Introduction of winter solstice activities in kindergartens

The contents of the briefing session on winter solstice activities in kindergartens are as follows:

First of all, a brief introduction.

1, winter solstice, also known as solstice, winter festival, sub-year, etc. It has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year.

2. The custom of winter solstice is different in content or detail due to different regions. In southern China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.

Second, the specific situation

1, the winter solstice is the 22nd solar term in the "24 solar terms", and the longitude of the sun reaches 270, which is an annual festival on the Gregorian calendar 65438+February 2 1-23. The solstice in winter is the extreme point of direct sunlight spreading to the south. On the solstice in winter, the sun shines directly on the Tropic of Capricorn, which is the most inclined to the northern hemisphere and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

2. The winter solstice, that is, the turning point of direct sunlight returning to the north. After this day, I went back, and the point of direct sunlight began to move northward from the Tropic of Capricorn (23 26' s), and the daytime in the northern hemisphere (China is located in the northern hemisphere) increased day by day. In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology.

In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice. Because of the great difference in climate in different parts of China, this winter climate is obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.

Third, phenology.

1. In some ancient Chinese literary works, the winter solstice is divided into three stages: "One is earthworm knot; Second, wait for the elk horn to solve; Waiting for the spring to gush out. " It means that the earthworm is still curled up in the soil, and the elk feels the yin gradually retreating and falling off its horns.

2. As the direct point of the sun returns to the north from winter to the future, the sun moves back and forth into a new cycle, the height of the sun rises from now on, and the days become longer day by day, so the spring water in the mountain can flow and be warm as spring.
