Uporaba svetlečih palčk pri pouku kemije in fizike

magistrsko delo

Maša Kenda (Author), Bojan Golli (Mentor)

Abstract

Kemiluminiscenca, ena izmed vrst luminiscence, je sevanje svetlobe značilnih valovnih dolžin kot posledica eksotermne kemijske reakcije. Ta poteka znotraj svetlečih palčk, ki jih lahko uporabimo pri poučevanju fizikalnih in kemijskih učnih vsebin v osnovni in srednji šoli, da z njimi učencem vizualiziramo težje razumljive pojme in tako povečamo notranjo motivacijo za učenje naravoslovja. V magistrskem delu bom razvila eksperimente s svetlečimi palčkami primerne za uporabo pri pouku, s katerimi dosežemo čim več ciljev učnega načrta za fiziko in kemijo v osnovni šoli in splošni gimnaziji. Z njimi želim učence navdušiti za naravoslovje ter izboljšati njihovo razumevanje. Ker so svetleče palčke učencem poznane iz vsakdanjega življenja, so zanimiv pripomoček za eksperimentiranje v šoli, zato zagotovo sodijo k sodobnem pristopu poučevanja naravoslovja.

Secondary title:	Using glowsticks in physics chemistry and class
Secondary abstract:	In my master thesis I present theoretical and practical aspects of chemiluminescence in glow sticks. Chemiluminescence is one of many types of luminescence and means radiation of light of characteristic wavelengths as a result of exothermic chemical reaction. This process takes place inside of glow sticks and can be used in physics or chemistry classes in primary and in secondary school. With glow sticks (that radiate different colours) we can easily visualize difficult-to-understand concepts to students and we can also increase student's motivation for studying natural sciences. The theoretical part describes the concepts important for understanding luminescence processes, the chemiluminescence reaction mechanism in glow stick, the analogy with the functioning principle of lasers and also the advantages and benefits of student's independent experimental work with glow sticks. In the experimental part, there are 5 optimized experiments with glow sticks which can be used in classes. With experiments we can achieve many objectives of the curriculum in physics and chemistry in primary and secondary school. The experiments are: a) Proof that hydrogen peroxide is a reagent in the reaction in a glow stick, b) Determining which substance is formed in the reaction in a glow stick, c) Anayisis of the influence of base and acid on the emission of light, d) Determining whether the energy is released or absorbed during the reaction in a glow stick, e) Display of additive light mixing. Each experiment is also equipped with a worksheet for students and the teacher.
