Abstract
The utility model relates to a planetarium for teaching, which is composed of a simulated planetarium ball and a control box, wherein, the simulated planetarium ball is a circular hollow ball made of paper of plastic, warps and wefts are marked on the ball surface, and holes with different sizes are utilized to respectively represent constellations, such as the Great Bear, the Little Bear, etc. according to stellar maps, stars, etc. A light source is installed in the ball, a shaft is installed on the ball and can rotate, and a power supply controlling part in the control box is utilized to control the light intensity. If the planetarium for teaching is arranged in a light proof classroom, the positions of constellations and the changing rules of constellations in one day and one year can be demonstrated by means of a teaching leading lamp. The planetarium for teaching has the advantages of convenient star teaching of four seasons and favorable teaching effect.
Description
A kind of teaching planetarium is applicable to the demonstration chronometer phenomenon.
Astronomical teaching accounts for heavier ratio in the primary school nature teaching, but existing astronomical teaching wall chart, teaching aid such as teaching astronomical globe etc. can not show intuitively that all day aerial constellation and constellation thereof are at one day Middle East Sheng Xi chronometer phenomenon such as fall, move westwards gradually in a year, so some chronometer phenomenons are difficult to be accepted by the student.
The purpose of this utility model is at the existing deficiency of instruments used for education in the current primary school astronomical teaching, a kind of teaching planetarium is proposed, this planetarium can be clear, demonstrate out a day aerial constellation and the variation of constellation in one day, 1 year thereof intuitively, gives the student astronomical phenomena impression intuitively.
The utility model is achieved in that with a georama makes simulation astronomical phenomena ball, gets the hole of representing star one by one by stellar map thereon, and the big rootlet in aperture is equipped with axle according to the grade of star on this georama, and is rotatable, in light source is arranged.In covering the classroom of sunlight, connect light source, the aperture of light on georama penetrates, and promptly clearly demonstrates the position and the feature of constellation on the ceiling, with teaching guidance lamp indication explanation chronometer phenomenon.
Below in conjunction with accompanying drawing the utility model is described in further details.
Accompanying drawing is a structural representation of the present utility model.Referring to accompanying drawing, the utility model is made up of simulation astronomical phenomena ball 1 and control enclosure 6.Simulation celestial sphere 1 is the georama that papery or plastics are made, its face is marked with warp and weft, and represent ursa major, Ursa Minor, Pegasus, Cassiopeia (Cas), Altair, women weaver's magnitude constellation respectively with a plurality of holes 5, aperture not of uniform size, grade by star is represented with hole not of uniform size, be that the big star of grade represents that with macropore the star that grade is little is represented with aperture.On the simulation astronomical phenomena ball 1 axle 3 is housed, the other end dress bulb of axle 3 directly extends the center of simulating the astronomical phenomena ball, and the other end of axle 3 is a plug, and simulation astronomical phenomena ball is by the plug end insertion axle sleeve 4 of axle 3, and both fixed-analog astronomical phenomena ball 1 was connected power supply in the ball again; Support 2 is arranged on the control enclosure 6, axle sleeve 4 is housed on the support 2, in the control enclosure 6, power control is housed, power switch 7 is arranged on its panel, the gauge tap 9 of simulation astronomical phenomena ball light source switch 8 and teaching guidance lamp 10.During use, this teaching planetarium is placed in the classroom that hangs with window shade, energized, the light source switch 8 of simulation astronomical phenomena ball 1 is transferred to correct position, rotate simulation astronomical phenomena ball 1, with teaching guidance lamp 10 indication reflect the constellation that shows, just can give a lecture the position feature and the Changing Pattern in a day, a year thereof of each constellation intuitively.Be contained on the used ground month running instrument (having another name called three-globe instrument) and also can demonstrate chronometer phenomenons such as formation, four seasons formation, phases of the moon formation, day, lunar eclipse formation round the clock as simulating the astronomical phenomena ball.Like this, promptly make things convenient for lecture to improve the interest that the student learns astronomic knowledge again, through the hands-on instruction demonstration, effect is splendid.
Claims (1)
- A kind of teaching planetarium of forming by simulation astronomical phenomena ball 1 and control enclosure 6, it is characterized in that: the sphere of simulation astronomical phenomena ball 1 is marked with through, parallel, and represent constellation respectively with hole 5, the end of simulation astronomical phenomena ball 1 by axle 3 is inserted in the axle sleeve 4 on the support 2 of control enclosure 6, the other end of axle 3 is adorned bulb, extends to the ball center of astronomical phenomena ball 1.
