Our project intends to make students and teachers use digital programmes and programming to expand their knowledge in this field by working in the area of energy and natural resources. The focus is on using digital tools and online applications to work on a common topic. We would like our students to gain an awareness of the present ecological situation and take on responsibility for future generations in terms of energy use and sustainability. By combining the development of applications and the reflection of the topic dealt with, we would also like to trigger action and a change in behaviour in using resources so that the project entails long-lasting effects (sustainability). We think common action should be based on a European consciousness and a feeling of belonging to the European Union. The project should use digitalisation as a challenge to level out disparities in the digital / technological progress of the participating schools and to promote digital key skills.
