Product Description

Earth-Sun-Moon/Planetarium Model (physics instrument)

Product Introduction
The model of sun-moon-earth is a special teaching instrument that directly reflects the relative motion law between the sun, the earth and the moon. It can vividly simulate the relative positions of the sun, the earth and the moon in the universe, and can vividly show the motion state of the three spheres, and scientifically explain various natural phenomena arising therefrom.

Product Specification
Product name model of sun-moon-earth
Material Plastic
Composition The products are composed of base, sun model, earth model, moon model, four seasons disc, moon phase disc, pointer, rotary component, turntable, push handle, etc.
Size Base diameter φ220mm, sun model φ100mm, earth model φ57mm, moon model φ19mm, four seasons disk φ195mm, moon phase disk φ110mm,

Product feature and application

Demonstration content
Earth's rotation and revolution
The revolution of the moon:
Day and night in the same place:
Day and night at the same time:
Because the earth is always inclined to revolve or rotate, the days in the northern hemisphere are short in winter and the nights are long in summer. The Southern Hemisphere is the opposite.
Four seasons and changes in summer and winter
Changes in the roundness of the moon

Education use for students
For elementary science teaching

Maintenance and precautions
1. Before the demonstration, you should first check that the pointer is facing the summer solstice, and the axis of the earth is
No pointing to the sun. If it is not aligned, you need to loosen the pinion fixing nut under the moon phase plate, and then tighten it after alignment.
2. When demonstrating the operation, the rotating handle should be pushed counterclockwise to rotate, so as to conform to the law of celestial movement. The running speed should not be too fast, and the impact force or high-speed rotation should not be used by all means, otherwise it will affect the life of the instrument and even damage it quickly.
3. When holding the instrument, hold the neck of the base plate with your hand, and keep the instrument upright to prevent the sun ball from falling off its shaft sleeve and being damaged.
4. The veneer of the earth model, the four seasons disc and the moon phase disc of the instrument are all paper, so they cannot be washed with water directly. If there is any stain, it can be wiped with a soft cloth wrung out after washing.
5. The instrument is made of plastic and cannot be dropped or weighed down.
6. After the instrument has been used for a long time, it may be difficult to rotate due to the drying of the lubricating oil. At this time, an appropriate amount of lubricating oil can be added to the relevant parts of the instrument to reduce the resistance.
7. After the instrument is used, it should be placed in a cool and dry place, and the instrument cannot be inverted.
