Samantha Wilkinson, a year nine student at the Dixons city technology college in Bradford, investigates a Bart Simpson model designed as part of a project to help children understand asthma.

The students worked with Shipley Health Centre practice nurse Dilys Bruce (left) on the project, which was devised to encourage children to attend an asthma clinic.

Non-attendance at the clinic can be as high as 50 per cent.
