WP3 transforms methodology into practice by developing the EcoUnity Curriculum: a structured set of 17 lesson plans aligned with the Sustainable Development Goals (SDGs). Designed for students aged 10–14, the curriculum integrates environmental literacy, intercultural dialogue, and active citizenship into everyday classroom practice.

Each lesson combines sustainability topics with collaborative learning strategies rooted in Social Mixing and In-Service Learning. Students do not simply learn about climate change, biodiversity, or responsible consumption — they engage in real-life projects that connect classroom knowledge with their local communities.

The curriculum is interdisciplinary, flexible, and adaptable to diverse school contexts. It supports teachers with ready-to-use materials while encouraging creativity and contextual adaptation. By combining environmental education with inclusion strategies, WP3 ensures that sustainability becomes a shared mission across culturally diverse classrooms.
