38,000 visitors in 20 years: high demand shows need for science education
Twenty years ago, on 29 November 2004, Klaus Böger, then Senator for Education in Berlin, opened one of the capital's first school laboratories. Since then, Helmholtz-Zentrum Berlin (HZB), in cooperation with the Berlin Senate, has successfully promoted science education through project days and further training in the school lab.
The HZB School Lab offers hands-on project days for grades 5 to 13 on current research topics such as solar energy, light and colours, and materials research. During the project days, students work in small groups to carry out experiments independently. They are supervised by teachers, scientists and students. The teachers working in the School Lab are funded by the Berlin Senate Department for Education, Youth and Family and are released from their teaching duties for this work.
With around 38,000 visitors over the last 20 years, the demand for such additional science teaching facilities is clearly evident. Thomas Frederking, HZB's commercial director, says: "For 20 years, the School Lab has not only given children and young people an insight into our research, it has also encouraged them to take up scientific careers. In view of the shortage of specialists in these fields, the social value of this commitment is obvious."
In addition to project days for young students, the School Lab also offers trainings for teachers to demonstrate new ways of enriching science lessons. In addition, particularly interested and talented kids and teenagers are supported in two working groups.
"The experiments in the School Lab help to develop critical thinking in young people," says Dr Ulrike Witte, head of the School Lab. "Many school kids only know experiments from YouTube videos - here they experience that experimenting is exciting and not so difficult’. The HZB School Lab will continue to inspire young people's interest in science with a variety of activities in the coming years.

The Helmholtz-Zentrum Berlin für Materialien und Energie is a renowned research centre of the Helmholtz Association. It explores and develops new materials and technologies that will make a contribution to a climate-neutral energy supply in the future. HZB is funded by the Federal Ministry of Education and Research (90 per cent) and the State of Berlin (10 per cent). The establishment of the school laboratory in 2004 was also supported by the Helmholtz Association with 340,000 euros.
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
- 103 schoolgirls on Girls'Day at HZBOn April 3, 2025, the annual Girls' Day took place, giving schoolgirls an insight into various careers in science and technology. We welcomed a total of 103 schoolgirls at our Adlershof and Wannsee sites and offered them a day full of exciting experiments - more participants than ever before!
