We applied three-tier didactic test. Answers of respondents are evaluated by Cronbach´s alpha. Respondents have a deficiency of knowledge about oxygen. They cannot distinguish between the density of oxygen and density of air. Respondents also cannot identify O3 molecule of oxygen (ozone). Correction of the misconceptions is very important part of the educational process. It is the aim of this process.
