Abstract
The utility model discloses a kind of biological demonstration teaching aid, it comprises magnetic sheet (1), adhesive tape (7), magnetic fittings and oral groove layer (8), magnetic sheet (1) is provided with groove (9), oral groove layer (8) is attached on magnetic sheet (1), and adhesive tape (7) is arranged on the surrounding of magnetic sheet (1); Described magnetic fittings comprises hemisphere (3), ellipse (4), circular slab (5) and tubular plate (6), magnetic fittings is adsorbed on magnetic sheet (1), it also comprises adhesive tape (2), and adhesive tape (2) is attached on magnetic sheet (1).The utility model can reflect the morphosis of paramecium, helps student to understand the morphosis of paramecium; Inspiring student when learning biological knowledge simultaneously, oneself can make some small articles and helping it to understand biological knowledge.
Description
Technical field
The utility model relates to a kind of biological demonstration teaching aid.
Background technology
At present, the teaching aid used in domestic bioconversion medium process is generally colored wall chart or lantern slide.Although colored wall chart or lantern slide directly perceived, eye-catching, also only rest on the aspect of " seeing ", the manipulative ability of student can not be strengthened; Current student often can not understand the morphosis of paramecium well when learning biological course.Therefore, I can help again student to understand the demonstration teaching aid of the morphosis of paramecium as a kind of students ' practical ability that can either strengthen of the obligated making of teacher of long campaigns bioconversion medium work.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of biological demonstration teaching aid, strengthens the manipulative ability of student, helps student to understand the morphosis of paramecium.
The purpose of this utility model is achieved through the following technical solutions: a kind of biological demonstration teaching aid, it comprises magnetic sheet, adhesive tape, magnetic fittings and oral groove layer, magnetic sheet is provided with groove, and oral groove layer is attached on magnetic sheet, and adhesive tape is arranged on the surrounding of magnetic sheet; Described magnetic fittings comprises hemisphere, ellipse, circular slab and tubular plate, magnetic fittings is adsorbed on magnetic sheet, described circular slab quantity is multiple, wherein two circular slabs are wound with tubular plate all around, deserving to be called respectively and stating two circular slabs is circular slab A and circular slab B, circular slab A is adsorbed in the top of magnetic sheet, and circular slab B is adsorbed in the bottom of magnetic sheet.
The utility model also comprises adhesive tape, and adhesive tape is attached on magnetic sheet.
The beneficial effects of the utility model are: magnetic fittings can be put on magnetic sheet by student, is combined into the morphosis of paramecium, are strengthened the manipulative ability of student by this simple anabolic process, help student to understand the morphosis of paramecium; Inspiring student when learning biological knowledge simultaneously, oneself can make some small articles and helping it to understand biological knowledge.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure, 1-magnetic sheet, 2-adhesive tape, 3-hemisphere, 4-ellipse, 5-circular slab, the tubular plate of 6-, 7-adhesive tape, 8-oral groove layer, 9-groove.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of biological demonstration teaching aid, it comprises magnetic sheet 1, adhesive tape 7, magnetic fittings and oral groove layer 8, magnetic sheet 1 is provided with groove 9, and oral groove layer 8 is attached on magnetic sheet 1, and adhesive tape 7 is arranged on the surrounding of magnetic sheet 1; Described magnetic fittings comprises hemisphere 3, ellipse 4, circular slab 5 and tubular plate 6, magnetic fittings is adsorbed on magnetic sheet 1, described circular slab 5 quantity is multiple, wherein two circular slabs 5 are wound with tubular plate 6 all around, deserve to be called respectively and state two circular slabs 5 for circular slab A and circular slab B, circular slab A is adsorbed in the top of magnetic sheet 1, and circular slab B is adsorbed in the bottom of magnetic sheet 1.
It also comprises adhesive tape 2, and adhesive tape 2 is attached on magnetic sheet 1.
Magnetic sheet 1 represents the tenuigenin of paramecium, adhesive tape 7 represents paramecium cilium, ellipse 4 represents the macronucleus of paramecium, and hemisphere 3 represents the small nut of paramecium, and circular slab 5 represents food vacuole or expansion bubble, independent circular slab 5 represents food vacuole, the circular slab 5 being wound with tubular plate 6 all around represents expansion bubble, and tubular plate 6 represents the collection tube of paramecium, and groove 9 represents paramecium cytopyge, oral groove layer 8 represents the oral groove of paramecium, and adhesive tape 2 represents the pellicle of paramecium.
During use, only magnetic fittings need be adsorbed on magnetic sheet 1, and with adhesive tape 2, magnetic fittings is fixed on magnetic sheet 1, anabolic process is simple, and the morphosis of paramecium can be shown out intuitively, the manipulative ability that can strengthen student can help again student to understand the morphosis of paramecium.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
