Description
Technical field
The present invention relates to a kind of teaching aid, particularly relate to a kind of geography teaching appliance of demonstrating revolution of earth.
Background technology
In middle and primary schools' geography course teaching, when explanation the revolution of earth knowledge point, often carry out simple demonstration explanation by existing terrestrial globe, but only utilize the existing teaching aids such as terrestrial globe, be difficult to demonstration explanation subsolar point along with revolution of earth movement law at the earth's surface.Chinese patent CN200910305290.X discloses a kind of earth revolution method and terrestrial globe thereof, comprise: globe base, terrestrial globe, lamp base, sunlamp, on globe base and lamp base, there is respectively sheave and focus sheave, between sheave, there is looped cord to connect, sunlamp is positioned on a focus sheave above lamp base, and on the ecliptic plane that is centered close to revolution of earth of sunlamp, this patent is shown the analogue means of revolution of earth, process and the origin cause of formation of earth Four seasons change are annotated, but its structure is comparatively complicated, and utilize looped cord to be connected between terrestrial globe and sunlamp, and the invisible universal gravitation between the objective middle sun and the earth contacts inconsistent, easily mislead students, particularly lower student.
In teaching, particularly geography teaching in middle school, subsolar point is along with the mobile Changing Pattern of revolution of earth is comparatively abstract, and student is difficult for understanding, and is a difficult point of geographical teaching, and by teaching aids such as existing terrestrial globes, it is clear that teacher is difficult to demonstrate explanation to student.
Summary of the invention
The object of the invention is to solve in geographical teaching, utilize the teaching aids such as existing terrestrial globe, be difficult to the problem of the revolution phenomenon of the objective reality demonstration earth, provide a kind of simple in structure, demonstration is convenient, can intuitively show the geography teaching appliance of revolution of earth phenomenon and subsolar point movement law.
The present invention realizes by following measures: earth revolution-demonstrating instrument of the present invention, mainly comprise ecliptic panel, ecliptic, stationary shaft, sun spheroid, light supply apparatus, terrestrial globe, metal gravity ball and level meter, it is characterized in that: ecliptic panel is designed with rotund ecliptic, under ecliptic, be furnished with magnet, middle part at ecliptic is fixed wtih stationary shaft, on stationary shaft, be fixed wtih sun spheroid, sun spheroid can rotate around stationary shaft, in sun spheroid, has light supply apparatus.
Wherein inner side, the Antarctic Circle of terrestrial globe is provided with a circle pipeline, has a metal gravity ball in pipeline.
Wherein in sun spheroid, have light supply apparatus, it sends the ray light source that light source is optically focused point-like, and the centre of sphere height of its light source height and terrestrial globe is consistent.
Wherein ecliptic panel is furnished with a level meter.
In teaching, by earth revolution-demonstrating instrument demonstration of the present invention, detect horizontal positioned ecliptic panel by level meter.Terrestrial globe is placed on ecliptic and is rolled, because the inner side, the Antarctic Circle of terrestrial globe is provided with a circle pipeline, in pipeline, there is a metal gravity ball, on ecliptic, be furnished with magnet, the earth will be placed on ecliptic panel obliquely, the equatorial plane of terrestrial globe and ecliptic panel are keeping 66 ° of 34 ' angles, and terrestrial globe is rotated around sun spheroid on ecliptic, can demonstrate intuitively and accurately the revolution phenomenon of the earth.Open the light supply apparatus in sun spheroid, the light source point of its ejaculation is consistent with terrestrial globe centre of sphere height, when the sensing of arctic point is fixed, along with the revolution of terrestrial globe, rotate sun spheroid, the light source point of its ejaculation is dropped on globe surface, and light source point will move between the north and south tropic at terrestrial globe, gets final product the movement law of subsolar point on the ocular demonstration earth.
The invention solves the geography teaching appliances such as common terrestrial globe and be difficult to true demonstration revolution of earth phenomenon directly perceived and subsolar point mobile phenomenon at the earth's surface, it is simple in structure, teaching demonstration is easy to operate, is easy to the knowledge of the movement law of subsolar point on student's understand and master revolution of earth and the earth.
Brief description of the drawings
Fig. 1 is the structural representation of earth revolution-demonstrating instrument of the present invention.
embodiment:
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, earth revolution-demonstrating instrument of the present invention, mainly comprise ecliptic panel 1, ecliptic 2, stationary shaft 4, sun spheroid 3, light supply apparatus 6, terrestrial globe 5, metal gravity ball 7 and level meter 8, ecliptic panel 1 is designed with a level meter 8 and circular ecliptic 2, ecliptic is furnished with magnet 2 times, be fixed wtih stationary shaft 4 at the middle part of ecliptic 2, on stationary shaft 4, be fixed wtih sun spheroid 3, sun spheroid 3 can rotate around stationary shaft 4, in sun spheroid 3, there is light supply apparatus 6, it sends the ray light source that light source is optically focused point-like, the centre of sphere height of the height of light source and terrestrial globe 5 is consistent.
Wherein inner side, the Antarctic Circle of terrestrial globe 5 is provided with a circle pipeline, has a metal gravity ball 7 in pipeline.
When earth revolution-demonstrating instrument of the present invention uses, ecliptic panel 1 horizontal positioned, terrestrial globe 5 rotates around sun spheroid 3 obliquely on ecliptic 2, has demonstrated the revolution phenomenon of the earth; Along with the revolution of terrestrial globe 5, rotate sun spheroid 3, the light source point of its ejaculation will move between the north and south tropic at terrestrial globe 5, has demonstrated the movement law of subsolar point on the earth.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit; those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute, and also drop on the scope of the present invention.
