Fibre optics, ants, finches and alcohol are all subjects for prize winning projects at this year's Young Scientist of the Year exhibition.

The overall prize of Young Scientists of the Year was presented to Emma Donnellan and Henry Byrne from St Mary's FCJ School in Bunclody, for their project on a fibre optic liquid analyser. It was the first time the Wexford pupils had entered the competition and they were thrilled and surprised at being named the overall winners.

We knew we had a good project but we didn't know that it was as good as it is.

Other prize winners were Delia Conlon from Muckross Park College in Dublin who looked at the relationship between aphids and ants. The best individual prize went to Gerard Jackson from Dundalk for his project on finches. The group prize went to Mary O'Connor, Martine O'Connor and Josephine Hegarty from Mallow in Cork who studied the production of alcohol from beet molasses.

For the second year running the overall prize was won by a group. Margaret Coyne one of the organisers of the Young Scientist of the Year exhibition says this is not surprising as it is more fun to work in a group and pupils can share their resources and talents.
