Quanta aigua més que terra hi ha al nostre planeta? Authors Adela Terraza Lourdes Figueiras Abstract Once upon a time, there was a school. And in this school, there was a classroom named hawks. And the twenty five children from the classroom named hawks wanted to know everything there was to know about oceans and seas. Therefore they began to ask some questions, to make some agreements, to evaluate their possibilities to obtain answers. And they had a good time studying and talking about science at home. One day, the question was: How much more water than land is there on Earth?, and in the process of finding the answer, they encountered fractions, percentages, square meters, vertices, edges, facets, cubic meters and some very big numbers.
