Pupils from five Glasgow secondary schools have been competing to win money to run their own Fairtrade businesses.
The winning team came from St Margaret Mary's school
They were taking part in a Dragon's Den-style event at Lourdes Secondary, based on the BBC2 programme.
The students made brief presentations to a panel of judges which included International Development Secretary Douglas Alexander.
Mr Alexander called their ideas "incredibly impressive".
The pupil came from Hillhead, Hyndland, Lourdes, Holyrood and St Margaret Mary's schools.
Mr Alexander said: "They had some really imaginative ideas in terms of how they can raise money for a good cause and they were also a huge credit to their school, to their community, and to their parents in how they presented today."
Took a grilling
The proposals included plans for vending machines selling only Fairtrade snacks, and a cafe selling Fairtrade tea, coffee and hot chocolate before school every morning.
The BBC presenter George Alagiah, who is also a patron of the Fairtrade Foundation, chaired the event. He praised the pupils for their "enthusiasm and ingenuity".
"The amount of Fairtrade sales is doubling every year and you think, how is this happening? Well I just found out sitting at this event. It's the young people that are driving it," he said.
The pupils took a grilling from the Dragon Judges after making their pitches.
The plan for a Fairtrade hot drinks café at St Margaret Mary's School won the first prize of £350.
One of the 15-year-old pupils behind the proposal, Gary Lynas, said he had learned about Fairtrade in geography class
He added: "I just feel it's great to help people who the only way you can help them is through Fairtrade."
