Implementation of Virtual PHET Medium in Explaining Kepler’s Laws

The analysis of experiences carried out on revealing the advantages using integrated PHET medium during the lesson on Kepler’s laws on astronomy has been presented. It has been shown, that using this medium allows us to increase mastery by pupils to 1.5 times in comparison of the traditional teaching using the usual blackboard. It has been revealed that teacher during the lesson can take a passive rather than active role leaving it to the students themselves to carry experiments in accelerated and decreased (to million times) formats of motion of Solar system space bodies. Then the pupil’s quantities with excellent and good knowledge have been increased to 21 and 19 %, correspondingly, as the same time ones with the satisfactory and unsatisfactory grades, contra versa, have been decreased to 17 and 16 %, correspondingly.
