About Jenna Marples

In 2019, Jenna Marples dismantled the myth of the 'boring lab coat' by filming a viral six-minute breakdown of CRISPR gene editing, using nothing but a whiteboard, a kettle, and her grandmother’s biscuit tin as props, to explain off-target effects. Based in Bristol and trained in particle physics at Imperial College, she pivots relentlessly between deep technical rigour and irreverent British humour: her 'Science Without the Jargon' series forced the Royal Society to revise its public engagement guidelines after educators reported a 40% uptick in A-level physics applications linked to her thermal dynamics animations. She refuses voiceover scripts, records live takes with visible eraser smudges and coffee stains on whiteboards, and embeds peer-reviewed citations directly into video thumbnails. Her 2023 collaboration with the UK Met Office produced the first publicly accessible climate model visualiser built for secondary school classrooms, not as a simplified cartoon, but as an interactive Python notebook with real observational datasets.

Frequently Asked Questions

Did Jenna Marples really co-author the Met Office's classroom climate model?
Yes—she co-designed the 'Climate Sketchbook' open-source toolkit in 2023 with Met Office scientists and geography teachers. It uses real-time satellite data streams and lets students adjust albedo or CO₂ inputs while visualising regional feedback loops—not just global averages. The tool is now embedded in England’s National Curriculum for GCSE Geography.
What's unique about Jenna's whiteboard technique compared to other science YouTubers?
She films all whiteboard sequences in single unbroken takes with no post-production edits—forcing precise pacing and conceptual scaffolding. Each board includes marginalia citing primary sources (e.g., 'Per Nature Physics 2022, Fig 4b'), and she reuses boards across videos to build continuity, turning her channel into a cumulative, annotated knowledge map.
Has Jenna Marples published peer-reviewed work on science communication pedagogy?
She co-authored a 2021 paper in 'International Journal of Science Education' analysing how temporal pacing in explainer videos affects conceptual retention in neurodiverse learners. The study tracked eye-tracking and post-video problem-solving in 1,200 UK secondary students and led to her 'Three-Second Rule' for diagram transitions.
Why does Jenna avoid animation software like After Effects in her core videos?
She argues that hand-drawn motion creates cognitive anchoring—viewers retain spatial relationships better when diagrams evolve organically. Her team built custom Python-based rendering tools that convert LaTeX equations into timed sketch animations, preserving the 'thinking-in-progress' aesthetic central to her pedagogical philosophy.
