CERN's Beamline for Schools Competition, or just BL4S, is a science competition open to high-school students from all over the world. The prize, fabulous by any standards, is the opportunity to conduct an experiment for 10 days on-site at CERN, located on the French and Swiss border near Geneva.

Now entering its fifth year, BL4S has enabled CERN to engage more than 700 teams of almost 7,000 students from around the globe to experience particle physics research first-hand.

Through BL4S, students test themselves as innovators, problem solvers and collaborators, and are motivated to embark in STEM careers to meet the growing demand for a stronger workforce with STEM skills.

BL4S students prepare proposals for experiments, frequently with guidance from members of the International Particle Physics Outreach Group (IPPOG) and other physicists around the world.

Shortlisted teams win a cosmic-ray detector for their school (introduced for the first time in 2016), a BL4S t-shirt for each team member, and for some, the chance to visit a nearby physics laboratory. All participants in BL4S will receive a BL4S certificate.

The winning teams selected will then travel together to CERN to perform their experiment. So far, 8 teams have seized this thrilling once-in-a-lifetime opportunity! In 2014, it was Greece and the Netherlands; in 2015, Italy and South Africa; in 2016, Poland and the U.K; and in 2017, it was Italy and Canada.

BL4S opens doors for young people to learn and practice science.

We invite you to participate in this effort with a donation to the CERN & Society Programme.
