Science Fair 2025
Science Fair 2025! The long-awaited and extremely inspiring scientific exhibition Science Fair took place at Zlatarski International School! As every year, our students shone with creativity, curiosity and enthusiasm, presenting impressive projects in biology, chemistry, physics and computer science.
Each stand was a true laboratory of ideas, where knowledge came to life and new discoveries were born. Students not only demonstrated scientific concepts but also displayed in an exciting way how they find real-world application.

This year’s projects were colorful and diverse:
6. Grade presented intriguing topics such as “Solar panel”, “Vertebrates and invertebrates” and “Stability of bridges” – real little researchers with big ideas!
7. Grade impressed with the “Magnetic slime” project – science and fun in one!
8. Grade got involved with interesting experiments such as “Electric circuit”, “Conductors and insulators” and many more.
9. Grade presented amazing projects such as “DNA model”, “Color changing magic potion”, “Infinity mirror”, “Model of circulatory system” and more – a real laboratory of the future!
10. Grade made experiments such as “Dry ice experience” and “How do different drinks affect tooth enamel” – impressive and instructive!

The students of Grade 11 in the prestigious IB Diploma Programme presented their Group 4 projects – impressive scientific studies in biology, physics and chemistry to students from lower classes.
Stefania, Chanel and Stephanie explored the growth of bacteria and possible treatments. Miroslav and Raya talked about the effect of light on photosynthesis in radishes. Arnav, Shrikrishna and Ilia analyzed how temperature affects the speed of tea diffusion in water. Iva, Matilde, Kristian and Emil presented a study about potato osmosis and the impact of water density.
Our students proved that academic knowledge, brave questions, and confident public speaking go hand in hand.
And the students from smaller classes? They are already eagerly planning their own scientific experiments for the next Natural Sciences Week at Zlatarski International School.

Thank you from the heart to all young researchers for their work, inspiration, and desire to share their ideas! Congratulations also to the teachers who support them and ignite the scientific spark! Science, experiments and inspiration during Science Week at Zlatarski International School!
