Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and detailed description, and it is to be understood that the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
In order to dynamically, vividly and intuitively display the lunar phase cause, the embodiment provides a lunar phase cause demonstration instrument for teaching shown in fig. 1, which comprises an earth simulation globe 3, a lunar simulation globe 2 and a sun simulation illuminating lamp 4; the lunar simulation ball 2 is placed on the lunar revolution simulation orbit 1, at least four lunar simulation ball 2 placing grooves 5 simulating east, south, west and north directions are arranged on the lunar revolution simulation orbit 1, lunar phase change caused by lunar position change can be observed by means of the four lunar simulation ball placing grooves 5 simulating different directions, the lunar simulation ball is visual and vivid, the operation is simple, only one lunar simulation ball such as a leather ball or a ping-pong ball is required to be placed in each direction, and the condition that the lunar at different positions is illuminated can be observed only by changing the placing position of one lunar simulation ball (changing the position of a lunar simulator is really the lunar phase change during lunar revolution).
The earth simulation ball 3 is placed at the central position of the moon revolution simulation orbit 1; the sun simulation illuminating lamp 4 is hung obliquely above the outer side of the moon revolution simulation orbit 1 through a rope. The earth can be simulated by the rubber ball with larger volume, so that the illumination incident on the moon simulation ball can be influenced, and the change of the illumination caused by the influence of the earth on the moon at different positions can be obviously observed.
In order to further demonstrate the influence of the revolution of the earth on the illumination of the moon or the lunar phase, the present embodiment places the earth-simulated globe 3 on an earth orbit simulation circular orbit 6 shown in fig. 2; the earth orbit simulation annular orbit 6 is also provided with at least four limiting grooves 7 for simulating east, south, west and north directions and placing the earth simulation balls 3; two sides of the limit groove 7 are respectively provided with a clamping groove 8 which is arranged on the earth orbit simulation circular orbit 6 and is used for clamping the lunar revolution simulation orbit 1, so that the whole system shown in figure 1 is completely arranged on the earth orbit simulation circular orbit 6, and then the illumination change, namely the lunar phase change, generated by the lunar revolution on the lunar simulation ball is observed by changing the position of the whole system shown in figure 1 on the earth orbit simulation circular orbit 6.
In order to facilitate the fixation, in the embodiment, the fixing seat 9 is arranged on the bottom surface of the earth orbit simulation annular orbit 6 below the limiting groove 7, and the fixing seat can be formed by matching a disc base with a supporting rod or just a cylindrical seat cushion.
The moon which does not emit light can be vividly demonstrated by the demonstration device, and the side facing the sun (illuminating lamp) is bright and the side facing away from the sun is dark. During the revolution of the moon, the surface facing the earth is sometimes entirely bright, and sometimes the bright portion is larger than the dark portion, and sometimes the bright portion and the dark portion are half each other. Sometimes the bright parts are smaller than the dark parts, sometimes all dark. Thus, a change in the lunar phase is observed on the earth.
