Abstract

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

A kind of phases of the moon teaching mode

Technical field

The present invention relates to a kind of uranology model, specifically, be the model that a kind of people of help understand moon phase cause.

Background technology

At present, China's course is " phases of the moon " content of courses as Science Curriculum, the science popularization venue also with " phases of the moon " as a science popularization contentIn teaching or science popularization venue, represent the phases of the moon mainly with planar graph or " three-globe instrument " teaching mode, both be difficult to bring the observer into simulated scenario, reproduce intuitively phases of the moon variation phenomenon, people (particularly student) are difficult to observe phases of the moon change procedure, also form reason with regard to the indigestion phases of the moon.

Summary of the invention

Technical matters to be solved by this invention is to provide the visual simulation of a kind of energy to reproduce the model of phases of the moon change procedure and phenomenon.

For addressing the above problem, technical scheme of the present invention is: a kind of phases of the moon teaching mode comprises the spheroid of a simulation earth, the spheroid of a simulation moon, simulated solar and spheroid that can be luminous.The spheroid of the simulation earth can cover on observer's head and have viewport can allow the observer see outside scenery, or the observer can invest model surface, and the observer can rotate with earth model; The spheroid of the simulation moon is opaque, can move around earth model; But the relative transfixion of the photosphere of simulated solar, and comprise and to control its luminous power supply, switch, light-emitting component etc.Three spheroid sizes, far and near and known size, far and near ratio are relative consistent, and movement velocity and the known earth, moon motion speed proportional are relative consistent.

Compared with prior art, the invention has the beneficial effects as follows: the present invention is consistent with the earth, the moon, sun three's size, distance, movement velocity ratio, can demonstrate three's kinematic relation, the observer can be placed in scene and observe intuitively position relationship between phases of the moon change procedure and three spheroids, thereby understand phases of the moon change procedure and various moon phase cause.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

In figure, 1, solar model, 2, moon model, 3, earth model, 4, power switch, 5, power lead, 6, light-emitting component, 7, viewport, 8, light.

Embodiment

OpenThe model sun (1) power switch (4) by power lead (5) conduction, makes light-emitting component (6) luminous, is subjected to the light situation when observer observes the model moon (2) motion by the model earth (3), reproduce with the true phases of the moon one to the variation sight.After the observer had observed a simulation cycle, the exit model earth aside continued three movement of heavenly bodies situations are observed, and understood the position relationship of three celestial bodies when forming the various phases of the moon, thereby understood phases of the moon change procedure and various phases of the moon formation reason.

Claims

1. The present invention relates to a kind of phases of the moon teaching modeThe earth model that the observer can be placed in one, intuitively observe phases of the moon change procedure, leave earth model, can be observed the position relationship in the earth, the moon, three model sport change procedures of the sun, and the size of three models, far and near ratio, movement velocity ratio are consistent with known ratio data.
