Problems solved by technology

The former is too abstract to demonstrate the formation of the moon phase, let alone simulate the changing process of the moon phase. During the operation, it is necessary to artificially adjust the day and night hemispheres, which lacks scientific nature, and even with explanations, it is difficult for students to accept

Abstract

The invention relates to the field of astronomical teaching devices, and discloses a moon phase observer. The moon phase observer comprises a globe and a moon model revolving around the globe; the moon model comprises a first sphere and a second sphere; the interior of the first sphere is a cavity, and a side wall of the first sphere is a transparent material; the second sphere is disposed in a cavity inside the first sphere; a magnet is embedded in the second sphere; outer surfaces of left and right hemispheres of the second sphere have two color layers; and the moon model can horizontally rotate within the cavity. The invention utilizes black and white plastic balls to represent the moon. During the revolution, the internal magnet is rotated under the action of the earth's magnetic field, so that the day and night hemispheres of the moon always maintain in the east-west direction, which can simulate the revolution of the moon realistically; the revolution of the moon is observed, thechange process of the moon phase can visually and visually saw; the moon phase diagram can be drawn on the moon phase plate to facilitate the students to understand and master the law of the moon phase change; and the second sphere and the first sphere have multiple cooperation modes.

Description

technical field [0001] The invention relates to the field of astronomical moon phase teaching devices, in particular to a moon phase observer. Background technique [0002] At present, there are two main models for moon phase teaching: one is the two-dimensional model in textbooks; the other is a simple three-dimensional model composed of a small base and black and white plastic balls. The former is too abstract to demonstrate the formation of the moon phase, let alone simulate the change process of the moon phase. During the operation, it is necessary to artificially adjust the day and night hemispheres, which lacks scientific nature, and even with explanations, it is difficult for students to accept it. [0003] This demonstrator is a three-dimensional model. On the one hand, it can clearly display the various phases of the moon, and more significantly, it can clearly present the changing process of the moon phases during the simulation of the moon's revolution.
