Uporaba poskusov z radonom v aktivnem pouku

magistrsko delo

Abstract

Radon je radioaktivni žlahtni plin, ki nastaja v zemeljski skorji kot del uranove razpadne verige. Sčasoma pronica skozi plasti zemlje do površja in se lahko v večjih koncentracijah nabira v zaprtih prostorih. Čeprav je radon znan predvsem po nevarnih učinkih na človekovo zdravje, lahko njegove kratkožive radioaktivne potomce uporabimo pri izdelavi preprostih radioaktivnih virov za uporabo pri šolskem pouku. V magistrskem delu je predstavljen razvoj nove učne aktivnosti, ki je zasnovana na uporabi znanih poskusov z radonom. Razvoj aktivnosti je potekal iteracijsko v dveh stopnjah. Aktivnost je zasnovana na teoretskem okviru pristopa ISLE (Investigative science learning environment) in vključuje poskuse s preprosto šolsko laboratorijsko opremo ter viri radioaktivnega sevanja, ki so posledica razpada radona.

Secondary title:	Using radon experiments for active learning
Secondary abstract:	Radon is a radioactive noble gas formed in the Earth’s crust as part of the uranium decay chain. Over time, it seeps through layers of soil to the surface and can accumulate in higher concentrations indoors. Although radon is known primarily for its dangerous effects on human health, its short-lived decay products can be used to make simple radioactive samples for use in school lessons. This Master’s thesis presents the process of developing new learning activity based on the use of known radon experiments. The development of the activity took place iteratively in two stages. It is based on the theoretical framework of ISLE (Investigative science learning environment) approach and includes experiments with simple school laboratory equipment and radioactive samples resulting from the decay of radon.
