A group of Polish students accompanied by the science teacher created an educational movie showing how to build a solar panel using some domestic materials such as a water container or a chair. In order to construct the model the students had taken part in a lecture done by the teacher so they knew how such a device works. The construction of the device, as well as, recording it required from students a lot of cooperation and commitment and as a result the film perfectly presents all the steps that have to be done to build this device. Students did not only improved their level of English, especiallywhen it comes to increase the span of their technical vocabulary, but also gained knowledge on how such a device works and what science laws govern these rules. Moreover, they will be able to reconstruct the device within domestic facilities.
