The children tend to have junk food with a lot of packaging with two problems, health, and rubbish. We want to work through problem-solving methodology in order to lead the children to identify the problem and find different solutions (0 km food, reduction of waste and rubbish) to different problems., (allergies and obesity, pollution, etc). The students will synergically work through surveys and research to investigate the reality, they will discuss and debate to find solutions, they will create leaflets and materials to disseminate their research and products among the school community and beyond.
