Nowadays, a child has to learn about sciences: mathematics, physics, chemistry, biology, but it is more interesting to study and understand how all of these may interact. All theoretical concepts are more valuable when they become practice. The aim of this paper is to prove that biology, which is a multidiciplinary field, including biology and biological processes of living beings, biochemistry and biophysiscs, can be teached, using integrative universal principles of natural science, by transdisciplinarity. This is sustained by the STEAM education, which will help our students to learn concepts, to think creatively and use innovation in solving their problems. STEAM education is important for our students because it removes limitations and stimulates their creativity, innovation, leadership, self-confidence, wonder and critical thinking. Having the multidisciplinary field status, biology as a key part of STEAM education, teaches students to integrate individual components in complex systems, to test theories and principles, to have an overview on different tasks and evaluate and implement their results. All of these skills are transferable into their life actions.
