On July 2, the “Physics Horizon” Popular Science Education Practice Base of the School of Mathematics and Physics visited Heishanzhai School in Yanshou Town, Changping District, Beijing, to carry out a Science Day event. Combining popular science lectures with hands-on scientific experiments, the event allowed students to experience the charm of science up close and sparked their interest in scientific exploration. More than 70 students from grades 4 to 8 participated in the activities.

In the morning, Professor Ding Hongsheng delivered a lecture titled “The Wonders of Superconductivity.” Through demonstrations of superconducting magnetic levitation experiments, he introduced the basic properties of superconducting materials and their applications in fields such as healthcare, energy, and transportation, arousing the students’ strong interest in learning.

Associate Professor Xie Ziang presented a popular science lecture titled “Chasing Light and Harnessing Wind—Unlocking the New Journey of Low-Carbon Energy.” Starting with clean energy sources such as solar and wind power, he introduced the development and application of new energy technologies, guiding students to pay attention to green and low-carbon development.

In the afternoon, students participated in hands-on scientific practice activities in groups. During the session “How Does Electric Current Become Music—The Mystery of Loudspeakers,” students built simple loudspeakers themselves, learning about the principles of electromagnetic induction and vibration-induced sound. In the “Optical Magic Wall—Exploring Polarization Phenomena” activity, they observed polarization effects to explore the nature of light. Both practical activities combined education with entertainment, allowing students to experience the joy of scientific inquiry through hands-on operation.

This event was a vivid demonstration of the School of Mathematics and Physics “Physics Horizon” Popular Science Education Practice Base serving grassroots science education and helping to enhance the scientific literacy of young people. In the future, the base will continue to leverage the university’s disciplinary strengths and talent advantages, carry out popular science activities in diverse forms, bring more high-quality popular science resources into primary and secondary school campuses, and contribute to cultivating teenagers’ scientific spirit and innovative consciousness.
