The childrens’ responses on each activity demonstrated that experiencing resulted always an increase in
understanding (Table 2). This increase depends both on an age of the participant and whether the knowledge known
previously or not. If the information is known previously, the success of the activity reaches a value of 95%,
whereas if the information is new one, its success lowers down to 76%. The age of the participant is another factor
for the percent of success. In fact, nearly 84% success was achieved by 7-aged children, but 74% success was
achieved by 6-aged participants.
