Apparatus for demonstrating solar eclipse phenomenon

Abstract

The invention provides an apparatus for demonstrating a solar eclipse phenomenon creatively. The apparatus comprises a pedestal, a rack body, and a terrestrial globe. The rack body includes a support frame, a circular horizontal track arranged on the support frame around the terrestrial globe, and a semicircular vertical track arranged on the support frame around the terrestrial globe. The terrestrial globe is arranged at the center of circle of the vertical track. An observation rod is arranged on the top of the terrestrial globe vertically. A first light-emitting source is arranged on the horizontal track; and a second light-emitting source is arranged on the vertical track. The plane where the vertical track is located is perpendicular to the plane where the horizontal track is located; and the two ends of the vertical track correspond to the two ends of the diameter of the horizontal track. The demonstration apparatus has advantages of simple structure, low manufacturing cost, easy test operation, good time saving effect, high efficiency, and visual test structure. Several kinds of tests are realized by using one apparatus; the lesson giving efficiency is high; an effect of teaching with joyful activities is realized; the cognitive level of the student is improved; the learning interest of the student is aroused; and thus students can master the knowledge of the solar eclipse phenomenon better.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and in particular relates to a solar phenomenon demonstration device. Background technique [0002] Solar radiation is the most important driving force that determines changes in the earth's atmosphere, water, and life activities. It is the basic energy source for human survival and development, and it is closely related to human beings. When learning the principles of solar eclipse formation, students cannot intuitively understand the occurrence of solar eclipse phenomena only through textbook knowledge and teacher's explanations, so it is difficult for students to understand. Geography is a very abstract subject. Give full play to the students' spatial imagination ability, so if the teacher does not have auxiliary teaching equipment in class, it is difficult to describe it, and it is difficult to explain it to students, and it is also difficult for students to understand. Solar eclipse is...

When learning the principle of solar eclipse formation, only through textbook knowledge and teacher's explanation, students cannot intuitively understand the occurrence of solar eclipse phenomenon, so it is difficult for students to understand. Geography is a very abstract subject. Give full play to the students' spatial imagination ability, so if there is no auxiliary teaching equipment when the teacher is in class, it is difficult to describe it, and it is difficult to explain it to the students, and it is also difficult for the students to understand. Therefore, in order to be more vivid and better for students to absorb and understand, it is urgent to design a teaching aid that can easily demonstrate solar phenomena
