Abstract
The utility model relates to a moon phase change demonstration instrument comprising parts of a pedestal, a moon phase disc, a fixed connecting rod, a flexible connecting rod, a tellurion, a tellurion black half cover, a glass lens, a selenographic globe, etc. The flexible connecting rod is connected with the fixed connecting rod via left, intermediate and right crank shafts which are completely identical in shape. The tellurion and the tellurion black half cover are bound on the top end of the intermediate crank shaft. The tellurion can freely rotate in the tellurion black half cover. The middle part of the tellurion black half cover is adhered with the glass lens. The moon phase disc is worn on the intermediate crank shaft and arranged between the flexible connecting rod and the tellurion. The selenographic globe is arranged on the top end of the left crank shaft. The glass lens imaging principle is utilized, and the glass lens is applied to simulate human eyes so that moon phase change that cannot be observed on a common tellurion can visually and continuously appear in the glass lens. Therefore, observation interest of students can be stimulated, space imagination of the students is cultivated and curriculum teaching effect is greatly enhanced.
Description
Technical field
The utility model relates to teaching aid technical field, is specifically related to a kind of phases of the moon change modeling teaching aid.
Background technology
The variation of the phases of the moon and the phases of the moon is one of content of courses of school science class.On the one hand, this partial content observation cycle is long, and student is difficult for adhering to for a long time; On the other hand, student lacks space imagination, be difficult to the moon appearance of seeing to be converted into the lunar chiaroscuro of seeing in textbook, i.e. thinking lacks the bridge of construction between the real moon and the lunar chiaroscuro of plane, so brought very large difficulty to student's understanding and study.For making up this defect, now developed many simulation teaching aids about moon phase change, some teaching aids remain plane, can only demonstrate the change procedure of lunar chiaroscuro; What have cuts terrestrial globe open, loads onto glass mirror inside, then from mirror, observes the phases of the moon, does not conform to like this principles of science.
Summary of the invention
The defect existing for above-mentioned prior art, technical problem to be solved in the utility model be to provide a kind of simplicity of design, easy to make, can be directly perceived from glass mirror, Continuous Observation is to the moon phase transformation demonstration instrument of moon phase change.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of moon phase transformation demonstration instrument, comprise the parts such as base 1, moon dial 2, stationary links 3, movable rod 4, terrestrial globe 5, terrestrial globe blackly partly cover 6, glass mirror 7, lunar globe 8, wherein, stationary links 3 is fixedly mounted with and is connected with base 1.Movable rod 4 is connected with stationary links 3 by three of the left, center, right identical bent axle 9 of shape, at the top binding terrestrial globe 5 of middle bent axle 9 and terrestrial globe is black partly covers 6, terrestrial globe 5 can partly cover 6 and interiorly freely rotate terrestrial globe is black, at black 6 the middle part sticking glass eyeglass 7 that partly covers of terrestrial globe, moon dial 2 is through on middle bent axle 9, and between movable rod 4 and terrestrial globe 5, on the top of left hand crankshaft 9, load onto lunar globe 8.
The utility model is used glass mirror image-forming principle, eyes with glass mirror simulation people, make cannot to observe on common terrestrial globe the moon phase change can be in glass mirror intuitively, occur continuously, can excite student's observation interest like this, the Space Imagination power of cultivating student, has improved Teaching Effect greatly.
Accompanying drawing explanation
Fig. 1 is the utility model main assembly schematic diagram.
Fig. 2 is the utility model stationary links, movable rod and bent axle assembling relationship figure.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Fig. 1～2, moon phase transformation demonstration instrument comprises the parts such as base 1, moon dial 2, stationary links 3, movable rod 4, terrestrial globe 5, terrestrial globe blackly partly cover 6, glass mirror 7, lunar globe 8, and wherein, stationary links 3 is fixedly mounted with and is connected with base 1.
Half of getting a ball more slightly larger than terrestrial globe makes that terrestrial globe is black partly covers 6, and black half cover represents night, at the middle part of black half cover, with glue, is stained with 8 little glass mirror 7, and eyeglass represents the eye of people on the earth.Terrestrial globe is placed in black half cover, and terrestrial globe can freely rotate in cover, and the part that terrestrial globe is not covered represents daytime.Half painted black of table tennis is made to lunar globe 8, and lunar globe black part is divided and is represented to carry the sun, and white represents the part being illuminated by sunshine, and during installation, the black and white part orientation of terrestrial globe and lunar globe wants consistent.
Get two battens that are about 40cm and make stationary links and movable rod, in three of the left, center, right of connecting rod, part is bored three apertures, with three iron wires, be bent into three bent axles that shape is identical, three bent axles are placed in respectively in three apertures, at the top of middle bent axle binding terrestrial globe and black half cover of terrestrial globe, on the top of left hand crankshaft, load onto lunar globe.A three-ply board is sawn into disk, pastes lunar chiaroscuro on it, make moon dial 2, moon dial is through on middle bent axle 9, and between movable rod 4 and terrestrial globe 5, last, said apparatus is fixed on base 1.
Two hold the two ends of stationary links, promote movable rod, make black half cover of terrestrial globe and lunar globe simultaneously by counterclockwise rotating (that is, make the earth rotates from west to east moves), only rotate 45 at every turn
0.Black half cover of terrestrial globe often turns 45
0just with hand, stir moon dial, make its clockwise direction move to next month phasor position.The lunar map of seeing from glass mirror is as the image of front-month phase change.
Keep terrestrial globe and lunar globe white portion all the time towards a direction, i.e. the invariant position of the sun, the earth is around solar motion.Namely, when promoting movable rod, black half cover of terrestrial globe also rotates, and terrestrial globe white portion is pointed to while changing, and whole device is moved back into together with base to the direction of terrestrial globe white portion indication.
In the ken that the utility model possesses at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make various variations.
