There is no doubt that environmental education at an early age is significant for human development. This paper presents the "RSECed" project, which engages grade 8 learners in Kenya with remote sensing and environmental conservation using Google Earth Engine (GEE). By integrating theoretical and practical sessions, the project introduces satellite-based Earth observation to enhance learners’ understanding of vegetation health, forest cover, and land use classification. Results from 196 participants demonstrated significant improvements in remote sensing literacy, environmental awareness, and digital mapping skills. The study highlights the effectiveness of early environmental education through hands-on geospatial technology, fostering STEM interest and empowering learners as future environmental stewards. The findings emphasize the need for context-specific approaches and further research to support teachers in remote sensing education for sustainable development.
