This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ”The House of Science” that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ”molecular symmetry” as well as the underlying pedagogical theories used to describe learning processes in creative contexts. A model for such a session is proposed, an evaluation is conducted and its results and implications are appropriately discussed. An important review of the mathematical background of symmetries, group theory and linear representations of finite groups was written and can be found in the appendices.
