That is where real science is happening. Science lives on the edge of what we understand. If this is an interesting topic, the research that answers some questions will have raised new ones. Tell your audience where the research is headed now. Now it's time to put the final touches on your presentation.
Students use a variety of techniques to tell the story.
Overhead transparencies, PowerPoint presentations, models, slides, and demonstrations are all useful. Just be sure you are comfortable with whatever you are using. Make sure that the audience can see what you are talking about. If the print is too small or you only show something for 5 seconds, no one will get the point you are trying to make. If you are showing data or illustrations, make sure you indicate where you got the information.
