Found a Topic You Like? Here’s What To Do Next…

Now that you’ve picked a science presentation topic that excites you, let’s get ready to put our presentation together.

  • Gather accurate facts: Seek credible sources for additional information on your topic. The National Institutes of Health (NIH) website contains fact-checked and up-to-date information on hundreds of scientific topics. For example, here is a page on the National Human Genome Research Institute (NHGRI) website with tons of ready-to-use resources on the human genome.

Scientific association websites, such as the Society for Neuroscience or the American Association for Cancer Research, also contain trustworthy information on their respective topics.

Reputable science news outlets, such as ScienceNews or EurekaAlert are great sources for recent articles on your topic.

  • Develop your thesis statement: Get clear on your main message. Ask: What’s the one thing I want my audience to know, do, or feel at the end of my presentation?

Remember, while it’s helpful to share your opinions and experiences in your presentation, you need to support your main points with real facts or robust data.

  • Conduct an audience analysis: Think about who you’re speaking to. What’s their level of knowledge? What will grab their interest? What are they expecting from you (the presenter)? Once you know your audience better, modify your presentation content to suit their profile.
  • Pick a presentation style: Will your presentation be informative or persuasive? Information presentations include how-to, step-by-step guides, ‘did you know’ trivia, the history of a topic, and so on. Meanwhile, persuasive presentations share a new perspective, a strong point of view, unknown truths, and so on.

Either style works for science presentations. So, choose what works best for your topic and audience.

With these steps, you, my friend, are well on your way to delivering an engaging and memorable science presentation. Now, go show ’em how it’s done!
