On 19 November 2025, our school came alive with the spirit of the Fête de la Science, celebrated for the first time in Germany under the patronage of the French Embassy. We had the privilege of hosting Dr Christian George, CNRS researcher and Deputy Director of the Institute for Research on Catalysis and the Environment (IRCELYON).
This event—the second session organised as part of the Fête de la Science—left a lasting impression on students from Première, Terminale and CM2, all united by a common goal: better understanding the world around them.
The morning began with a captivating lecture for Première students on a key topic: air pollution. With clarity and enthusiasm, Dr George explained:
- Where pollution comes from (industry, transport, urbanisation)
- What happens in the air (ozone, nitrogen oxides, fine particles)
- Its impacts (health, climate, biodiversity)
- Potential solutions (catalysis, cleaner fuels)
Students then had the opportunity to engage directly with him, asking insightful questions and discovering the realities of scientific research.
In the second part, Terminale students worked on Étonnante Chimie, a book to which Dr George contributed. Focusing on the chapter “At the Ocean’s Surface”, they explored:
- Photochemical reactions at the air–sea interface
- The role of surfactants and biofilms in aerosol formation
- Climate and health impacts of fine particles
- Ocean–atmosphere interactions essential for global climate systems
Having prepared in advance, the students were able to hold an in-depth discussion with the researcher, making the session both interactive and highly enriching.
To close the day, Dr George met with the CM2 A and B classes. Using simple language and concrete examples, he introduced them to aerosols—tiny particles suspended in the air, originating from the sea, volcanoes or human activity. A playful and accessible introduction that sparked their curiosity and environmental awareness.
This event reflects the LfiSV’s commitment to making science engaging and accessible by bringing students closer to researchers and showing them how scientific inquiry can help address tomorrow’s challenges.
A heartfelt thank you to Dr Christian George for his enthusiasm and generosity, to Mrs Maria Abi Chebli for coordinating this memorable day, and to our students and teachers for their dedication and engagement.
