Students from Scotland have scooped top prizes at the prestigious UK Young Scientists and Engineers Fair.
The event, organised by the British Association for the Advancement of Science and held recently in London, showcases outstanding science and technology research projects from students aged 11-19 across the UK.
Rebecca Chroston, of Dollar Academy in Clackmannanshire, was awarded the runner-up prize for best CREST science project for her work H5N1 - When, Not If! She had conducted laboratory tests to detect a virus similar to bird flu and carried out research to investigate and raise people's awareness of it.
She won pound;600 for her school to help fund and support future CREST and science, technology, engineering and mathematics projects, as well as pound;20 in tokens and a trophy.
Sharon Glass, of Park Mains High in Erskine, Renfrewshire, was awarded the Research Council's UK Laboratory Experience prize for her project looking at "dispersibility and particle size analysis of organic pigments". She will be given a privileged view of the experiments taking place at either the Daresbury or Rutherford Appleton laboratory, with the chance to meet scientists who work there.
