The question "how to improve the interest of students to study physics" has been discussed in the author's previous papers too. Within the framework of the project, the author prepared various new interdisciplinary projects to demonstrate how inventions in physics are used in everyday life.

The aim of this paper is to introduce the modules and discuss possible reasons of this situation. (Contains 3 figures.) [This article was prepared with the support of the European Community.]
