Her content often combines the traditional online style with education in the hope to inspire a new audience to stay curious, adventurous and encourage science engagement. Maddie’s YouTube channel received a Kidscreen Award in 2022. 

In addition to online content, Maddie’s television career started with the CBeebies series Maddie’s Do You Know?. The hugely successful show which ran for 5 series, saw her explore the workings of everyday objects by asking how they are made or work, all made possible with special cameras and animations. In 2017, Maddie was awarded BAFTA Children’s Awards for her work on the series.

In addition to DYK, Maddie has hosted Make Yourself At Home (Discovery+/Max), Something Special with Mr Tumble (Cbeebies), Maddie’s Urban Jungles (YouTube Original) Springwatch Wild Academy (BBC) and Show Me The Honey (CBBC). 

In addition, she has contributed to The One Show (BBC), Morning Live (BBC), This Morning (ITV), The Gadget Show (Channel 5) and Goodwood Festival coverage (ITV). 

Since 2021, Maddie has worked with Penguin’s Puffin releasing three non fiction books for children, Stuff, A Very Curious Christmas and most recently How Does It Work?. 

Aside from digital content and television, Maddie also brings STEM subjects to the stage, writing, producing and hosting shows for her audience. She regularly appears at festivals across the UK, and made her West End debut in Maddie’s Very Curious Christmas at the Apollo Theatre. The show received an Olivier Award nomination in March 2025. 

Content collaborations have included Kew Gardens, Amazon Echo, LEGO, Samsung, Dr Oetker, LeasePlan and Mattel. 

She is a patron of the Youth STEM Awards (YSA) scheme and an ambassador for The Wildlife Trust and Eureka: The National Children’s Museum.
