Writing, Posters and Presenting

By the end of this guide you will be able to turn finished research into a paper, an abstract, a poster, and a short talk, and then defend it in front of a judge. It also walks you through the rules and forms that science fairs require, so a missing signature never knocks out a good project. You don't need any writing experience beyond school essays.

What you'll be able to do when you finish

• Write a research paper in the standard Introduction, Methods, Results, and Discussion format, with each section doing its own job.
• Write a 250-word abstract that a judge can read in a minute and remember.
• Make figures and tables that a reader understands without your help.
• Cite sources correctly in APA, MLA, or IEEE style, and use AI tools within competition rules.
• Design a poster or tri-fold board that reads from across a room and passes a fair's display and safety inspection.
• Give a 2- to 3-minute pitch and answer hard questions calmly.
• Know which forms and approvals your project needs, and when each one has to be signed.

How each chapter is built

Each chapter starts with what the piece of work is for, then shows how to do it, then gives a worked example you can copy the shape of. Sample boxes hold real writing: a full abstract, a methods paragraph, a pitch script. Tables collect rules and mistakes in one place so you can check your own work against them. Every chapter ends with a short Check yourself list. If you can answer those without looking back, move on.

The examples follow one invented project so you can see a single piece of research move from paper to poster to pitch. A student studies whether neighborhoods with more tree canopy have cooler summer surfaces, using free satellite data for one county. The numbers are made up for teaching and are not real findings.

Where this guide fits

This guide covers the last stage of a project, Present. If you still need a question, read "From Idea to Research Question". If you still need sources, read "Finding and Reading Research Papers". For the analysis itself, see "Statistics for Research", "Python for Machine Learning", and "Machine Learning Foundations". Chapter 13 on rules and forms is the exception. Read it before you collect any data, because some approvals must come first.

A suggested pace

Work backward from your fair date. Most students need about three months from "the experiment is done" to "ready for judges", and the paperwork starts much earlier.

Your fair may require the paper or abstract earlier than this, often with registration. Check your fair's deadlines on its website in the fall and write them into this table. Your mentor can help you skip ahead to whatever your fair asks for first.

A research paper is a report with a fixed shape, so readers can find what they need fast. This chapter explains that shape, what each part does, and the small pieces around it: title, keywords, and acknowledgments.

The IMRaD structure

Most papers in the sciences follow a pattern called IMRaD: Introduction, Methods, Results, and Discussion. Each section answers one question for the reader.

Around those four sections sit the title, the abstract (a one-paragraph summary, Chapter 3), keywords, sometimes a short conclusion, acknowledgments, and the references. Engineering projects often rename the sections (Problem, Design Criteria, Prototype, Testing, Evaluation), but the logic is the same.

Readers rarely go front to back. A judge or scientist usually reads the title, then the abstract, then looks at the figures, then reads the discussion, and only reads the methods if they care enough to check your work. Write each section so it makes sense on its own.

The hourglass shape

A good paper starts broad, narrows to your specific question and work, and widens again at the end. This is often drawn as an hourglass.

The shape tells you where each kind of sentence belongs. A sentence about why urban heat matters for public health goes at the top of the introduction or the end of the discussion. A sentence about which satellite images you downloaded goes in the narrow middle. When a section feels muddled, it's usually because sentences from the wide part have drifted into the narrow part, or the reverse.

What each section does

Introduction. Gives the background a smart non-expert needs, says what is already known, points to the gap (the specific thing nobody has answered yet), and ends with your research question or hypothesis. It does not report your results.

Methods. Describes exactly what you did: data sources, materials, equipment, procedures, sample sizes, how you measured each variable, and which statistical tests you used. A reader with the same resources should be able to repeat your work.

Results. Reports what you found, with figures, tables, and numbers. It describes patterns without explaining why they happened.

Discussion. Answers your question directly, compares your findings with earlier studies, explains possible reasons, states the limitations honestly, and suggests next steps.

Conclusion. Some papers and many fairs want a short separate conclusion: one paragraph that restates the answer and its importance. If your format has no conclusion section, the last paragraph of the discussion does this job.

Titles

A title should tell a reader what you studied and, if possible, what you found. Specific beats clever.

Aim for roughly 8 to 15 words. Use words someone would type into a search engine. Avoid abbreviations unless they're more familiar than the full term (DNA is fine; LST is not). A declarative title, which states the finding, works well for a poster. A descriptive title, which states the topic, is safer for a paper whose result is mixed.

Keywords

Many journals and some fairs ask for 3 to 6 keywords, terms that help databases and readers find your paper. Pick words that are not already in your title, since the title is already searched. For the tree project, good keywords would be: urban heat island, Landsat, green infrastructure, impervious surface, environmental justice.

Acknowledgments

The acknowledgments section thanks the people and organizations that helped: your mentor, teachers, anyone who gave you data or lab space, and any funding. Be specific about what each person did. "I thank my mentor for feedback on the statistical analysis and for reviewing drafts of this paper" is better than "I thank everyone who helped me." This is also where you disclose help honestly, which judges and fair rules care about (Chapter 13). Note that the ISEF abstract must not include acknowledgments (Chapter 3), and the ISEF display rules allow mentor and institution names on a poster only in an acknowledgment section (Chapter 8).

References

The reference list, also called a bibliography or works cited, lists every source you cited, in one consistent style. Chapter 5 covers how.
