As part of the FameLab competition, judges were always looking for somebody who could shine in content, clarity and charisma. These are all important factors to consider in any science talk you are putting together.
The content of the presentation must be scientifically accurate. If the topic chosen has controversy or uncertainty around it, then the talk must acknowledge the opposing views. The scientific topic presented should be well chosen to suit the audience.
Clarity is critical for effective science communication. The structure of the presentation must enable the audience and judges to easily follow the talk and they should be left with a full understanding of the scientific concept chosen.
The audience and judges should be left inspired and enthused about science. The best talks are by a charismatic presenter who makes the science easy to listen to, entertaining and exciting. They should not only be able to communicate the science but share their passion for it and leave the audience wanting to learn more.
