You are here

Big Biology Days are a one-day science festival, bringing together a variety of biological organisations under one roof to celebrate the life sciences by engaging the general public with an array of hands-on activities, displays and talks.


These are becoming a more and more popular option for those wanting to get involved in outreach as an opportunity to share their passion for biology and the natural world, regardless of scientific background. During our anniversary year, we are offering 10 grants of up to £500 each for you to run your own Big Biology Day in your local area.

The RSB Big Biology Day grant scheme is now closed to applications.

Past events

In previous years, Big Biology Days have been held across the UK in Staffordshire, Cambridge, Cardiff and more - we’d love to help these festivals grow and spread across the country and internationally, and hope that you are inspired to run your own.
