In light of the current public health situation, CSW Group is sorry to announce that the @Weston Big Bang Fair, that was due to be held on April 24th & 25th and the Big Bang Fair South West in Exeter on June 17th & 18th have both been cancelled

The Big Bang is a national programme which celebrates Science Technology, Engineering and Maths (STEM) careers. We deliver the programme across the South West region hosting several events throughout the year to inspire young people and showcase STEM employers from the region. In the last three years we have reached over 39,000 young people.

Our flagship event, The Big Bang Fair South West is the largest regional celebration of STEM careers. The Big Bang Fair South West 2019 hosted a range of exciting elements under one roof including; a show stage featuring engaging live science shows, a range of hands on activities from the most prominent STEM employers across the region, interactive workshops and the chance to find out about STEM career opportunities. The event is open to primary, secondary and home schooled children.

The event also celebrates and recognises student’s STEM projects. During the day we will host the South West regional heats of The Big Bang UK Young Scientists & Engineers Competition, culminating in a glittering awards ceremony, with the winners progressing on to the national finals the following March at the NEC, Birmingham. A range of other STEM innovation awards are on offer too looking at things like communication, creativity and digital skills.

This event is free to attend.

The Big Bang Competition

Whether it’s a brand new project, or has been completed as part of another competition, all science, technology, engineering and maths projects are welcome. The Big Bang Competition is open to all 11-18-year olds in full-time education or training. Through the process of undertaking a project, we want them to build on and develop their skills and gain confidence and enthusiasm to take their journey with STEM even further.

Why enter? 

  • Allow young people to explore an area of interest and develop independent learning skills
  • Compete for over £20,000 worth of amazing prizes, including the chance to be crowned GSK UK Young Engineer or GSK UK Young Scientist of the Year
  • Opportunities to network with like-minded peers and STEM employers
  • Boost profile of achievement on UCAS form or college application

How to get started

The project can be on any topic in the field of STEM and the options are limitless! Here are some particularly intriguing science project titles we’ve had over the years:

  • What is a bird’s favourite colour?
  • Should we trust artificial intelligence with our lives?
  • How well do we wash our hands?

We’ve also seen many brilliant engineering inventions and designs entered into the Competition and these ideas often stem from where a student has spotted a problem in their community or even in their own homes that they want to try and tackle – be it reducing waste or improving disabled accessibility.
