TEDxYouth@Berlin Cosmopolitan School 2025: A Celebration of Student Voices on Communication

Once a year, the Berlin Cosmopolitan School becomes a stage for ideas worth spreading—by the students, for the students. At this year’s TEDxYouth@Berlin Cosmopolitan School, the spotlight was on the topic “Communication”. The event, traditionally organized for both the Primary and Secondary School, invited the entire school community to listen, learn, and reflect on how we connect with each other through words, music, movement, and emotion.
Before the students took over the stage, the founder of Berlin Cosmopolitan School shared a few heartfelt words about the importance of listening to the younger generation— especially when they speak from experience, passion, and creativity. Then, the red TEDx carpet was theirs.
What followed was a captivating program filled with original talks, live music, and expressive dance performances. From powerful reflections on bullying, fake news, and social media, to inspiring ideas about intercultural language, underwater communication, and public speaking, the event showcased the depth and diversity of thought among BCS students.
Here’s a glimpse of the performances and talks that shaped this unforgettable day:

✨ As always, TEDxYouth@Berlin Cosmopolitan School was more than an event—it was a mirror to the minds and hearts of our students. We thank every speaker, performer, organizer, and teacher who helped make it possible. You reminded us that communication is not just about speaking—it’s about being heard, being felt, and being understood.

Until next year—stay curious, stay courageous, and keep communicating.
