STEM teaching often involves facts and analytical skills. Yet there must be space for subjectivity and opinions: our duty is also to equip students to address wider implications and discuss controversial and emotive aspects of their subject. Awareness of ethical issues and having to face a diversity of views can seem alien to students trained to focus on objectivity. Interdisciplinary approaches can quickly break down barriers and inspire lateral thinking and encourage the students to consider their subject in a societal context. Approaches borrowed from Drama, Psychology and Music are presented: the aim is awareness, enjoyment and responsibility.
