科普 (kēpǔ) is a noun meaning 'popular science' — the activity of explaining scientific knowledge in an accessible, engaging way for the general public. It combines 科 (kē), short for 科学 (kēxué, 'science'), and 普 (pǔ), from 普及 (pǔjí, 'to popularize' or 'to make widely known'). Together, they literally mean 'popularizing science'. This term emphasizes clarity, accuracy, and audience-appropriateness — not oversimplification, but thoughtful communication that bridges expert knowledge and everyday understanding.

科普 appears widely in contexts like science museums, educational TV programs, children’s books, online videos, and outreach events — especially those aimed at students or non-specialists. It often focuses on topics like space, biology, environmental protection, or health, and frequently features real-world examples, vivid analogies, and visual aids. In China, government-supported科普 initiatives are common, reflecting national emphasis on scientific literacy and public engagement with evidence-based thinking.
