This thesis will try to answer important questions such as: How did elements come into existence? Why are some elements more abundant than others? In addition to that, we'll describe the mechanism of element creation, during the beginning stages of Universe's evolution, as well as during later periods up until today. In the work we'll also present some of the most important processes and reactions responsible for the current composition of substances and elements. Descriptions will include various mechanisms responsible for the synthesis of some of the elements. We'll try to explain the processes in the stars in a way that is understandable not only to scientists and physicists, but also to highschoolers. Furthermore, this thesis is an attempt to succintly explain the creation of every important element, lighter as well as heavier ones. Finally, the analysis will cover the material on nuclear physics that is studied in high school through textbooks and compare with the educational results from the curiculum for physics in high school. In the end, the attempt will be made to provide a broader way to include the subjects of nucleosynthesis in the school/educational program
