Description

Particle Identities is an online personality quiz developed by the S'Cool Lab team using the open-source GDevelop engine. The quiz helps users explore the properties of elementary particles in a fun and engaging way. Each result introduces a real particle and its basic characteristics, offering a playful entry point into particle physics.

This quiz is available in many languages thanks to volunteer translators, and all particle visuals are kindly provided by The Particle Zoo.

You can start the quiz by visiting the Particle Identities quiz page.

Scientists at CERN study the properties of elementary particles and how they interact. You can learn more about CERN's research programme by visiting the CERN website.

Instructions

• Access the Particle Identities quiz online: cern.ch/identities
• Follow the on-screen instructions to complete the quiz and discover your particle identity.

Ideas for Educators

• Take the quiz: Have your students go through the online quiz on their own to find out which particle fits their personality best.
• Write a particle ID card: The quiz includes a very short description of the respective particle at the end, but you can also encourage your students to find out more about their particle online. Students can, for example, write an ID card for their particle including its name, symbol, mass, electric charge, year of discovery, ...
• Compare particle ID cards: Students can compare each other's particles to find out, which particles share similar properties or which particles can interact with each other because they have the same type of charge.
• Play the quiz inversely: Once students understand the different particle properties, they can play the quiz in the other direction. How do you need to answer the quiz questions to end up as an anti-strange quark? or an electron? or an electron-neutrino?
• Can you find dark matter? A certain (hard to find) answer combination will disclose a hypothetical particle no one has discovered yet, so-called dark matter.
