Scattering experiments (e.g. the gold foil experiment) are important research tools of nuclear and particle physics. They help us to study interactions between particles and to obtain information about the structure of matter. Below, we present activities using a mechanical 3D-printable...

Mystery boxes are a great tool to practice sci­­­entific reasoning skills and introduce students to the power of scientific models. Students develop hypotheses about the internal structure of a mystery box and come up with ideas on how to test their hypotheses. They also learn about the...

Quarks are fundamental particles in the Standard Model of particle physics. They make up the protons and neutrons that we are familiar with, but also a zoo of other more exotic particle systems like pions and kaons. Quarks have never been isolated; they always form groups of two or three. But...
