2026-2027 IrEOES/EOES
The Irish Olympiad of Experimental Science (IrEOES) is an individual science competition for Transition Year and Fifth Year students. The first round takes place online and is accessible to any eligible student who wants to take part. In 2026-2027, you are eligible if you live and go to school in Ireland, are in Transition Year or in Fifth Year, and were born on or after 1st January 2010. We expect to open registration in the middle of September 2026.
2025-2026 IrEOES/EOES
Both Irish teams won a bronze medal at EOES2026 in Lund. This year, the experimental tasks were about sugar and water. In Task 1, the students investigated the growth of sugar beets, sugar extraction, sugar reaction rates, and optical rotation of sugar solutions. Task 2 was about water: students examined algae and dissected fish, took chemical fingerprints of four water samples from across southern Sweden, and looked at sand filtration of drinking water.
We also got to celebrate Odilla Finlayson’s longstanding and outstanding contributions to the science olympiads. Thanks Odilla!
Team training
We had two fun days full of team tasks, bonding, and honing some experimental skills on April 14th and 15th.
Round 3
Round 3 of IrEOES 2025-2026 took place on the Glasnevin campus of Dublin City University on the 15th and 16th of January, 2026. Everybody had fun, learned lots, and made it hard for us to decide on the teams. After 1.5 days of training and a laboratory test we selected Anthony, Davi, Joseph, Róisín, Seán, and Sofiia to represent Ireland at EOES2026.
Round 2
Round 2 of IrEOES 2025-2026 took place on the Glasnevin campus of Dublin City University on Saturday November 22nd 2025. We invited the ~30 best performing students in each subject in Round 1 to take part, and 79 students from all over the country made the trip to DCU.
Congratulations to all medal winners, and thanks to everybody who helped with the organisation.
