Science Education through Earth Observation for High Schools (SEOS) is an initiative for using satellite remote sensing of the Earth in science education curricula in high schools. The project was funded by the European Commission (EC). Implemented by 11 partners from European countries and in cooperation with the European Space Agency (ESA) it offers 17 tutorials on environmental and scientific topics. They cover many disciplines such as physics, biology, geography, mathematics and engineering, focusing on the interdisciplinary character of environmental education. They may also serve to improve language skills.
