I want to show a pathway to teach Genetics based on new methods who use epistemology and history to study the different models created by scientists in the century: the mendelian model (by the analysis of original papers and the historical and social situation in which Mendel lived), the model proposed by Morgan (who studied Drosophila melanogaster), the Watson and Crick's model of DNA. Very important are also experiments in laboratory (such us to take off DNA from the fruit's cells, the PCR of meat etc.) and the production of a performance named In-certezze
. The theatre is used to convey information but also the scientist's attitude and the social and moral problems of the research. It is also a way to teach amusing and exciting. The message of the performance is that science is neither good nor bad by itself, but it depends by the use that man does of it.
