Science Festival at Erasmus MC:
How do you keep a donor organ alive outside the body? What effects do heat and air pollution have on your body? And how do you make a city resilient to extreme rainfall? During the Science Festival at Erasmus MC, children and young people will explore these questions for themselves.
On Saturday 3 October 2026, Erasmus MC, Erasmus University Rotterdam and Delft University of Technology will join forces. The festival consists of three parts: the Convergence project market and short talks, Delft University of Technology’s Science Centre On Tour, and the EUR’s Proefjestuin.
Practical information
When: Saturday 3 October 2026, from 11.00 am to 4.00 pm
Where: De Passage, Erasmus MC, Rotterdam
Who: children and young people aged 8 to 14 and their carers
Admission: free, no booking required
Discover Convergence’s projects
At the project market and during short talks, researchers from Erasmus University Rotterdam, Delft University of Technology and Erasmus MC will demonstrate how they are collaborating on health, technology and the resilient city. Find out, for example, how scientists keep donor organs alive outside the body, what heat and air pollution do to your body, and how to make a square resilient to heavy rain. Visitors can experiment, design, ask questions and meet the researchers. Find the full description of the sessions below.

Science Centre On Tour: discover the science behind top-level sport
What makes a cyclist faster? At TU Delft’s Science Centre On Tour, visitors discover how air resistance affects their speed. They carry out activities on topics such as clothing and cycling posture, before getting on a bike themselves. In a virtual reality environment, they try to cross the finish line as quickly as possible.
EUR’s Proefjes tuin
Walk past various experiments and hands-on activities and discover how science works. Test your reaction time, be amazed by optical illusions and find out how your brain can sometimes trick you. Along the way, you’ll be guided by enthusiastic students who’ll coach you, ask questions and help you set off on a journey of discovery like a real researcher. There’s something for every curious researcher to enjoy!
Collect stickers and receive a Science Certificate
On arrival, young visitors can collect a sticker card. By taking part in the various activities, they collect stickers. When they hand in their sticker card, they’ll receive a real Science Certificate, on which they can write their own name.
Will you be joining us?
You can find all the practical details about the Science Festival at Erasmus MC on the Science Weekend website. So keep an eye on the page for the latest updates: Weekend van de Wetenschap
Morning Program 11.00 – 13.00
3D Brains
Information about the brain is still shared primarily through research articles and textbooks. What if we could bring neuroanatomy closer to curious young minds?
Wanted: virus advisers!
Become a virus adviser and help the government! A new, unknown virus is spreading and the government has to make difficult choices to protect people. You’ll receive the latest information and get to give your advice: are face masks necessary, is it still OK to play together outdoors, or should schools close for a long time? Which measures do you think are sensible?
Can an artificial heart beat just like a real heart?
For people with severe heart failure, a donor heart is not always available in time. That is why researchers are working on an artificial heart that mimics the real heart as closely as possible. Find out how they are trying to create a heart for the future using soft robotics and living tissue.
How much waste is generated by a single hospital treatment?
Gloves, packaging and instruments: a lot of materials are used during a hospital treatment. Take a look at what is used during a bowel examination in hospital and what is thrown away afterwards. Can you sort the waste correctly? And what would you reuse, redesign or do away with altogether?
So you think you can balance?
How does your body stop you from falling over? Step into a special swivel chair and discover how your sense of balance works. Then use a balance board to test how still you can stand. What happens when you close your eyes or stand on an unstable surface?
What will a heat-resilient city of the future look like?
Heat does not affect everyone in the same way. Pregnant women and young children, in particular, can be especially vulnerable. Join our researchers in imagining a climate-just city for today and the future, where everyone receives appropriate protection.
Bloom
Discover Bloom: a playful design that connects children and people in the neighbourhood. Colourful flowers in a window form a code: each colour represents a movement, such as jumping or clapping. This lets people join in from home while children play outside. How will you get the neighbourhood moving?
Afternoon Program 13.30 – 16.00
How do you keep a donor organ alive outside the body?
A heart, kidney or liver cannot simply be left lying around for hours after donation. Discover how researchers use special machines to pump fluid through a donor organ, so that it continues to function outside the body and doctors can assess whether it is healthy enough for a transplant. You’ll also learn about other technologies for the future, from small models of organs to the development of an artificial heart.
How do heat and air pollution affect your body?
Can you tell from your skin or sweat what your environment is doing to your body? Find out how researchers are using tiny sensors and new measurement methods to investigate this. See, for example, how they can measure substances on the skin and how they use tiny models to investigate the effects of heat and air pollution on our cells.
Who gets a say in the future?
Adults make plans for the city’s future. But what do children think about that? And what would it be like if children were allowed to have a say themselves? During this workshop, we’ll explore different futures in a creative way and discover what it means, as a child, to have a say and be involved in deciding what happens in your city. Because your voice counts too when it comes to the future!
How do you make a square that can withstand heavy rain whilst also being pleasant for people?
Take Benthemplein in Rotterdam as an example to discover how a public space can also collect rainwater. Then design your own square featuring trees, rain gardens, permeable paving, water storage, shade and play areas. Can you create a ‘Sponge City’ that works well for both water and people?
Wanted: virus advisers!
The government is looking for virus advisers this afternoon too! A new, unknown virus is spreading and the government has to make difficult choices to protect people. You’ll be given the latest information and can offer your advice: are face masks necessary, is it still allowed to play together outdoors, or should schools close for a long time? Which measures do you think are sensible?
What helps young people stay mentally healthy?
Find out about PROTECt ME’s research into young people’s mental health. See how researchers map feelings and experiences, and discover how prevention and eHealth can help prevent emotional problems. You’ll also be introduced to Grow It!: a fun smartphone app that helps young people better understand their emotions and cope more effectively with challenges.
