This requires some skill with a soldering iron: During Girls' Day, girls got to make earrings shine in their favorite colors.

On 23 April 2026, the annual Girl’s Day took place, giving pupils an insight into various career paths in the fields of science and technology. 83 pupils visited the Adlershof and Wannsee sites and enjoyed a day full of exciting experiments.
By taking part in various workshops, the girls were able to gain an insight into careers such as physicist, engineer and chemist.
Girls’ Day is an important initiative designed to inspire pupils to take an interest in science and technology and to encourage them to pursue careers in these fields.
HZB’s research topics were explored in a fun and engaging way across 16 different workshops.
Wannsee:
- Jules Verne’s dream: water as the coal of the future
- Using colours, electricity and chemistry, we make the invisible visible!
- Kitchen Tetris in the canteen’s shell
- Basics of HTML & CSS
- Atom by atom – thin films for the technology of the future
- Crystals – how are they structured and how can they be studied?
- Creative programming
Smart wires in the student lab
Adlershof:
- Particle accelerators – big and small
- Hot Stuff – solar energy you can touch (almost!)
- Soldering LED earrings
- The daily work of laboratory technicians at HZB and the production of perovskite solar cells
- The power of metadata: tagging, searching, finding!
- Chocolate lithography and what it has to do with solar cells
- Light programming: a creative introduction to programming
- Molecule detectives: searching for clues with NMR
We would like to extend our heartfelt thanks to all our colleagues whose dedication helped ensure that Girls’ Day at HZB could take place with such a diverse and exciting range of workshops.
The next opportunity to get to know us and carry out small experiments yourself will be at the Long Night of Science on 6 June at the HZB Adlershof site. With lots of exciting activities especially for children and young people!
- A frustrated material, and a frustrating synthesisIn condensed matter physics, "frustration" is a technical term: it describes a lattice geometry where competing magnetic interactions cannot all be satisfied simultaneously. This summer at HZB, I have been trying to *make* a frustrated material, and in the process I discovered that the word also describes rather accurately what happens when your sample explodes for the third time in a week.
- A Rainbow on the Way HomeWhen I arrived at HZB for the International Summer Student Programme, I expected to learn about chemistry, new instruments, and research techniques. During the welcome event, each of us received a small gift bag. Inside was a sticker that read, "Science is Diverse."
- When an unexpected result opens a new research directionEvery morning, as I step out of my room and feel the gentle Berlin sunshine on my face, I tell myself, “Today is a brand-new day.” Yet I never imagined that my research journey in Berlin, after joining HZB, would begin with an experimental result that did not go as expected.
