This newly revised thematic issue aligns 100% with the fourth module of the profile subject "Health and Social Affairs" in Lower Saxony. It is flexible in its application, depending on how the subject is organized at your school. It provides important foundations for a healthy life and effective prevention, equipping students to handle care in familial, professional, and societal contexts—well beyond everyday school life. The special feature is its clear chapter structure and age-appropriate approaches. The orientation is based on the strategy paper "Education in the Digital World" from the Conference of Ministers of Education. It includes an eBook as a multimedia solution for digital teaching.
