From the main menu there are three links leading to the interactive components. You can try the first component after reading about hadrons in Hands-on-CERN. The other two are more challenging, for these you need to read the text in The Fireworks of Particles.
Play with elementary particles!
Here you can combine quarks to learn how different hadrons have different
quark contents.
Play with Feynman diagrams!
Physicists use Feynman diagrams to picture how different particle reactions looks like.
If you click on this link, you can experiment yourself with some Feynman diagrams
and see how different particle reactions are related to each other.
Try to unfold a hadron decay step by step!
This is the most challenging exercise; here you can test yourself to see how much you
know about elementary particles. The task is to construct different particle reactions.
To accomplish this, you must know the composition of quarks for different hadrons,
and also know how Feynman diagrams works.
