During my time at Sense About Science one of my main responsibilities has been running the Energy Panel and the Plant Science Panels and for me this has been some of the most interesting work. The panels are made up of experts in the respective fields, who have made themselves available to answer public questions. As part of my responsibilities I field questions from the public, choose the appropriate scientist to answer (in the case of the Plant Science Panel there are over 50 different specialists), then if necessary edit the answer to make it more readable, before publicising it.
So what is the point in getting scientists to answer public questions?
