Students in Southsea will write messages about what they enjoy most about the web to celebrate Safer Internet Day.
St John’s College pupils are taking part in the national initiative, which promotes the safe and responsible use of technology.
The college is running a competition where students write messages on specially-designed hearts. They can include suggestions on what they would improve about the internet.
The entries will then be judged by a press officer from the University of Portsmouth, and the winner will receive a new iPod.
In addition, to the competition, several year groups will be having e-safety awareness assemblies.
A question wall set up in the senior school library for pupils looking for help, advice or answers.
Each entry to the St John’s College competition will be shared via the school’s Twitter profile @SJCSouthsea with the hashtag #shareaheart.
