Crafting a Winning Science Fair Presentation for ISEF

Whether you’re competing locally, statewide, or nationally, science fairs are no joke. If you’ve finished your project, congrats, you’re halfway there. But to take it to the next level and win big at competitions like Regeneron STS and ISEF, you need an extra push. That’s where your presentation comes in. To give your project real “wow factor,” you need a compelling narrative to go with it.

By the way, Rishab Jain, a Harvard student who won the $50K award at ISEF, has released multiple videos on his YouTube channel about how to win ISEF:

The importance of storytelling in science

At a science fair, you might think the judges care only about the content of your work. You wouldn’t be entirely wrong: a judge should be focused on what you’re saying. But part of your score also depends on how you say it.

Every contestant wants to stand out among dozens of competitors. To do that, you have to present your scientific “story” in a way that makes the judges care about your project, which is harder than it sounds.

Here’s how a compelling presentation can boost your chances of bringing home gold:

• Memorability. Our brains tend to forget stand-alone facts, and a complex project has a lot of them. Put into an interesting context or woven into an engaging story, they’re much easier to remember.
• Shows your passion. Presenting with enthusiasm shows the judges your genuine interest and investment. Judges love to see passion, and showing it earns you a favorable impression.
• Clear communication. Storytelling is an old, skillful way to present important ideas. If a judge can follow a clear storyline in your presentation, you’re more likely to make an impact.

How to create a compelling narrative

Science fair judges look at five basic criteria: creative ability, scientific thought, thoroughness, skill, and clarity. A clear narrative, presented well, can hit all five.

Step 1: Map it out

Before you build your board or draft a script, sketch a basic mind map of how you want each idea to flow into the next. If you jump from topic to topic with no clear links, you can’t fully demonstrate your understanding. It confuses the judges, and it makes you look confused too.

To make your project memorable, don’t word-vomit all your results and hope the judges make sense of them. Instead, weave the facts together into a well-connected, well-articulated narrative. Keep everything organized and plan how to present each piece of information. Don’t aim to memorize, aim to understand and map how your ideas interlink.

Here’s a loose guideline* for how your ideas should connect:

1. Strong opening
2. The problem
3. Strategy
4. Results
5. Impact

*Stay flexible when presenting. Formulas can guide you, but be ready to reroute based on what the judges ask and what feels right. Have a plan, but don’t be afraid to branch off and mix things up.

Step 2: Argue for your project’s importance

To get the judges to believe in your project, convince them your research is both relevant and impactful. Here’s how:

• Be concise and use meaningful details. Less is more: know your core message and stick to it, and the judges will know it by the end too.
• Use evidence. Statistics, graphs, and charts that show your work had the effect you intended. Weave these into your narrative and keep a good balance between storytelling and hard proof.
• Emphasize the most important parts with problem and solution. Who does this impact? Why is it a problem? How does your research contribute to the solution, and why is your research particularly important?

Step 3: Use contradictions

One of the most powerful tools a scientist can use is the word “but.” Contradictions introduce problems and add dramatic effect, grabbing the otherwise wandering attention of audiences and judges.

A monologue with no contradicting statements won’t do you any favors. Stringing your results together with a never-ending series of “and”s makes it sound like you’re just listing facts rather than connecting them. As Bruce Kirchoff wrote in Nature, an ideal structure for your introduction is this: “‘X is the current state of knowledge, and we know Y. But Z problem remains. Therefore, we carried out ABC research.’”

By giving the background first and then introducing the problem with these conjunctions, the most important introductory parts of your project come together in a few smooth sentences.

Step 4: Know your work and your field

Aim for both technical depth and technical breadth. Knowing the intricacies of your project makes for a much smoother conversation with judges. But it’s just as important to understand the broader field, not only the mechanics of your specific research.

Be thorough in both directions. As you go deeper into your project, explore the different avenues of the field and how they connect. Read articles, follow journals and forums, and so on. Judges want to see enthusiasm, and being able to go in-depth shows it. This is the best way to demonstrate your passion and genuine interest in the field, and it helps you explain the whys and hows of your research.

Step 5: Make your board clear and straightforward

Even though you should focus on presenting verbally, judges will also want to pick out the most important points and evidence on your board.

The easier to understand, the better. Use visuals (graphs, tables, photos, 3D models), create clear sections, and keep everything readable. These help break complex concepts into digestible chunks for your audience.

Final step: Make it stick

Good storytelling, paired with polished and diligent research, will take you far in any science competition. I expand on these ideas in my video on my ISEF winning strategies, where I cover all my tips for the world’s top science fair.

Finally, go out there and make yourself memorable. Just participating is rewarding, but do your best to bring home a medal anyway.
