A. Naranjo at Merida. The name Brasileirinhos, meaning "Young Brazilians", was chosen by the winners of the third Grande Desafío organized by the Museu Exploratorio de Ciencias of the Universidade Estadual de Campinas to encourage all Brazilian students in their efforts to achieve the necessary goals in their studies.
