What a load of rubbish - recycled football in action
Pupils played a five-a-side match with a football made from plastic shopping bags, newspapers and magazines at a Carmarthenshire school.
The enterprising Glan-y-Mor students have also produced a recycled scarf which is heading to the prime minister.
Teacher Stephanie Marks said the game was inspired by partner school, Moyeni High in Lesotho, South Africa.
"The idea was that it would be a little like what children would do on the streets in poorer areas," she said. "They just have to make do with the facilities and resources they have."
The kick-around on a designated 'Green Day' was part of the BBC's School Report Sports Day project which coincides with the 2010 World Cup being held in South Africa.
Pupil George, 15, said: "During lunchtime, the pupils took part in a Lesotho-style football competition. The footballs were made in art classes. They were packed tightly, but it was a soft ball which wouldn't go too far. There was a lot of enthusiasm for it."
Bags of fun: Pupils brought in hundreds of plastic bags
Another student, 13-year-old Kate, said she had enjoyed helping to make a huge football scarf which was effectively a petition, heading for 10 Downing Street, as part of the 1Goal project which campaigns for education for all.
The scarf consists of A4 sheets of paper - with hundreds of signatures - and posters linked together.
"The petition will be sent to the Government in the hope that as many children as possible do get full-time education," said Kate. "It's been really fun and I'd love to do it again."
Ms Marks said Glan-y-Mor has taken part in a teacher exchange programme with their South African counterparts.
And children at the Welsh school paid 50p each to take part in a non-uniform day, with all proceeds going to Moyeni High.
Other initiatives have included a maths project looking at World Cup score probabilities and a Spanish-themed slideshow presentation about the tournament.
