Promotional video as a motivation for learning science

One of the ways how to motivate students to take interest in a particular topic at a given moment is a promotional video. Because the current generation lives and interacts with the world primarily through IT tools, this is successfully used not only in marketing but in the learning process as well. Especially in the field of science teaching, it is not very popular among young people. Our experience with preparing promotional videos for science topics for secondary-school children will be described. We used both options - professional video processing and low-cost video method. We tried to compare the difficulty of preparation and the resulting effect.
