DIY Sun-Moon-Earth Geography Model Scientific Experiment Kits

Description:

The purpose of the utility model is to provide a moon-system motion model.

Can not only objectively reflect the space position of the three celestial bodies, namely the sun, the earth and the moon.

But also demonstrate the operating conditions of the sun, the earth and the moon intuitively and systematically.

As well as various natural phenomena produced by the mutual motion of the three celestial bodies.Knowledge Class:

The principle of Sun Moon Earth model is moving rule between Sun Moon Earth.

The model consists of three small spheres representing the sun, the earth and the moon, and has mechanical linkages to demonstrate the three-balls relationship and astronomical phenomena resulting.

In order to mimic the reality of nature, the central sun usually uses a glowing light bulb to lighten the earth and the moon.

The earth orbited the sun, and the moon orbited the earth at an angle to the earth’s orbit around the sun.

The model can demonstrate solar and lunar eclipses,phases of the moon, the earth’s rotation and revolution, and the alternation of day night and the seasons.
