During the month of May 2021 we exposed the exhibition It´s natural, by the Spanish lgtb association Arcoíris, in the three schools participating in the project. It’s natural is the first exhibition for children on sexual diversity and is related to diversity in the animal kingdom. The exhibition is adapted for the Pre-Primary, Primary and lower Secondary levels, showing from watercolor drawings and simple texts real examples about transsexuality, intersexuality and homosexuality in 12 animal species. The exhibition aims to raise awareness and educate respect for diversity.
