"For whom the Calandra tolls?": zoological laboratory (III) of the formative proposal of inclusive scientific divulgation

Blind people, though not seeing the world, is nevertheless able to imagine it, activating mental processes different from those of the sighted. They can come in contact with the reality of the world and know it with appreciable effectiveness (Angeli F., 2012). It has been imagined that only the view was the capable sense of allowing the conception of space and its forms. Of course, it was the facts that showed, with increasing clarity, that the lack of sight does not prevent the mental construction of space. Although touch is generally regarded as the sight of the blind, it is important to understand how sight cannot be validly replaced by a single sense. To organize a good relationship with the surrounding reality, the person who does not see needs to activate the whole of their residual senses. In particular, the complementarity between touch and hearing makes us understand like the blind. The touch sense has a very small perceptive field and therefore proceeds bysuccession of spatial fragments, but also presents a very analytical capacity,refined and punctual. Hearing has a greatly extended perceptual field, whichallows the blind to have a broad overall spatial reference but offers insufficient information on the objects and on the particular characteristics of the surrounding space (Coppa M.M., 1997).We have therefore devised a playful-practical laboratory to allow a sensory disabilitypublic,with various degrees of blindness, to reach zoological and scientific contents and then re-connect to more general problems such as the numerous environmental emergencies of this decade. Thanks to a convention between the "IstitutodeiCiechiOpereriunite I. Florio - F. ed A. Salamone" of Palermo and the "Consiglio Nazionale delleRicerche - Istituto per lo studio degliimpattiAntropici e Sostenibilità in ambientemarino" of Capo Granitola (TP), we start with the project "The world of birds", developed from January to April 2019 and divided into three main themes. The third of which is the focus of this report: Nest and songs.
