How to Win the RCSU Science Challenge: Advice From a Winner
Choose a scientific idea you genuinely care about, develop your own perspective, explain it through relatable experiences, then edit hard for clarity and flow.

- Choose a concept that genuinely interests you and gives you something personal to say.
- Brainstorm independently before drafting so your central ideas reflect your own thinking.
- Make difficult science accessible through simple language, relevant examples and relatable experiences.
- Expect to cut heavily: stronger flow and clarity matter more than preserving every early idea.
- Use AI for proofreading or word choices, not for generating the distinctive thinking behind your entry.
What winning the RCSU Science Challenge involves
The RCSU Science Challenge asks students to communicate a scientific idea engagingly to non-specialists. James Son won Jenni Munroe’s 2026 High School Essay category by writing about a concern he had personally encountered: AI systems sounding confident while being wrong.
His method was not to chase the most complicated possible topic. He began with genuine curiosity, developed his own perspective, connected the science to relatable experience and then shortened the draft until its argument and prose flowed clearly.
How to build a stronger RCSU Science Challenge entry
Pick a scientific idea that has prompted your own questions, experiences or opinions.
Common mistake: Avoid choosing complexity merely to sound impressive.

RCSU Science Challenge FAQs
Choose something that genuinely interests or frustrates you and gives you a serious opinion to explore. James chose AI’s deceptively confident mistakes because he had encountered them while revising for his A levels.
James used four stages: collecting ideas and experiences, producing a complete first draft, smoothing the prose while removing irrelevant material, and developing a strong opening hook. His final version was considerably shorter than his first.
Use simple prose, remove unnecessary jargon and connect the concept to experiences a reader can recognise. James grounded his discussion of AI confidence in the familiar experience of a chatbot insisting that a correct solution was wrong.
He used ChatGPT to proofread his own writing and suggest more appropriate words. He deliberately avoided using it for brainstorming because he wanted the essay’s distinctive ideas to come from his own thinking.
James did not get feedback before submitting, so outside comments are not the only route to a strong entry. Whether working alone or with feedback, check clarity, relevance and paragraph flow carefully yourself.
James believed its personal quality mattered: he had clearly considered the issue and developed ideas himself. A judge can often distinguish genuine engagement from an essay written around somebody else’s preferred topic.
James’s advice is to treat the challenge as a chance to explore a scientific idea that fascinates you. Even without winning, you can finish with a researched essay and new thoughts to reflect on later.
