Gatsby Charitable Foundation Gatsby are committed to supporting practical science in schools and colleges and the British Science Association have been working with Gatsby to support teachers using practical science with our annual campaign Demo Day which takes place during British Science Week. Demo Day is an annual campaign that aims to inspire secondary school teachers and technicians to explore new concepts, provoke discussions and generate excitement through running science demonstrations. It has run successfully for the last two years in hundreds of schools across the UK. In 2016, we had more Demo Day pledges than ever with, over 655 teachers, technicians and science communicators pledging to take part. In 2014, we released Demo: The Movie, which is a 30-minute film which follows science teacher Alom Shaha as he goes on a journey to explore the use of demonstrations in science teaching. In 2015, we created a new downloadable resource, Demo Insights. This resource is full of ideas and demo insights for teachers, including tips, stories and thoughts from professional science communicators.
