Abstract

Avtorji s teoretičnega in praktičnega vidika predstavijo kemiluminiscenco v svetlečih palčkah. Kemiluminiscenca je sevanje svetlobe značilnih valovnih dolžin kot posledica eksotermne kemijske reakcije. Svetleče palčke so zato zanimiv in enostaven pripomoček pri poučevanju kemijskih in fizikalnih učnih vsebin v osnovni in srednji šoli. V uvodnem delu prispevka opišejo teoretične pojme, pomembne za razumevanje luminiscenčnih procesov in reakcijski mehanizem kemiluminiscence v svetlečih palčkah. Na podlagi tabelarične analize učnih načrtov za naravoslovje, kemijo in fiziko v osnovni in srednji šoli pokažejo uporabno vrednost eksperimentov s svetlečimi palčkami v različnih učnih sklopih. Predstavijo več optimiziranih in inovativnih eksperimentov, primernih za osnovno in srednjo šolo.

Secondary title: Using glowsticks in teaching chemistry and physics
Secondary abstract: The authors present chemiluminescence in glowsticks from the theoretical and practical point of view. Chemiluminiscence is a process in which light of characteristic wavelengths is emitted as a result of an exothermic chemical reaction. Glowsticks can therefore be used as an interesting and simple teaching tool in chemistry and physics classes in the elementary and secondary schools. In the first part the authors introduce the concepts needed to understand luminescence as well as the mechanism of chemiluminescence in glowsticks. Analysing the elementary and secondary school curricula of natural science, chemistry and physics the authors identify various topics in which the experiments with glowstics could be used. They present several optimised and innovative experiments suitable for the elementary and secondary school.
