The project relates Physics and Physical Education. The students discover that sport activities are ruled by Physics principles. The pupils learn the laws behind sport exercise and put them into practice in real situations. After some initial work online, they meet each other on two students’ exchanges. The first one is held in Spain and the second one is held in Poland. The students are hosted in both countries by the local pupils. The project is planned using a PBL approach. They students work in international groups and show the results with digital outcomes that are finally disseminated.
