This bachelor thesis, named Effective Using of Non-chemical Videos in Chemistry Teaching, presents a literature review that is focused on the positive effects of using videos in education and rules that must be considered to fulfill their educational potential. Using videos in education is suitable due to their visual side and attractivity for students, their main benefit is their ability to show abstract topics in a real-life context. It is necessary to edit the video and to connect it with activities and worksheets. Based on the literature review and three non- chemical videos, activities were designed and worksheets were created. The activities and the worksheets were tested in Chemistry lessons and evaluated by the students. Their feedback was used to modify the activities and the worksheets into their final form, which is a part of the bachelor thesis.
