Inspectors of the Central Technical School conducted for students of MBOU "Gymnasium No. 122 named after Zh. A. Zaitseva" an ecological lesson. The children were accessibly and graphically told and shown what ecological culture is, how to take care of the surrounding world and what rules to follow. The main purpose of such environmental lessons, which inspectors of the Ministry traditionally conduct in schools of Tatarstan, is to form the basics of caring for nature among children. The ecological lesson, with the symbolic name "Green House", will be remembered by first-graders also by acquaintance with the world of rare animals and birds. The children were told about the Red Book and briefly introduced to endangered species. And as applied skills, environmentalists gave advice on how to behave in the forest so as not to get lost. At the end of the lesson, the children were handed textbooks in the Tatar language "Yashel Sukmak" and wished success in their studies.
