Tehran – Iranian students won four silver medals at the 57th International Chemistry Olympiad (ICHO) held in Dubai, United Arab Emirates from July 5th to 14th.
The event brought together 360 students from over 90 countries to explore competition, cooperation, challenge solving and innovation.
Each participating country sent a team of four students and two mentors. Students competed in a rigorous five-hour laboratory practice exam and another five-hour theoretical exam, usually preceded theoretical exam.
The Iranian team consisting of Sina Ahani, Seyed Taha Hosseini, Seyed Amir Hossein Taheli Tali and Mohammad Kefari Alamdali have won four silver medals.
ICHO is designed to promote interest in chemistry by challenging students with complex, creative chemical problems. Beyond competition, it aims to promote international cooperation, build friendships among young scientists from various countries, and promote exchange of scientific and educational expertise.
Participants are ranked based on their score, not as a team. Gold medals will be awarded to the top 12% of students, silver to the next 22%, and bronze to the next 32%.
The top 10% of non-medalists receive honorable mentions. Special awards will be awarded to students with the highest overall score and those with the highest scores in theoretical and practical exams.
To excel at Icho, you need to have a deep understanding of chemistry, the ability to interconnect various chemical concepts, and practical application skills. This competition not only rewards excellence, it also inspires future generations of chemists around the world.
The concept of Ginkgo was born in 1968 in the former Czechoslovakia, and its first event was held in Prague from June 18th to 21st of that year. Since then, except in 1971, Olympiad has been held annually.
Initially, participating delegations were mainly from the eastern bloc countries, but in 1980 Austria became the first non-Eastern bloc country to hold events.
