Beamline for schools

CERN is offering high-school students from around the world the chance to create and perform a scientific experiment on a CERN accelerator beamline. What better way to learn about physics? Now in its fourth year, the Beamline for Schools competition is open to teams of at least 5 students aged 16 and up with at least one adult supervisor, or "coach". Find out about the beamline and facilities via, then think of a simple, creative experiment. Submit your written proposal and short video by the end of March 2016. Previous winners have tested webcams and classroom-grown crystals in the beamline, others have studied how particles decay and investigated high-energy gamma rays. What would you do?

Prizes: All participants will receive a certificate. Shortlisted teams will win a BL4S t-shirt for each team member, a cosmic-ray detector for the school and, for some, the chance to visit a nearby physics laboratory. For the winning team(s), nine members and up to two adult coaches per team will be invited, all expenses paid, to CERN for one week to carry out the experiments on the beamline.
