Coláiste Muire has a strong tradition of participation and success at the Young Scientist.

In 2011, three Coláiste Muire students took home the overall group award and there has been lots more success and participation since then.

What a year for Coláiste Muire at the BT Young Scientist and Technology Exhibition 2019!


Peter Lehane wowed the judges and the public with his Media Meddling with Memory study, which was judged to be ‘the most outstanding work across all categories in the social and behavioural sciences’. He was chosen for the prestigious RTE Student award, as well as being awarded first place in his category individual intermediate social and behavioural sciences. Peter’s work was then moved alongside the other five top projects in the entire exhibition, where on Saturday he was bombarded by media and the public. He then was interviewed on 2fm, where he continued to impress.

Rachel Cotter and Jack Mullen were awarded second place in the highly competitive intermediate biological and ecological sciences category, for their work ‘Fish to Fork – ingestion of microplastics by commercial fish off the Irish South Coast’. The icing on the cake came when they were announced as winners of the Unge Forskere Award, for which their work was chosen to represent Ireland in the Danish Young Scientist competition in Copenhagen this coming April.

Shane Williams

The judges highly commended Shane Williams for his work on sexual orientation and anxiety, drug and alcohol use and school absenteeism.


Róisín Duffy

Roisín Duffy impressed judges with her novel approach to teacher student interactions. In her project ‘Talk to the Hand’ she looked at how students respond to ‘rudeness’ from a teacher.

Ms McMahon was also short-listed for the BT Educator of Excellence Award. This award honours teachers whose commitment and encouragement have consistently enabled their students to participate successfully in all categories of the exhibition.

To say that Team Crosshaven – Olivia Gavin, Roisin Duffy, Shane Williams, Rachel Cotter, Jack Mullen and Peter Lehane, with the help of their teachers Martina McMahon and Bridget Lehane did us proud is such an understatement.

These six students, with their five projects, far exceeded all expectations. How they represented their school, how they presented their work to the public, and how they impressed the judges was just incredible.

Congratulations to Team Crosshaven for their incredible week at the BT Young Scientist and Technology Exhibition. We are so so proud of you
