"Too rich, too interesting, did not expect to be able to personally make button batteries.。"I made my own tech ice cream, please eat.。"Children from all over the country said excitedly。On May 25, on the occasion of the eighth "National Science and Technology Workers' Day", the Science and Technology Association of Beijing Institute of Technology and the School of Materials jointly held the "Into Materials" public science Day activity at the Zhongguancun Campus, which attracted more than 400 science and technology enthusiasts from all walks of life to participate。

The School of Materials has opened a number of national and provincial key laboratories, public experimental platforms and other laboratories, and the public can enter the magical world of materials together, explore the mystery of materials at close range, and appreciate the elegance of science and technology by participating in a well-designed science exhibition and experimental activities。This activity includes three sections: "New Materials Classroom - Magic Materials design Workshop", "Creative Materials Laboratory - Interesting material world" and "Success Time Machine - Time Travel through the School History Museum"。By participating in more than 20 carefully designed scientific principle demonstrations, science innovation experiments, school history experience and other activities, everyone can feel the unique charm of cutting-edge science and innovative technology represented by materials science up close。

In the "new material classroom" section，Participants create super "Jellies" that do everything by themselves，Understand the miraculous phenomenon of reversible morphological changes of hydrogels in response to the external environment，By taking a closer look at the colorful nano-gold，Feel the coating process of protein and other macromolecules adsorbed on the surface of gold nanoparticles，Fascinated by the magical changes of new materials。In the "creative materials Lab" section，Participants experienced a series of popular science experiments and interactive teaching，In the "using laser to explore the microscopic world", "material universe self-healing superhero - magic self-healing polymer", "new materials, big acts - battery electrode preparation demonstration" and other forms of diverse and interesting experiments，Feel the development and application of new materials and new equipment。In the "Success Time Machine" session, participants walked into the history Hall of Beijing Institute of Technology, experienced the development achievements of the school for more than 80 years through a wealth of historical materials, pictures, physical objects and sand table models, and learned the courage to explore, realistic and innovative dedication of scientific and technological workers passed down from generation to generation。

This "Into the Material" public Science Day activity shows the charm of science to the general public and promotes the popularization and dissemination of knowledge。In the future, Beijing Institute of Technology will carry out more high-quality science popularization activities, provide more opportunities for the general public to contact science, understand science and love science, continue to give full play to the power of science and technology, and contribute to the realization of high-level science and technology self-reliance and construction of science and technology power。
