In order to guide young people to strengthen their sense of identity and honor of China's traditional culture, strengthen cultural confidence and patriotism, Mr. Sun Kai, secretary of the Party Branch of Marine Materials Graduate students, was invited to the classroom of Class 4 (1) of Mingzhu Lingang Primary School, Pudong New District, Shanghai, to bring a cultural feast and scientific baptism to the children with the theme of China's 'wisdom' made, 'cast' on the legend.
Casting technology is an ancient and new technology, which inherits the splendid Chinese civilization and guards the long historical context. Mr. Sun combined his professional knowledge and teaching content, taking the treasure of the town hall of Shanghai Museum - Dake Ding as the starting point, focusing on the use of the tripod evolution, symbolic meaning, production process and other content, combined with the Central Plains, The Three Kingdoms, one word and nine tripod, the voice of the people and the strength of the tripod and other historical alludes and idioms. The students' cultural influence and scientific vision are enhanced by the way of edutainment. He focused on the scientific principles and process of bronze casting by block method and lost wax method, combined with video animation, transformed obscure scientific knowledge into easy to understand learning content through vivid and interesting cases, and led the children to review the long history and long history of foundry technology in China. After class, he had cordial exchanges and heated discussions with the children. The children not only learned that casting technology can produce ancient bronze ware such as bell tripods and jade plates, but also can produce advanced industrial equipment such as automobile engines, aircraft turbine blades, and ship propellers, but also learned that the investment casting technology in the United States is also derived from the traditional casting technology of China's lost wax method.
Through this activity, it further plays the leading role of party construction and the function of science popularization and education, builds a bridge of communication between universities and primary schools, and broadens the scientific vision and innovative thinking of young people, strengthens patriotic feelings, and cultivates new people of The Times.
