Upgrade Edition

The Upgrade Edition of the ATLAS Experiment Colouring Book introduces kids to High-Energy Physics through the adventures of student Watty Whiskers and Professor Ducksworth. Kids will discover what it is like to be part of a global scientific team, working together to understand the fundamental building blocks of the Universe and upgrade the world’s largest particle detector for High-Luminosity LHC.

What kids will learn:

ATLAS is one of the world's largest scientific collaborations, bringing together thousands of people from around the globe.
The Universe is made of fundamental particles being studied and discovered by ATLAS scientists.
ATLAS scientists use an experiment to find and identify particles. They are upgrading the experiment with new detector technologies.
ATLAS is a generational experiment: the Higgs boson was discovered in 2012, and today new scientists are using the experiment to search for the next discoveries.
There are many ways to be an ATLAS scientist: from building detectors and studying particles to teaching students and working in the control room.
Scientists are made through learning, curiosity and teamwork. Anyone can become an ATLAS scientist.

Guide for Parents and Teachers

This guide will help parents and teachers discuss the subjects addressed in the ATLAS Colouring Books. It isn’t an encyclopaedia of all of particle physics; instead, it provides a general overview of both the science and the research for non-experts. The guide will enhance your understanding of the field so you can feel more comfortable in sharing your knowledge with kids. It will also provide you with a list of resources in case you want to learn more about some topics.

Questions addressed:

What is particle physics?
How does the Large Hadron Collider work?
What is the Standard Model of Particle Physics?
What are particle generations and colour charge?
What about antiparticles and cosmic rays?
Have physicists discovered everything?
How can you work at ATLAS?

ATLAS Virtual Visits

A Virtual Visit is a live video connection by a group (typically a classroom) to the ATLAS Experiment at CERN. A guide, who is a scientist or an engineer working on the experiment, meets visitors from the control room or (during planned LHC shutdowns) from the detector underground.

During a Virtual Visit, guides will

Introduce themselves and describe their work in particle physics.
Present CERN, the Large Hadron Collider (LHC), and the ATLAS experiment, including its goals and accomplishments.
Invite questions from the audience.

We recommend audiences prepare questions ahead of time. This can be facilitated by viewing this introductory video.

Group Virtual Visits

Groups of at least 10 visitors (such as classrooms) can schedule their own visit by completing this form.

Visit Description

This virtual visit is organised for Higher Physics students at a small school in Scotland. The students will begin their study of particle physics around the time of the visit. Some students have already been introduced to the Standard Model, while others may have this visit as their first opportunity to explore it.

The visit will offer students an engaging introduction to particle physics, helping them connect ideas they encounter in the classroom with research and discoveries in Particle Physics.
