My first thought, when I heard about the idea of a thesis on the free fall, was that this might be a rather easy task for a student of teaching mathematics and physics. Soon I was proven wrong in this assumption. Plenty of the published works on this topic are highly sophisticated and not at all ordinary. Many physics teachers and, as will be shown, also authors make similar mistakes. When they hear about the free fall or the trajectory of thrown objects they immediately have the description of these phenomena in vacuum in mind. The fact, that air resistance can change something is well-known, but the deduced consequences are sometimes not, or it is assumed that it can be neglegted in most cases anyway. Thus their teaching sets the focus on explaining why the pupils intuitive perceptions are wrong and they immediately start with describing the phenomena under vacuum condition. Both the ideas of phyicisists of the past like Aristotle and the preconceptions of pupils seem to be inconsistant with the taught concepts. The aim of this thesis was to show how complex the topic of free fall and the trajectory of projectiles are and to clarify the mentioned contradictions and other a possibilty how to deal with it in class. For that purpose a variety of fall and throw experiments were made and evaluated by video analysis. The results of these experiments were compared with a detailed description of the physical background. Simultaneously an insight into the conceptual world of important physicists was provided and a comparison to the mentioned findings was drawn. Historical texts as well as current scientific works enabled a broad analysis of this topic in school. The fact, that the subject made plenty of people brood for more than 2000 years until today already proofs that many aspects go beyond the relatively simple and well known concepts. All these insights as well as the created videos were seen as a starting point for a detailed lesson planning about the topic of free fall for different school levels of secondary school. The main emphasis was set on student centered learning and the usage of technologies. Using their own smartphones students can analyse their self-performed experiments and explore the physical concepts themselves. With these lesson plans many competences and topics of the current curriculum were covered to make sure they are practicable at certain school levels.
