Abstract

Disclosed is a teaching aid capable of displaying how the Winter Solstice and the Summer Solstice are generated when the earth rotates around the sun. The teaching aid is characterized by mainly comprising a display plate, an earth rotation indication plate and a rotating shaft. The upper edge and the lower edge of the display plate are respectively marked with solar electric field cathode marking lines, and the central portion of the display plate is marked with a solar mark, a solar electric field anode marking line, a Summer Solstice mark and a Winter Solstice mark. The earth rotation indication plate is marked with the Tropic of Cancer and the Tropic of Capricorn. By taking the measures provided by the invention, the principle of how the Winter Solstice and the Summer Solstice are generated when the earth rotates around the sun can be visually displayed.

Description

1. Technical field, [0001] The invention belongs to the field of educational science and technology, and in particular relates to the design and manufacture of a teaching aid capable of showing that the earth moves with the sun to produce winter solstice and summer solstice. 2. Background technology [0002] The summer solstice is the earliest determined solar term in the 24 solar terms of the lunar calendar. It is also an important traditional festival in China, known as the "Summer Solstice Festival". Supplementary food" folk proverb.
