In order to thoroughly implement the requirements of the "Action Plan for National Science Literacy (2021-2035)" and the newly revised "Law of the People's Republic of China on Science and Technology Popularization", fully leverage the advantages of scientific research and popularization resources in universities, stimulate the exploration enthusiasm of primary and secondary school students for earth science, and enhance the scientific literacy of young people, from May 30th to 31st, the National Key Laboratory of Continental Evolution and Early Life and the Department of Geology of Northwest University successfully held two "Stone Code" themed science popularization practical activities to explore the earth at the Taibai Campus and Chang'an Campus of the school. Nearly 50 primary school students actively participated and immersed themselves in unlocking the mysteries of earth rocks.

The event site is full of practical knowledge and has a strong atmosphere. Science popularization volunteer Yang Yunpeng (a master's student in the Department of Geology at Northwest University) led children to approach the "hard core code" of the Earth - rocks - in vivid and popular language. Based on rock science knowledge, systematically explain the core characteristics, formation principles, and unique features of three major types of rocks: magmatic rocks, sedimentary rocks, and metamorphic rocks, and meticulously dissect the identification techniques for different rocks. At the same time, through dynamic and easy to understand knowledge explanations, the geological processes of the transformation of the three major rock types are popularized, transforming abstract earth science knowledge into intuitive and interesting content. In class, children listen attentively, think seriously, and immerse themselves in the unique charm of geological science.

Activity setting: rock practical identification section. Children apply what they learn, relying on the identification methods learned in lectures, carefully observe the texture, texture, color and other characteristics of rocks, and independently complete rock recognition and classification tasks. The on-site participation atmosphere was enthusiastic, and the children actively engaged in hands-on activities and boldly explored, successfully completing practical challenges with excellent observation and learning abilities.

This science popularization practice activity, in the form of fun science popularization and practical experience, not only allows children to explore the mysteries of Earth's rocks up close and gain professional geological knowledge, but also plants the seeds of love for science and courage to explore in their hearts.
