Thus, one of the methods frequently used for the direct cognition of environment by small school children is observation. As mentioned by Oprea (1969), the beginner school children “must be teached to see the surrounding objects and phenomena, to understand signification of essential particularities of these objects, to describe them, to formulate opinions related to what they see and to fix in their memory the knowledge they receive” (Oprea, 1969, p.126). For reaching the expected results, observation by school children of organisms, different processes and phenomena from nature, should be directed by teacher by oral questions accompanied by explanations and sometime by demonstration, or by the aid of working papers elaborated for short time, long time, or repeated observations.
