A school has been awarded a national prize in a competition to make sculptures out of old Yellow Pages directories.

Hardwick Primary School, in Sedgefield, is one of six in the country to win a prize in the Yellow Woods Challenge National Awards.

Pupils from the school are travelling to London Zoo today to collect their award from campaign sponsor, Yellow Pages.

The school will receive a digital camcorder after its creation, called Wallace and Gromit, was rated the second best sculpture in the UK. It was constructed from Yellow Pages that had been collected for recycling.

To mark its success, Yellow Pages has also dedicated trees in the school's name in the Woodland Trust's Bright Lea Wood in Ouston, near Chester-le-Street.

Children took it in turns to build about 20 sculptures with the directories. They built a sculpture, photographed it, took it down then used the directories to build another to enter into the competition.

Headteacher Gill Coulson said: "They really enjoyed building the sculptures and are already asking if they can do it again."
