Optimizacija eksperimenta za ponazoritev evapotranspiracije pri naravoslovnih predmetih

Praprotnik, Luka (author), Žmavčič, Tea (author), Torkar, Gregor (author)

Namen prispevka je predstaviti izvedbo eksperimenta, s katerim ponazorimo proces evapotranspiracije, ki je eden ključnih procesov za razumevanje kroženja vode v naravi in pretoka snovi v rastlini. V eksperimentu smo merili vpliv različnih sestojev vegetacije in vpliv vetra na stopnjo evapotranspiracije. Rezultati, ki smo jih pridobili s pomočjo tehtanja ter merilnega sistema Vernier LabQuest 2 so pokazali, da vzorec poraščenosti tal vpliva na stopnjo evapotranspiracije. Prav tako smo ugotovili, da je veter eden izmed pomembnih dejavnikov, ki pospešijo proces evapotranspiracije. V zaključku opredelimo možnosti uporabe opisanega eksperimenta pri pouku naravoslovnih predmetov.

Abstract

The purpose of this paper is to describe the experiment, which illustrates the process of evapotranspiration. This is one of the key processes for understanding water cycle in nature and movement of water in plants. Effects of different patterns of vegetation and the wind effect on the rate of evapotranspiration were measured. The results obtained with weighing pots and measuring systems Vernier LabQuest 2 showed that different patterns of vegetation influence on the rate of evapotranspiration. Wind is also one of the important factors that accelerate the process of evapotranspiration. In conclusion, implications for teaching science using the described experiment were discussed.
