In the theoretical part of my thesis, I first summarized what can be found in literature concerning electricity treatment (Labinowicz, Driver) and particularities of topics treatment in a preschool period, as well. I presented the concepts of electricity and electrical current, respectively, and several simple devices that operate on the basis of electricity, sources and the concept of electric energy.
In the empirical part I first presented the questionnaire for identification of children's understanding of the concept of electricity. Based on the survey results analysis, obtained with individual interviews, I prepared the set of activities for getting to know the electrical circuit, and presented them to the children via experiments. After that, I’ve checked the children’s perception of electricity again and made the comparison of the results before and after the test.
