Main value of the experimentation method kindergarten It is that in the experiment:

• Children are given real insights about the different sides of the object under study, its relationship with other facilities and habitats;
• The child ' s memory is enriched, his or her thought processes are intensified, as there is a constant need for analysis and synthesis, comparison and classification operations;
• The child ' s speech is evolving, as it is necessary for the preschool to give an account of the sights, formulate the identified patterns and conclusions;
• There is an accumulation of a smart reception and operations fund that is considered mental;

Experimental work gives the child an interest in nature research, develops thought operations (analysis, synthesis, classification, synthesis, etc.), stimulates the child ' s learning activity and acquiescence, enhances the perception of educational material on natural phenomena, mathematical knowledge, ethical rules of life in society, etc.
