Issues on Artificial Intelligence (AI) and Machine Learning (ML) are topics which are commonly discussed in public, science and politics. However, these important topics are hardly relevant in school up to now -- moreover, also teachers for computer science often have only little reliable knowledge about AI and its social impact on our future. For this reason, we develop and test teaching materials for the "Science Year AI" that contain not only aspects of computer science, but also social and ethical aspects. The teaching materials are designed in such a way that they can be used across disciplines and even by teachers of other subjects. In this paper, we introduce the simulation game for understanding machine learning that forms the core of the material.
