Below you will find some ideas how to introduce particle physics in your classroom in a hands-on way.

The cloud chamber was one of the first particle detectors. Today, cloud chambers are only used in education. It is very easy to build a cloud chamber with everyday material, dry ice, and Isopropyl alcohol. Below we provide a DIY manual including many information on how to interpret the observations, and what do with cloud chamber (e.g. using balloons as radioactive sources).
The ATLAS detector, the largest particle detector at the LHC, is one the most complex machines ever built. However, due to its complexity, explaining the ATLAS detector at a high-school level can be challenging. Below, we show how to use 3D printers (or straws & cardboard) to build a model of the toroidal ATLAS magnet system. We also suggest learning activities for the physics classroom.
Model for 3D printing: Build your own functional model of the ATLAS toroidal magnet system
- Video "Build your own ATLAS magnet: a functional 3D-printed model"
- 3D Model and student worksheet (ENGLISH)
- 3D compass which can be used to explore the magnetic field of the model
Model with straws: Build a model of the toroidal ATLAS magnet system with everyday material
Bubble chambers were the dominant experimental tools of particle physicists in the 1950s and 60s. They supplanted cloud chambers and lead to the Nobel Prize in Physics 1960. Bubble chambers and cloud chambers work in a very similar way. And although it is not possible to build a bubble chamber in the classroom, students can analyse bubble chamber tracks and learn more about particle identification, e.g. after having built and observed cloud chambers.
This worksheet is based on images recorded by the 2 m bubble chamber at CERN on 10 August 1972. The bubble chamber was exposed to a beam of protons from CERN’s proton synchrotron PS with a momentum of 24 GeV/c. The original pictures as well as the pictured with coloured tracks can be found online: https://cds.cern.ch/record/2307419
Quadrupole ion traps can be used to trap electrically charged particles. At CERN, the GBAR experiment at the antimatter factory uses this particle trap to store anti-hydrogen-ions. Below you can find building instruction for 3D-printable quadrupole ion trap capable of trapping electrically charged "macroscopic particles" such as cinnamon of lycopodium spores. The quadrupole ion trap operates using a 3 kV 50Hz alternating current power supply and uses an astable multivibrator circuit to illuminate the spores, using the stroboscopic effect to exhibit their movement. In addition, we provide worksheets to help students discover the physics behind these traps.
