I. To promote youth service-learning, this center has planned a series of citizen science lectures, field trips, and workshops with the theme of "Citizen Science." Experts from the National Taiwan Museum, various universities, and relevant professional fields have been invited to serve as course instructors. The aim is to inspire young students to actively participate in citizen science or crowdsourcing projects, design and implement their own service-learning actions, and contribute to ecological conservation and environmental protection. II. Based on the spirit of resource sharing in citizen science, the aforementioned courses are open for registration to people of all ages and regions. Teachers, parents, and students are also welcome to participate together. However, "service-learning hours" are only available for youth students aged 12 to 19 who are registered or enrolled in Taipei City, New Taipei City, Keelung City, Taoyuan City, and Yilan County to apply for upon submission of their achievements according to the activity guidelines.
