Moon phase instrument

Abstract

The invention discloses a moon phase instrument which includes a moon upper semi-sphere, a moon lower semi-sphere cooperatively connected to the moon upper semi-sphere, a shading plate, a hollow main shaft rotational connection with the shading plate, a hollow handle sleeving the hollow main shaft, a base, a conductive slip ring and a scale rotating disk. The conductive slip ring and the scale rotating disk are cooperatively connected with the hollow main shaft, and the conductive slip ring, the scale rotating disk and the hollow main shaft rotate coaxially. The scale rotating disk is built in the base. One surface of the shading plate is provided with a luminescence apparatus, and the other surface is provided with a power supply apparatus electrically connected to the luminescence apparatus. Chinese calendar dates and moon phase names are engraved on the scale rotating disk. A direction-adjustable bearing is arranged at a middle recess cooperative position on the lower surface of the scale rotating disk. The moon phase instrument reasonably simulates the change of the moon phase through the irradiation of an LED light source. The moon landform feature at corresponding moon phase can be seen clearly. The moon phase instrument enables students to scientifically understand moon phase variation rules, and improves the learning enthusiasm of the students.

Description

technical field [0001] The invention relates to the technical field of scientific teaching appliances, in particular to the teaching demonstration of the law of lunar phase changes. Background technique [0002] The Moon is a non-luminous and opaque sphere that orbits the Earth. Therefore, under the irradiation of sunlight, the illuminated half of the moon faces the earth at different angles, and different moon phases will appear; the moon phases are new moon, Emei moon, first quarter moon, waxing gibbous moon, and full moon. . In the current teaching of moon phases in middle schools, graphics are generally used to explain the law of moon phase changes; there are also simple instruments for demonstrating moon phases, which consist of a hemisphere painted black and a hemisphere painted white; during the demonstration, the first 1. It is impossible to objectively show the topography of the moon's surface; second, when demonstrating the changes of the moon phase, the black an...

In the current teaching of moon phases in middle schools, graphics are generally used to explain the law of moon phase changes; there are also simple instruments for demonstrating moon phases, which consist of a hemisphere painted black and a hemisphere painted white; during the demonstration, the first 1. It is impossible to objectively show the topography of the moon's surface; second, when demonstrating the changes of the moon phase, the black and white hemispheres are rotated to simulate; Seeing one side of the moon is different; in fact, the moon always faces the same side as it orbits the earth, and humans on earth can only see one side of the moon
