Small school children comes to school, in the preparatory class, with different empirical concepts (notions) about
nature and its phenomena, formed following discussions with the adults (parents, educator, etc.) or by their own
experience. At this age, the child has knowledge about plants and animals, but these “refers to fragmentary realities,
to particular phenomena existent in their experience” (Bogdan and Stănculescu, 1970, p. 165). This knowledge is
related to external, visible, features of the known plants and animals, such as their shape.
