- Chemistry experiments have been an issue of vivid discussion for more than fifty years now. Though there are many who hold a stand-offish position, there is a general notion chemistry experiments inherently belong to chemistry instruction. In this study, attention was given first to the frequency that Czech teachers at both lower and upper-secondary schools use experiments, demonstrations, laboratory work etc. A random, generalisable sample of 354 teachers filled in a questionnaire. The results showed experiments are used only seldom at lower-secondary schools and lyceums, more frequently at grammar schools, yet just “at least once a month”. Safety showed as one of the barriers. The teachers expressed general knowledge about a norm which covers the topic, however in their further responses they expressed a lack of awareness of the compounds their students are allowed to work with. These findings are a call for measures such as: developing a database of well-described procedures including safety regulation remarks or a simplified, easy to follow list of up-to-date regulations.
