This year the BT Young Scientist and Technology Exhibition (commonly known as the Young Scientist Exhibition) takes place at the R.D.S. in Dublin from the 9th to the 12th of January and comprises 550 projects presented by second-level students from throughout Ireland.

RTÉ Archives takes a look back at past exhibitions. Firstly, a RTÉ News report from 7 January 1981 from the Aer Lingus Young Scientist Exhibition at the R.D.S., Dublin. Almost 800 entrants from all over Ireland entered individual and group projects, including 80 from Northern Ireland. This report by Colm Connolly shows preparations under way prior to the opening of the exhibition. A prize fund of £6,500 will be shared among exhibitors, schools and teachers. Projects range from Ireland's involvement in the European space programme to how much tax farmers should pay.

Now in its 49th year, the Young Scientist Exhibition has been held every January since 1965. While the competition is currently sponsored by BT Ireland, it was previously sponsored by Aer Lingus for 33 years. Prizes are awarded in the categories of biology, physics, technology, and social and behaviour sciences.

The 'Young Scientist Exhibition' as it is commonly known was set up by two UCD physics researchers, Dr. Tony Scott and the late Rev. Dr. Tom Burke in 1965.
