Three students in school uniforms work through open books at a classroom table, with textbooks and stationery nearby and study notes on the whiteboard behind them.

Where Can Students Find NUS Chem•Comm Challenge Rules?

Find the Chemistry•Communication Challenge, also called Chem-dot-Comm, through NUS Chemistry’s Events page and the edition-specific rules page. The organiser’s instructions are the starting point for school teams.

On 18 October 2026, the reviewed rules page is still headed “The 28th Chem•Comm Challenge (31 May 2025)”. Its dates have passed. Use it to understand that edition, not as proof that a new registration window or unchanged future rules exist.

Did you know? Chem•Comm is a scientific communication challenge, not simply a paper of Chemistry questions. NUS describes an odd-year biennial event involving oral presentation and media. Explaining an idea clearly is part of the learning.

Practical checks before you act

Check the edition before forming a team

The 2025 rules describe Year 1–4 secondary students, teams of three and a limit of two teams per school. Those are useful historical specifics, not rules this guide can promise for an unannounced edition.

Ask your Science teacher which invitation the school is using and who coordinates team entries. Save the edition and source link beside any proposed topic. If a forwarded message lacks a year, resolve that before distributing work or creating a website around a presumed theme.

Read the website and presentation as separate tasks

The documented format includes both a website and slides; the rules explain that the presentation should do more than demonstrate the website. Read those components together before deciding what an entry needs.

For planning, give each component a clear job. A spoken explanation might introduce the question and reasoning, while a page lets a reader inspect evidence and references more carefully. These are preparation suggestions, not substitute submission rules. Check the intended edition’s technical and timing requirements before building the final materials.

Make scientific claims traceable

The 2025 rules require acknowledgement of externally sourced media and assess accuracy as well as communication. A visually attractive page is not enough if its explanation cannot be checked.

Keep a source note for every important claim: what it says, where it came from and how it supports the explanation. Separate an image that illustrates an idea from data that actually tests it. If a source is unclear or contradicts another, discuss the uncertainty with your teacher rather than selecting whichever sentence sounds more impressive.

Prepare every member to explain the work

The old rules involve all team members in presenting and provide for judges’ questions on the chosen topic. Do not assume one confident speaker can replace everyone else’s understanding.

Try a rehearsal in which a teammate asks a genuine question without first seeing the script. Notice where the explanation depends on an undefined term or skips a causal step. Improve that connection before adding more slides. Keep the student voice honest: explain the ideas you understand and identify what still needs checking, rather than memorising an answer you cannot defend.

What to do next

Read the NUS event description and the dated rulebook, then ask your school about the intended edition. Treat the 2025 showcase as past work to learn from; obtain current instructions before selecting a competition theme or submitting an entry.

Explore the connected learning guides

Choose the question that brought you here. Open one useful guide, try a small task, and stop when you have what you need.

Take one question further

The same learning habit can travel across subjects, while each subject keeps its own methods. These routes help you notice a difficulty, understand one part of it, and return to something you can do.

A word is familiar, but using it is difficult.

Move from recognising a word to retrieving it in a new context. Understand vocabulary plateaus.

Try it without the guide: Choose one word you already know. Close the guide and use it in a new sentence. Explain why it fits; try another context tomorrow.

A piece of writing has ideas, but the reader loses the thread.

Make the order of events and the links between sentences clear. Explore composition writing.

Try it without the guide: Choose one short paragraph. Read the relevant explanation, close it, and revise the paragraph. Ask someone to tell you what happened and why.

The Mathematics seems familiar, but marks still disappear.

Find the first point where the working stops being reliable. Find Secondary 4 A-Math mark leakage.

Try it without the guide: For a Secondary 4 A-Math question you have attempted, locate the first uncertain line. Repair that step, then try a comparable question without the worked answer.

A Science fact is remembered, but the explanation is incomplete.

Connect the evidence to a scientific idea and the resulting change. Follow the Primary Science learning route.

Try it without the guide: Choose a familiar Primary Science example. Explain the evidence, the idea and the result without notes. Then change one condition and explain your prediction.

Two accounts of the world seem to disagree.

Check the question, source, date and evidence before combining claims. Explore the World Knowledge research library.

Try it without the guide: Take one claim. Find the source best placed to support it, note its date, and state what remains uncertain. Return to your original question.

There is plenty of help, but independence is hard to see.

Check what the learner can understand and do after support is removed. Understand how education works.

Try it without the guide: Choose one small task the child has practised. Agree on a calm, brief attempt without prompts. Use what happens to choose one next step, then stop.
