Novel lunar phase formation exploration instrument

Abstract

The invention relates to a novel lunar phase formation exploration instrument. The novel lunar phase formation exploration instrument comprises a dark box and a flat plate for simulating the revolution plane of the earth and the revolution plane of the moon, wherein a driving device for driving the flat plate to rotate is arranged at the bottom of the dark box, a terrestrial globe device for simulating the earth is arranged in the middle of the flat plate and comprises a camera capable of being connected to a computer, a selenographic globe device which is aligned with the camera and used for simulating the moon is arranged on the flat plate, and a light-emitting device for simulating the sun is arranged on the inner wall of the dark box so that light can irradiate the camera and the selenographic globe device. The novel lunar phase formation exploration instrument further comprises a cover, wherein the top of the dark box can be covered with the cover. The novel lunar phase formation exploration instrument makes teaching visualized and makes phenomenon simulation scientific, vivid and interesting.

Description

【Technical field】 [0001] The invention relates to a novel lunar phase formation probe. 【Background technique】 [0002] When teaching the third lesson "Moon" of the fifth grade primary science volume of Cantonese Education Science and Technology Edition, I found that most of the students were disturbed by the knowledge of the formation of lunar eclipses. Forming. [0003] The textbook arranges experiments in this way to let students understand the phenomenon of moon phase changes: first draw a circle on the ground to represent the orbit of the moon, and then paste a picture of the sun on the wall. A classmate held a half black and half free moon model and moved along the "moon orbit". The white half of the moon should always face the sun pattern when moving. Another student stood in the position of "Earth" and observed. This will have the following disadvantages: [0004] 1. It is only suitable for 2 people to participate, and requires a large space, and requires a place...

AI Technical Summary

Problems solved by technology

[0005] 2. The "sun" is represented by a picture and cannot emit light. The moon is a half-black and half-natural model. When moving, the white half of the moon must always face the pattern of the sun. Why is this so? Most students do not understand

Primary school students are characterized by strong intuitive perceptual knowledge, so after the activity is carried out, most students cannot really understand the reasons for the formation of moon phases

[0006] And other teaching aids are relatively abstract, it is difficult for primary school students to intuitively understand
