The Big Bang Fair South East
Get Involved

Sponsor the Big Bang Fair South East

The Big Bang Fair South East brings together school children, teachers, STEM employers, STEM Ambassadors and volunteers in a unique festival atmosphere to celebrate all things STEM.  The dates for this year’s Big Bang Fair South East were 26 and 27 June 2019 – watch this space for the 2020 dates.

FREE for schools to attend, the aim of the fair is to ‘inspire students to continue studying STEM subjects and pursue STEM careers with a view to reducing the STEM skills gap’.

At the event in June 2019, over 13,000 school children from 215 schools in the South East took part in hands on activities, workshops, demonstrations and shows put on by over 121 employers, making STEM subjects fun and relevant.

In 2018, 95% of students surveyed enjoyed themselves and 82% said they learnt a lot by taking part.

The event is also host to the Regional Heats and Award Ceremony for the Big Bank UK Young Scientists and Engineers Competition.

Watch the 2019 event video to see why it’s so popular with students, teachers and employers alike.

We will post more details about forthcoming Big Bangs in late 2019 and 2020 on this website.

The Big Bang Fair South East provides a brilliant volunteering experience for employees of STEM organisations, and the benefits are many, for example:

  • With over 13,000 young people attended the 2019 fair, this interactive event we need a large number of volunteers to help the day run smoothly
  • You don’t need a STEM background – although it could help
  • Taking part gives a common, and fun purpose that unites staff
  • It improves team work within teams by giving them something non-target related
  • Improves staff morale, by giving them an opportunity to give back to the community
  • Provides staff development opportunities relating to outreach and promotional skills and realising hidden talents/enthusisam.

If you or staff members within your organisation would like to be a Volunteer in 2019 please get in touch: 01273 642411 /

The Big Bang UK Young Scientists & Engineers Competition is our biggest annual STEM competition.

Students in full time education (Yrs 7-13) can enter.

If you have students who were unsuccessful entrants in our regional heat at the Big Bang Fair south East, they have the opportunity to use their judge’s feedback to develop their project and have a second chance by entering online.

Deadline for online entries is midnight on 8 November 2019.

STEM Sussex coordinates the Big Bang South East programme of events on behalf of Engineering UK supported by delivery partners from across the region. The programme includes Big Bang Near Me events which enable students and STEM organisations to have the great interactive Big Bang event experience on a smaller scale and closer to their schools.

There were 20 ‘little’ Big Bang events across the South East in 2018, and over 13,500 students and teachers from 337 schools attended them.
