The work describes the adjustments made to the management of a laboratory in the presence of students, i.e., a Zoology Laboratory, in times of pandemic. We discuss the guidelines for students, which are rules designed to avoid the spread of the virus by respecting the provisions of law. The provisions include social distancing, masks, sanitation and ventilation of the environments. Students are also required to declare their state of health to access the university laboratories. For the use of the laboratory microscope in class, a new task for the teacher was to photograph and archive all the zoological preparations that were shown to students. This hindered close contact among students who observe the zoological preparations, and between students and the teacher who gave explanations in class. For outdoor activities, an equally complex organization was required, both to bring the students to the place of the outdoor activities as well to organize contacts necessary for an active involvement of outside institutions, (Foci of the Isonzo Regional Reserve, Miramare Marine Reserve, Museum of Natural History of Trieste) in order to organize group visits on their re-opening after the lockdown.
