Problems solved by technology
In teaching or science popularization venues, the moon phases are mostly displayed with flat graphics or "three-ball instrument" teaching models, both of which are difficult to bring observers into the simulated scene and intuitively reproduce the phenomenon of moon phase changes, and it is difficult for people (especially students) Observing the changing process of the moon phases makes it difficult to understand the reasons for the formation of the moon phases

Embodiment Construction
[0008] Open The model sun (1) power switch (4) conducts through the power line (5), so that the light-emitting element (6) emits light, and the observer observes the light received by the model moon (2) through the model earth (3), which is reproduced and real The changing scenarios of the lunar phases. After observing a simulation cycle, the observer exits the model earth and continues to observe the movement of the three celestial bodies to understand the positional relationship of the three celestial bodies when various moon phases are formed, so as to understand the change process of the moon phase and various moon phases. cause of phase formation.

The invention discloses a lunar phase teaching model. The lunar phase teaching model comprises a sphere simulating the globe, a sphere simulating the moon, and a sphere simulating the sun and being capable of emitting lights, wherein the sphere simulating the globe can be hooded on a head of an observer, and is provided with an observation hole to enable the observer to see scene outside; or the observer can be attached to the surface of the model, and can rotate along with the rotation of the globe model; the sphere simulating the moon is non-transparent and is capable of moving around the globe model; and the light-emitting sphere simulating the sun stands still relatively, and includes a power source for controlling the sphere to emit lights, a switch, a light-emitting element and the like. The size and the distance of the three spheres are relatively consistent with the known size and distance proportion; and the movement speeds of the three spheres are relatively consistent with the known movement speed proportion of the globe and the moon. As the size, the distance and the movement speed proportion of the globe, the moon and the sun are consistent, a movement relationship of the globe, the moon and the sun can be demonstrated, the observer can be put in the scene to intuitively observe the lunar phase change process and the position relationship among the three spheres so as to understand the lunar phase change process and the causes of formation of various lunar phases.
Description
technical field [0001] The invention relates to an astronomical model, in particular, a model that helps people understand the causes of lunar phases. Background technique [0002] At present, Chinese courses use "moon phase" as a teaching content of science courses, and science popularization venues also use "moon phase" as a popular science content. In teaching or science popularization venues, the moon phases are mostly displayed with flat graphics or "three-ball instrument" teaching models, both of which are difficult to bring observers into the simulated scene and intuitively reproduce the phenomenon of moon phase changes, and it is difficult for people (especially students) Observing the changing process of the moon phases makes it difficult to understand the reasons for the formation of the moon phases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a model that can intuitively simulate and reproduce the...
