"Physics Workshop," revised and significantly supplemented, is issued by the fourth edition in order to assist physics teachers in organizing and conducting independent laboratory work of students in grades IX-XI of secondary school. The workshop is coordinated with a new physics program approved by the Ministry of Education of the RSFSR: in addition to compulsory work, it also provides for recommended additional work, and in some cases, options. This significantly expands the possibility of choosing works for the workshop with insufficient equipment of the physical office.
