Description of the Experience
Many years of working experience allow me to state that each year students have a problem with the mastery of knowledge about the structure of deoxyribonucleic acid, so after discussing this issue I devote one lesson to the performance by the students of the DNA molecule with plasticine and soft wire. At the beginning of the course we repeat DNA structure. I write all the elements included in the molecule unsubscribed on the board. Then we choose the colors of plasticine for the nitrogenous bases, sugar and phosphoric acid residues, and we determine how we can form hydrogen bonds. After such instruction, students carry out a model of the double helix, during the work I approach each person and I give extra hints if something is still unclear. I appreciate their hard work and commitment. At the end of the lesson young people are preparing an exhibition of their models.
By using the same theoretical knowledge both visual learners and kinesthetic learners very well remember the construction of deoxyribonucleic acid. The measure of the success of the students is that if I ask them to characterize the structure of DNA they list correctly all the components of the molecule.

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.
