Description of the Experience
The study of human body attracts students when it deals with issues linked to their body transformation or to health issues (above all regarding the most common youthful problems). Otherwise students are not curious about anatomy.
The study of human tissues, in general, is one of those arguments less appealing and, in particular, the connective tissue because, since its own characteristics, it is not directly visible. Moreover, students have difficulties to accept that the bones and the blood are actually the same tissue. They diversify only for the chemical composition of the matrix.
For these reasons we realized an elementary experience using a chicken bone completely dunked in vinegar.
The experiment takes several days due to the long-lasting chemical process, but the result is well-rendered: the acid melts the calcium salts composing the matrix of the osseous tissue. These salts are the responsible of the hardness and strength of the bones. As result of the experiment, the bone becomes elastic.
Thanks to this experience the students understood whether the complexity of the human and animal bodies or the relevance of the mineral nutrients in our dietary habits.

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.
