There are schools that, due to their context, do not have adequate infrastructure to have a science laboratory, which prevents the realization of experimental practices on campus. This situation limits the understanding of the contents of the subject, preventing students from contextualizing and interacting with the knowledge of the subject.Faced with this problem, the use of a virtual laboratory of free software was proposed in order to carry out experimental practices, where students could corroborate the concepts seen and design their own experimental practices.This manual is designed with a total of 20 activities of 50 minutes, where the topics to be reviewed in the subject of Physics II of general high school, for the area of Electricity, are put into practice experimentally in a virtual laboratory of free software.
