Young Scientists from American College Arcus -Honored for Their International-Level Research Achievements!
Students from grades 9c and 11c class, specializing in Natural Sciences at American College Arcus, participated in the 11th edition of the International Science Fair Fission 2026, held on April 17–18, 2026, at the American College of Sofia.
The prestigious international forum featured innovative experimental projects and models presented by participants from Bulgaria, Turkey, Hungary, North Macedonia, and Romania. The projects were evaluated by an international jury composed of scientists and researchers from various fields of natural sciences.
Inspired by the challenges of science, our students developed their own experimental designs aimed at exploring processes and patterns that spark their curiosity. Their research results and presentations impressed both the jury and the visitors with their depth, scientific approach, and original contributions.
We are proud to announce the achievements of our young researchers in the Biological, Biomedical & Chemical Sciences category:
• Honorable Mention awarded to Kalina Borislavova Borisova and Katerina Danielova Georgieva (Grade 9c) for their project:
