  The physics laboratory-works creating and operating computer simulations
experience is described. A significant amount of laboratory works can be
classified as a "black box". The studied physical phenomenon is hidden from
direct observation, the control is carried out by means of electrical measuring
devices. It is difficult to distinguish physical reality from its imitation
when performing such work, so the virtualization of this one does not require
realistic images. The schematic representation of the laboratory installation
greatly simplifies the process of creating a simulator. A unique set of
installation parameters is formed for each student performing laboratory work
on the simulator. These parameters are stored in Google Tables. Their transfer
to the laboratory works html-template is carried out in encrypted form through
the Google Apps script service. The simulator-parameters individualization
contributes to the independence of the student's work when performing
laboratory measurements in the conditions of the distance learning.
