With the return to school, the classes have the chance to register for the educational days proposed by Pilâtre de Rozier Organisation. They discover through a short film the hot-air balloon flights, then go inside a hot-air balloon. Afterwards, they are invited to take part in a “hands-on” physics and chemistry class on the properties of air, and then to experiment the making and flying of paper balloons. Finally, through the AéroMusée, they have to find the answers to the historical questions about the balloon. An inspiring outing with pedagogical virtues certified by the National Education and the Regional Natural Park of Lorraine. Already three schools are registered for the next days.
