Citizen science is a collaborative approach to scientific exploration. With the discovery and sharing of scientific knowledge as its core value, it expands participation in scientific research to the general public. It is also particularly suitable for use in promoting sustainable education. This design focuses on the development of relevant learning exploration materials and tools for monitoring a river’s ecology, cultivating citizens' awareness of water quality, soil, and the degree of biological damage. This learning set presents biodiversity through ecological stories and visual graphics.
