Abstract

The patent of the invention relates to a teaching instrument, in particular to a novel lunar origin demonstrator which solves the problem of no visual and visual teaching aids demonstration moon phasecauses and the original projector waste resources re-use; the instrument comprises a box body, a control switch arranged on the box body, a power socket, a heat dissipation fan arranged inside the box body, a reflecting bowl, a 300W bromine-tungsten lamp and a transformer; the original projector screw condenser can obtain parallel light by lowering the height of the condenser; heat insulation with thick glass liner under it; a movable plane mirror is arranged above the movable bracket, and the movable bracket is used for fixing the movable bracket, so that the strong light is reflected to theearth-moon model; a folding cover plate is hinged on the right side of the box body; a ground-moon model turntable is arranged on the cover plate, and is driven by a small decelerating motor on the back; and a convex lens and a small plane mirror are arranged in the space of the earth model, so that the moon phase can be imaged on the round ground glass; a video head is arranged above the groundglass, and the computer multimedia is connected with the data line, and the lifting knob is adjusted, so that the panorama of the earth-moon model or the close-up of the moon phase can be projected onthe screen.

Description

technical field [0001] The patent of the present invention relates to a teaching instrument, in particular to a new moon phase cause demonstration instrument. Background technique [0002] The knowledge of the causes of moon phases is learned from elementary school to middle school to university, but the existing teaching equipment cannot vividly display the mystery of the causes of moon phases; it makes students, especially primary and middle school students, vague about the knowledge they have learned; education The point of view of science and psychology tells us that "children's thinking is mainly based on direct image thinking"; only when they first obtain perceptual knowledge can they sublimate to rational knowledge. In order to make students have clear and rational understanding, it is urgent to have a very vivid monthly Phasogenic instruments. [0003] With the widespread use of computer multimedia, all the original projectors in schools across the country have beco...
