“Be the change” (BTC) was the theme for Cheltenham Science Festival. BTC set out to empower audiences as individuals and as a collective to enact positive change across a wide range of global issues linked to the UN Sustainable Development Goals. We examine the role of theming within festivals and analyse how BTC centred social change within the science festival. We conclude by noting that science festivals do not have to have science, technology, engineering or maths (STEM) themes, but can instead be themed around global social issues.

The workforces of the Science, Technology, Engineering & Mathematics (STEM) industries suffer from skills gaps and lack diversity. Science engagement activities often try to solve these problems through targeting audiences under-represented in the STEM workforces. There is limited data, however, to suggest that these engagement efforts are successful in translating into more diverse workforces. We draw upon Unicef’s ‘Sport for Development’ model and propose a new conceptual framework: ‘Science Engagement for Good’. This frames science engagement activities around the benefits to individuals, families and communities, rather than the benefits to STEM industries, the economy or society at large.
