Build your own LEGO robot, program your robot, and perform a series of measurements inside a closed off “danger zone” that is inaccessible to humans.

Robots are used in many different environments at CERN that are difficult to access or where there could be potential for danger for humans.  CERN scientists have unique experience with designing, building and operating robots for different purposes.  

Find out how magnets work, how they interact with other materials, and how we use magnets in experiments at CERN.

CERN uses thousands of magnets for particle physics experiments. For example, strong electromagnets are used to bend the paths of protons in the Large Hadron Collider (LHC). We can also find strong permanent magnets in particle physics research, for example, inside the AMS particle detector, which is attached to the International Space Station. 

How can we make the invisible visible? Explore how balls interact with a hidden structure to come up with your best model of what the invisible structure is and learn more about the Nature of Science!

A lot of phenomena scientists at CERN investigate are invisible to our eyes! For example, particles cannot be seen with the naked eye, and properties such as their mass, energy and charge can only be determined indirectly. How do scientists design clever experiments to understand things that aren’t visible?

Learn the basics of programming with Ozobot colour codes and discover how we use robots to help us work at CERN.

Mix your own slime and conduct experiments to find out how slimy detectors can help us to make invisible things visible.

A lot of phenomena scientists at CERN investigate are invisible! For example, elementary particles cannot be seen with the naked eye, and properties such as their mass, energy and electric charge can only be determined with the help of powerful research tools like particle detectors. In particle detectors, special materials make invisible properties of particles visible.
