Science Festivals are public events focused on showcasing science, technology, engineering, and mathematics in a celebratory and engaging setting similar in atmosphere to an arts or music event. Aimed at the general public, science festivals vary widely in form and duration, lasting from anywhere between a day and several weeks, and featuring interactive activities such as hands-on workshops, live demonstrations, lectures, and performances. Many include dedicated programming for schools, but they differ from school-based science fairs, which are aimed primarily at students and parents and are typically held on school premises. Their aims include sparking curiosity, promoting scientific literacy, enabling visitors to interact with working scientists, and making science fun and accessible. Festivals are distinct from other informal science engagement formats due to their temporary, joyful nature and diversity of offerings. The modern science festival concept originated in Edinburgh in 1989 and has since experienced rapid global spread. Hundreds of events now take place annually throughout Europe and North America, and to a lesser extent other parts of the world, supported by associations such as the UK Science Festivals Network, the European Science Engagement Association, and, in the USA and Canada, the Science Festival Alliance. Some of the largest festivals see attendance figures in the hundreds of thousands, and across the world, millions of people participate every year. An emerging body of research literature, situated within a variety of social science disciplines and lenses, suggests that festivals are greatly enjoyed by their attendees, and succeed in boosting science interest, increasing knowledge, and improving perceptions of science among visitors, making them a potential asset for societies that place a high value on scientific activity among the population. However, the events have also attracted criticism for their limited audience diversity, with visitors being disproportionately drawn from highly educated and affluent groups, prompting suggestions that they are ‘preaching to the converted’. In response, some festivals have introduced targeted initiatives such as community outreach and partnerships to attract audiences from underrepresented communities. Despite these ongoing challenges, science festivals continue to evolve and grow as platforms for inspiring curiosity and fostering meaningful public dialogue around key scientific topics.
Science festivals—accessible events that celebrate science and allow the general public to meet and engage with scientists and researchers—have become an established feature of the science communication landscape in developed economies. Distinct from other provisions such as museums or school science fairs, science festivals are characterised by their temporary and festive nature, with many using ‘wow factor’ events such as explosive chemical reactions and hands-on activities to educate and inspire visitors by harnessing the benefits of experiential learning
[1]. Science festivals are also able to provide a different learning experience to in-school provision, and there is a large body of research showing that school trips such as those to festivals boost both cognitive and affective learning
[2].
Although attempts to engage the public in science emerged during the early 19th Century, the modern science festival movement began with the founding of the Edinburgh International Science Festival in 1989. The concept has spread rapidly, with hundreds of such festivals now held every year across Europe and North America, while their presence in other areas such as Asia, Africa, and South America continues to develop.
While science festivals are functionally separate from museums, science centres, and similar institutions, they can be seen as part of the same broad movement in science communication away from a deficit model and towards formats based on dialogue and participation. Rather than a scientist transmitting information one-way to a public that is essentially passive, these experiences promote conversation and even, in some cases, co-creation.
The science festival sector is characterised by its diversity, ranging in size from government-backed powerhouses attracting hundreds of thousands of visitors to small volunteer-led events, and aimed at a variety of audiences, such as adults or families. Theme and emphasis are also heterogeneous; recent iterations in the UK and North America have focused on cutting-edge topics such as biotechnology and AI, while festivals in developing countries may be more concerned with building the STEM (science, technology, engineering, and mathematics) workforce, local challenges, and national development.
As the sector reaches maturity, research interest in the impacts of festivals has developed as a distinct area of enquiry at the intersection of science communication, sociology, and cultural anthropology. Studies, typically drawing on both qualitative and quantitative methods, show that festival attendance boosts science interest and knowledge among visitors. There has also been some critical scrutiny; analysis has shown that festivals tend to attract visitors who are more affluent and highly educated than the general population, prompting suggestions that they are ‘preaching to the converted’. Some festivals have begun to take action to address this issue.
This entry outlines the development of the modern science festival, gives an overview of the different forms it can take, engages with the evidence of the movement’s impacts, and considers potential future developments. It is based on a thorough survey of the literature of the last 15 years, supported by a SCOPUS search of the term ‘science festival[s]’ over the full date range (1970–2025) as well as a similar Google Scholar search to access relevant grey literature.
