CERN's Beamline for Schools Competition or just BL4S is a scientific competition open to high school students from all over the world with a fabulous prize by any standards: to conduct an experiment for 10 days on-site at CERN in Geneva, Switzerland.

Now entering its fourth year, BL4S has allowed hundreds of schools around the world to experience particle physics research first hand by preparing their proposals for experiments, frequently with guidance from members of the International Particle Physics Outreach Group, IPPOG, and other physicists around the world. Through this competition 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.


And this is not all!  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; while all participants receive a BL4S certificate.

So far, 6 teams have seized this thrilling once-in-a-lifetime opportunity! In 2014, it was Greece and the Netherlands, in 2015, Italy and South Africa and last year, Poland and the UK. Thanks to our amazing donors and sponsors, the 2017 Competition is fully funded and two more teams will be the next ones to see their dreams come true.

In those three years, CERN engaged more than 550 teams of over 5,400 students from around the globe to test their knowledge and skills participating in the competition with a full experimental proposal. You can find out more about the competition and latest updates at this link.
