Creation of a Massive Open Online Course on Antimatter for Undergraduate STEM Students

In this report, we present a Massive Open Online Course on antimatter created during the CERN 2021 summer internship, aimed at undergraduate STEM students. We present the motivation, aims and objectives of such a project, its structure and its content. We highlight what we have achieved - the structure, slides, handouts and video lectures. We express what needs to be completed - the translation of the content in French and the filming of the lectures in a professional studio. Finally, we underline our experience of the project and of the internship more generally, discussing other aspects of this journey such as the lectures, the virtual visits and the social events.
