The modern science festival movement has grown significantly since the Edinburgh International Science Festival launched in 1989. Hundreds of science festivals now occur annually and vary widely. This article examines how the term “science festival” is used within research and practice. We find that most research articles fail to describe the science festivals they study. A subsequent analysis of festival websites and other publicly available information confirms the wide variability of science festival formats, which suggests the need for descriptive information about science festivals in scholarly work.

Over the past decade, science festival expos have emerged as popular opportunities for practicing scientists to engage in education outreach with public audiences. In this paper, a partial proportional odds model was used to analyze 5,498 surveys collected from attendees at 14 science expos around the United States. Respondents who report that they interacted with a scientist rated their experiences more positively than those who reported no such interaction on five categories: overall experience, learning, inspiration, fun, and awareness of STEM careers. The results indicate that scientists can positively affect audience perception of their experience at these large-scale public events.
