Abstract

The invention discloses a solar eclipse and lunar phase teaching demonstrator, which comprises a box body, an LED spherical lamp and a blocking ball, wherein a track is arranged on a bottom plate in the box body, and the blocking ball can slide in the track; the LED spherical lamp is fixedly arranged on the bottom plate of the box body, and the track in the box body is divided into a straight track and a circular arc track. The solar eclipse and lunar phase teaching demonstrator provided by the invention has a simple structure and can clearly demonstrate astronomical phenomena such as solar eclipses and lunar phases, and the demonstration process is closer to the real solar eclipses phenomenon process, so that an observer can quickly understand the generation principle of solar eclipses. The solar eclipse and lunar phase demonstrator provided by the invention can also intuitively show the astronomical phenomena such as total solar eclipse and annular solar eclipse caused by the difference in the distance between the moon and the earth.

Description

technical field [0001] The invention belongs to the technical field of stationery, in particular to a solar eclipse and moon phase teaching demonstration instrument. Background technique [0002] In the stage of primary and secondary education, astronomical phenomena such as solar eclipse and moon are often too abstract for students to understand because there are no real objects. Therefore, the teaching demonstration device that can show the generation process of solar eclipse and moon phase is helpful for primary and secondary school students to quickly understand the learning content. huge. [0003] Existing solar and lunar eclipse demonstration devices often use spheres of different sizes to represent the sun, moon and earth, and the spheres move on concentric arcs to simulate astronomical phenomena such as solar eclipses. Different astronomical phenomena such as total eclipse and annular solar eclipse are caused by the difference in the distance between the moon and th...
