The STEAM project "One Shot" starts from a reflection on contemporary photography, and in particular the possibility of taking endless shots of the same subject with digital devices, without any reflection or understanding of the photographic process. Extending the analysis to the sense of responsibility that leads us to reflect on the effects of our actions, each student, working in a small international group, will make a pinhole camera with which they will be able to take a single photograph. Afterwards, the pictures will be developed and described, they will take part in a competition, a video or a digital photo book will be created and finally they will be exhibited in the school. The project for Italian class 3 is valid as a PCTO.
