It is the afternoon of Saturday, May 16, 2009. The experiment does not take much time, as the girl demonstrates her interest and desire to communicate with a new person. The very experiment takes about 30 – 40 minutes. Before the experiment, her parents told that she could easy talk with unknown people, but only being in her room; this is why the place for this observation was obvious – Jenny's room.
The first experiment is connected with conservation of volume. Piaget tells a lot about the abilities of children of five and six years and admits that their abilities to conserve are not perfectly developed. "Their thought processes are dominated by the appearances of things, and they do not realize that the volume of an object may not change just because the appearance changes." (Hobart, 155)
