This experience is relevant because it allows to easily face a topic of Chemistry which is more complex if faced with formulas and calculations. Following the current experience, the use of formulas and calculations comes only after the initial experimental approach that makes the students aware about the usefulness of the subject to understand the world around them. Moreover, the proposed laboratorial activity fosters the students’ interest towards the studied topics and intrigue the students with their direct involvement.


Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
