Collection of tasks, tasks. Chemical tournament 8-11 grade. Aleshin G. Yu.

This collection contains the conditions and examples of solving the problems of the interregional chemical tournament held in Moscow (2011-2017). The tournament format involves the solution of non-standard natural-scientific meta-subject problems. These tasks can serve as a source of ideas for design work, and is successfully used by teachers in extracurricular activities. The collection will be useful primarily to schoolchildren interested in chemistry, as well as teachers of chemistry, physics and biology.
