Get together at beach

Activity 1
Will be a time for socializing and relaxation in a seaside setting. This gathering will allow researchers and students to network, share ideas, and make new friends in a serene environment before the sessions begin.

In a relaxed atmosphere they will be able to discuss their research projects
Activity 2
Activities aimed at the public and elementary and high school students: a- talk to a scientist; b- distribution of scientific dissemination materials; b- dramatization "The Mutation Trial"; c- storytelling for children and adolescents; d- practical activity of measuring the incidence of UV light.
