Il Professor Guido Cotti, Presidente della Società ticinese di scienze naturali, ci guida alla scoperta del plancton, il complesso di organismi vegetali e animali che vivono sospesi nelle acque. A rendere possibile la lezione, un innovativo congegno che per la prima volta permette di filmare e trasmettere le immagini di un microscopio. “Telescuola”, 03.06.1962. Di Guido Cotti. Regia di Sergio Genni.
