Abstract. The choice of the teaching tasks as the main didactic tool for developing of health-ecological competences in chemistry education is reasoned. Criteria for the classification of chemistry tasks with health-ecological orientation, which can be used in the composition and selection of such tasks, are derived. On the basis of the proposed criteria, a classification of chemistry teaching tasks with health-ecological content is created. It is the basis of the developed system of chemistry tasks in the learning of specific educational content in view of forming health-ecological competencies in students. The appropriateness of the composed teaching tasks with health-ecological content is proved by pedagogical experiment. Its results show that the designed didactic tools succeed in achieving the goals of forming health-ecological knowledge, skills and value attitudes in adolescents.
