Lancaster Royal Grammar School pupils have raised more than £16,000 in the past year through individual activities or events organised by forms.
A host of events were organised ranging from comedy events, a shoe shine, to quizzes and raffles and a whole school run.
Staff joined in as well, with the headmaster eating chillies for charity.
The school has a Charities Committee made up of pupils and members are involved in selecting which charities are chosen.

This year the money has been shared with Slynedales Cancer Care, Animal Care Lancaster, Parkinson’s UK, Friends of Mulanje Orphans (Malawi) and Humanity First. Headmaster Dr Chris Pyle said: “Support for charities both in our local area and around the world is an important part of school life at LRGS.
“I am delighted to see our pupils taking the initiative in choosing suitable causes and raising thousands of pounds in so many creative ways.
“It was great to be a part of our pupils’ weird and wonderful fund-raising schemes, from very enjoyable cake sales to quite a painful chilli eating competition.
“All of us have been struck by the amazing work of our chosen charities this yea and I hope that many of our pupils will be inspired by their involvement with them.”
Quaddous Ahmed, from Humanity First, told pupils : “You are superheroes and are helping to change the world.”
Penny Darby from Cancer Care said: “Thank you very much for supporting Cancer Care. We support families who are affected by cancer and this donation will help us to continue offering this much needed service.”
