School kids show talents for charity

Youngsters at Fulwood High School and Arts College in Preston will show their talents to raise money for sick children. It is putting on a wonderful show on Thursday November to support Derian House Children’s Hospice(安养院)near Chorley.

Pupils are planning a night to remember, with a wide range of acts from singers and dancers to a magician. Local band Vox Population, fronted by former pupil Laurence Holt, will be playing following their recent tour of Germany. The best part of the night will be a surprise act by a group of teachers.

Tickets are available from the school priced £1.50 for pupils and £2 for adults. The show starts at 7 pm.

Grants(补助金)aim to boost recycling

Children and community groups across Lancashire have been given help to recycle more. More than 40 schools, organizations and community groups have received Waste Action Grants.

Brinscall Primary School in Chorley has been awarded 500 pounds to provide money for its Infant Fruit Waste project. The money has been used to buy a Roly Pig composter that will turn fruit waste into compost(堆肥).

Carole Lormer, from the school, said, “The children completely love the Roly Pigs. They have been feeding and turning them every day, using leftover fruit.”
