How to turn From Source to Sea into a geographical poster or StoryMap with a clear editorial idea.
The Royal Geographical Society's Young Geographer of the Year has a deceptively open brief: From Source to Sea. A river can be treated as a physical system, a habitat, a transport route, a political boundary, a source of risk or a record of human intervention. The opportunity is wide, but the finished piece needs an editorial centre. Students must decide what their river journey is really showing.
The format changes at the oldest age band. Younger categories submit posters, while Key Stage 5 uses an Esri StoryMap. That is more than a software distinction. A poster must establish hierarchy within one visual field; a StoryMap can control sequence, movement and scale. In both cases, the entrant needs to choose evidence rather than display everything discovered during research.
This is a worthwhile competition for students who enjoy connecting place, process and visual explanation. Its school-shortlisting route also means a good piece has two audiences: it must first stand out among entries from the same school, then remain intelligible in blind external review. A focused question and a deliberate map or image choice are more useful than decorative density.

Rated Intermediate. Success depends on accurate geography, purposeful evidence selection, visual hierarchy, and an original treatment of the river theme.
Checked on 2026-09-19: the 2026 theme is From Source to Sea. Key Stage 2, 3 and 4 entrants create a poster, while Key Stage 5 entrants submit an Esri StoryMap. The deadline is 2 October 2026 at 5 p.m., and the awards ceremony is scheduled for 27 November.
Start with a river or river system that gives the student a reason to investigate. The choice might be local and observable or distant and well documented. Then frame a question. How does the river change across its course? Who benefits from one intervention and who bears the risk? What happens when a physical process meets a settlement, farm, dam or protected habitat?
A question prevents the project becoming a labelled diagram of generic river features. It also helps the student decide which scales matter. A meander can be explained at one scale, a catchment at another and water politics at another. Moving between scales is powerful only when the reader can follow why the view changes.
For KS2–KS4, sketch the reading order before making the finished poster. Decide what the viewer should notice from a distance, what they should learn next and which details reward a closer look. A title, central map or image, a small number of evidence blocks and a clear conclusion often communicate more effectively than many equal-sized boxes.
Maps should do analytical work. A locator map establishes where the river is; a thematic map can show flood exposure, land use, pollution or population; a diagram can explain a process. Give every visual a purpose and a readable source. Captions should interpret rather than repeat what is already obvious.
The poster can be creative without disguising uncertainty. If data comes from different years or scales, say so. If a photograph shows one location rather than the whole river, do not imply otherwise. Geography becomes persuasive when the student understands what evidence can and cannot establish.
For KS5, plan the StoryMap as a journey of ideas. Each section should change the reader's understanding: source conditions, a transition, a human pressure, a conflict, an intervention or a downstream consequence. Interactive maps and scrolling images are useful when they reveal relationships. They become distractions when added only because the platform permits them.
Write short, specific transitions between sections. Explain why the reader is moving to a new location or scale. Test the piece on a normal laptop and phone-sized screen, check that map symbols remain legible and confirm that external media will load for a judge without special permissions.
Checked on 2026-09-19: the RGS publishes named winners and winning work from the 2025 competition across age categories and the two school pathways. The prior brief focused on islands, so its subject matter should not be copied; its examples are more useful for observing how successful entrants balance physical and human geography, maps, images and a personal line of enquiry.
Look at what the entrant omitted as well as what they included. Winning work usually feels edited: visuals have roles, facts support a proposition and the finished piece has a recognisable voice. Students should compare examples from their own age band, then make a list of techniques rather than topics.
Checked on 2026-09-19: judging is blind, and the 2026 structure separates state-school entries from independent and international-school entries. Schools may forward up to ten submissions per age category, with one winner and one highly commended entry selected in each category and pathway.
That structure makes school-level selection part of the process. Ask the teacher when the internal cutoff falls, how digital files should be named and whether the school has its own limit or review date. Finishing at the official cutoff is too late if the school needs time to shortlist and submit.
Choose the river and question, then create an evidence inventory: maps, data, field observations, photographs and reliable explanatory sources. Select only the material that answers the question. Draft the visual structure at low resolution, test it with someone who has not read the research and revise where the intended message is lost.
Complete source credits and accessibility checks before decorative finishing. Make text large enough, use colour with sufficient contrast and avoid relying on colour alone to distinguish categories. A visually confident entry is one the reader can navigate without coaching.
Treat From Source to Sea as an invitation to make one geographical argument, not to catalogue an entire river. Use poster hierarchy or StoryMap sequence deliberately, let maps carry analysis and edit evidence with discipline. Confirm the school's internal submission process early, and use official winners to study communication choices rather than borrow content.
