The European Olympiad of Experimental Science (EOES) is an annually held team-based science competition for the European Union's (EU) school students to display their capabilities in natural sciences.
Since 2021, the EOES has replaced the identically structured European Union Science Olympiad (EUSO), which was founded in 2003, following a rift with its founder and president Michael A. Cotter of Dublin, Ireland, in the wake of the cancellation of EUSO 2020 due to the COVID-19 pandemic. The competition is open to second-level-school, or secondary school, science students who are 18 years of age or younger prior to the competition. Each participating country sends two three-student teams who compete in two intellectually challenging and collaborative tasks. The tasks are designed to connect the branches of science, provide relevant and inquiry-based challenges, engage all team members, support self-pacing, prompt higher-order and creative thinking, and encourage substantive communication.
History
The competition was founded in 2003 by Dr. Michael A. Cotter, of Dublin, Ireland. Dr Cotter had founded the Irish Science Olympiad (ISO) in 1994 and he aimed to create a more practical-based general science competition for young EU students. From 2003 to 2020 the competition was named European Union Science Olympiad (EUSO). In 2021 the name was changed to European Olympiad of Experimental Science (EOES).
