The Big Bang Fair South West 2020 will host 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 and the chance to find out about STEM career opportunities.


The event is open to primary, secondary and home schooled children.



Due to popular demand, the event will be held over 2 days and will attract over 11,000 visitors from across the South West. There will be a number of sessions available to book onto over the 2 days. Please see below for details:

* 9:00- 10:00 of this session will be a Sensory Friendly Hour. Big Bang events by nature are loud due to the highly interactive content. For the first hour of this session adjustments have been made to reduce the noise levels in the arena which may be preferable to some visitors. 

Session 2  12.30-15.30


Big Bang Competition- South West Regional Heat

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.

We will be hosting the regional heat of the competition on Wednesday 17th June. If you are booking for a team/individual you will need to book onto the morning session on this date, your group will stay at the event for the whole day in order to have the opportunity to experience the fair once judging has finished and attend the glittering awards ceremony in the afternoon.


Once you have registered onto the morning session, please email to register your interest in entering teams into the competition. The competition registration will open early next year and you will be notified at this point to enter all your project details.
