The present work presents an experimental research we realised in the 2016-2017 school year at "Universul copiilor" [Children's Universe] Kindergarten with Extended Programme, Cluj-Napoca, Romania. The following hypothesis was tested: If the preschoolers are directly involved in learning situations in which they will study the urban environment, then they could acquire some quality knowledge about this type of environment, developing appropriate attitudes and behaviours concerning the urban areas. In the structured experiment, we applied an initial test; we organised more activities of observation in the kindergarten's yard and in other places nearby (i.e. street, school, library, flower shop, etc.). In these places, the preschoolers noticed the urban environment and discussed how to behave in it. After carrying out these activities, we applied a final test. This test showed us increased knowledge, therefore the research hypothesis and the efficiency of the organised learning activities were confirmed.
