blackboard can store chalk, directly can get chalk from ledge for chalk on blackboard and use, improve efficiency of teaching when writing.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, a kind of physics experiment teaching presentation tool, comprises support 1, and described support 1 is provided with magnetic sheet 2 and blackboard 3 two parts, and described magnetic sheet 1 is provided with several moveable magnetic block 4 on the surface, described blackboard 3 can carry out experimentation and write; Described support 1 liang of side lower part is connected with expansion link 6, and described expansion link 6 is fixed on base for supporting 7, and described magnetic sheet 2 comprises blank 21, and described blank 21 bottom is inlaid with the permanent magnet 22 of polylith arrangement in good order, is provided with ledge for chalk on blackboard 5 outside described blackboard 3.
In physics experiment teaching process, experimentation can be write on blackboard 3 by Physical Education Teacher, then magnetic block 4 is assumed to be test articles, multiple magnetic block 4 is needed according to experiment the appropriate location being placed on magnetic sheet 2, complete the demonstration of experimentation, student, in viewing experimental demonstration and do-it-yourself experimentation, open-and-shutly can see the experimentation on magnetic sheet 2 and the experimental procedure on blackboard 3 clearly, improve learning efficiency.
Chalk can be placed in ledge for chalk on blackboard 5, and teacher writes in writing on the blackboard process directly can take chalk from ledge for chalk on blackboard 5, saves instructional blocks of time.
When Physical Education Teacher writes writing on the blackboard and explanation experimentation, according to self height, the height of the utility model body can be adjusted by the expansion link 6 between base for supporting 7 and support 1; After classroom says that solution preocess terminates, adjustment expansion link 6 can be continued through, heighten the height of the utility model body, so that student better can see the experimental demonstration on magnetic sheet 2 and the writing on the blackboard on blackboard 3 clearly, improve conventional efficient.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
