Abstract
Sonce je eden izmed največjih alternativnih virov energije, ki ga lahko s pomočjo sončnih kolektorjev zelo dobro izkoriščamo za segrevanje vode in prostorov. Uporabo sončnega kolektorja lahko na zelo nazoren način predstavimo osnovnošolcem. Z uporabo modela sončnega kolektorja učenci spoznajo energijske procese, ki potekajo pri segrevanju vode s sončnim kolektorjem. Predstaviti želim enega izmed mnogih načinov, kako lahko na konkretnem primeru povežemo več fizikalnih pojavov in se iz njih tudi kaj koristnega naučimo. Z meritvami energijskih procesov, ki sem jih na modelu sončnega kolektorja opravila, sem izračunala del energije, ki se porabi za segrevanje vode. Raziskala sem, kam se preostali del energije preusmeri, kje nastajajo izgube in kako pri modelu sončnega kolektorja potekajo energijski procesi. V učnem načrtu za osnovno šolo je ohranitev energije eden izmed pomembnejših konceptov, ki naj bi jih učenci osvojili na vseh nivojih, zato je pomembno, da učencem takšne koncepte približamo na nazoren in njim zanimivejši način. Na podlagi analize meritev sem pripravila gradivo, ki bi učencem omogočalo kakovostnejše razumevanje ohranitve energije kot tudi samega delovanja sončnega kolektorja. Uporaba gradiva je predvidena za izvedbo naravoslovnega dne v osnovni šoli. Posebej sem pripravila še dodatno gradivo za študente Pedagoške fakultete.

Title:Energy flow in a model of the solar collector
Abstract:
The Sun is one of the biggest alternative sources of energy that can be exploited for heating water and living or work areas with the help of the solar collector. The use of the solar collector can be presented to the pupils in primary school in a very illustrative way. A model of the solar collector can help pupils to learn about the energy flow when water is heated using the solar collector. The purpose of my thesis is to present one of many ways how to interconnect many physical phenomena in one specific example and how to learn something from it. I have used the measurements of energy flow which I had carried out on the model of the solar collector to calculate how much energy is used to heat water. I have also investigated where the rest of the energy is diverted, where the losses of energy occur and how the energy in the model of the solar collector flows. Energy conservation is one of the most important concepts in the curriculum for primary schools. All the pupils are expected to acquire knowledge of this field. Therefore, it is very important to present them these concepts in an illustrative and interesting way. Based on the analysis of the measurements I have prepared the material, which could allow pupils to better understand the energy conservation as well as of the functioning of the solar collector. The material is suitable for use in primary schools. I have prepared additional material for the students of the Faculty of Education. The material is intended to be used during a science day.
