The judges are looking for somebody who shines in terms of content, clarity and charisma.
The content of the presentations must be scientifically accurate. If the selected topic is controversial or includes an element of uncertainty, then the presentation must acknowledge 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 winner will be a charismatic presenter who makes the science easy to listen to, entertaining and exciting, and who is not only able to communicate the science but can also share their passion for it.
