Pupils at Whitcliffe Mount School got shirty as they took part in workshops about online safety.
Class discussions were held about dangers faced by young people online, covering topics like cyber-bullying, grooming and identity fraud, and children designed t-shirts displaying online safety messages.
Students were asked to sign an internet safety pledge, promising never to share passwords with anyone online, as well as making banners and television adverts.
The workshop was to help raise the profile of the Child Exploitation and Online Protection Centre where children can report suspicious content online.
Head of English Halima Jogi said: “It was a busy, but incredibly productive and successful day for the English department.”
