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.
- Less is more: Why an economical Iridium catalyst works so wellIridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the Iridium, is as efficient and stable over time as the best commercial catalyst. Measurements at BESSY II have now revealed how the special chemical environment in the P2X catalyst during electrolysis promotes the oxygen evolution reaction during water splitting.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
