I don't think self-study is such a part of elementary school. For reflection, I chose my first lesson, which I learned at this school. It was a physics class at 7. B on the subject of a connected vessel. At the beginning of the lesson, students are used to showing their experiments and lecturing projects (a project is an elaboration of a certain topic in the field of physics). I had to follow this tradition.
