An interactive art activity to promote student reflection and learning about host-microbe interactions

ABSTRACT The use of art in science teaching can effectively help students understand complex and abstract concepts, particularly in the fields of Microbiology and Microbial Ecology, where the study objects—the microbes—are invisible to human eyes. To explore how different factors shape host–microbe interactions, I developed the activity MicrobiART, which uses mixed art materials to create analogies that illustrate the dynamic relationships between hosts, microbes, and their environments. MicrobiART was presented as an alternative session at a PhD students’ conference in Espoo, Finland. Participants were invited to combine papers, balls, and paint—representing hosts, microbes, and environmental factors, respectively—to create paintings that depict the outcomes of these interactions. The completed artworks were then displayed in a mini exhibition. Following this session, participants were invited to engage in discussion to identify patterns in the paintings and reflect on the analogies’ meanings and limitations. The activity is adaptable to various age groups and to both non-specialist and specialist audiences. Anecdotal evidence suggests that participants understood how interaction outcomes depend on the specific combination of players (host, microbes, and environment), while also recognizing emergent patterns. For instance, interactions within the same environment often share similar colors, contrasting with those from a different environment. Moreover, participants found the experience enjoyable, particularly due to its interactive and aesthetic appeal. These findings highlight the value of integrating science and art in science communication, especially in conference spaces: such integration fosters connections, inspires new ideas and teaching approaches, and provides a relaxed setting for discussion.
