Cosmic rays, discovered in 1912, are high-energy particles originating from outer space. They carry rich information about celestial evolution and the universe and represent the only material samples, which humans can obtain from beyond the solar system.

Cosmic ray observation touches on the frontiers of particle physics and astrophysics. The methods and instruments used in the experiments include detectors, electronics, computers, automatic control systems, Global Position System , and data transmission and processing, among other modern physics knowledge and technologies.

This report introduces the construction of China’s first campus cosmic ray observation station, the establishment of the Campus Cosmic Ray Observation Collaboration, and the expansion of cosmic ray observation activities to many schools in China. It also covers participation in international exchange activities and the achievements made. After five years of development, reflections and recommendations are provided for conducting such activities in different schools and regions.

The results of this series of practical explorations demonstrate that conducting campus cosmic ray observation activities, with students directly guided by scientists and teachers in real scientific research, stimulates students' curiosity, imagination, and desire for exploration. This lays a solid foundation for cultivating innovative talents in the future.
