Sandra Beale is a BBC STEM Freelancer, Toddler STEM Contributor to Nursery World, STEM Ambassador Silver Badge holder (200+ hours), and Britain’s leading toddler STEM expert, sharing playful, hands‑on science activities for babies, toddlers, and preschoolers. Her book 50 Fantastic Ideas for STEM Activities won the Creative Play Learning Resources 0–3 Award, and her work has been featured across BBC platforms and national early‑years media.
Sandra has been running Toddler and Early Years STEM for 11 years, delivering sessions at the Cambridge Science Centre, Saffron Walden Museum, local schools and nurseries, and community venues across the country.

Sandra is a mum of three and started Toddler and Early Years STEAM sessions when her middle son was 9 months old. He’s 11 years old now!
What started as entertainment solely for her baby soon grew after visiting friends were amazed at a 9-month-old doing science experiments, and wanted their children to participate in the sessions.

Since then, the sessions have grown and have appeared several times on the BBC, BBC Tiny Happy People, BBC Radio, BBC Breakfast, Early Years TV, local and national newspapers and magazines and were nominated for a STEM Initiative of the Year Award at the Cambridge Science and Technology Awards in May 2023.
Sandra has also been participating in the BBC’s STEM season with a workshop on her Toddler and Early Years STEM sessions. She is also a BBC STEM Freelancer.
She has done Toddler and Early Years STEM sessions at the Cambridge Science Centre in 2021 and at Saffron Walden Museum in 2020 as well as with local primary schools and nurseries and at a local French Restaurant in Saffron Walden.
She has also been running Toddler and Early Years workshops at the Saffron Walden Library since the summer of 2024.
Sandra’s Toddler and Early Years STEM have been raising funds for BBC Children in Need since 2020.
Her Toddler STEM sessions are held every Monday and Thursday morning at her home at 9:30am for an hour throughout the year.
The sessions are run with a bigger group and more varied ages during half term and holidays. There are various themed sessions also depending on the time of year.
