¿Cómo flotan los cuerpos que flotan? Concepciones de los estudiantes

Resum

A research was carried on pupil's ideas, from Primary School to University, on the flotation of cork, wood and ice on water. Different alternative ideas were found, being the commonest the belief in some bodies floating over the water surface, without any submerged volume. Causes of these alternative conceptions are discussed, and some implications for Science teaching -learning suggested.
