Abstract
In order to clarify the learning process of children, two studies were carried out. The purpose of the experiment in the first study was to make children distinguish the difference between two phenomena. In the second study the purpose of the experiment was to make children compare volumes in a phenomenon. Both studies had the same sample and test method. Forty-four first year students in junior high school comprised the sample. Free answer style test was used. The results of the two studies are summarized as follows: 1) Children achieve the purposes of the two experiments. 2) There is a difference in the weight vectors of the phenomena investigated in the two experiments.
