On September 8, an event was organized in our kindergarten where each of the preschoolers could feel like a real scientist, experiencing the joy of experimenting, discovering something new in the familiar. All children are inquisitive by nature, each of them is an inquisitive researcher. Therefore, the children are happy to “turn” into scientists and conduct various experiments, experiments, and research. The children transformed into real surgeons, laboratory assistants, anesthesiologists, and uzologists and performed a complex operation to remove germs and bacteria from the abdominal cavity of the exhibit doll. The children had a lot of fun and positive emotions and felt like doctors and perhaps someone would choose this profession for themselves.
