It’s a bit of both really! Scientists can sign up for this on the IAS website, and then our one sentence descriptions of our work are shown to kids who vote on whether they would like to see us in the main competition or not.
Suzi explained it really well. I think it is really good that people from schools taking part can get involved in choosing the scientists. Did you get a chance to choose the scientists that took part? If not you still get a chance to choose who stays by voting 🙂
