We present in this article a multidisciplinary approach to teaching high-school chemistry in Serbia, illustrated by an example of the course topic of metals. The aim is to increase the level of interest in studying chemistry and acquiring knowledge that is applicable in daily life. The experiment was carried out in four classes of second-year gymnasium students. The redesigned materials can serve as a model for the preparation of similar materials for other course topics. Multidisciplinary approach in processing of the lesson on metals and the redesigned curriculum content significantly increased the interest of the students and improved their knowledge.
