From 16 to 18 April 2026, our focus will be on the microscope, a groundbreaking invention which, much like the telescope, has revolutionised our understanding of scientific phenomena. With its help, we will turn our attention to microplastics as one of the most pressing issues of our time. What do we mean by this, where do we encounter it in the environment and in our bodies, and what consequences does this have for our society? Through workshops, fulldome programmes, lectures and live performances, you will experience an exciting journey from the microcosm of life to the infinite vastness of the universe.
You can find all events related to ‘Invisible Worlds: From the Microcosm to the Universe’ here.
The Universe at Your Fingertips
The permanent exhibition at the Zeiss Grand Planetarium brings the cosmos to life through interactive exhibits and tactile experiences that engage the senses. From simulated rocket launches and the ‘spaghetti effect’ of a black hole to planetary surfaces and much more – discover science and astronomy in a whole new, playful way.
Mega-microscopy on the LED wall
Using special microscopes and live projections connected directly to an immersive LED wall, we make the invisible visible: what lies hidden in our surroundings? Visitors are invited to bring along a glass of water from their local pond, a kitchen sponge or other interesting objects, which we will examine together under the microscope
Together with lecturers from the Glass Laboratory and the Marzahn Outdoor Laboratory, we’ll embark on a journey of discovery into the microcosm. Please bring your own samples first to the microscope stations at the Gläsernes Labor or the Freilandlabor Marzahn so that they can be prepared for microscopic examination.
Quiz at the LED wall
Come to the LED wall and test your knowledge of microscopy and microplastics. You can take the quiz on the spur of the moment, or check how much you’ve learnt after visiting the planetarium or attending a workshop. Multiple-choice questions put your knowledge to the test in a fun way and provide surprising ‘aha’ moments.
Helmholtz Imaging
Germany’s largest research organisation, the Helmholtz Association, awards an annual prize for the best scientific image. A selection of the most outstanding entries from the last four years demonstrates how research and aesthetics merge in a fascinating way, offering impressive visual insights at the interface between science and art.
Glass Laboratory:
Experiment Station 1: Microplastics from the beach under the Zeiss stereo microscope
Here, visitors will find samples from German beaches prepared by us. What do they look like under the stereomicroscope? Can microplastics be found in them? Which ones and how many? If so: how big are the pieces, e.g. compared to sand? And: is it even possible to distinguish between the different types of plastic?
Experiment Station 2: Separating different plastics by density
Speaking of distinguishing: that is precisely the problem. There are many types of plastic. To recycle them, they must first be sorted by type. How? That is what this station is all about. Here, visitors can experiment with mixtures of microplastics. Can they be separated by density? (i.e. do some sink to the bottom in water, whilst others float on top?)
The World in Detail – Preparation for Mega-Microscopy
Many details of nature remain hidden from our eyes. Only with magnifying glasses and microscopes can we look more closely and make fascinating discoveries – for example, tiny creatures in moss or surprising structures in everyday objects. In this workshop, you can examine your own finds and create exciting microscopic specimens. Feel free to bring along interesting objects – but please no live animals.
This station serves as preparation for mega-microscopy in the planetarium hall (subject to a fee) and at the LED wall in the foyer. Here, the objects you bring will be turned into microscopic specimens, which can then be viewed on the LED wall or in the planetarium hall.
Information stands
At the exhibition stands, the Freilandlabor Marzahn, the Berliner Mikroskopische Gesellschaft, the Exzellenzcluster »Balance of the Microverse« of the Universität Jena and the Bundesinstitut für Risikobewertung invite you to discover the world of the microscopic from new perspectives. Find out more about modern research methods, exciting projects and the risks posed by microplastics to humans and nature. The Deutsche Meeresstiftung will also be present with an information stand where you can learn more about plankton, the basis of all life in the sea. Here you can see how sensitive this invisible system is to human intervention.
In cooperation with Gläsernes Labor, Freilandlabor Marzahn and the Deutsche Meeresstiftung
