Mrs Briggs and her amazing exploding rainbows

Hello, I am Leonie Briggs a science teacher and STEAM lead at a large secondary school in Barnsley, South Yorkshire. Voluntary I am a STEM Ambassador plus Crest Assessor taking on these roles with the aim of inspiring a new generation into an interest and career in STEM.  I’m passionate about this as believe these young people will provide fantastic opportunities benefitting us all for many years to come. 

Lockdown brought a great number of challenges but ever the optimist I began on a mission to turn a negative into a positive really thinking about people of all ages at home. Taking to my teacher twitter @MrsBriggsDA I began completing science and STEM at home experiments following a step by step guide to allow everyone to join in no matter of age, ability or location.

All materials were available around the house using safe equipment and no stress, independent learning. Included are just a sample of worksheets you’d be able to complete at home. Some are demonstrated here on YouTube…

And here are a sample of my worksheets

News soon spread and I was honoured to be involved in STEM Ambassadors live! it was heart warming to watch thousands of people up and down the country performing my exploding rainbows experiments from the event. My aim was then to include rainbows in a number of my experiments as a symbol of hope during these difficult times. I’ve lost count of the number of experiments now completed to allow everyone to follow along!
